abstract="Heart rate variability often decreases with increased cognitive load (Kalsbeek, 1971). Studies (Manenica, 1977) varying task pacing requirements unexpectedly revealed decreased SA in self-pacing (self-controlled intra-task event timing) compared to external-pacing (experimenter- or apparatus-controlled event timing). But why should self-pacing ever involve higher cognitive load? Since Ss must time events and otherwise monitor and structure their own performance in self- but not external-pacing, perhaps these responsibilities lead to higher cognitive load in self-pacing when work-rates are equated between self-and externally-paced conditions.Two experiments were conducted to examine possible sources of cognitive load in self-pacing. In Experiment II, an attempt was made to reduce cognitive load by providing new sources of extrinsic feedback on a visual display. In both studies physical work load was held constant across experimental conditions.<p /><p>Language: en</p>",
