Studies of human problem solving have traditionally used deterministic tasks that require the execution of a systematic series of steps to reach a rational and optimal solution. Most real-world problems, however, are characterized by uncertainty, the need to consider an enormous number of variables and possible courses of action at each stage in…

Confirms that perceptual and linguistic differences exist between middle-class and lower-class children, favoring middle-class children, and lends support to the usefulness of the Vane Kindergarten Test as a screening test for determining the intellectual potential of young children. (RB)

It identifies cognitive, affective and educational variables which have been either shown or hypothesized to contribute to sex-related differences in mathematics learning. The author analyzes each study in detail. One important finding…

The effect of reading practice upon reading ability was investigated in three separate studies, with six high school students in each study. Each student was given 50 to 70 hours of individualized instruction on a PLATO IV computer terminal. Half of the students in each study were selected on the basis of high scores on the Raven Progressive…

This student booklet is third in an illustrated series of eleven learning activity packets for use in teaching job hunting and application procedures and the management of wages to secondary students. Three units are included in this packet: unit 1 discusses the purpose of the interview, questions frequently asked, and items that the applicant…

Using a sample of 77 10th grade boys, the researchers studied the relationships between the mental abilities measured by the Differential Aptitude Tests and cerebral dominance (CD: the extent to which one hemisphere of the brain dominates the other for control of behavior). The surprise finding was that CD was negatively related to spatial…

Several propositions about the relationships between and among environmental variables of relevance to IQ were tested. Environmental variables hypothesized to be related to IQ were measured longitudinally across three time periods in childhood (0-3, 4-6, 7-10 years) on a sample of 110 subjects. (Author/CS)
