Concept
Repetition time (TR) is a crucial parameter in magnetic resonance imaging (MRI) that refers to the time interval between successive pulse sequences applied to the same slice. It influences the contrast and signal-to-noise ratio of the image, playing a significant role in determining the type of tissue contrast obtained in MRI scans.

Concept
Conformity is the act of aligning one's beliefs, attitudes, and behaviors with those of a group or social norms, often driven by the desire for acceptance or fear of rejection. It plays a crucial role in social cohesion but can also lead to the suppression of individuality and critical thinking.
Concept
Social norms are the unwritten rules that govern behavior in society, influencing how individuals act and interact within their cultural context. They shape expectations, promote conformity, and can vary significantly across different communities and cultures, affecting everything from daily interactions to broader societal structures.
Concept
Group dynamics refers to the behavioral and psychological processes that occur within a social group or between groups, influencing how they interact, make decisions, and achieve goals. Understanding these dynamics is crucial for enhancing group performance, resolving conflicts, and fostering a positive and productive group environment.
Concept
Social pressure is the influence exerted by society or a social group on individuals to conform to expected norms, behaviors, or attitudes. It can lead to changes in beliefs and actions, often driven by the desire for acceptance, fear of rejection, or perceived authority.
Concept
Normative influence occurs when individuals conform to the expectations of others to gain social approval or avoid social disapproval. It plays a crucial role in shaping behaviors and attitudes within groups, often leading to conformity even when the group's view conflicts with personal beliefs.
Concept
Informational influence occurs when individuals conform to the behaviors or beliefs of others because they perceive them as sources of accurate information, especially in ambiguous situations. This type of social influence is driven by the desire to make correct decisions and is often observed when people lack confidence in their own knowledge or judgment.
Concept
The Asch Conformity Experiments demonstrated the power of social influence, showing that individuals often conform to group opinions even when they are clearly incorrect. These experiments highlighted the tension between individual judgment and group pressure, revealing the extent to which social dynamics can shape perception and decision-making.
Concept
Social Identity Theory posits that a person's self-concept is derived from perceived membership in social groups, influencing their behavior and attitudes. This theory explains intergroup behavior, highlighting how in-group favoritism and out-group discrimination arise from the need for positive self-esteem and Social Identity.
Concept
Groupthink is a psychological phenomenon where the desire for harmony and conformity within a group results in irrational or dysfunctional decision-making outcomes. It often leads to the suppression of dissenting viewpoints, causing the group to overlook potential risks and alternative solutions.
Concept
Predominance refers to the state or condition of being greater in number, strength, influence, or importance compared to others. It often involves a hierarchical structure where one entity or idea holds more power or significance than its counterparts, shaping dynamics and outcomes in various contexts.
Concept
The Spiral of Silence theory, proposed by Elisabeth Noelle-Neumann, suggests that individuals are less likely to express their opinions if they perceive themselves to be in the minority, due to fear of isolation or reprisal. This creates a self-reinforcing cycle where dominant opinions become more prevalent, while minority views are further marginalized, potentially skewing public discourse and perception of majority opinion.
Concept
Jury dynamics refers to the complex interplay of individual biases, communication style, group pressure, and decision-making processes that influence how a jury reaches a verdict. Understanding Jury dynamics is crucial for legal professionals as it helps in jury selection, predicting outcomes, and formulating legal strategies to sway or counteract potential biases.
