This report is the second in a series of investigations designed to develop a working model identifying the effects of trade-offs between selected conversational maxims on public attitudes toward augmentative and alternative communication (AAC) system users and their communication. In the current study, trade-offs between the informativeness of a prestored message and its speed of delivery were examined. A total of 96 salesclerks participated. Sixteen scripted, video-taped conversational conditions, involving an AAC customer and a clerk at a checkout counter,, were used to manipulate message informativeness and speed of message delivery. Following each assigned viewing, participants completed a questionnaire designed to assess their attitudes toward the AAC user and his or her communication. The conditions involving (a) the quickly delivered message with excessive information, (b) the slowly delivered message with adequate information preceded by a floorholder, and (c) the slowly delivered message with adequate information without a floorholder were rated higher than (d) the quickly delivered message with inadequate information. There was no main effect for participant or AAC user gender. Implications regarding a model of conversational trade-offs. and technological applications are discussed.
