title: Nature of kinesthesis as measured through techniques derived from the theory of signal detectability.
abstract: Forearm movement discrimination sensitivity, as measured through techniques derived from the theory of signal detectability, was studied in relationship to forearm movement reproduction sensitivity. As a secondary problem, the two identified measures of kinesthetic sensitivity were also studied in relation to the independent variables of extent of forearm angular movement, direction of movement (supination or pronation), and order that the discrimination and reproduction tests were administered (transfer effect of first test on the second). There was little statistical relationship between kinesthetic discrimination and reproduction sensitivity measures. Both measures of kinesthetic sensitivity were similar in their relationship to the independent variables of extent, direction, and transfer. In both cases, the only significant main effect was that of extent (short movements more accurate than long). Kinesthetic discrimination was observed to be a much more stable measurement of kinesthetic sensitivity than movement reproduction.
