Final answer:
The main concerns of industrial and organizational psychology are personnel matters, human resource concerns, personality traits, and their impact on work. Industrial psychology handles hiring and employee evaluation, while organizational psychology deals with employee relationships and culture. Human factors psychology focuses on optimizing the design of tools and workplaces for safety and efficiency.
Step-by-step explanation:
Industrial and organizational psychology (I-O psychology) is the study of behavior in work settings. I-O psychology is divided into two main areas: industrial psychology, which focuses on hiring, maintaining employees, and evaluating employees' performance, and organizational psychology, which examines employee relationships and organizational culture. Among the main concerns of I-O psychology are personnel matters, human resource concerns, and the effects of personality traits on work and productivity; lifestyle choices are generally less central to the field unless they directly impact work behavior and productivity.
Industrial psychology is associated with job analysis, applicant testing, performance appraisals, and adherence to legality in hiring practices. Organizational psychology, on the other hand, deals with job satisfaction, the determinants and outcomes of worker satisfaction, management styles, leadership styles, and the prevention of workplace harassment, including sexual harassment. Human factors psychology, also known as ergonomics, specializes in the interaction between workers and their tools, aiming to optimize productivity, safety, and health.
