Study Notes
I/O Psychology
- Industrial/Organizational (I/O) psychology applies psychological principles to understand and improve human behavior in the workplace.
- Focuses on topics like employee selection, training, performance appraisal, and organizational development.
History of I/O Psychology
- I/O Psychology emerged during the Industrial Revolution with the need to improve workplace efficiency.
- Time and motion studies analyzed efficient work movements to enhance productivity.
- Frederick W. Taylor's scientific management emphasized efficiency, standardization, and worker selection.
- Focused on increasing economic efficiency and labor productivity.
Validity and Reliability in Measurement
- Reliability: Consistency of a measure. A reliable test produces similar results under consistent conditions.
- Validity: Accuracy of inferences drawn from test scores, measuring what it claims to measure. Valid tests accurately reflect the underlying construct.
- Types of Validity:
- Concurrent Validity: Assesses how well a test aligns with existing measures of the same construct.
- Predictive Validity: Measures how well a predictor forecasts future performance.
- Construct Validity: Evaluates how well a test measures the theoretical concept it aims to measure.
- Convergent Validity: Measures how well two measures of the same construct correlate.
- Divergent Validity: Assesses how weakly two measures of different constructs correlate.
Knowledge, Skills, Abilities, and Other Characteristics
- Knowledge: Acquired through education, training, or experience.
- Skills: Acquired through practice and experience, enabling specific task performance. (e.g., typing speed, operating machinery).
- Abilities: Innate characteristics influencing task performance. Cognitive abilities (reasoning, problem-solving), physical abilities (strength, coordination).
- Other Characteristics: Personality traits, work styles, and personal attributes influencing job environment interaction.
Job Analysis Hierarchy
- Tasks: The lowest level, specific units of work towards achieving a job objective (e.g., typing a document, answering a phone call).
- Positions: A set of tasks performed by a single employee.
- Jobs: Similar positions grouped together based on task similarity and required skills.
- Job Families: Groups of similar jobs sharing characteristics.
Assessment of Individual Differences
- Computerized Adaptive Testing (CAT): Customizes test difficulty based on individual performance, providing a more personalized assessment.
- Online Tests: Provide efficiency and accessibility for assessing cognitive abilities, personality traits, and emotional intelligence.
- Interviews: Used to review job responsibilities, identify employee achievements, and set future goals. Structure influences validity.
Personnel Selection
- Selection Ratio (SR): The ratio of job openings to applicants. (e.g., 4 openings/100 applicants = 0.04 SR).
- A Lower Selection Ratio (SR) Usually Means:
- Higher selectivity in the hiring process, potentially enhancing the value of predictors used in selection.
- Base Rate: Percentage of existing employees judged satisfactory in their roles.
- False Positive: Incorrectly identifying an applicant as suitable when they actually fail to perform well.
- False Negative: Rejecting an applicant who would have been successful in the role.
