A Piagetian task of spatial functioning and a modified classification problem (simple intersection) were administered to children to test the degree of relationship between logical and sublogical operations by defining their common cognitive components. (Author/DB)

Adults over 50 (n=77) completed Piaget's Three Mountains Task focused on extrapolating others' viewpoints. Performance significantly decreased and egocentric responses significantly increased with age. Three kinds of errors occurred: miscalculations, egocentrism, or complete breakdown of information processing due to task overload. (Contains 19…

Assessed sex differences in performance on the subtests of the Kaufman Assessment Battery for Children using more than 2,500 children ages 2-1/2 to 12-1/2 years old. Results confirmed previous research with female superiority on short-term memory tasks and male superiority on spatial-visualization skills. (Author/ABL)

Three experiments involving 107 adults who performed mental rotation tasks explored how location information is incorporated into image representation. Results suggest that image is coded retinotopically in image representations and that there is no spatiotropic transform in the early stages of visual processing. (SLD)

Investigates whether background television produces structural interference with aspects of cognitive processing. Finds a significant deleterious effect on a geometric analogies and completion task involving visuo-spatial processing and marginal improvement on a parallel verbal analogy test. Shows that concurrent television exposure had no…

Traces a student's use of different types of imagery over an extended period of time in order to determine why the student seldom used imagery to solve problems. Concludes that for most of her school life, the student had been able to rely on analytic processing to complete mathematical tasks and could do so quite successfully. (Contains 30…

This study examined recognition memory for items and their location among adults with Down syndrome (n=24), adults with nonspecific mental retardation (n=22), and community volunteers (n=20). No differences in memory for spatial location were found between the two groups with mental retardation, though both groups performed worse than control…

Presents a case study that aimed to obtain information on students' mathematical comprehension levels and on whether students may or may not make use of visualization processes in solving mathematical problems. Discovers students' beliefs about teaching and learning processes in general, and mathematics in particular. (Contains 25 references.)…

The aim of this article is to show that individuals differ in the way they solve spatial tasks of all kinds, and both research on and measurement of spatial ability could profit from an integration of strategy aspects. We first review evidence for both intra- and inter-individual strategy differences (including gender differences) in 3 domains of…

Attentional allocation in feature-search mode (W. F. Bacon & H. E. Egeth, 1994) is thought to be solely determined by top-down factors, with no role for stimulus-driven salience. The authors reassessed this conclusion using variants of the spatial cuing and rapid serial visual presentation paradigms developed by C. L. Folk and colleagues (C. L.…

We test 3 theories of global and local scene information acquisition, defining global and local in terms of spatial frequencies. By independence theories, high- and low-spatial-frequency information are acquired over the same time course and combine additively. By global-precedence theories, global information acquisition precedes local…

It has been suggested that predictive and bridging inferences are generated at different levels of text representation: predictive inferences at a reader's situation model and bridging inferences at a reader's propositional textbase (Fincher-Kiefer, 1993, 1996; McDaniel, Schmalhofer, & Keefe, 2001; Schmalhofer, McDaniel, & Keefe, 2002). Recently,…

This paper studies the dynamics of attempting to access two spatial memories simultaneously and its implications for the accuracy of recall. Experiment 1 demonstrates in a range of conditions that two cues pointing to different experiences of the same object location produce little or no higher recall than that observed with a single cue.…

It has been found that disoriented children could use geometric information in combination with landmark information to reorient themselves in large but not in small experimental spaces. We tested domestic chicks in the same task and found that they were able to conjoin geometric and nongeometric (landmark) information to reorient themselves in…

An important characteristic of mature spatial cognition is the ability to encode spatial locations in terms of relations among landmarks as well as in terms of vectors that include distance and direction. In this study, we examined children's use of the relation "middle" to code the location of a hidden toy, using a procedure adapted…
