Data were interpreted as suggesting that incidental learning may not be cumulative over trials, but rather, may be due to memory of the last trial. (Author)

Results of these experiments are evaluated in conjunction with the hypothesis that frequency information is a dominant attribute in recognition decisions. (Author/MB)

Investigates the effect of delay of reinforcement upon human discrimination learning with particular emphasis on the form of the gradient within the first few seconds of delay. In previous studies subjects are usually required to make an instrumental response to a stimulus, this is followed by the delay interval, and finally, the reinforcement…

In this study, 48 third-grade children learned a successive, two-choice discrimination under one of three conditions: (1) immediate reinforcement (IM), (2) 10-second empty delay (ED), and (3) 10-second delay with the discriminative stimuli in view of S (FD). The performances of groups IM and FD were only marginally different, and were both…

Article focuses on three issues in verbal discrimination learning: effect of list length, effect of the study-test method as opposed to the anticipation procedure, and transfer and retroactive effects when the interpolated task consists of a reversal of the right and wrong functions of the members of the pairs. (Author/ML)

Efficiency was compared between three procedures for sequencing examples with minimal stimulus variation between adjacent positive and negative examples: dynamic, static, and static with maximal differences between pairs. For young children, increasing relevant feature saliency and altering a single stimulus to generate examples reduced training…

The present experiments investigated the effects of several classical conditioning manipulations on the performance of young children in an instrumental discrimination learning situation. Two predictions from general conditioning-extinction theory were tested: (1) acquisition of an instrumental response to a stimulus for a positive reinforcer in a…

Thirty subjects were presented with a visual form discrimination task requiring them to match Roman letters when a variety of transformations were held constant. They were given massed practice across four blocks of eight stimuli. Results of a repeated measures analysis of variance showed support for the distinctive features hypothesis. (JC)

Experiment was concerned with the validity of the assumptions involved in the proposal of some minor modifications in the frequency theory of verbal-discrimination learning. (Author/CB)

Results indicate that the RCR (rehearsal-of-the-correct-alternative response) plays an important role such that when the RCR is inhibited, performance is reduced. (Authors/CB)
