Abstract:
|
A large portion of our everyday lives is spent engaged in mind wandering, or task-unrelated thoughts. While mind wandering has some benefits to creativity, it is also a major concern for safety critical tasks such as driving, in which external distraction has already been shown to have a negative impact. The goal of this paper was to identify the impact of mind wandering on two specific mechanisms of attention; target facilitation and distractor suppression. Participants were shown a series of trials in which rare targets either displayed lower salience features or shared a feature with distractors. Participants were asked periodically to report their thought content (task-related or task-unrelated), and this was used to pair their performance with thought-type. Generalized linear mixed-effects models were used to analyze the data. The findings were a significant reduction of target facilitation and increase in distractor suppression while mind wandering. These findings suggest while mind wandering individuals are not suppressing all external information, but rather selectively attenuating processing based on task-relevance of stimuli.
