The Performance of Albino Mice in the Maze Situation with Stimulation of the Vestibular Sense as Motivation and its Relative Absence as Reinforcement

Changes in choices of preferred playmates by 3- and 4-year-old children were observed over the course of a school year. All of the children in this study participated in planned, fully mainstreamed, same-age preschool classes. Sociometric assessments were obtained from all children without disabilities in October, February, and May of the school year; peer nominations of three “best friends” were obtained at the beginning and end of the school year. The 3-year-old children showed a general decline in the ratings given to all of their peers over the course of the school year. Four-year-old children showed significant preferences for same-sex peers without disabilities as playmates. The implications of these findings for integrated programs are discussed.
