1. A qualitative study examines how adolescents describe themselves after a major move to a different region. One 16-year-old reports that they no longer know "how to act," and they feel uncertain about friendships and goals. The authors interpret this as a challenge within Erikson's identity vs. role confusion stage. Which conclusion is most consistent with Erikson's theory?
2. A sensory interaction experiment tests whether smell influences perceived sweetness. Participants drink a solution with low sugar concentration while exposed to either a vanilla odor or no added odor. They rate sweetness higher in the vanilla-odor condition, even though sugar concentration is unchanged. Which explanation best aligns with the observed taste judgments?
3. A teacher adopts an approach explicitly based on the growth mindset framework for intellectual performance. In one class, students receive feedback emphasizing strategies, effort, and learning from mistakes; in another, feedback emphasizes being "smart" or "not smart." Both classes cover identical material and take the same cumulative exam. Based on the scenario, which outcome would be most expected according to growth mindset research as commonly applied in education?
4. A sociologist uses functionalism to study how education and family jointly contribute to socialization in adolescence. In a national sample (n = 3,000), adolescents who report consistent household routines (regular dinner times, set bedtimes) also report higher school attendance. Schools in the sample that provide structured morning check-ins show a smaller attendance gap between students with and without consistent household routines. Based on functionalism, which conclusion is most consistent with these findings?
5. In a workplace setting, a team has a strong norm of consensus: members avoid voting and prefer unanimous agreement. When a deadline approaches, discussions become longer and members hesitate to express dissenting views, fearing they will slow progress. The team ultimately chooses a familiar option without fully evaluating alternatives. Which group dynamic is most directly illustrated?
6. In a study of startle modulation, participants hear a brief burst of noise every 30 seconds and their whole-body startle is measured. Startle magnitude declines over the first 15 bursts. The researcher then presents a single burst that is slightly louder than the others, followed by the original standard burst. Startle to the standard burst increases compared to the immediately preceding standard burst. Which statement is most consistent with dishabituation?
7. A team investigates levels of processing. Participants see 80 words and answer one question per word: either "Is the word printed in uppercase?" (shallow) or "Is the word pleasant?" (deep). After a 20-minute filler task, participants complete surprise free recall. The words are balanced for frequency and length. Which statement best reflects the memory process described?
8. A hospital system introduced an optional "cultural background" field in patient records to improve communication. Over time, staff began using that field to make assumptions about patients' pain tolerance and medication adherence, especially when patients were recorded as "Hispanic/Latino," despite wide variation in national origin and language among those patients. The system observed unequal pain management across groups. Which conclusion is most consistent with racialization in this context?
9. A job applicant, worried about their performance in an upcoming interview, tells the interviewer that they were up all night with a sick family member. Even if this is an exaggeration, it could be an impression management strategy known as:
10. Researchers conducted a social experiment to examine implicit bias in hiring. Adult participants (N=120) reviewed one résumé for an entry-level analyst position; résumés were identical except for the applicant name, which was randomly assigned to signal either Group X or Group Y membership. Participants then rated "overall competence" (1–7) and recommended either an interview or no interview. Participants also completed an Implicit Association Test (IAT) contrasting Group X vs Group Y with "competent" vs "incompetent." Mean competence ratings were similar across conditions, but interview recommendations differed: 62% recommended interviews for the Group Y name versus 44% for the Group X name. IAT scores were positively correlated with the likelihood of recommending an interview for the Group Y name (r = 0.32). Which statement best reflects the findings of the study?
11. A researcher examines how attention shapes somatosensory perception. Participants place their left hand on a table while a mild vibration is delivered to either the index finger or the ring finger. In one condition, participants perform a demanding mental math task during stimulation; in another, they focus solely on the sensation. Detection thresholds (lower = more sensitive) are measured. Finding: detection thresholds are higher during mental math than during focused attention. Which interpretation is most consistent with the results?
12. A clinician interviews a 17-year-old who says, "I've decided I'm going to be a lawyer because that's what my family has always done. I haven't really looked into other paths." The clinician discusses this using Erikson's identity vs role confusion framework. Which statement best reflects the theory illustrated by this scenario?
13. Researchers assessed absolute threshold for detecting a faint tactile pulse delivered to the ankle, relevant to fall-prevention devices. The stimulus intensity was adjusted until participants detected it on 50% of trials. One participant's threshold increased after applying a topical anesthetic. Which conclusion is most consistent with the concept tested?
14. A comparative case study examined discrimination in a restaurant chain. At Location 1, a manager occasionally seated customers from Group F farther from windows despite available tables. At Location 2, corporate policy required servers to obtain manager approval before seating parties larger than four, and the manager was often unavailable during peak hours. Employees reported that large parties from Group F were more frequently asked to wait, even when similar-sized parties from other groups were seated after brief negotiation. The authors distinguished individual discrimination (manager's seating choices) from institutional discrimination (corporate procedures that systematically delay service for some groups). They referenced symbolic interactionism, emphasizing how repeated interactions can signal social value. Which interpretation is most consistent with the study's framing?
15. In a campus lab, participants play a simple computer game where pressing the spacebar can earn points exchangeable for a small gift card. The program delivers 10 points after every 20th spacebar press (responses between reinforced presses earn nothing). After 5 minutes, the researchers switch the program so that 10 points are delivered after an unpredictable number of presses averaging 20. Based on this change from a fixed ratio to a variable ratio schedule, which change in behavior is most likely to occur during the next 5 minutes?
16. A case study described Jordan, a graduate student from a group stereotyped as having poor public-speaking ability. During a departmental talk, Jordan noticed that the audience included several senior faculty who had previously discussed "communication weaknesses" among students from Jordan's background. Jordan reported focusing on not "sounding like the stereotype," rehearsing sentences internally while speaking, and interpreting minor stumbles as evidence of confirming others' expectations. In a later lab meeting with only close peers present, Jordan spoke fluidly and volunteered more frequently. Based on the vignette, what conclusion is most consistent with stereotype threat?
17. In a study of spacing effects on long-term storage, participants learned 60 foreign-language word pairs. Group M studied all pairs in one 30-minute session. Group S studied the same total time split across three 10-minute sessions on three consecutive days. Both groups completed an immediate test after their final study period and a delayed test two weeks later. Immediate scores were similar across groups. Based on the scenario, which conclusion is most consistent with the spacing effect?
18. The term 'comorbidity' refers to:
19. In a rural county, two towns rely on different water systems. Pine Hollow (lower median income) uses shallow private wells, while Lakeview (higher median income) uses a municipally treated system. After heavy rains, Pine Hollow residents report stomach illness and avoid drinking tap water. Testing finds nitrate levels above the local safety threshold in 22% of Pine Hollow wells vs 2% of Lakeview household samples. Over the past year, the rate of emergency department visits for acute gastrointestinal illness was 34 per 1,000 residents in Pine Hollow vs 15 per 1,000 in Lakeview. Pine Hollow also has fewer primary care clinics and longer travel times to the nearest hospital. Which intervention would most likely reduce the health disparities described?
20. A bank assessed loan approvals after implementing a standardized credit-scoring cutoff. Loan officers also had discretion to request "additional documentation" when they felt an application was "unclear." The bank's report discussed institutional discrimination (organizational practices yielding unequal outcomes) and individual discrimination (differential treatment by a specific officer). The authors referenced Weber's bureaucracy, noting that formal rationality can obscure inequities when rules are treated as inherently fair. Which scenario best illustrates institutional discrimination as described?
