Five experiments involving a total of 44 college students addressed the effects of intercomponent consistency on skill acquisition in a class of cognitively demanding tasks requiring rapid integration of information and rapid application of rules. The role of consistency of external stimulus-to-rule linkage in facilitating learning and performing…

Tests of spatial ability that were designed to minimize the effects of sociocultural expectations on performance were administered to adults of both sexes. The tests examined spatial problem-solving, spatial memory, and psychomotor spatial performance, as measured by three "throwing tasks." Thirty-four male and 34 female university…

Although metamemory has recently received renewed interest by several investigators, individual differences in memory skills have received little if any attention. While individual differences in memory skills have common sense validity, these differences have been difficult to document experimentally. This study used a repeated measures design to…

Results indicated a significant difference between the 18 normal readers and the 36 learning-disabled readers on tasks matching auditory temporal to visual-spatial and auditory-temporal to visual-temporal but not on the visual-temporal to visual-spatial task. Results were interpreted in terms of learning-disabled readers being deficient in…

A discussion is given concerning possible interactions of balance with spatial ability and M-space, i.e., the span of short-term memory. Thirty graduate statistics students were the subjects in an investigation that revealed a sizable Balance by spatial by M-space triple interaction. (Author/AH)

Spatial span (Corsi's block tapping) and verbal span (Wechsler Digits Forward) were measured in 1113 children (ages 4-10) from urban and rural districts of Italy. The urban group performed significantly better on both tests. Sex differences, favoring boys, were found only on the spatial span test. (Author/SJL)

No age difference was observed on the temporal task, but older adults performed worse on the spatial task. Results indicate normal aging is not associated with poor encoding or retention of all types of information, but affects retention of some information often assumed to be encoded automatically.

Measured cognitive processing time, imagery skill, and spatial memory span of 128 children and adults, ages 8 to 20 years. Found that performance on spatial memory span tasks was largely predicted by imagery skill, which in turn was strongly linked to processing time; age was much less of a predictor in both cases.

This study investigated the tendency of deaf children (ages 6-13) not to spontaneously use active memory strategies such as rehearsal. Comparison of 38 deaf and 39 hearing students found that deaf students compensated for less effective rehearsal strategies by capitalizing on unique spatial features of the task. (Author/DB)

A study investigated the relationship between working memory (WM), declarative strategy knowledge, and math achievement in 111 children with and without mathematical disabilities (MD). Results found verbal and visual-spatial WM, stable verbal strategy choices, and expert strategy choices related to visual-spatial processing all contributed…

Objective: Deficits in executive functioning, including working memory (WM) deficits, have been suggested to be important in attention-deficit/hyperactivity disorder (ADHD). During 2002 to 2003, the authors conducted a multicenter, randomized, controlled, double-blind trial to investigate the effect of improving WM by computerized, systematic…

Individuals' mental maps of the world are highly misrepresentative of the actual world. Availability in memory partly explains the reasons for this misrepresentation. When asked to place the 50 states in their correct locations, students have difficulty with states not in close proximity to their own because of availability, such that the…

The purpose of the present study is twofold: the first objective is to evaluate the importance of visual experience for the ability to form a spatial representation (spatial mental model) of fairly elaborate spatial descriptions. Secondly, we examine whether blind people exhibit the same preferences (i.e. level of performance on spatial tasks) as…

Background: The study is concerned with the cognitive abilities of children with specific language impairment (SLI). Previous research has indicated that children with SLI demonstrate difficulties with certain cognitive tasks despite normal non-verbal IQ scores. It has been suggested that a general processing limitation might account for the…

A latent-variable study examined whether verbal and visuospatial working memory (WM) capacity measures reflect a primarily domain-general construct by testing 236 participants in 3 span tests each of verbal WM. visuospatial WM, verbal short-term memory (STM), and visuospatial STM. as well as in tests of verbal and spatial reasoning and general…
