“…A study from our group found not only that SOP and SPP were significantly higher in subjects with an Eating Disorder than in controls, and also compared with patients with depressive/anxiety disorders (Maia et al, 2009).…”

“…The present study also found similar increased sensitivity to punishment and reward in AN as measured by the SPSRQ, but interestingly category learning performance was only associated with alterations in punishment sensitivity. AN individuals have traditionally been associated with perfectionism and high motivation to perform well (Bachner-Melman, Lerer et al, 2007; Castro-Fornieles, Gual et al, 2007; Kaye, 2008; Nilsson, Sundbom et al, 2008; Peck and Lightsey, 2008; Wade, Tiggemann et al, 2008; Maia, Soares et al, 2009) and it could be possible that fear of punishment or failure have the benefit of higher effort and better performance. Still, biologic abnormalities in AN might prevent that group from performing similar to controls in implicit learning and other cognitive tasks.…”

Objective Recent research has identified specific cognitive deficits in patients with anorexia nervosa (AN), including impairment in executive functioning and attention. Another such cognitive process, implicit category learning has been less studied in AN. This study examined whether implicit category learning is impaired in AN. Method Twenty-one women diagnosed with AN and 19 control women (CW) were administered an implicit category learning task in which they were asked to categorize simple perceptual stimuli (Gabor patches) into one of two categories. Category membership was based on a linear integration (i.e., an implicit task) of two stimulus dimensions (orientation and spatial frequency of the stimulus). Results AN individuals were less accurate on implicit category learning relative to age-matched CW. Model-based analyses indicated that, even when AN individuals used the appropriate (i.e., implicit) strategy they were still impaired relative to CW who also used the same strategy. In addition, task performance in AN patients was worse the higher they were in self-reported novelty seeking and the lower they were in sensitivity to punishment. Conclusions These results indicate that AN patients have implicit category learning deficits, and given this type of learning is thought to be mediated by striatal dopamine pathways, AN patients may have deficits in these neural systems. The finding of significant correlations with novelty seeking and sensitivity to punishment suggests that feedback sensitivity is related to implicit learning in AN.

“…Clinical perfectionism (i.e., the dysfunctional attitude to achieve for excellence despite the occurrence of adverse consequences; Shafran, Cooper, & Fairburn, 2002) was considered a core‐maintaining mechanisms of eating pathology in general (Fairburn et al, 2003) as well as a risk factor for the severity of specific EDs (e.g., bulimia nervosa [BN]; Watson, Steele, Bergin, Fursland e Wade, 2011). Perfectionism was found to be more specific to EDs patients than to other psychiatric conditions (Maia et al, 2009) such as depression or anxiety (Castro‐Fornieles et al, 2007). For instance, perfectionism resulted to be higher in individuals with anorexia nervosa (AN; Cockell et al, 2002; Machado, Gonçalves, Martins, Hoek, & Machado, 2014) and in those with BN (Boisseau,Thompson‐Brenner, Pratt, Farchione, & Barlow, 2013) compared to psychiatric controls.…”

The clinical significance of two major aspects of perfectionism, perfectionistic strivings (PS) and perfectionistic concerns (PC), in eating disorders (EDs) symptoms was well‐established among adults. However, no systematic review has assessed evidence examining associations between both unidimensional and multidimensional perfectionism and EDs in early and middle adolescence. For this aim, three online databases (PsycINFO, Medline and PsycArticle) were searched for articles published until January 2019, and observational studies were considered. Study quality was systematically appraised, and results were summarized using a narrative synthesis approach. Fifty‐one cross‐sectional and 28 longitudinal studies were included. Most studies supported the relationship between perfectionism and EDs, with the majority adopting a unidimensional approach for assessing perfectionism. Among studies that employed multidimensional measures of perfectionism, the majority (n = 11) of evidence supported the relationship between eating symptoms and PC, while fewer (n = 5) studies provided significant unique associations with PS. These findings are consistent with the body of research suggesting the strength of the relationship between PC and EDs was greater than between PS and EDs. It was recommended that preventive interventions should be primarily focused on reducing self‐critical perfectionism, since it resulted to be the most relevant perfectionistic dimension in the development of eating symptoms in adolescents.
