D2.Psy.21.9-12: How Psychological Science Can Address Domestic and Global Issues
In plain English: D2.Psy.21.9-12 is the C3 Framework psychology indicator for grades 9-12 that asks students to discuss ways the applications of psychological science can address domestic and global issues. Students trace how a finding about thinking, feeling or behavior becomes a program, how that program is tested, and why it must be checked again before it is used in another community or country.
Discuss ways in which the applications of psychological science can address domestic and global issues.

D2.Psy.21.9-12 asks students to discuss ways in which the applications of psychological science can address domestic and global issues. A domestic issue is a problem inside one country (on this page, the United States); a global issue crosses borders or is shared by many countries. The lesson follows one idea through every source: psychological science helps with an issue when a claim about how people think, feel or act is turned into a practice, and that practice is tested and then checked again in each new setting.
Students read two historical sources and two current federal sources, all named in the text where they appear: Lightner Witmer's 1907 article on his psychological clinic for Philadelphia schoolchildren (a domestic issue), the psychologist William James's 1910 essay on the psychology of war (a global issue), FEMA's Ready.gov page on coping after a disaster, and the NIMH Center for Global Mental Health Research page. A fifth source is an invented study with invented data. Students compare the kinds of evidence behind each application, flag historical views that are now outdated, and plan a test of their own on paper only.
Learning Objectives
By the end of this lesson, students will be able to:
Tell a domestic issue from a global issue, and explain why some issues are both
Describe how a psychological claim becomes an application: understand the issue, design a practice, test it, adapt it
Discuss, with quotations, how four sources from 1907 to 2026 apply psychology to a domestic or a global issue
Judge the evidence behind an application: case reports, argument, guidance, a research agenda or an experiment
Explain why a program tested in one community must be checked again before it is used elsewhere
Prior Knowledge Required
Students should already be comfortable with:
Experiments, random assignment and the limits of a sample D2.Psy.1.9-12
Suggesting ethical, psychology-based solutions to real problems D2.Psy.20.9-12
"Name one problem that many people face, either in your own town or across the world. What would you need to know about how people think, feel or act to make it smaller?"
Pairs write one problem and one "people question" on a sticky note. Post the notes in two columns, In one country and Across borders, and leave a space between them for problems that belong in both. Keep the notes up: students return to them in Closure.
Direct Instruction20 minutes
Key terms.Psychological science is the scientific study of behavior and mental processes. An application uses what that science has learned to change something outside the laboratory: a school, a clinic, a public message, a program. A domestic issue is a problem within one country; a global issue is shared across borders, such as war (Source 2) or improving mental health care in many countries (Source 4). Many issues are both: disasters strike one county, but they happen in every country.
Four moves in applying psychological science (written for this page)
Move
Question it answers
Example from this page
Understand
What thoughts, feelings or habits keep the problem going?
Witmer examines each child who is falling behind in school (Source 1)
Design
What practice could change them?
A worksheet that turns "make a plan" into three concrete blanks (Source 5)
Test
Did the practice work, compared with what?
Two randomly chosen groups of households, one with the worksheet (Source 5)
Adapt
Will it work for other people in other places?
NIMH funds research that adapts interventions to communities (Source 4)
Read Source 1. Lightner Witmer directed the psychology laboratory at the University of Pennsylvania; this passage opens his article "Clinical Psychology," printed in 1907 in the first issue of the journal The Psychological Clinic. Outdated view: Witmer's phrase "moral defects" labels children rather than describing what they do, and elsewhere the article uses terms such as "retarded" that are no longer used for children who learn differently. Today's educators describe a specific need and the support that helps.
1During the last ten years the laboratory of psychology at the University of Pennsylvania has conducted, under my direction, what I have called "a psychological clinic". Children from the public schools of Philadelphia and adjacent cities have been brought to the laboratory by parents or teachers; these children had made themselves conspicuous because of an inability to progress in school work as rapidly as other children, or because of moral defects which rendered them difficult to manage under ordinary discipline.
2When brought to the psychological clinic, such children are given a physical and mental examination; if the result of this examination shows it to be desirable, they are then sent to specialists for the eye or ear, for the nose and throat, and for nervous diseases, one or all, as each case may require. The result of this conjoint medical and psychological examination is a diagnosis of the child's mental and physical condition and the recommendation of appropriate medical and pedagogical treatment. The progress of some of these children has been followed for a term of years.

3Although clinical psychology is closely related to medicine, it is quite as closely related to sociology and to pedagogy. The school room, the juvenile court, and the streets are a larger laboratory of psychology. An abundance of material for scientific study fails to be utilized, because the interest of psychologists is elsewhere engaged, and those in constant touch with the actual phenomena do not possess the training necessary to make their experience and observation of scientific value.

Then read Source 2, from William James's essay "The Moral Equivalent of War," first published in 1910. James asks why nations keep choosing war and whether the feelings behind it could be turned to peaceful work. Outdated views: the essay writes as if the "youthful population" it would draft were young men, judged by how "the women would value them," and it treats nature as an enemy to be conquered. James's plan was an argument, not a tested program, and whether any national service is a good idea is a question on which people disagree: students judge his reasoning, not the policy.
1The war-party is assuredly right in affirming and reaffirming that the martial virtues, although originally gained by the race through war, are absolute and permanent human goods. Patriotic pride and ambition in their military form are, after all, only specifications of a more general competitive passion. They are its first form, but that is no reason for supposing them to be its last form. Men now are proud of belonging to a conquering nation, and without a murmur they lay down their persons and their wealth, if by so doing they may fend off subjection. But who can be sure that other aspects of one's country may not, with time and education and suggestion enough, come to be regarded with similarly effective feelings of pride and shame? Why should men not some day feel that it is worth a blood-tax to belong to a collectivity superior in any ideal respect? Why should they not blush with indignant shame if the community that owns them is vile in any way whatsoever? Individuals, daily more numerous, now feel this civic passion. It is only a question of blowing on the spark till the whole population gets incandescent, and on the ruins of the old morals of military honor, a stable system of morals of civic honor builds itself up. What the whole community comes to believe in grasps the individual as in a vise. The war-function has grasped us so far; but constructive interests may some day seem no less imperative, and impose on the individual a hardly lighter burden.
2Let me illustrate my idea more concretely. There is nothing to make one indignant in the mere fact that life is hard, that men should toil and suffer pain. The planetary conditions once for all are such, and we can stand it. But that so many men, by mere accidents of birth and opportunity, should have a life of nothing else but toil and pain and hardness and inferiority imposed upon them, should have no vacation, while others natively no more deserving never get any taste of this campaigning life at all,--this is capable of arousing indignation in reflective minds. It may end by seeming shameful to all of us that some of us have nothing but campaigning, and others nothing but unmanly ease. If now--and this is my idea--there were, instead of military conscription a conscription of the whole youthful population to form for a certain number of years a part of the army enlisted against Nature, the injustice would tend to be evened out, and numerous other goods to the commonwealth would follow. The military ideals of hardihood and discipline would be wrought into the growing fibre of the people; no one would remain blind as the luxurious classes now are blind, to man's relations to the globe he lives on, and to the permanently sour and hard foundations of his higher life. To coal and iron mines, to freight trains, to fishing fleets in December, to dishwashing, clothes-washing, and window-washing, to road-building and tunnel-making, to foundries and stoke-holes, and to the frames of skyscrapers, would our gilded youths be drafted off, according to their choice, to get the childishness knocked out of them, and to come back into society with healthier sympathies and soberer ideas. They would have paid their blood-tax, done their own part in the immemorial human warfare against nature; they would tread the earth more proudly, the women would value them more highly, they would be better fathers and teachers of the following generation.

A domestic issue at the scale of one child: Source 1
Which issue does Witmer's clinic address, and what does the clinic do with each child?
Result: The issue is children in Philadelphia-area public schools who show an "inability to progress in school work as rapidly as other children" (paragraph 1), a domestic issue. The clinic examines each child and, where needed, "they are then sent to specialists for the eye or ear, for the nose and throat, and for nervous diseases" (paragraph 2). The application is a combined medical, psychological and teaching plan for one child at a time, and Witmer's evidence is the progress of the children he followed.
A global issue and a psychological argument: Source 2
What psychological claim does James make about war, and what does he think could replace military pride?
Result: His claim is that military pride is one form of a wider human motive: "Patriotic pride and ambition in their military form are, after all, only specifications of a more general competitive passion" (paragraph 1). He asks whether other aspects of one's country may not, with time and education and suggestion enough, come to be regarded with similarly effective feelings of pride and shame (paragraph 1), that is, whether pride in civic work could carry the same force. The evidence is reasoning from history and observation; James does not test the claim.
Guidance to the public: Source 3
Ready.gov writes, "Profound sadness, grief and anger are normal reactions to an abnormal event." Why would a disaster agency put a sentence about emotions on its website?
Result: The sentence (paragraph 5) treats strong feelings as an expected part of recovery, not a sign that something is wrong with the person. The page then links naming feelings to recovery ("Acknowledging your feelings helps you recover," paragraph 6) and lists practical steps, such as keeping "a normal family and daily routine" (paragraph 15). The page states guidance; it does not name the research behind it.
A global research agenda: Source 4
Why does a United States institute fund mental health research in other countries, and what does that research add?
Result: Source 4 says the research aims to improve mental health "in the United States and abroad" (paragraph 2), and it names work on "developing and adapting evidence-based interventions to the unique needs of communities and settings" (paragraph 5). A practice that helps in one place is a hypothesis in the next place until it is tested there.
Reading an invented test: Source 5
In Source 5 (Guided Practice), what percent of each group of 150 answered yes?
Result: Group A: 27 / 150 = 0.18, so 18%. Group B: 45 / 150 = 0.30, so 30%. The worksheet group answered yes more often, by 12 percentage points, which matters only because the households were split at random.
Close the segment: Which of the sources so far report a test of an application? Only Source 5, an invented one, does. Source 1 reports cases, Source 2 is an argument, Source 3 is guidance and Source 4 is a plan for research. Each is a different step on the way from a claim to an application.
Guided Practice15 minutes
Read Source 5 together. It is an invented study with invented data, written for this page to show how an office could test one application of psychological science to a domestic issue: getting households to prepare for a disaster.
1Invented study summary, written for this page. The county, the office and every number are invented. A county emergency office wanted more households to write a family disaster plan. In March it chose 300 households at random from the county's address list and split them at random into two groups of 150.
2Group A received a one-page flyer that listed reasons to make a plan. Group B received the same flyer plus a fill-in worksheet with three blanks: the place where the family would meet if they had to leave home, the out-of-town person every family member would call, and the date on which the family would sit down to fill in the plan.
3Six weeks later, volunteers phoned every household and asked one question: "Does your household now have a written disaster plan?" In Group A, 27 households answered yes, and 15 could not be reached. In Group B, 45 households answered yes, and 30 could not be reached. Households that could not be reached were counted as not having a plan.
4The office concluded that the worksheet works and that it should be mailed to every household in the state.
SVHS (invented scenario), Source 5: The disaster-plan worksheet (invented study with invented data) (2026). Original passage written for this page.
Variables. What did the office change between the groups, and what did it measure? (It changed the mailing: flyer only or flyer plus worksheet. It measured the answer to one phone question.)
Design. Why does it matter that the 300 households were chosen and split at random? (The groups should be alike in everything except the mailing, so a difference in answers can be traced to the worksheet.)
Measure. Paragraph 3 counts a household that could not be reached as having no plan. Who might be harder to reach, and how could that rule change the comparison? Students find the counts in paragraph 3 and discuss; the reached-only percents are left for homework.
Conclusion. Paragraph 4 says the worksheet "works" and should be mailed statewide. Name two things the study did not show. (It did not check that plans were written, only that people said so; it did not show that the plans helped in a real disaster; it tested one county.)
Discuss: the worksheet applies an idea the office treats as a hypothesis, that a goal is easier to act on when it is broken into specific steps with a place, a person and a date. If a country on another continent wanted to use the worksheet, what would have to change, and what would have to be tested again? Connect the answer to the word "adapting" in Source 4.
Independent Practice15 minutes
Students read Sources 3 and 4 on their own. Source 3 is FEMA's current Ready.gov page on coping after a disaster, a domestic application written as public guidance. Source 4 is the National Institute of Mental Health page describing its Center for Global Mental Health Research. The quiz and homework use all five sources.
1Disasters are upsetting experiences for everyone involved. The emotional toll that disaster brings can sometimes be even more devastating than the financial strains of damage and loss of home, business or personal property.
2Children, senior citizens, people with access or functional needs, and people for whom English is not their first language are especially at risk. Children may become afraid and some elderly people may seem disoriented at first. People with access or functional needs may require additional assistance.
[...]
3Everyone who sees or experiences a disaster is affected by it in some way.
4It is normal to feel anxious about your own safety and that of your family and close friends.
5Profound sadness, grief and anger are normal reactions to an abnormal event.
6Acknowledging your feelings helps you recover.
7Focusing on your strengths and abilities helps you heal.
8Accepting help from community programs and resources is healthy.
9Everyone has different needs and different ways of coping.
[...]
10The following are ways to ease disaster-related stress:
11Talk with someone about your feelings - anger, sorrow and other emotions - even though it may be difficult.
12Seek help from professional counselors who deal with post-disaster stress.
13Do not hold yourself responsible for the disastrous event or be frustrated because you feel you cannot help directly in the rescue work.
14Take steps to promote your own physical and emotional healing by healthy eating, rest, exercise, relaxation and meditation.
15Maintain a normal family and daily routine, limiting demanding responsibilities on yourself and your family.
16Spend time with family and friends.

Task: make a two-column table with the headings Domestic and Global. Under each, write one issue from the sources, the psychological knowledge applied to it, one quotation with its source and paragraph number, and the kind of evidence (case reports, argument, guidance, research agenda or experiment). Finish with one sentence on what a psychologist would need to test next.
Closure5-10 minutes
Exit ticket: "Go back to your Warm-Up sticky note. Name one psychological claim that could help with your problem, one way to test it, and one reason the result might change in another country."
Teacher notes: Sources 1 and 2 contain views now considered outdated, flagged where they appear; keep the sources' words as printed and discuss them as evidence of their time. Source 3 is about the feelings that follow a disaster. Some students may have lived through one; keep the discussion general and remind the class that anyone who feels worried or upset can talk with a trusted adult, a school counselor or a doctor. No student is asked to share a personal experience.
Differentiation Strategies
For Struggling Students
Give the four-moves table with one blank column, and have students place one sentence from each source in the right row
Pre-highlight the sentence in each source that names the issue, and have students label it D (domestic) or G (global)
Offer the frame: "Source __ applies the idea that __ to the issue of __, and its evidence is __."
For Advanced Students
Ask whether James's claim in Source 2 could be tested at all, and design on paper the smallest study that would test one part of it
Have students rewrite Source 5's conclusion so that it claims only what the invented data support
Compare the evidence in Sources 1 and 3: is a clinic's record of individual cases stronger or weaker support than public guidance with no study named?
Assessment Guidance
What to Look For
Strong answers name a specific psychological claim, not just "psychology helps"; say whether the issue is domestic, global or both, and why; quote the source with a paragraph number; name the kind of evidence behind the application; and point out what would need testing before the application is used in a new place. Watch for students who treat an argument (Source 2) or guidance (Source 3) as a tested result, and for students who repeat outdated labels from Sources 1 and 2 without flagging them.

Classroom Activities
3 Activities
1
Issue Sort: Domestic, Global or Both
15 minGroups of 3
Each group gets 8 Issue Cards (invented cases written for this page) and a sheet with three columns: Domestic, Global and Both. For each card, the group places it, writes one psychological question the issue raises, and names one application that psychological science could offer.
The 8 Issue Cards
In one U.S. state, many high school students miss so many days that they fall behind.
Residents of a U.S. coastal county often stay home when officials ask them to leave before a storm.
A town's tap water now passes every test, but many residents still refuse to drink it after a scare years ago.
Aid groups from five countries help families after an earthquake that struck near a border.
Two neighboring countries with a long history of conflict start a summer camp for teenagers from both sides.
A health message about a new vaccine must be translated and tested in dozens of countries.
Older adults who live alone in a large U.S. city report feeling lonely.
A video app used in many countries adds a reminder that pops up after midnight.
Debrief Questions
Which card was hardest to place, and what decided it?
Pick a card you placed as Domestic. What would change if the same issue were treated as a global one?
Which application would need the most testing before it was used in another country, and why?
Teacher Note
Suggested placements: cards 1, 2, 3 and 7 domestic; cards 4, 5 and 6 global; card 8 both, since one company's choice reaches users in many countries. Accept other placements with reasons: card 7 is domestic as written, but loneliness among older adults is reported in many countries. Sample questions: card 2, "What makes people judge a warning as not meant for them?"; card 5, "Does meeting people from the other side change how teens see the whole group?" These are questions to test, not settled answers.

Source Jigsaw: Four Applications, Four Kinds of Evidence
20 min4 expert groups, then mixed groups of 4
Each expert group takes one of Sources 1-4 and completes the Source Jigsaw organizer. Students then regroup so that every new group has one expert per source, and each expert teaches the others in 2 minutes.
Source Jigsaw Organizer
Who wrote the source, when, and for whom?
The issue, and whether it is domestic, global or both
The psychological knowledge being applied
One quotation, with its paragraph number
The kind of evidence: case reports, argument, guidance, research agenda or experiment
Any view in the source that is now outdated, and how it would be put today
Teacher Note
Expected outcome: the four sources rank differently on evidence and usefulness. Source 1 rests on case records, Source 2 on argument, Source 3 on guidance without a cited study, and Source 4 on a plan for future research. No source among the four reports a controlled test; push experts to say what test their source would need next.

Pilot Test Plan on Paper
15 minPairs
Pairs choose one Issue Card from Activity 1 and write, on paper only, a plan for a small test of one application. They do not run the test or contact anyone.
Pilot Test Plan Template
The issue and the people it affects
The psychological claim behind the application (one sentence)
The application: what people will receive or do
The comparison group, and how people are assigned to it
What is measured, and how to avoid relying only on what people say
Ethics: consent, privacy and how no one is harmed or left out
Adapting: one thing to change and test again before using the plan in another country
Variation
Give two pairs the same card, one planning a domestic test and one planning a test in several countries. The pairs then compare: which steps had to change, and which stayed the same?

Diagram 1: Four Moves From Claim to Application
The four moves from the Direct Instruction table, each shown with a domestic example (the invented disaster-plan study, Source 5) and a global example (the NIMH research program, Source 4). Adapting a practice for a new place means going back to the Test move there.
Diagram 2: The Invented Worksheet Study
Invented data from Source 5: 27 of 150 households in Group A (18%) and 45 of 150 in Group B (30%) said they had a written plan. Both percents use the whole group, so households that could not be reached count as no. Bar heights are drawn to scale.

Homework Assignment
~30 min
Homework: Applying Psychology at Home and Abroad
Directions: Part 1 uses Sources 1, 2 and 5. Quote every source you use with its paragraph number. Part 2 asks you to apply the sources to new situations and to plan on paper only: do not run any study, survey or program, and do not contact anyone.
Part 1: Reading the Evidence (Problems 1-3)
Source 1, paragraph 3 says that "the streets" and other places are "a larger laboratory of psychology." Explain what Witmer means, and name one domestic issue today, other than schooling, that a psychologist could study in such a "laboratory."
In Source 2, paragraph 2, James says his plan would even out an injustice. Quote the injustice he describes. Then identify one phrase in the same paragraph, other than the two outdated views already flagged before the source (how "the women would value them" and nature treated as an enemy), that reflects a view now considered outdated, and explain why.
In Source 5, compute the percent of reached households that answered yes in each group (leave out the households that could not be reached). Show your work. Then explain why these percents differ from the ones in Diagram 2, and which comparison you would report.
Part 2: Applying and Planning (Problems 4-6)
Source 3, paragraph 13 advises, "Do not hold yourself responsible for the disastrous event." Explain the psychological reasoning behind this advice, and describe how a researcher could test, on paper only, whether hearing it helps people after a disaster.
Source 4, paragraph 2 says NIMH-supported research works by "harnessing diverse, real-world data." Choose one Issue Card from Activity 1 and one application for it, then explain two ways its results might differ in another country, and what would need to be tested again.
Invented case: a city plans a campaign to get residents to check on older neighbors during heat waves. In one paragraph, explain which psychological knowledge the campaign applies, whether the issue is domestic, global or both, and how the city could find out whether the campaign works, with one ethical safeguard.

0 of 20 answered · 0 correct
Question 1 of 20 · Multiple Choice
In Source 1, paragraph 1, who brought the children to Witmer's laboratory?
Answer: C
Paragraph 1 says the children "have been brought to the laboratory by parents or teachers." B confuses the juvenile court, which paragraph 3 names as a place to study, with the people who brought the children. A and D are not in the source.
Question 2 of 20 · Multiple Choice
According to Source 1, paragraph 2, what does the combined medical and psychological examination produce?
Answer: A
Paragraph 2 says the result is "a diagnosis of the child's mental and physical condition and the recommendation of appropriate medical and pedagogical treatment." B assumes the clinic compared children; the source describes each child's case. C and D are not mentioned.
Question 3 of 20 · Multiple Choice
Besides medicine, which two fields does Witmer say clinical psychology is "quite as closely related to" in Source 1, paragraph 3?
Answer: B
Paragraph 3 says clinical psychology "is quite as closely related to sociology and to pedagogy" (pedagogy is the study of teaching). C picks up the juvenile court in the next sentence, but a court is named as a place to study, not as a field. A and D are not in the passage.
Question 4 of 20 · Multiple Choice
In Source 1, paragraph 3, why does Witmer say material for scientific study "fails to be utilized"?
Answer: D
Witmer gives two reasons: "the interest of psychologists is elsewhere engaged, and those in constant touch with the actual phenomena do not possess the training necessary." A and B invent barriers the source does not mention; C is not in the passage.
Question 5 of 20 · Multiple Choice
In Source 2, paragraph 1, what does James say grasps the individual "as in a vise"?
Answer: B
James writes, "What the whole community comes to believe in grasps the individual as in a vise." This is a claim about social influence: shared beliefs press on each person. A reads "fend off subjection" earlier in the paragraph as the answer, but that phrase describes why people accept war, not what grips them. C and D are not in the paragraph.
Question 6 of 20 · Multiple Choice
In Source 2, paragraph 2, what does James expect the drafted youths to bring back into society?
Answer: A
James says they would "come back into society with healthier sympathies and soberer ideas." C is the opposite of his aim, which is to replace war with other hard work. B misreads the list of jobs as a source of wealth; D is not in the source.
Question 7 of 20 · Multiple Choice
In Source 2, paragraph 1, which feeling does James say "Individuals, daily more numerous, now feel"?
Answer: C
James writes, "Individuals, daily more numerous, now feel this civic passion." A is a phrase from the same paragraph, but James calls the "morals of military honor" the old system that civic honor would replace. B and D are not in the paragraph.
Question 8 of 20 · Multiple Choice
Which group does Source 3, paragraph 2 NOT name as especially at risk after a disaster?
Answer: B
Paragraph 2 names "Children, senior citizens, people with access or functional needs, and people for whom English is not their first language." First responders are not in the list. A, C and D are all named, so choosing one of them misses the word NOT.
Question 9 of 20 · Multiple Choice
Which line in Source 3 applies the idea that support from other people helps recovery?
Answer: D
Paragraph 16 advises, "Spend time with family and friends," which applies social support. A (paragraph 7) is about a person's own strengths, B (paragraph 13) is about self-blame, and C (paragraph 14) is about caring for one's own body and mind; none names other people.
Question 10 of 20 · Multiple Choice
According to Source 4, paragraph 1, what does NIMH say research in "various global contexts" helps do?
Answer: A
Paragraph 1 says the research generates insights that "inform efforts to improve mental health outcomes in the United States." Paragraph 2 adds "and abroad," so the work serves a global issue and a domestic one. B overstates: the research adds to U.S. work, it does not replace it. C and D are not in the source.
Question 11 of 20 · Multiple Choice
In Source 5, what percent of all 300 households could not be reached?
Answer: B
15 + 30 = 45 households could not be reached, and 45 / 300 = 0.15, or 15%. A divides Group A's 15 by its 150 households only; C divides Group B's 30 by its 150 only; D reads the count of 45 households as a percent.
Question 12 of 20 · Multiple Choice
Suppose all 30 unreached households in Group B of Source 5 really did have a written plan. What percent of Group B's 150 households would then have a plan?
Answer: C
45 + 30 = 75 households, and 75 / 150 = 0.50, or 50%. The question shows how much the counting rule in paragraph 3 can matter. A keeps the original 45 / 150; B computes only the unreached share, 30 / 150; D reads the count of 75 households as a percent.
Question 13 of 20 · Multiple Choice
Which conclusion do the invented data in Source 5 best support?
Answer: D
The data show only that, in one county, 45 of 150 worksheet households said yes against 27 of 150 flyer households. A is the office's own conclusion in paragraph 4, which goes beyond one county. B assumes plans protect people, which the study did not measure. C ignores the 105 Group B households that did not answer yes.
Question 14 of 20 · Multiple Choice
Which of these is best described as a global issue rather than a domestic one?
Answer: C
Refugees who flee war cross borders, and the agencies come from many nations, so the issue is global. A, B and D each happen inside one district, state or city, so as written they are domestic, even though similar problems exist in other countries.
Question 15 of 20 · Short Answer
Sources 1 and 3 both apply psychology to domestic issues. Compare them: whom does each try to help, at what scale, and what kind of evidence stands behind each?
Model answer: Source 1 helps one child at a time: "Children from the public schools of Philadelphia and adjacent cities" (paragraph 1) are examined and given a treatment plan, so the scale is individual and the evidence is the clinic's case records. Source 3 speaks to everyone after a disaster, "Disasters are upsetting experiences for everyone involved" (paragraph 1), so the scale is the whole public, and its evidence is guidance from a federal agency with no study named. Rubric: 1 point for the people and scale of each source; 1 point for the kind of evidence of each; 1 point for quotations with paragraph numbers.
Question 16 of 20 · Short Answer
In Source 2, paragraph 1, James suggests that pride in civic work could grow "with time and education and suggestion enough." Describe one small study, on paper only, that could test a part of this claim, and explain what your study could not show.
Model answer: A part that could be tested is whether a short message about civic achievements raises pride in one's community. On paper, a researcher could randomly assign volunteers to read either a passage about a town's volunteer projects or a neutral passage, then measure community pride on a short rating scale, with consent and no deception. Such a study tests a small piece; it cannot show that civic pride would replace war. Rubric: 1 point for a testable variable and measure; 1 point for a comparison group and an ethical safeguard; 1 point for a limit of the study.
Question 17 of 20 · Short Answer
Source 3 was written for people in the United States. A health agency in another country wants to give the same advice to its own residents. Name two lines of Source 3 that might not fit as written, explain why, and say what the agency should check first. Use Source 4 in your answer.
Model answer: "Accepting help from community programs and resources is healthy" (paragraph 8) assumes such programs exist and are trusted; in some places help comes mainly from family or religious leaders. "Seek help from professional counselors who deal with post-disaster stress" (paragraph 12) assumes counselors are available and that seeing one carries no shame, which differs between communities. Before using the advice, the agency should ask residents how they cope and what help they can reach, then test the adapted message. Source 4 calls for fitting interventions to "the unique needs of communities and settings" (paragraph 5). Rubric: 1 point for each line with a reason; 1 point for checking or testing first, linked to Source 4.
Question 18 of 20 · Short Answer
Source 3 says, "Everyone who sees or experiences a disaster is affected by it in some way" (paragraph 3) and "Everyone has different needs and different ways of coping" (paragraph 9). Explain how these two sentences work together in a public message, and why a message that included only one of them would be weaker.
Model answer: The first sentence tells readers that being affected is normal, so a person who is struggling is not singled out as weak or strange. The second tells them that there is no single right way to react, so a person who copes differently from others need not worry that something is wrong. With only the first, readers might expect everyone to react alike; with only the second, readers might think that people who are unaffected are the norm. Together they apply psychological knowledge in a way that does not stigmatize anyone. Rubric: 1 point for the role of each sentence; 1 point for explaining the weakness of using one alone.
Question 19 of 20 · Short Answer
Source 4, paragraph 4 lists research on "Biological, psychological, and social determinants of mental health." Give one example of each kind of determinant (factor), and explain why studying them in many countries helps address a global issue.
Model answer: A biological determinant could be a person's sleep or a physical illness; a psychological one, how a person thinks about stressful events; a social one, support from family or the stress of losing a home. Their strength and their mix can differ from country to country, so research in many settings shows which factors are shared and which depend on the setting. That tells program designers what can travel across borders and what must be adapted. Rubric: 1 point for three correct examples; 1 point for explaining the value of research across countries.
Question 20 of 20 · Short Answer
Choose one domestic issue and one global issue from this page's sources. For each, describe one way psychological science can address it, the kind of evidence behind that way, and one limit.
Model answer: Domestic: children falling behind in Philadelphia schools (Source 1). The application is a clinic that examines each child and recommends treatment; the evidence is case records; a limit is that cases followed by one clinic cannot show what works for most children. Global: improving mental health in "various global contexts" (Source 4, paragraph 1). The application is research that adapts interventions to each setting; the evidence is a research plan, not yet results; a limit is that a program shown to work in one country must be tested again in the next. Rubric: 1 point for each issue correctly placed; 1 point for each application with its evidence; 1 point for the limits.

Frequently Asked Questions
10 Questions
What does D2.Psy.21.9-12 mean?
D2.Psy.21.9-12 asks high school students to discuss ways in which the applications of psychological science can address domestic and global issues. It is an indicator in the C3 Framework's psychology companion (Appendix B), in the group on applications of psychological knowledge. Students should be able to explain how a finding about behavior or mental processes becomes a practice, and what it takes to test that practice at home and abroad.
What is the difference between a domestic and a global issue?
A domestic issue is a problem inside one country; a global issue crosses borders or is shared by many countries. Many issues are both. On this page, disaster preparedness in one county is treated as domestic, and NIMH's research in "various global contexts" as global.
Does D2.Psy.21.9-12 require students to solve a real problem?
No. The verb is "discuss": students explain and evaluate ways psychological science can help. On this page every plan stays on paper; students do not run studies, survey anyone or contact officials.
Why use sources from 1907 and 1910 for a lesson about current issues?
They show that applying psychology to public problems is not new, and they let students compare older reasoning with current federal sources. Witmer's clinic applied psychology to schoolchildren, and James applied ideas about motives and social pressure to war. Both sources also contain views now considered outdated, which the page flags where they appear.
Is the study in Source 5 real?
No. The disaster-plan worksheet study, the county and every number in it are invented for this page, and the page labels them as invented. The study is there so students can practice reading a test of an application, including a weak conclusion at the end.
How is psychological science different from common-sense advice?
Psychological science tests its claims. Advice can be wise and still untested, so a careful reader asks what evidence stands behind each application: case records, an argument, official guidance, a research plan or a controlled study. The Source Jigsaw in Activity 2 practices exactly this question.
How should teachers handle the disaster reading if students have lived through one?
Keep the discussion general and never ask students to share personal experiences. Remind the class that anyone who feels worried or upset can talk with a trusted adult, a school counselor or a doctor. The Ready.gov text itself treats strong feelings after a disaster as normal, not as a sign of weakness.
Is this lesson about mental illness?
Only in part. One source describes research to improve mental health care in many countries, and another gives coping guidance after disasters. The lesson does not teach diagnosis; it asks how research and guidance reach people and how they are checked.
How does D2.Psy.21.9-12 connect to the other application indicators?
It sits in a group of related indicators. All six are in the C3 psychology group on applications of psychological knowledge, which runs from D2.Psy.18.9-12 to D2.Psy.23.9-12. D2.Psy.21.9-12 looks outward at domestic and global issues; D2.Psy.22.9-12 applies psychology to healthy lifestyle choices; D2.Psy.23.9-12 applies it to civic engagement. D2.Psy.20.9-12, on ethical solutions to actual problems, is a close parallel.
Why must a program be tested again in another country?
Because people, resources and customs differ, a program that worked in one place is only a hypothesis in the next. Source 4 names this step when it describes "adapting evidence-based interventions" to each community, and Activity 3 asks students to plan one change to retest.
