Final answer:
The question pertains to strategies for changing ideas within the self and with many people, which are correctly labeled as Personal and Social strategies. Social psychology studies both personal intrapersonal processes and interpersonal group dynamics within a social context.
Step-by-step explanation:
The correct answer to the question is b) Personal; Social. When discussing strategies that focus on changing ideas within the self, we are referring to personal strategies. These include changes in a person's emotions, attitudes, beliefs, and ways of thinking. On the other hand, social strategies refer to interventions focused on a broader level, influencing many individuals within groups or whole communities. This could involve helping behaviors, addressing prejudice and discrimination, or enhancing group processes and intergroup relationships.
Social psychology investigates both personal (intrapersonal) and social (interpersonal) aspects of behavior within a social context. It studies how environmental and situational factors interact with internal processes to guide an individual's behavior. Concepts like socialization pertain to how individuals internalize societal norms and values, which is inherently a personal process, but it also has a social component as it guides interactions with others.
When it comes to group behavior, individuals exhibit both instrumental and expressive behaviors. Instrumental behaviors are goal-oriented and rational, while expressive behaviors express emotions or symbolic aspects of the self within a group context. Both personal and social strategies can influence these behaviors, although at different levels of interaction and with varying scopes of impact.
