What are the effects of a compressed workweek on job outcomes?
Increases satisfaction with schedule and work–life balance; minimal effect on objective performance or supervisor ratings.
What is the primary purpose of a leaderless group discussion?
To assess or develop leadership and interpersonal competence, often within assessment centers for managerial candidates.
What does differential validity indicate?
The predictor–criterion relationship (slope of regression) differs between subgroups, suggesting the test predicts differently across them.
When is a selection test most useful according to the Taylor–Russell tables?
When the base rate of success is moderate (≈.50) and the selection ratio is low—few candidates are hired.
Define base rate, selection ratio, and validity coefficient in one conceptual chunk.
Base rate: % of applicants who would succeed without testing. Selection ratio: % of applicants hired. Validity coefficient: Strength of predictor–criterion link. High validity + moderate base rate + low selection ratio = optimal hiring accuracy.
What are trainability tests and when are they used?
Work samples combining a brief training session and subsequent evaluation; used to predict learning potential in untrained applicants.
What problem does the forced-choice method address?
Reduces rater biases (leniency, halo) by requiring raters to choose among equally favorable options.
When is BARS preferred?
When the goal is developmental feedback—anchors describe concrete behaviors tied to performance levels.
What bias does forced distribution correct and how?
Corrects leniency bias by forcing ratings into fixed proportions across categories (e.g., top 10%, middle 70%).
Why is the critical incident technique limited?
Focuses on extreme behaviors, offering poor representation of typical job performance.
Contrast Maslow, Herzberg, Alderfer (ERG), and Expectancy theories.
Maslow: Needs progress upward (physiological → safety → love → esteem → self-actualization). Alderfer (ERG): Condenses to Existence, Relatedness, Growth; regression possible. Herzberg: Hygiene factors prevent dissatisfaction; motivators (achievement, growth) create satisfaction. Expectancy (Vroom): Motivation = Expectancy × Instrumentality × Valence.
According to equity theory, which inequity most affects motivation?
Perceived underpayment—leads to reduced effort or withdrawal; overpayment has weaker effects.
What combination of goal characteristics best increases performance?
Specific, moderately difficult goals with ongoing performance feedback (Locke & Latham).
Why do pay bonuses often fail to sustain motivation?
Financial incentives are extrinsic hygiene factors; without intrinsic motivators (Herzberg), satisfaction and motivation remain low.
According to Fiedler, what determines leader effectiveness?
Match between leader’s fixed style (task vs. relationship oriented) and situational favorableness (leader–member relations, task structure, position power).
Hersey–Blanchard situational leadership: match follower maturity with leader style.
Low ability/low motivation → Telling. High motivation/low ability → Selling. High ability/variable motivation → Participating. High ability/high motivation → Delegating.
How does Vroom–Yetton–Jago’s model determine decision style?
Uses a decision tree of situational questions (importance, time, information quality) to choose between autocratic, consultative, or group decisions.
What is the central idea of House’s Path–Goal Theory?
Leaders enhance motivation by clarifying paths to goals, removing obstacles, and matching style (directive, supportive, participative, achievement-oriented) to worker and task.
Research on gender and leadership style: key finding?
Women generally use more democratic and participative approaches; men slightly more autocratic, with no consistent performance difference.
Why does TQM often fail?
Lack of genuine employee involvement in decision-making undermines commitment to quality initiatives.
What is the focus of process consultation?
Improving group functioning by helping members recognize and modify dysfunctional interaction patterns.
Which change strategy emphasizes collaboration and shared norms?
Normative–reeducative approach—change occurs through redefining norms and relationships.
What distinguishes mediation from arbitration?
Mediation facilitates voluntary agreement by introducing alternatives; arbitration imposes a binding decision.
What characterizes Tuckman’s “norming” stage?
Cohesion, trust, and commitment to group goals emerge after initial conflict.
