Professor

Psychology

Dr. Guastello's research interests fall into several areas. The largest concerns nonlinear dynamics (chaos, complexity, and catastrophe theories, and related principles) and their applications to work motivation, work performance and turnover, occupational safety and health, creativity, group and organizational behavior, and cognitive workload and fatigue. Dr. Guastello's other interests include the role of macroeconomics in organizational behavior, human-computer interface design, computer-based test interpretations and expert systems, personality and organizational behavior.

Education

Ph.D., Illinois Institute of Technology, 1982
M.A., Washington University, 1979
B.A., Johns Hopkins University, 1977

Courses Taught

SJG's teaching responsibilities include industrial psychology and organizational development at the undergraduate (PSYC 3230) and the graduate levels (PSYC 8665) .  Human Factors (PSYC 4330), which is the study of person-machine interaction, is also available as a graduate course (PSYC 5330). SJG also teaches Theories of Personality (PSYC 3501). He has also taught General Psychology regularly, plus a few other courses on an occasional basis, such as Graduate Statistics 2 and a special topics seminar, Chaos and Complexity in Psychology (PSYC 4995).

Software

Peressini, A. F., & Guastello, S. J. (2016-2022). Synccalc 2.1. Synccalc is an algorithm for determining the degree of physiological synchronization (e.g. in electrodermal responses) that exists within a group or team while performing a task. It begins with a matrix showing the influence of each person on every other person in the group. The group member with the greatest influence is the “driver.” The group member who is most responsive to the others in the group is the “empath.” The synchronization coefficient represents the total level of group influence relative to the empath’s perspective. Available from: https://academic.mu.edu/peressini/synccalc/synccalc.htm

Peressini, A. F., & Guastello, S. J. (2014). Orbital Decomposition v2.4. ORBDE is an analysis based on symbolic dynamics that identifies recurring patterns of events in nominally-coded data. In other words, the events can be identified by categories, rather than metrics. The final statistics include the string length, topological entropy in the form of the (largest) Lyapunov exponent, fractal dimension, Shannon entropy, and a chi-square test for goodness of fit. V2.4 contains aggregation functions that accommodate multiple categorical variables.

 

Professional Interests

Editor in Chief: Nonlinear Dynamics, Psychology, and Life Sciences.  This is the refereed research journal of the Society for Chaos Theory in Psychology & Life Sciences. SJG is the founding Editor in Chief, and currently continues in that capacity. NDPLS was first published by Human Sciences Press, Div. Plenum in 1997-98 and by Kluwer Academic Publishers, now part of Springer Inc., during the years 1999-2003. NDPLS is now published directly by the Society. SJG also manages its production operations. For journal purview, instructions for authors, subscription information, citation rates and indexes, please visit the NDPLS site above.

Theoretical Issues in Ergonomics Science. SJG was appointed to the editorial board in 2002. Published by Taylor and Francis.

Consultant to Industry
The most frequently requested projects have involved the application of basic research in nonlinear dynamics for personnel selection and retention, occupational accident analysis and prevention, and management development. Portions of the work have involved writing, administration, and analysis of surveys for occupational safety, organizational development efforts, and knowledge acquisition for expert systems. Other projects include the development of personnel selection systems and selection test validation for executives, salespeople, controllers, operations, skilled trades, and support personnel.
