“…With respect to body-related stimuli and corresponding with previous findings, 91 a bias towards the own body and towards ugly body parts 49,50 was found to be stronger in individuals with BED than in obese controls. 47 In addition to attentional alterations, individuals with BED showed pronounced difficulties in foodrelated response inhibition compared with obese and normal-weight controls 42,43,48 as well as altered activation patterns in prefrontal and orbitofrontal brain regions (e.g., Refs. 92 Furthermore, body dissatisfaction might be additionally increased by difficulties in attending to positively valenced, body-related information, 45 while first evidence suggests that, contrary to BN, a maladaptive mental representation of the bodily self could be ruled out in BED.…”

“…Mental rotation deficits have been identified in disorders including unipolar depression (Rogers et al, 2002), schizophrenia (Quee, Eling, van der Heijden, & Hildebrandt, 2011), and Williams Syndrome (Stinton, Farran, & Courbois, 2008). Bulimia nervosa patients have also been found to be impaired on mental transformations of their own body, but not on transformations of external objects (Urgesi et al, 2011). Observer perspective is also associated with poor outcomes in PTSD (McIsaac & Eich, 2004) and depression (Kuyken & Moulds, 2009).…”

Mental imagery is an under-explored field in clinical psychology research but presents a topic of potential interest and relevance across many clinical disorders, including social phobia, schizophrenia, depression, and post-traumatic stress disorder. There is currently a lack of a guiding framework from which clinicians may select the domains or associated measures most likely to be of appropriate use in mental imagery research. We adopt an interdisciplinary approach and present a review of studies across experimental psychology and clinical psychology in order to highlight the key domains and measures most likely to be of relevance. This includes a consideration of methods for experimentally assessing the generation, maintenance, inspection and transformation of mental images; as well as subjective measures of characteristics such as image vividness and clarity. We present a guiding framework in which we propose that cognitive, subjective and clinical aspects of imagery should be explored in future research. The guiding framework aims to assist researchers in the selection of measures for assessing those aspects of mental imagery that are of most relevance to clinical psychology. We propose that a greater understanding of the role of mental imagery in clinical disorders will help drive forward advances in both theory and treatment.

Reproducibility of somatosensory spatial perceptual maps

et al. 2012

Various studies have shown subjects to mislocalize cutaneous stimuli in an idiosyncratic manner. Spatial properties of individual localization behavior can be represented in the form of perceptual maps. Individual differences in these maps may reflect properties of internal body representations, and perceptual maps may therefore be a useful method for studying these representations. For this to be the case, individual perceptual maps need to be reproducible, which has not yet been demonstrated. We assessed the reproducibility of localizations measured twice on subsequent days. Ten subjects participated in the experiments. Non-painful electrocutaneous stimuli were applied at seven sites on the lower arm. Subjects localized the stimuli on a photograph of their own arm, which was presented on a tablet screen overlaying the real arm. Reproducibility was assessed by calculating intraclass correlation coefficients (ICC) for the mean localizations of each electrode site and the slope and offset of regression models of the localizations, which represent scaling and displacement of perceptual maps relative to the stimulated sites. The ICCs of the mean localizations ranged from 0.68 to 0.93; the ICCs of the regression parameters were 0.88 for the intercept and 0.92 for the slope. These results indicate a high degree of reproducibility. We conclude that localization patterns of non-painful electrocutaneous stimuli on the arm are reproducible on subsequent days. Reproducibility is a necessary property of perceptual maps for these to reflect properties of a subject's internal body representations. Perceptual maps are therefore a promising method for studying body representations.
