Attention to food stimuli in binge eating disorder: Electrophysiological evidence.

Attentional biases towards food play an important role in the pathology of binge eating disorder (BED). Later stage electrophysiological potentials (P300, late positive potential) present promising markers of motivated attention with high temporal, albeit low spatial resolution. Complementing this, the N2pc is an earlier-latency component providing the possibility of more directly analyzing visuospatial attention.

Efficacy of a cognitive training based on inhibitory spillover and attribute conditioning: No weight and food intake reductions in adults with overweight and obesity.

Background: Overeating and obesity have been linked to deficient self-control and recent evidence suggests that the inhibitory spillover effect (ISE) may be an effective means to improve self-control. Specifically, it was shown that the ISE increases self-control by transfer of self-control capacity from one domain to another unrelated domain. Against this backdrop, our aim was to reduce hedonic food intake and body weight in non-dieting participants with overweight and obesity by transferring inhibitory control abilities from a food-unrelated domain to the food domain by means of an attribute conditioning procedure in a novel cognitive training (vs.

Modality Matters: Fasted Individuals Inhibit Food Stimuli Better Than Neutral Stimuli for Words, but Not for Pictures.

The current study aimed to evaluate the effect different modalities (pictures and words) of food stimuli have on inhibitory control under different homeostatic states. To this end, the homeostatic state was altered by asking participants to fast for 16 h ( = 67) or eat lunch as usual ( = 76) before completing an online stop-signal task with modal (pictures) and amodal (words) food and valenced-matched non-food stimuli. The inclusion of non-food stimuli allowed us to test the food specificity of the effect.

Effects of exposure to plus-size fashion models on weight-related attitudes in bulimia nervosa: Findings from an exploratory study.

Background And Objectives: Eating disorders are often linked to the internalization of the thin-ideal and weight stigma. The present exploratory study investigates the effects of plus-sized fashion media on weight-related attitudes in bulimia nervosa (BN).

Methods: Women with BN (n=27) and without an eating disorder (n=28) were exposed to 17 pictures of plus-size fashion models.

High-definition turns timing-dependent: Different behavioural consequences during and following cathodal high-definition transcranial direct current stimulation (HD tDCS) in a magnitude classification task.

Neuromodulation with transcranial direct current stimulation (tDCS) can transiently alter neural activity, but its spatial precision is low. High-definition (HD) tDCS was introduced to increase spatial precision by placing additional electrodes over the scalp. Initial evaluations of HD tDCS indicated polarity-specific neurophysiological effects-similar to conventional tDCS albeit with greater spatial precision.

Modifying biased attention towards food stimuli in binge eating disorder: A multi-session training study.

Individuals with binge eating disorder (BED) exhibit a biased attention towards food stimuli. Against this backdrop, the present study with pre-registered design (ID: DRKS00012984) tested whether (a) a training designed to reduce attentional food processing indeed modifies this bias, (b) this reduction is evident in several measures of food-related attention and (c) this is associated with reductions in craving, binge frequency over the past 28 days and calories eaten in a laboratory based bogus taste test. Individuals with BED were randomly allocated to four sessions of either an attentional bias modification training (ABMT; n = 39) or a comparable no-modification control training (CT; n = 27).

Regional specificity of cathodal transcranial direct current stimulation effects on spatial-numerical associations: Comparison of four stimulation sites.

Neuromodulation with transcranial direct current stimulation (tDCS) is an increasingly popular research tool to experimentally manipulate cortical areas and probe their causal involvements in behavior, but its replicability and regional specificity are not clear. This registered report investigated cathodal tDCS effects on spatial-numerical associations (i.e.

Mirror Exposure Training for Adolescents With Anorexia Nervosa (MIRADAN): Cognitive Mechanisms of Body Disturbance - A Study Protocol.

Background: Anorexia Nervosa (AN) is a severe mental illness, which typically develops in adolescence and, if left untreated, often becomes chronic. Body dissatisfaction is a core characteristic of AN. Mirror exposure (ME) is an effective therapeutic technique to tackle body dissatisfaction in adult patients with eating disorders, but there is limited evidence for the effects of ME in adolescence.

Persistent avoidance of virtual food in anorexia nervosa-restrictive type: Results from motion tracking in a virtual stopping task.

Objective: Food avoidance is central to patients with anorexia nervosa-restrictive type (AN-R). Competing accounts in experimental psychopathology research suggest that food avoidance may result from automatic, habitual responses or from elevated inhibitory control abilities. This study investigated behavioral trajectories of food avoidance in a novel virtual reality stopping task.

Body Dissatisfaction Directs Avatar Perception: Embodiment and Selective Visual Attention in Body Mass-Modified Self-Avatars.

Human agents immersed in metaverse technologies such as virtual reality (VR) are routinely disconnected from their actual physical appearance and embodied in another virtual body, referred to as self-avatar. Such body transformations can have implications for patients with eating disorders, or persons with extreme body dissatisfaction (BD). Changes in BD, weight anxiety, or body image are theoretically linked to visual selective attention, which can be measured with eye tracking.

Modal and amodal cognition: an overarching principle in various domains of psychology.

Accounting for how the human mind represents the internal and external world is a crucial feature of many theories of human cognition. Central to this question is the distinction between modal as opposed to amodal representational formats. It has often been assumed that one but not both of these two types of representations underlie processing in specific domains of cognition (e.

Does inhibitory control spill over to eating behaviors? Two preregistered studies of inhibitory spillover effects on food intake and reactions to food stimuli.

Overweight and obesity are worldwide conditions associated with detrimental medical and psychosocial outcomes. As inhibitory control deficits are thought to contribute to weight gain, they are a worthwhile target for new approaches. Previous research has shown that the execution of inhibitory control in one domain leads to a concurrent increase of inhibitory control in another domain, an effect denoted as inhibitory spillover effect (ISE).

Impact of a mental training program for pediatric cancer patients after allogeneic hematopoietic stem cell transplantation or high-dose chemotherapy - Results of a randomized controlled trial.

Objectives: Hematopoietic stem cell transplantation (HSCT) or intensive chemotherapy for the treatment of malignant diseases is a highly distressing experience. The affected person's resilience is crucial to coping with this challenging experience. Experience with resilience-enhancing interventions in children and young adults during cancer therapy is scarce.

Application of the National Comprehensive Cancer Network-distress thermometer in pediatric patients during autologous and allogeneic hematopoietic stem cell transplantation and relationship to blood parameters of the stress axis.

Purpose: Hematopoietic stem cell transplantations (HSCT) are extremely stressful procedures for pediatric patients. The activation of the hypothalamic pituitary adrenocortical axis (HPA) can influence the immune system negatively and therefore the overall outcome. The distress thermometer (DT) is an easy to use tool for the self-assessment of perceived distress.

Reliability of gamified reinforcement learning in densely sampled longitudinal assessments.

Reinforcement learning is a core facet of motivation and alterations have been associated with various mental disorders. To build better models of individual learning, repeated measurement of value-based decision-making is crucial. However, the focus on lab-based assessment of reward learning has limited the number of measurements and the test-retest reliability of many decision-related parameters is therefore unknown.

Practice makes perfect: Restrained eaters' heightened control for food images.

Objective: Restrained eaters (RE) show behaviourally unregulated food intake, which is often explained by a deficit in inhibitory control. Despite evidence for general inhibitory deficits in RE, it remains unclear how the variety of (food) cues in our environment can influence cognitive control.

Method: In this re-analysis, we explored the inhibitory capacity of RE and unrestrained eaters (URE) on a stop-signal task with modal (pictures) and amodal (word) food and non-food stimuli.

Does a white bear help you eat less? The impact of the inhibitory spillover effect on eating behaviour.

Objective: Overweight and obesity are global problems with negative physical, social, and psychological outcomes. Besides other factors, inhibitory control deficits contribute to weight gain and development of overweight. The inhibitory spillover effect (ISE) improves inhibitory control through transfer of inhibitory control capacity from one domain to an unrelated, second domain.

Body exposure and vocal analysis: validation of fundamental frequency as a correlate of emotional arousal and valence.

Introduction: Vocal analysis of fundamental frequency (0) represents a suitable index to assess emotional activation. However, although 0 has often been used as an indicator of emotional arousal and different affective states, its psychometric properties are unclear. Specifically, there is uncertainty regarding the validity of the indices of 0 and 0 (0, 0, and 0) and whether higher or lower 0 indices are associated with higher arousal in stressful situations.

Screening for distress and quality of life in pediatric patients after allogeneic or autologous hematopoietic stem cell transplantation using a self-reporting instrument, blood stress biomarkers and an expert rating scale (PO-Bado).

Objective: Hematopoietic stem cell transplantation (HSCT) is highly distressing and potentially traumatizing for pediatric and young adult patients (PYAP). At present, there is little evidence on their individual burdens.

Methods: In this prospective cohort study, the course of the psychological and somatic distress was investigated on eight observation days (day -8/-12, -5, 0 (day of HSCT), +10, +20, and + 30 before/after HSCT), using the PO-Bado external rating scale and the EORTC-QLQ-C15-PAL self-assessment questionnaire.

Increased insula and amygdala activity during selective attention for negatively valenced body parts in binge eating disorder.

Previous studies indicate that participants with eating disorders show an attentional bias for the negatively valenced body parts of their own body. However, the neural basis underlying these processes has not been investigated. We conducted a preregistered combined functional MRI (fMRI)/eye tracking study and presented 35 women with binge eating disorder (BED) and 24 weight-matched control subjects (CG) with body part images of their own body and a weight-matched unknown body.

Efficacy and mechanisms of change in exposure-based and cognitive stand-alone body image interventions in women with overweight and obesity.

Objective: Body dissatisfaction is highly prevalent in overweight and obesity, while evidence for the efficacy of body image interventions is still scarce. This interventional pilot study investigates the efficacy and mechanisms of change of two stand-alone body image interventions in women with overweight and obesity.

Methods: Women with overweight and obesity (n = 76) were randomly assigned to five weekly sessions of either a mirror exposure (ME) or a cognitive restructuring intervention (CR) or to a wait-list control group (WCG).

Playing with temptation: Stopping abilities to chocolate are superior, but also more extensive.

Cue-specific inhibitory control is assumed to support balanced food intake, but previous studies with established measures showed inconsistent results. We developed a novel kinematic stop task in virtual reality (VR) and report results from trajectory recordings. The primary objective of this explorative study was to assess the interrelationships between validated measures of food-related inhibitory control and novel measures from the VR task.

Facilitation of simultaneous control? A meta-analysis of the inhibitory spillover effect.

Impaired inhibitory control is a core transdiagnostic mechanism in psychopathology. Directly targeting inhibitory control in intervention studies has, however, produced only little improvement. Recently, promising improvements in inhibitory control were shown by capitalizing on the inhibitory spillover effect (ISE).

Mirror exposure in binge-eating disorder: Changes in eating pathology and attentional biases.

Objective: Body image disturbance is crucial in the psychopathology of binge-eating disorder (BED). According to cognitive models of eating disorders, biased attentional processes contribute to the development and maintenance of body image concerns. Mirror exposure constitutes an effective method to improve body image.

Attentional processing of body images in women with overweight and obesity.

Purpose: Despite the claim to integrate body image interventions in obesity treatment, little is known about the mechanisms involved in maintaining body dissatisfaction in persons with overweight and obesity. Therefore, the present study sought to investigate attentional processing of body stimuli in women with overweight and obesity (OW).

Methods: Women with OW (n = 82) and normal weight controls (NW; n = 44) conducted two eye-tracking paradigms.
