Performance with Intelligent Agent Technology:
Implications for Implementation in Organizations

Kimberly A. Hoffman, University of South Florida

Michael D. Coovert, University of South Florida

Intelligent agent technology has the potential to revolutionize individual performance.  Consequently, this research focuses on the impact of agent use on performance.  Data from 38 U.S. Air Force Weapons Directors confirm a positive impact.  Further, the specific sequence in which the agent is employed differentially influences performance.  Implications for organizations are discussed.

Challenges in Computerizing Work Sample Measures:
Testing the Equivalence of an In-Basket Exercise

Robert P. Tett, University of Tulsa

Darcy Menard, Wright State University

Hal Guterman, Wright State University

Russell S. Beauregard, Wright State University

In light of point-to-point correspondence theory, computerized and paper-and-pencil versions of an in-basket exercise were assessed for psychometric equivalence.  Results showed trivial mean differences between modes on 27 managerial competencies, acceptable inter-mode correlations, and similar susceptibility to desirability responding.  Related issues concerning computerization of work samples are discussed. 

Service Businesses: Issues Related to Going from Bricks to Bytes

Edie Schmidt, Purdue University

I-O businesses can learn a lot from understanding the challenges and triumphs that other service sectors have seen related to taking their services online.  This paper outlines some key factors to consider when taking a service product from bricks to bytes.

Telework, Gender, and WorkFamily Balance: A Re-Examination of Linkages

Heather N. Odle, Bowling Green State University

Jeffrey M. Stanton, Bowling Green State University

Lisa Cree, Performaworks

We developed new research propositions concerning whether gender moderated predictions of work-family balance of telecommuters.  We used archival data to conduct preliminary tests of these propositions.  Results suggested the need for modifications to existing theory and highlighted methodological challenges for future research. 

Electronic Monitoring, Privacy, and Organizational
Attraction: A Field Experiment

Lilly Lin, Bowling Green State University

Jeffrey M. Stanton, Bowling Green State University

A field experiment examined the impact of organizational privacy policies and technology on applicant attraction.  Data from 600 African American engineers indicated that policies that failed to protect employee privacy made the organization seem less attractive and were viewed as potential sources of discrimination against minorities.   

Internet Versus Mail Work and Family Surveys: Comparing Demographics

Sidney F. Fisher, George Mason University

Douglas G. Brown, HumRRO

Alison S. OBrien, George Mason University

Louis C. Buffardi, George Mason University

Carol J. Erdwins, George Mason University

Previous literature has demonstrated that Internet surveys yield more demographically varied samples than traditional survey methods. The present study investigates differences between Internet and traditional samples of parents of small children. The Internet sample is marginally different on two demographics from a traditional sample from an affluent suburban area.

Taking the Tech Out of Information Technology: A Meta-Analysis

Gregory A. Barnett, Hogan Assessment Systems

William D. Fleming, University of Tulsa

Business and professional literature often equate information technology (IT) performance solely with technical skills.  The current research attempts to expand the understanding of IT performance by focusing on the personal characteristics that are related to performance. Meta-analytic procedures were used to identify the personality characteristics that predict IT job performance.  

Test Familiarization: Effects on Reactions to Written and Video Tests

Rainer Seitz, Portland State University

Donald M. Truxillo, Portland State University

Talya N. Bauer, Portland State University

This study examined the effects of pretest training on reactions to written and video selection tests.  Results indicated that reactions to the video test were generally more fair, although training enhanced certain written test reactions so that differences were eliminated.  Training also enhanced organizational attractiveness ratings for both formats.

Internet as a Job Source and Job Site Preference

Elizabeth Weiss, Georgia Institute of Technology

Francisco Gabriel Barbeite, Georgia Institute of Technology

Preference for the Internet as a job source and type of job site preferred were examined.  The Internet was highly preferred.  Preferred job sites had few features and required little personal information.  Older workers and women felt less comfortable disclosing personal information at job sites, posing potential legal issues. 

How do Learning Differences Arise Across Media?

Aaron G. Sorensen, DePaul University

Kenneth G. Brown, University of Iowa                                                                                                                       

Megan Werner, University of Iowa

Joan Huntley, University of Iowa

This study compared learning from a digital, computer-based lecture to learning from two other analog forms of media deliveryaudiocassette and videocassette.  Learner choices regarding review effort and time on task did not explain the learning advantage of computer-based over audiocassette lecture.  Future research on media effects is suggested.

E-mail Versus Face-to-Face: Performance Feedback Medium Effects

Derek A. Steinbrenner, Cambria Consulting

Despite the growth of communication media choices, little is known of their effect on workplace communication.  This study examined the effects face-to-face versus e-mail media on recipients perceptions of a performance feedback messages clarity, accuracy, value, and satisfaction.  Results revealed no significant differences between the two groups.

Applicant Preferences for Web-Based Versus Traditional Job Postings

Rebecca R. Zusman, Tulane University

Ronald S. Landis, Tulane University

This study tested hypotheses that (a) applicants would prefer Web-based job postings to traditional paper-and-ink materials, and (b) applicants would prefer jobs on high quality Web pages to those on lower quality pages. The second hypothesis was supported; however, paper-and-ink postings were preferred to those in a Web-based format.

Exploring Temporal Dimensions of Virtual Teams

Darleen Pawlowicz, Temple University

Richard L. Frei, Temple University

Technological advancements in communication media, coupled with an increased reliance on teams, make research on time even more imperative.  This article explores some of the temporal aspects related to virtual teams and asynchronous communication, and proposes a new model from which further theoretical and experimental analyses can be constructed.

21st Century Recruiting: A Model for Internet-Based Realistic Job Previews

Angela Travagline, Temple University

Richard L. Frei, Temple University

Organizational entry is a dual matching process between organizations and applicants.  We propose a model that explores what factors influence the degree of match perceived by individuals/organizations. The model focuses on Internet-based realistic job previews and technology-related issues that changed the way individuals move from outside to inside an organization. 

Video-Based and Written Situational Judgment Tests:
Method Effects and Construct Validity  

Carl Swander, Virginia Tech

This study compared of two alternate formats (video and written) of the same situational judgment.  Cognitive ability and conscientiousness were not related to either test.  Reading ability was not related to the written format.  Emotional accuracy was related to both versions.  More unsupported attributions were made with the video format.  

Equivalence of Traditional and Internet-Based Data Collection:
Three Multigroup Analyses

Steven R. Burnkrant, U.S. Office of Personnel Management

C. David Taylor, University of TexasHouston

In three studies, data from 1,736 participants who completed traditional paper-and-pencil questionnaires were compared to data from 697 participants who completed identical measures over the Internet.  In each study, the groups were highly similar in terms of frequency of missing values, scale reliabilities, and latent covariance structures.

Questions About Adverse Impact Answered by Investigations
Utilizing Computer Simulation

Jerel Slaughter, Louisiana State University

Michael Zickar, Bowling Green State University

This paper reviews and integrates investigations that utilize computer simulation methodology to study adverse impact.  Although it seems that tradeoffs between social (reducing adverse impact) and economic (selection utility) goals are almost always necessary, research examining alternative goals and alternative outcome variables may yield somewhat different conclusions.

Comparing Item Equivalence Across Adaptive and Conventional Administration

David Mohr, Bowling Green State University

Michael Zickar, Bowling Green State University

The purpose of this study was to test for measurement equivalence of items administered in an adaptive test with a nonadaptive test and differences in incumbents and applicants in an exam for computer programmers.  Both methods of administration are equivalent and only minor differences were found between applicants and incumbents.

Measurement Equivalence Between Paper and Web Survey
Methods in a Multinational Company

Scott D. Spera, NCR

Neta Moye, University of Maryland

Prior research has suggested that computerized and paper versions of employee surveys can show measurement equivalence, but this has not been tested outside the U.S. in a multinational company.   Using covariance structure modeling, this study tested for measurement equivalence between paper and Web-based methods across five countries.  Results show that measurement equivalence between methods holds across countries, with some exceptions.   

Computer Adaptive Test Characteristics and Test Takers Reactions

Scott Tonidandel, Rice University

Miguel A. Quiones, Rice University

Ann A. Adams, Rice University

Participants took a computer adaptive test in which the difficulty of the initial item and the difficulty of subsequent items was manipulated. The results indicate that these two features of an adaptive test influence test takers perceptions of performance, which subsequently affects test-taking motivation and satisfaction with the test.
