Erik Erikson developed the idea behind identity vs. role confusion, which comes from his theory of psychosocial development.

Erikson's theory proposed eight stages: trust vs. mistrust, autonomy vs. shame, initiative vs. guilt, competence vs. inferiority, identity vs. role confusion, intimacy vs. isolation, generativity vs. stagnation, and integrity vs. despair.

Generativity vs. despair is not one of the stages of psychosocial development. Generativity vs. stagnation and integrity vs. despair are two stages of Erikson's theory. 

The stage known as "intimacy vs. isolation" takes place during the period of young adulthood, roughly encompassing ages 18-35. The young woman in the question falls firmly within this range.

Erikson would say that this boy is at the developmental stage during which he is grappling with his own autonomy. This stage is known as "autonomy vs. shame and doubt," and typically takes place during ages 1-3 years.

Relational aggression typically involves more covert behavior, such as spreading rumors or gossiping about others in an attempt to manipulate one's friendships and faciltation exclusion. This type of aggression is represented in the given question.

Physical aggression involves physical harm to another person, such as hitting, punching, kicking, or even vandalizing or damaging one's property. 

There is no such thing as nonverbal aggression. 

Reactive aggression is typically an angry, defensive response to provocation, particularly when one is blocked from reaching a goal or is harmed first. 

Marcia's theory pertaining to identity development and statuses involves two dimensions: exploration and committment. 

Individuals who are actively exploring their options before making a final decision, such as the young man described in this question, are classified in the moratorium identity status. 

Individuals who have made a decision after active exploration as classified in the achievement identity status. 

Individuals who make a decision without doing any exploration are classified in the foreclosure identity status. 

Individuals who do not know what they want to do and who are indifferent to exploring are classiged in the diffusion identity status. 

Since adolescence is characterized by various biological, social, emotional and cognitive changes, Erikson would argue that adolescents are attempting to solidify their identity in terms of who they are, what they value, and what their goals are. If adolescents do not resolve their identity crises, they could have role confusion, which has negative psychological implications. 

Intimacy vs. isolation characterizes early adulthood. 

Industry vs. inferiority characterizes middle childhood. 

Initiative vs. guilt characterizes early childhood.

The glass ceiling effect is the phenomenon that occurs when women can no longer advance in their careers for higher-level positions that are typically held by men. 

A self-fulfilling prophecy and stereotype threat are very similar in that they typically are the result of stereotypes that negatively impact one's academic performance. 

Increase in self-confidence is a distractor item, and does not directly relate to the question. 

Men are more likely than women to select mates based on physical attractiveness. According to evolutionary theory, men focus on whether a woman is physically healthy and fit to carry children.

Income level and intelligence are traits that women actually value. Family stability was a distractor item, and does not directly relate to the question.

Social comparisons are chracteristic of middle childhood when children begin to notice their relative strengths and weaknesses in comparison to their friends and classmates.
