Stability of magnitude-production scales for lingual vibrotactile sensation.
The stability of lingual vibrotactile magnitude scales produced by the method of magnitude production was investigated for 10 adult subjects. These subjects produced highly stable magnitude scales across two test sessions separated by 1 wk. The subjects appeared to use absolute rather than ratio scales in the magnitude-production task. A discussion of the stability of the scales is conducted with reference to the likelihood of an internal, absolute mechanism for magnitude scaling.
