Recent methodological advances have allowed researchers to address confounds in the measurement of task-switch costs in task-switching performance by dissociating cue switching from task switching. For example, in the transition-cuing procedure, which involves presenting cues for task transitions rather than for tasks, cue transitions (cue…

Comments on a study by Schacter and others which proposes that insights into why infants make the AB error can be gained by examining the errors of brain-damaged adults on similar tasks. (The B in AB has a line over it in the title and in the article meaning "A not B.") (PCB)

This study explored the ability of 14 individuals with autism to generate a unique series of digits. Individuals with autism were more likely to repeat previous digits than comparison individuals, suggesting they may exhibit a shortfall in response inhibition. Results support the executive dysfunction theory of autism. (Contains references.)…

Causal reasoning represents one of the most basic and important cognitive processes that underpin all higher-order activities, such as conceptual understanding and problem solving. Hume called causality the "cement of the universe" [Hume (1739/2000). Causal reasoning is required for making predictions, drawing implications and…

The study evaluated the semantic system of mentally retarded adults (N=32) to determine whether they encode information in semantic memory on the dimensions of item prototypicality and list organization. Results suggested that interference effects inhibited encoding by organization and typicality. (DB)

Three variables (diagnosis, location of cues, and mental age of learners) influencing stimulus control and stimulus overselectivity were assessed with eight autistic children (mean age 12 years) and eight average children matched for mean age. Among results were that autistic subjects tended to respond overselectively only in the extra-stimulus…

Emphasizes the social and interpersonal aspects of actions, especially as described in Soviet psychology. Argues that remembering is essential for intentional action. Intentional action is derived from the communication and cooperative relations between two people. (RH)

Analyzes the intentionality of conceptually mediated perception and explicates a conception of immediate perception and its intentionality. The model of immediate perception is applied to studies of infant perceptual capacities in the first months of life. Prefigurations of the categories of object, identity, existence, permanence, and…

Presents evidence relevant to three models of the way young children perform N-term series tasks: the labeling model, the sequential-contiguity model, and the ordered array or image model. Reexamines children's ability to learn sets of premises which can be assembled into an ordered array. Participating were children three to seven years of age.

Assesses children's recall performance using three memory instructions: standard free recall, repetition, and categorical processing. Recall performance was about equal for standard versus repetition and superior when category processing is used, especially with highly representative items. Concludes that at both 7 years and 10 years the…

Infants' detection of temporal increments to silent intervals "between" groups of tones was compared with their detection of comparable silent increments "within" groups of tones. Results indicated infants discriminated temporally altered sequences from standard only when increments occurred within group. Concludes perceptual…

This study examined the performance of 23 tinnitus patients on three versions of the Stroop color-word test. Results showed that tinnitus patients performed significantly slower than controls on all test conditions. Results suggest that tinnitus patients have impaired cognitive performance overall, possibly confounded by hearing impairment.…

The specificity of memories has been identified as a factor affecting reality monitoring performance. To examine the reality monitoring model of Johnson and Raye (1981) and to explore the relationship between memory specificity and reality monitoring, the amount of cognitive operations involved in processing information was manipulated for 72…

Recently, interest in research measuring stream of consciousness or thought has increased. A study was conducted, based on a previous study by Hurlburt, Lech, and Saltman, in which subjects were randomly interrupted to rate their thoughts and moods on a Likert-type scale. Thought samples were collected from 27 subjects who carried random-tone…

Tested the model which posits that heart-rate deceleration and respiratory sinus arrhythmia are indices of infant attention. Infants studied cross-sectionally at 14, 20, and 26 weeks of age were presented with complex patterns on a TV screen which were accompanied by an "interrupting stumulus". (Author/BN)
