On-line versus off-line control of rapid aiming movements.

摘要: Abstract Recent studies have shown the importance of visual feedback during rapid initial phase aiming movements for control direction (e.g., Bard, Paillard, Fleury, Hay, & Larue, 1990; Blouin, Teasdale, in press; 1991). In most these studies, conditions were presented blocked sessions. Consequently, higher-order processes feedforward and/or learning processes), along with on-line processing feedback, might contributed to better accuracy found when subjects had only portion (compared without feedback). To test this possibility, we studied subjects' performance arm under different types presentation (random, precued, and blocked) trajectory (no vision, only, vision entire trajectory). Directional errors larger no-vision conditi...
