Determining the location of effects and their validity for obstacle avoidance tasks

摘要: Reach-to-grasp movements, in combination with obstacle avoidance, have been the subject of many studies. However, as no widely acknowledged standards yet developed concerning conduction experiments and analysis results, researchers this field often to make their own choices when studying these movements. As an example this, data is analyzed assumption homogeneous variances between conditions. Therefore, it was scope study determine validity that assumption, by determining intervals during which effect found while performing avoidance task testing for heterogeneous variances. This done kinematic parameters lateral deviation, aperture velocity. In case were within interval a significant effect. velocity, effects conditions found. Namely though, differences still found, implying both interference caused some conditions, well need test variance if other experimental setting are be conclusion, condition can not made arbitrarily.
