Twenty-five retarded and 25 nonretarded children, mean age 16 and 9 years respectively, matched for mental age, performed two-bit (four-choice) and three-bit (eight-choice) problem solving tasks to determine whether group performance differences would increase with task complexity and whether performance of the retarded children would be poorer.…

Several studies have shown that the elderly do not perform well on the Piagetian problems of logical thinking; the present set of studies aimed at demonstrating that the elderly maintain the competence to solve such problems. The first study performed by the authors assessed performance of 60 noninstitutionalized middle-class elderly females on…

Various experiments demonstrated that the difficulty level of several performance-type intelligence test tasks is determined directly by stimulus and task variables that vary the information to be processed. The implications of these findings for intelligence and the problems of an experimental approach to the measurement of intelligence are…

High school students (N=126) responded to questionnaire measures of chronic self-esteem (CSD), task-specific self-esteem (TSSE), and locus of control of reinforcements (L of C) varied in level of task difficulty (TD). The overall relationships of TSSE and L of C with TP were each moderated significantly by TD. (Author)

The study focused on the individual attributes predictive of performance and work satisfaction in two contrasting work situations: (1) with a simple task to be perceived as low on job structural attributes (LJSA) and (2) with a more complex task designed to have a higher level of job structural attributes (HJSA). The job structural variables of…

The study integrates various elements of past approaches to job design. It focuses on determining individual characteristics associated with performance and work satisfaction on a simulated maintenance task designed to be seen as low in job structural attributes (LJSA) by one group and the same task designed to be perceived as high in job…

Describes various performance measures used in a study to investigate the relation of performance pace to age and information processing ability. Test results indicated no differences in performance pace but differences in performance quality between young and older individuals, with implications for hiring and training older workers. (MF)

THE PURPOSE OF THIS SYMPOSIUM WAS TO CONSIDER SOME PROBLEMS FREQUENTLY ENCOUNTERED WHEN PREPARING INSTRUCTIONAL OBJECTIVES AND TO DISCUSS SEVERAL MEANS BY WHICH FUTURE EFFORTS AT IMPLEMENTATION MIGHT BE FACILITATED. TOPICS DISCUSSED INCLUDE--(1) "IN DEFENSE OF INSTRUCTIONAL OBJECTIVES," (2) "SOME IMPORTANT WAYS IN WHICH PERFORMANCE…

This manual discusses general training procedures and describes the workshop method for the functional independence scales of the Balthazar Scales of Adaptive Behavior (BSAB). General training procedures include guidelines for self-instruction for the professional or assistant, instructor and special equipment required. The suggested workshop…

The longitudinal interrelations among age, visual and auditory short-term memory, and the concrete operational tasks of class inclusion and combinatorial reasoning were investigated over four testing occasions in a sample of 134 students, initially ranging from 5 to 12 years in age. The Piagetian task battery involved placement of colored…

Twenty-four children aged five and twenty-four children aged six were interviewed individually three times during a calendar year. It was found that not only did the children's language develop over the period, as judged syntactically and lexically, but they also showed an increasingly fluent control over their own style. All the children…

FIVE EXPERIMENTS WERE CONDUCTED IN AN ATTEMPT TO ISOLATE SPECIFIC LEARNING PATTERNS IN CHILDREN OF VARYING DEGREES OF MENTAL RETARDATION AND TO CONTRIBUTE TO THE KNOWLEDGE OF THE PHYLOGENETIC DEVELOPMENT OF INTELLIGENCE. FACTORS STUDIED WERE THOSE KNOWN TO INFLUENCE LEARNING IN NORMAL CHILDREN AND ADULTS--KIND OF REINFORCEMENT (VERBAL OR…
