A friend walking away from you does not seem to shrink, even though their image on your retina gets smaller. This is called:
In Treisman's feature integration theory, why is finding a red X among red Os and blue Xs slow?
Older adults often prefer spending time with a few close friends rather than meeting new people. Carstensen's socioemotional selectivity theory explains this as:
Cross-sectional studies suggested large declines in intelligence after middle age, but Schaie's longitudinal data showed smaller declines. A main reason for the difference is:
Which concept describes believing that others share our opinions more than they actually do?
After choosing between two similarly rated household appliances, participants rated the chosen one higher and the rejected one lower than before. This is called:
Patients taking monoamine oxidase inhibitors (MAOIs) must avoid foods rich in tyramine because:
A therapist helps a client with panic disorder deliberately bring on dizziness by spinning in a chair, without using safety behaviours. What is this technique called and why is it used?
Answer: B · Size constancy
Size constancy keeps the perceived size of an object stable despite changes in retinal image size, by combining image size with perceived distance.
Answer: B · Combining features (a conjunction) requires focused attention to each item
Single features are detected in parallel, but conjunctions of features must be bound with serial, focused attention, so search time increases with the number of items.
Answer: D · Focusing on emotionally meaningful goals as time feels shorter
When time horizons shrink, people focus on emotionally satisfying relationships rather than gathering new information or contacts.
Answer: C · Cohort effects, such as differences in education between generations
Older cohorts often had less schooling, so cross-sectional comparisons overstate age decline. Longitudinal data separate ageing from generation, though they suffer from attrition.
Answer: A · False consensus effect
The false consensus effect is the tendency to overestimate how common our own attitudes and behaviours are.
Answer: B · Spreading of alternatives after a decision
Post-decision dissonance is reduced by increasing the attractiveness of the chosen option and lowering that of the rejected one.
Answer: D · The combination can cause a dangerous rise in blood pressure
MAO normally breaks down dietary tyramine. When it is inhibited, tyramine can trigger a hypertensive crisis, which is why MAOIs require dietary restrictions.
Answer: A · Interoceptive exposure, so the client learns bodily sensations are not dangerous
Interoceptive exposure provokes feared bodily sensations so the client can test catastrophic predictions and habituate. It is a core part of CBT for panic disorder.
