Which of the following is not an acquired motive?

Motives in psychology are classified into two broad categories: primary (biogenic) motives, which are innate, unlearned drives rooted in biological survival needs, and secondary (psychogenic/acquired) motives, which are learned through social interaction, culture, and reinforcement over a person's lifetime.

Affiliation, achievement, and approval are all social motives that develop through upbringing, cultural conditioning, and repeated reinforcement — a person is not born seeking approval or achievement; these needs are shaped by experience. Pain avoidance, however, is a primary drive present from birth: an organism instinctively withdraws from harmful stimuli to protect itself, without any social learning involved. This makes pain avoidance the one motive among the four that is NOT acquired.

• Affiliation: the need to form and maintain social bonds, developed through repeated social interaction — an acquired motive.

• Achievement: the drive to accomplish and excel, shaped by a personal history of success and failure and cultural reinforcement (McClelland's need for achievement) — an acquired motive.

• Approval: the need for others' acceptance, learned through reinforcement of socially desirable behaviour from caregivers and peers — an acquired motive.

• Pain avoidance: an unlearned, biologically wired drive to escape or avoid harmful and damaging stimuli, present without any social conditioning — a primary (unacquired) motive.
