Evidence for interaction between the stop signal and the Stroop task conflict.

Abstract

Performance of the Stroop task reflects two conflicts--informational (between the incongruent word and ink color) and task (between relevant color naming and irrelevant word reading). The task conflict is usually not visible, and is only seen when task control is damaged. Using the stop-signal paradigm, a few studies demonstrated longer stop-signal reaction times for incongruent trials than for congruent trials. This indicates interaction between stopping and the informational conflict. Here we suggest that "zooming in" on task-control failure trials will reveal another interaction--between stopping and task conflict. To examine this suggestion, we combined stop-signal and Stroop tasks in the same experiment. When participants' control failed and erroneous responses to a stop signal occurred, a reverse facilitation emerged in the Stroop task (Experiment 1) and this was eliminated using methods that manipulated the emergence of the reverse facilitation (Experiment 2). Results from both experiments were replicated when all stimuli were used in the same task (Experiment 3). In erroneous response trials, only the task conflict increased, not the informational conflict. These results indicate that task conflict and stop-signal inhibition share a common control mechanism that is dissociable from the control mechanism activated by the informational conflict.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The task's well-documented interference effects occur when the color word is printed in a color different than the word's meaning, requiring inhibitory control processes to stop automatic word reading while prioritizing less automatic color recognition.

    “The task’s well-documented interference effects occur when the color word is printed in a color different than the word’s meaning (e.g., the word ‘red’ printed in blue font), requiring inhibitory control processes to stop the automatic word reading while prioritizing the less automatic color recognition (98).”
  • The task's inhibition demands occur because of the overlearned, automatic tendency to read words, combined with task instructions to ignore the word's meaning and instead respond based on the word's font color.

    “The task’s inhibition demands occur because of the overlearned, automatic tendency to read words, combined with task instructions to ignore the word’s meaning and instead respond based on the word’s font color.”
  • Experimental evidence indicates that both stroop and stop-signal task types share a common inhibitory control mechanism, and factor analytic evidence indicates that both tasks load together.

    “This conclusion appears unlikely, however, based on experimental evidence indicating that both task types share a common inhibitory control mechanism (98, 114) and factor analytic evidence indicating that both tasks load together (e.g., 5, 17).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
