Industrial/organizational psychology applies psychological science to workplace problems — improving how organizations select, develop, motivate, and manage employees while enhancing employee well-being and performance. PSY6710 establishes the foundational knowledge base every I/O psychologist needs, anchored in the Society for Industrial and Organizational Psychology's (SIOP) Principles for the Validation and Use of Personnel Selection Procedures.
Job analysis
Job analysis is the systematic process of identifying the tasks, duties, responsibilities, and required knowledge, skills, abilities, and other characteristics (KSAOs) of a job — the foundation for virtually every other I/O psychology activity (selection, training, performance appraisal, compensation, job design). Methods include: observation, interviews with job incumbents and supervisors, structured questionnaires (Position Analysis Questionnaire — PAQ; the federal O*NET database), and critical incident technique (Flanagan, 1954 — collecting specific examples of effective and ineffective job behavior). Job analysis outputs include job descriptions (task-oriented) and job specifications (worker-oriented, listing KSAOs). Competency modeling has emerged as a complementary, more strategically-oriented approach that links individual capabilities to organizational strategy.
Personnel selection and validity
Validity evidence in personnel selection
- Criterion-related validity: The correlation between a predictor (test score) and a criterion (job performance) — concurrent validity (predictor and criterion measured at the same time, using current employees) and predictive validity (predictor measured before hire, criterion measured later, using actual applicants) — predictive designs are methodologically stronger but harder to implement
- Content validity: The degree to which test content represents the actual job content domain — established through expert judgment linking test items to job analysis results
- Construct validity: The degree to which a test measures the theoretical construct it claims to measure — established through convergent evidence (correlating with other measures of the same construct) and discriminant evidence (not correlating with unrelated constructs)
- Meta-analytic validity generalization: Schmidt and Hunter's research program demonstrating that validity coefficients for cognitive ability tests generalize across jobs and settings, challenging the earlier "situational specificity" hypothesis; general cognitive ability remains the single best predictor of job performance across virtually all jobs, with structured interviews, work samples, and conscientiousness adding incremental validity
- Adverse impact and the four-fifths rule: A selection procedure has adverse impact if the selection rate for a protected group is less than 80% of the rate for the group with the highest selection rate; adverse impact triggers legal scrutiny under Title VII (Griggs v. Duke Power, 1971; Uniform Guidelines on Employee Selection Procedures, 1978), requiring employers to demonstrate job-relatedness and business necessity
Performance appraisal
Performance appraisal systems formally assess employee job performance, serving both administrative purposes (compensation, promotion, termination decisions) and developmental purposes (feedback, goal-setting, skill development). Common rating formats include graphic rating scales, behaviorally anchored rating scales (BARS — anchored with specific behavioral examples to reduce rater subjectivity), and 360-degree feedback (gathering ratings from supervisors, peers, subordinates, and self). Rating errors that I/O psychologists must understand and mitigate include halo effect (allowing a general impression to influence ratings on specific dimensions), leniency/severity bias, central tendency bias, and recency effects (overweighting recent performance).
Work motivation theories
- Expectancy theory (Vroom, 1964): Motivation = Expectancy (effort → performance belief) × Instrumentality (performance → outcome belief) × Valence (value of the outcome)
- Goal-setting theory (Locke & Latham): Specific, difficult goals (within reason) produce higher performance than vague or easy goals, when accompanied by feedback and goal commitment — one of the most empirically robust theories in I/O psychology
- Equity theory (Adams, 1963): Employees compare their input-to-outcome ratio to relevant comparison others; perceived inequity (under-reward or over-reward) motivates behavior to restore balance
- Job characteristics model (Hackman & Oldham, 1976): Five core job dimensions (skill variety, task identity, task significance, autonomy, feedback) influence critical psychological states (meaningfulness, responsibility, knowledge of results) that drive motivation, satisfaction, and performance
- Self-determination theory: Applied to workplace motivation — autonomy-supportive management practices foster intrinsic motivation and well-being more effectively than purely extrinsic, controlling approaches

Frequently asked questions
This is one of the most empirically established and frequently discussed findings in I/O psychology, anchored in Schmidt and Hunter's decades of meta-analytic research (most comprehensively summarized in Schmidt & Hunter, 1998, "The Validity and Utility of Selection Methods in Personnel Psychology," Psychological Bulletin). Their meta-analyses, aggregating validity coefficients across thousands of studies and millions of employees, found that general cognitive ability (GCA, often called "g") has an average uncorrected validity of approximately .51 for predicting job performance across virtually all jobs studied — higher than any single predictor and remarkably consistent across job complexity levels (though the validity is somewhat higher for more complex jobs). This challenged earlier assumptions (the "situational specificity hypothesis") that validity coefficients were highly job-specific and couldn't be generalized — a finding with major practical implications because it meant organizations didn't need to conduct a costly local validation study for every job; well-established meta-analytic validity evidence could be generalized (the foundation of "validity generalization" arguments in legal defense of selection systems). Importantly, GCA's validity is substantially improved when combined with other predictors that add incremental validity beyond cognitive ability alone — particularly structured interviews, work sample tests, conscientiousness (a Big Five personality trait), and integrity tests. A selection system combining GCA testing with a structured interview, for example, achieves substantially higher validity (around .63) than either alone. This combination principle, along with the adverse impact concerns associated with cognitive ability testing (which tends to show larger group differences than some alternative predictors), is a key practical and ethical consideration covered in PSY6710's discussion of selection system design.
