Arnold, Derek H.; Wegener, Signy V.; Brown, Francesca; Mattingley, Jason B. – Journal of Experimental Psychology: Human Perception and Performance, 2012
Grapheme-color synesthesia is an atypical condition in which individuals experience sensations of color when reading printed graphemes such as letters and digits. For some grapheme-color synesthetes, seeing a printed grapheme triggers a sensation of color, but "hearing" the name of a grapheme does not. This dissociation allowed us to…

Hartcher-O'Brien, Jessica; Alais, David – Journal of Experimental Psychology: Human Perception and Performance, 2011
This study examines how audiovisual signals are combined in time for a temporal analogue of the ventriloquist effect in a purely temporal context, that is, no spatial grounding of signals or other spatial facilitation. Observers were presented with two successive intervals, each defined by a 1250-ms tone, and indicated in which interval a brief…

Liu, Charles C.; Wolfgang, Bradley J.; Smith, Philip L. – Journal of Experimental Psychology: Human Perception and Performance, 2009
Recent spatial cuing studies have shown that detection sensitivity can be increased by the allocation of attention. This increase has been attributed to one of two mechanisms: signal enhancement or uncertainty reduction. Signal enhancement is an increase in the signal-to-noise ratio at the cued location; uncertainty reduction is a reduction in the…
