In 1974 the researchers Baddeley and Hitch argued that the picture of short-term memory (STM) provided by the Multi-Store Model was far too simple. Following the Multi-Store Model‚ it is believed that STM holds limited amounts of information for short periods of time with relatively little processing‚ it is believed to be a unitary store. This means that due to its single store it has no subsystems‚ unlike the Working Memory Model which has many subsystems. This proves that the Working Memory is

Outline and Evaluate the Behavioural Approach to Psychopathology The behavioural model concentrates only on behaviours and the responses a person makes to their environment‚ these can be external or internal. Behaviourists have tended to focus their attention on the role of external events and behaviours as these are more observable and therefore make gaining results easier. This means that not all aspects of abnormality are considered‚ a weakness of the approach as it is selective in its research

Outline and evaluate two models of abnormality (12 marks) The essence of a psychodynamic approach is to explain behaviour in terms of its dynamics – i.e. the forces that drive it. The best known example of this approach is Freud. Freud believed that the origins of mental disorder lie in the unresolved conflicts or childhoods which are unconscious. Medical illnesses are not the outcome of physical disorders but of these psychological conflicts. Conflicts between the id‚ ego‚ and superego create
