Distinct brain responses to different inhibitions: Evidence from a modified Flanker Task

Applying the Flanker Task to Political Psychology: A Research Note

One of the two stated objectives of the new “Research Note” section of Political Psychology is to present short reports that highlight novel methodological approaches. Toward that end, we call readers’ attention to the “flanker task,” a research protocol widely employed in the study of the cognitive processes involved with detection, recognition, and distraction. The flanker task has increasing...

Proactive versus reactive task-set inhibition: evidence from flanker compatibility effects.

Two converging tests were used to determine whether people proactively inhibit recently performed tasks when switching to new tasks. A task-cuing paradigm was used. In each trial, the relevant stimulus was accompanied by flankers belonging either to the task performed on the immediately preceding trial (lag 1) or a more distant trial (lag 2 +). If the just-performed task is inhibited when switc...

The flanker effect does not reflect the processing of "task-irrelevant" stimuli: evidence from inattentional blindness.

It is often the case that stimuli (or aspects of a stimulus) are referred to as being "task-irrelevant." Here, we recount where this label originated and argue that the use of this label is at odds with the concept of "relevance" that has arisen in the contingent-capture literature. This is not merely a matter of labels, but a matter of inference: When people describe a flanker stimulus as bein...

Repetition priming influences distinct brain systems: evidence from task-evoked data and resting-state correlations.

Behavioral dissociations suggest that a single experience can separately influence multiple processing components. Here we used a repetition priming functional magnetic resonance imaging paradigm that directly contrasted the effects of stimulus and decision changes to identify the underlying brain systems. Direct repetition of stimulus features caused marked reductions in posterior regions of t...
