In the present study the relationships between the amount of freedom given the learner in choosing a learning task and his subsequent performance and persistence on that task were investigated. (Author)

The present paper describes an attempt to establish a paper and pencil test battery for improving predictive efficiency in the selection of supporting services personnel at Montgomery County Public Schools and a report on the validation of such a procedure. (Author)

Builds upon earlier experiments in an attempt to measure the interferences between simultaneous tasks and the effects of hypnotic dissociation in increasing or decreasing this interference, thus testing the validity of one or the other of two theoretical models. (Author/RK)

Study was designed to provide further evidence on the speed of development of the acquired distinctiveness and equivalence effects during the transfer task. (Author)

A mail survey of vocational-techncial teachers in Texas was conducted to identify tasks performed, knowledge required, and amount of time spent in the performance of these tasks. A questionnaire was given to 1,149 vocational-technical teachers with 85 percent responding. The teachers were classified according to vocational program areas and were…

The study was conducted to develop methods for using timely, firsthand occupational task information on automotive mechanics in order to identify critical performance requirements that warrant formal training. The methodology used is described in detail. A Task Inventory Questionnaire was completed by 18 auto mechanics and 12 supervisors in each…

Results indicate that identity conservation generally does not precede equivalence conservation; instead the two conservations tend to co-occur. (Authors)

Data confirmed Kukla's attributional theory of performance. When a task is perceived to be difficult, high resultant achievers perform better than low resultant achievers, whereas the low motive group proves to be superior to the high group when the task is perceived as easy. (Author/RK)

Results strongly support a self-terminating, feature-testing, contingent mode of information processing. (Author)

It was shown that hierarchies change with development and that relative salience of a dimension is negatively associated with both reaction time of choice and number of errors on the identity task. (Authors)

Heart rate indexes of reaction time (RT) were investigated in male college students. (Author)

The range of assessments made by teachers of the performance of their students in the Nuffield Advanced Biology project and the Nuffield Advanced Physical Science project was subjected to a factor analysis. (Author)

A lab study was conducted to test the effect of different kinds of instruction in copying tasks, which are considered to be a fundamental function in the area of psycho-motor skills. The study was organized as a two-way design with 24 eight-year-old Ss. (Editor)
