The 20 questions

  1. In Freud's model of personality, which component operates on the reality principle and mediates between the id and the superego?

    • The id, which seeks immediate gratification of instinctive urges and is driven by the pleasure principle alone
    • The superego, which holds internalised moral standards and pressures the individual to act in socially approved ways
    • The unconscious, which stores repressed memories and reflexive motives that cannot be brought into awareness at all
    • The ego, which uses logic and reason to balance the demands of the id against the constraints of the external world

  2. According to Freud, which principle governs the id?

    • The moral principle, which judges actions by conscience and the internalised rules of parents and wider society
    • The pleasure principle, which seeks immediate satisfaction of instinctive urges, including aggressive ones, without moral restraint
    • The reality principle, which delays gratification until a socially acceptable outlet for the impulse can be found
    • The rational principle, which weighs costs and benefits before any action is taken in response to an impulse

  3. In Freud's theory, what is the role of the superego?

    • It seeks immediate pleasure and drives instinctive impulses, including aggressive ones, that are unconscious and unrestrained
    • It stores physical energy for sexual and aggressive drives, which is released through dreams and slips of the tongue
    • It mediates between reality and the instincts, using logic to decide which impulses can be expressed in the external world
    • It holds internalised moral standards and conscience, shaped by parental and social values

  4. In Freud's psychodynamic account, catharsis refers to:

    • the process by which the ego permanently forgets an unacceptable memory so that it no longer affects conscious behaviour
    • the internal conflict between the id and superego that produces anxiety and leads to the development of neurotic symptoms
    • the transfer of instinctive energy from the id into the superego, where it is stored until moral standards can be met
    • the release of built-up aggressive energy through expression or discharge, which Freud argued would reduce the need for aggression

  5. Freud proposed a death instinct, often called Thanatos. How was this linked to aggression?

    • It was a biological hormone that rises at puberty and is produced in the adrenal glands, increasing physical strength
    • It was a conscious plan to protect oneself from threats, which the ego uses to justify the defensive use of force in conflict
    • It was a form of social learning acquired by imitating aggressive adults, which the child copies during early childhood years
    • It was the drive towards self-destruction and, when directed outward onto others, it was seen as a source of aggression

  6. Which of these is an example of a biological explanation of aggression rather than a psychodynamic one?

    • Aggression reflects unresolved conflict between the ego and the id, which builds up anxiety that must be discharged eventually
    • Aggression results from an overly harsh superego that produces guilt and then displaces the feeling onto other people nearby
    • Aggression is linked to hormone levels, such as testosterone, and to activity in brain regions regulating emotion
    • Aggression is driven by an unconscious id that seeks immediate release of pent-up energy through hostile acts or words

  7. Which brain structures are most often linked to the biological explanation of aggression?

    • The hippocampus and the thalamus, which are mainly involved in the storage of new long-term memories and sensory relay
    • The occipital lobe and the temporal lobe, which are mainly involved in processing visual information and sound input
    • The amygdala and the prefrontal cortex, which are involved in emotional responses and in inhibiting impulsive behaviour
    • The cerebellum and the medulla, which control balance, posture and the automatic regulation of heart rate and breathing

  8. A man who is frustrated at work lashes out at his colleague. A Freudian psychodynamic account would most likely explain this by:

    • an id impulse seeking release, with the ego and superego failing to contain the aggressive energy that has built up unconsciously
    • a lowered level of serotonin in the frontal lobes, which reduces the inhibition of impulses and produces sudden violent behaviour
    • a learned response, reinforced by the colleague's reaction in the workplace, which has been strengthened by previous rewards
    • a hormonal surge of testosterone after the frustrating event, which increases aggressive drive in the bloodstream immediately

  9. A patient with damage to the prefrontal cortex begins to show sudden, impulsive aggression that they had previously controlled. Which explanation does this best support?

    • A cognitive explanation, because the patient must have made a conscious decision to become more aggressive after the injury
    • A learning explanation, because the patient must have recently observed aggressive models in their social environment
    • The biological explanation, because the prefrontal cortex helps regulate impulses, and damage can remove that control
    • Freud's superego explanation, because the superego is located in the prefrontal cortex and damage removes all moral guilt

  10. A study finds that a drug that lowers testosterone also reduces aggressive responses in male participants. Which conclusion does this best support?

    • That aggression is unrelated to hormones, since the drug must have had a placebo effect on the participants' expectations
    • That Freud's concept of the id is confirmed, because the drug must have changed the level of unconscious aggressive energy
    • That aggression is entirely caused by testosterone, so any person with low testosterone will never behave aggressively at all
    • That there is some evidence for a biological contribution to aggression, though other factors may also influence its occurrence

  11. Freud's theory is often criticised for being hard to test. Which feature of the theory makes this criticism most likely?

    • It has been tested mainly with animals in the laboratory, so the results cannot be generalised to human behaviour in real life
    • It makes precise, measurable predictions about hormone levels, which can be checked directly with blood samples in laboratories
    • Its concepts such as the id and superego are not directly observable, so they can be used to explain almost any behaviour afterwards
    • It relies on large randomised controlled trials with thousands of participants, which are expensive and difficult to replicate

  12. Which is the strongest argument that the biological explanation of aggression is more scientific than Freud's psychodynamic explanation?

    • It draws on the personal reports of patients about their dreams and childhood memories, which give rich insight into the mind
    • It accepts that aggression has many unconscious causes, which cannot be measured but explain the full range of behaviour seen
    • It relies on case studies of individual patients whose histories were interpreted in depth by a trained clinician during therapy
    • It makes testable predictions and uses objective physiological measures, such as hormone assays and brain scans, that can be replicated

  13. A critic argues that biological explanations of aggression are reductionist. Which point best supports this criticism?

    • They rely on animal studies of hormones, which are always unethical and therefore invalid for any use in psychology at all
    • They treat aggression as entirely learned from parents, which leaves no room for any inherited or physiological causes whatsoever
    • They focus on the unconscious mind in great detail, which makes them too broad to apply to any particular individual in practice
    • They explain aggression mainly through physiology and may underplay social and cultural influences

  14. Research by Bushman and others suggests that venting anger by hitting a punch bag does what to later aggression?

    • It reliably reduces later aggression, supporting Freud's view that aggressive energy is drained by discharge through action
    • It tends to increase later aggression, which contradicts the catharsis idea that releasing anger drains aggressive energy
    • It reduces aggression only in women, since the superego in men prevents any release of aggressive energy outside the body
    • It has no effect on later aggression, showing that the id has no influence on behaviour outside the unconscious mind

  15. A researcher uses Freud's theory to explain why a child who was harshly punished at home feels intense guilt when acting aggressively. Which part of personality is most relevant?

    • The superego, because it internalises parental and social moral standards and produces guilt when they are broken
    • The death instinct, because it directs all aggression back onto the self and causes feelings of guilt as a result
    • The ego, because it uses logic to evaluate each act of aggression and decide whether guilt is a rational response
    • The id, because it seeks immediate gratification and experiences guilt as a physical discomfort in the body

  16. Which is a limitation of the case study method that Freud relied on to develop his psychodynamic theory?

    • Case studies are always fully objective, which means that they cannot be influenced by the personal interpretation of the researcher
    • Case studies involve small, unrepresentative samples and rely on subjective interpretation, so generalisation to others is limited
    • Case studies can only be carried out with animals, so they tell us nothing about the psychological functioning of human beings
    • Case studies produce only numerical data, which makes them too precise to capture the complex meaning of an individual's life

  17. A psychologist compares Freud's explanation of aggression with a biological one. Which difference between the two levels of explanation is most accurate?

    • Both explanations focus on the same level, namely the social environment, and differ only in the terms they use to describe it
    • Both explanations focus on the same level, namely conscious decision making, and differ only in whether they accept free will
    • Freud explains aggression through mental and unconscious processes, while the biological explanation focuses on physiological mechanisms
    • Freud explains aggression at a physiological level, while the biological explanation explains it through unconscious mental forces

  18. A researcher finds that aggressive people in a study have high testosterone and reduced prefrontal activity. Which combined biological interpretation is most justified by these data?

    • Aggression is caused entirely by the prefrontal cortex, because testosterone has no independent effect on the brain at all
    • Aggression is caused by the superego, which is closely linked to testosterone levels and to activity in the prefrontal cortex
    • Hormone and brain measures may relate to aggression, but correlation cannot show the direction of cause
    • Aggression is unrelated to both measures, since two correlated biological variables can never be associated with behaviour

  19. Why might a researcher argue that a biological explanation of aggression offers a more practical application than Freud's theory?

    • Because it can point to targeted treatments, such as drugs that alter hormone or neurotransmitter activity linked to aggression
    • Because it relies only on the personal insight of patients, which makes it easier for clinicians to apply in everyday settings
    • Because it removes the need for any treatment, since aggression is always a conscious decision that individuals can simply stop
    • Because it concludes that aggression is impossible to change, which allows society to plan for it without any intervention

  20. Which best describes an evaluation point about the nature-nurture issue in biological explanations of aggression?

    • They give equal weight to nature and nurture, so they offer a balanced account that avoids any criticism from other theories
    • They emphasise nurture only, so they ignore the influence of genes, hormones and brain structure on behaviour entirely
    • They emphasise nature, so they may underplay how environmental experiences and learning shape the expression of aggression
    • They ignore both nature and nurture, because aggression is treated as a purely random event with no identifiable cause at all
