Final answer:
The study of social psychology examines how social influences, actor-observer bias, self-efficacy, informational social influence, and collective behavior shape human interactions and behavior.
Step-by-step explanation:
The subject in question, social psychology, explores how different factors influence helping behavior, as well as the role of social influence, collective behavior, and social roles in human interactions. Social psychology examines such concepts as the actor-observer bias, where individuals tend to attribute their own behavior to situational influences and others' behavior to dispositional influences, and the self-efficacy level, which affects our confidence in our abilities and our approach to challenges.
In regards to situations that foster informational social influence, it is more likely to occur when the answer to a situation is unclear and the group involved is perceived to have expertise. Additionally, collective action problems are considered to be less severe in small groups due to the increased ability to monitor behavior, the inability for individuals to 'free-ride,' and the strength of peer pressure.
Finally, social cues are a significant aspect of social psychology, providing individuals with information on how to behave in specific circumstances. This can be seen in social roles, social norms, and scripts that dictate expected behaviors in various situations.
