Facilitated Learning

An experiment designed to specify the process similarities of information feedback and reinforcement and to note the interaction of 2 major feedback variables on a simple positioning task. 80 students were randomly divided into 4 groups receiving either 25, 50, 75, or 100% schedules of feedback, analogous to fixed-ratio schedules of reinforcement. The 4 groups were further divided into 2 subgroups that differed in terms of specificity of feedback. Results indicated that when all Ss were provided the same number of feedbacks, the groups did not differ during acquisition. Groups with partial information feedback demonstrated greater resistance to extinction. The coarse-scale treatment facilitated learning but had no effect during extinction. There was no interaction between frequency and specificity of information.

Random Ratio

Variable and random ratio schedules of reinforcement are conceptually contrasted and experimentally compared in a computer simulated “slot machine” task. 20 subjects did not behave differentially in terms of either choice of game or employment of strategy.

Resistance To Extinction

An interpretation of the effects of overtraining on resistance to extinction, in terms of differences in frustration, is called into question by the extinction behavior of Ss trained or overtrained with different schedules of reinforcement.

Mild Punishment

4 male, chronic schizophrenic inpatients were subjects in an experiment aimed at investigating whether contingent verbal reinforcement could decrease delusional verbalizations. The reinforcement connoted both approval and mild punishment, and two different schedules of reinforcement, fixed and variable ratios, were employed. A significant conditioning effect was observed, but neither fixed ratio nor variable ratio was successful in providing resistance to extinction. Results were discussed in the light of the immediacy hypothesis which suggests that immediate stimuli govern the behavior of schizophrenics.

Gaming Machines

The distribution of rewards in both variable-ratio and random-ratio schedules is examined with specific reference to gambling behaviour. In particular, it is the number of early wins and unreinforced trials that is suggested to be of importance in these schedules, rather than the often-reported average frequency of wins. Gaming machine data are provided to demonstrate the importance of early wins and unreinforced trials. Additionally, the implication of these distributional properties for betting strategies and the gambler's fallacy is discussed. Finally, the role of early wins and unreinforced trials is considered for gambling research that utilises simulated gaming machines and research that compares concurrent schedules of reinforcement.
