Final answer:
An I-O psychologist aims to increase job satisfaction and productivity by examining and improving the work environment, hiring processes, training programs, and performance appraisals.
Step-by-step explanation:
A psychologist working to increase job satisfaction and productivity within a company is likely trained in Industrial and Organizational (I-O) Psychology. This field encompasses both industrial psychology, focused on aligning job characteristics with applicant attributes and improving hiring, training, and performance appraisal systems, and organizational psychology, which delves into the social aspects of the workplace, including job satisfaction, management styles, leadership, and organizational culture. Enhancing these factors can lead to increased productivity and a more efficient workplace.
