Analyzing The Effects Of Display Characteristics And Cognitive Variables On Performance Using Keystroke And Eye Movement Data, Orhan E. Beckman

Psychology Theses & Dissertations

Information about how operators use their eyes while interacting with visual displays is often an overlooked aspect of human-computer interaction. Such information is fundamental to assessing the quality of software interfaces and understanding the cognitive processes that underlie operator behavior. Other research evaluating information displays evolved from using reaction time and subjective data as dependent variables to using oculometric measures. In the current research conventional performance measures are coupled with oculometric measures to evaluate the influence display characteristics and cognitive variables have on performance.

Twelve subjects used a software program to complete a series of specified tasks. Subjects were asked …

A Psychophysiological Assessment Of The Efficacy Of Event-Related Potentials And Electroencephalogram For Adaptive Task Allocation, Lawrence J. Prinzel Iii

Psychology Theses & Dissertations

The present study was designed to test the efficacy of using Electroencephalogram (EEG) and Event-Related Potentials (ERPs) for making task allocations decisions. Thirty-six participants were randomly assigned to an experimental, yoked, or control group condition. Under the experimental condition, a compensatory tracking task was switched between manual and automatic task modes based upon the participant's EEG. ERPs were also gathered to an auditory, oddball task. Participants in the yoked condition performed the same tasks under the exact sequence of task allocations that participants in the experimental group experienced. The control condition consisted of a random sequence of task allocations that …

The Influence Of Model Features On Goodness-Of-Fit Indices: Choosing Indices To Evaluate Your Model, Andrea E. Berndt

Psychology Theses & Dissertations

Two studies were conducted to examine the performance of eight goodness-of-fit indices (i.e., the chi-square statistic, Comparative fit index, Critical N; Goodness-of-fit index, Normed fit index, Nonnormed fit index, Root mean square error of approximation, and Relative noncentrality index) used in structural equation applications. Study 1 consisted of (a) an empirical review in four journals (1986-1996) to determine the "typical" application, (b) a "recreation" of the goodness-of-fit indices from the published research, (c) a multiple regression analysis of the "recreated" indices to determine if values were predicted based on model and sample features, and (d) the development of a representative …

Effects Of An Interview Guide On The Accuracy Of Ratings For Applicants With Disabilities, Catherine Quinn Greenwald Mergen

Psychology Theses & Dissertations

The problem of bias in the employment interview for applicants with disabilities was addressed with research to identify if a decision aid can increase the decision making accuracy of interviewers. A survey designed to allow participants to rate applicants with five disabilities for three jobs (with three essential functions listed for each job) was used to assess rating accuracy of two groups. Participants who received the decision aid in the form of a Guide to Interviewing People with Selected Disabilities were expected to have more rating accuracy than those participants without access to the Guide. Accuracy was assessed by comparing …
