 T., Reaction, that required for the conduction of a 

 sensor)' impulse to the center, combined with that of 

 the duration of the perception, of the direction of 

 attention (apperception), of the voluntary impulse,

 with their consequent activity. The reaction-time 

 varies according to the part and sense, etc., stimu- 

 lated. Dolley and Cattell found, by experiments 

 upon themselves, that the sensory reactions of electric 

 stimuli were the shortest when the stimulus was 

 applied to the upper arm and the movement made 

 with the hand. They were about j or | second.
