Final answer:
The term for the trait that indicates how easily a person gets along with others is agreeableness, a dimension of the Five Factor Model of personality which includes friendliness and cooperation.
Step-by-step explanation:
The term for the trait characterized by the ease with which a person gets along with others is agreeableness. This trait is part of the Five Factor Model of personality, which includes other dimensions such as conscientiousness, neuroticism, openness, and extraversion. Individuals who score high in agreeableness tend to be friendly, cooperative, and sympathetic. These people generally find it easier to form harmonious relationships with others and are often seen as pleasant and good-natured.
Trait theorists suggest that personality is composed of characteristic ways of behaving. Agreeableness specifically encompasses elements such as patience, tolerance, gentleness, and a general disposition towards being cooperative and trustworthy. It is one of the central traits that define how we interact with others in our environment. Continuing research in psychology seeks to understand how these traits manifest in our behaviors and impact various aspects of our lives such as career success and social relationships.
