The Effect Of Combat On Aircrew Subjective Readiness And Lso Grades During Operation Desert Shield/Storm, Scott A. Shappell, David F. Neri May 1992

The Effect Of Combat On Aircrew Subjective Readiness And Lso Grades During Operation Desert Shield/Storm, Scott A. Shappell, David F. Neri

Publications

The effect of operational tasking on aircrew readiness during combat operations continues to be an area of intense investigation within the U.S. Navy. The recent Persian Gulf War provided a unique opportunity to collect data examining aircrew work/rest cycles and operational tasking in a combat environment. For 4 consecutive weeks during Operations Desert Shield and Desert Storm, 18 A-6 and 18 F-14 aviators onboard the USS AMERICA (CV-66) completed daily work/rest logs of their activities while conducting operations from the Red Sea. Activities on the work/rest logs were coded to a resolution of one-half hour. Several flight parameters were also …

Factor Analysis Of The Personal Profile System, Thomas G. Henkel, James Noel Wilmoth Jan 1992

Factor Analysis Of The Personal Profile System, Thomas G. Henkel, James Noel Wilmoth

Publications

Principal components extraction with orthogonal and oblique rotations tested construct validity for the Personal Profile System. MOST-LIKE endorsements of 96 behavioral descriptors were coded with 4, LEAST-LIKE with 1, and unendorsed with 2.5. Descriptor data from 1,045 senior noncommissioned Air Force officers were normalized. Four factors accounted for 85% of total variance, with 19 descriptors loading significantly on two factors and the remaining 77 on just one factor. The measure of sampling adequacy for every descriptor exceeded .94. One factor for the varimax-rotated (best) analysis was bi-scalar, loading on Steadiness and Compliance descriptors; a second resembled Influencing, a third loaded …

Use Of A Commercially Available Flight Simulator During Aircrew Performance Testing, S. A. Shappell, B. J. Bartosh Nov 1991

Use Of A Commercially Available Flight Simulator During Aircrew Performance Testing, S. A. Shappell, B. J. Bartosh

Publications

Investigations of aircrew sustained operations (SUSOPS) have been criticized for employing tasks with no apparent external validity. Because measures obtained directly from aviators flying high-performance aircraft are difficult to obtain, a laboratory compromise is needed. High-fidelity flight simulators used for aircrew training offer the most realistic simulation, but their availability is limited. Personal computer-based flight simulators may provide adequate simulation in, the laboratory at a reasonable cost. This report describes a representative research protocol using a commercially available flight simulator during a simulated aircrew SUSOP.

Factoring The Personal Profile System For Construct Validity: Three Analyses Under Different Standardization Assumptions, Thomas G. Henkel, James Noel Wilmoth Jan 1991

Factoring The Personal Profile System For Construct Validity: Three Analyses Under Different Standardization Assumptions, Thomas G. Henkel, James Noel Wilmoth

Publications

Three types of data were factor analyzed using principal components extractions with orthogonal and oblique rotations to test publisher claims for construct validity of the Personal Profile System (PPS). Behavioral descriptor data from 1,045 senior non-commissioned Air Force officers were factored as raw data, mean corrected data, and standardized z-scores (correlations). The most efficacious solution was produced with standardized z-scores generating four factors accounting for 86% of the total variance. The measure of sampling adequacy for every descriptor exceeded 0.922. The first factor was general with approximately equal loadings on each of the dominance, influencing, steadiness, and compliance dimensions. The …

Star: A Computerized Tutorial In General Psychology, Barbara S. Chaparro, Charles G. Halcomb Jan 1989

Star: A Computerized Tutorial In General Psychology, Barbara S. Chaparro, Charles G. Halcomb

Publications

This study investigated the use of a computerized tutorial--Self-Test and Review (STAR)--in a computer-managed general psychology course. STAR consists of four major modules which provide the student with a variety of learning exercises, including practice quizzes, practice final exams, performance reviews, and structured study questions. The purpose of the study was to determine whether students would choose STAR as a study tool, the effect of lecture versus self-paced settings on the use of STAR, whether students who used STAR would perform better than those who did not, and the effect of the timing of feedback in STAR on performance. Students …

Theoretical Considerations For Extracting Meaning From Personal Profile System Data: The Need For Independent Construct Validity Studies, Thomas G. Henkel, James Noel Wilmoth Jan 1988

Theoretical Considerations For Extracting Meaning From Personal Profile System Data: The Need For Independent Construct Validity Studies, Thomas G. Henkel, James Noel Wilmoth

Publications

The Personal Profile System (PPS) is a psychological testing instrument that has been widely used. The construct validity of the PPS was studied through a review of the literature. This paper organizes the literature review into three broad categories: the background of the PPS; the reliability of the PPS; and the validity of the PPS. The PPS is a self-scoring instrument measuring the behavioral responses of people along four dimensions: (1) dominance; (2) influencing; (3) steadiness; and (4) compliance. The instrument is designed to provide a systematic and comprehensive perception of an individual's behavioral tendencies and the behavioral tendencies of …

The Development Of Speech Research Tools On Mit's Lisp Machine-Based Workstations, D. Scott Cyphers, Robert H. Kassel, David H. Kaufman, Hong C. Leung, Mark A. Randolph, Stephanie Seneff, John E. Unverferth Iii, Timothy Wilson, Victor W. Zue Jan 1986

The Development Of Speech Research Tools On Mit's Lisp Machine-Based Workstations, D. Scott Cyphers, Robert H. Kassel, David H. Kaufman, Hong C. Leung, Mark A. Randolph, Stephanie Seneff, John E. Unverferth Iii, Timothy Wilson, Victor W. Zue

Publications

In recent years, a number of useful speech- and language-related research tools have been under development at MIT. These tools are aids for efficiently analyzing the acoustic characteristics of speech and the phonological properties of a language. They are playing a valuable role in our own research, as well as in research conducted elsewhere. This paper describes several of the systems being developed for use on our Lisp Machine workstations.
