The purpose of this study was to examine the unique contributions of (social) cognitive skills such as inhibition, working memory, perspective taking, facial emotion recognition, and interpretation of situations to the variance in social information processing in children with mild to borderline intellectual disabilities. Respondents were 79…

Previous studies by our group suggest that the neuropathology of autism is characterized by a disturbance of cortical modularity. In this model a decrease in the peripheral neuropil space of affected minicolumns provides for an inhibitory deficit and a readjustment in their signal to noise bias during information processing. In this study we…

Dissociation is typically defined as the lack of normal integration of thoughts, feelings, and experiences into consciousness and memory. The present article critically evaluates the research literature on cognitive processes in dissociation. The authors' review indicates that dissociation is characterized by subtle deficits in neuropsychological…

An examination of previous claims for virtually perfect time-sharing in dual-task situations reveals confounding effects that may have obscured dual-task interference. Two experiments are conducted in which these confounding effects are minimized, revealing statistically significant dual-task interference. These results support the hypothesis that…

Interest regarding neural information processing in autism is growing because atypical perceptual abilities are a characteristic feature of persons with autism. Central to our review is how characteristic perceptual abilities, referred to as "perceptual signatures," can be used to suggest a neural etiology that is specific to autism. We review…

Three experiments were conducted to investigate whether semantic information presented to the unattended ear in a dichotic listening experiment has a memory effect after 30 seconds. (Editor)

The present experiment was designed to seek further evidence concerning the possible role of retroactive interference in situations whereby students learn information made available in prose form. (Author)

Two accounts explain why studying pictures reduces false memories within the Deese-Roediger-McDermott paradigm (J. Deese, 1959; H. L. Roediger & K. B. McDermott, 1995). The impoverished relational-encoding account suggests that studying pictures interferes with the encoding of relational information, which is the primary basis for false memories…

Computer modelling research has undermined the view that double dissociations in behaviour are sufficient to infer separability in the cognitive mechanisms underlying those behaviours. However, all these models employ "multi-modal" representational schemes, where functional specialisation of processing emerges from the training process.…

The effect of the repeated presentation of some items in a free-recall list was examined as a function of instructions to recall repeated or unrepeated items first on tests. (Editor)

This paper reviewed briefly the major types of masking effects obtained with various methods and the major theories or models that have been proposed to account for these effects, and outlined a three-mechanism model of visual pattern masking based on psychophysical and neurophysiological properties of the visual system.

Tulving and others (Tulving, 1974; Tulving & Madigan, 1970) have distinguished two kinds of forgetting of verbal information: trace-dependent forgetting and cue-dependent forgetting. Attempts to determine which type occurs in retroactive inhibition of free-recall learning. (Author/RK)

Two experiments tested the hypothesis that proactive interference over a series of Brown-Peterson trials results from a combination of the subject's failure to transfer information to a permanent memory state and failure to retrieve information from permanent memory. (Editor)

Two experiments were performed to investigate the effects of noise-induced arousal on immediate recall of visually presented paired-associate adjectives. (Authors)
