Final answer:
Psychologists study information systems to understand their impact on individuals and organizations, focusing on cognitive processes and workplace dynamics, as well as human-machine interactions through cognitive, industrial, and organizational psychology. The correct option is A.
Step-by-step explanation:
Psychologists study information systems with an eye to understanding how these systems affect individuals, groups, and organizations.
In particular, cognitive psychology explores the relationship between human thinking and behavior, while industrial and organizational psychology examines job requirements, employee evaluations, and workplace dynamics, also addressing legalities such as discrimination in hiring.
Organizational psychology looks at the effects of social interactions within the workplace on worker satisfaction and organizational productivity. In the realm of human factors psychology or ergonomics, the focus is on optimizing the interface between workers and their work tools to enhance productivity, safety, and health, such as designing ergonomic workstations or studying human-software interactions.
Hence, Option A is correct.
