Transparent masks reduce the negative impact of opaque masks on understanding emotional states but not on sharing them

While face masks provide necessary protection against disease spread, they occlude the lower face parts (chin, mouth, nose) and consequently impair the ability to accurately perceive facial emotions. Here we examined how wearing face masks impacted making inferences about emotional states of others (i.e., affective theory of mind; Experiment 1) and sharing of emotions with others (i.e., affective empathy; Experiment 2). We also investigated whether wearing transparent masks ameliorated the occlusion impact of opaque masks. Participants viewed emotional faces presented within matching positive (happy), negative (sad), or neutral contexts. The faces wore opaque masks, transparent masks, or no masks. In Experiment 1, participants rated the protagonists’ emotional valence and intensity. In Experiment 2, they indicated their empathy for the protagonist and the valence of their emotion. Wearing opaque masks impacted both affective theory of mind and affective empathy ratings. Compared to no masks, wearing opaque masks resulted in assumptions that the protagonist was feeling less intense and more neutral emotions. Wearing opaque masks also reduced positive empathy for the protagonist and resulted in more neutral shared valence ratings. Wearing transparent masks restored the affective theory of mind ratings but did not restore empathy ratings. Thus, wearing face masks impairs nonverbal social communication, with transparent masks able to restore some of the negative effects brought about by opaque masks. Implications for the theoretical understanding of socioemotional processing as well as for educational and professional settings are discussed.

I can see it in your eyes: Perceived gaze direction impacts ERP and behavioural measures of affective theory of mind

Looking at someone's eyes is thought to be important for affective theory of mind (aTOM), our ability to infer their emotional state. However, it is unknown whether an individual's gaze direction influences our aTOM judgements and what the time course of this influence might be. We presented participants with sentences describing individuals in positive, negative or neutral scenarios, followed by direct or averted gaze neutral face pictures of those individuals. Participants made aTOM judgements about each person's mental state, including their affective valence and arousal, and we investigated whether the face gaze direction impacted those judgements. Participants rated that gazers were feeling more positive when they displayed direct gaze as opposed to averted gaze, and that they were feeling more aroused during negative contexts when gaze was averted as opposed to direct. Event-related potentials associated with face perception and affective processing were examined using mass-univariate analyses to track the time-course of this eye-gaze and affective processing interaction at a neural level. Both positive and negative trials were differentiated from neutral trials at many stages of processing. This included the early N200 and EPN components, believed to reflect automatic emotion areas activation and attentional selection respectively. This also included the later P300 and LPP components, thought to reflect elaborative cognitive appraisal of emotional content. Critically, sentence valence and gaze direction interacted over these later components, which may reflect the incorporation of eye-gaze in the cognitive evaluation of another's emotional state. The results suggest that gaze perception directly impacts aTOM processes, and that altered eye-gaze processing in clinical populations may contribute to associated aTOM impairments.

The mediating effect of language on the development of cognitive and affective theory of mind

Theory of mind (ToM) development is critical to effective social functioning and appears to depend on complementary language abilities. The current study explored the mediating influence of language on the development of both cognitive and affective ToM. A total of 151 children aged 5-12 years completed ToM (cognitive and affective) and language assessments, and parents provided ratings of their children's empathic ability. Results showed that language mediated the relationship between age and both cognitive and affective ToM but not parent-reported cognitive empathy. Examination of younger and older subgroups revealed that language mediated cognitive and affective ToM differently across developmental periods. Findings highlight the dynamic role that language plays in the development of both cognitive and affective ToM throughout early and middle childhood.

Empathy and Theory of Mind in Alzheimer's Disease: A Meta-analysis

OBJECTIVE

A large literature now shows that Alzheimer's disease (AD) disrupts a number of social cognitive abilities, including social perceptual function and theory of mind (ToM). However, less well understood is how the specific subcomponents of ToM as well as both the broader and specific subcomponents of empathic processing are affected.

METHOD

The current study provides the first meta-analytic review of AD that focuses on both empathy and ToM as broad constructs, as well as their overlapping (cognitive empathy and affective ToM) and distinct (affective empathy and cognitive ToM) subcomponents.

RESULTS

Aggregated across 31 studies, the results revealed that, relative to controls, AD is associated with large-sized deficits in both cognitive ToM (g = 1.09) and affective ToM/cognitive empathy (g = 0.76). However, no statistical differences were found between the AD participants and controls on affective empathic abilities (g = 0.36).

CONCLUSIONS

These data point to a potentially important disconnect between core aspects of social cognitive processing in people with AD. The practical and theoretical implications of these findings are discussed.

Subclinical maternal depressive symptoms modulate right inferior frontal response to inferring affective mental states of adults but not of infants

BACKGROUND

Being a mother of young children increases the risk of depression characterised by deficits in inferring what a person is feeling, i.e., affective theory of mind (aToM). Despite the adverse consequences for mothers, children, families, and society as a whole, little is known of how the brain functions underlying aToM ability are affected by subclinical maternal depressive symptoms, and act as a risk indicator for major depressive disorders (MDD).

METHODS

Thirty healthy mothers with varying levels of depressive symptoms underwent functional magnetic resonance imaging (fMRI) while performing mind-reading tasks based on the emotional expressions of adult eyes and infant faces.

RESULTS

In the adult eyes-based mind-reading task, mothers with more severe depressive symptoms showed less activation in the right inferior frontal gyrus (IFG), a central part of the putative mirror neuron system (pMNS). This was unrelated to behavioural performance decline in the task. However, brain activation involved in the infant face-based mind-reading task was not affected by depressive symptoms.

LIMITATIONS

Although aToM ability, assessed by mind-reading tasks, can be distinguished from empathy, these can be interacting functions of the pMNS, wherein they could mutually affect each other.

CONCLUSION

These findings suggest that functional activation of the right IFG, which underlies aToM ability, has variable vulnerability to maternal depressive symptoms according to the type of social signal. This functional decline of the right IFG may be a risk indicator for clinical maternal depression, which is associated with impaired social functioning and communication conflicts with family members and other social supporters.

Auditory top-down control and affective theory of mind in schizophrenia with and without hallucinations

Social cognitive impairments may represent a core feature of schizophrenia and above all are a strong predictor of positive psychotic symptoms. Previous studies could show that reduced inhibitory top-down control contributes to deficits in theory of mind abilities and is involved in the genesis of hallucinations. The current study aimed to investigate the relationship between auditory inhibition, affective theory of mind and the experience of hallucinations in patients with schizophrenia. In the present study, 20 in-patients with schizophrenia and 20 healthy controls completed a social cognition task (the Reading the Mind in the Eyes Test) and an inhibitory top-down Dichotic Listening Test. Schizophrenia patients with greater severity of hallucinations showed impaired affective theory of mind as well as impaired inhibitory top-down control. More dysfunctional top-down inhibition was associated with poorer affective theory of mind performance, and seemed to mediate the association between impairment to affective theory of mind and severity of hallucinations. The findings support the idea of impaired theory of mind as a trait marker of schizophrenia. In addition, dysfunctional top-down inhibition may give rise to hallucinations and may further impair affective theory of mind skills in schizophrenia.

Emergence of hyper empathy after right amygdalohippocampectomy

We report a fascinating case of a patient with a hyper empathy that appeared after resective epilepsy surgery. This behavioral modification has remained unchanged since the surgery took place 13 years ago. Recent neuropsychological objective assessments confirmed hyper empathy in a self-report questionnaire, and revealed higher affective theory of mind than controls in a "Reading the Mind in the Eyes Task." Temporal lobe epilepsy is the most common form of epilepsy and the investigation of emotional processes after surgery in these patients deserves to be related.
