psychological problems
Psychology = the science of behaviour and mind
Behaviour refers to observable actions
Mind pertains subjective experiences such as feelings, perceptions, memories, thoughts, motives
and emotions.
~ Behaviourism/science of behaviour
The first attempts to treat psychology as a proper science were made by taking observable
behaviour as the central object of scientific study.
It advocated the use of objective measurements
Central tenet of behaviourism: systematic study of individual or group behaviour is the only way
through which expectations about future behaviour can be made and in turn, formulate
psychological theories.
• Laws of Thorndike are examples of behaviouristic approach (based on studies using
objective measurements)
1. Law of Exercise: relationship between stimulus and response strengthens when the
stimulus is more frequently followed by the same response from and individual (law of
use).
The relationship between a stimulus and a response becomes weaker when a stimulus is
seldomly followed by the same response from an individual (law of disuse).
2. Law of Effect (relatively influential): relationship between stimulus and response
strengthens when the response is rewarded. If punished, the relationship diminishes.
➔ However, once punishment is removed, the undesirable behaviour returns. Studies
conclude that rewarding desirable behaviour is far more powerful.
The cognitive revolution in psychology
Happened after WW2 when psychological researchers considered the behaviourist approach to be
too restricting and focused on gaining insight into underlying mental processes in the mind.
➔ What motives, emotions and thoughts induce an individual to engage in certain
behaviour?
