When researchers write down their plans for a study ahead of time and make this public, this is called pre-registration. Pre-registration allows others to see if the researchers stuck to their original plan or changed as they went along. Pre-registration is growing in popularity but we do not know how widely it is used in autism research.

However, there is a lack of scholarship concerning the neurodevelopmental condition of Developmental Language Disorder (DLD) and the neurodiversity movement. While this movement may hold opportunities for the DLD community, the application of the concept of neurodiversity to DLD research and practice needs consideration, as DLD and autism have very different levels of public and professional awareness and understanding.

Students' experiences of stigma from staff and peers, and the masking behaviors they deploy to minimize it, can also result in worsening mental health. Despite these concerns, there is a lack of tailored support for autistic students at university.

But recent work has challenged this assumption by showing that suppression can be reweighted based on recent history; when pairs of stimuli are repeatedly presented together, suppression between them strengthens. Here we investigate the temporal dynamics of this process using a steady-state visual evoked potential (SSVEP) paradigm that provides a time-resolved, direct index of suppression between pairs of stimuli flickering at different frequencies (5 and 7 Hz).

While researched in autism, camouflaging has received no systematic study in other conditions affecting communication, including developmental language disorder (DLD). This study explored camouflaging in DLD, drawing on the experience and expertise of speech and language pathologists and parents of children with DLD.

Methods: We explored autistic women's experiences of coming to recognize and understand themselves as autistic. We used data collected from blogs written by autistic women about their diagnostic or self-identification experiences.

Objective: There has been suggestion that current diagnostic instruments are not sufficient for detecting and diagnosing autism in women, and research suggests that a lack of diagnosis could negatively impact autistic women's well-being and identity. This study aimed to explore the well-being and identity of autistic women at three points of their diagnostic journey: self-identifying or awaiting assessment, currently undergoing assessment or recently diagnosed, and more than a year post-diagnosis.
Methods: Mixed-methods were used to explore this with 96 women who identified as autistic and within one of these three groups.
Background And Aims: A high rate of children in mental health services have poor language skills, but little evidence exists on how mental health support is delivered to and received by children with language needs. This study looked at parental experiences, asking parents of children with speech, language and communication needs (SLCN) about their experiences seeking help for their children's mental health. We were particularly interested on the experiences of parents of children with Developmental Language Disorder (DLD), a specific SLCN that remains relatively unknown to the general public.
View Article and Find Full Text PDFBackground: While the relationship between speech, language and communication needs (SLCN) and mental health difficulties has been recognized, speech and language therapists (SLTs), and mental health professionals face challenges in assessing and treating children with these co-occurring needs. There exists a gap in the evidence base for best practice for professionals working with children and young people (CYP) who experience difficulties in both areas.
Aims: To explore the views of SLTs and mental health clinicians about their experiences of working with CYP exhibiting co-occurring SLCN and mental health difficulties.

Alexithymia, including 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 psychiatric conditions. The language hypothesis of alexithymia posits a language-mediated disruption in the development of discrete emotion concepts from ambiguous affective states, exacerbating the risk of developing alexithymia in language-impaired individuals. To provide a critical evaluation, a systematic review and meta-analysis of 29 empirical studies of language functioning in alexithymia was performed.

View Article and Find Full Text PDFMost theories of emotion describe a crucial role for interoceptive accuracy, the perception of the body's internal physiological signals, in emotional experience. Despite support for interoceptive accuracy's role in emotion, findings of gender differences in emotional and interoceptive processing are incompatible with theory; women typically show poorer interoceptive accuracy, but women often outperform men on measures of emotional processing and recognition. This suggests a need to re-evaluate the relationship between interoceptive accuracy and emotion considering sex and gender.

Accurate measures of alexithymia, an inability to recognise and describe one's own emotions, that are suitable for children are crucial for research into alexithymia's development. However, previous research suggests that parent versus child reports of alexithymia do not correlate. Potentially, children may report on the awareness of their emotions, whereas parent-report measures may reflect children's verbal expression of emotion, which may be confounded by children's communicative abilities, especially in conditions such as Developmental Language Disorder (DLD).
View Article and Find Full Text PDFDespite the heterogeneity in autism, socioemotional difficulties are often framed as universal. Increasing evidence, however, suggests that 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 may itself be a symptom of autism.

Despite its use to validate interoceptive measures and to assess interoceptive functioning in clinical groups, the empirical evidence for a relationship between HEP amplitude and interoceptive processing, including measures of such processing, is scattered across several studies with varied designs. The aim of this systematic review and meta-analysis was to examine the body of HEP-interoception research, and consider the associations the HEP shows with various direct and indirect measures of interoception, and how it is affected by manipulations of interoceptive processing.

It has therefore been proposed that problems within this system could explain the social difficulties experienced by people with autism spectrum condition. This idea is referred to as the broken mirror hypothesis.

Neuropsychological evidence is needed to investigate the possibility that acquired language problems could underlie acquired alexithymia.
Method: This project examined data from a large group of chronic stroke patients ( = 118) to test whether self-reported or behavioral measures of language and communication problems were associated with alexithymia.
Interoception, the perception of one's internal state, is commonly quantified using the heartbeat counting task (HCT) - which is thought to be a measure of cardiac interoceptive sensitivity (accuracy). Interoceptive sensitivity has been associated with a number of clinical traits and aspects of higher order cognition, including emotion processing and decision-making. It has been proposed that alexithymia (difficulties identifying and describing one's own emotions) is associated with impaired interoceptive sensitivity, but new research questions this association.
