Final answer:
The main difference lies in reactivity and self-regulation, with inhibited individuals being shy and reserved due to higher reactivity, whereas uninhibited individuals are outgoing and spontaneous with lower reactivity.
Step-by-step explanation:
The difference between an inhibited temperament and an uninhibited temperament can be understood in terms of reactivity and self-regulation, important dimensions of our adult personality. An inhibited temperament typically refers to individuals who are shy and reserved, characterized by a higher reactivity to new or challenging stimuli and a stronger regulation in controlling that response to avoid unfamiliar situations. On the other hand, an uninhibited temperament describes individuals who are outgoing and spontaneous, showing lower reactivity to new stimuli and less regulation, readily engaging with novel situations and people.
