Distance errors: pointing to the range effect

Article Abstract:

Flanders et al is commended for their ingenious and novel approach to the problem of coordinate transformations in motor control, however, exception is taken on the formulation of the proposed model's experimental methods, results and data interpretation. It is suggested that a blocked presentation of targets would have greatly reduced range effects. Also, errors of interpretation give rise to Flanders' statements on shoulder- versus head-centered representations of target parameters.

Now you see it, now you don't: how delaying an action system can transform a theory

Article Abstract:

The research conducted by Martha flanders et al showed that the pattern of error in terminal position may reflect the nature not only of sensorimotor transformation but of perceptual-memory/motor transformations. However, it was proposed that the research's description of transformations has no relevance on the nature of the normal sensory-motor transformations when reaching out for real objects.
