- Abstract
- This study examines the selective impact of chronic pain on memory functioning in a recognition task. Thirty chronic pain patients and 30 healthy control subjects performed a yes-no word recognition test. The contribution of recollection and familiarity to both groups' performance was compared by means of the Remember/Know (R/K) procedure, which distinguishes recognition based on the recollection of the encoding episode (R responses) and recognition accompanied by a feeling of familiarity (K responses). Chronic pain patients showed a decrease in recollection together with an increase in familiarity: indeed, they reported less R and more K responses than control subjects. This pattern of performance was not related to the overall recognition ability. These findings are consistent with the hypothesis of the attentional cost of chronic pain, suggesting a selective impact of chronic pain on the most attention-demanding cognitive processes, such as recollection. This study emphasises the relevance of specific procedures distinguishing the underlying components of memory functioning rather than solely global indicators.
