Perceived Cue Validity Alters the Effectiveness of Visuo-Haptic Integration Particularly at Subliminal Levels

Using monofilament hairs that were presented either unimodally, or bimodally with conicidentally presented visual cues of varying validities, we psychophysically assessed the hierarchical efficiency of visuo-haptic integration across a range of tactile intensities. Our findings reveal an important interdependency between attentional awareness (as defined by cue predictability) and stimulus saliency.
