To Lead A Team: Construct Validity Evidence For Team Leadership In The High-Tech Industry, Johanna M. Merritt

Psychology Theses & Dissertations

Two studies were conducted to gather evidence of construct validity for functions of team leadership. The research built on a continuing line of background research. Three hundred and thirty-seven team leaders from sixty-three companies in the manufacturing electronics industry participated in the studies and completed surveys.

Four types of validity evidence were examined: content, criterion-related, convergent, and discriminant. Content validity evidence was demonstrated in Study 1. The overwhelming majority of team leaders perFormed the proposed functions and rated them as important. A confirmatory analysis did not indicate a parsimonious fit among the seven functions that were generated from background research …

Fostering The Development Of Domain-General, Nonlinear Mental Models: A Foundation For Systemic Thinking, Jeffrey S. Sinn

Psychology Theses & Dissertations

Two experiments examined whether people can develop a domain-general, nonlinear mental model when provided with an appropriate conceptual model. Both experiments presented causal loop models (i.e., variables connected in a circle by arrows representing causal relationships) as a conceptual model for positive feedback. Study 1 found that participants trained in causal loop modeling could accurately represent scenarios of low but not high complexity. Study 2 expanded on the design of Study 1 by varying the type of training and type of aid presented during testing. Participants received training with modeling instruction, training with cue-utilization instruction (i.e., participants were trained to …

Structural Equation Modeling Of Attitudes Toward Employment Testing, Laura Susan Hamil

Psychology Theses & Dissertations

This research investigated the relationships among past testing experiences, testing attitudes, perceptions of test performance, race, and gender. In addition, the effects of testing information on testing attitudes were studied. Two hundred and twelve applicants to a variety of positions in a large telecommunications company were asked to complete a series of questionnaires before and after employment testing. The questionnaires included measures of testing experience, general and specific testing attitudes, and perceptions of test performance. Scores on the employment test were also obtained as a measure of cognitive ability. Of the 212 participants, half were given a brochure to read …

Towards Understanding Why Assessment Centers Work: An Evaluation Of The Subtle Criterion Contamination Hypothesis, Christopher T. Rotolo

Psychology Theses & Dissertations

The success of the assessment center method in predicting job performance has been one of the most researched efforts in personnel psychology (Thornton, 1992). However, there is little reported evidence showing that assessment center procedures produce scores that serve as valid representations of separate constructs (Klimoski & Brickner, 1987). It is perhaps ironic, then, that despite the success stories, we still do not understand why assessment centers "work," (i.e., predict performance).

This study examined the subtle criterion contamination hypothesis as an explanation to assessment center validity. The subtle criterion contamination hypothesis states that assessment centers predict managerial performance because assessors …

A Survey Of Health Care Personnel's Perceptions Toward Diversity In The Workplace, Jacqueline Elaine Sharpe

Health Services Research Dissertations

The purpose of this study was to explore the diversity climate in a large teaching military hospital by assessing the perceptions of employees regarding the organizational climate, including aspects of the climate related to ethnicity, gender, age, physical ability, sexual orientation, and job level. All 3,176 eligible employees based in the medical center were invited to participate, 1,252 did so (RR = 40%). Participants were 37% minority, 57% females, 25% officer, 30% enlisted, and 45% civilian. Twenty-four percent were at the managerial level. Perceptions of the diversity climate were measured using the Diversity Survey Instrument (the reliability and validity of …

The Effects Of Human-Computer Communication Mode, Task Complexity, And Desire For Control On Performance And Discourse Organization In An Adaptive Task, Cristina Bubb-Lewis

Psychology Theses & Dissertations

The present study examined how different communication patterns affected task performance with an adaptive interface. A Wizard-of-Oz simulation (Gould, Conti, & Hovanyecz, 1983) was used to create the impression of a talking and listening computer that acted as a teammate to help participants interact with a computer application.

Four levels of communication mode were used which differed in the level of restriction placed on human-computer communication. In addition, participants completed two sets of tasks (simple and complex). Further, a personality trait, Desire for Control (DC), was measured and participants were split into high and low groups for analysis. Dependent measures …
