Stimulus Control

Stimulus Control

1. Stimulus Control Occurs when the rate, latency, duration, or amplitude of a response is altered in the presence of an antecedent stimulus

   • SD for an Operant Bx is different from
     • Conditioned Stimulus for Respondent Conditioning

2. Sd and Motivational Fxs of Stimuli

   • SD & EO
     • 1) Both events occur before the Bx of interest
     • 2) Both events have evocative Fxs

3. Stimulus Generalization

   • Occurs to the individual when is in presence of another stimuli that shares similar physical properties with the controlling antecedent SD
   • Stimulus Discrimination
     • Stimulus Discrimination occurs when a different stimuli do not evoke the response. 
   • Concept Formation Or Concept acquisition
     • This is a Behavioral outcome of stimulus generalization & stimulus discrimination

4. Feature Stimulus Classes

   • Have Common Spatial Structures & Common Spatial Arrangements

5. Arbitrary Stimulus Classes

   • Do not share topographical structures or spatial arrangements but they DO evoke the same response

6. Behavior Analysts define stimulus equivalence by testing for:

   • a) Reflexibility
     • b) Symetry
       • c) Transitivity
     • If A=B &
       • B=C, then
         • C=A

7. Matching to Sample is a Four-Term-Contingenycy

   • MO-Antecedent-Bx-Consequence

8. Factors Affecting the Development of Stimulus Control

   • Preattending Skills
   • Stimulus Salience
   • Masking
   • Overshadowing
