"Recognitional capacity"--the ability to recognize when procedures apply--is needed in order to perform tasks; this capacity cannot be replaced by higher-level procedures. As a result, guidebooks that attempt to provide step-by-step procedural accounts of task performance face an insurmountable barrier. User guides that attempt to show…

This study measured the feature selection and classification ability of 213 children between the ages of four and sixteen through an analysis of their sorting performance from a developmental point of view. (CM)

The manual was designed to help vocational education curriculum experts learn procedures for constructing task inventories and for analyzing occupational performance. The manual opens with definitions of a task inventory and other terms, and an overview of the procedure. The first six steps involve the overall construction of an initial task…

This research uses a complex task (handwheel assembly) to enable comparison between the performance of mentally handicapped adults and adults from a "normal" population, in the acquisition of new work skills. Results add further support for the notion that the potential of mentally handicapped individuals is commonly underestimated. (Editor/RK)

This study was submitted in partial fulfillment of the requirements for the M.S. degree at Purdue University, August 1968.

A case is made that typing, speaking, and playing music are members of a family of skills that can be studied within a common theory. (Editor)

Extensive job sample tests and multiple choice job knowledge tests were administered to approximately 370 men in each of four Army jobs: Armor Crewman, Repairman, Supply Specialist and Cook. Representative tasks in each job were analyzed and skill requirements were identified. This analysis and the correlations between job sample scores and job…

Job complexity was measured for jobs in a public agency. Perceptions of job complexity were obtained from self-reports. Independent measures were obtained from interviews with subjects. Career stages were found to moderate relationships between job satisfaction and perceived job complexity and between job-performance and independently rated job…

Summarizes five task analysis approaches to determining what people need to know and do to perform their jobs successfully. (EM)

Deficiencies in job performance are not always due to a lack of knowledge, but frequently are the result of not knowing proper procedures and methods to get the job done. Recognizing the difference between deficiency in knowledge and deficiency in skills is the key to improving performance without training. (Editor)

Subjects classified according to degree of hand preference were tested with both hands on two tasks of controlled movement. (Editor)

Three experiments were undertaken to examine the processing limitations that underlie multiple task performance and, ultimately, to test the theory that there exists a time-sharing ability which is general and can be assessed through the simultaneous presentation of any two or more sufficiently demanding tasks. Subjects were males and/or females…

The report presents a brief summary of the development and application of a taxonomy of undergraduate pilot training (UPT) tasks and skills. A surface analysis format based on cues, mental actions, and motor actions was developed which described flying tasks in terms of the sequential elements within each task. A set of classification rules was…

Performance tests are used in training evaluation to (1) certify student achievement, and (2) diagnose weaknesses in the instructional system. Proficiency measures that focus on task outcomes (product) normally provide data relevant to the first purpose, whereas measures of how the tasks are carried out (process) pertain to the second. Time or…

The standard for grading jobs under the Federal Wage System covers nonsupervisory work involved in handling, marking, and preparing displays of merchandise or other items for selection by customers. This requires skill in observing, counting, and maintaining stock levels, and in matching names, codes, numbers, or sizes of items on shelves to lists…
