Despite increasing empirical and theoretical work on empathy, particularly on the content of empathic representations, there is a relative lack of consensus regarding the information processing necessary for empathy to occur. Here we attempt to delineate a mechanistic cognitive model of empathy in order to provide a framework within which neuroimag...

In the director task (DT), participants are instructed to move objects within a grid of shelves while ignoring those objects that cannot be seen by a human figure, the "director," located beyond the shelves. It is widely assumed that, since they are explicitly instructed to do, participants use mentalizing in this communicative task; they represent...

It is widely accepted that autism is associated with disordered emotion processing and, in particular, with deficits of emotional reciprocity such as impaired emotion recognition and reduced empathy. However, a close examination of the literature reveals wide heterogeneity within the autistic population with respect to emotional competence. Here we...

Despite considerable research into whether face perception is impaired in autistic individuals, clear answers have proved elusive. In the present study, we sought to determine whether co-occurring alexithymia (characterized by difficulties interpreting emotional states) may be responsible for face-perception deficits previously attributed to autism...

Difficulties in social cognition are well recognized in individuals with autism spectrum conditions (henceforth 'autism'). Here we focus on one crucial aspect of social cognition: the ability to empathize with the feelings of another. In contrast to theory of mind, a capacity that has often been observed to be impaired in individuals with autism, m...

13 Most autistic adolescents experience anxiety. Interoception, defined as one's ability to detect 14 and interpret bodily signals, might contribute to this. The aim of this exploratory, qualitative 15 study was to gain a better understanding of interoceptive experiences in autistic adolescents 16 and how this relates to anxiety. Semi-structured 1:...

Alexithymia may explain the genetic relationship between 7 autism and sensory sensitivity Abstract 28 Sensory symptoms are highly prevalent amongst autistic individuals and are now considered 29 in the diagnostic criteria. Whilst evidence suggests a genetic relationship between autism and 30 sensory symptoms, sensory symptoms are neither universal...

The ability to represent and infer accurately others’ mental states, known as Theory of Mind (ToM), has been theorised to be associated with metacognitive ability. Here, we considered the role of metacognition in mental state inference through the lens of a recent theoretical approach to explaining ToM, the ‘Mind-space’ framework. The Mind-space fr...

With growing interest in interoceptive training to enhance the perception of internal bodily signals, there is a need to consider the mechanisms by which training may improve performance on tests of interoceptive accuracy (i.e., tests designed to measure how well signals from the body can be perceived). In this brief paper we use the example of car...

Individuals who are superior at face recognition are described as 'super recognisers' (SRs). On standard face recognition tasks SRs outperform individuals who have typical face recognition ability. However, high accuracy on face recognition tasks may be driven by superior ability in one or more of a number of component processes including face perc...

In recent years, there has been an increased interest in remote testing methods for quantifying individual differences in interoception, the perception of the body’s internal state. Hampering the adoption of remote methods are concerns as to the quality of data obtained remotely. Using data from several studies, we sought to compare the performance...

The theory of mind (ToM) hypothesis of autism is the idea that difficulties inferring the mental states of others may explain social communication difficulties in autism. In the present article, we critically evaluate existing theoretical accounts, concluding that none provides a sufficient explanation of ToM in autism. We then evaluate existing te...

Background: Adolescence is a developmental period during which an estimated 75% of mental health problems emerge (Solmi et al., 2022). This paper reports a feasibility study of a novel indicated, preventative, transdiagnostic, school-based intervention: Building Resilience Through Socioemotional Training (ReSET). The intervention addresses two doma...

In this Commentary article we expand on issues in the Theory of Mind literature raised by Wendt et al. (2024) that limit progress in our understanding of how people read other minds. We critically assess how they categorized tasks in their study, and in so doing raise deeper questions that need addressing: what exactly are mental states; how can we...

Societies are becoming more polarised, driven in part by misconceptions about out-groups’ beliefs. To understand these effects, one must examine the cognitive processes underlying how people think about others. Here, we investigate whether people are less prone to theorise about the minds of out-groups, or less able to do so. Participants (Study 1:...

Autistic youths tend to react negatively to uncertain events. Little is known about the cognitive processes associated with this intolerance of uncertainty, most notably the tendency to actively gather information to minimize uncertainty. Past research has relied on self-report measures that may not allow investigation of the multifaceted processes...

Theories of emotion ascribe a fundamental role to the processing of bodily signals (interoception) in emotional experience. Despite evidence consistent with this, current knowledge is limited by a focus on interoceptive accuracy and laboratory-based interoception measures. This experience-sampling study examines how state interoceptive attention an...

Alexithymia (difficulties identifying and describing feelings) predicts increased risks for psychopathology, especially during the transition from childhood to adolescence. However, little is known of the early contributors to alexithymia. The language hypothesis of alexithymia suggests that language deficits play a primary role in predisposing lan...

The terminology used in discussions on mental state attribution is extensive and lacks consistency. In the current paper, experts from various disciplines collaborate to introduce a shared set of concepts and make recommendations regarding future use.

Background Adolescence is a period of heightened vulnerability to developing mental health problems, and rates of mental health disorder in this age group have increased in the last decade. Preventing mental health problems developing before they become entrenched, particularly in adolescents who are at high risk, is an important research and clini...

Previous research suggests that the processing of internal body sensations (interoception) affects how we experience pain. Some evidence suggests that people with fibromyalgia syndrome (FMS) – a condition characterised by chronic pain and fatigue – may have altered interoceptive processing. However, extant findings are inconclusive, and some tasks...

Self-related processing is thought to be altered in autism, with several studies reporting that autistic individuals show a diminished neural response relative to neurotypicals for their own name and face. However, evidence remains scarce and is mostly based on event-related potential studies. Here, we used EEG to measure the neural activity of aut...

A recently published test of face perception, the Oxford Face Matching Test, asks participants to make two judgements: whether two faces are of the same individual; and how perceptually similar the two faces are. In the present study, we sought to determine to what extent the test can be shortened by removing the perceptual similarity judgements, a...

There are multiple psychological processes required in order for a face to be recognised from memory. However, when testing face memory using tasks such as the Cambridge Face Memory Task (CFMT), it is rare for studies to attempt to account for individual differences in face perception and face matching in order to isolate variance in face memory sp...

Autistic people report that their emotional expressions are sometimes misunderstood by non-autistic people. One explanation for these misunderstandings could be that the two neurotypes have different internal representations of emotion: Perhaps they have different expectations about what a facial expression showing a particular emotion looks like....

A central tenet of many theories of emotion is that emotional states are accompanied by distinct patterns of autonomic activity. However, experimental studies of coherence between subjective and autonomic responses during emotional states provide little evidence of coherence. Crucially, previous studies investigating coherence have either adopted u...

Every day we constantly observe other people receiving rewards. Theoretical accounts posit that vicarious reward processing might be linked to people's sensitivity to internal body states (interoception) and facilitates a tendency to act prosocially. However, the neural processes underlying the links between vicarious reward processing, interocepti...

Theory of mind (ToM), the ability to represent the mental states of oneself and others, is argued to be central to human social experience, and impairments in this ability are thought to underlie several psychiatric and developmental conditions. To examine the accuracy of mental state inferences, a novel ToM task was developed, requiring inferences...

Individuals with developmental prosopagnosia (DP) all exhibit impairments in face memory, but the specificity of these face memory impairments is debated. One problem is that standard behavioural tasks are not able to provide independent measurement of face perception, face memory, and face matching (the decision process required to judge whether t...

Unemployment and underemployment have consistently been shown to be higher in autistic adults relative to non-autistic adults. This may be due, in part, to a lack of workplace accommodations being made for autistic people. One factor that may contribute to employment inequalities in autistic people is differences in attitudes towards interpersonal...

Alexithymia, the inability to identify and express one's own feelings, is a subclinical condition responsible for some of the socioemotional symptoms seen across a range of psychopathological and neurodevelopmental conditions. The language hypothesis of alexithymia posits a language-mediated disruption in the development of discrete and categorical...

Previous studies have struggled to determine the relationship between mirror neuron brain regions and two distinct ‘action understanding’ processes: identifying actions, and identifying the intentions underlying those actions. This may be because the identification of intentions from others’ actions requires an initial action identification process...

Group membership is known to influence empathy – people empathise less, fail to empathise, or even take pleasure in outgroup suffering. One promising way to encourage empathy for outgroups involves portraying intergroup empathy as normative. However, people are often unaware of operative empathic norms, and must consequently rely on their subjectiv...

Anxiety is often conceptualised as the prototypical disorder of interoception (one’s perception of bodily states). Whilst theoretical models predict an association between interoceptive accuracy and anxiety, empirical work has produced mixed results. This manuscript presents a pre-registered systematic review (https://osf.io/2h5xz) and meta-analysi...

Despite the heterogeneity in autism, socioemotional difficulties are often framed as universal. Increasing evidence, however, suggests socioemotional difficulties may be explained by alexithymia, a distinct yet frequently co-occurring condition. If, as some propose, autistic traits are responsible for socioemotional impairments, then alexithymia ma...

Tasks measuring the sense of agency often manipulate the predictability of action outcomes by introducing spatial deviation. However, the extent to which spatial predictability of an outcome influences the sense of agency when spatial deviation is controlled for remains untested. We used a novel task to investigate the effect of several factors (ac...

According to predictive processing theories, emotional inference involves simultaneously minimising discrepancies between predictions and sensory evidence relating to both one's own and others' states, achievable by altering either one's own state (empathy) or perception of another's state (egocentric bias) so they are more congruent. We tested a k...

Theory of mind (ToM), the ability to represent the mental states of oneself and others, is argued to be central to human social experience, and impairments in this ability are thought to underlie several psychiatric and developmental conditions. Two ways in which individual differences in ToM might manifest are in the propensity to engage in mental...

Significant comorbidity has been demonstrated between feeding and eating disorders and autism. Atypical interoception (perception of bodily signals) may, at least in part, be responsible for this association, as it has been implicated in the aetiology of both conditions. However, significant methodological limitations are impeding progress in this...

Recognized as a simple communicative behavior, referential pointing is cognitively complex because it invites a communicator to consider an addressee's knowledge. Although we know referential pointing is affected by addressees’ physical location, it remains unclear whether and how communicators’ inferences about addressees’ mental representation of...

The ability to identify others’ actions and intentions, “action understanding”, is crucial for successful social interaction. Under direct accounts, action understanding takes place without the involvement of inferential processes, a claim that has yet to be tested using behavioural measures. Using a dual-task paradigm, the present study aimed to e...

The 'Attentional Blink' refers to difficulty in detecting the second of two target stimuli presented in rapid temporal succession. Studies have shown that salient target stimuli, such as one's own name, reduce the magnitude of this effect. Given indications that self-related processing is altered in autism, it is an open question whether this atten...

Theory of Mind (ToM), the ability to represent the mental states of oneself and others, is an essential social skill disrupted across many psychiatric conditions. The transdiagnostic nature of ToM impairment means it is plausible that ToM impairment is related to alexithymia (difficulties identifying and describing one’s own emotions), as alexithym...

Effects of ageing on both face perception and face memory have previously been reported. Previous studies, however, have not controlled for the effects of face perception when assessing face memory, meaning that apparent effects of ageing on face memory may actually be due to effects of ageing on face perception. Here, both face perception and face...

Interoception, perception of one's bodily state, has been associated with mental health and socio-emotional processes. However, several interoception tasks are of questionable validity, meaning associations between interoception and other variables require confirmation with new measures. Here we describe the novel, smartphone-based Phase Adjustment...

The inadequacy of a categorial approach to mental health diagnosis is now well-recognised, with many authors, diagnostic manuals and funding bodies advocating a dimensional, trans-diagnostic approach to mental health research. Variance in interoception, the ability to perceive one’s internal bodily state, is reported across diagnostic boundaries, a...

Interoception refers to the central nervous system's processing of internal physiological signals, such as heartrate and appetite signals (Khalsa et al., 2018). Fibromyalgia syndrome (FMS) is a disorder characterised by chronic widespread pain, in addition to fatigue, sleep disturbances, and autonomic disturbances (Sarzi-Puttini et al., 2020). Pre...

It has been argued that autistic individuals have difficulties with face memory but typical face perception. However, only one previous study has examined both face memory and face perception in the same individuals, and this study was conducted with a small group of autistic children.

Eye-tracking and recording of physiological signals are increasingly used in research within cognitive science and human-computer interaction. For example, gaze position and measures of autonomic arousal, including pupil dilation, skin conductance (SC) and heart rate (HR), provide an indicator of cognitive and physiological processes.

Objective Eating disorders are psychiatric illnesses characterized by extreme eating behaviors, such as sustained food restriction or loss of control over eating. Symptoms are thought to be maintained by a variety of mechanisms, one of which may be the socio-cognitive impairments associated with eating disorders. While some previous work has addres...

Tests of face processing are typically designed to identify individuals performing outside of the typical range; either prosopagnosic individuals who exhibit poor face processing ability, or super recognisers, who have superior face processing abilities.

A new task (‘CARER’) was used to test claims of reduced empathy in autistic adults. CARER measures emotion identification (ability to identify another’s affective state), affective empathy (degree to which another’s affective state causes a matching state in the Empathiser) and affect sharing (degree to which the Empathiser’s state matches the stat...
