Attentional control and the competition between nonpain goals and the threat of pain

Abstract

Background

Fully understanding attention to pain requires taking into account the motivational context. Both pain- and (nonpain) goal-related information attracts attention. An intriguing question is which attentional bias prevails when pain- and goal-related information co-occurs? Reduced attentional bias towards pain- and goal-related information was predicted when the other competing information was presented simultaneously. Moreover, trait attentional control was predicted to be associated with stronger attentional bias towards goal-related information particularly in the presence of pain-related information.

Methods

Attentional competition between pain- and (nonpain) goal-related information was measured in ninety participants using a dot-probe task presenting two stimuli (pain-related, goal-related or neutral) simultaneously. Reaction time was the dependent variable. Dot-probe trials alternated with goal trials to induce a temporary goal. Trait attentional control was measured with the attentional control scale.

Results

For pain-related neutral stimulus pairs, participants responded fastest when probes appeared on the same, compared to the opposite, location as the pain-related stimulus. For pain-goal-related stimulus pairs, responses were fastest when probes appeared on the same, compared to the opposite, location as the goal-related stimulus. Higher trait attentional control was associated with faster responding when probes appeared on the same, compared to the opposite, location as the goal-related stimulus. Unpredicted, this effect was irrespective of the co-occurring stimulus (neutral vs. pain-related).

Conclusions

The findings suggest that the unintentional allocation of attention towards events related to a temporary (nonpain) goal prevails over attentional bias to events predicting pain. Trait attentional control predicts stronger attentional allocation towards events related to a temporary goal.

Significance

These findings indicate that treatment interventions facilitating goal pursuit in patients with chronic pain are beneficial in reducing attentional biases towards pain-related events.
