Naturalistic Object Representations Depend on Distance and Size Cues.

Unlabelled: Egocentric distance and real-world size are important cues for object perception and action. Nevertheless, most studies of human vision rely on two-dimensional pictorial stimuli that convey ambiguous distance and size information. Here, we use fMRI to test whether pictures are represented differently in the human brain from real, tangible objects that convey unambiguous distance and size cues.

Graspability Modulates the Stronger Neural Signature of Motor Preparation for Real Objects vs. Pictures.

The cognitive and neural bases of visual perception are typically studied using pictures rather than real-world stimuli. Unlike pictures, real objects are actionable solids that can be manipulated with the hands. Recent evidence from human brain imaging suggests that neural responses to real objects differ from responses to pictures; however, little is known about the neural mechanisms that drive these differences.

How the brain represents mass.

New fMRI experiments and machine learning are helping to identify how the mass of objects is processed in the brain.
