The conditions under which stimulus over-selectivity occurred were studied using a matching-to-sample procedure with non-autistic adults. A matching-to-sample discrimination learning task with a number of sample-comparison retention intervals was used. The results demonstrated that an increase in retention interval increased the degree of stimulus…

We study human decision making in a simple forced-choice task that manipulates the frequency and accuracy of available information. Empirically, we find that people make decisions consistent with the advice provided, but that their subjective confidence in their decisions shows 2 interesting properties. First, people's confidence does not depend…

Group discussions tend to focus on information that was previously known by all members (shared information) rather than information known by only 1 member (unshared information). If the shared information implies a suboptimal alternative, this sampling bias is associated with inaccurate group decisions. The present study examines the impact of 2…

A method of water learning (teaching low level motor coordination in water, rather than on land) has been developed for stimulating the growth and skills of severely handicapped students. The model, which attempts to elicit natural developmental responses to the environment, incorporates task analysis of developmental preswimming sequences…

Presents formulas, ideas, and comments about staffing requirements in the custodial program. (Author/MLF)

How Personalized System of Instruction (PSI) is used with task analysis for Navy training. (HB)

To test people's ability to underestimate time requirements during planning, researchers conducted three experiments in which subjects had to estimate the time needed to do hypothetical errands in an imaginary town. The subjects comprised three separate groups of students and citizens. Variables tested included the number of errands, the total…

This report describes a quantitative study of subject-indexing as it is being performed by catalogers who are developing an augmented catalog as part of Project Intrex. Learning curves for the average time taken to index technical documents on a per-page basis were derived for a group of indexers. The average indexing times per page were also…

The directory of task inventories (listings of activities performed by workers on their jobs) contains bibliographic entries for 171 documents published by State educational and employment service agencies, occupational curriculum laboratories and research coordinating units, branches of the Armed Forces, selected private research and development…

The information reported in this directory was compiled from a review of documents from state educational and employment service agencies, occupational curriculum laboratories and research coordinating units, branches of the armed forces, selected private research and development agencies, and other organizations. Task inventories resulting from…

This document reports on the activities of educational consultants involved in the appraisal of the Evaluator Development Program. Included are (1) consultant suggestions for program improvement, (2) a tabulation of consultant responses to task items on the consultant form, (3) a list of consultants, and (4) materials used during the evaluation…

In this study, the social structure and output of scholars at the University of Illinois are examined in terms of the task characteristics of their academic areas. On the basis of an earlier multidimensional analysis, academic task areas were clustered according to their: (1) concern with objectivity and physical objects; (2) concern with…

A computer simulation model was fitted to human laboratory data for the Missionaries and Cannibals task to explain the effects upon problem performance of giving a hint and the effect of solving problems a second time after a successful solution has been achieved. (Author/DEP)

Presents a task checklist designed to assist in implementation of the Responsive Education Program, or any new instructional program. (RAO)
