1Practice problems

1.Cognitive psychologyMedium

The cognitive interview is used by police to improve eyewitness recall. Which technique does it include?

  1. AMentally reinstating the context of the event
  2. BAsking leading questions to speed things up
  3. CShowing the witness photos of a single suspect
  4. DAsking only yes-or-no questions
2.Cognitive psychologyHard

In Sperling's experiments, participants saw a 3 × 4 grid of letters briefly. When a tone signalled which row to report immediately afterwards, they could report most letters of that row. What did this show?

  1. AMost of the display is briefly held but fades before it can all be reported
  2. BHearing a warning tone improves visual perception of nearby letters in general
  3. CBriefly seen letters are transferred into long-term memory at once
  4. DIconic memory holds only about four letters, however they are tested
3.Developmental psychologyMedium

Habituation in infant research is used to show that babies:

  1. AAre born with full adult vision
  2. BBecome drowsy and sleep more when the same stimulus is presented over and over again
  3. CPrefer their own reflection
  4. DCan tell two stimuli apart because interest returns when the stimulus changes
4.Developmental psychologyHard

Hazan and Shaver's "love quiz" found that adults' romantic attachment styles:

  1. AMatched infant type proportions and related to recalled childhood care
  2. BWere completely unrelated to how people recalled their childhood
  3. CWere nearly all insecure-avoidant, unlike the proportions of infant types
  4. DChanged completely from one relationship to the next at random
5.Social psychologyMedium

On a New York subway, a man who collapsed while carrying a cane was helped more often than a man who smelt of alcohol. Which model best explains this?

  1. AThe empathy–altruism hypothesis
  2. BThe arousal: cost–reward model
  3. CSocial identity theory
  4. DThe matching hypothesis
6.Social psychologyHard

Pettigrew and Tropp's meta-analysis of over 500 studies on intergroup contact found that:

  1. AContact usually increases prejudice unless groups are kept apart
  2. BContact usually reduces prejudice; Allport's conditions add to it
  3. CContact reduces prejudice only if all of Allport's conditions are met
  4. DContact has no measurable effect once prior attitudes are controlled
7.Clinical psychologyMedium

In the two-factor model of phobias (Mowrer), how is a phobia maintained?

  1. APositive reinforcement of fear by rewards
  2. BPunishment of approach behaviour by others, which strengthens the fear itself
  3. CAvoidance reduces anxiety, which negatively reinforces the avoidance
  4. DThe fear is learned by watching others only
8.Clinical psychologyHard

The "scientist-practitioner" (Boulder) model in clinical psychology means that clinicians should:

  1. AOnly conduct laboratory experiments
  2. BPrescribe medication as their main treatment, following psychiatric guidelines closely
  3. CUse research evidence to guide practice and evaluate their own interventions
  4. DAvoid research completely

2Solutions

1.Cognitive psychology

Answer: A · Mentally reinstating the context of the event

Why this is the answer

The cognitive interview uses context reinstatement, reporting every detail, recalling in different orders and from different perspectives, which increases correct recall.

Answer

A · Mentally reinstating the context of the event
2.Cognitive psychology

Answer: A · Most of the display is briefly held but fades before it can all be reported

Why this is the answer

Whole report gave about four letters, but partial report showed most of any cued row was available, so nearly the whole grid was briefly held. The advantage disappeared when the tone was delayed by about a second.

Answer

A · Most of the display is briefly held but fades before it can all be reported
3.Developmental psychology

Answer: D · Can tell two stimuli apart because interest returns when the stimulus changes

Why this is the answer

When a familiar stimulus is replaced by a new one, a recovery in looking time (dishabituation) shows the infant perceives the difference.

Answer

D · Can tell two stimuli apart because interest returns when the stimulus changes
4.Developmental psychology

Answer: A · Matched infant type proportions and related to recalled childhood care

Why this is the answer

Adults' self-reported styles (secure, avoidant, anxious) appeared in proportions similar to infant studies and related to recalled parental relationships, though data were retrospective self-reports.

Answer

A · Matched infant type proportions and related to recalled childhood care
5.Social psychology

Answer: B · The arousal: cost–reward model

Why this is the answer

Piliavin and colleagues proposed that bystanders weigh the costs of helping and not helping. Higher perceived costs made helping the "drunk" less likely.

Answer

B · The arousal: cost–reward model
6.Social psychology

Answer: B · Contact usually reduces prejudice; Allport's conditions add to it

Why this is the answer

Contact was linked to lower prejudice across many groups and settings. Optimal conditions made the effect larger, but they were not essential for some reduction.

Answer

B · Contact usually reduces prejudice; Allport's conditions add to it
7.Clinical psychology

Answer: C · Avoidance reduces anxiety, which negatively reinforces the avoidance

Why this is the answer

Fear is acquired through classical conditioning and maintained because avoiding the feared object reduces anxiety, negatively reinforcing avoidance.

Answer

C · Avoidance reduces anxiety, which negatively reinforces the avoidance
8.Clinical psychology

Answer: C · Use research evidence to guide practice and evaluate their own interventions

Why this is the answer

The Boulder model trains clinical psychologists to integrate scientific research and clinical practice, the basis of evidence-based practice.

Answer

C · Use research evidence to guide practice and evaluate their own interventions
