Based on previous research demonstrating that a conversation MOP (memory organization packet) exists that organizes scenes (topics) in conversations, this research explores the generalizability of the MOP when faced with differing situational demands. This research tests a normative sequential progression claim of the MOP perspective by examining the degree to which the MOP permits routine progression in topical talk in initial interactions as acquaintance goals vary. As predicted, dyads having similar acquaintanceship goals were found to exhibit similar conversational structures; the conversational structures for dyads having differing acquaintanceship goals were also found to be similar; and the progression of dyads through conversations in terms of transitions between topics also exhibited structural invariance. It was therefore concluded that (a) certain topics of talk occur almost regardless of acquaintanceship desires despite idiosyncratic additions, (b) multiple topics of talk are appropriate at any given point but what is appropriate at one point is not appropriate at other points, and (c) conversational sequencing follows a normative progression. In other words, conversational behavior is both routine and adaptive, although the adaptation is in itself routine.
