Effects Of Delay And Signals On Choice Between Delayed Food Alone And Immediate Food With Delayed Shock, Forrest James Toegel
Effects Of Delay And Signals On Choice Between Delayed Food Alone And Immediate Food With Delayed Shock, Forrest James Toegel
Graduate Theses, Dissertations, and Problem Reports
Much of the research in the area of self-control has examined choice between small immediate reinforcers and large delayed reinforcers, but many problems result from situations in which a single choice produces consequences of conflicting valence: Those in which the immediate outcome is reinforcing and the delayed outcome is aversive. Recent research has evaluated how preference for a large reinforcer which is followed by a delayed shock changes as a function of the delay to shock and how the intensity and duration of delayed shock affects the value of a large reinforcer. The present set of experiments investigated how the …
Effects Of Reinforcement Rate On The Aversive Function Of Timeout From Positive Reinforcement, Cory Whirtley
Effects Of Reinforcement Rate On The Aversive Function Of Timeout From Positive Reinforcement, Cory Whirtley
Graduate Theses, Dissertations, and Problem Reports
Although the use of timeout from positive reinforcement is widespread and has been shown to be an effective punisher in clinical settings, the factors responsible for its effectiveness are not fully understood. The present experiment was designed to evaluate one of these factors, the reinforcement rate underway during periods of time-in. Rats’ lever pressing was maintained on variable-interval schedules of food reinforcement in a multiple schedule with two components. In one component, no timeouts were delivered. In the other component, when a variable-ratio schedule was met, lever presses were followed by a 30-s timeout during which a tone sounded, the …
