1Practice problems

1.Cognitive psychologyMedium

Lists of similar-sounding letters (B, G, V, T) are harder to recall immediately than dissimilar letters (F, K, Y, W). This suggests short-term memory:

  1. AMainly codes verbal information acoustically
  2. BStores letters mainly as visual images of their shapes
  3. CMainly codes information by meaning
  4. DHas unlimited capacity for letters
2.Cognitive psychologyHard

Glanzer and Cunitz had participants count for 30 seconds between hearing a list and recalling it. Which result did they find?

  1. ARecall became equal at all positions except the middle
  2. BThe recency effect disappeared, but the primacy effect remained
  3. CBoth effects became larger
  4. DThe primacy effect disappeared, but the recency effect remained
3.Developmental psychologyMedium

Scaffolding refers to:

  1. ASupport given to a learner that is reduced as competence grows
  2. BLetting children discover everything alone
  3. CPunishing errors so they are not repeated
  4. DBuilding one fixed curriculum that every child must follow in order
4.Developmental psychologyHard

Ainsworth's sensitivity hypothesis proposes that secure attachment results mainly from:

  1. AThe amount of time the infant spends with any adult
  2. BThe infant's genetic temperament only
  3. CThe caregiver responding promptly and appropriately to the infant's signals
  4. DStrict feeding schedules
5.Social psychologyMedium

Deindividuation refers to:

  1. AThe process of forming a stable, separate personal identity during adolescence
  2. BBecoming more individual when alone
  3. CChoosing not to join any group
  4. DLoss of self-awareness and personal responsibility in groups or anonymity
6.Social psychologyHard

Zanna and Cooper gave participants a placebo pill, telling some it would make them tense. After writing a counter-attitudinal essay, those told the pill causes tension showed little attitude change. This supports the idea that:

  1. APlacebo pills themselves cause attitude change
  2. BWriting essays never changes people's attitudes
  3. CDissonance involves arousal that people try to explain
  4. DSelf-perception theory explains all attitude change
7.Clinical psychologyMedium

Which statement about the monoamine hypothesis of depression is most accurate?

  1. AIt predicts that antidepressants improve mood within a few hours of a dose
  2. BIt links depression to low monoamine activity but struggles to explain the delayed drug response
  3. CIt has been fully confirmed by direct measurements of serotonin levels in the brains of living patients
  4. DIt proves that depression is caused only by low dopamine in the frontal lobe
8.Clinical psychologyHard

A man says that a famous singer is secretly in love with him and sends him coded messages through her songs. Apart from this, his thinking and behaviour are normal, with no hallucinations. Which diagnosis fits best?

  1. ASchizophrenia, paranoid type
  2. BBipolar disorder with mania
  3. CDelusional disorder, erotomanic type
  4. DNarcissistic personality disorder

2Solutions

1.Cognitive psychology

Answer: A · Mainly codes verbal information acoustically

Why this is the answer

The phonological similarity effect shows that verbal short-term memory relies on sound-based codes. Long-term memory relies more on meaning.

Answer

A · Mainly codes verbal information acoustically
2.Cognitive psychology

Answer: B · The recency effect disappeared, but the primacy effect remained

Why this is the answer

The delay displaced the last items from short-term memory, removing recency. Early items had already been rehearsed into long-term memory, so primacy was unaffected.

Answer

B · The recency effect disappeared, but the primacy effect remained
3.Developmental psychology

Answer: A · Support given to a learner that is reduced as competence grows

Why this is the answer

Wood, Bruner and Ross described scaffolding as adjustable support that helps a learner work within the zone of proximal development.

Answer

A · Support given to a learner that is reduced as competence grows
4.Developmental psychology

Answer: C · The caregiver responding promptly and appropriately to the infant's signals

Why this is the answer

Ainsworth argued that caregiver sensitivity and responsiveness predict secure attachment. Critics such as Kagan emphasised infant temperament.

Answer

C · The caregiver responding promptly and appropriately to the infant's signals
5.Social psychology

Answer: D · Loss of self-awareness and personal responsibility in groups or anonymity

Why this is the answer

Anonymity and group immersion can reduce self-awareness, making behaviour that violates norms more likely.

Answer

D · Loss of self-awareness and personal responsibility in groups or anonymity
6.Social psychology

Answer: C · Dissonance involves arousal that people try to explain

Why this is the answer

When participants could misattribute their discomfort to the pill, they had no need to change attitudes. This suggests dissonance is an unpleasant arousal state.

Answer

C · Dissonance involves arousal that people try to explain
7.Clinical psychology

Answer: B · It links depression to low monoamine activity but struggles to explain the delayed drug response

Why this is the answer

The hypothesis grew from the effects of drugs on monoamines. The delay of several weeks before benefit suggests that downstream changes, such as receptor adaptation, matter too.

Answer

B · It links depression to low monoamine activity but struggles to explain the delayed drug response
8.Clinical psychology

Answer: C · Delusional disorder, erotomanic type

Why this is the answer

Delusional disorder involves one or more delusions for at least a month without meeting criteria for schizophrenia, and functioning is not markedly impaired apart from the delusion. Erotomanic delusions concern another person being in love with the patient.

Answer

C · Delusional disorder, erotomanic type
