Concept

Defence mechanisms (such as denial) are unconscious strategies used to manage anxiety. In educational psychology, why a defence mechanism persists is explained not only by intrapsychic factors but also by sociocultural reinforcement: during late adolescence and early adulthood, the peer group becomes a powerful reference group, and any behaviour — including a coping or defence response — that earns peer acceptance tends to be reinforced and sustained, while behaviour that risks peer rejection is avoided.

Application

The stem specifies that the student faces pressure to conform to peer norms, which is a peer-group-level (sociocultural) pressure. Because peer acceptance reinforces whichever coping or defence response keeps the student aligned with the group, the influence of peer acceptance on defence-mechanism selection is the sociocultural factor that keeps the denial in place.

Cross-check

• Institutional rules shaping classroom participation address formal, rule-based classroom behaviour, not the peer-approval dynamic the stem describes.

• Parental academic expectations operate through the family as a reference group — a different social unit from the peers named in the stem.

• Level of personal motivation is an individual, intrapersonal trait rather than a group-level, sociocultural factor.

Only the peer-acceptance factor operates at the sociocultural (peer-group) level the question asks about, confirming it as the answer.
