Spatial ability predicts success in STEM (Science, Technology, Education, and Mathematics) fields, particularly chemistry. This paper reports two studies investigating the unique contribution of mental rotation ability to spatial thinking in a STEM discipline. Using authentic disciplinary tasks from chemistry, we show that the difficulty of a…

Spatial skills include the creation of objects in the mind and visualization them from different angles. This study examines the impact of Google SketchUp program on the development of mental rotation skills from spatial skills of eleven-year-old students. The study was conducted as a mixed method research. The quantitative research method of the…

The visual imagery of four individuals with blindness was compared with that of five sighted individuals using the detection of mirror symmetry. The two participants who lost their sight later in life outperformed the two with congenital blindness, indicating the importance of early visual experience in visual imagery. (CR)

Individual difference variables that are potentially related to cognitive mapping skills were examined, and good and poor cognitive mappers were compared in terms of those variables. Good and poor cognitive mappers were identified on the basis of the accuracy of their spatial knowledge about their own community. Four categories of individual…

The information-processing approach and results of research on spatial ability are analyzed. Performance consists of a sequence of distinct mental operations that seem general across subjects, and can be individually measured. New interpretations for some classical concepts in psychological testing and procedures for abilities are suggested.…

Two correlational investigations attempted to establish the construct validity of the dimensions assessed by the Inventory of Learning Processes scales. The scales are Synthesis-Analysis; Study Methods; Fact Retention; and Elaborative Processing. A number of cognitive tests were also administered. (MH)

An aptitude-strategy interaction in linear syllogistic reasoning was tested on 144 undergraduate and graduate students of both sexes. It was hypothesized that the efficiency of each of four alternative strategies--control, visual, algorithmic, and mixed--would depend upon the subjects' pattern of verbal and spatial abilities. Two tests of verbal…

This report is part of a general study of Reference Measures for Cognitive and Noncognitive Factors. The main activity being reported is the development of "factor-referenced" or "marker" tests for several recently identified cognitive factors. A secondary activity involves the study of possible relationships to factors already…
