Now You See It, Now You Don’t: Verbal But Not Visual Cues Facilitate Visual Object Detection
Does knowing what one is about to see make it easier to see it? The answer may depend on the source of the knowledge. Participants completed an object detection task in which they made an object-presence or -absence decision to brieflypresented letters. Hearing the letter name prior to the detection task facilitated detection (d’), but seeing a preview of the to-be-detected stimulus did not. Fo...
متن کاملObject Category Detection Using Audio-Visual Cues
Categorization is one of the fundamental building blocks of cognitive systems. Object categorization has traditionally been addressed in the vision domain, even though cognitive agents are intrinsically multimodal. Indeed, biological systems combine several modalities in order to achieve robust categorization. In this paper we propose a multimodal approach to object category detection, using au...
متن کاملVisual rhythm perception improves through auditory but not visual training
Figure 1. Experimental procedures and results of visual rhythm discrimination training. (A) Schematic of a visual trial from the rhythm discrimination task. In this example, the patterns of the rhythm sequences are different. (B) Depiction of the experimental design. Sessions were completed 24 to 48 hours apart. For all groups, the preand post-test trials contained visual stimuli only. (C) Mean...
متن کاملMaking the Invisible Visible: Verbal but Not Visual Cues Enhance Visual Detection
BACKGROUND Can hearing a word change what one sees? Although visual sensitivity is known to be enhanced by attending to the location of the target, perceptual enhancements of following cues to the identity of an object have been difficult to find. Here, we show that perceptual sensitivity is enhanced by verbal, but not visual cues. METHODOLOGY/PRINCIPAL FINDINGS Participants completed an obje...
متن کاملInfluence of Correlated Visual Cues on Auditory Signal Detection
Two experiments investigated the effects on aUditory signal detection of introducing visual cues that were partially correlated with the signal events. The results were analyzed in terms of a detection model that assumes that such cue-signal correlations will not affect sensitivity, but will instead cause the subject to develop separate response biases for each cue. The model specifies a functi...
