Colors and Handles: How Action Primes Perception / M. Costantini, D. Quarona, C. Sinigaglia. - In: FRONTIERS IN HUMAN NEUROSCIENCE. - ISSN 1662-5161. - 15(2021), pp. 628001.1-628001.6. [10.3389/fnhum.2021.628001]
Abstract:
How deeply does action influence perception? Does action performance affect the perception of object features directly related to action only? Or does it concern also object features such as colors, which are not held to directly afford action? The present study aimed at answering these questions. We asked participants to repeatedly grasp a handled mug hidden from their view before judging whether a visually presented mug was blue rather than cyan. The motor training impacted on their perceptual judgments, by speeding participants’ responses, when the handle of the presented mug was spatially aligned with the trained hand. The priming effect did not occur when participants were trained to merely touch the mug with their hand closed in a fist. This indicates that action performance may shape the perceptual judgment on object features, even when these features are colors and do not afford any action. How we act on surrounding objects is therefore not without consequence for how we experience them.
