Donders' law in torticollis.
We investigated head movements of patients with spasmodic torticollis toward targets in various directions. These patients, whose severe dystonia was reflected in an abnormal resting head position, appeared to retain a Donders'-type strategy for the control of the rotational degrees of freedom of the head. As in normals, rotation vectors, representing head orientation, were confined to a curved...

متن کاملAnomalies of Refraction, Donders' Essay
Apart from the interest of the book on historical grounds, its value is enhanced by the fact that it is a summary of the late Professor Donders' monumental work on the subject in which he was the pioneer. The anomalies of refraction are summarized in a series of aphorisms which show, in a striking manner, how far the writer was in advance of his times, and how little has since been added to the...
متن کاملVerification of Donders' subtraction method.
In an experiment on 6 young adults advance (precued) information of the correct choice response was utilized completely: (a) For precue-to-stimulus intervals (PSIs) clearly shorter than the difference between mean choice and simple reaction time (RT), median response latency (L) measured from precue onset was invariant; (b) For clearly longer PSIs, median RT was very near the value for simple R...
