There are 11 behavioral dimensions which parents and preschool teachers can use in assessing the development of preschool children. These dimensions are: (1) sleeping; (2) eating; (3) toilet habits; (4) range of affect or emotion; (5) variations in play; (6) curiosity; (7) acceptance of authority; (8) initiative; (9) interest; (10) spontaneous affection; and (11) enjoyment of the "good things of life." By observing children over a period of time, adults can use information related to these dimensions to determine whether or not a child is developing normally. (DC)
