Space perception is necessary for work in branches of technology from the machine industry to civil, electrical, and material engineering. The spatial perception of students coming to technical universities is not highly developed. There are several reasons for this unfortunate situation: firstly, the lack of emphasis put on geometry and other…

This paper presents a collection of thoughts and observations about a grand theory of creativity in the arts. The theory elaborated in the paper is based upon the following five major bodies of psychological knowledge and research: (1) hemisphere differences and cerebral lateralization; (2) chemical balance in the brain and bipolar factors; (3)…

An Ames static trapezoidal window was used to test infants' responsiveness to pictorial depth. Sensitivity to the pictorial information for depth that is present in the trapezoidal window appears to develop after the age of 22 weeks. (Author/DB)

Replicates a study of spatial egocentrism in Thai 5- to 7-year-old children, using a sample of 4- to 8-year-old Australian children. (Author/CM)

In two experiments, undergraduates did/did not create a maplike representation while learning a passage, and were either forced to study the map, instructed to study, or given no map prior to reading. Free-recall data showed that forced map study benefited learners with low vocabulary scores. (Author/GK)

Used two spatial and language tasks to investigate that clockwise directionality in circle drawing indicates neutral integration difficulties. Tasks were administered to 106 children, eight years of age. Data were analyzed for sex differences and circling behavior. None of the hypotheses based on Blau's theory was supported. (Author)

Indicates that spatial ability describes a variety of different behaviors and briefly reviews efforts to define intelligence factors and identify processes involved in solving tasks requiring spatial ability. (DS)

Analysis of 116 students revealed those who preferred to process mathematical information by verbal-logical means outperformed more visual students on tests. Spatial ability and knowledge of spatial conventions had less influence on performance than expected. (MP)

First-, fifth-, and eighth-grade children were asked to make bearing and distance estimates to six targets from three sighting locations in their school. Among the results, correlations between estimated and actual bearings and distances were extremely high at all grade levels. Bearing accuracy increased between first and fifth grades. (Author/RH)

Children's performances in pointing a telescope at landmarks surrounding their own neighborhood were assessed for 60 children in three age groups: first and second graders, fourth and fifth graders, and seventh and eighth graders. Among the results, sex differences both in point consistency and in the accuracy of pointings from imagined reference…

A modified viewer rotation procedure was used to contrast two possible explanations of spatial egocentrism in spatial perspective tasks. Subjects were 60 children in first, third, and fifth grades. (MP)

A battery of four tasks which measure the interhemispheric transfer of information was utilized to test the hypothesis that there will be an increase in efficiency of interhemispheric transfer with increasing age. (MP)

Understanding of the principle of verticality was tested by having 246 sixth-grade students draw a pendulum on pictures of an abstract shape similar to a steeple. Girls performed more poorly than boys. Verticality was apparently much better understood by subjects than horizontality, also tested to provide a comparison. (Author)

Reports a study of how adults form mental representations of large scale environments. Findings revealed that people use landmarks as initial anchor points and subsequently elaborate path structures. Multivariate techniques proved to be useful analytical tools. (Author/WB)

Data from a study of spatial representation in blind children were subjected to two stepwise regression analyses to determine the relationships between several subject related variables and responses to "map" (cognitive map) and "route" (sequential memory) questions about the position of furniture in a recently explored room.
