Document Summary
Psychology 1b lecture"s 1 & 2 & week 1 tutorial. Learning is any enduring change in the way an organism responds, based on its experiences. It is inferred from behaviour that is observed. Habituation is the reduction in response strength to learnt behaviours. Classical conditioning: this is also known as pavlovian or respondent conditioning. It is the learning of a new association between corresponding stimuli. An unconditioned stimulus naturally elicits a response to the stimuli, it doesn"t need to be learnt. Generalisation: if a response is conditioned to one stimulus, the organism may also respond to a similar stimulus. Discrimination: means no response to a dissimilar stimulus. Extinction: weakening of the conditioned response when the conditioned stimulus is presented without the unconditioned stimulus. Perception: selection, organisation and interpretation of received information. Psychophysics: refers to the process where physical stimuli are translated in to psychological experiences. Gustav fechner: formulated the theories of detectable stimulus and absolute thresholds.
