Distinctions that have been made between behaviour and experience are that behaviour is external or overt and amenable to scientific enquiry whereas, experience is internal, subjective and not open to scientific enquiry.
These distinctions are in fact misleading. Biological psychologists study internal events using ‘scientific’ techniques such as EEG recordings can be classed as behavioural. Cognitive psychologists attempt to investigate thought processes, memory, perception and attention which are all part of internal, private and conscious experience yet, are amenable to scientific enquiry. Insights into these mental processes may be inferred from an individual’ observable response.
Private subjective experience – personal subjective phenomena and unique to the individual. Private subjective experiences are not easily investigated using scientific procedures.
A better distinction is the criterion of accessibility. Behaviour, whether external or not, can be directly observed by a researcher or at least inferred using empirical methods, whereas private subjective experience cannot.
William James, ‘stream of consciousness’ – a internal monologue that is always present, unique, private and accessible only to the individual. People are aware of external events through the combined information from all senses but this cannot be fully verbalised as it is fleeting and therefore, there is too much report. Private subject experience cannot therefore be fully accessed or replicated. People can never perceive the same experience twice because on the second occasion, the event is a different experience.
Introspective reports – report what went through their mind whilst carrying out some action.
Introspective reports couldn’t be verified, were subjective and accessible only to the individual reporting the experience. Only those processes of which the participant was aware could be reported.
Phenomenology – the study of an individual’s subjective and contemporary experience or unique perception of the world. The emphasis is on understanding events from the person’s point of view rather than focusing on behaviour.
