Document Summary
Instrumental conditioning leaning of contingency between behavior and consequence. Edward l. thorndike studying cats in puzzle boxes and recorded escape time. Predicted after the first time, cats would immediately escape. Frequency of random behaviours gradually decreased over time stimulate-response process for little credit for consciousness no ah-hah moment like humans. Stamping in and stamping out behaviour maintained or eliminated. Law of effect behaviours with positive consequences are stamped in. Reinforcer stimulus that, when presented after a response, leads to change in rate of that response. Effectiveness of reinforcement affected by time between behaviour and consequence reinforced shorter=more effective. Acquisition organism learns contingency between stimulus and biological important event. Cumulative recorder measures response rates: flat horizontal line not responding, diagonal response made, rate depends on subject, type of reinforcement used, complexity of behaviour. Autoshaping learn contingency without careful guidance, doesn"t work for complex used, etc behaviours.
