People with chronic pain frequently experience deficits in working memory (WM) and other cognitive domains [6,33,36,48,57,65,77]. Similar cognitive deficits have been observed in healthy individuals undergoing experimental pain tasks [9,54]. While the pain sensation itself is an important contributor to these deficits, the cognitive and affective correlates are also critical, but poorly understood [17,33,75]. In particular, pain catastrophizing1—a cognitive and emotional process that frequently involves ruminating, magnifying, and feeling helpless about pain—may contribute to WM deficits by competing for the same finite pool of cognitive resources, but this has not been systematically tested [63,70].
