Neuromotor Noise, Error Tolerance and Velocity-Dependent Costs in Skilled Performance
In motor tasks with redundancy neuromotor noise can lead to variations in execution while achieving relative invariance in the result. The present study examined whether humans find solutions that are tolerant to intrinsic noise. Using a throwing task in a virtual set-up where an infinite set of angle and velocity combinations at ball release yield throwing accuracy, our computational approach ...
متن کاملPerformance analysis of algorithmic noise-tolerance techniques
In this paper, we present performance analysis of algorithmic noisetolerance (ANT) techniques. First, we analyze the predictor and 'RPR based ANT schemes. Next, we present a hybrid ANT scheme :which is resilient to burst errors usually occurring in a high softerror rate (Per) region. For a frequency selective FIR Pltering, it is shown that simulation results match well with the analytic bounds ...
متن کاملStreaks in skilled performance.
Experiments in golf putting and darts demonstrated that skilled performance is streaky. The tendency for outcome sequences to form streaks was greatest when the task difficulty was such that about half the trials were successful. Mixtures of the two activities were also streaky, even when periodic interruption made the individual components resemble a random Bernoulli process. Formal models of ...
متن کاملSlow motor performance in girls with Turner Syndrome is not related to increased neuromotor noise.
This study examined the relationship between decreased speed-accuracy trade-off and increased neuromotor noise in girls with Turner Syndrome (TS). Fifteen girls with TS and 15 age-matched controls performed isometric force contractions with both index fingers separately at 5 force levels, based on their maximum voluntary contraction. The results revealed that (a) groups did not differ in speed-...
متن کاملNeuromotor noise limits motor performance, but not motor adaptation, in children.
Children do not typically appear to move with the same skill and dexterity as adults, although they can still improve their motor performance in specific tasks with practice. One possible explanation is that their motor performance is limited by an inherently higher level of movement variability, but that their motor adaptive ability is robust to this variability. To test this hypothesis, we ex...
