explain behaviourist approach
-Only interested in studying behaviour that can be observed and measured.
-behaviourists rejected introspection as it involved too many concepts that were vague and difficult to measure
-tried to maintain control and objectivity within research so relied on lab studies to achieve this
-Believe behaviour is learned, describe a baby's mind as a 'blank slate' that is written on by experience
-believe basic processes that govern learning are same in all species so replace humans with animals in research -two forms of learning: classical and operant conditioning
