In psychology, temperament broadly refers to consistent individual differences in behavior that are biologically based and are relatively independent of learning, system of values and attitudes.

Emotional self-regulation or emotion regulation is the ability to respond to the ongoing demands of experience with the range of emotions in a manner that is socially tolerable and sufficiently flexible to permit spontaneous reactions as well as the ability to delay spontaneous reactions as needed. It can also be defined as extrinsic and intrinsic processes responsible for monitoring, evaluating, and modifying emotional reactions. Emotional self-regulation belongs to the broader set of emotion regulation processes, which includes both the regulation of one's own feelings and the regulation of other people's feelings.
Prosocial behavior, or intent to benefit others, is a social behavior that "benefit[s] other people or society as a whole", "such as helping, sharing, donating, co-operating, and volunteering". Obeying the rules and conforming to socially accepted behaviors are also regarded as prosocial behaviors. These actions may be motivated by empathy and by concern about the welfare and rights of others, as well as for egoistic or practical concerns, such as one's social status or reputation, hope for direct or indirect reciprocity, or adherence to one's perceived system of fairness. It may also be motivated by altruism, though the existence of pure altruism is somewhat disputed, and some have argued that this falls into philosophical rather than psychological realm of debate. Evidence suggests that pro sociality is central to the well-being of social groups across a range of scales, including schools. Prosocial behavior in the classroom can have a significant impact on a student's motivation for learning and contributions to the classroom and larger community. In the workplace, prosocial behaviour can have a significant impact on team psychological safety, as well as positive indirect effects on employee's helping behaviors and task performance. Empathy is a strong motive in eliciting prosocial behavior, and has deep evolutionary roots.
Empathic concern refers to other-oriented emotions elicited by, and congruent with the perceived welfare of, someone in need. These other-oriented emotions include feelings of tenderness, sympathy, compassion and soft-heartedness.

In psychology, personal distress is an aversive, self-focused emotional reaction to the apprehension or comprehension of another's emotional state or condition. This negative affective state often occurs as a result of emotional contagion when there is confusion between self and other. Unlike empathy, personal distress does not have to be congruent with the other's state, and often leads to a self-oriented, egoistic reaction to reduce it, by withdrawing from the stressor, for example, thereby decreasing the likelihood of prosocial behavior. There is evidence that sympathy and personal distress are subjectively different, have different somatic and physiological correlates, and relate in different ways to prosocial behavior.
Some of the research that is conducted in the field of psychology is more "fundamental" than the research conducted in the applied psychological disciplines, and does not necessarily have a direct application. The subdisciplines within psychology that can be thought to reflect a basic-science orientation include biological psychology, cognitive psychology, neuropsychology, and so on. Research in these subdisciplines is characterized by methodological rigor. The concern of psychology as a basic science is in understanding the laws and processes that underlie behavior, cognition, and emotion. Psychology as a basic science provides a foundation for applied psychology. Applied psychology, by contrast, involves the application of psychological principles and theories yielded up by the basic psychological sciences; these applications are aimed at overcoming problems or promoting well-being in areas such as mental and physical health and education.

Moral development focuses on the emergence, change, and understanding of morality from infancy through adulthood. The theory states that morality develops across a lifespan in a variety of ways and is influenced by an individual's experiences and behavior when faced with moral issues through different periods of physical and cognitive development. Morality concerns an individual's reforming sense of what is right and wrong; it is for this reason that young children have different moral judgment and character than that of a grown adult. Morality in itself is often a synonym for "rightness" or "goodness." It also refers to a specific code of conduct that is derived from one's culture, religion, or personal philosophy that guides one's actions, behaviors, and thoughts.
Amy Gene Halberstadt is an American psychologist specializing in the social development of emotion. She is currently Alumni Distinguished Undergraduate Professor of Psychology at North Carolina State University in Raleigh, North Carolina, and is an editor of the journal Social Development.
Social emotions are emotions that depend upon the thoughts, feelings or actions of other people, "as experienced, recalled, anticipated or imagined at first hand". Examples are embarrassment, guilt, shame, jealousy, envy, elevation, empathy, and pride. In contrast, basic emotions such as happiness and sadness only require the awareness of one's own physical state. Therefore, the development of social emotions is tightly linked with the development of social cognition, the ability to imagine other people's mental states, which generally develops in adolescence. Studies have found that children as young as 2 to 3 years of age can express emotions resembling guilt and remorse. However, while five-year-old children are able to imagine situations in which basic emotions would be felt, the ability to describe situations in which social emotions might be experienced does not appear until seven years of age.
