  1. acquired-drive
    a source of motivation for instrumental behavior caused by the presentation of a stimulus that was previously condtioned with aprumary or uncondtioned reinfrocer
  2. avoidance
    an instrumental conditioning procedure in which the participant's behavior prevents the delviery of an aversive stimulus
  3. avoidacne trial
    a trial in a discriminated avoidance proceudre in which avoidance respsonse is made and prevents the delivery of the aversive stimulus
  4. discriminative avoidance
    an avoidacne conditoing procedure in which occurecnes of the aversive stimulus are signaled by a conditioing stimulus. Responding during the condtioned stimeuls terminates the CS and prevents the delivery of the aversive uncondtioend stimuls
  5. discrimative punishment
    a proceudre in which responding is punished in the presece of a particlur stimuls and not punished in the absence if that stimulus
  6. escape trial
    a trial during discriminated avoidance training in which the required avoidance respnse is not made and the avserice uncodningred stimulus is presented. Preformance of the instrumental response during the aversice stimulus results in termination of the aversive stimulus. This the organimms is able to escape from the aversive stimulus
  7. escape from fear procedure
    situation in which subjects can learn an instrumental response to escape from or terminate a stimlus that elicits fear. Escape from fear provides a coping mechanism for individuals suffering from excessive fear.
  8. Flooding
    a procedure for extinguishing avoidacnce behaovir in which the conditioned stimulus is presented whihle the participatn is prevent from making the avoidance response
  9. Non discriminated avoidance
    an avoidance conditioning procedure in which occurences of the aversive stimulus are not signaled by an external stimuls. In the absence of avoidance responding, the aversive stimuls is presented periodically as set by the S-S interval. Each occurecnes of the avoidance response creates a preiod of safety determined by the S-R interval dring which the aversive stimulus is not presented.
  10. overcoreection
    a procedure for discourageing behavior in which the partipant is not only required to correct or rectify a mistake but also required ot go beyond that by, for example, extensivly practicing the correct response alternative
  11. predatory immience
    The preceived likelihood of being attacked by a predator. Different species typical defense response occur in the face of differnt degrees of predatory immience
  12. punishment
    an instrumental conditioing proceudre in which there is a positive contingency between the instrumental response and an aversive stimulus. if the participant performs the instrumental response it recieces the aversice stimulus if the participant does not perform the instrumental response it does not receive the aversive stimulus
  13. R-S interval
    the interval between the occurcen of an avoidance response and the next scheduled presentation of the aversive stimulus in a non discrimnative avoidance procedure. thus the R-S interval sets the duration of safety created by reac avoidacne response in a nondiscrimatiee avoidacne proceudre
  14. Response prevention
    blocking the opportunity to make the avoidance resposne that the subject is exposed to a fear stimulus without being able to escape from it
  15. Safety signla
    A stimulus that signlas absence of aversive stimulus
  16. shock frequency reduction
    a hypothesis according to which reduction in the frequency of shock serves to reinfroce avoidance behavior
  17. species specific defense reaction
    species typical resposne animlas perfomr in aversive situatlion, inlcude freezing, flighting or fighting
  18. S-S Interval
    the ineterval between the succesive presenations of the aversive stimulus in a nondiscrimiative avoidance proceure when the avoidance response is not perfomred
  19. time out
    a period during which the opportunity to obtain positive reinforcemnet is removied. This may involve removal of the participant form the situaltion where reinfrocesmay be obtained
  20. two-processes theory of avoidacne
    a theory orgianlly developed to explain discrimatied avoiance learning that presumes the operation of two mechanisms: classical conditioning of fear to the warning signal or CS, and instrumental reinfrocement of the avoidance response through terminatio of the warning signal and consequent fear reduction
