Twenty-eight kindergarten children (5-6 years old) were tested in order to identify children with learning disabilities and to compare tests results. (Author)

A number of linguistic problems identified through analysis of primary mathematics texts are discussed. These include vocabulary, readability and perception. (MP)

Three experiments assessed the effect of visual familiarity of words on "same-different" reaction times (RTs) in a simultaneous-matching task. All three studies showed visual familiarity to be responsible for differences in slope over sequence length between words and nonwords. (Editor/RK)

Early acquisition of right and left as absolute concepts does not seem to be related to early mastery of right and left as relative concepts among the Hausa. (Author)

The physical identity reaction time task used in this study was designed to further test the effect of processing mode uncertainty on visual field asymmetries that Swanson et al. (1974) reported, and to determine the effects of location uncertainty in a cognitive task. (Author/KC)

Two experiments were conducted to compare the effectiveness of different ways of producing the frames in a remedial self-instructional program intended to improve the ability of Nigerian secondary school students to understand spatial relationships in pictures. (Author/AM)

Analysis of recent literature covering visual experiments with infants and young children documented a progression of visual functions in early development. (Author)

Presents a study of perspective taking ability among children aged 3 to 7. The first task involved a classic block appearance task. In the second task, the child and/or the experimenter each wore different colored glasses and the child was asked to describe how a white card appeared to each of them. (BD)

A report and discussion is given of some of the results of testing students at the Papua New Guinea University of Technology on diagrams which involved the use of visual conventions. (MN)

Reports on a series of four experiments designed to determine more precisely the characteristics of the stage of visual feature analysis of word identification and to examine response competition factors in this interference task. (SB)

Examines the implications of image analysis and discusses two different strategies, one relating to content and one relating to form. (MH)

The data do not support either the expectations that males are invariably superior in mathematics achievement and spatial visualization or the idea that differences between the sexes increase with age and/or mathematics difficulty. The pattern of differences in mathematics achievement, spatial visualization and affective variables strongly…

The experiments reported here are aimed at exploring in more detail the possibility that context can improve perception itself. In particular, they are concerned with clarifying the conditions under which context might aid perception and with localizing the stage of processing at which context would have its effects. (Author)
