1.Cognitive psychologyMedium

Anchoring bias occurs when:

  1. APeople prefer options presented as gains
  2. BAn initial number strongly influences a later estimate
  3. CPeople believe after the event that they knew the outcome all along
  4. DPeople remember only the end of an experience
2.Cognitive psychologyHard

According to Lavie's load theory of attention, an irrelevant distractor is most likely to be processed when:

  1. AThe main task has high perceptual load
  2. BThe main task has low perceptual load
  3. CThe participant is told to ignore it
  4. DThe distractor is presented to the blind spot
3.Developmental psychologyMedium

According to Piaget, assimilation means:

  1. AFitting new information into an existing schema
  2. BChanging an existing schema to fit new information
  3. CForgetting an old schema
  4. DCopying the behaviour of a model
4.Developmental psychologyHard

Which finding is a major criticism of Piaget's formal operational stage?

  1. AAdolescents cannot think abstractly at all, even with specific training
  2. BFormal operations usually appear before concrete operations
  3. CMost children reach formal operations by about age 5
  4. DMany adults do not reason formally, and it depends on schooling
5.Social psychologyMedium

Burger's 2009 partial replication of Milgram stopped at 150 volts for ethical reasons. What did it find?

  1. AObedience was similar to Milgram's at that point
  2. BWomen nearly always refused to continue
  3. CAlmost nobody obeyed in a modern sample
  4. DObedience was far higher than in Milgram's study
6.Social psychologyHard

In Walster's "computer dance" study, students were randomly paired. What best predicted whether they wanted to see their date again?

  1. ASimilarity in intelligence
  2. BSimilarity in personality test scores
  3. CSimilarity in attractiveness, as the matching hypothesis predicts
  4. DThe date's physical attractiveness, regardless of their own
7.Clinical psychologyMedium

Selective serotonin reuptake inhibitors (SSRIs) increase serotonin in the synapse by:

  1. ASpeeding up the breakdown of serotonin by monoamine oxidase enzymes
  2. BDestroying serotonin receptors
  3. CBlocking dopamine release
  4. DBlocking the reuptake of serotonin into the presynaptic neuron
8.Clinical psychologyHard

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?

  1. AFree association, so unconscious fears come to light
  2. BInteroceptive exposure, so the client learns bodily sensations are not dangerous
  3. CAversion therapy, so the client learns to associate panic with physical discomfort
  4. DFlooding, so the client forgets their trauma

2Solutions

1.Cognitive psychology

Answer: B · An initial number strongly influences a later estimate

Why this is the answer

In anchoring, people adjust insufficiently from an initial value, even an arbitrary one, when making numerical judgements.

Answer

B · An initial number strongly influences a later estimate
2.Cognitive psychology

Answer: B · The main task has low perceptual load

Why this is the answer

When the main task uses little perceptual capacity, leftover capacity processes distractors involuntarily. High perceptual load uses up capacity and reduces distractor processing.

Answer

B · The main task has low perceptual load
3.Developmental psychology

Answer: A · Fitting new information into an existing schema

Why this is the answer

In assimilation the child interprets new experiences with existing schemas (calling every animal "dog"); accommodation changes schemas when they do not fit.

Answer

A · Fitting new information into an existing schema
4.Developmental psychology

Answer: D · Many adults do not reason formally, and it depends on schooling

Why this is the answer

Research shows that formal reasoning is far from universal and is strongly linked to schooling and cultural experience, so it is not an automatic stage.

Answer

D · Many adults do not reason formally, and it depends on schooling
5.Social psychology

Answer: A · Obedience was similar to Milgram's at that point

Why this is the answer

Most participants who continue past 150 volts tend to go to the end, so Burger used it as a safe cut-off. Obedience at that point was only slightly lower than Milgram's.

Answer

A · Obedience was similar to Milgram's at that point
6.Social psychology

Answer: D · The date's physical attractiveness, regardless of their own

Why this is the answer

Physical attractiveness of the partner predicted liking for everyone, which did not support the matching hypothesis. Later studies of real couples found more matching.

Answer

D · The date's physical attractiveness, regardless of their own
7.Clinical psychology

Answer: D · Blocking the reuptake of serotonin into the presynaptic neuron

Why this is the answer

SSRIs block the serotonin transporter, so serotonin stays longer in the synaptic cleft. Clinical effects usually take several weeks.

Answer

D · Blocking the reuptake of serotonin into the presynaptic neuron
8.Clinical psychology

Answer: B · Interoceptive exposure, so the client learns bodily sensations are not dangerous

Why this is the answer

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.

Answer

B · Interoceptive exposure, so the client learns bodily sensations are not dangerous
