Week 7 Flashcards
Successive Discrimination
Procedure to train differential responding by alternating Sd and Sdelta
(Green light & red light)
Which has least errors
Fading
Successive discrimination?
Fading
Fading
Transferring control of one stimulus (S1) to another (S2) by gradually eliminating S1 in presence of S2
Response prompts (4)
Verbal
Gestural
Modeling
Physical
Stimulus prompt (2)
Within-stimulus prompt (larger/flashing print)
Extra-Stimulus Prompt (separate-arrow directing word)
Types of fading
Prompt Fading (remove prompt to new establishing Sd)
Prompt delay (delaying delivery of prompt)
Stimulus-response chain
Each behaviour in chain produces stimulus change that acts as Sd for next response in chain
Task Analysis
Analyzing beh chain by breaking down to individual stimulus-response components
Chaining procedures
Systematic application of prompting and fading strategies to each stimulus response component in chain
Backward chaining
Used for learners w limited abilities, start with last beh in chain first and physically prompt response
Total task presentation
Complex chain taught as single unit
Graduated guidance
Hand-over-hand guidance, provide less and less assistance as learner completes task
Chaining procedures (7)
Backward Forward Total task presentation Written task analysis Picture prompts Video modelling Self-instructions
Functional assessment
Identifying variables before treating a problem beh
Functional analysis
Experimental methods of conducting functional assessment manipulate antecedent and consequent variables to demonstrate influence on prob beh
