Loneliness and the recognition of vocal socioemotional expressions in adolescence

Ambiguity potentiates effects of loneliness on feelings of rejection

For social species, having strong and high-quality social relationships is an important safety cue. Loneliness occurs when an individual perceives they have insufficient relationships resulting in feelings of lack of safety. States of perceived unsafety are linked to an increased tendency to construe ambiguous information - information lacking a unique clear interpretation - as threatening. Here, we explore whether the ambiguity of social cues of interpersonal rejection moderates effects of loneliness on feelings of rejection while undergoing social exclusion. Data were collected in 2021; 144 adults completed a progressive social exclusion paradigm where they were randomly assigned to be equally included, excluded, or over-included. Social exclusion/inclusion cues became more pronounced over the course of multiple rounds of a ball-tossing game (Cyberball) resulting in a scenario where ambiguity was highest in earlier rounds and decreased over time. Participants reported feelings of loneliness prior to the task and feelings of rejection throughout the task. Results demonstrated that higher loneliness predicted increased feelings of rejection regardless of exclusion condition. Notably, this positive relationship was strongest during earlier rounds when social cues were most ambiguous. These findings contribute to our understanding of how loneliness modulates social perception to enable organisms to adequately adapt to changing circumstances.

The Association Between Emotion Recognition and Internalizing Problems in Children and Adolescents: A Three-Level Meta-Analysis

Numerous studies have explored the link between how well youth recognize emotions and their internalizing problems, but a consensus remains elusive. This study used a three-level meta-analysis model to quantitatively synthesize the findings of existing studies to assess the relationship. A moderation analysis was also conducted to explore the sources of research heterogeneity. Through a systematic literature search, a total of 42 studies with 201 effect sizes were retrieved for the current meta-analysis, and 7579 participants were included. Emotion recognition was negatively correlated with internalizing problems. Children and adolescents with weaker emotion recognition skills were more likely to have internalizing problems. In addition, this meta-analysis found that publication year had a significant moderating effect. The correlation between emotion recognition and internalizing problems decreased over time. The degree of internalizing problems was also found to be a significant moderator. The correlation between emotion recognition and internalizing disorders was higher than the correlation between emotion recognition and internalizing symptoms. Deficits in emotion recognition might be relevant for the development and/or maintenance of internalizing problems in children and adolescents. The overall effect was small and future research should explore the clinical relevance of the association.

Associations of emotion recognition, loneliness, and social functioning in euthymic patients with bipolar disorder

Emotion recognition deficit is related to impaired community functioning. Loneliness is also associated with impaired social performance. However, the way in which emotion recognition and loneliness may contribute to social functioning remains unclear in euthymic patients with bipolar disorder. We aimed to examine emotion recognition ability in Han Chinese euBD patients relative to healthy controls (HCs) and to investigate the associations between emotion recognition, loneliness, and social functioning. Thirty-nine HCs and 46 euthymic BD patients completed an emotion recognition task and nonsocial cognitive measures related to executive function and attention. The UCLA loneliness scale and Social Performance Scale were administered to evaluate psychological loneliness and social functioning, respectively. We observed lower emotion recognition accuracy, higher loneliness, and poorer social functioning in the BD patients after adjustment for demographic data. Loneliness was negatively associated with global social functioning in both the BD and HC groups. Higher loneliness and lower emotion recognition accuracy were associated with poorer social functioning in euthymic BD in different subdomains. Our study confirmed a subtle impairment of emotion recognition ability in euthymic BD. Loneliness impacts globally on social functioning, while emotion recognition ability may affect specific subdomains of social functioning in euthymic BD. Alleviation of loneliness and enhancement of social cognition might improve social functioning in BD patients.

Behavioral and Neural Dissociation of Social Anxiety and Loneliness

Loneliness is a public health concern with detrimental effects on physical and mental well-being. Given phenotypical overlaps between loneliness and social anxiety (SA), cognitive-behavioral interventions targeting SA might be adopted to reduce loneliness. However, whether SA and loneliness share the same underlying neurocognitive mechanisms is still an elusive question. The current study aimed at investigating to what extent known behavioral and neural correlates of social avoidance in SA are evident in loneliness. We used a prestratified approach involving 42 (21 females) participants with high loneliness (HL) and 40 (20 females) participants with low loneliness (LL) scores. During fMRI, participants completed a social gambling task to measure the subjective value of engaging in social situations and responses to social feedback. Univariate and multivariate analyses of behavioral and neural data replicated known task effects. However, although HL participants showed increased SA, loneliness was associated with a response pattern clearly distinct from SA. Specifically, contrary to expectations based on SA differences, Bayesian analyses revealed moderate evidence for equal subjective values of engaging in social situations and comparable amygdala responses to social decision-making and striatal responses to positive social feedback in both groups. Moreover, while explorative analyses revealed reduced pleasantness ratings, increased striatal activity, and decreased striatal-hippocampal connectivity in response to negative computer feedback in HL participants, these effects were diminished for negative social feedback. Our findings suggest that, unlike SA, loneliness is not associated with withdrawal from social interactions. Thus, established interventions for SA should be adjusted when targeting loneliness.SIGNIFICANCE STATEMENT Loneliness can cause serious health problems. Adapting well-established cognitive-behavioral therapies targeting social anxiety might be promising to reduce chronic loneliness given a close link between both constructs. However, a better understanding of behavioral and neurobiological factors associated with loneliness is needed to identify which specific mechanisms of social anxiety are shared by lonely individuals. We found that lonely individuals show a consistently distinct pattern of behavioral and neural responsiveness to social decision-making and social feedback compared with previous findings for social anxiety. Our results indicate that loneliness is associated with a biased emotional reactivity to negative events rather than social avoidance. Our findings thus emphasize the distinctiveness of loneliness from social anxiety and the need for adjusted psychotherapeutic protocols.

Choking under pressure: Does it get easier with age? How loneliness affects social monitoring across the life span

Previous experimental work showed that young adults reporting loneliness performed less well on emotion recognition tasks (Diagnostic Analysis of Nonverbal Accuracy [DANVA-2]) if they were framed as indicators of social aptitude, but not when the same tasks were framed as indexing academic aptitude. Such findings suggested that undergraduates reporting loneliness possessed the social monitoring skills necessary to read the emotions underlying others’ facial expressions, but that they choked under social pressure. It has also been found that undergraduates reporting loneliness have better recall for both positive and negative social information than their non-lonely counterparts. Whether those effects are evident across different age groups has not been examined. Using data from the British Broadcasting Corporation (BBC) Loneliness Experiment that included participants aged 16–99 years (N = 54,060), we (i) test for replication in a larger worldwide sample and (ii) extend those linear model analyses to other age groups. We found only effects for participants aged 25–34 years: In this age group, loneliness was associated with increased recall of negative individual information, and with choking under social pressure during the emotion recognition task; those effects were small. We did not find any such effects among participants in other age groups. Our findings suggest that different cognitive processes may be associated with loneliness in different age groups, highlighting the importance of life-course approaches in this area.

Increases in loneliness during medical school are associated with increases in individuals' likelihood of mislabeling emotions as negative

Expressions of emotion represent an important and unique source of information about the states of others. Being able to effectively understand expressions of emotions to make inferences about others' internal mental states and use these inferences to guide decision-making and behavior is critical to navigating social relationships. Loneliness, the perception that one lacks social connection, has important functional consequences for how individuals attend to signals of emotions in others. However, it is less clear whether loneliness changes how individuals recognize emotions in others. In medical practitioners, being able to accurately recognize emotional cues from patients is critical to effectively diagnosing and reacting with care to those patients. The current study examines the relationship between changes in loneliness during medical school and students' recognition of emotion in others. Measures of loneliness and emotion recognition were collected from 122 medical students during their first 3 years of medical school at the beginning and end of each academic year. Changes in loneliness were related to changes in emotion detection, with increases in loneliness being associated with decreases in the probability of accurately discriminating sad and angry faces from other expressions, decreases in the probability of mislabeling emotion expressions as happy, and increases in the probability of mislabeling other emotional expressions as pained and angry. This study suggests that changes in loneliness during medical school are associated with increases in students' labeling emotional expressions as negative, possibly by shifting attention to cues of negative emotion and away from cues of positive emotion.
