systematic and differentially reinforces successive approx. to a terminal behavior. Acquire new behaviors
2 components-differentially reinforce behaviors that resemble the terminal behavior. Carefully changing the criterion for reinforcement-increase in desired bx and decrease in non terminal bx
Dimensions of behavior that can be shaped
topography (form), frequency, latency, duration, amplitude
An intermediate behavior. Prerequisite to terminal behavior...same response topography
Shaping across topographies
across topography of behavior changes during shaping. Still members of the same response class
Shaping within topographies
Topography of behavior remains constant. Another measurable dimension is changed (duration, latency)
Cons of shaping
can be time consuming, progress isn't always linear and may be erratic, requires a skillful trainer, can be misapplied...can accidently shape harmful behaviors
shaping vs. fading
both change behavior gradually. fading is antecedent...shaping changes response requirements
Guidelines for shaping
what is behavior and how far are we from it? How long will it take? what is the availability of staff and resources
Must define terminal behavior before shaping
look at response class...know what approximations are part of the behavior....
