Extraversion and accuracy of aspects of memory for pain in the cold water pressor test.
The role of Erlebnistypus personality features were investigated in 40 healthy subjects, as defined by the Rorschach Comprehensive System by Exner, in determining accuracy in recollecting acute tonic experimental pain, induced by the Cold Water Pressor Test. Multiple-regression analysis revealed that the difference between the number of movement answers and the number of chromatic answers in the Rorschach test, an index of general Extroversion, predicted accuracy in recollecting the qualitative features of pain, defined as affective and evaluative pain scores on the McGill Pain Questionnaire. Also, Extratensive subjects were less accurate than Introversive and Ambitent participants at recollecting sensory scores. The data suggest that general extroversion may have a role in individual differences in the higher cognitive processing of pain comprising pain memory.
