A moral panic occurs when a condition, episode, person, or group of persons emerges to be defined as a threat to societal values and interests. This phenomenon is characterized by an intense, disproportionate reaction from the media, public, and authorities, often leading to heightened social anxiety and calls for stricter control measures against the perceived threat.

Parents often use distinct, sharp, or rhythmic vocalizations to capture an infant's attention or to signal a warning regarding potential danger. These sounds are effective because they stand out from normal speech patterns, helping the infant recognize that the parent is communicating an urgent message or alerting them to avoid a specific action or object that might be harmful.

Vertical mobility refers to the movement of individuals or groups up or down the social hierarchy. This movement involves a change in social class or status, such as moving from a lower-income job to a higher-income job, or vice versa. It is a key indicator of the openness and fluidity of a society's stratification system.

Philip Zimbardo led the 1971 Stanford Prison Experiment, a landmark study in social psychology. It examined how individuals conform to assigned roles in a simulated prison environment, demonstrating how situational factors can significantly influence human behavior and lead to abusive actions when power dynamics are unbalanced.

Milgram's experiment was designed to measure the extent to which individuals would obey an authority figure's instructions to inflict pain on another person. The 'teacher' was instructed to administer an electric shock of increasing intensity to the 'learner' every time they made a mistake. This setup was crucial for testing the limits of human obedience to authority, even when the task involved causing perceived harm.

Conformity is a type of social influence involving a change in belief or behavior in order to fit in with a group. This change is in response to real or imagined group pressure, where individuals adjust their actions to match the perceived standards of the majority.

The reciprocity norm is a social rule that dictates that people should return favors or kindnesses received from others. This norm is a fundamental aspect of social interaction, as it helps build trust and maintain cooperative relationships within a society. It suggests that if someone does something for you, you are socially obligated to return the favor, which encourages mutual support and social cohesion.

Edwin Sutherland is famous for developing the 'Differential Association Theory.' He argued that criminal behavior is not inherited or solely the result of personality traits, but is learned through social interaction with others who hold definitions favorable to the violation of the law. This theory remains a cornerstone of sociological criminology.

Max Weber identified charismatic authority as one of his three types of legitimate authority. This form of power is not based on tradition or legal rules, but rather on the perceived extraordinary qualities of an individual leader. Followers are drawn to the leader's personality, which creates a strong emotional bond and inspires them to follow the leader's vision or commands without question.

The societal-reaction approach is widely known as Labeling Theory. This perspective suggests that deviance is not inherent in an act itself, but rather a consequence of how others perceive, define, and respond to that act. When society labels an individual as deviant, that label can become a self-fulfilling prophecy, influencing the individual's self-concept and future behavior, thereby reinforcing the social reaction to their perceived non-conformity.
