Studies of children's representation of spatial relationships and ability to respond to temporal relationships in photographs are reported. Participants in the study of spatial relationships were 90 children at 5, 8, and 11 years of age, who were asked to reproduce three types of depth relationship: enclosure, occlusion, and perspective. Each child was assigned to either a drawing or a photographic condition. Results revealed that the particular type of spatial relationship had an effect on the children's ability to make accurate reproductions and that this effect varied in the drawing and photographic conditions. Data further indicated that children's representations of spatial relationships are closely tied to the particular media of representation. In the study of temporal relationships in photographs, participants were 96 children at 7 and 11 years of age, who responded to a series of eight photographs depicting a variety of subject matter. Recorded interviews were analyzed for changes in tense, the adverbials "before" and "after," and for any mention of past or future circumstances that could surround the photographs. All subjects made some reference to time during the interviews; however, they were most concerned with discussing the present situation and the appearance of the photos. Statements referring to temporal relationships were grouped in categories concerning actions, events, spatial transformations, or the photographic medium. The finding that types of responses varied among photographs suggests that concerns about time can become part of what is represented in static, atemporal symbols. Findings are interpreted in terms of Werner and Kaplan's (1963) approach to the problem of representation. (RH)
