Abstract
The reading the mind in the eyes test (RMET) - which assesses the theory of mind component of social cognition - is often used to compare social cognition between patients with schizophrenia and healthy controls. There is, however, no systematic review integrating the results of these studies. We identified 198 studies published before July 2020 that administered RMET to patients with schizophrenia or healthy controls from three English-language and two Chinese-language databases. These studies included 41 separate samples of patients with schizophrenia (total n = 1836) and 197 separate samples of healthy controls (total n = 23 675). The pooled RMET score was 19.76 (95% CI 18.91-20.60) in patients and 25.53 (95% CI 25.19-25.87) in controls (z = 12.41, p < 0.001). After excluding small-sample outlier studies, this difference in RMET performance was greater in studies using non-English v. English versions of RMET (Chi [Q] = 8.54, p < 0.001). Meta-regression analyses found a negative association of age with RMET score and a positive association of years of schooling with RMET score in both patients and controls. A secondary meta-analysis using a spline construction of 180 healthy control samples identified a non-monotonic relationship between age and RMET score - RMET scores increased with age before 31 and decreased with age after 31. These results indicate that patients with schizophrenia have substantial deficits in theory of mind compared with healthy controls, supporting the construct validity of RMET as a measure of social cognition. The different results for English versus non-English versions of RMET and the non-monotonic relationship between age and RMET score highlight the importance of the language of administration of RMET and the possibility that the relationship of aging with theory of mind is different from the relationship of aging with other types of cognitive functioning.

Abstract
Deficits in interpersonal and social functioning are well established in females with Anorexia Nervosa (AN), and are thought to be key features involved in the onset and maintenance of the disease. Growing literature suggests these may be attributed to poor social cognitive processes. This systematic review evaluates whether differences in social cognition exist in adult females with AN. A total of 32 studies that compared females with AN against a healthy control group using social cognitive measures and/or questionnaires were analysed. The majority of studies were deemed to have a low or moderate risk of bias. Overall, empathy appears to be intact in AN, however greater emotion regulation difficulties, elevated alexithymia and reduced emotional awareness are evident in AN. Findings relating to emotion recognition and emotional Theory of Mind were inconsistent. The nature of the task appeared to influence the domains of cognitive ToM and social perception, warranting further research. These findings are discussed within the broader context of social cognitive models and AN rehabilitation.

Abstract
INTRODUCTION Contemporary models of eating disorders (EDs) suggest that EDs are maintained by social-emotional difficulties. However, supporting evidence is derived largely from female, clinic-based samples. This study, which refrained from gender specific inclusion criteria, aimed to improve understanding of social-emotional functioning in a large community-based analogue sample of young adults aged 16-26. METHODS Five hundred and forty-four participants (85.1% female; mean age 21, SD = 4.3) completed the Eating Attitudes Test, Clinical Outcomes in Routine Evaluation, Difficulties in Emotion Regulation Scale, Social Phobia Inventory, Revised Social Anhedonia Scale, Toronto Alexithymia Scale, and the Reading the Mind in the Eyes Task. RESULTS One hundred and sixty-four participants scored over the EAT-26 clinical cutoff, and a two-way multivariate analysis of covariance found a medium-sized, statistically significant main effect of group on social-emotional functioning (F(5, 530) = 6.204, p ≤ .001, Wilks' Λ = 0.945, d = 0.48.), suggesting that individuals with significant ED symptoms found it more challenging to notice, label, and regulate emotions in themselves and recognize emotions in others. Gender did not significantly impact social-emotional functioning (F(10, 1,060) = 0.556, p = .850, Wilks' Λ = 0.990), and there was no significant group by gender interaction (F(10, 1,060) = 0.688, p = .737, Wilks' Λ = 0.987). CONCLUSION These data suggest that the social-emotional difficulties, particularly with emotion recognition and regulation, present in clinical samples are also evident in young people of all genders with significant disordered eating. Future work could aim to recruit an even more gender-diverse community sample to further elucidate social-emotional functioning in individuals in the community with significant disordered eating.

Abstract
This paper presents a broad perspective on how mental disease relates to the different evolutionary strategies of men and women and to growth, metabolism, and mitochondria—the enslaved bacteria in our cells that enable it all. Several mental disorders strike one sex more than the other; yet what truly matters, regardless of one’s sex, is how much one’s brain is “female” and how much it is “male”. This appears to be the result of an arms race between the parents over how many resources their child ought to extract from the mother, hence whether it should grow a lot or stay small and undemanding. An uneven battle alters the child’s risk of developing not only insulin resistance, diabetes, or cancer, but a mental disease as well. Maternal supremacy increases the odds of a psychosis-spectrum disorder; paternal supremacy, those of an autism-spectrum one. And a particularly lopsided struggle may invite one or the other of a series of syndromes that come in pairs, with diametrically opposite, excessively “male” or “female” characteristics. By providing the means for this tug of war, mitochondria take center stage in steadying or upsetting the precarious balance on which our mental health is built.

Abstract
Investigations of disordered eating in the athlete population tend to focus on females and the influence of sport level. This leaves unanswered whether, and how, team interdependence (i.e., whether the competition is engaged with one person or as a team) may differentially impact male athletes. In the present study, we recruited a sample of non-athletes, individual athletes, and team athletes and examined the interaction of gender and teammate interdependence on established psychosocial risk factors for disordered eating, including social phobia, alexithymia, and emotion regulation. Although we identified a significant main effect of gender, there was no main effect of team type, nor was there a significant interaction of gender and team type. Using descriptive discriminant analysis, these variables significantly discriminated between genders. Women were defined by higher scores than men on drive for thinness, body dissatisfaction, and emotion recognition and men were defined by relatively higher scores on emotion dysregulation and binge eating. When we combined all athletes and compared them with non-athletes, a significant interaction of gender and athlete status emerged such that female athletes, compared to male athletes and women non-athletes, were defined by higher scores on drive for thinness, emotion dysregulation, and binge eating. Conversely, male athletes, compared to female athletes, were defined by greater difficulty identifying feelings and body dissatisfaction. Non-athletes were not well defined by the discriminant function. These results highlight that emotional processes convey risk of eating disorders in men and women, particularly in athletes, and these risk factors are not uniform.

Abstract
Context: Patients with eating disorders (EDs) may have a lower mentalization ability. To the best of our knowledge, no meta-analysis has so far addressed the multidimensional mentalization profile within these patients.Objective: To summarize the existing evidence of the mentalization profile and its association with EDs.Data sources: We searched for articles in PsychINFO, Embase and PubMed using the search terms mentalization, reflective function, adult attachment interview, alexithymia, Toronto Alexithymia Scale, eye test, Reading the Mind in the Eyes Test, Theory of Mind, mind-mindedness, mind-blindness, facial expression recognition, metacognition, ED, anorexia nervosa (AN) and bulimia nervosa (BN).Studies included: Quantitative studies including diagnosed patients with an ED, healthy controls (HCs) and relevant test methods.Data synthesis: Forty-four studies were included. Nine studies were eligible for the meta-analysis. Significantly lower mentalization ability about oneself was found in patients with an ED when compared to HCs. Groups were more comparable when dealing with mentalization ability of others. Non-significant but clinically relevant results include a tendency for a lower mentalization ability in patients with AN compared to patients with BN.Conclusion: The mentalization profile is complex and varies across dimensions of mentalization in patients with an ED. Different degrees of mentalization between various EDs were found, implying the necessity for further research on mentalization profiles in different ED diagnoses. The sparse existing literature was a limitation for this meta-analysis, emphasizing that further research on the mentalization profile in patients with EDs is needed.

Abstract
OBJECTIVE Although men comprise 25% of persons with eating disorders (EDs), most research has focused on understanding EDs in women. The theoretical framework underlying common ED treatment has not been rigorously tested in men. The purpose of this study was to compare the interconnectivity among ED symptoms in men versus women. METHOD Participants (N = 1,348; 50% men) were individuals with anorexia nervosa, bulimia nervosa, binge-eating disorder, or other specified feeding or eating disorder who were users of Recovery Record, a smartphone app for monitoring ED symptoms. Participants were matched on age and duration of illness. Network analysis was used to create networks of symptoms for both sexes. Strength centrality, network stability, and bootstrapped centrality differences were tested. The network comparison test (NCT) was used to identify sex differences between networks. Key players analysis was used to compare fragmentation of each network. RESULTS For both sexes, items related to binge eating and restricting emerged as highest in strength centrality. The NCT identified significant differences global strength (p = .03) but not network invariance (p = .06) suggesting that although the structure of the networks was not statistically different, the strength of the connections within the network was greater for women. Key players analysis indicated that both networks were similarly disrupted when important nodes within the network were removed. DISCUSSION Findings suggested that there are more similarities than differences in networks of EDs in men and women. Results have important clinical implications by supporting theoretical underpinnings of cognitive-behavioral models of EDs in both men and women.

Abstract
Emotional difficulties have been observed in individuals with eating disorders across awide range of studies, including poor interoceptive awareness, confusion of emotional states and difficulties with emotional language. Literature has linked these difficulties with emotional functioning as being an important factor related to the core aetiology ofeating disorders, however limited knowledge exists to how this impacts on professionalability to engage patients within treatment as a result of such dysfunction. Using aqualitative design this paper explores how facets of Emotional intelligence (EI) are related to the experience of an eating disorder. The study sampled a total of 32 participants with either a professional background working with eating disorders (n=27)or participants with personal lived experience (n=5), with a number of the participants (n=13) identified as having dual roles. The findings of the study show that aspects of EIsuch as emotional regulation and lack of an emotional language are considered to beat the core of the onset and maintenance of these disorders. Additional aspects of emotional awareness and expression were found to be related to treatment disengagement and difficulties. Building on previous literature, this paper found suchemotional deficits as a transdiagnostic issue rather than specifically anorexia nervosa. Furthermore, such dysfunction was seen by professionals to have a considerable impact on therapeutic relationships and successful treatment. These findings provide insight into the potential applications that EI may have in addressing aspects of theeating disorder to create better outcomes for treatment and intervention models.

Abstract
Findings from studies investigating cognitive flexibility in eating disorders (EDs) are inconsistent, and although neuropsychological tests are commonly used to measure these skills, they may not be particularly effective in predicting everyday functioning. Also, extant studies have largely focused on flexibility in anorexia nervosa (AN), with assessments targeting general rather than specific flexibility, and cognitive, rather than behavioral flexibility. Knowledge regarding ED specific flexibility and flexibility in bulimia nervosa (BN) and binge eating disorder (BED) is still scarce. The aim of this study was to develop and validate a novel measure assessing general and ED specific flexibility in a diagnostically diverse sample, and in healthy controls (HCs). A sample of 207 adult individuals with EDs (55% AN, 29% BN, 16% BED) and 288 HCs responded to an online, 51-item, pilot questionnaire on ED specific and general flexibility. In addition, participants completed the shift subscale from the Behavior Rating Inventory of Executive Function Adult version (BRIEF-A), and the Eating Disorder Diagnostic Scale (EDDS). A principal component analysis (PCA) in the clinical sample yielded a 36-item, three-factor solution capturing general flexibility, flexibility related to food and exercise, and flexibility concerning body shape and weight. Results showed that the measure had good to excellent internal consistency, and good convergent validity. A confirmatory factor analysis (CFA) using data from HCs revealed good fit indexes, supporting the original factor solution. A receiver operating characteristics analysis (ROC) demonstrated excellent accuracy in distinguishing scores from those with and without EDs. A cutoff score of 136 yielded the most balanced sensitivity and specificity. Significant differences in general and ED specific flexibility were found between individuals with and without EDs. Overall, HCs achieved the highest flexibility scores, followed by those with BED, BN, and AN. In sum this novel measure, the Eating Disorder Flexibility Index (EDFLIX) questionnaire, was found to be reliable and valid in the assessment of cognitive and behavioral flexibility, with results offering support for the conceptual distinction between general and ED related flexibility. The study also provides strong evidence for the discriminant validity of the EDFLIX with results revealing significant differences in flexibility in people with and without EDs. In addition, significant differences in flexibility also emerged when comparing diagnostic groups, indicating the utility of the assessment instrument for classification purposes.

Abstract
Difficulties in emotion regulation (ER) are common in females with eating disorders (ED). However, no study to date has analyzed ER in males with ED. In the study at hand, we assessed ER in males with ED and compared results to both females with ED and healthy controls (HC). We also examined associations between ER difficulties, personality, and psychopathology. A total of 62 males with ED were compared with 656 females with ED, as well as 78 male and 286 female HC. ER was assessed by means of the Difficulties in Emotion Regulation Scale (DERS). We found that males and females with ED showed greater ER difficulties compared to HC. Pronounced general psychopathology was a shared factor associated with higher ER difficulties in both males and females with ED. However, whereas higher novelty seeking, higher cooperativeness, lower reward dependence, and lower self-directedness were related to higher ER difficulties in females with ED, lower persistence was associated with ER difficulties in males with ED. In sum, males and females with ED show similar ER difficulties, yet they are distinct in how ER deficits relate to specific personality traits. Research on strategies promoting ER in the treatment of males with ED is warranted.

Abstract
Compulsivity is a central feature of obsessive-compulsive and addictive disorders, which share considerable overlap with excessive eating in terms of repetitive behavior despite negative consequences. Excessive eating behavior is characteristic of several eating-related conditions, including eating disorders [bulimia nervosa (BN), binge eating disorder (BED)], obesity, and food addiction (FA). Compulsivity is proposed to be driven by four distinct cognitive components, namely, contingency-related cognitive flexibility, task/attentional set-shifting, attentional bias/disengagement and habit learning. However, it is unclear whether repetitive behavior in eating-related conditions is underpinned by deficits in these cognitive components. The current mini-review synthesizes the available evidence for performance on compulsivity-related cognitive tasks for each cognitive domain among populations with excessive eating behavior. In three of the four cognitive domains, i.e., set-shifting, attentional bias and habit learning, findings were mixed. Evidence more strongly pointed towards impaired contingency-related cognitive flexibility only in obesity and attentional bias/disengagement deficits only in obesity and BED. Overall, the findings of the reviewed studies support the idea that compulsivity-related cognitive deficits are common across a spectrum of eating-related conditions, although evidence was inconsistent or lacking for some disorders. We discuss the theoretical and practical importance of these results, and their implications for our understanding of compulsivity in eating-related conditions.

Abstract
Background: Recent models of eating disorders (EDs) have proposed social and emotional difficulties as key factors in the development and maintenance of the illness. While a number of studies have demonstrated difficulties in theory of mind and emotion recognition, little is known about empathic abilities in those with EDs. Further, few studies have examined the cognitive-affective empathy profile in EDs. The aim of this systematic review and meta-analysis was to provide a synthesis of empathy studies in EDs, and examine whether those with EDs differ from healthy controls (HC) on self-reported total, cognitive, and affective empathy. Methods: Electronic databases were systematically searched for studies using self-report measures of empathy in ED populations. In total, 17 studies were identified, 14 of which could be included in the total empathy meta-analysis. Eight of the 14 studies were included in the cognitive and affective empathy meta-analyses. Results: Meta-analyses showed that while total empathy and affective empathy scores did not differ between those with anorexia nervosa (AN) and HC, those with AN had significantly lower cognitive empathy scores compared to HCs (small effect size). Meta-analyses of Interpersonal Reactivity Index sub-scores revealed that AN had significantly lower Fantasy scores than HC (small effect size), indicating that those with AN have more difficulty in identifying themselves with fictional characters. Only 3 studies examined empathy in those with bulimia nervosa (BN) or binge eating disorder (BED). Conclusions: The lowered cognitive empathy and intact affective empathy profile found in AN is similar to that found in other psychiatric and neurodevelopmental conditions, such as autism spectrum disorder (ASD). These findings add to the literature characterizing the socio-emotional phenotype in EDs. Future research should examine the influence of comorbid psychopathology on empathy in EDs.

Abstract
Sex-specific brain and cognitive deficits emerge with malnutrition, some infectious and neurodegenerative diseases, and often with prenatal or postnatal toxin exposure. These deficits are described in disparate literatures and are generally not linked to one another. Sexual selection may provide a unifying framework that integrates our understanding of these deficits and provides direction for future studies of sex-specific vulnerabilities. Sexually selected traits are those that have evolved to facilitate competition for reproductive resources or that influence mate choices, and are often larger and more complex than other traits. Critically, malnutrition, disease, chronic social stress, and exposure to man-made toxins compromise the development and expression of sexually selected traits more strongly than that of other traits. The fundamental mechanism underlying vulnerability might be the efficiency of mitochondrial energy capture and control of oxidative stress that in turn links these traits to current advances in neuroenergetics, stress endocrinology, and toxicology. The key idea is that the elaboration of these cognitive abilities, with more underlying gray matter or more extensive inter-modular white matter connections, makes them particularly sensitive to disruptions in mitochondrial functioning and oxidative stress. A framework of human sexually selected cognitive abilities and underlying brain systems is proposed and used to organize what is currently known about sex-specific vulnerabilities.

Abstract
Background Large variability in tests and differences in scoring systems used to study central coherence in eating disorders may lead to different interpretations, inconsistent findings and between study discrepancies. This study aimed to address inconsistencies by collating data from several studies from the same research group that used the Rey Osterrieth Complex Figure Test (Rey Figure) in order to produce norms to provide benchmark data for future studies. Method Data was collated from 984 participants in total. Anorexia Nervosa, Bulimia Nervosa, recovered Anorexia Nervosa, unaffected family members and healthy controls were compared using the Rey Figure. Results Poor global processing was observed across all current eating disorder sub-groups and in unaffected relatives. There was no difference in performance between recovered AN and HC groups. Conclusions This is the largest dataset reported in the literature and supports previous studies implicating poor global processing across eating disorders using the Rey Figure. It provides robust normative data useful for future studies.

Abstract
OBJECTIVE Deficits in theory of mind (ToM), ability to infer mental states of others, can play a significant role in interpersonal difficulties and/or unawareness of illness observed in AN and other eating disorders including bulimia Nervosa (BN). METHOD Current meta-analysis aimed to summarize available evidence for deficits in ToM in AN and BN and examine the effects of number of study-level variables on observed findings. In this meta-analysis, 15 studies (22 samples with eating disorders) investigating ToM performances of 677 individuals with AN or BN and 514 healthy controls were included. RESULTS AN was associated with significant deficits in ToM (d = 0.59) which were more pronounced in the acute patients (d = 0.67). Small sized deficits in ToM were observed in BN (d = 0.34) and recovered AN (d = 0.35). Both cognitive perspective-taking (ToM-PT) (d = 0.99) and decoding mental states (ToM-decoding) (d = 0.61) aspects of ToM were impaired in acute AN. ToM-decoding impairment in BN was modest. There was no evidence for significant ToM-PT deficit in BN. Several study-level variables including longer duration of illness, lower BMI, and depressive symptoms were associated with more severe deficits in ToM in AN. DISCUSSION ToM deficits, particularly in ToM-PT, can be a specific feature of AN but not BN. ToM impairment can contribute to poor insight, treatment resistance, and social impairment in AN. © 2016 Wiley Periodicals, Inc. RESUMEN META ANÁLISIS DE LA TEORÍA DE LA MENTE EN ANOREXIA NERVOSA Y BULIMIA NERVOSA: ¿Un deterioro de la toma de perspectiva cognitiva en Anorexia Nervosa? OBJETIVO Las deficiencias en la teoría de la mente (ToM), la habilidad parar inferir los estados mentales de otros, pueden jugar una función significativa en las dificultades interpersonales y/o falta de reconocimiento de la enfermedad observada en Anorexia Nervosa (AN) y otros trastornos de la conducta alimentaria incluyendo la Bulimia Nervosa (BN). MÉTODO Los meta análisis actuales dirigidos a resumir la evidencia disponible sobre el déficit en ToM en AN y BN y examinar los efectos de un número de variables a nivel estudio en los resultados observados. En este meta análisis fueron incluidos 15 estudios (22 muestras con trastornos alimenticios) investigando la función de ToM de 677 individuos con AN o BN y 514 controles sanos. RESULTADOS La AN fue relacionada con déficit significativo en ToM (d=0.59) los cuales fueron pronunciados en los pacientes agudos (d=0.67). Se observaron déficits de tamaño pequeño en BN (d=0.34) y AN recuperada (d=0.35). La toma de perspectiva cognitiva (ToM-PT) (d=0.99) y la descodificación de los procesos mentales (descodificación de ToM) (d=0.61) fueron deteriorados en la AN aguda. El deterioro en la descodificación de ToM en BN fue moderado. No se encontró evidencia significativa de déficit en ToM-PT en BN. Algunas variables a nivel estudio incluyendo la larga duración de la enfermedad, índice de masa corporal (IMC) bajo y síntomas depresivos fueron asociados con mayores déficit severos en ToM en AN. DISCUSIÓN: El déficit en ToM, particularmente en ToM-PT puede ser una característica específica en la AN pero no en la BN. El deterioro en la descodificación de ToM puede contribuir a mala percepción, resistencia al tratamiento y deterioro social en AN. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2016; 49:739-749).

Abstract
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 ⩽ 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 ⩽ 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 non-significant 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.

Abstract
OBJECTIVE The aim of the study was to assess social cognition in community patients suffering from anorexia nervosa (AN) compared to healthy controls. METHODS 25 women diagnosed with AN and 25 women matched for education level and age were involved in the study. Both subject groups were assessed using a set of validated experimental tasks, such as the facial expression recognition test, short recognition memory test for faces, 'Reading the mind in the eyes' test. Patients were assessed for symptoms of: eating disorder (the eating attitudes test-EAT-26), OCD (the Yale-Brown obsessive compulsive scale-Y-BOCS) and depression (Beck depression inventory-BDI). The research hypothesis indicated that patients suffering from anorexia represent no significant difference in social cognitive functioning in comparison to the healthy controls. These assessment scales were used to identify whether there are any problems according to social cognitive functioning especially emotion recognition and theory of mind (ToM). The primary outcome assessment was to identify social cognitive deficits in anorexic outpatients and secondary outcome was to verify whether these problems in emotional functioning found in women in acute phase of AN are state or trait effects. RESULTS Anorexic patients showed significantly higher scores on EAT-26, BDI and Y-BOCS. No significant differences were found in performance of social cognitive tests and facial perception test. DISCUSSION No marked alterations were found in social cognitive functioning in community patients with average body mass index (BMI) of 17.6. This may indicate that social cognition is a very complex construct to be reliably measured in anorexia nervosa considering relatively limited psychometric data for many social cognitive tasks. Further longitudinal studies are needed to untangle ongoing controversy whether social cognitive deficits in AN could be state or trait related.

Abstract
OBJECTIVE This review aims to examine the impact of depressive symptoms on the assessment of cognitive flexibility, central coherence, and decision-making in individuals with anorexia nervosa (AN). METHOD An online search was carried out using PubMed and PsycInfo. Articles were selected for review if they were published in English between 1990 and 2014 and used the Wisconsin Card Sorting Test, the Trail Making Task parts A and B, the Brixton Test, the Rey-Osterrieth Complex Figure Test, and/or the Iowa Gambling Task. RESULTS Sixty-two studies were included. Thirty (48%) of the studies statistically assessed the association between depression and neurocognition in AN versus healthy controls. Where significant correlations were found, it became clear that the more serious the depression, the greater the neuropsychological impairment. Only six (10%) studies examined whether increased depressive symptoms were able to eliminate the differences between individuals with AN and healthy controls, and one study found that depressive symptoms did eliminate group differences in cognitive flexibility and decision-making. DISCUSSION Only a subgroup of articles on neuropsychology in AN adjusted for depression. However, given the role of depression that some articles suggest, future studies should pay closer attention to the evaluation of this potential confounder.

Abstract
Experimental research, supported by systematic reviews, establishes that people with eating disorders have emotional difficulties in terms of recognising, regulating and expressing their emotions. These emotional difficulties contribute to poor social functioning and problems with relationships. The existing literature includes a broad range of studies, many of which have utilised self-report measures, but experimental studies of emotions in eating disorders are still limited. The primary aim of this paper is to highlight gaps in the clinical research on emotions in eating disorders, focusing on experimental investigations from our lab and highlighting potentially useful future directions for further basic research and its translation into new developments in treatment and prevention. Recent findings using experimental paradigms to study the expression of emotions along with neuroimaging research exploring differences in facial emotion processing are discussed, and clinical implications are presented.

Abstract
Research on emotional functioning, body dissatisfaction, and disordered eating in males is predominated by studies of negative affect and emotion regulation. Other aspects of emotional functioning, namely emotion recognition and attentional biases toward emotional stimuli, have received little empirical attention. The present study investigated the unique associations between different aspects of men's emotional functioning and their disordered eating attitudes, muscularity dissatisfaction, and body fat dissatisfaction. Results from 132 male undergraduates showed that muscularity dissatisfaction was uniquely associated with both emotion regulation difficulties and an attentional bias toward rejecting faces. Body fat dissatisfaction was not uniquely associated with any aspect of emotional functioning. Disordered eating was uniquely associated with emotion regulation difficulties. Collectively, the results indicate differences in the patterns of associations between men's emotional functioning and their body dissatisfaction and disordered eating.
