Altruism is defined by some evolutionary biologists (e.g., R. Alexander, 1987; W. D. Hamilton, 1964) as behavior that is beneficial to others (or to the group) at a cost to the individual, and many posit individual selection as the mechanism that explains altruism solely in terms of the behaviors of individual organisms acting in their own self ...
Social facilitation is a social phenomenon in which being in the presence of others improves individual task performance. [1] [2] That is, people do better on tasks when they are with other people rather than when they are doing the task alone. Situations that elicit social facilitation include coaction, performing for an audience, and appears ...
Empathy is generally described as the ability to take on another person's perspective, to understand, feel, and possibly share and respond to their experience.

A change is called a Pareto improvement if it leaves at least one person in society better-off without leaving anyone else worse off than they were before. A situation is called Pareto efficient or Pareto optimal if all possible Pareto improvements have already been made; in other words, there are no longer any ways left to make one person ...
The nominal group technique (NGT) is a group process involving problem identification, solution generation, and decision-making. [1] It can be used in groups of many sizes, who want to make their decision quickly, as by a vote, but want everyone's opinions taken into account (as opposed to traditional voting, where only the largest group is considered).

Two types of convergent tasks used were, the first being a remote associates tasks, which gave the subject three words and asked what word the previous three words are related to. The second type of convergent thinking task were insight problems, which gave the subjects some contextual facts and then asked them a question requiring interpretation.
Problems in need of solutions range from simple personal tasks (e.g. how to turn on an appliance) to complex issues in business and technical fields. The former is an example of simple problem solving (SPS) addressing one issue, whereas the latter is complex problem solving (CPS) with multiple interrelated obstacles. [1]
A thesaurus (pl.: thesauri or thesauruses), sometimes called a synonym dictionary or dictionary of synonyms, is a reference work which arranges words by their meanings (or in simpler terms, a book where one can find different words with similar meanings to other words), [1] [2] sometimes as a hierarchy of broader and narrower terms, sometimes simply as lists of synonyms and antonyms.
