Three reaction time (RT) experiments using a modified Strenberg procedure were conducted to determine the number of memory representations maintained for perceptual (dot-pattern) concepts. (Editor)

Older individuals have been reported to use imagery mediation less in remembering verbal material. To determine whether this is due to decrease in the speed with which verbal stimuli are recoded into pictorial representations, the reaction time of 12 old (63-78) and 12 young (17-25) subjects for matching verbal descriptions to geometric shapes was…

The results of four experiments show that (a) recall superiority over recognition is reversed by the use of unrelated word pairs in the study list, and (b) the reversal of recall superiority leaves intact the phenomenon of recognition failure of recallable words. (Editor)

Investigates the effectiveness of cues and the differences between cued-recall and free association tasks. (Author/RK)

If half of the items in a list are repeated over a series of trials while the remainder of the items are new on each trial, recall of the repeated items is impaired. Two experiments examined the list context effect and a list differentiation interpretation was supported. (Editor/RK)

Recent research has suggested that the use of the shift effect as a measure of encoding is critically dependent upon its properties as a psychological phenomenon. Examines this interrelation in light of data from a simple experiment. (Author/RK)

Three converging procedures were used to determine whether pictures presented in a rapid sequence at rates comparable to eye fixations are understood and then quickly forgotten. (Editor)

Tulving and Thomson's encoding specificity effect was examined as a function of grammatical class and concreteness of the cues. (Editor)

Five experiments are described which examine how polysyllabic words are stored and retrieved from lexical memory. The first four experiments look at interference effects caused by the accessing of inappropriate lexical entries. The fifth reveals that frequency of the first constituent of a compound word influences classification times. (CHK)

Evidence for the hypothesis that the appearance of visually presented words is stored in "literal copy" form is critically evaluated and shown to be inconclusive. An experiment in which students were required to retain information about zero, one, or two visual properties of words is reported. (Editor)

The present research represents an initial attempt to compare the results obtained using artificial information with results obtained in a typical semantic memory experiment. (Editor)

The effects of vocalized tests on paired-associate learning were compared with those of silent tests and of blank trials by using six conditions, each repeating a pattern of six cycles including one study trial. (Editor/RK)

Two studies (1) compared the ability of pre- and post-operational children to seriate sets of 4 temporal sequences presented simultaneously and (2) examined the ability to recall sequences when given the initial, middle, or terminal item as a retrieval cue. (SB)
