Traditional marriages include men and women assuming typical gender roles where the husband is the "breadwinner" and the wife is the "homemaker." On the other hand, egalitarian marriages involve men and women taking on and balancing roles and responsibilities within the family and at work.

As the adult child, an individual often fulfills the role of parent and caretaker for two generations, which is called the "sandwich generation." The remaining choices are distractors. 

Kubler-Ross developed an explanation for the series of stages people go through when faced with their own death. According to this model, most people experience the stages in the following order: denial, anger, bargaining, depression, and acceptance. One way to remember this is by the acronym DABDA. Note that shame and anxiety are not stages in this model. 

Jane's parents are authoritative, meaning they set high standards for their children but are also flexible and reasonable. Authoritarian parents tend to set high standards, but are not warm or responsive. They expect obedience and leave little room for negotiation. Permissive parents can be warm and responsive, but have few rules for their children. Secure is not a term used to describe parenting style. Rather, it describes attachment. Securely attached children are distressed when their parents leave the room but welcome them on their return. Authoritative parents often raise secure children. Ambivalent children are distressed when their parents leave but are not welcoming when they return. 

Cooperative play is the most advanced stage of play in which a child is interested in both other children and the play activity. Some examples of cooperative play include "freeze tag" and "red rover." 

According to Erik Erikson's psychosocial stages, adolescents are faced with how they appear to others (especially same-age peers) and take this time to "try on" different roles to see how others react. This stage is completed when the individual has adopted a comprehensive identity. 

Lawrence Kohlberg developed three levels of morality to describe people: pre-conventional, conventional, and post-conventional thought. Pre-conventional thought is the most elementary of the three levels, in which actions are thought to be good or bad based on the rewards or punishments that stem from said action. 

Lawrence Kohlberg was the theorist who developed the concept that morality comes in three stages: pre-conventional, conventional, and post-conventional.

In the conventional stage of moral development, right vs. wrong is based upon societal conventions and expectations. Since Cody stated something that is a social convention, rather than a personal ethical belief, he is demonstrating features of the conventional stage of devlopment.

At stage three of Kohlberg's theory, which usually begins in adolescence or adulthood, people become conscious of how the society at large views their behavior. Thus, they are not necessarily concerned with gaining a direct reward or avoiding punishments, but rather focus on cultivating behaviors like appreciation and good manners that will make them well-liked by society. This stage is defined by conformity to societal expectations of behavior.
