The temporal tuning hypothesis suggests that individuals adjust the timing of cognitive performances to achieve temporal coordination of mental processes and the data on which they operate, and that this adjustment becomes more precise with practice. Participants in two experiments performed self-paced multiple-step arithmetic tasks in which the information(More)
Intentions can be represented theoretically as active, structured states of working memory. This approach is complementary to standard componential and capacity approaches to understanding executive control. We report the results of several studies examining hypotheses derived from this view of intentions. Carlson (1997, 2002) described intentions as mental(More)
We argue that conscious intentions are central to the cognitive control of activity, in contrast to the view that the experience of conscious control is an illusion (Wegner & Wheatley, 1999). We suggest that instantiating a goal to form a conscious intention serves the information-processing function of establishing a procedural frame of reference that(More)
Physiological stimuli which increase postural extensor tone also increase excitability of the crossed extension reflex (CER). We report here that such stimuli increase excitability of the CER recorded from rectus femoris (RF) more than that of vastus medialis (VM). The difference might reflect an important role of the biarticular actions of RF, which is(More)
