Nonaphasic and nonfluent, mixed, and anomic aphasic adults participated in a referential communication task in which they described pictures to a nonaphasic listener so that the listener could point to the picture being described from an array of four. Both aphasic and nonaphasic subjects were able to determine what information was crucial for identifying pictures and communicate that information to a listener. The major differences between nonaphasic and aphasic subjects were in efficiency and accuracy of communication. Nonaphasic and nonfluent aphasic subjects were more efficient in communicating information than mixed or anomic aphasic subjects were. Nonfluent aphasic subjects were as efficient as nonaphasic speakers in this respect. Aphasic subjects communicated significantly more inaccurate information than nonaphasic speakers did. However, no more than 5% of the information communicated by aphasic subjects was inaccurate. Finally, aphasic speakers modified their descriptions in response to apparent communication failure in the same way that nonaphasic speakers did.
非失语症、非流畅性失语症、混合性失语症和命名性失语症的成年人参与了一项指称性交流任务，在该任务中，他们向一名非失语症听众描述图片，以便听众能从四张图片的阵列中指出所描述的图片。失语症患者和非失语症患者都能够确定哪些信息对于识别图片至关重要，并将这些信息传达给听众。非失语症患者和失语症患者之间的主要差异在于交流的效率和准确性。非失语症和非流畅性失语症患者在传达信息方面比混合性或命名性失语症患者更有效率。在这方面，非流畅性失语症患者与非失语症患者的效率相当。失语症患者传达的不准确信息比非失语症患者显著更多。然而，失语症患者传达的信息中不准确的不超过5%。最后，失语症患者会像非失语症患者一样，根据明显的交流失败来修改他们的描述。
