In Thorndikian experiments, Ss have performed better on Trial 2 when they were told whether Trial 1 responses were right or wrong on Trial 2 than when given this information immediately after each response on Trial 1. Authors reexamined these experiments. (Editor/RK)

The effects of instructions to use imagery, sentence, or repetition strategies were compared on original learning, negative transfer, retroactive interference (RI), and 48-hr. retention. (Editor)

The present experiment was designed to investigate the role of the PA test trial by use of a design in which the testing phase of a series of PA recall trials was deleted and replaced on each of the trials by a computational procedure. (Author)

In the present study, and attempt was made to clarify whether right visual field superiority, in terms of shorter latencies to verbal material, transcends the directional scanning tendencies associated with the stimuli. (Author)

Laboratories using animals were evaluated for their contribution to learning processes of students in introductory psychology courses. (RK)

In this paper, a black psychologist shares his thoughts, biases, and educated guesses pertaining to experimental psychology as it might relate to the psychoeducational needs of Afro-American children. First, some of the assumptions embodied in the empirical research enterprise are examined. It is noted that empirical research is a tool for gaining…

To investigate the possible cue (stimulus) as opposed to motivational functions of drive and reward, this study assessed the effects of problem difficulty, reward magnitude, and drive level on the performance of rats in visual discrimination tasks entailing both choice and speed measures. (Editor/RK)

In the present study an attempt was made to investigate the duality of encoding mechanisms via instructional sets that were independent of stimulus characteristics. (Author)

To investigate human visual identification of different-sized objects as identically shaped, matching reaction times were measured for pairs of simultaneously presented random figures. (Editor)

This article examined the effect of allocation of attention on adaptation to displacement when proprioception and vision conflict and considered whether more effective procedures to insure that attention is directed in the prescribed manner would cause adaptation to be confined strictly to the unattended modality. (Author/RK)

Studies employing schematic faces of three features explored the role of the left hemisphere as an analytic processor in difficult discriminations and the role of the right hemisphere in easy gestalt matches. (Editor)

The following experiments are an attempt to clarify the role of learned safety by investigating the applicability of the concept of conditioned inhibition to a taste-aversion procedure and by differentiating its effects fromthose of latent inhibition. (Author)

Two experiments employed an incidental learning paradigm to assess mnemonic control processes. (Editor)

The question under investigation in the present paper is whether subjects can effectively use retention interval information under demanding acquisition and retention conditions, specifically, to evaluate the contribution of retention interval information to memory performance when temporal information is made explicitly available. (Author/RK)

Four experiments examined the effect of label training on redintegrative memory for novel shapes (remembering the whole shape when only a part is presented). (Editor)
