Abstract:
Broader generalization of earlier findings comparing the relative intelligibility of verbal messages presented aurally and visually was sought by investigation of two additional variables. These were (1) message presentation in distorted from and (2) previous familiarization with the message population. Both of these conditions apply widely in practical operations. Two closely related experiments were conducted to discover (1) the influence of a distracting task on the reception of distorted messages as related to sense channel of presentation, and (2) the effectiveness of message familiarity in combatting the lowered intelligibility of distorted messages, and the possible influence of sense channel in such an effect. The principal findings were the following: (1) introduction of the distracting task significantly reduced the intelligibility of the visually presented messages, while leaving the auditory messages essentially unaffected; (2) previous familiarization significantly increased the intelligibility of the distorted messages as presented through either sense channel; (3) familiarization was significantly more effective when provided through the same sense channel as that through which the distorted form of the message was subsequently presented.
