How is Attention Deployed During Goal Directed Movements? Other events...
People make goal directed movements to interact with their environment. We examined how attention is deployed during goal directed movements and how shifts in attention impact these movements. In the first study, we used a dual task paradigm to investigate how attention can be divided between a search task and a pointing task. Results suggest that shared attentional resources between two tasks degrades performance on both tasks. Movement latency, but not movement time, was also affected by dual task conditions. In a second study, we mapped the spatiotemporal profile of attention relative to a reach. Results showed a consistent pattern of facilitation in the planning stages of the reach, with attention increasing and then reaching a plateau during the completion of the movement before dropping off. Altogether, the results suggest that attention can be deployed dynamically during a goal directed movement and affect the outcome of the movement.
