  1. Grasping of Real-World Objects Is Not Biased by Ensemble Perception.Annabel Wing-Yan Fan, Lin Lawrence Guo, Adam Frost, Robert L. Whitwell, Matthias Niemeier & Jonathan S. Cant - 2021 - Frontiers in Psychology 12.
    The visual system is known to extract summary representations of visually similar objects which bias the perception of individual objects toward the ensemble average. Although vision plays a large role in guiding action, less is known about whether ensemble representation is informative for action. Motor behavior is tuned to the veridical dimensions of objects and generally considered resistant to perceptual biases. However, when the relevant grasp dimension is not available or is unconstrained, ensemble perception may be informative to behavior by (...)

  • The Role of Haptic Expectations in Reaching to Grasp: From Pantomime to Natural Grasps and Back Again.Robert L. Whitwell, Nathan J. Katz, Melvyn A. Goodale & James T. Enns - 2020 - Frontiers in Psychology 11.
    When we reach to pick up an object, our actions are effortlessly informed by the object’s spatial information, the position of our limbs, stored knowledge of the object’s material properties, and what we want to do with the object. A substantial body of evidence suggests that grasps are under the control of “automatic, unconscious” sensorimotor modules housed in the “dorsal stream” of the posterior parietal cortex. Visual online feedback has a strong effect on the hand’s in-flight grasp aperture. Previous work (...)
