Predictability of sinusoidally moving stimuli does not improve the accuracy of the accommodative response

Abstract Previous research work suggests that predictable target motion such as sinusoidal movement can be anticipated by the visual system, thereby improving the accommodative response. The validity of predictable motion for studying human dynamic accommodation is sometimes put into question. The a...
