Abstract
Attentional bias toward weight-related stimuli plays a crucial role in the development and maintenance of body image disturbances. However, the temporal dynamics of attentional biases responsible for the previously reported behavioral effects caused by the task-irrelevant but spatial-relevant weight-related stimuli presented in the peripheral visual field among females with high weight dissatisfaction (HWD) remain unclear. The present study combined the modified dot-probe task and event-related potentials to explore the temporal dynamics of spatial attentional biases toward weight-related words among females with HWD. The results showed significantly larger N2pc amplitudes were elicited by fat-related and thin-related words than neutral words only in the HWD group. Moreover, only fat-related words elicited a significant PD for the HWD group, and the PD amplitudes were larger in the HWD group than in the control group. These findings revealed that weight-related words initially captured spatial allocation among females with HWD, and then fat-related words were actively suppressed after the initial capturing.

Abstract
Naturalistic body stimuli are necessary for understanding many aspects of human psychology, yet there are no centralized databases of body stimuli. Furthermore, there are a high number of independently developed stimulus sets lacking in standardization and reproducibility potential, and a general lack of organization, contributing to issues of both replicability and generalizability in body-related research. We conducted a comprehensive scoping review to index and explore existing naturalistic whole-body stimuli. Our research questions were as follows: (1) What sets of naturalistic human whole-body stimuli are present in the literature? And (2) On what factors (e.g., demographics, emotion expression) do these stimuli vary? To be included, stimulus sets had to (1) include human bodies as stimuli; (2) be photographs, videos, or other depictions of real human bodies (not computer generated, drawn, etc.); (3) include the whole body (defined as torso, arms, and legs); and (4) could include edited images, but still had to be recognizable as human bodies. We identified a relatively large number of existing stimulus sets (N = 79) which offered relative variability in terms of main manipulated factors and the degree of visual information included (i.e., inclusion of heads and/or faces). However, stimulus sets were demographically homogenous, skewed towards White, young adult, and female bodies. We identified significant issues in reporting and availability practices, posing a challenge to the generalizability, reliability, and reproducibility of body-related research. Accordingly, we urge researchers to adopt transparent and accessible practices and to take steps to diversify body stimuli.

Abstract
Recent literature has discussed the role of attentional biases towards body-related stimuli. Specific foci have been on those with high levels of body image concerns and female samples. Unfortunately, there has been limited focus on male samples within existing literature. The aim of the current study was to provide a critical synthesis of the findings of existing studies exploring attentional biases in adult males towards body-related stimuli. Critical synthesis of the findings of 20 studies explored four key methodologies: eye-tracking, dot-probe, visual search, and other methodologies (e.g. ARDPEI task). The current review provides evidence of specific attentional biases towards body-related stimuli in adult males experiencing body image concerns. Similar patterns of attentional biases are also demonstrated in males with body image pathologies. However, there appears to be distinct patterns of attentional biases for male and female participants. It is recommended that future research considers these findings and utilises measures developed specifically for male samples. Furthermore, additional variables require further attention, i.e. reasons for engaging in social comparison and/or engaging in physical activity.

Is body dissatisfaction related to an attentional bias towards low weight bodies in non-clinical samples of women? A systematic review and meta-analysis. Body Image 2023; 44:103-119. [PMID: 36563472 DOI: 10.1016/j.bodyim.2022.12.003] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2022] [Revised: 12/07/2022] [Accepted: 12/08/2022] [Indexed: 12/24/2022]
Abstract
Body dissatisfaction is defined as the negative subjective evaluation of one's body and is considered a risk factor for, and symptom of, eating disorders. Some studies show women with high body dissatisfaction display an attentional bias towards low weight bodies; however, this finding is not consistent, and results are yet to be systematically synthesised. We conducted a qualitative and quantitative synthesis of cross-sectional studies investigating the relationship between body dissatisfaction and attentional bias to low weight bodies in non-clinical samples of women. We searched PubMed, Scopus, Web of Science, PsycINFO, ProQuest, and OpenGrey for studies up until September 2022. We identified 34 eligible studies involving a total of 2857 women. A meta-analysis of 26 studies (75 effects) found some evidence from gaze tracking studies for a positive association between body dissatisfaction and attentional bias to low weight bodies. We found no evidence for an association from studies measuring attention using the dot probe task, electroencephalogram (EEG) recording, or the modified spatial cueing task. The results together provide partial support for the positive association between body dissatisfaction and attentional bias to low weight bodies in women. These findings can be used to inform future attentional bias research.

Abstract
BACKGROUND Negative body image is a common psychological phenomenon among Chinese college students meriting investigation. Peers and the media are important factors that negatively influence body image. This study explored the mechanisms of media and peers promoting negative body image among Chinese college students. METHOD Data from 407 college students (173 men and 234 women) were collected using the Revised Social and Cultural Attitude Questionnaire of Appearance, Appearance Comparison Scale, Peer Impact Scale, and Negative Body Image Scale. RESULTS Correlational analysis results demonstrated that media attention was not significantly correlated with negative body image. All other variables were significantly positively correlated. Path analysis results indicated that the direct effect of media attention on negative body image was not significant, while the direct effect of peer impact was significant. In addition, appearance comparison and internalization of the thin ideal acted as a chained indirect effect between negative body image, media attention, and peer impact. CONCLUSIONS The research revealed that focusing on perfect bodies displayed in the media did not produce a negative body image. However, focusing on the media and peer conversations regarding the body caused the participants to compare appearances and internalize ideal body shape standards, leading to negative self-evaluations.

Abstract
A number of psychiatric disorders, including body dysmorphic disorder (BDD), anorexia nervosa, bulimia nervosa, and social anxiety disorder, are characterized by heightened appearance concerns and increased cognitive and perceptual biases toward one’s own physical appearance. In the present study, we examined individual differences in self-reported appearance anxiety and symptoms of BDD in relation to the late positive potential (LPP)—an index of stimulus significance—in response to pictures of oneself, strangers and objects among 83 female college students. The results indicated that the LPP was larger for pictures of oneself compared to pictures of strangers and objects. Further, the Yale–Brown Obsessive-Compulsive Scale Modified for Body Dysmorphic Disorder and Appearance Anxiety Inventory scales both related to an increased LPP to pictures of oneself but not to strangers or objects. The findings suggest that the LPP elicited by pictures of oneself may function as a neural marker of appearance concerns, which could be leveraged to study the development and maintenance of a range of psychiatric disorders characterized by increased appearance concerns.

You See What You Smell: Preferential Processing of Chemosensory Satiety Cues and Its Impact on Body Shape Perception. Brain Sci 2021; 11:brainsci11091152.

Abstract
The current study examines neural responses to satiety- and fasting-related volatiles and their effect on the processing of body shapes. Axillary sweat was sampled with cotton pads from 10 individuals after 12 h of fasting, and after having consumed a standard breakfast. Pure cotton pads served as the control. The chemosensory stimuli were presented to 20 participants (via a constant-flow olfactometer) exclusively, and additionally as context to images of overweight and underweight avatars. EEG was recorded (61 electrodes), and chemosensory (CSERPs; P1, N1, P2, P3) and visual event-related potentials (VERPs; N1, P2, P3a, P3b) were analyzed. The amplitudes of all positive CSERP components differed more strongly from cotton in response to chemosensory satiety cues as compared to fasting cues (P1: p = 0.023, P2: p = 0.083, P3: p = 0.031), paralleled by activity within the middle frontal and temporal gyrus. Overweight compared to underweight body shapes tended to elicit larger VERP P2 amplitudes (p = 0.068), and chemosensory satiety cues amplified the VERP amplitudes in response to any body shape (P2, P3a, P3b; all ps ≤ 0.017) as compared to the cotton control. The results indicate that chemosensory satiety cues transmit complex social information, overriding the processing of analogous visual input.

Abstract
OBJECTIVE The categorical classification of eating disorders (ED) has several limitations, for example, high symptom variability within the diagnosis and limited predictive validity for treatment response. An alternative is classifying individuals with ED based on personality traits, which can reflect underlying etiological mechanisms. We aimed to find latent profiles based on facets of maladaptive and adaptive perfectionism, impulsivity and ED symptoms. METHOD The sample comprised of 274 women-164 had an ED diagnosis and 110 were controls. Two separate latent profile analyses were performed-one on the mixed sample (controls and individuals with ED) and the other on the sample of individuals with ED only. RESULTS We identified a five-class model to be the best fit for the mixed sample. The classes were: (a) moderately impulsive, (b) high functioning, (c) purely perfectionistic, (d) emotionally dysregulated, (e) behaviorally dysregulated. Among the individuals with ED, a four-class solution was found to be the best fit. The classes were very similar in their response patterns on indicator variables to response patterns observed in the mixed sample, except the emotionally and behaviorally dysregulated classes that formed into one class. DISCUSSION In addition to the well-known high-functioning, overcontrolled and undercontrolled classes, two to three undercontrolled classes (moderately impulsive, behaviorally, and emotionally dysregulated class) emerged. Those classes differentiated on perfectionism and impulsivity levels as well as on ED symptom severity and psychiatric comorbidities-all of which may influence maintenance of ED, appropriate treatment choice and therefore treatment response.

Abstract
OBJECTIVE We aimed to investigate the phenotypes of individuals with emotional eating (EE) based on their levels of positive and negative EE, body mass index (BMI), and preoccupation with weight, and to assess differences in eating pathology and emotion regulation (ER) difficulties among them. METHOD A community sample of 605 women (mean age = 29.8 years, SD = 9.6; mean BMI = 23.4 kg/m2 , SD = 4.7) filled out the Positive-Negative Emotional Eating Scale, Eating Disorders Assessment Scale, and Difficulties in Emotion Regulation Scale. Data of BMI, positive EE, negative EE, and preoccupation with body weight were submitted to a latent profile analysis. RESULTS A four-profile model was discovered with normal weight individuals without EE (63%), normal weight individuals with EE (23%), overweight individuals without EE (9%), and obese individuals with EE (5%). A five-profile model was also included, as a class of normal weight individuals with positive EE was found. Obese and normal weight individuals with EE showed the highest level of ER difficulties and eating pathology. Overweight individuals without EE showed moderate levels of eating pathology and low levels of ER difficulties, suggesting that high BMI itself might not be related to eating disorder (ED) psychopathology. Normal weight individuals with positive EE showed low levels of eating pathology, but moderate levels of ER difficulties. DISCUSSION Our results suggest that negative EE could be an important risk factor for disordered eating, independent of BMI. Further, individuals with EE could benefit from learning adaptive ER strategies to prevent the onset or maintenance of ED or weight gain.
