Needs are fundamental elements of human motivation, expressing essential or important desires or strivings that may be either biological or psychosocial. They are basic drivers that can elicit action or behavior aimed at meeting certain conditions or achieving certain goals.
Needs play a key role in shaping the motivational structure of personality and can influence goal choice, decision-making, and the formation of values. They may be internal, that is, arising from internal physiological or psychological states, or external, shaped by the sociocultural environment and external stimuli. Responses to needs may vary and depend on individual characteristics, circumstances, and context.
