“…However, it is clear from both the present review and an earlier review of set-shifting abilities in children [10], that a lack of data in this area currently limits us from drawing firm conclusions about the profile of children and adolescents with AN. Further research is therefore needed to firstly confirm the neurocognitive profile of young group with AN, and then secondly to determine whether remedial treatments are required in this population.…”

Objectives: It is hypothesised that Weak Central Coherence (superior attention to detail with poorer bigger picture thinking) is a possible endophenotype for Anorexia Nervosa (AN). Currently the neuropsychological profile of children and adolescents with AN in unclear. The present review aimed to summarise the available literature with regards to the central coherence abilities of children and adolescents with AN, and clarify their neuropsychological profile.Method: The search found seven eligible studies. Meta-analyses were not possible due the variation in tasks used.Results: Evidence of less efficient global processing in children with AN was observed in a number of studies. The strongest evidence was observed from studies using the Rey Osterrieth Complex Figures Test (ROCFT). A visual comparison of ROCFT from child and adult AN studies highlighted similarities in global processing profiles. Conclusions:Evidence of inefficient global processing was observed across a number of studies. However methodological flaws in the current literature were highlighted and made interpretation difficult. These are discussed and recommendations for future research are made.

“…The findings of this study suggesting that there are in fact no differences in the perception of sweetness or fat intensity between people with AN and HC indicates that the documented aversion to this stimuli in individuals with AN reflects subjective perception, rather than objective taste alterations. Instead, sweetness and fat avoidance in AN may instead be driven by the cognitive resistance and inflexibility documented in this population (Lang, Stahl, Espie, Treasure, & Tchanturia, 2014; Tchanturia et al, 2012; Westwood, Stahl, Mandy, & Tchanturia, 2016). …”

ObjectiveThere is evidence for altered processing of taste in anorexia nervosa, particularly in the areas of reward processing and hedonic sensitivity. However, research on whether people with anorexia nervosa identify taste stimuli accurately, known as taste sensitivity, has yielded mixed findings. The objective of this study was to synthesize the literature on taste sensitivity in this disorder to provide a basis for future discussion on whether altered taste sensitivity may be also implicated in wider atypical taste processing in anorexia.MethodElectronic databases were searched systematically to identify published research examining taste sensitivity in anorexia. Search terms were “anorexia nervosa”, or “eating disorder”, combined with “taste”. 18 studies met inclusion criteria.ResultsThe review of the findings suggest that individuals with AN may experience reduced taste sensitivity that may improve following recovery. However, there was a significant variability in results across studies, potentially reflecting methodological problems including low sample sizes, experimental designs, and uncontrolled confounding variables. Discussion: This review suggests that altered taste sensitivity could represent a component in the wider altered taste processing observed in anorexia nervosa. However, the heterogeneity of findings highlight the need for future research to consider methodological issues raised by this review.

“…Limits included English-language, peer-reviewed articles. Reference lists of eligible papers were also screened, as were existing systematic reviews related of set-shifting in either ASD or AN (Roberts et al 2007;Lang et al 2014;Tchanturia, 2015;Landry & Al-Taie, 2016).…”

“…A systematic review of set-shifting ability, comparing adults with AN with HCs identified five papers employing the Wisconsin Card Sorting Test (WCST) (Heaton et al 1993), a widely used measure of set-shifting, with a meta-analysis reporting a significant small effect size (d = 0.36; Roberts et al 2007). A further meta-analysis of studies in children and adolescents with AN (Lang et al 2014), however, found a non-significant pooled effect size (d = 0.20). A more recent study comparing children and adolescents with AN with HCs using a larger sample size (AN = 41, HC = 43) found that young people with AN made significantly more perseverative errors than HCs (d = 0.49; Lang et al 2015a), suggesting that this cognitive profile is present early on in the disorder before the effects of starvation become prominent.…”

The set-shifting profiles of anorexia nervosa and autism spectrum disorder using the Wisconsin Card Sorting Test: a systematic review and meta-analysis

et al. 2016

Difficulties in set-shifting are commonly reported in both autism spectrum disorder (ASD) and anorexia nervosa (AN) populations. Despite this, it is not known whether this cognitive profile persists across different ages, or whether the profiles seen in ASD and AN are comparable. This systematic review and meta-analyses aimed to compare the set-shifting profiles, as measured by the Wisconsin Card Sorting Test (WCST) in adults and younger people with either ASD or AN, relative to healthy controls (HCs) and to statistically compare performance on the WCST between ASD and AN. In all, 24 studies on ASD and 22 studies on AN were identified. In ASD, there were significant differences between the clinical group and HCs, with the ASD group making significantly more perseverative errors, indicating greater difficulty in set-shifting [pooled effect size of d = 0.67, 95% confidence interval (CI) 0.53-0.81, p 4 0.001]. This effect was consistent across the age span. For AN studies, there was a significant difference between adults with AN and HCs (d = 0.52, 95% CI 0.36-0.68, p 4 0.001) but a non-significant effect in child studies (d = 0.25, 95% CI −0.05 to 0.55, z = 1.66, p = 0.096). Meta-regression indicated no effect of diagnosis (AN or ASD) on performance in adult studies but there was a nonsignificant trend (p = 0.053) towards children with ASD performing worse than children with AN. While difficulties with set-shifting appear to be stable in ASD, there may be differences between children and adults with AN, which warrant further investigation.
