After images and pain tolerance: a descriptive study on their interrelationship.
After images are based on physiological processes, they can also be treated as subjective phenomena with a psychological meaning. This statement also applies to pain. The basic working hypothesis of this study concerned the relationship between the two phenomena. Forty-one respondents (23 females, 18 males, age range 20-45 years) were given the Cold Pressor Test and the Serial After Image Technique. The data analysis was done by means of cross-tables and an exploratory optimal scaling program (OVERALS). Three pain tolerance groups (low, medium, high) could be differentiated fairly well on the basis of the after image characteristics of the respondents. Pain intolerant respondents more frequently had small and "immature" after images, whereas highly pain tolerant respondents had more large and "mature" after images. The implications of these results for a bio-psycho-social theoretical frame of reference for pain are discussed.
