Pain has been found in previous research to have a noticeable effect on people’s ability to perform creative tasks. While limited studies in this field exist, most of this work has focused on convergent thinking through the use of compound remote associates tasks (CRAT). In order to investigate how acute pain might affect divergent creative cognition involving a wider answer space, the current study was conducted using an alternate uses task (AUT) during an algometer-based pain intervention. It was found that acute pain did not have a significant effect on accuracy in the CRAT nor on problem solving abilities in the AUT but notably, participants in the pain condition were more likely to say that they solved problems in the CRAT through insight rather than by an analytical approach. This work demonstrates the need for more research in this field to better understand the relationship between creative cognition and pain.
Methods: Two adults with dyslexia and 4 control adults participated in an auditory gating test using tone pairs. Latencies and Amplitudes for the N100 and P200 responses were recorded and analyzed. Participants were also administered the Abbreviated Torrance Test for Adults (ATTA), a test of creative ability designed to evaluate divergent thinking in individuals. Results were averaged and compared.
Results: The averaged difference in measured N100 amplitudes between tone 1 and tone 2 was significantly larger in the control group compared to the difference observed in the dyslexia group. In particular, one participant with dyslexia who had low scores on a task of rapid word recognition also showed no evidence of gating at the N100 component, whereas the other participant with dyslexia with good word recognition scores showed evidence of intact gating. The averaged difference in measured P200 amplitude between tone 1 and tone 2 was larger in the dyslexia group compared to the control group; however, the difference was small enough to be considered insignificant. The total average ATTA score for the control group was higher than the average of the dyslexia group. This difference in total average was less than one point on a 106-point scale.
Conclusions: Neural sensory gating occurs approximately 100 ms after the onset of a stimulus and is diminished in adults with dyslexia who also have deficits in rapid word recognition. There is a difference in creativity, in terms of divergent thinking, between those with dyslexia and those without (controls scored higher on average); however, the difference is not significant (less than one point). Dyslexia scores were more consistent than controls.
