Final answer:
Individual factors such as knowledge, skills, attitudes, and genetics are personal characteristics that influence behavior and are distinct from social or environmental influences.
Step-by-step explanation:
The correct answer is Individual factors, such as knowledge and skills, attitudes, genetics. Individual factors encompass a person's unique characteristics that influence their behavior, including psychological aspects and genetic makeup. In social psychology, situational factors are more of the focus (2.D.1), which means the settings and circumstances that impact a person's behavior. From a sociological perspective, gender and class are considered influential in a person's socialization, but other elements like personal choices and selective migration (20.a) affect where people decide to live based on their needs and personality. Personality psychologists are notably interested in the interplay between cultural factors and genetics when evaluating personality traits. Furthermore, environmental factors have a significant role in the expression of genotypes (4.C.2) and population dynamics (4.C.3).
