This study attempted to discover the characteristics of the developmental process whereby children follow a sequential pattern in their understanding of social relationships. A questionnaire was administered describing several simple dyadic situations in terms of one person helping or hurting another. The respondents were to indicate whether the second actor was likely to help, hurt, or show avoidance in response. To point out changes in conceptions, a comparison of collaborative and disengaging responses for each sex and age group was made. There were few evidences of significant changes with age, attributed in part to the extreme simplicity of the questionnaire. There is also the possibility that basic forms of interpersonal perception are not so susceptible to orderly patterns of change (NG)
