The interruptive effect of pain on attention

Cognitive load selectively influences the interruptive effect of pain on attention. – PubMed – NCBI – July 2017

Pain is known to interrupt attentional performance. Such interference effects seem to occur preferentially for tasks that are complex and/or difficult.

However, few studies have directly manipulated memory load in the context of pain interference to test this view.

Therefore, the present study examines the effect of experimental manipulations of both memory load and pain on three tasks previously found to be sensitive to pain interference.  

Three experiments were conducted.  

A different task was examined in each experiment, each comprising of a high and low cognitive load versions of the task.

  1. Experiment 1 comprised of an attention span (n-back) task,
  2. Experiment 2 an attention switching task, and
  3. Experiment 3 a divided attention task.

Each task was conducted under painful and non-painful conditions.

Within the pain condition, an experimental thermal pain induction protocol was administered at the same time participants completed the task.

The load manipulations were successful in all experiments.

Pain-related interference occurred under the high load condition, but only for the attention span task.

No effect of pain was found on either the attentional switching or divided attention task.

These results suggest that while cognitive load may influence the interruptive effect of pain on attention, this effect may be selective.

Since pain affected the high load version of the n-back task, but did not interrupt performance on attentional switching or dual task paradigms, this means our findings did not completely support our hypotheses.

Future research should explore further the parameters and conditions under which pain-related interference occurs.

    As far as Im concerned it’s simple. When the pain starts my attention is diverted to trying to do whatever I can to minimize the pain The task at hand becomes secondary at best.

      Because pain is considered an emergency in our bodily systems, it’s been deliberately designed to override everything else going on in the body.

      Pain signals are very hard to ignore by design, and that doesn’t change when they are no longer “valid” signals requiring immediate action.
