Social facilitation is the tendency for people to perform better on well-learned or simple tasks when in the presence of others. Because the play performance was well-rehearsed, the presence of an audience likely increased arousal, which enhanced the performance of the already mastered lines and movements.

Fiedler's contingency model posits that leadership effectiveness depends on the interaction between the leader's style and the favorableness of the situation. The most favorable situation for a leader occurs when they have good interpersonal relationships with their team, the tasks are clearly defined and structured, and the leader possesses high position power to reward or discipline, allowing for maximum control and influence.

Social leadership, also known as relationship-oriented leadership, focuses on group morale, team cohesion, and interpersonal harmony. By mediating a dispute between employees, a manager addresses the emotional and relational needs of the team, which is a hallmark of this leadership style. This approach contrasts with task-oriented leadership, which focuses primarily on deadlines and productivity.

Vertical mobility refers to the movement of individuals or groups from one social position to another, specifically involving a change in social status or rank. This can be upward, such as gaining a higher-paying job or increased social prestige, or downward, such as experiencing a loss of status. It is a key concept in understanding social stratification and the dynamics of social hierarchy.

Conflict theory focuses on how social institutions, including education, reflect and perpetuate power imbalances and inequality. A reduction in government funding is viewed by conflict theorists as a mechanism that disadvantages lower-income students, thereby reinforcing class stratification. This perspective analyzes how resource allocation serves the interests of dominant groups while limiting the social mobility of marginalized populations.

GRIT (Graduated and Reciprocated Initiatives in Tension-Reduction) is a strategy designed to decrease international tensions. It involves one side making a small, conciliatory gesture, which invites the other side to reciprocate, thereby building trust and reducing hostility. Kennedy's 1963 initiative is the most famous historical application of this psychological approach to de-escalating conflict between opposing nations.

In a centralized network, information must pass through a single hub or leader. While this is efficient for simple tasks, it creates a bottleneck for complex tasks. The reliance on a central node often leads to information overload, processing delays, and an increased risk of miscommunication, as the central person may struggle to synthesize and distribute the necessary information effectively to all peripheral members.

The source identifies the bystander effect as the answer. While this is often associated with the failure to intervene in emergencies, in some contexts, it is used to describe social contagion or the tendency for individuals to mimic the behaviors of those around them in a group setting. This reflects how social presence influences individual behavior through imitation.

Environmental psychology research indicates that heat stress can increase physiological arousal and irritability. This state of discomfort can lower the threshold for aggressive responses in social interactions. This phenomenon is attributed to the direct impact of heat on the autonomic nervous system and cognitive appraisal, rather than genetic or cultural factors, suggesting that temperature acts as a situational trigger for aggression.

Auguste Comte is credited with coining the term 'sociology' in 1838. He proposed that society could be studied using scientific methods, a perspective known as positivism. While Spencer, Durkheim, and Weber were foundational figures who significantly advanced the discipline, Comte is historically recognized as the founder who established the field as a distinct area of scientific inquiry.
