The present study sought to uncover what constraints shape the early development of the perceptual–motor skill of catching, and how intrinsic (i.e., movement possibilities) and extrinsic constraints (i.e., object speed imposes temporal precision) impinge on the perception of whether or not a moving object affords catching. Thirty-five infants (with different preferred catching tendencies) betwe...

It is well known that saturation of ideals is closely related to the “antichain-catching” phenomenon from Foreman-Magidor-Shelah [10]. We consider several antichain-catching properties that are weaker than saturation, and prove: (1) If I is a normal ideal on ω2 which satisfies stationary antichain catching, then there is an inner model with a Woodin cardinal; (2) For any n ∈ ω, it is consistent...

We quantified the accuracy of the perception of the absolute direction of motion-in-depth (MID) of a simulated approaching object using a perceptual task and compared those data with the accuracy of estimating the passing distance measured by means of a simulated catching task. For the simulated catching task, movements of the index finger and thumb of the observer's hand were tracked as partic...

SKILL LEARNING BASED CATCHING MOTION CONTROL Gökçen Çimen M.S. in Computer Engineering Supervisor: Assist. Prof. Dr. Tolga Kurtuluş Çapın July, 2014 In real world, it is crucial to learn biomechanical strategies that prepare the body in kinematics and kinetics terms during the interception tasks, such as kicking, throwing and catching. Based on this, we presents a real-time physics-based approa...

In ball sports, it is usually acknowledged that expert athletes track the ball more accurately than novices. However, there is also evidence that keeping the eyes on the ball is not always necessary for interception. Here we aimed at gaining new insights on the extent to which ocular pursuit performance is related to catching performance. To this end, we analyzed eye and head movements of nine ...
