Is language production dynamically regulated by cognitive
control? If so, how domain-general is this process? In two
experiments, we studied conflict adaptation, or conflict-driven
adjustments of control, in two paradigms: Picture-Word
Interference (PWI), which induces linguistic conflict, and
Prime-Probe (PP), which induces visuospatial conflict. Exp. 1
tested within-task conflict adaptation separately in PWI and
PP. Exp. 2 tested cross-task adaptation by alternating the two
tasks in a task-switching paradigm. We found reliable within-
task conflict adaptation in both PWI and PP, but neither an
analysis of individual differences (Exp. 1), nor a direct
manipulation of between-task conflict (Exp. 2) revealed cross-
task adaptation. We further report a robust 2-back within-task
adaptation in Exp. 2 to refute alternative accounts of null cross-
task adaptation. These findings support models of dynamic,
top-down control in language production that posit at least
some degree of domain-specificity.
