The ability to recognize temporal patterns and position events in time emerges during the preschool years and is refined in middle childhood. This study explored individual differences in temporal cognition in relation to verbal and nonverbal abilities. Children (30 boys, 32 girls; M[subscript age] = 8;2, age range = 6;0-10;8) completed 3…

In this research we explored the relationship between spatial activities in the home and spatial ability at the start of formal schooling at age four. In total, 30 children participated in this research. Data sources included a demographic questionnaire, a survey of at home spatial activities, and standardized testing in verbal and non-verbal…

Recent efforts have been made to develop more age-appropriate intelligence measures for the elderly to determine the nature of age differences and changes in adult cognitive development. Spatial and reasoning performances of young, young-old and old-old individuals were compared on traditional versus familiar and presumably more meaningful…

The inter-subject/intra-subject subtest patterns (profiles) of the same sample of gifted children were examined based on factors found in a previous study of the Raven Coloured Progressive Matrices Test (CPM) that investigated structural properties with specific application to a sample of gifted children. The sample consisted of 166 children (78…

As part of a continuing evaluation of the Swedish school system, changes in intelligence test scores from 1960 to 1995 were studied in relation to cohort, gender, and socioeconomic background. Changes in verbal, spatial, and reasoning ability were studied by comparing results on identical tests given to representative samples of Swedish…

Tests of spatial ability were analyzed for their analog (visuospatial) and nonanalog (verbal reasoning) components, using factor analyses of items and test scores. The self-selected sample consisted of over 2000 clients (average age about 26 or 27) employing the Johnson O'Connor Research Foundation's aptitude evaluation services in 12 metropolitan…

Recent theorists have begun to re-conceptualize the construct of "intelligence." This paper reviews recent theories of intelligence and indicates implications for practitioners, educators, and individuals. Theories and theorists discussed include the following: (1) Robert Sternberg has advanced the "triarchic theory" of…
