Two studies were conducted to analyze script and event structures of preschool children's dialogues during play. To identify scripts in discourse data, the following procedural guidelines were developed and followed: (1) identify exchanges of continuous discourse, (2) delineate all conversational episodes, (3) select all episodes with pretend play themes, (4) extract play events from play episodes, and (5) extract play scripts from interrelated play events. In one study, three dyads (all 4-year-olds) were observed in three different play contexts. Longest and shortest segments of continuous discourse in each dyad were reported for playdough, sandbox, and telephone play. Findings indicated 4-year-old friends used scripts across play contexts to topicalize their longest discourse segments. In a second study, 10 dyads composed of children between 3 and 5 years of age were audiotaped during play with a large sand-filled tub containing various implements. Findings pertained to the role of scripts in structuring all pretend play conversations of each pair. Generally, results revealed that, when engaged in scripted pretense, subjects consistently were able to maintain discourse at or beyond four exchanges and that they shared many play events in their talk.
