Cardiac deceleration and accuracy of performance: recalculation of standard score transform.
In two previous studies the standard score transform used was based on a standard deviation derived from the mean standard deviations of the raw data in the six classifications employed in the studies rather than on one based on the entire set of raw scores as is the more common practice. The data were reanalyzed using the latter basis and major findings were confirmed. Some of the minor findings, however, were changed. These changes are pointed out and discussed where they occurred.
