Task-order control in dual-tasks: Only
marginal interactions between conflict at lower levels and higher processes of task
organization
When simultaneously performing two tasks that share response properties,
interference can occur. Besides general performance decrements, performance in the
first task is worse when the second task requires a spatially incompatible response,
known as the backward crosstalk effect (BCE). The size of this BCE, similar to
congruency effects in conflict tasks, is subject to a sequential modulation, with a
smaller BCE after incompatible compared to compatible trials. In the present study,
we focus on a potential bidirectional interaction between crosstalk (and its
resolution) at a lower level of task performance and higher-order processes of task
organization. Two questions were of particular interest: First, do participants
switch task order more frequently after a conflict-prone incompatible trial than
after a compatible trial? Second, does changing task order influence the efficiency
of conflict resolution, as indexed by the size of the sequential modulation of the
BCE. Across four experiments, we only found marginal evidence for an influence of
lower-level conflict on higher-order processes of task organization, with only one
experiment revealing a tendency to repeat task order following conflict. Our results
thus suggest practical independence between conflict and task-order control. When
separating processes of task selection and task performance, the sequential
modulation was generally diminished, suggesting that conflict resolution in
dual-tasks can be disrupted by a deliberate decision about task order, or,
alternatively, by a longer inter-trial interval. Finally, the study found a strong
bias towards repeating the same task order across trials, suggesting that task-order
sets not only impact task performance but also guide task selection.
期刊介绍:
The journal Attention, Perception, & Psychophysics is an official journal of the Psychonomic Society. It spans all areas of research in sensory processes, perception, attention, and psychophysics. Most articles published are reports of experimental work; the journal also presents theoretical, integrative, and evaluative reviews. Commentary on issues of importance to researchers appears in a special section of the journal. Founded in 1966 as Perception & Psychophysics, the journal assumed its present name in 2009.
