What We Learned from a Computational Model of Job Attitudes and Stress Justin M. Weinhardt & Jeffrey B. Vancouvera Ohio University a This work is supported by NSF (grant #0851764), with funding from the American Recovery and Reinvestment Act of 2009.
The Humble Scientist • Dynamics are difficult • Humans are ill-equipped • Support mechanisms have been created • mathematics • statistical analysis • computational modeling
The Computational Approach • Increases precision and transparency • Assures internal (logical) consistency • Identifies unanticipated consequences • Motivated a workshop: • Used attitudes/stress models as example
The Ubiquitous Comparator • Hulin & Judge’s (2003) review of job attitude models
Part of Edward’s Theory of Stress and Well-Being Desires Discrepancy Well-Being Coping Perception Physical and Social Environment
Computational Model: Vensim 0 desires Well-Being/ ∫(-discrepancies)dt discrepancies discrepancies desires - perceptions Job Satisfaction perceptions actions/coping actions/coping Environmental States perceptions behaviors behaviors initial state Environmental ∫("actions/coping behaviors" * environmental responsiveness)dt 0.1 States environmental responsiveness
Problem #1: Acting to make things worse desires 0 Well-Being/ discrepancies Job Satisfaction actions/coping negative actions perceptions behaviors initial states |discrepancies|; or discrepancies2 ; or If d > 0, discrepancies else, -discrepancies/2 1 Environmental States environmental responsiveness 0.1
Problem #2: Runaway positive feedback loop desires 0 Well-Being/ discrepancies Job Satisfaction actions/coping perceptions behaviors initial states 1 Environmental States environmental responsiveness 0.1
Theoretical Implications Here lies affect as mediator theories (e.g., social cognitive theory) Here lies symmetric comparator control theories actions/coping If d > 0, discrepancies + 1 else, ediscrepancies Equity theory (Adams, 1963) behaviors
Add Opponent Process equilibrium level opponent desires process rate Well-Being/ discrepancies Job Satisfaction actions/coping perceptions behaviors Environmental States environmental responsiveness initial state
