Visual fixations during processing of time-compressed audiovisual presentations.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Time-compression is a technique that allows users to adjust the playback speed of audio recordings, but comprehension declines at higher speeds. Previous research has shown that under challenging auditory conditions people have a greater tendency to fixate regions closer to a speaker's mouth. In the current study, we investigated whether there is a similar tendency to fixate the mouth region for time-compressed stimuli. Participants were presented with a brief audiovisual lecture at different speeds, while eye fixations were recorded, and comprehension was tested. Results showed that the 50% compressed lecture group looked more at the nose compared to eye fixations for the normal lecture, and those in the 75% compressed group looked more towards the mouth. Greater compression decreased comprehension, but audiovisual information did not reduce this deficit. These results indicate that people seek out audiovisual information to overcome time-compression, demonstrating the flexibility of the multimodal attentional system.
