Facial Emotion Recognition Abilities in Women Experiencing Eating Disorders

Abstract

OBJECTIVE: Impairments in facial emotion recognition are an underlying factor of deficits in emotion regulation and interpersonal difficulties in mental disorders and are evident in eating disorders (EDs). METHODS: We used a computerized psychophysical paradigm to manipulate parametrically the quantity of signal in facial expressions of emotion (QUEST threshold seeking algorithm). This was used to measure emotion recognition in 308 adult women (anorexia nervosa [n = 61], bulimia nervosa [n = 58], healthy controls [n = 130], and mixed mental disorders [mixed, n = 59]). The M (SD) age was 22.84 (3.90) years. The aims were to establish recognition thresholds defining how much information a person needs to recognize a facial emotion expression and to identify deficits in EDs compared with healthy and clinical controls. The stimuli included six basic emotion expressions (fear, anger, disgust, happiness, sadness, surprise), plus a neutral expression. RESULTS: Happiness was discriminated at the lowest, fear at the highest threshold by all groups. There were no differences regarding thresholds between groups, except for the mixed and the bulimia nervosa group with respect to the expression of disgust (F(3,302) = 5.97, p = .001, = .056). Emotional clarity, ED pathology, and depressive symptoms did not predict performance (RChange .010, F(1,305) 5.74, p .079). The confusion matrix did not reveal specific biases in either group. CONCLUSIONS: Overall, within-subject effects were as expected, whereas between-subject effects were marginal and psychopathology did not influence emotion recognition. Facial emotion recognition abilities in women experiencing EDs compared with women experiencing mixed mental disorders and healthy controls were similar. Although basic facial emotion recognition processes seems to be intact, dysfunctional aspects such as misinterpretation might be important in emotion regulation problems. AbstractObjective: Impairments in facial emotion recognition are an underlying factor of deficits in emotion regulation and interpersonal difficulties in mental disorders, and are evident in eating disorders (EDs). Methods:We used a computerized psychophysical paradigm to manipulate parametrically the quantity of signal in facial expressions of emotion (QUEST threshold seeking algorithm). This was used to measure emotion recognition in 311 adult women (anorexia nervosa (AN,n=61), bulimia nervosa (BN,n=58), healthy controls (HC,n=130) and mixed mental disorders (mixed,n=59)). The mean age was 22.84 years (SD=3.90). The aim was to establish recognition thresholds defining how much information a person needs to recognize a facial emotion expression and to identify deficits in EDs compared to healthy and clinical controls.

The recognition of facial expressions of emotion in deaf and hearing individuals

“…Krejtz et al (2020) found a marginal, non-significant effect for response times during the categorization of morphed neutral to happy, angry and sad expressions. In the present study, we explicitly instructed our observers to favour accuracy rather than speed, in order to conform to our previous studies comparing different populations (e.g., Richoz et al, 2018;Rodger et al, 2015;Rodger et al, 2018;Wyssen et al, 2019) and the large majority of the literature in affective science. As such, response times could not be analysed here.…”

Mentalizing Self and Other and Affect Regulation Patterns in Anorexia and Depression

“…The findings are less consistent when assessing emotion recognition of others (ToM). Thus, deficits in emotion recognition of others have been found in some studies of patients with AN (Harrison et al, 2009), but not in others when applying ToM measures (Bentz et al, 2017) or other paradigms (e.g., Wyssen et al, 2019).…”

Psychometric Properties and Differential Item Functioning of a Web-Based Assessment of Children’s Emotion Recognition Skill

“…They found that children with ADHD were less sensitive to both positive and negative emotions. Another study by Wyssen et al (2019) used the Difficulties with Emotion Regulation Scale (DERS), developed by Gratz and Roemer (2004), to compare recognition of negative emotions among women experiencing eating disorders with ER among healthy women and women experiencing mood and anxiety disorders. These studies contribute to our understanding of social cognitive challenges in clinical populations.…”
