The performance of 19 autistic children on an object discrimination learning set task was compared with that of mental-age and IQ matched control groups of normal and retarded children. (Editor)

The purpose of this study was to evaluate the process of change within a construct as it undergoes either weakening by invalidation or strengthening by validation. Furthermore, this process was considered in terms of affective versus nonaffective constructs in order to determine whether invalidated affective constructs are more subject to…

Two different experimental procedures were used to examine (a) information-processing differences between two groups of subjects (Cs versus Vs) identified by the form of their conditioned eyeblinks; (b) information-processing differences between the right and left cerebral hemispheres; and (c) parallels between hypothesized C-V differences and…

This paper discussed two probe techniques (blank trials and introacts) in explorations of problem solving by adults and children. The implications for H (hypothesis) theory, developmental theory, and developmental research are also discussed. (Editor/RK)

Two experiments tracked the acquisition of skilled reading as college students read as many as 160 pages of geometrically inverted text and assessed the consequence for memory of skill at reading. Results were interpreted in terms that emphasized an operational basis to memory--pattern-analyzing procedures rather than conscious contents.…

Recently, Nilsson (1975) challenged Watkins's conclusion that the modality effect is a post-categorical phenomenon. In this brief reply the authors argued that Nilsson's findings are not only consistent with the postcategorical interpretation but also inconsistent with the precategorical interpretation.

Determination of the role of input cues in free recall and clarification of the reduction effect of cued input on free-recall performance are of importance for any theory dealing with encoding and retrieval. It is these two issues which are the primary focus of the present experiment. (Author)

The results of this experiment suggest that requiring subjects to simultaneously suppress subvocalization and remember syllables depresses performance slightly, but encoding of speech sounds in short-term memory occurs independently of subvocal activity during the memory task. (Editor/RK)

Authors questioned whether the familiarity effect in the processing of words is a "perceptual" phenomenon or whether it is produced by visual rather than verbal mechanisms. (Author/RK)

The experiments reported here investigate the effects of different kinds of set on hemisphere differences, and confirm that, in some conditions, the hemispheric asymmetry in a particular task may shift when cuing establishes an attentional set. (Author)

Three models are proposed to describe the strategy applied by a subject when he is confronted with two successive time intervals and is required to deal with some relation between them, for example, by telling which was the longer by adjusting the second to match the first. (Author)

To what extent does prior knowledge of a superordinate category facilitate recognition of an instance of that category? The results of this study reveal that the facilitating effect of a category prime on perceptual processing is inversely related to the quality of the stimulus information available. (Author/RK)

Attention has recently been drawn to experiments on the extent to which items can be recalled and recognized, and the overall level of recognition. A model proposing both direct-access and generation-recognition mechanisms in recall is shown to provide a satisfactory account of the phenomenon. (Editor)

Although epidemiological data have documented sex differences in depression, the nature and origins of the differences are unclear. Depression in a large sample of young, unmarried college students was measured and described by the Beck Depression Inventory. Considers the consequences of sex differences in depressive responses, including…

Attempts to demonstrate performance impairments following exposure to an uncontrollable event, to investigate the effects of such exposure on mood, and examines the question of cross-situational generality of the induced impairments. (Author/RK)
