The cognitive theories and treatments in use today have generally followed on from Beck’s original theories. Broadly speaking, cognitive approaches to emotional disorders focus on two main areas of a person’s experience; the appraisals a person makes while in a situation, and the information processing biases that occur. In anxiety, appraisals that are made generally […]

As the two-factor model implies, once maladaptive behaviour has been learnt it will be maintained only if the right conditions exist. Therefore treatment must be preceded by functional analysis to establish which conditions are responsible for maintaining the behaviour in question— including stimuli, prompts and reinforcers. To assist with this, the STAR system can be […]

Formation of behaviour disorders

Behavioural therapies are based on the assumption that mental disorders are maladaptive behaviours which have resulted from faulty learning. The case of Little Albert, given in Chapter 1, provides an example of the way that phobias may be learnt. The solution is therefore to unlearn the behaviours. Learning occurs through either association (classical conditioning) or […]

Criteria for defining abnormal behaviour

Abnormal behaviour has been defined using five different sets of criteria: •statistical criteria define it as deviation from the average •deviation-from-the-norm criteria define it as deviation from expected ways of behaving •mental health criteria define it as the absence of socially desirable characteristics and behaviours (Jahoda 1958) •social/psychological criteria define it by the presence of […]
