The problem of serial order in behavior: Lashley’s legacy by Rosenbaum, David A., Cohen, Rajal G., Jax, Steven A., Weiss, Daniel J., van der Wel, Robrecht

“…In a prescient paper Karl Lashley (1951) rejected reflex chaining accounts of the sequencing of behavior and argued instead for a more cognitive account in…”

The mirror illusion's effects on body state estimation by Soliman, Tamer M., Buxbaum, Laurel J., Jax, Steven A.

“…The mirror illusion uses a standard mirror to create a compelling illusion in which movements of one limb seem to be made by the other hidden limb. In this…”

Two-component models of reaching: Evidence from deafferentation in a Fitts’ law task by Medina, Jared, Jax, Steven A., Coslett, H. Branch

“…Both feedforward and feedback mechanisms are used to ensure accurate movements. Feedback information comes primarily from vision and proprioception; the…”

Contributions of efference copy to limb localization: Evidence from deafferentation by Medina, Jared, Jax, Steven A, Brown, Mark J, Coslett, H. Branch

“…Abstract Previous research with deafferented subjects suggests that efference copy can be used to update limb position. However, the contributions of efference…”

Extending Fitts' Law to three-dimensional obstacle-avoidance movements: support for the posture-based motion planning model by Vaughan, Jonathan, Barany, Deborah A, Sali, Anthony W, Jax, Steven A, Rosenbaum, David A

“…According to Fitts' Law, the time (MT) to move to a target is a linear function of the logarithm of the ratio between the target's distance and width. Although…”

Response interference between functional and structural actions linked to the same familiar object by Jax, Steven A., Buxbaum, Laurel J.

“…Viewing objects with the intention to act upon them may activate task-irrelevant motor responses. Many manufactured objects are associated with two action…”

More than (where the target) meets the eyes: Disrupted visuomotor transformations in optic ataxia by Jax, Steven A., Buxbaum, Laurel J., Lie, Eunhui, Coslett, H. Branch

“…Visually guided reaching entails multiple coordinate frame transformations between retina-centered target location and body-centered limb location. Reaching…”

Impairments in action and perception after right intraparietal damage by Medina, Jared, Jax, Steven A., Coslett, H. Branch

“…We examined visually-guided reaching and perception in an individual who underwent resection of a small tumor in right intraparietal sulcus (pIPS). In the…”

Movement Imitation via an Abstract Trajectory Representation in Dorsal Premotor Cortex by Wong, Aaron L, Jax, Steven A, Smith, Louisa L, Buxbaum, Laurel J, Krakauer, John W

“…Humans are particularly good at copying novel and meaningless gestures. The mechanistic and anatomical basis for this specialized imitation ability remains…”

Hand Path Priming in Manual Obstacle Avoidance: Evidence that the Dorsal Stream Does Not Only Control Visually Guided Actions in Real Time by Jax, Steven A, Rosenbaum, David A

“…According to a prominent theory of human perception and performance (M. A. Goodale & A. D. Milner, 1992), the dorsal, action-related stream only controls…”

Hand path priming in manual obstacle avoidance: Rapid decay of dorsal stream information by Jax, Steven A., Rosenbaum, David A.

“…The dorsal, action-related, visual stream has been thought to have little or no memory. This hypothesis has seemed credible because functions related to the…”
