Visual Perception And Action In Reaching During Upper Limb Obstacle Avoidance, Nondon Chakraborty
Visual Perception And Action In Reaching During Upper Limb Obstacle Avoidance, Nondon Chakraborty
Theses and Dissertations (Comprehensive)
During everyday activities, people reach to specific objects with their hands and avoid obstacles. For people to move successfully through an obstacle gap, it is necessary to be able to accurately perceive the actions that the surroundings afford and adjust hand movements accordingly. Reaching behaviours, including planning (perception) and execution (action), depend on visual information. This study aimed to understand and detect the differences between perceptual judgment and actual performance of both hands during a reaching task at the time of obstacle avoidance by using a hand-scaled approach. Participants were young adults (male (n=7) and female (n=10) aged 18 to …
Investigating The Inhibition Of The Return Of Attention In The Tactile Domain, Robert Plax
Investigating The Inhibition Of The Return Of Attention In The Tactile Domain, Robert Plax
Theses and Dissertations (Comprehensive)
Purpose: The time-course needed to elicit tactile inhibition of return (IOR) has not been well-defined due to the paucity of research in this area especially studies investigating spatial discrimination. Reportedly tactile IOR uses higher-order mental representations to orient attention spatially yet the properties of low-level dermatomal maps may better account for how IOR orients tactile attention in space although its contribution is unclear. The present study sought to establish a time-course that evokes IOR in a unimodal tactile spatial discrimination task and decouples the contribution of the dermatome from higher-order representations. Methods: Two conditions containing distinct tactile cue-target paradigms designed …
