Background
Research has demonstrated a strong relationship between autism and gender dysphoria (GD) and that this relationship could be explained by obsessional interests which are characteristic of autism. However, these studies often measured obsessions using either single items which questions the reliability of the findings, or within autistic...
Inter‐brain synchrony occurs between individuals who feel connected socially, but how synchrony relates to felt connectedness under naturalistic social interaction has remained enigmatic. We hypothesized that inter‐brain synchrony between naturally interacting individuals might be associated with the internalization of a social identity, a link bet...
This systematic review investigated how studies have measured gender dysphoria (GD) in autistic samples and the impact of using different measures on study results. The literature search identified 339 relevant papers, with 12 of them meeting the inclusion criteria. Results showed that seven different measures of GD characteristics have been used w...
The Autism-Spectrum Quotient (AQ) measures the degree of autistic traits in clinical and non-clinical samples and has been validated in various countries and languages. However, the AQ has not been validated in Singapore, an Asian country whose population speaks predominantly English. Although previous validation studies have examined the distribut...
The Dual Process Theory of Autism proposes that autistic individuals demonstrate greater deliberative (slower) processing alongside reduced (faster) intuitive processing. This study manipulated the reasoning time available to investigate the extent to which deliberative and intuitive processing are sensitive to time context in autism. A total of 74...
Unlabelled:
Research has shown that high trait anxiety can alter multisensory processing of threat cues (by amplifying integration of angry faces and voices); however, it remains unknown whether differences in multisensory processing play a role in the psychological response to trauma. This study examined the relationship between multisensory emot...
Empathy involves both empathic ability and empathic motivation. An important topic has been how to measure empathic ability and motivation simultaneously in both clinical and non-clinical samples and across different cultures. The Empathy Components Questionnaire (ECQ) is a self-report questionnaire that measures empathic ability and motivation in...
Music involves different senses and is emotional in nature, and musicians show enhanced detection of audio-visual temporal discrepancies and emotion recognition compared to non-musicians. However, whether musical training produces these enhanced abilities or if they are innate within musicians remains unclear. Thirty-one adult participants were ran...
Art appreciation reflects an initial emotional and intuitive response to artwork evaluation, although this intuitive evaluation can be attenuated by subsequent deliberation. The Dual Process Theory of Autism proposes that individuals with Autism Spectrum Disorder (ASD) have a greater propensity to deliberate and reduced intuition compared to matche...
Background
Restricted and repetitive behaviours (RRBs) are a core diagnostic feature in autism, but have received less research compared to other diagnostic areas. Qualitative research with autistic adults has reported both positive and problematic aspects of RRBs, but little qualitative research has been reported to date about the nature and outco...
A goal of brain-computer-interface (BCI) research is to accurately classify participants' emotional status via objective measurements. While there has been a growth in EEG-BCI literature tackling this issue, there exist methodological limitations that undermines its ability to reach conclusions. These include both the nature of the stimuli used to...
Background:
Emotion perception is essential to human interaction and relies on effective integration of emotional cues across sensory modalities. Despite initial evidence for anxiety-related biases in multisensory processing of emotional information, there is no research to date that directly addresses whether the mechanism of multisensory integra...
In everyday life, information from multiple senses is integrated for a holistic understanding of emotion. Despite evidence of atypical multisensory perception in populations with socio-emotional difficulties (e.g., autistic individuals), little research to date has examined how anxiety impacts on multisensory emotion perception. Here we examined wh...
Autism spectrum disorder (ASD) is associated with atypical autonomic nervous system (ANS) function. However, little is known about this relationship, while accounting for co-occurring mental health conditions (e.g. anxiety) that are also associated with ANS dysfunction. In addition, research on the ANS has typically involved physiological measureme...
This is the first longitudinal study to quantitatively evaluate changes in social network structure (SNS) and perceived social support (PSS) amongst first-year students on the autism spectrum (n = 21) and typically developing (TD; n = 182) students transitioning to university. The relative impact of changes in SNS/PSS, students’ social anxiety and...
Applying to university can be an anxiety-provoking time for many autistic students, though enrolment can be increased by actively involving them in transition planning. We provide an evaluation of a transition to university pilot programme (Autism Summer School) for autistic students (16–19 years) who are seeking to apply/attend university. The con...
Transitioning to university can be anxiety-provoking for all students. The relationship between social anxiety, autistic traits and students’ social network structure, and perceived support is poorly understood. This study used a group-matched design where autistic students (n = 28) and typically developing students (n = 28) were matched on sex, ag...
Covert facial mimicry involves subtle facial muscle activation in observers when they perceive the facial emotional expressions of others. It remains uncertain whether prototypical facial features in emotional expressions are being covertly mimicked and also whether covert facial mimicry involves distinct facial muscle activation patterns across mu...
Background:
Previous research using the Sensory Perception Quotient (SPQ) has reported greater sensory hypersensitivity in people with autism spectrum condition (ASC) compared to controls, consistent with other research. However, current scoring of the SPQ does not differentiate between hyper and hyposensitivity, making it uncertain whether indivi...
The academic, daily-living, and social challenges all students face during university transition can become magnified for many autistic students, who might struggle to adapt to changes in their social network structure (SNS) and perceived social support (PSS). This study assessed the development, feasibility, and convergent validity of a novel onli...
University provides individuals with the opportunity to develop greater independence in living skills and social networks, while also gaining valuable qualifications. Despite a high proportion of autistic individuals aspiring to attend university, many either do not seek or gain entry or drop out prematurely. Although some steps have been taken to...
Recent theories of autism have emphasised the cognitive strengths and weaknesses in those with autism, which are also seen to some degree in non-clinical samples with higher autistic-like traits. The dual process theory of autism proposes that people with autism and non-clinical people with a higher degree of autistic-like traits have a propensity...
Background:
Developmental coordination disorder (DCD), also known as dyspraxia, is a disorder emerging in childhood characterised by motor skill impairments. The motor difficulties often produce negative effects in other areas of life, such as poor self-esteem and reduced social interactions. One treatment used for DCD is fascia Bowen therapy, whi...
According to embodied cognition accounts, viewing others’ facial emotion can elicit the respective emotion representation in observers which entails simulations of sensory, motor, and contextual experiences. In line with that, published research found viewing others’ facial emotion to elicit automatic matched facial muscle activation, which was fur...

People often fail to detect large changes to visual scenes following a brief interruption, an effect known as ‘change blindness’. People with autism spectrum conditions (ASC) have superior attention to detail and better discrimination of targets, and often notice small details that are missed by others. Together these predict people with autism sho...
There has been much research on sex differences in the ability to recognise facial expressions of emotions, with results generally showing a female advantage in reading emotional expressions from the face. However, most of the research to date has used static images and/or ‘extreme’ examples of facial expressions. Therefore, little is known about h...

Comparison of the diagnostic validity of the ADOS (G) and 3Di in diagnosing girls and boys suspected of having ASD. Poster presented at INSAR 2017.
Dual Process Theory has recently been applied to Autism spectrum disorder (ASD) to suggest that reasoning by people with ASD and people with higher levels of ASD-like traits can be characterised by reduced intuitive and greater reflective processing. 26 adolescents and adults with ASD and 22 adolescent and adult controls completed an assessment of...
Key research suggests that empathy is a multidimensional construct comprising of both cognitive and affective components. More recent theories and research suggest even further factors within these components of empathy, including the ability to empathize with others versus the drive towards empathizing with others. While numerous self-report measu...

Background
A plethora of research on facial emotion recognition in autism spectrum disorders (ASD) exists and reported deficits in ASD compared to controls, particularly for negative basic emotions. However, these studies have largely used static high intensity stimuli. The current study investigated facial emotion recognition across three levels o...
Dual process theory proposes two distinct reasoning processes in humans, an intuitive style that is rapid and automatic and a deliberative style that is more effortful. However, no study to date has specifically examined these reasoning styles in relation to the autism spectrum. The present studies investigated deliberative and intuitive reasoning...
We are constantly forming impressions about those around us. Social interaction depends on our understanding of interpersonal behavior - assessing one another's personality, emotions, thoughts and feelings, attitudes, deceptiveness, group memberships, and other personal characteristics through facial expressions, body language, voice and spoken lan...
Most of the existing sets of facial expressions of emotion contain static photographs. While increasing demand for stimuli with enhanced ecological validity in facial emotion recognition research has led to the development of video stimuli, these typically involve full-blown (apex) expressions. However, variations of intensity in emotional facial e...

Individuals with ASD showed an impairment in facial emotion recognition across intensity levels based on both, difficulties in detecting emotional content from faces and discriminating between emotions from faces.
Background: Transition to University can provide opportunities to develop greater independence in living skills and social networks as well as gain valuable educational qualifications. University transition may present particular challenges for students with a diagnosis of an Autism Spectrum Disorder (ASD). Studies report students with ASD often do...
Attention Bias Modification (ABM) targets attention bias (AB) towards threat and is a potential therapeutic intervention for anxiety. The current study investigated whether initial AB (towards or away from spider images) influenced the effectiveness of ABM in spider fear.
AB was assessed with an attentional probe task consisting of spider and neutr...
Abstract: Facial emotion recognition from videos with varying intensity in autism
Background: Autism Spectrum Disorders (ASD) are defined by impairments in social communication and interaction, including non-verbal communication such as emotional expressions. However, behavioural studies comparing ASD to controls on facial emotion recognition have...
Gaze direction provides important information about social attention, and people tend to reflexively orient in the direction others are gazing. Perceiving the gaze of others relies on the integration of multiple social cues, which include perceptual information related to the eyes, gaze direction, head position, and body orientation of others. Auti...
Researchers have suggested that the two primary cognitive features of autism spectrum disorder (ASD), a drive toward nonsocial processing and a reduced drive toward social processing, may be unrelated to each other in the neurotypical (NT) population and may therefore require separate explanations. Drive toward types of processing may be related to...
People with autism spectrum conditions (ASC) report heightened olfaction. Previous sensory experiments in people with ASC have reported hypersensitivity across visual, tactile, and auditory domains, but not olfaction. The aims of the present study were to investigate olfactory sensitivity in ASC, and to test the association of sensitivity to autist...
Background:
Non-social behaviours, such as repetitive actions and restricted interests, form one of the crucial diagnostic criteria for Autism Spectrum Disorders (ASDs). The Extreme Male Brain (EMB) theory of autism suggests that these characteristics reflect an exaggeration of typically male cognitive function, in particular a drive towards rule-b...
Summary This chapter has reviewed both the early mindblindness theory of autism, and the more recent extensions of these: the empathizing-systemizing theory, and the extreme male brain theory, of autism. The first of these extensions addresses a problem that the early ...
People with autism spectrum disorders (ASD) often take longer to make decisions. The Autism-Psychosis Model proposes that people with autism and psychosis show the opposite pattern of results on cognitive tasks. As those with psychosis show a jump-to-conclusions reasoning bias, those with ASD should show a circumspect reasoning bias. Jumping-to-con...
Background: Autism Spectrum Conditions (ASC) are characterized by social and communication difficulties. These include abnormalities in gaze perception and in theory of mind (ToM), including reading other’s mental states from their eyes. There have been mixed findings in various tasks of gaze processing to date, with some showing intact ability in...
Social and communicative deficits, restricted interests and repetitive behaviors are diagnostic features of autism spectrum disorders (ASD). The present study examined the relationship between autistic characteristics and schizophrenia-spectrum traits as well as between autistic characteristics and obsessive-compulsive traits in typically developed...
People are typically faster and more accurate to detect angry compared to happy faces, which is known as the anger superiority effect. Many cognitive models of anxiety suggest anxiety disorders involve attentional biases towards threat, although the nature of these biases remains unclear. The present study used a Face-in-the-Crowd task to investiga...
Background: Females generally perform better than males on some measures of social processing (e.g. Empathizing), while males typically perform better than females on some measures of non-social processing (e.g. Systemizing). Extremes of these sex-typical cognitive profiles are associated with the development and maintenance of certain psychiatric...
The impact of trait anxiety and perceptual load on selective attention was examined in a fear conditioning paradigm. A fear-conditioned angry face (CS+), an unconditioned angry face (CS-), or an unconditioned face with a neutral or happy expression were used in distractor interference and attentional probe tasks. In Experiments 1 and 2, participant...
We explore why people with autism spectrum conditions (ASC) not only show deficits but also areas of intact or even superior skill. The deficits are primarily social; the areas of intact or superior skill involve attention to detail and systemizing. Systemizing is the drive to analyse or build a system. We review the evidence related to systemizing...
This study examined the impact of perceptual load on the processing of unattended threat-relevant faces. Participants performed a central letter-classification task while ignoring irrelevant face distractors, which appeared above or below the central task. The face distractors were graded for affective salience by means of aversive fear conditionin...
The empathising–systemising (E–S) theory proposes that many sex differences can be explained by females typically demonstrating greater empathising abilities (understanding of the social world) and males typically demonstrating greater systemising abilities (understanding of the non-social world). Autism is argued to represent an ‘Extreme Male Brai...
Background: Autism spectrum conditions (ASC) are characterized by social and communicative difficulties alongside repetitive and restricted behavior. Some have proposed that social information is less salient than in typical controls. In line with this, people with ASC look less at faces and are less likely to use social information for inferring m...
This experiment compares the effects of visual vs. auditory presentation of cognitive bias modification (CBM) training scenarios upon interpretation style and emotional vulnerability. For both modalities, negative, but not positive interpretation biases were successfully induced relative to a baseline. Mood declined for the auditory but not the vis...
This paper investigates whether changes in mood state are an important component of cognitive bias modification (CBM) procedures. In a novel CBM procedure participants read either positive or negative statements relating to social issues for 5 min. Interpretation bias was measured by means of a scrambled sentence test, which was presented both befo...
Identification of facial emotions has been found to be impaired in schizophrenia but there are uncertainties about the neuropsychological specificity of the finding.
Twenty-two patients with schizophrenia and 20 healthy controls were given tests requiring identification of facial emotion, judgement of the intensity of emotional expressions without...
Background: Autism spectrum conditions (ASC) are neurodevelopmental conditions diagnosed on the basis of difficulties with social interaction and communication, alongside overly narrow interests and repetitive behaviour. The first reports of autism and Asperger's Syndrome noted that people with these conditions commonly show atypical perceptual pro...
We argue that hyper-systemizing predisposes individuals to show talent, and review evidence that hyper-systemizing is part of the cognitive style of people with autism spectrum conditions (ASC). We then clarify the hyper-systemizing theory, contrasting it to the weak central coherence (WCC) and executive dysfunction (ED) theories. The ED theory has...
Background: Anecdotal reports suggest sensory differences in autism spectrum conditions (ASC). In addition, studies using questionnaires such as the Sensory Profile have revealed sensory abnormalities in over 90% of children with ASC.
Objectives: This study explores sensory sensitivity using detection tasks in both touch and hearing in female and...
Humans differ in terms of biased attention for emotional stimuli and these biases can confer differential resilience and vulnerability to emotional disorders. Selective processing of positive emotional information, for example, is associated with enhanced sociability and well-being while a bias for negative material is associated with neuroticism a...
Description of genotyping methodology
Anecdotal accounts of sensory hypersensitivity in individuals with autism spectrum conditions (ASC) have been noted since the first reports of the condition. Over time, empirical evidence has supported the notion that those with ASC have superior visual abilities compared with control subjects. However, it remains unclear whether these abilities ar...
Eyes are key social features providing a wealth of information about the attention, interest, emotion, and intention of others. Humans are typically very adept at detecting gaze direction, but there is a large decrement in gaze discrimination ability when eye images change from positive to negative polarity. This is thought to show an expert system...
This study investigates the development of children's understanding of others' intentions. We report 3 experiments in which three-and five-year-olds (total sample: N = 120) were tested using 15 videotaped pairs of action sequences excluding social information from the face. In each pair of videos the same action was performed with and without an in...
Sex differences exist in empathizing (females showing a stronger drive than males), and this contrasts with sex differences in systemizing (males showing a stronger drive). Systemizing occurs when one analyses or constructs a system according to rules that govern that system. In this chapter we re-analyse data from the Empathy Quotient (EQ) and Sys...
Impaired social cognition is a core feature of autism. There is much evidence showing people with autism use a different cognitive style than controls for face-processing. We tested if people with autism would show differential activation of social brain areas during a face-processing task. Thirteen adults with high-functioning autism or Asperger S...
Extreme conditions like savantism, autism or synaesthesia, which have a neurological 2AH, UK basis, challenge the idea that other minds are similar to our own. In this paper we report a single case study of a man in whom all three of these conditions co-occur. We suggest, on the basis of this single case, that when savantism and synaesthesia co- oc...
Autism and Asperger Syndrome are autism spectrum conditions (ASC) characterized by deficits in understanding others' minds, an aspect of which involves recognizing emotional expressions. This is thought to be related to atypical function and structure of the amygdala, and performance by people with ASC on emotion recognition tasks resembles that se...
Emotional Stroop tasks have shown attention biases of clinical populations towards stimuli related to their condition. Asperger Syndrome (AS) is a neuropsychiatric condition with social and communication deficits, repetitive behaviours and narrow interests. Social deficits are particularly striking, including difficulties in understanding others.
W...
Social threat captures attention and is processed rapidly and efficiently, with many lines of research showing involvement of the amygdala. Visual search paradigms looking at social threat have shown angry faces 'pop-out' in a crowd, compared to happy faces. Autism and Asperger Syndrome (AS) are neurodevelopmental conditions characterised by social...
Autism involves impairments in communication and social interaction, as well as high levels of repetitive, stereotypic, and ritualistic behaviours, and extreme resistance to change. This latter dimension, whilst required for a diagnosis, has received less research attention. We hypothesise that this extreme resistance to change in autism is rooted...
Autistic spectrum disorders (ASD) are neurodevelopmental conditions that may be caused by abnormal connectivity between brain regions constituting neurocognitive networks for specific aspects of social cognition.
We used three-way multidimensional scaling of regionally parcellated functional magnetic resonance imaging (fMRI) data to explore the hyp...
People show a left visual field (LVF) bias for faces, i.e., involving the right hemisphere of the brain. Lesion and neuroimaging studies confirm the importance of the right-hemisphere and suggest separable neural pathways for processing facial identity vs. emotions. We investigated the hemispheric processing of faces in adults with and without Aspe...
