Jean Piaget's theory of cognitive development suggests that infants in the sensorimotor stage are inherently egocentric. This means they lack the ability to differentiate between themselves and the external world, perceiving everything from their own immediate perspective. This 'self-centered' orientation is a natural developmental phase before the child learns to understand the viewpoints of others.

A master status is the primary social position that defines an individual's identity in a specific social context. In this scenario, the students define the professor primarily by his role as an 'excellent instructor' rather than his physical or demographic traits.

Sigmund Freud proposed that the human psyche is divided into three parts. The ego functions as the rational, conscious component that mediates between the primal desires of the id and the moral constraints of the superego. It operates on the reality principle, ensuring that an individual's behavior is socially acceptable and practical in the real world.

Elisabeth Kübler-Ross identified five stages of grief that individuals often experience when facing terminal illness or significant loss. These include denial, anger, bargaining, depression, and acceptance. The options provided represent three of these core stages, making 'all of the above' the correct selection.

In the majority of modern legal systems, the age of majority is set at eighteen. This milestone marks the transition from childhood to legal adulthood, granting individuals the rights and responsibilities of an adult, such as the right to vote, enter into binding contracts, and be held fully accountable under criminal law.

A self-fulfilling prophecy occurs when an initial false definition of a situation evokes a new behavior that makes the originally false conception come true. In this case, the label of 'lazy' or 'unintelligent' influences the child's self-concept and effort, leading to the predicted poor academic performance.

Richard Jenkins argues that the self is not merely a cognitive or abstract construct but is deeply rooted in the physical body. He suggests that sociological analysis must account for how the physical presence and embodiment of individuals are central to the formation and expression of the social self.

Latent functions are the unintended or hidden consequences of social institutions. While the manifest function of school is academic instruction, the latent functions include teaching children social skills like teamwork, the importance of punctuality through following schedules, and the habit of using standardized tools like textbooks.

The educational system serves as a primary agent of secondary socialization. Beyond academic learning, schools teach societal norms, values, and roles, preparing individuals to function effectively within the broader social structure and workforce.

Cultural transmission is the process by which culture is passed from one generation to the next. This occurs through formal education (schools) and informal education (family, peers, and daily social interactions), both of which are essential for socialization.
