  1. Conditional relation
    A relation in which the significance of one stimulus or event depends on the status of another stimulus
  2. Configural-cue Approach
    An apporach to the analysis of stimulus conrtol which assumes that organisms respond to a compound stimulus as an integreal whole rather than a collection of separate and independent stimulus elements
  3. Discriminintive Stimulus
    A stimulus that controls the performance of instrumental behavior because it singals the availability (or non availability) of reinforcement.
  4. Excitatory generalization gradient
    A gradient of responding that is observed when organisms are tested with the S+ from a discrimiation procedure and with stimuli that increasingly differ from S+. The highest level of responding occurs to stimuli similar to the S+, progressively less responding occurs to stimuli that increaseinlg differn from the S+ this the gradient has an inverted U shape
  5. Inhibitory Generalizaiton gradieint
    A gradient of responding that is observed when organisms are tested with the S- from a discrimiation procedure and with stimuli that increasingly differ from S-. The lowest level of responding occurs to stimuli similar to the S-, progressively less responding occurs to stimuli that increaseinlg differ from the S- this the gradient has an U shape
  6. Faciliation
    a procedure in which one cue designates when another cue will be reinforced. (occasion setting)
  7. intradimensional discrimiation
    a dsicrimination between stimuli that differ only in terms of the value of one stimulus feature, such as color, brightness or pitch
  8. modulator
    a stimulus that signals the relation between two other events. The nature of a binary may be determeined by a third event, call a modulator
  9. overshadowing
    interference with conditioning of a stiumuls becasue of the simultatneous prescene of another stimulus that is easier to conditon
  10. peak-shift effect
    a displacement of the highest rate of responding in a stimulus gerneralization gradient away from the S+ in a direction opposite the S-
  11. stimulus discrimination
    differential responding in the presence of two or more stimuli
  12. stimulus discrimiation procedure (classical)
    a classical coniditoing procedure in which one stimulus (the CS+) is paired with the unconiditoned stimulus on some trials and another stimulus (the CS-) is presented without the unconiditoned stimulus on other trials. As a result of this procedure the CS+ comes to elict a conditioned repsonse and the CS- comes to inhibit this response.
  13. Stimulus discrimination proceudre (instrumental)
    a proceudre in which reinforcement for responding is available whenever one stimulus (S+) is present and not available whenver another stimulus (S-) is present
  14. Stimulus element apporach
    An approach to the analysis of control by compound stimuli which assumes that partipants respond to a compound stimulus in terms of the stimulus elelemnts that make up the compound.
  15. Stimulus equivalaence
    responding to physically distinct stimuli as if they were the same becasue of common prior expereinces with the stimuli
  16. Stimulus generalization
    responding to test stimuli that are differnt form the cues that were present during training
  17. stimulus generalization gradient
    a gradient of responding that is observed if participants are tested with stimuli that increasingly differ from the stimulus that was present during training.
