The ability to decide rapidly that two visual stimuli are nominally the same when they are also visually the same (the Posner effect) was examined for stimuli of increasing visual complexity (Experiment 1) and when a greater variety of visual differences between the two stimuli was employed (Experiment 2).

Three experiments evaluated the effect of poststimulus distractor characteristics in altering recognition of random shapes. (Editor)

The present experiment measured the effects that shadowing (repeating aloud) a series of aurally presented items has on the reading process. (Author/RK)

Three experiments contrasted subjects' memory for verbal and figural displays. Data are discussed in terms of a multiple coding model, which is suggested as a more fruitful approach than single-code models such as those proposed by Pylyshyn or Anderson and Bower. (Editor/RK)

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)

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)

The ability of preverbal infants to abstract a prototypical representation of a category, when presented with examples of an artifically constructed category, was investigated. It was determined that infants could process visual information constructively and could take a more active role in category formation than previously believed. (Author/MH)

The Peterson and Peterson short-term memory paradigm (1959) involves an interpolated task with several potential dimensions from which interference may originate: similarity of items and vocalization. This research assesses the relative interference potency of each on material presented either aurally or visually. (Editor/RK)

Memory trigrams were presented by one of three methods: visual-concurrent (all three letters appeared simultaneously), visual-successive, and auditory-successive. (Editor)

These experiments show two things: (a) In visual memory, long-term interference on a current item from items previously stored only seems to occur when the current item's retention interval is relatively long, and (b) the visual code appears to decay rapidly, reaching asymptote within 3 seconds of input in the presence of an interpolated task.…

The extent to which an orienting activity exerts control over the encoding process was studied. Two experiments were reported in which associative meaningfulness was varied under conditions of semantic and nonsemantic processing. Both experiments showed effects of meaningfulness following both semantic and nonsemantic tasks. (Author/MH)

The original impetus for this work was to characterize the extent to which olfactory experience can be incorporated into cognitive processes. The finding is that there is a respectable but limited verbal association learning and retention capability for odor stimuli in man. (Author)

A multirate mathematical model is presented to support the hypothesis that different types of information are lost from a memory trace at different rates. The model is validated by two experiments assessing the retention of pictures and of sentences at three different delays by cued recall. (Author/CP)
