This includes discoveries relating to the role of the prefrontal cortex in behaviour, understanding learning and memory, modelling Parkinson's disease, and the role of the amygdala in conditioned reinforcement.

"' Information hypothesis of conditioned reinforcement "'( Berlyne, 1960; Bloomfield, 1972, Rachlin, 1976 ) states that the conditioned reinforcing strength of a stimulus is a function of its informativeness about the availability of primary reinforcement.

For example, a child may see their pet dog and say " dog "; the nonverbal stimulus ( dog ) evoked the response " dog " which is maintained by praise ( or generalized conditioned reinforcement ) " you're right, that is a dog !"

Also, it is unclear what factors affect relative resistance to change of responding maintained by conditioned reinforcement ( Shahan & Podlesnik, 2005 ) or two concurrently available responses when different rates of reinforcement are arranged within the same context for those responses ( e . g ., Bell & Williams, 2002 ).
5.
When all the extant resistance to change and preference data were summarized by Grace, Bedell, and Nevin ( 2002 ), they found that those measures were related by a structural relation slope of 0.29 . Therefore, relative resistance to change and preference both have been conceptualized as expressions of an underlying construct termed response strength, conditioned reinforcement value, or more generally, behavioral mass of discriminated operant behavior ( see Nevin & Grace, 2000 ).
