Hierarchical control of cognitive processes was studied by examining the relationship
between sequence-and task-level processing in the performance of explicit, memorized task …

A series of 7 experiments used dual-task methodology to investigate the role of working
memory in the operation of a simple action-control plan or program involving regular …

The procedural frame hypothesis, derived from a theoretical analysis of cognitive control
(Carlson 1997), suggests that instantiated goals correspond to intentions to apply operators …

A model of cognitive control in task switching is developed in which controlled performance
depends on the system maintaining access to a code in episodic memory representing the …

To find evidence for hierarchically controlled execution of movement sequences, 5 35–45 yr
old right-handed women were required to perform memorized sequences of finger …

Four experiments explored the task span procedure: Subjects received lists of 1-10 task
names to remember and then lists of 1-10 stimuli on which to perform the tasks. Task span is …

This study examined how task switching is affected by hierarchical task organization.
Traditional task-switching studies, which use a constant temporal and spatial distance …

It is well known that movement sequences are initiated and executed more slowly as they
become longer. Those effects of sequence length, which have been found to lessen with …

Recent evidence suggests substantial response-time costs associated with lag-2 repetitions
of tasks within explicitly controlled task sequences [Koch, I., Philipp, AM, Gade, M.(2006) …

Four experiments examined automatic and intentional activation of task sets in a switching
paradigm. Experiment 1 demonstrated incidental task sequence learning that was not …
