D2.Psy.7.9-12: Multicultural and Global Perspectives on Human Behavior
In plain English: D2.Psy.7.9-12 is the C3 Framework psychology indicator for grades 9-12 that asks students to explore multicultural and global perspectives that recognize how diversity is important to explaining human behavior. Students examine how culture shapes behavior, why the people studied limit what a theory explains, and how to compare groups without ranking or stereotyping. It is usually taught in high school psychology.
Explore multicultural and global perspectives that recognize how diversity is important to explaining human behavior.

D2.Psy.7.9-12 asks students to explore multicultural and global perspectives that recognize how diversity is important to explaining human behavior. A multicultural perspective looks at the many cultural groups within one society; a global perspective compares and connects people across countries and world regions. Both matter for explanation: if a theory is built on one group, it may describe that group's habits rather than human behavior in general, and an observer who judges others by home standards can mistake a cultural difference for a deficit.
Students read Wilhelm Wundt, who argued in 1912 that language, custom and myth are products of communities that individual psychology cannot explain alone, and then a paragraph in which Wundt ranks cultures in stages, a view this page labels outdated. Franz Boas (1911) shows how an outside observer's standard distorts judgments of other people's behavior. A federal law on including women and members of minority groups in NIH clinical research illustrates how the question of who is studied became a research rule. An invented two-community memory study with invented data lets students see culture shaping what people remember, not how well they remember.
Learning Objectives
By the end of this lesson, students will be able to:
Distinguish a multicultural perspective from a global perspective and give an example of each
Explain how culture can shape thought and behavior, using Wundt's and Boas's arguments as evidence
Identify ethnocentrism and outdated rankings of cultures in historical sources and explain why they are rejected
Explain why the diversity of a research sample affects how far a finding can be generalized
Analyze invented cross-cultural data and separate differences between groups from variation within groups
Prior Knowledge Required
Students should already be comfortable with:
Samples, generalization and replication in psychological research D2.Psy.1.9-12
Validity of measurements, including construct and external validity D2.Psy.5.9-12
Computing a mean, a median and a range from a small data set
"Write down one thing that is polite in your family or community and might seem odd, or even rude, somewhere else. Then write how an outsider might misread it."
Collect a few examples without names. Common answers involve greetings, eye contact, how loudly people speak, whether to arrive exactly on time, and whether children speak up to adults. Ask: if a psychologist from outside watched this behavior and explained it, what could go wrong? Keep the answers: they lead straight into Boas's traveller in Source 3.

Who psychology has studied. The psychologist Jeffrey Arnett analyzed the articles in six leading journals of the American Psychological Association and found that their authors, samples and editors were predominantly American, although Americans make up less than 5% of the world's population (J. J. Arnett, "The Neglected 95%: Why American Psychology Needs to Become Less American," American Psychologist 63, 2008). Joseph Henrich, Steven Heine and Ara Norenzayan later used the label WEIRD for samples drawn from Western, educated, industrialized, rich and democratic societies, and argued that such samples are often unusual rather than typical of people worldwide (Behavioral and Brain Sciences, 2010). Diagram 2 shows the gap. A finding from such samples may still hold elsewhere, but that has to be tested, not assumed.
Two early voices. Wilhelm Wundt, whose laboratory and classrooms at Leipzig trained many early psychologists (as his translator notes in the 1916 preface), also spent years on what he called Völkerpsychologie, "folk psychology": the study of mental life as it appears in a community's language, myths and customs. In Source 1, "its problem" means the subject matter of folk psychology. Franz Boas, an anthropologist whose 1911 book discusses many peoples of the Americas, among them the Inuit and the Kwakiutl (today usually called Kwakwaka'wakw) of Vancouver Island, wrote Source 3.
1[...] All phenomena with which mental sciences deal are, indeed, creations of the social community. Language, for example, is not the accidental discovery of an individual; it is the product of peoples, and, generally speaking, there are as many different languages as there are originally distinct peoples. The same is true of the beginnings of art, of mythology, and of custom. [...] Its problem relates to those mental products which are created by a community of human life and are, therefore, inexplicable in terms merely of individual consciousness, since they presuppose the reciprocal action of many. This will be for us the criterion of that which belongs to the consideration of folk psychology. A language can never be created by an individual. [...] Thus, then, in the analysis of the higher mental processes, folk psychology is an indispensable supplement to the psychology of individual consciousness. Indeed, in the case of some questions the latter already finds itself obliged to fall back on the principles of folk psychology. [...]

1It is an impression obtained by many travellers, and also based upon experiences gained in our own country, that primitive man of all races, and the less educated of our own race, have in common a lack of control of emotions, that they give way more readily to an impulse than civilized man and the highly educated. I believe that this conception is based largely upon the neglect to consider the occasions on which a strong control of impulses is demanded in various forms of society.
2Most of the proofs for this alleged peculiarity are based on the fickleness and uncertainty of the disposition of primitive man, and on the strength of his passions aroused by seemingly trifling causes. I will say right here that the traveller or student measures the fickleness of the people by the importance which he attributes to the actions or purposes in which they do not persevere, and he weighs the impulse for outbursts of passion by his standard. Let me give an example. A traveller desirous of reaching his goal as soon as possible engages men to start on a journey at a certain time. To him time is exceedingly valuable. But what is time to primitive man, who does not feel the compulsion of completing a definite work at a definite time? While the traveller is fuming and raging over the delay, his men keep up their merry chatter and laughter, and cannot be induced to exert themselves except to please their master. Would not they be right in stigmatizing many a traveller for his impulsiveness and lack of control when irritated by a trifling cause like loss of time? Instead of this, the traveller complains of the fickleness of the natives, who quickly lose interest in the objects which the traveller has at heart.
3[...] More generally speaking, when we want to give a true estimate of the power of primitive man to control impulses, we must not compare the control required on certain occasions among ourselves with the control exerted by primitive man on the same occasions. If, for instance, our social etiquette forbids the expression of feelings of personal discomfort and of anxiety, we must remember that personal etiquette among primitive men may not require any inhibition of the same kind. We must rather look for those occasions on which inhibition is required by the customs of primitive man. [...]
[...]
4I think these considerations illustrate that the differences between civilized man and primitive man are in many cases more apparent than real; that the social conditions, on account of their peculiar characteristics, easily convey the impression that the mind of primitive man acts in a way quite different from ours, while in reality the fundamental traits of the mind are the same.

Multicultural or global?
Classify two invented studies: (a) interviews with students whose families speak 14 different home languages, all at one high school; (b) the same memory task given to adults in Ghana, Peru and Vietnam.
Result: (a) Multicultural: it looks at diversity within one society, here one school. (b) Global: it compares people across countries and world regions. Many questions need both, for example comparing groups within each of several countries.
Weighing the evidence: Source 3, paragraph 1
What evidence does Boas say the "impression" about self-control rests on, and why is it weak?
Result: It comes from what "many travellers" report and from "experiences gained in our own country": casual observations by outsiders, not systematic measurement. Boas adds that the impression ignores "the occasions on which a strong control of impulses is demanded in various forms of society," so the observers never looked where control actually matters to the people they judged.
Who was studied? (Arnett, 2008)
Arnett reports that the samples in six leading APA journals were predominantly American, while Americans make up less than 5% of the world's population. If just over half of the participants were American, at least how over-represented were Americans?
Result: More than 50 / 5 = 10: Americans supplied more than 10 times the share of participants that their share of the world's people would predict. The more than 95% of humanity outside the United States supplied less than half of the participants. Findings from such samples need testing in other places before they can be called general.
Within-group variation and between-group differences
Two invented classes take a reaction-time test. Class X averages 310 milliseconds and Class Y 320, but scores in each class run from 250 to 390. Can you predict one student's score from the class he is in?
Result: No. The between-group difference is 10 milliseconds, while each class spans 390 - 250 = 140 milliseconds, 14 times as wide. Many students in the slower class beat many in the faster one. Using a group average to judge an individual is how stereotypes form.
Same behavior, different meanings (invented scenario)
A visiting teacher notices that a new student looks down while being corrected and decides the student is not paying attention. Suppose that in the student's family, looking down while an adult speaks is taught as a sign of respect. How should a researcher studying classroom attention handle this?
Result: Ask what the behavior means within the student's own community before coding it. An observation code such as "eye contact = attention" would measure the observer's culture, not the student's attention: a validity problem caused by ignoring diversity.
Close the segment by asking which of the other examples could be studied from a multicultural angle, a global angle, or both.
Guided Practice15 minutes
Read Source 5 together. It is an invented study with invented data, and a small sample: 6 volunteers from each of two communities. The communities are left unnamed on purpose, so that the data are not read as a claim about any real place.
1Invented study summary, written for this page. A team of researchers from two countries worked together on a memory study. They recruited 12 adult volunteers: 6 from Community A, a farming town in one country, and 6 from Community B, a large city in another country. Everyone gave written consent in their own language, and the materials were translated and then translated back by a second person to check the meaning.
2Each volunteer read two short stories of the same length, in their own language. Story 1 described a harvest festival of the kind held every year in Community A. Story 2 described a city New Year celebration of the kind held every year in Community B. Half of the volunteers in each community read Story 1 first and half read Story 2 first. One day later, each volunteer wrote down everything they remembered, and two scorers who did not know which community a volunteer came from counted the correct details, out of 20 possible.
3Details recalled, with each community's volunteers listed in the same order in both of its lists. Community A, Story 1: 15, 12, 14, 16, 11, 13. Community A, Story 2: 9, 11, 8, 12, 10, 10. Community B, Story 1: 10, 8, 11, 9, 12, 7. Community B, Story 2: 13, 15, 11, 14, 12, 12.
4The scorers also counted "changes": details that a volunteer reported differently from the story, usually in a way that matched customs at home. Community A volunteers made 4 changes in total on Story 1 and 17 on Story 2. Community B volunteers made 15 changes on Story 1 and 5 on Story 2.
5The team's note: "With 6 volunteers from each community, these results describe these 12 people. They do not show that everyone from either place remembers this way."
SVHS (invented scenario), Source 5: Remembering stories from home and from elsewhere (invented scenario with invented data) (2026). Original passage written for this page.
Design. Every volunteer read both stories, so each person is compared with themselves. The order was counterbalanced, the materials were back-translated, and the scorers did not know each volunteer's community.
Community A. Story 1: (15 + 12 + 14 + 16 + 11 + 13) / 6 = 81 / 6 = 13.5 details. Story 2: (9 + 11 + 8 + 12 + 10 + 10) / 6 = 60 / 6 = 10 details. Community A recalled 3.5 more details, on average, from the festival of its own kind.
Your turn. Pairs compute Community B's two means and decide whether B shows the same pattern; the numbers return in the quiz and homework.
Check each person. In Community A, every volunteer recalled more from Story 1, by 1 to 6 details. A group average can hide individuals who differ from it, so ask pairs to check Community B person by person.
Independent Practice15 minutes
Students read Sources 2 and 4 on their own and use them, with Sources 1, 3 and 5, for the quiz and homework.
Outdated source, read with care: in Source 2, Wundt arranges cultures in a single line of "stages," from what he calls "the lowest grade of culture" to more "advanced" ones, and compares the history of peoples to a person growing from childhood to adulthood. This ranking is outdated and rejected in psychology today. The page prints it so that students can identify the assumption and explain, in the quiz and homework, what is wrong with it; it is not a finding.
Source 4 is a federal law, added by Public Law 103-43 in 1993 (the NIH Revitalization Act), that governs who is included in clinical research funded by the National Institutes of Health. It is printed here for what it shows about research samples.
1But there is also a second path of investigation, and it is this which the present work adopts. It consists--to retain the image used above--in taking transverse instead of longitudinal sections, that is, in regarding the main stages of the development with which folk psychology is concerned in their sequence, and each in the total interconnection of its phenomena. Our first task, then, would be the investigation of primitive man. We must seek a psychological explanation of the thought, belief, and action of primitive man on the basis of the facts supplied by ethnology. As we proceed to more advanced stages, difficulties may, of course, arise with regard to the delimitation of the various periods; indeed, it will scarcely be possible to avoid a certain arbitrariness, inasmuch as the processes are continuous. The life of the individual person also does not fall into sharply distinct periods. Just as childhood, youth, and manhood are stages in a continuous growth, so also are the various eras in the development of peoples. Yet there are certain ideas, emotions, and springs of action about which the various phenomena group themselves. It is these that we must single out if the content of folk psychology is to be classified, with any measure of satisfaction, according to periods. Moreover, it should be particularly noticed that, in starting our discussion with primitive man, as we naturally must, the term 'primitive' is to be taken relatively, as representing the lowest grade of culture, particularly of mental culture. There is no specific ethnological characteristic that distinguishes this primitive stage from those that are more advanced; it is only by reference to a number of psychological traits, such as are indicative of the typically original, that we may determine that which is primitive. Bearing in mind this fact, we must first describe the external traits of primitive culture, and then consider the psychological factors of primitive life.

Task: in a short paragraph, explain what Source 2 assumes about how cultures should be compared, and what Source 3 would say about that assumption.
Closure5-10 minutes
Exit ticket: "Name one way that studying only one kind of person could lead psychology to a wrong explanation of behavior."
Teacher note on language: Sources 2 and 3 use terms such as "primitive man" and "civilized man," common in 1911-1921 and now outdated. Quote them only inside quotation marks, and use "community," "society" or the group's own name in discussion. Boas argued against ranking, yet his 1911 book also speculates, right after the last paragraph printed in Source 3, about brain differences between races; later research does not support that speculation, and it is not part of this lesson.
Teacher note on discussion: keep examples about the class's own communities voluntary and anonymous, and steer away from claims about any real group's traits. The point of the lesson is that individuals vary widely within every group.
Differentiation Strategies
For Struggling Students
Give a three-column organizer for each source: who wrote it and when, what it says about culture, and whether the claim is current or outdated
Pre-mark in Source 3 the sentence where Boas names the traveller's mistake
Provide the Source 5 data as a table with sums already filled in
For Advanced Students
Compare Wundt's two aims in Sources 1 and 2: which one still guides cultural psychology, and which one was dropped?
Explain why back-translation in Source 5 protects validity, and what it cannot fix
Design, on paper, a fourth row for the Source 5 table: a third community and a third story, with a prediction
Assessment Guidance
What to Look For
Strong answers separate the two perspectives (within one society, across societies), quote sources with paragraph numbers, label the ranking in Source 2 as outdated with a reason, and use the Source 5 data to show both a between-group pattern and the variation within each group. Watch for answers that turn a group average into a statement about every member of the group.

1
Whose Standard? Six Behaviors, Two Readings
15 minGroups of 3
Each group gets 6 invented scenario cards. Each card gives a behavior and an outsider's interpretation. The group writes a second interpretation from inside the person's own setting, then says how a researcher could find out which reading is right, as Boas recommends in Source 3, paragraph 3.
The 6 Scenario Cards (invented)
A student does not raise her hand in class discussion. Outsider's reading: she is not interested.
A family arrives an hour after the time on a party invitation. Outsider's reading: they are rude.
A boy answers his grandmother's questions in very few words. Outsider's reading: he is shy.
Shoppers at a market bargain loudly over prices. Outsider's reading: they are angry.
A new employee waits to be asked before giving an opinion in a meeting. Outsider's reading: she has no ideas.
A teenager spends every weekend helping at a family business. Outsider's reading: his parents are too strict.
Debrief Questions
For which card would a questionnaire written in one culture most likely mismeasure people from another? Why?
Boas says to look at "those occasions on which inhibition is required by the customs" of a group. Rewrite that advice for card 1.
Teacher Note
Accept any inside reading that is plausible and respectful, and push groups to name a way to check it, such as asking members of the community what the behavior means, observing the same person in several settings, or comparing behavior on occasions that matter equally to both groups. Keep the cards anonymous: they describe invented people, not real groups.

Sample Audit: Who Is in the Data?
15 minPairs
Pairs audit an invented issue of a psychology journal with 8 studies and decide how far its findings can be generalized.
The Invented Journal Issue
Study 1: 120 university students, United States. Study 2: 85 adults online, United States. Study 3: 200 high school students, Germany. Study 4: 60 university students, United States. Study 5: 150 adults, Japan. Study 6: 90 university students, United Kingdom. Study 7: 75 children, United States. Study 8: 220 adults, Nigeria.
Tasks
Find the total number of participants and the percent from the United States.
Find the percent from Western industrialized countries in this issue (count the United States, Germany and the United Kingdom).
Which two studies would you most want to see replicated in other regions before calling their results general? Explain.
Answer Key
Total: 120 + 85 + 200 + 60 + 150 + 90 + 75 + 220 = 1,000. United States: 120 + 85 + 60 + 75 = 340, or 34%. Western industrialized: 340 + 200 + 90 = 630, or 63%. Task 3 has no single answer; strong answers name a study whose sample is narrow (for example, Study 4, 60 students at one kind of institution) and a region missing from the issue.

Lost in Translation: Rewriting Five Questionnaire Items
20 minPairs
A questionnaire item can carry its culture with it. Pairs read 5 invented items from a "social life" questionnaire, name the assumption hidden in each, and rewrite the item so it could work in many communities. The questionnaire is not given to anyone.
The 5 Items (invented)
"I often go to parties on Friday nights."
"I would rather decide things for myself than ask my family."
"I feel comfortable disagreeing with my teacher in front of the class."
"I spend a lot of time on my own hobbies."
"I have my own bedroom where I can be alone."
Questions for Each Item
What does the item assume about free time, family, school or money?
Could two people with the same trait answer differently because of where they live?
How would you check, before a real study, that the rewritten item means the same thing in another language?
Variation for Advanced Students
Pick one item and describe a back-translation check like the one in Source 5, paragraph 1, plus one more check that back-translation alone would miss.

Each dot is one invented volunteer's score on one story; stacked dots share a score. Every volunteer appears once in each of their community's two rows. Invented data, 6 volunteers per community: a small sample.
Diagram 2: Who Psychology Studied (Arnett, 2008)
Arnett (2008) found that the samples in six leading American Psychological Association journals were predominantly American, although Americans make up less than 5% of the world's population (J. J. Arnett, "The Neglected 95%," American Psychologist 63, 2008). The top bar is drawn at 50%, the least that "predominantly" can mean, and the bottom bar at 5%, the most that "less than 5%" allows, so the real gap is at least this wide.

Homework: Diversity in the Explanation of Behavior
Directions: Part 1 uses Sources 1-4: Sources 1 and 3 are printed in Direct Instruction, and Sources 2 and 4 in Independent Practice. Part 2 uses Source 5, an invented study with invented data printed in Guided Practice. Quote sources with paragraph numbers and show every computation. Plans are written on paper only.
Part 1: Historical and Federal Sources (Problems 1-3)
Wundt says in Source 1 that folk psychology is "an indispensable supplement to the psychology of individual consciousness." Explain his reason, and give an example of your own, other than language, of a behavior or mental product that a study of single individuals could not fully explain.
In Source 2, Wundt admits that "it will scarcely be possible to avoid a certain arbitrariness" in dividing development into periods. Explain what he means, and explain how this admission weakens his own plan to compare cultures by periods.
Source 4, paragraph 9 requires trials to be designed for "a valid analysis" of whether the variables studied affect women or members of minority groups differently. Explain why such an analysis needs enough participants from each group, using an invented example from education or psychology research.
Part 2: The Two-Community Memory Study (Problems 4-6)
Using Source 5, paragraph 3, compute each community's overall mean number of details recalled, across both stories (12 scores per community). What does comparing these two overall means show that the story-by-story means do not?
Using Source 5, paragraph 3, find the range of Community A's Story 2 scores and the difference between the two communities' mean scores on Story 2. Is any Community A volunteer's Story 2 score higher than some Community B volunteer's? Explain why a group average should not be used to predict one person.
On paper only, plan an extension of Source 5 to a third community. Explain how you would choose or write the stories, translate them, score them fairly, and what result would show that the pattern holds.

0 of 20 answered · 0 correct
Question 1 of 20 · Multiple Choice
Which invented study takes a global perspective rather than a multicultural one?
Answer: B
A global perspective compares people across countries and world regions. A, C and D each study diversity within one society, which is a multicultural perspective; D adds generations, which is still within one place.
Question 2 of 20 · Multiple Choice
In Source 1, why does Wundt say that "a language can never be created by an individual"?
Answer: C
Wundt describes the products of folk psychology as things that "presuppose the reciprocal action of many": a language exists because a community uses it together. A misreads the point as a claim about intelligence; Wundt's argument is about what a language is, not about anyone's ability.
Question 3 of 20 · Multiple Choice
What does Wundt mean in Source 1 by calling folk psychology "an indispensable supplement to the psychology of individual consciousness"?
Answer: D
A supplement adds to something rather than replacing it: for the "higher mental processes," studying single minds must be joined by studying the communities that create language, myth and custom. A turns "supplement" into "replacement." C confuses Source 1 with the stage plan in Source 2.
Question 4 of 20 · Multiple Choice
According to Source 3, paragraph 2, what is wrong with the traveller's judgment that his workers are fickle?
Answer: B
Boas says the traveller "measures the fickleness of the people by the importance which he attributes to the actions or purposes in which they do not persevere." Time matters to him in a way it does not to them. A names a limit Boas does not mention, and C invents a record-keeping error.
Question 5 of 20 · Multiple Choice
In Source 3, paragraph 2, the workers "keep up their merry chatter and laughter" while the traveller is "fuming and raging over the delay." Whom does Boas suggest could fairly be called impulsive?
Answer: C
Boas asks, "Would not they be right in stigmatizing many a traveller for his impulsiveness and lack of control when irritated by a trifling cause like loss of time?" From the workers' standpoint, the traveller is the one who cannot control himself. A repeats the traveller's own judgment. B contradicts the text, which describes the traveller fuming.
Question 6 of 20 · Multiple Choice
What is Boas's conclusion in Source 3, paragraph 4?
Answer: A
He concludes that differences are "in many cases more apparent than real" and that "in reality the fundamental traits of the mind are the same"; social conditions create the impression of difference. C is the stage view of Source 2, which Boas's argument works against. D goes beyond the text: Boas says the differences are often apparent, not that they cannot be measured.
Question 7 of 20 · Multiple Choice
Wundt writes in Source 2 that "primitive" is to be taken "as representing the lowest grade of culture." Why is this way of comparing cultures rejected today?
Answer: D
Placing cultures on one ladder from "lowest" to "advanced" treats the writer's own society as the measure of development, the same kind of outside standard Boas warns against in Source 3. A is not the problem: using evidence from many societies is still good practice. C contradicts the source, which compares the eras of peoples to the stages "childhood, youth, and manhood."
Question 8 of 20 · Multiple Choice
Source 4, paragraph 4 requires outreach programs to recruit women and members of minority groups. What problem in research does outreach address?
Answer: A
If researchers recruit only where it is convenient, some groups are left out and the sample is biased. Outreach widens who is invited. B is a reliability problem and C is a blinding problem; neither is solved by recruitment.
Question 9 of 20 · Multiple Choice
What is the purpose of the "valid analysis" required in Source 4, paragraph 9?
Answer: C
The law asks whether "the variables being studied in the trial affect women or members of minority groups ... differently than other subjects." That is a check on whether a finding generalizes. D assumes the answer in advance; the analysis exists because the effect might differ. A goes beyond the text, which sets no exact numbers.
Question 10 of 20 · Multiple Choice
According to Source 4, paragraphs 5-8, when does the inclusion requirement not apply?
Answer: C
Paragraph 6 names inclusion that "is inappropriate with respect to the health of the subjects"; paragraphs 7 and 8 add the purpose of the research and other circumstances the NIH Director designates. A and B are not reasons the law gives, and D is not mentioned.
Question 11 of 20 · Multiple Choice
Use the invented data in Source 5, paragraph 3. What is Community B's mean number of details recalled on Story 2?
Answer: D
Sum: 13 + 15 + 11 + 14 + 12 + 12 = 77, and 77 / 6 ≈ 12.8. A is the median (the middle two ordered scores are 12 and 13). B is the sum before dividing. C is Community B's mean on Story 1.
Question 12 of 20 · Multiple Choice
In Source 5, why did half of each community's volunteers read Story 1 first and half read Story 2 first?
Answer: A
Counterbalancing spreads practice and tiredness evenly over the two stories, so a difference between stories cannot come from which one was read first. C confuses a design control with a result the design is meant to test.
Question 13 of 20 · Multiple Choice
Source 5 says the materials were "translated and then translated back by a second person." Which problem does back-translation help prevent?
Answer: B
If a translation changes a detail's meaning, the two communities are no longer reading the same story, and the comparison loses validity. C is handled by blind scoring, not translation, and D is a sample-size limit that translation cannot fix.
Question 14 of 20 · Multiple Choice
Which conclusion do the invented data in Source 5 support best?
Answer: D
Each community's mean was higher for its own kind of festival, so culture shaped what was remembered. A and B read a difference in content as a difference in ability, which the data contradict: each group did better on one story. C turns a small group's average into a claim about everyone, which the team's own note rules out.
Question 15 of 20 · Short Answer
Use Source 5, paragraph 4. Compute the mean number of "changes" per volunteer for each community on each story. Describe the pattern, and explain what it suggests about how culture affects memory.
Model answer: Community A: Story 1, 4 / 6 ≈ 0.7; Story 2, 17 / 6 ≈ 2.8. Community B: Story 1, 15 / 6 = 2.5; Story 2, 5 / 6 ≈ 0.8. Each community made far more changes on the unfamiliar story, usually in the direction of customs at home. Memory is not a recording: people fill gaps and reshape details with what they already know, so the same story is remembered differently by people from different backgrounds.
Question 16 of 20 · Short Answer
An invented study of 200 university students in one country finds that people make faster choices when they are alone than in a group. Explain two reasons the finding might not hold everywhere, and describe a sample that would test it more widely.
Model answer: First, university students are younger, more educated and often wealthier than most people, so the sample may not represent even its own country. Second, how people decide in groups depends on cultural norms about consulting others, which differ across societies. A better test would repeat the study, with translated and checked materials, in several countries on different continents, including adults who are not students.
Question 17 of 20 · Short Answer
A visiting teacher (invented scenario) says that the students in a new class "do not care about learning" because they rarely ask questions in front of the class. Use Boas's method in Source 3, paragraph 3 to explain how a researcher should test the teacher's claim.
Model answer: Boas says not to compare a group's behavior with what one's own culture expects on the same occasion, but to "look for those occasions" that the group's own customs treat as important. A researcher would find out how these students show interest in their setting: asking questions privately, helping each other, working carefully on assignments. Then measure those behaviors, ideally with observers from the community, before concluding anything about caring.
Question 18 of 20 · Short Answer
Two invented groups of students take a puzzle test. Group 1 averages 52 points and Group 2 averages 55, but scores in each group run from 30 to 80. Explain what these numbers say about predicting one student's score from their group, and how this connects to stereotypes.
Model answer: The between-group difference is 55 - 52 = 3 points, while each group spans 80 - 30 = 50 points, about 17 times as wide. Knowing a student's group tells you almost nothing about that student's score: many students in Group 1 outscore many in Group 2. A stereotype makes exactly this mistake, applying a small average difference, or an imagined one, to every individual in a group.
Question 19 of 20 · Short Answer
Explain how the federal rule in Source 4 connects to the idea that diversity is important to explaining human behavior. Cite one paragraph.
Model answer: Paragraph 1 requires NIH-funded clinical research to include women and members of minority groups as subjects, and paragraph 9 requires trials to be designed for "a valid analysis" of whether the variables studied affect those groups differently. The rule assumes what this lesson argues: a result from one kind of person may not hold for others, so explaining how people respond requires studying a range of people and checking for differences.
Question 20 of 20 · Short Answer
Using two different sources from this lesson, explain why diversity is important to explaining human behavior.
Model answer: Source 3 shows that an observer who uses his own standard can mistake a cultural difference for a weakness: the traveller judged his workers by his own goals. Source 5 (invented data) shows that what people remember depends on what is familiar in their own culture, so a memory theory tested in one community could describe that community's experience rather than memory in general. Studying diverse people, and judging them by their own settings, protects explanations from both errors.

Frequently Asked Questions
10 Questions
What does D2.Psy.7.9-12 mean?
D2.Psy.7.9-12 asks high school students to explore multicultural and global perspectives that show how diversity matters for explaining human behavior. Students should be able to say how culture shapes thought and behavior, why the people a study includes limit what it can explain, and how to compare groups without ranking them or stereotyping individuals.
What is the difference between a multicultural and a global perspective?
A multicultural perspective looks at the many cultural groups within one society, such as language communities in one city. A global perspective compares and connects people across countries and world regions. Research questions often need both.
What does WEIRD mean in psychology?
It is the acronym Joseph Henrich, Steven Heine and Ara Norenzayan used in their 2010 article "The weirdest people in the world?" (Behavioral and Brain Sciences) for samples drawn from Western, educated, industrialized, rich and democratic societies. They argued that broad claims about human behavior are often based on such samples alone, and that WEIRD samples are often unusual, so how far those findings apply to people in other societies has to be checked rather than assumed.
How do I teach D2.Psy.7.9-12 without stereotyping any group?
Keep the focus on method: who was studied, how behavior was measured, and whose standard was used to judge it. Use invented or unnamed groups for data, stress that individuals vary widely within every group, and treat any comparison as a statement about averages in a particular sample. Classroom sharing about students' own communities should be voluntary and anonymous.
Why does this lesson include outdated sources?
Seeing an outdated idea in its own words helps students recognize it when it appears in newer forms. Source 2 is labeled outdated where it appears, and the page explains that its ranking of cultures is rejected today. Analyzing it next to Boas's critique shows how psychology's thinking about culture changed.
Who was Franz Boas?
Franz Boas was an anthropologist whose 1911 book, The Mind of Primitive Man, gathered lectures he gave in Boston and Mexico City in 1910-1911 on culture, language and human physical variation. The book's title and some of its terms are outdated, and parts of it reflect the science of its time, so it is read here as a historical source.
What is cross-cultural psychology?
It is the study of the same psychological question in more than one culture, with methods made equivalent across them: translated and back-translated materials, tasks that are familiar in each setting, and scorers who do not know which group a person belongs to. Its findings show which patterns are widely shared and which depend on context.
How does D2.Psy.7.9-12 connect to other C3 indicators?
It builds on the research methods indicators, especially D2.Psy.1.9-12 on scientific methods and D2.Psy.5.9-12 on validity. It leads to D2.Psy.12.9-12, on how social, cultural, gender and economic factors influence behavior around the world, and it connects to sociology indicators on culture such as D2.Soc.7.9-12.
Is there a middle school version of D2.Psy.7?
No. The C3 Framework writes its psychology indicators for grades 9-12 only. Middle school students meet related ideas in the C3 geography and history indicators on culture and perspectives.
Do students run a cross-cultural study in this lesson?
No. Students analyze historical sources, a federal law and an invented data set, and every plan they write stays on paper. A real study with people would need informed consent, review board approval and partners from each community.
