Describes the Death Threat Index and its underlying theoretical base and procedure. Suggests if the procedure is varied slightly, a more qualitative picture of a subject's construct of death is possible. The significance of the complexity and individuality of death constructs for death education programs is considered. (Author/JAC)

Adult performance on verbal analogy and classification problems was assessed in terms of outcomes of process execution. Process-outcomes measures accounted for overall performance and were related to ability. Problem forms differed in terms of which measures predicted individual differences. Common process-outcome measures showed highest…

Strategic differences in spatial tasks are explained in terms of different cognitive coordinate systems that subjects adopt such as standard versus arbitrary, task-defined axes. A theoretical account of mental rotation of individuals of low and high spatial ability solving problems from psychometric tests is instantiated as computer simulation…

The retention of the conditioned response was tested in a retroactive interference paradigm. Results suggested that what is learned by children in simple conditioning paradigms is different than what is learned by adults in the same paradigms. (Author/PN)

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.…

Fifty-five recent studies of individual differences (IDs) in elementary cognitive tasks (ECTs) are reviewed. Twenty-five data sets are examined, analyzed, or reanalyzed by factor analysis. The following promising dimensions are identified: basic perceptual processes, reaction and movement times, mental comparison and recognition tasks, retrieval…

This paper discusses research exploring the performance factors involved in studies which test for formal operations. It is suggested that several previous studies dealing with formal operations confound performance and competence in determining the extent of subjects' formal operations schemata. Factors which might account for performance…

The reliability of derived measures from 4 cognitive paradigms was studied using 19 Navy enlisted men (aged between 18 and 24 years). The paradigms were: graphemic and phonemic analysis; semantic memory retrieval; lexical decision making; and letter classification. Results indicate that derived scores may have low reliability. (SLD)
