Cultures in which the community is closed and based on agriculture (Kenya, India, etc.) experience lower social engagement than those in more open communities (United States, Okinawa, etc.) where interactions with peers is encouraged. Children in Mayan, Indian, Mexican, and Kenyan cultures are less expressive in social styles during interactions and they spend little time engaged in socio-dramatic activities. They are also less assertive in social situations. Self-expression and assertiveness in social interactions are related to shyness and inhibition in that when one is shy or inhibited one exhibits little or no expressive tendencies. Assertiveness is demonstrated in the same way, being shy and inhibited lessen one's chances of being assertive because of a lack of confidence.
