Document Summary
End of 19th century functionalism (william james) End of 19th century psychodynamic (sigmund freud) 1920s behaviourism (b. f. skinner, ivan pavlov, john watson) Three levels of analysis for describing various aspects of behaviour and classifying casual factors: biological, psychological, environmental. Biological: everything psychological is biological, can analyze behaviour in terms of brain processes, hormones, and genetics, cannot explain experiences and feelings. Psychological: can analyze role of thought, memory, planning, and problem solving, takes into account motivational, emotional, and personality processes that influence people. Environmental: takes into account the environment, past and present, and personal and cultural that shape and stimulate behaviour. Example: depression: biological genetic factors, disrupted brain rhythms, chemical factors, psychological pessimism, severe losses/rejections from past, environmental non-rewarding environment, loss of social support. Charles darwin: natural selection (survival of the fittest), nothing special about humans, we can be studied scientifically. Ivan sechenov: physiologist, believed all complex behaviour can be explained by reflexes.
