The general shape of curve for eyes closed is downward 20-40 beats, and rising for the rest of the series; it is less regular, but more accurate than the visual results.
The fact that constant errors are mostly positive leads to a denial of any inhibitory effect of the retarding weight.
For 1 cm. lines,
weight-retarding movements:
For the average of seven subjects we find:
(1) visual control does not improve accuracy or regularity as in free movements;
(2) a retarding weight tends to make errors constant whatever the speed-rate;
(3) the testimony goes to show that the free-movement records are more accurate than the retardation ones.
Mean errors are:
(1) no more accurate and perhaps less regular, when the weight is imposed;
