The displacement hypothesis suggests that when an individual cannot express aggression toward the actual source of their frustration, they redirect that energy toward a safer or more accessible target. This mechanism is intended to reduce internal tension. While related to the catharsis concept, the specific term used in the source is displacement, which focuses on the redirection of the target of the aggressive impulse.

Attitudes are evaluative judgments formed toward objects, people, or ideas. In Lewinian field theory, the 'life-space' represents the totality of facts that determine the behavior of an individual at a certain moment, encompassing all objects and events that have psychological significance to the person.

Daryl Bem's self-perception theory suggests that individuals develop their attitudes by observing their own behavior and the circumstances under which it occurs. When Mary observes that she voluntarily attends theater class and performs well, she infers that she must enjoy the subject. This theory posits that we often act as outside observers of our own actions to determine our internal states and preferences.

Émile Durkheim, a founding figure in sociology, emphasized the importance of the comparative method. He argued that sociology should move beyond mere description of social phenomena to provide causal explanations of social facts, thereby establishing a rigorous scientific framework for the discipline.

Research in social psychology consistently demonstrates the 'self-serving bias,' where individuals tend to perceive themselves in a positive light. Most people believe they possess more desirable traits and are less prone to common errors than the average person. This tendency to view oneself favorably compared to others serves to protect self-esteem and maintain a positive self-concept, even when objective evidence might suggest otherwise in various social and personal domains.

Schemas are cognitive frameworks that help us organize and interpret information. They are highly functional because they save cognitive energy, aid in memory retrieval, rely on past experiences to predict future events, and can trigger emotional responses, making them essential for navigating complex social environments.

The Implicit Association Test is a psychometric tool designed to detect the strength of a person's automatic association between mental representations of objects in memory. It is most widely used to measure unconscious biases and stereotypes that individuals may hold but are not consciously aware of or willing to report, providing insight into implicit social cognition.

The halo effect is a cognitive bias where an observer's overall impression of a person influences how they feel and think about that person's character in specific areas. If an individual is perceived as having one positive trait, such as being physically attractive or punctual, others often incorrectly assume they possess other positive traits, such as high intelligence, even without evidence to support that conclusion.

Refuting an argument involves the active use of logic and evidence to counter opposing viewpoints. By systematically addressing and dismantling the claims of an opponent, an individual effectively defends their own position. This process is essential in critical thinking and debate, as it allows one to maintain their stance while demonstrating an understanding of the logical inconsistencies in the opposing perspective.

Discrimination refers to actions or behaviors that disadvantage certain groups, while prejudice refers to negative attitudes or beliefs about those groups. This distinction highlights the importance of recognizing that prejudice is primarily a cognitive and affective phenomenon, whereas discrimination is the behavioral outcome of those underlying attitudes.
