The way attention and emotion modulates pain is a complex but relevant topic. Several studies focused on the interaction between the performance of a (non-painful) task and concurrent painful stimuli, which mainly resulted in disruptive performance i.e. reduced accuracy and increased recognition times. The aim of this study was to investigate the interaction between the task complexity nd the stimulus intensity, therefore salience, of phasic nociceptive stimulation.
The main results of this study where:
- Pain ratings can be reduced by increasing the load of attentional resources at the perceptual level of a pain-unrelated task.
- Nevertheless, the disruptive effect of highly intensive nociceptive stimuli on the performance of the perceptual task was only evident under high load. Which is an example of dissociation between the perception induced by the stimulus (i.e. pain) and the attentional effect it produces on the behavior.
Important to note is that (like most studies), For RT (recognition times) analysis, only correct responses were analyzed > from Romero et al.; Pain (2012) article in press. All rights reserved to the Authors.
