Primary school children rate children with autism negatively on looks, speech and speech content
Adults and adolescents form negative first impressions of ASD adults and children. We examined the first impression ratings of primary school children (6–9 years) of their ASD peers. 146 school children rated either silent videos, speech or transcribe speech from 14 actors (7 ASD, 7 TD). The ASD actors were rated more negatively than the typically developing actors on all three stimulus types. Children with ASD are likely to be judged more negatively than their peers at the very start of their formal education. Contrary to previous research, for primary school children, the content of the speech was judged as negatively as the delivery of the speech.

Emotion Recognition and Context in Adolescents with Autism Spectrum Disorder
Emotion recognition research in autism has provided conflicting results and has ignored the role of context. We examined if autistic adolescents use context to identify displayed and felt emotion. Twenty adolescents with autism and 20 age-matched neurotypical adolescents identified emotions from a standardised set of images. The groups also viewed videos scenes with actors displaying a feigned emotion masking their true feelings. Participants identified the displayed and felt emotions. Both groups identified emotions from static images equally well. In the video condition, the autism group was unable to distinguish between the displayed and felt emotions. Emotion research is often divorced from context. Our findings suggest that autistic individuals have difficulty integrating contextual cues when processing emotions.

Autistic traits in individuals self-defining as transgender or nonbinary
Autism spectrum traits are increasingly being reported in individuals who identify as transgender, and the presence of such traits have implications for clinical support. To-date little is known about autism traits in individuals who identify as nonbinary. To empirically contribute to current research by examining autistic traits in a self-identifying transgender and nonbinary gender group. One hundred and seventy-seven participants responded to a survey consisting of the Autism Spectrum Quotient (AQ), the Empathy Quotient (EQ), the Systematising Quotient (SQ) and the Reading the Mind in the Eyes Task (RME). Comparisons were made between cisgender, transgender and nonbinary groups. Individuals with autism spectrum disorder (ASD) or meeting the AQ cut-off score for ASD were over-represented in both the transgender and nonbinary groups. The key variables differentiating the transgender and nonbinary groups from the cisgender group were systematising and empathy. Levels of autistic traits and cases of ASD were higher in individuals assigned female at birth than those assigned male at birth. A proportion of individuals seeking help and advice about gender identity will also present autistic traits and in some cases undiagnosed autism. Lower levels of empathy, diminished theory of mind ability and literalness may impede the delivery of effective support. Clinicians treating transgender and nonbinary individuals, should also consider whether clients, especially those assigned female at birth, have an undiagnosed ASD.

Altered bodily self-consciousness and peripersonal space in autism
There is some evidence that disordered self-processing in autism spectrum disorders is linked to the social impairments characteristic of the condition. To investigate whether bodily self-consciousness is altered in autism spectrum disorders as a result of multisensory processing differences, we tested responses to the full body illusion and measured peripersonal space in 22 adults with autism spectrum disorders and 29 neurotypical adults. In the full body illusion set-up, participants wore a head-mounted display showing a view of their ‘virtual body’ being stroked synchronously or asynchronously with respect to felt stroking on their back. After stroking, we measured the drift in perceived self-location and self-identification with the virtual body. To assess the peripersonal space boundary we employed an audiotactile reaction time task. The results showed that participants with autism spectrum disorders are markedly less susceptible to the full body illusion, not demonstrating the illusory self-identification and self-location drift. Strength of self-identification was negatively correlated with severity of autistic traits and contributed positively to empathy scores. The results also demonstrated a significantly smaller peripersonal space, with a sharper (steeper) boundary, in autism spectrum disorders participants. These results suggest that bodily self-consciousness is altered in participants with autism spectrum disorders due to differences in multisensory integration, and this may be linked to deficits in social functioning.

Living with autism without knowing: receiving a diagnosis in later life
Increasingly adults over the age of 50 are receiving a diagnosis of autism spectrum condition. Growing up in a time when autism was poorly recognised, these adults have lived unknowingly with the condition and face readjustment. This paper reports the first study to investigate this population. Nine adults over the age of 50, who had recently been diagnosed with ASC, were interviewed, and thematic analysis was used to analyse the transcripts. Results showed that the participants had received treatment for anxiety and depression. They reported ASC behaviours in their childhood and growing up they felt isolated and alien. Receiving a diagnosis was seen as a positive step and allowed for a reconfiguration of self and an appreciation of individual needs. Given the positive aspects of receiving a late diagnosis, more work is needed to identify older adults with undiagnosed ASC.

Transitional object use, attachment, and help‐seeking behaviour in Taiwanese adolescents
Transitional object use is psychologically beneficial for young children, but research has suggested that maintaining transitional object use into middle childhood may be associated with negative behaviour. Little is known about the continuation of transitional object use into adolescence, and few studies have been conducted with non‐Western populations. To examine differences in attachment and attitudes to help seeking in adolescents who did and did not use a transitional object, 723 adolescents from Taiwan (M age = 14 years) were asked about their current and past use of transitional objects. Measures of attachment were obtained using the Revised Adult Attachment Scale, and attitude toward help was measured using the Attitudes Toward Seeking Professional Psychological Help Scale. In total, 37% of the sample continued transitional object use in adolescence. Current use of a transitional object differentiated the sample on the measures of attachment and help seeking. Transitional object users were less likely to have secure attachments and less likely to express positive attitudes toward seeking help. Transitional object use is prevalent in Taiwanese adolescents, and we suggest that continued use of a transitional object acts as an indicator of potential withdrawal from support offered in schools.

The Feeling of Me Feeling for You: Interoception, Alexithymia and Empathy in Autism
Following recent evidence for a link between interoception, emotion and empathy, we investigated relationships between these factors in autism spectrum disorder (ASD). 26 adults with ASD and 26 healthy participants completed tasks measuring interoception, alexithymia and empathy. ASD participants with alexithymia demonstrated lower cognitive and affective empathy than ASD participants without alexithymia. ASD participants showed reduced interoceptive sensitivity (IS), and also reduced interoceptive awareness (IA). IA was correlated with empathy and alexithymia, but IS was related to neither. Alexithymia fulfilled a mediating role between IA and empathy. Our findings are suggestive of an alexithymic subgroup in ASD, with distinct interoceptive processing abilities, and have implications for diagnosis and interventions.
