1. A public health report describes Country A as moving from stage 2 to stage 3 of the demographic transition model over the past 15 years. The report notes improved sanitation and vaccination programs, with a recent expansion of secondary education for girls and increased urban employment. Demographic transition theory predicts that death rates typically fall first, followed by declining birth rates as families shift investment toward fewer children. The ministry provides simplified population pyramids (male left, female right): Year 1 (late stage 2) 80+ || 60–79 ||| 40–59 |||| 20–39 |||||| 0–19 ||||||||| Year 15 (stage 3) 80+ ||| 60–79 |||| 40–59 ||||| 20–39 |||||| 0–19 ||||||| Based on the pyramids and the specified stage 3 transition, which trend is most likely to occur in the next decade?
2. A workplace safety team assesses associative learning. Classical conditioning is operationally defined as a change in an involuntary response when a neutral cue is repeatedly paired with a reflex-eliciting stimulus. On Day 1, a flashing blue light (NS) is followed by a brief, loud alarm (US) that produces a startle response (UR). After several days, the flashing blue light alone produces a startle response (CR). Which outcome is most consistent with classical conditioning principles if the alarm is no longer presented for several weeks?
3. A nation is classified as Stage 4 and its pyramid shows a narrow base relative to older cohorts. 80+ |||| 60-79 |||||| 40-59 ||||||| 20-39 |||||| 0-19 |||| M FBased on the population pyramid, which trend is most likely to occur if fertility remains low?
4. A genome-wide association project reports that many genetic variants each contribute small increases in risk for social anxiety symptoms. In a laboratory social-evaluation task, symptom severity varies continuously rather than clustering into distinct categories. Which interpretation best fits the biological basis of the observed social behavior?
5. A social psychology team studied how cultural norms shape attitudes toward asking instructors for help. Students from two campus cultural organizations (one emphasizing independence, one emphasizing interdependence) read the same vignette about a struggling student considering office hours. Participants rated whether seeking help is "appropriate" and "responsible." Which result is most consistent with cultural influence on attitudes?
6. A hospital system evaluated 9,500 births to study severe maternal morbidity (SMM) within 42 days postpartum. The primary social structure examined was structural racism operationalized as neighborhood-level historical redlining grade (A–D), where D indicates historically disinvested areas. SMM rates were A: 0.9%, B: 1.2%, C: 1.8%, D: 3.1%. Differences persisted after adjustment for maternal age, education, and prenatal visit count. Which scenario best illustrates the principle described (structural conditions shaping risk beyond individual-level factors)?
7. A fitness app awards a badge the first time a user logs a workout after an unpredictable amount of time has passed since the last badge (variable interval). The badge is always followed by a congratulatory message, and users can log workouts at any time. Which behavior pattern is most consistent with this reinforcement schedule?
8. In a low-income region, a new maternal health program reduces deaths during childbirth. Community leaders observe that more women survive to raise children and participate in local economic activities. Over several years, households report increased investment in each child's education and nutrition. The central demographic concept is maternal mortality and its social implications. Which downstream demographic change is most plausible over the longer term?
9. A longitudinal study interviews 15-year-olds about future plans. One participant reports trying different peer groups, electives, and part-time jobs, stating they are "testing what fits" before committing to a path. The investigators frame their interpretation using Erikson's identity vs. role confusion stage. Based on the scenario, which conclusion about identity formation is most consistent with Erikson's theory?
10. A study uses a simplified Asch-style procedure in a classroom. One real participant answers multiple-choice questions aloud after hearing four confederates respond first. On critical items, the confederates unanimously choose an incorrect option. In one condition, the participant's answer is written privately on a card and not shared; in another, the participant answers aloud. The researchers predict more incorrect matching of the group's answer in the aloud condition. Which statement is most consistent with conformity as described?
11. A researcher observes a toddler at home. The toddler watches an older sibling press a specific sequence of buttons on a music player to start a favorite song. The next day, without being prompted and without any adult providing instructions, the toddler approaches the player and presses the same button sequence to start the song. The researcher notes that the toddler had never previously succeeded at turning on the music player. Which conclusion about social learning is most consistent with this scenario?
12. In a bilingual preschool, researchers examine the Sapir-Whorf hypothesis (linguistic relativity) by comparing children who speak Language A, which uses obligatory evidential markers (e.g., suffixes distinguishing "seen" vs "heard-from-others"), to children who speak Language B, which does not grammatically mark information source. In a task, children view short clips where a character either witnesses an event or only hears about it; later they answer questions about how they know what happened. Across groups, memory for the event content is similar, but Language A speakers spontaneously volunteer the source (e.g., "I saw it") more often and are faster to reject misleading testimony about events they only heard about. Based on the vignette, which conclusion is most consistent with Sapir-Whorf?
13. A multinational company offered negotiation training after conflicts emerged between employees from Culture A (where direct disagreement in meetings is common) and Culture B (where disagreement is often communicated indirectly to preserve harmony). Some managers from Culture A interpreted indirect feedback as "dishonest" and rated Culture B employees as less competent. Culture B employees reported that direct confrontation felt disrespectful and led them to withhold input during meetings. A consultant proposed training that frames both styles as context-dependent communication strategies and teaches employees to ask clarifying questions about intent rather than assuming character flaws. Concept tested: ethnocentrism. What outcome would be most expected from an ethnocentric viewpoint among managers from Culture A?
14. An individual who defines themselves primarily by their relationships with close family and friends, prioritizing group harmony and interdependence, is likely from a culture that emphasizes:
15. A study on attraction in shared living spaces recruited first-year roommates who had not met before move-in. For the first month, some pairs were assigned to adjacent rooms on the same hallway (high incidental contact), while others were assigned to rooms in different buildings (low incidental contact). Roommates were not required to attend any events together. After one month, participants rated how much they "liked" their roommate (1–10). Ratings were higher in the high incidental contact group. Which outcome would be expected given the social context described?
16. Researchers apply a life course perspective to understand how timing of retirement interacts with social roles. In interviews, some participants describe retiring earlier than peers due to caregiving needs, while others retire later to maintain health insurance coverage. Participants report that these different timings affect their social networks and perceived status in family decision-making. Which outcome is most consistent with the life course perspective on this transition?
17. A researcher studied how a student's belief about their own study habits changes after making a public commitment. Participants predicted they would study 10 hours for an upcoming exam, then either posted the goal on a class forum (public) or wrote it privately (private). Actual study time was tracked, and participants later rated whether they are "the type of person who studies consistently." Which explanation best fits self-perception theory rather than cognitive dissonance?
18. A teacher uses a token system: a student earns a token for every 5 completed math problems (fixed ratio 5). After a week, the teacher changes the rule so the token is earned after a variable number of completed problems averaging 5 (variable ratio 5). Assuming tokens remain equally valued, what change in the student's work pattern is most likely?
19. A journalist analyzes how a local newspaper describes two groups: "refugees" and "expatriates." Both groups include people from multiple countries and social classes. The analysis finds that "refugee" stories increasingly emphasize disorder and dependency and are paired with descriptors that imply a single racial image, while "expatriate" stories emphasize entrepreneurship and cosmopolitanism without racial cues. Readers later report that they associate "refugees" with a particular race and support stricter housing restrictions for that group. Which statement best exemplifies racialization in the journalist's findings?
20. To test ELM, participants watched a short video advocating a new campus ID system. Argument quality was manipulated (clear security rationale vs vague claims). Source expertise was also manipulated (IT director vs first-year student). Participants were either distracted by a secondary task (counting tones) or not distracted. Which finding best supports peripheral-route persuasion?
