WISC subtest scores from two populations of disabled readers were factor analyzed. Sub tests included in Bannatyne`s Spatial and Conceptual categories were each found to comprise separate factors. Subtests in Bannatyne's Sequential category, particularly Digit Span and Coding, comprised a separate factor in only one of the two populations. This suggests that the lowered scores of disabled readers on Digit Span and Coding cannot be accounted for in terms of a single underlying short-term memory ability.

    Inattentional blindness (IB) occurs when an observer, who is engaged in a resource-consuming task, fails to notice an unexpected although salient stimulus appearing in their visual field. The incidence of IB is affected by changes in stimulus-driven properties, but little research has examined...

    To look successively at sites where several spots of light have appeared in the dark, we cannot simply rely on the image left by these targets on our retina. Our brain has to update target coordinates by taking into account each gaze movement that has taken place. A particular type of brain cell...

    Visual short-term recognition memory for multiple stimuli is strongly influenced by the study items' similarity to one another�that is, by their homogeneity. However, the mechanism responsible for this homogeneity effect has remained unclear. We evaluated competing explanations of this...

    When two targets are embedded in a temporal stream of distractors, second-target identification is initially impaired and then gradually improves as inter-target interval lengthens (attentional blink; AB). Notably, in about half of the published studies, this deficit is partially ameliorated...

    Although research has demonstrated that children with specific language impairment (SLI) and reading disorder (RD) exhibit sustained attention deficits, no study has investigated sustained attention in children with speech sound disorder (SSD). Given the overlap of symptoms, such as phonological...
