Document Summary
Psyc 203 chapter 4- measurement and data analysis. What to measure- varieties of behaviour: the variety of behaviours measured by experimental psychologists is virtually unlimited, ranges from overt behaviour to self-report to recordings of physiological activity. Research example- habituation: this habituation procedure involves showing an infant the same stimulus repeatedly and then changing to a new stimulus. It is known that infants prefer to look at events that are new to them, so if the same stimulus is presented repeatedly, they lose interest (they stop looking) If looking time in response to stimuli decreases and then suddenly increases, you can infer that the infant has noticed something new: kim and spelke (1992) showed that infants around 7 months have a concept of gravity. Evaluating measures: how can you tell if a procedure for measuring behaviour is any good, reliability, validity.
