Despite evidence for the involvement of working memory in mathematics attainment, the understanding of its components relationship to individual areas of mathematics is somewhat restricted. This study aims to better understand this relationship. Two-hundred and fourteen year 3 children in the UK were administered tests of verbal and visuospatial…

Visual and auditory verbal learning using a selective reminding format was studied in a mixed clinical sample of children with autism spectrum disorder (ASD) (n = 42), attention-deficit hyperactivity disorder (n = 83), velocardiofacial syndrome (n = 17) and neurotypicals (n = 38) using the Test of Memory and Learning to (1) more thoroughly…

This study explored the relative strength of five neuropsychological tests in correlating with productivity 1 year after traumatic brain injury (TBI). Six moderate-to-severe TBI patients who returned to work at 1-year post-injury were matched with six controls who were unemployed after 1 year based on age, severity of injury, and Functional…

Because of ongoing neuromaturation, youth with chronic alcohol/substance use disorders (AUD/SUD) are at risk for cognitive decrements during young adulthood. We prospectively examined cognition over 10 years based on AUD/SUD history. Youth (N = 51) with no AUD/SUD history (n = 14), persisting AUD/SUD (n = 18), or remitted AUD/SUD (n = 19) were…

Asperger syndrome (AS) and non-verbal learning disability (NLD) are both characterized by impairments in motor coordination, visuo-perceptual abilities, pragmatics and comprehension of language and social understanding. NLD is also defined as a learning disorder affecting functions in the right cerebral hemisphere. The present study investigates…

Williams syndrome (WS) is a neurodevelopmental genetic disorder often described as being characterized by a dissociative cognitive architecture, in which profound impairments of visuo-spatial cognition contrast with relative preservation of linguistic, face recognition and auditory short-memory abilities. This asymmetric and dissociative cognition…

Those who focus on the study of visual information continue to search for effective ways to conceptualize that inquiry. However, many visual examples are better categorized as visual/verbal collaboration, complicating analysis. When analysis is based on the assumption that visual and verbal modalities perform in similar ways, important…

The hypothesis that describing a visual memory can result in recoding interference was investigated in a series of 6 experiments with 518 college students. Collective results were consistent with the hypothesis; verbalizing memory can produce a verbally biased memory representation that can interfere with the original visual memory. (SLD)

Evidence supports the hypothesis that visual word recognition may involve recoding into phonemic form. Less pronounceable nonsense words are recognized as nonsense faster than those more pronounceable. Differences in pronounceability may produce their effects during sequencing of neural instructions of each phoneme. (CHK)

This contradicts N. F. Johnson's arguments that word perception does not follow letter perception and that letter analysis awaits identification of the word as a unit. His experiments lack controls, and uncontrolled factors may contribute to his effects. Johnson's implications for prior-letter-processing models are contradicted. (CHK)

Two experiments explore the activation of semantic information during spoken word recognition. Experiment 1 shows that as the name of an object unfolds (e.g., lock), eye movements are drawn to pictorial representations of both the named object and semantically related objects (e.g., key). Experiment 2 shows that objects semantically related to an…

Describes an experiment measuring response latency which required subjects to make a word-nonword decision in response to a visually presented item. (AM)

Experimental conditions consisting of visual experience, visual plus motor training, visual plus verbal-orienting instruction, visual plus motor plus verbal, and a control group were used to study young children's concept development. Assessment was based on discriminating and remembering positive concept instances and classifying concept…

A previous study by Gibson et al. (1972) that investigated the effect of orthographic structure on letter search was replicated and extended in order to identify factors that might explain the apparent discrepancy between their results and those of comparable studies. Experiment one tested whether the discrepancy might be explained by difference…

This paper reports on a study concerned with rapid mental operations of the central processor as it performs tasks such as the comparison of rotated figures, mental arithmetic, sentence verification, and memory scanning. The central processor is the site of most of the symbol manipulation that takes place in the human information processing…
