1. In a historical labor campaign, textile workers in two towns face similar wage cuts. Town X has multiple unions, a local strike fund, and sympathetic clergy; Town Y has fragmented workplaces and no strike fund. Using resource mobilization theory, analysts predict that collective action is more likely when movements can marshal material and organizational resources. Which outcome is most consistent with resource mobilization theory?
2. In a longitudinal review of a hospital system, administrators compared patient access to specialty referrals before and after implementing a standardized "utilization management" rule: referrals required prior authorization plus documentation of two failed lower-cost treatments. Clinicians also completed an implicit-bias training module during the same year. The researchers distinguished individual discrimination (clinician-level differential treatment) from institutional discrimination (rules that systematically disadvantage a group). They referenced fundamental cause theory (flexible resources shape health outcomes) and the concept of cumulative disadvantage. Referral completion rates (within 60 days): - Year 1 (pre-rule): Group X 55%, Group Y 54% - Year 3 (post-rule): Group X 52%, Group Y 41% Which example best illustrates institutional discrimination in this scenario?
3. A clinical trial assessed patients taking an antihistamine that commonly causes drowsiness. Participants showed slower reaction times to sudden visual flashes but unchanged ability to detect the flashes when asked without time pressure. The investigators suggested slowed central processing rather than impaired retinal transduction. Based on the scenario, which outcome is most consistent with the neural mechanism discussed?
4. Researchers investigate how divided attention affects encoding. Participants view 60 images (half emotionally neutral, half mildly negative) while either (Condition 1) focusing only on the images or (Condition 2) simultaneously performing a demanding auditory 2-back task. After a 30-minute delay, participants complete a recognition test for the images. The researchers predict an encoding-based effect rather than a change in retrieval strategy. Which outcome would be expected given the described memory context?
5. A perception experiment investigates how attention affects early sensory processing. Participants fixate on a central cross while two faint light flashes occur simultaneously: one on the left and one on the right. A cue arrow appears briefly before the flashes, pointing left or right. A valid cue correctly indicates the side where the participant should report whether a flash occurred; an invalid cue points to the opposite side. Detection accuracy is measured. Which result most likely best reflects the role of attention in information processing?
6. During a community demonstration, organizers note that participants in the center of the crowd—where individuals are tightly packed and many wear similar hats—are more likely to shout profanity and ignore requests to stay on sidewalks. The organizers suspect deindividuation. Which behavior would be expected under deindividuation conditions?
7. A study tested whether attentional resources are modality-specific (separate pools for vision vs. audition) or shared. Participants performed either (1) a visual tracking task alone, (2) an auditory tone discrimination task alone, or (3) both tasks simultaneously. Dual-task interference refers to performance declines when tasks compete for shared resources. Which result most supports shared attentional resources across modalities?
8. A regional bloc introduced a common external tariff and streamlined customs procedures among member states. Small firms reported easier access to intermediate goods from neighboring countries, and cross-border commuting increased in border towns. However, some domestic producers complained about stronger competition from firms within the bloc. Central concept: regional economic integration and market expansion. Based on the scenario, which conclusion is most consistent with the effects of transnational processes?
9. A country transitioning from Stage 2 to Stage 3 reports that family size norms are changing and contraception is more widely available. A simplified pyramid comparison is provided: Earlier 0-19 |||||||||||| 20-39 |||||| 40-59 ||| Later 0-19 |||||||| 20-39 ||||||| 40-59 ||||Which trend is most likely to occur as this transition continues?
10. A nonprofit tests two donation appeals under the elaboration likelihood model. One email contains a detailed breakdown of how each dollar is spent and links to audited reports. The other email uses a short message with a striking photo and the line "Join thousands who already gave." For recipients who are distracted and reading quickly on their phones, which outcome is most consistent with the model?
11. A researcher evaluates Gardner's Multiple Intelligences in an after-school program. Students choose one of four project tracks for 8 weeks: composing music, designing a community garden, writing short stories, or leading peer-mediation sessions. At the end, each student completes (i) a traditional timed verbal-quant test and (ii) a performance assessment aligned to their chosen track (e.g., a judged composition for the music track). Based on the scenario, which conclusion is most consistent with Gardner's theory?
12. Researchers test Drive Reduction Theory using a within-subject design. Participants complete two sessions: in one, they drink a high-salt broth; in the other, they drink a low-salt broth matched for volume and temperature. Immediately afterward, they can choose to work on a tedious button-press task that earns either water or a savory snack. The investigators highlight that increased plasma osmolality activates osmoreceptors and hypothalamic circuits that generate thirst. Based on Drive Reduction Theory, which pattern of reward selection is most consistent with the theory?
13. In a study of taste preference, participants sampled two soups that were identical except for sodium level (low vs moderate). Before tasting, half were told they had just completed a "salt depletion" exercise (false feedback), while the other half were told their salt levels were normal. Those given depletion feedback rated the moderate-sodium soup as more pleasant and chose it more often for a take-home option, even though both groups could detect the salt difference. Which explanation best aligns with the observed preferences?
14. Researchers studied two districts within the same country that has large income inequality. District A has high average income but also high housing costs; District B has lower average income and more crowded housing. Both districts have the same publicly funded childhood vaccination policy. However, District B has lower vaccination uptake and higher rates of vaccine-preventable illness. Interviews suggest many caregivers in District B lack paid leave, rely on hourly wages, and face unstable childcare; some report distrust due to prior negative experiences with institutions. The researchers framed this as a socioeconomic gradient in health that mirrors global inequality, in which structural barriers limit the ability of disadvantaged groups to convert formal entitlements into actual health protection. Which statement best explains the health disparities observed in the data?
15. A cognitive neuroscience group studied sound localization using tones presented from directly in front of participants, but with subtle filtering that mimicked the spectral changes normally produced by the outer ear. When the filtering corresponded to a "sound from above," participants often reported the tone as elevated even though the speaker was at ear level. Which statement best explains the auditory phenomenon described?
16. A city introduces a policy that requires proof of a long-term local address to qualify for a rental assistance program. Shortly afterward, social workers report that recently arrived migrants—who often live temporarily with friends—are less able to access the program despite similar income levels to long-term residents. Which conclusion is most consistent with the social dynamics described, focusing on how policy can shape inequality?
17. A clinic evaluates a patient who reports "blanking" during exams despite doing well on practice questions at home. The clinician notes that the patient studies in a quiet bedroom using typed notes but takes exams in a crowded lecture hall with a strict time limit. When the patient completes a practice test in the lecture hall under timed conditions, performance improves markedly without additional studying. Which outcome would be expected given a context- and state-dependent retrieval account of the patient's difficulty?
18. Participants listened to a sequence of evenly spaced tones (metronome-like), but every fourth tone was physically identical to the others while being preceded by a brief burst of noise. Many participants reported that the fourth tone sounded louder or more "accented" than the rest, despite identical intensity. The effect decreased when attention was diverted to a visual tracking task. Which statement best explains the auditory phenomenon described?
19. A public health department reviews neighborhood-level birth records and finds that infants born to mothers who identify as "Black" have higher rates of low birth weight than those born to mothers who identify as "White," even after adjusting for income and education. In interviews, several mothers report frequent experiences of being treated as "less responsible" by clinic staff based on appearance and name, regardless of their stated ethnicity or country of origin. The department proposes training focused on reducing biased assumptions in clinical encounters. Which conclusion about race and ethnicity is most consistent with the scenario?
20. Which of the following experiences is most characteristic of urban life, according to Louis Wirth's theory of urbanism?
