Principles Of Design For Complex Displays: A Comparative Evaluation, Sharolyn Ann Converse
Principles Of Design For Complex Displays: A Comparative Evaluation, Sharolyn Ann Converse
Psychology Theses & Dissertations
The present study examined the main and interactive effects of information format, information density, principle of information grouping, orientation of the airspeed scale, and task type on response time (RT) and accuracy in a decision making task. Forty-eight college students viewed static displays of primary flight instruments and signaled responses to the displays by pressing keys on the computer keyboard. Three levels of task type were employed. In the current state estimation task, subjects were required to determine whether each individual instrument reading was within prespecified limits. In the future state estimation task, subjects were required to attend to the …
Performance Appraisal Ratings As A Function Of Source Of Ratings And Purpose Of The Appraisal, Richard J. Tannenbaum
Performance Appraisal Ratings As A Function Of Source Of Ratings And Purpose Of The Appraisal, Richard J. Tannenbaum
Psychology Theses & Dissertations
This study investigated the effects of purpose of appraisal ratings and source of appraisal ratings on four dependent measures: leniency, halo, variability, and construct validity. The purpose factor was comprised of four different levels: merit pay, performance improvement, research only, and no defined appraisal purpose. The rating source factor was comprised of two different levels: incumbent self-ratings, and supervisor ratings. One hundred and nineteen nursing assistants provided the self-ratings, and 39 nurses provided the supervisor ratings. Both sets of ratings were made using a 13-dimension graphic-type rating scale. Analysis of variance procedures were used to test the effects of appraisal …
Investigation Of Display Issues Relevant To The Presentation Of Aircraft Fault Information, Donald Mark Allen
Investigation Of Display Issues Relevant To The Presentation Of Aircraft Fault Information, Donald Mark Allen
Psychology Theses & Dissertations
The present study investigated the effects of different display, hypothesis presentation, information presentation, and parameter presentation styles on pilot performance. It was hypothesized that performance would be maximal using picture-based displays, presenting hypothesis information as a composite, showing only out-of-tolerance parameter information, and when parameter information was displayed as a bargraph. The results of the study indicated that pilot performance was best when employing picture- and text-based displays, when fault hypotheses were displayed as composites. There were no differences in response times when picture- and text-based displays were compared. Subjects' performances were best when hypotheses were displayed as composites compared …
Natural Language Human-Computer Dialogue: Menu-Based Natural Language And Visual Performance, Jeffrey John Hendrickson
Natural Language Human-Computer Dialogue: Menu-Based Natural Language And Visual Performance, Jeffrey John Hendrickson
Psychology Theses & Dissertations
The present study was conducted to determine design principles for menu-based natural language (MBNL) interfaces and to provide evidence for the nature of visual search processes with menu-based systems. The effects of window size, window activity, and query length were investigated. Window size was manipulated as a between-subjects variable with three levels representing a sixteen-item window size, an eight-item window size, and a four-item window size. Window activity was manipulated as a within-subjects variable with two levels representing single active and multiple active windows. Query length was manipulated as a within-subjects variable with three levels representing one-, two-, and three-item …
Dynamic Allocation Of Responsibility Between Operators With Different Models Of System Information Using Computer-Mediated Communication, Michele Terranova
Dynamic Allocation Of Responsibility Between Operators With Different Models Of System Information Using Computer-Mediated Communication, Michele Terranova
Psychology Theses & Dissertations
This research focused on the effectiveness of two operator teams for dynamic control of a process simulation. The responsibility for system optimization and failure detection was shared by the operators through computer-mediated communication. System information was displayed to both operators by one of three mental models of the systems: an alphanumeric/separable representation, a graphic/integral system representation, or both representations. The following team-display configurations were used: primary operator with graphic display, support operator with alphanumeric (GRAL); primary operator with alphanumeric display, support operator with graphic (ALGR); both operators with alphanumeric displays (BOAL); both operators with graphic displays (BOGR); and both operators …
