Cognitive and social-emotional development of children in different preschool environments

62 English-speaking preschool children were divided into three groups, a Montessori group (n = 21), a traditional preschool group (n = 21), and a homestaying group (n = 20) to compare their relative cognitive and social-emotional development. Significant differences in favour of the school groups were found for vocabulary, language comprehension, ability to judge the correctness of figural stimuli, visual memory, and perceptual organization. No differences were found for social-emotional development, and no relationship existed between type of preschool and level of development.
