Studies the perceptual relationship between temporal "before" and "after" and their spatial counterparts. Adults reported temporal "before" related to spatial "after" and temporal "after" related to spatial "before." Three-year old children better understood spatial "after" and spatial "before," suggesting a temporal/spatial semantic acquisition…

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.

Several experiments were undertaken with a total of 111 undergraduates. Subjects attempted to imagine how three-dimensional novel wire objects would appear from viewpoints other than that of the subject. Subjects were unable to perform this task without making use of strategies that circumvent the process of visualization. (TJH)

In experiments involving 178 and 190 military recruits, spatial, quantitative, and verbal inspection time (IT) and visual search (VS) tasks and an intelligence test were administered. Results indicate that IT performance has a component related to intelligence tests and an independent component related to processing speed tests such as VS. (SLD)

Reports findings from three experiments designed to show how readers inferred spatial information relevant to a story character's movements through a previously memorized layout of a fictional building. Examines how inference measures are related to spatial imagery. (HB)

Two experiments examined the development of recall organization by observing use of categorical and spatial clustering strategies and how encoding experiences and recall task influence degree of organization. Children and adults recalled furniture from their home. Older subjects organized items spatially; when recalling objects and their…

Three age groups of 24 people each completed verbal word list tasks and spatial learning tasks 5 times each. Significant age differences were found for total recall and type of task. Younger subjects showed increased levels of clustering--organizing information according to semantic or spatial clusters. Age was not related to temporal order of…

Opens with the theoretical construct of figural concepts. Argues that geometrical figures are characterized by both conceptual and sensorial properties. Investigates the effects of interaction between conceptual and figural components. Contains 19 references. (DDR)

Suggests that scientific thought experiments (TEs) draw upon three epistemological resources: conceptual-logical inferences, visual imagery, and bodily-motor experience. Argues that TEs are powerful because of students' thought capabilities related to imagination and visual imagery. Claims that TEs are not currently exploited by school learning…

Reviews selected literature on child development about children's symbol use in performance of spatial and mathematical tasks. Describes the musical development of a child over a period of 16 months and shows how principles of symbol use from outside music can guide interpretations of children's symbol acquisition. (CMK)

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…

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…

In the present study, a systematic comparison of sex differences for several tests of spatial memory was conducted. Clear evidence for more accurate male performance was obtained for precise metric positional information in a wayfinding task and in an object location memory task. In contrast, no sex difference characterized topological information…

This article examines how the human visual system represents the shapes of 3-dimensional (3D) objects. One long-standing hypothesis is that object shapes are represented in terms of volumetric component parts and their spatial configuration. This hypothesis is examined in 3 experiments using a whole-part matching paradigm in which participants…
