Document Summary
Chapter 10 aversive control: avoidance and punishment. Individual has to make a specific response to prevent an aversive stimulus from occurring. Negative contingency between instrumental response and aversive stimulus. Active avoidance (achieving increasing periods of safety by doing something) No pleasures are derived from these experiences. Grab a handrail to avoid slipping or take an umbrella to avoid getting rained on. Proved that avoidance conditioning is different from standard classical conditioning. Method similar to the one used by brogden. Discriminated or signaled avoidance involves discrete trials. Each trial is initiated by the warning signals or cs. Events that occur after depend on what participant does. Subject makes target response before the shock is delivered. = cs is turned off and us is omitted (successful avoidance trial) Subject fails to make required response during cs-us interval = shock appears and remains on until the response occurs (escape trial) During early stages of training, trials are usually escape.
