Presentation Transcript
Slide2 l.jpg

What environmental events?

  • Very remote (in time) events {PAST}

    • Natural selection

  • Semi-remote events {PAST}

    • Contingencies (respondent and operant)

  • Current events {PRESENT}

    • Presentation of stimuli (US, CS, SD, SD)

    • Motivational & emotional operations

Behavioral Chains


Slide4 l.jpg

Behavioral Chain

  • A sequence of stimuli and responses.

  • Each response produces a change in the environment that acts as a discriminative stimulus (SD) for the next response.


Slide5 l.jpg

“….behavior does not occur as random strings of unrelated responses but in organized sequences, called chains, in which each successive response produces the stimuli, internal or external, that determine what comes next. And when the time arrives to initiate a new sequence of behavior, that, too, is signaled by a change in stimulus conditions.”

(Dinsmoor, 1995)


Slide6 l.jpg

Task Analysis unrelated responses but in organized sequences, called

  • A task analysis is

    • an analysis of complex behavior and sequences (chains) of behavior into component responses.

TASK ANALYSIS unrelated responses but in organized sequences, called

  • Pick up fork

  • Spear potato

  • Lift fork to mouth

  • Open mouth

  • Place fork in mouth

  • Close mouth

  • Pull fork from mouth


Dual functioning chained stimuli l.jpg
Dual Functioning Chained Stimuli unrelated responses but in organized sequences, called

  • A stimulus in a behavior chain reinforces the response that precedes it.

  • That stimulus also acts as an SD or operandum for the response that follows it.
