Temporal coherency of mechanical stimuli modulates tactile form perception

Spatio-temporal prediction modulates the perception of self-produced stimuli.

We investigated why self-produced tactile stimulation is perceived as less intense than the same stimulus produced externally. A tactile stimulus on the palm of the right hand was either externally produced, by a robot or self-produced by the subject. In the conditions in which the tactile stimulus was self-produced, subjects moved the arm of a robot with their left hand to produce the tactile ...

Temporal recalibration to tactile-visual asynchronous stimuli.

Here we demonstrate that the perceptual system adapts to tactile-visual temporal asynchronies (i.e., temporal recalibration). Participants were exposed to a train of tactile and visual stimuli with a constant time lag (either -100ms, 0ms, or 100ms; with negative values indicating that the tactile stimulus came first). Following exposure, they were presented tactile-visual test stimulus pairs an...

Hearing Shapes Our Perception of Time: Temporal Discrimination of Tactile Stimuli in Deaf People

Confronted with the loss of one type of sensory input, we compensate using information conveyed by other senses. However, losing one type of sensory information at specific developmental times may lead to deficits across all sensory modalities. We addressed the effect of auditory deprivation on the development of tactile abilities, taking into account changes occurring at the behavioral and cor...

Threat modulates perception of looming visual stimuli

Among the most critical of visual functions is the detection of potentially hazardous or threatening aspects of the environment. For example, objects on a collision course with an observer must be quickly identified to allow sufficient time to prepare appropriate defensive or avoidant responses. Directly approaching objects produce a specific accelerating pattern of optical expansion, known as ...
