This question evaluates outcomes of intergroup bias escalation. Social identity can escalate bias through selective recall and stereotyping, especially in competitive settings. Residents circulate negative messages and interpret behaviors disrespectfully, fueled by floor pride. Choice A is correct as it captures bias escalation via stereotyping. Choice B is incorrect because competition does not increase empathy here; it heightens conflict. For analogous dynamics, identify bias amplification cues like avoidance. Consider how comparisons reinforce negative out-group perceptions.

Social identity theory posits a three-step process. The first step is social categorization, where an individual categorizes themselves and others into social groups (e.g., 'I am a student'). This is followed by social identification, where they adopt the identity of the group, and then social comparison, where they compare their group favorably to others to maintain self-esteem. Social mobility is a strategy for dealing with a low-status group identity, not an initial step in its formation.

Social identity theory suggests that a portion of an individual's self-concept and self-esteem is derived from their perceived membership in relevant social groups. The success of one's in-group (the university) can enhance one's own self-esteem, a concept known as 'basking in reflected glory.' This directly links social identity (group membership) to self-esteem.

A reference group is a group that individuals use as a standard for evaluating themselves and their own behavior. An aspirational reference group is a group that an individual is not a part of but hopes to join. The student is using the popular clique as a standard and emulating their behavior with the goal of future membership.

In-group favoritism (or in-group bias) is the tendency to favor one's own group over other groups. This favoritism can manifest as attributing more positive characteristics to in-group members and distributing more resources to them. Believing one's own nationality is superior to others is a clear example of this cognitive bias.

The core distinction lies in the nature of the relationships. Primary groups (e.g., family, close friends) are characterized by close, personal, enduring relationships (expressive ties). Secondary groups (e.g., a sociology class, a workplace) are larger, more impersonal, and often temporary, formed to achieve a specific goal (instrumental ties).

Role conflict occurs when there is a clash between the responsibilities and expectations associated with two or more different statuses held by the same person. In this case, the individual's status as a 'doctor' conflicts with her status as a 'mother.' Role strain, in contrast, involves conflicting expectations within a single status.

Groupthink is a psychological phenomenon that occurs within a group of people in which the desire for harmony or conformity in the group results in an irrational or dysfunctional decision-making outcome. Key symptoms include ignoring alternatives, suppressing dissent, and an illusion of unanimity, which aligns with the board's behavior of overlooking risks to reach a consensus.

In Goffman's dramaturgical analysis, the 'back stage' is where an individual is free from the expectations and scrutiny of their 'audience' and can therefore drop their 'front stage' performance. It is a private region where they can be their authentic self, relax, and prepare for future public performances. Options A, B, and D all describe aspects of the 'front stage' self.

Social loafing is the phenomenon of a person exerting less effort to achieve a goal when they work in a group than when they work alone. It is often explained by the diffusion of responsibility among group members and the perception that individual contributions are not being monitored or evaluated, as is the case in this scenario.
