BACKGROUND The purpose of this study was to assess participants' ability to perform tasks requiring attention, short term memory, and simple motor skill while sitting, standing or walking at an active workstation. METHODS Fifty participants completed the Stroop Color Word test (SCWT), Auditory Consonant Trigram test (ACTT), and Digital Finger Tapping test(More)
BACKGROUND The effect of active workstation implementation on speech quality in a typical work setting remains unclear. PURPOSE To assess differences between sitting, standing, and walking on energy expenditure and speech quality. METHODS Twenty-two females and 9 males read silently, read aloud, and spoke spontaneously during 3 postural conditions:(More)
The psychophysical methods of the theory of signal detectability were applied to the measurement of kinesthetic recognition sensitivity. Subjects (n = 12) were tested on a kinesthetic discrimination apparatus, and were randomly assigned to one of four treatment conditions. Each subject operated under five response criteria which were imposed through a(More)
In this paper, we propose novel techniques for feature parameter extraction based on MFCC and feature recognition using dynamic time warping algorithm for application in speaker-independent isolated digits recognition. Using the proposed Weighted MFCC (WMFCC), we achieve low computational overhead for the feature recognition stage since we use only 13(More)
Subjects for this research were 153 prospective pilots who were tested on computerized versions of the Two Hand Coordination (2HC) and Complex Coordination (CC) psychomotor tests. Independent variables included five basic error scores associated with the two psychomotor tests. The criterion for pilot performance was conceptualized as a function of the(More)
Subjects for this research were 320 prospective pilots who were tested on computerized versions of the Two Hand Coordination (2HC) and Complex Coordination (CC) psychomotor tests. Independent variables included five basic error measures associated with the two tests, as well as seven new variables that had not previously been utilized. Results of MANOVA and(More)
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(More)
