1. A study tested endogenous (goal-directed) attention, the voluntary allocation of attention based on expectations. Before each trial, an arrow cue pointed left or right, indicating where a faint visual target was most likely to appear. The cue was valid on 80% of trials. Participants responded when they detected the target. Which result best reflects endogenous attention effects?
2. Researchers design an after-school program guided by Gardner's Multiple Intelligences. Students can demonstrate learning about ecosystems by choosing one of four options: composing a song, building a physical model, writing a persuasive essay, or leading a group discussion. The researchers predict that offering multiple options will change which students appear "high achieving" compared with a single written test. Which outcome would be most expected according to Gardner's Multiple Intelligences?
3. Researchers evaluate a noninvasive stimulation protocol intended to promote neural plasticity in patients with post-stroke memory deficits. Stimulation is paired with a learning task and is delivered only when scalp EEG shows hippocampal-theta–like activity, with the goal of enhancing synaptic strengthening during encoding. Memory is tested with both free recall and recognition 24 hours later. Which outcome would be expected from the neural plasticity approach described if it primarily improves encoding rather than retrieval strategies?
4. A district introduced an "objective" placement test for advanced coursework and stated that it would increase fairness. Students (N = 520) took the same test, but some had prior access to enrichment activities aligned with test content (e.g., debate clubs emphasizing argument structure and vocabulary). These students were more likely to place into advanced tracks. Over the next year, advanced-track students reported better access to school counseling and lower perceived academic stress. Concept tested: cultural capital. Which statement best reflects cultural capital's role in the observed stratification?
5. A person who is typically quiet and reserved attends a large, energetic political rally. Caught up in the excitement of the crowd, they find themselves shouting slogans and chanting along with everyone else, behaviors they would never engage in alone. This change in behavior can be best attributed to:
6. A consulting team examines promotion patterns in a finance company after it introduced structured performance rubrics and anonymized work-sample reviews. Over two review cycles, the gender gap in promotion rates narrowed. The team interprets gender roles as shaping perceptions of competence and leadership, and considers how organizational procedures can alter gendered expectations in evaluation contexts. Which statement best reflects the impact of changing gender-role dynamics on promotion-related social processes?
7. In a study of perspective-taking, children watched a short story in which one character hid a toy in a blue box and left the room. A second character then moved the toy to a red box. Children were asked where the first character would look for the toy upon returning. Most 4-year-olds answered "red box," whereas most 6-year-olds answered "blue box." The researcher argues that the change reflects a key advance in cognitive development rather than simple memory for the story. Which explanation best describes the observed change?
8. To test Drive Reduction Theory, researchers induced mild hypoglycemia in a controlled setting (within safe limits). Participants then completed a computer task where they could press a key repeatedly to earn small food rewards. Blood glucose was lower in the hypoglycemia condition, and participants reported stronger hunger. Which result is most consistent with Drive Reduction Theory and the biological drive? Assume pressing the key requires effort but is feasible.
9. The discrepancy between the rapid technological advancement and the slower development of corresponding social norms described in the passage is best explained by the concept of:
10. After a difficult chemistry exam, Priya receives an A. She tells her classmates that she did well because she is "naturally good at science" and "always thinks clearly under pressure." Two weeks later, she receives a C on the next exam and says the test was unfairly written and that the room was distracting. She does not mention changes in study time between the two exams. How does the vignette illustrate a self-serving bias?
11. A school district enrolls a growing number of students whose families recently immigrated from several different regions. The district introduces an approach in which students can complete some projects using examples from their home cultures, a heritage-language club is funded, and teachers are trained to include multiple historical perspectives in lesson plans. At the same time, all students share the same core academic standards and participate in joint extracurricular activities. This scenario focuses on multiculturalism. Based on the scenario, which outcome would be most consistent with multiculturalism?
12. In the canonical biological stress response pathway implicated in several psychological disorders, the hypothalamus releases corticotropin-releasing hormone (CRH), which stimulates the anterior pituitary gland to release which hormone?
13. A researcher observes two siblings during a conservation task. The younger child (age 5) sees water poured from a short, wide glass into a tall, narrow glass and says the tall glass has "more water." The older child (age 9) says the amount is the same and explains that "it just changed shape." The researcher interprets this as age-related change in logical operations applied to concrete objects. Which statement best explains the older child's response?
14. In a dichotic listening paradigm, participants heard different syllables presented simultaneously to each ear. When asked to report what they heard, right-handed participants more often reported the syllable presented to the right ear. The effect was strongest for speech-like stimuli and diminished for nonlinguistic tones. Based on the vignette, which conclusion about auditory processing is most consistent?
15. A 30-month-old produces "Me want cookie" and "Doggie run," and caregivers report a recent increase in vocabulary size over a few weeks. The pediatrician references typical language acquisition milestones without invoking any additional theory. Which finding would be most consistent with the child's current stage of language development?
16. Sasha is a clinic receptionist recently assigned as "front-desk trainer," meaning she must correct other receptionists' errors. She still reports to the office manager, who tells her to avoid confrontation and "keep the atmosphere friendly." When a new receptionist repeatedly misfiles patient forms, the nurse supervisor asks Sasha to document the errors for compliance purposes. Sasha says, "I'm supposed to correct and document, but I'm also supposed to avoid confrontation." What role-related tension is most evident?
17. Researchers studied hiring discrimination in a retail chain using a comparative design. In phase 1, matched resumes differed only by the presence of a disability-related student organization leadership role; recruiters decided whether to invite applicants to interview. In phase 2, the chain's scheduling policy was reviewed: new hires were required to have "open availability" (any shift, any day) for the first six months. The authors referenced social model of disability (barriers are socially produced) and rational choice theory to discuss employer incentives. Result: resumes signaling disability leadership received fewer interview invitations. The open-availability rule disproportionately excluded applicants who required predictable schedules for medical appointments. What conclusion is most consistent with distinguishing individual from institutional discrimination here?
18. A school counselor interviews two students. Student A (age 13) reports frequent arguments with parents about curfews and clothing, but also describes relying heavily on peers for feedback about "who I am." Student B (age 18) reports fewer conflicts at home and describes making plans based on personal values, even when friends disagree. Which interpretation best fits typical developmental trends in adolescence?
19. A hospital studied readmission rates after discharge for heart failure. All patients received the same printed instructions. Lower readmissions were observed among patients who reported having someone to help interpret instructions, coordinate medications, and arrange follow-up visits. Patients living alone or with limited community ties more often missed follow-up appointments. Readmissions were higher in this group. Concept tested: social capital. Based on the vignette, which conclusion is most consistent with the concept of social capital?
20. A study compares memory strategies in children (age 7) and adolescents (age 15). During a word-list recall task, adolescents spontaneously group words by category (e.g., animals, foods), whereas younger children more often rehearse words in the presented order. Adolescents show higher recall. Which explanation best accounts for the observed age-related difference?
