What factors contribute to redundant target processing speed besides statistical facilitation? one possibility is that multiple percepts may drive these effects. Another, although not mutually exclusive hypothesis, is that cross- channel cueing from one modality to another may influence response times. We implemented an auditory–visual detection task using the sound- induced flash illusion to examine whether one or both of these possibilities contributes to changes in processing speed; we did so by examining the data of individual participants. our results indicated shorter response times in several participants when multiple flashes were perceived in the standard sound- induced flash illusion, thereby replicating previous work in the literature. Additionally, we found evidence for faster responses in several participants when carrying out the same analysis in trials in which 1 beep was presented with 2 real flashes. overall, our analysis indicates that some observers benefit from cross- modal facilitation, whereas others may benefit from a combination of cross- modal facilitation and increased perceptual judgments.

The specific processes that support comprehension and retention of hypertext information and the manner in which those processes differ from those involved in the comprehension and retention of traditional linear text were examined in 4 experiments. Experiments 1 and 2 demonstrate that although processing hypertext is not more demanding overall than processing linear text, processing hypertext does make more demands for use of relational information. Experiments 3 and 4 provide tests of the operational assumptions and methods used in the initial two experiments and provide converging evidence to support the notion that hypertext requires a different balance of processing resources than does linear text. Results and directions for research with new information technologies are discussed using the constructs of a limited-capacity working memory and material-appropriate processing.
