SECTION A
APPROACHES IN PSYCHOLOGY
1.) Describe how Skinner investigated the effect of reinforcement
on behaviour. (4 marks)
Model Answer:
Skinner investigated reinforcement using a device called the Skinner box.
He placed hungry rats or pigeons inside the box and used food pellets as rewards.
When the animal pressed a lever, it was rewarded with food, reinforcing the behaviour.
He found that animals repeated actions that led to positive outcomes, demonstrating
operant conditioning.
, 2.) Outline how evolution might influence behaviour. Give an
example from a topic in psychology. (4 marks)
Model Answer:
Evolution influences behaviour through natural selection, where traits that improve
survival are more likely to be passed on.
One example is infant attachment behaviours, such as crying or clinging, which keep the
caregiver close. Bowlby’s monotropic theory suggests these behaviours evolved to
ensure infants stay near their primary attachment figure.
This increases the chance of protection and survival, meaning such behaviours are
naturally selected over generations.
3.) Describe and evaluate the psychodynamic approach in psychology.
(16 marks)
Model Answer:
The psychodynamic approach, founded by Freud, emphasises the influence of the
unconscious mind on behaviour. It suggests that much of our behaviour is driven by
unconscious conflicts formed in early childhood. The mind is divided into the id, ego,
and superego, which are in constant conflict. Freud proposed that unresolved conflicts
in psychosexual stages can lead to fixation and affect adult personality.
He also introduced defence mechanisms like repression, denial, and displacement to
protect the ego. The approach uses case studies and techniques like dream analysis and
free association to explore unconscious processes.
One strength of the psychodynamic approach is its explanatory power.
This is because it has helped explain a wide range of psychological phenomena, including
personality development and mental disorders. This is useful because it has had lasting
influence on psychology and paved the way for modern therapies such as
psychoanalysis. However, critics argue that many of Freud’s concepts, such as the
unconscious or the Oedipus complex, are not testable or falsifiable.
Another strength is its practical application in therapy.
