Final answer:
An HR Specialist is someone who knows a lot about a specific HR function. An expressive leader, such as the director of a summer camp for chronically ill children, typically fosters group harmony. A personality psychologist would research what makes an employee well-suited for a job.
Step-by-step explanation:
The role that typically knows a lot about a specific Human Resources (HR) function would be best defined as an HR Specialist. An HR Specialist focuses deeply on a particular area of HR, such as recruiting, benefits, or employee relations, and thus gains extensive knowledge in that specific domain. In contrast, an HR Generalist would have a broad understanding of many HR functions, an HR Analyst would focus on the data and analytics side of HR, and an Executive HR Manager would oversee the strategic direction and management of the HR department.
Regarding the second part of the question:
- The individual more likely to be an expressive leader is c. The director of a summer camp for chronically ill children. Expressive leaders are often those who maintain group harmony and morale, and the nature of a camp for chronically ill children would likely require a high degree of emotional intelligence and the ability to foster a positive community environment.
In terms of the third part:
A researcher interested in the factors that make an employee best suited for a given job is likely to identify as a personality psychologist. Personality psychologists study individual differences and how these affect a person's suitability for various occupations.
