Audiovisual Between-Channel Redundancy and Its Effects upon Immediate Recall and Short-Term Memory.
Hsia, H. J.
In an attempt to ascertain the facilitating functions of audiovisual between-channel redundancy in information processing, a series of audiovisual experiments alternating auditory and visual as the dominant and redundant channels were conducted. As predicted, results generally supported the between-channel redundancy when input (stimulus) was beyond the human information processing capacity. Data were also interpreted in terms of various theories such as the lower threshold, summation, energy integration, cumulative strength, cuing, and multiple traces of the audiovisual bisensory presentation, implicitly supporting between-channel redundancy. Evidence obtained from the study was also dismetrically opposite to the hypothesis that short-term memory was essentially an auditory system. Based on findings in neurophysiology, it was argued that both short-term memory and long-term memory might very well be integrated systems. Some conflicting evidence was also found on the position of redundant information of one channel in relation to the other channel. Redundant information coinciding with the dominant channel in the beginning was found significantly better than that at the end with the digit-recall tasks, but not with letter-recall tasks.
