Which of the following professionals focuses on improving organizational structure and efficiency?

The professional that focuses on improving organizational structure and efficiency is an organizational psychologist. This field of psychology is specifically designed to study human behavior in workplace settings and apply psychological principles to enhance organizational performance. Organizational psychologists analyze various factors within organizations, such as employee motivation, leadership styles, team dynamics, and job satisfaction, to devise strategies that lead to improved productivity and employee well-being.

In this role, they may assess the effectiveness of management practices, develop training programs, and facilitate changes in organizational culture—all aimed at making the organization function more effectively. Their expertise is crucial for companies aiming to enhance their operational efficiencies and overall work environment.

The other professionals mentioned, such as clinical psychologists, developmental psychologists, and cognitive psychologists, focus on different areas. Clinical psychologists primarily deal with diagnosing and treating mental health issues, developmental psychologists study developmental changes across the lifespan, and cognitive psychologists investigate mental processes such as perception, memory, and decision-making. Each of these roles plays an important part in psychology but does not target organizational improvement in the way that organizational psychologists do.
