Conditioned response (C* - response associated with 8CS elicited by CS 7abituation- responding less strongly o$er time to repeated stimulus. 5$ersi$e conditioning- classical conditioning to an unpleasant 8CS. -ypes of reinforcement! o /ositi$e reinforcement- positi$e outcome or conse9uence of a beha$ior that strengthens the probability of the beha$ior. o ?egati$e reinforcement- remo$al to negati$e outcome of a beha$ior that strengthens probability of the beha$ior. /unishment- outcome or conse9uence of a beha$ior that wea&ens probability of the beha$ior. 5c9uisition- leaning phase where a conditioned response is established% e'tinctionreduction)elimination of conditioned response% and spontaneous reco$ery- reemergence of e'tinct C* after a delay in CS. Stimulus generali.ation- similar CS elicits the C* $s. stimulus discrimination- less pronounced C* to a CS different from original CS. 7igher order conditioning- de$eloping a C* to a CS by associating it to another CS. -he law of effect- if a stimulus followed by a beha$ior results in a reward% the stimulus is more li&ely to cause the beha$ior in the future. Schedules of reinforcement o 4i'ed ratio (4* schedule- reinforcement after a number of responses. o 4i'ed inter$al (40 schedule- reinforcement after a specific time inter$al. o @ariable ratio (@* schedule- reinforcement after a random number of responses. o @ariable inter$al (@0 schedule- reinforcement after a random time inter$al. Shaping- conditioning beha$ior by reinforcing beha$iors that comes closer and closer to target. Chaining- lin&ing a number of unrelated beha$iors that form a longer series. /remac& principle- less fre9uently performed beha$ior can be increased in fre9uency by reinforcing it with a more fre9uent beha$ior. -o&en economies (secondary and primary reinforcers - patients who beha$e in a desired fashion recei$e secondary reinforcers% which can be trade for primary reinforcers. 7igher-order conditioning and addictions- conditioning a response to a conditioned stimulus by $irtue of its association with another conditioned stimulus. 5ssociation to things that cause a dri$e for those things causes addictions. 5c9uisition of phobias- through classical conditioning.
