“…However, objective measures of attention to health-related stimuli have yielded less consistent findings. For symbolic material (e.g., illness words), some studies have found increased interference on the emotional Stroop task in patients with MUS (e.g., Afzal et al, 2006;Lim and Kim, 2005;Witthöft et al, 2006). These effects may be attributable to increased avoidance of health-threat rather than engagement with it (De Ruiter and Brosschot, 1994), however, or stimulus negativity more generally (Posserud et al, 2009).…”

a b s t r a c tThe relationship between the conscious experience of physical symptoms and indicators of objective physiological dysfunction is highly variable and depends on characteristics of the person, the context and their interaction. This relationship often breaks down entirely in the case of "medically unexplained" or functional somatic symptoms, violating the basic assumption in medicine that physical symptoms have physiological causes. In this paper, we describe the prevailing theoretical approach to this problem and review the evidence pertaining to it. We then use the framework of predictive coding to propose a new and more comprehensive model of the body-symptom relationship that integrates existing concepts within a unifying framework that addresses many of the shortcomings of current theory. We describe the conditions under which a close correspondence between the experience of symptoms and objective physiology might be expected, and when they are likely to diverge. We conclude by exploring some theoretical and clinical implications of this new account.

“…Some studies have found that MUS patients attend more to illness-relevant stimuli than controls [23][24][25], although this has proved difficult to replicate [26][27][28][29][30]. In terms of more direct measures of body-focused attention, one study found that high SSAS scorers were poorer than low scorers at detecting physiological events (heartbeats), suggesting an attentional deficit in the former [31]; two other studies have found no relationship between SSAS scores and heartbeat detection, however [32,33].…”

“…In addition, a large number of studies found that patients with MUSs and people suffering from common HCs also show increased selective attention for external information related to their HCs, including pain (for reviews, see Refs. [8,11,12]). Likewise, several studies have linked symptom reporting with increased attention to SEN [13][14][15][16].…”
