Final answer:
Lynn is most likely an industrial/organizational (I-O) psychologist as her research on the effect of downsizing on morale aligns with the study of employee and workplace interactions and changes within an organization.
Step-by-step explanation:
Lynn, who has just received a research grant to study the effect of downsizing on morale at a large computer company, is most likely an industrial/organizational (I-O) psychologist. Industrial psychology, a branch within I-O psychology, focuses on understanding job characteristics, assessing applicants, and methods for matching individuals to jobs like evaluating the impact of downsizing on employee morale.
Organizational psychology, the other branch of I-O psychology, might explore how these downsizing events influence organizational culture, employee relationships, and overall company productivity. Industrial and organizational psychologists are pertinent in managing changes within an organization, such as downsizing or mergers, because they understand the profound effects these events can have on employee morale and organization effectiveness.
