Inner experiences, mental health, and well-being in autistic and non-autistic adults.

The nature of autistic adults' everyday inner experiences has been largely unstudied. The purpose of this study was to examine patterns of inner experiences and how they relate to mental health and wellness among autistic and non-autistic adults. Autistic (n = 303) and non-autistic (n = 289) adults (ages 21-82) completed online surveys assessing their anxiety, depression, happiness, life satisfaction, and inner thinking patterns, (inner speaking [i.e., verbal thinking], inner seeing [i.e., visual thinking], unsymbolized thinking, feelings, sensory awareness, self-talk). Group differences in inner thinking were examined using Mann-Whitney U and chi-square tests. Correlations and multiple linear regressions examined associations between inner experiences, mental health, and well-being. Autistic adults had greater use of inner speaking and sensory awareness, compared to non-autistic adults. The most common primary mode of inner experience for both groups was inner speaking, while fewer autistic adults reported that experiencing thoughts as feelings was their primary modality. Autistic adults reported greater use of self-talk for social assessment, self-criticism, and self-management purposes, compared to non-autistic adults. Experiencing thoughts as inner speech and as feelings were associated with anxiety in both groups. Using self-talk for social assessment and self-criticism purposes was correlated with anxiety and depression in both groups, while using self-talk for self-management was associated with depression and anxiety only among autistic adults. The results suggest that autistic and non-autistic adults have similarities in overall patterns of inner thinking, yet autistic adults may be more likely to engage in self-talk as a strategy to manage challenging day-to-day experiences.

The influence of body posture on facial expression perception in Autism.

Facial expression perception is influenced by body posture, with perception biased toward the body emotion. Previous research has suggested that the magnitude of this biasing influence of body posture is driven by individual differences in the precision of facial expression representations underlying discrimination abilities, where lower precision leads to a greater influence of body posture. It is unclear however whether similar mechanisms might drive the influence of contextual cues in Autism, which is often characterised by reduced facial expression discrimination abilities. Here, we addressed this question by using online psychophysical methods to determine the precision of isolated face and body expression representations of anger and disgust, and the influence of body on facial expression perception, in autistic and non-autistic adults. Both groups showed a strong influence of body context on facial expression perception, but this influence was larger in the autistic group, mirroring their lower overall precision of facial expression representations relative to non-autistic individuals. Crucially, the magnitude of the biasing influence of body posture in both groups was related to the precision of individuals' facial expression representations. The results suggest that similar principles govern the integration of facial expression and body posture information in both autistic and non-autistic individuals.

Evaluation of a Visual Cognitive Style in Autism: A Cluster Analysis.

Cognitive style refers to how individuals perceive their environment and solve problems. Among various cognitive styles documented, verbal and visual styles, including object versus spatial cognition, have been widely studied. "Thinking in pictures" is often associated with autism and characterized by enhanced performance and autonomy of certain perceptual areas. This study aimed to characterize the cognitive style of autistic individuals, focusing on this visual "thinking in pictures" style. We assessed 43 autistic and 42 non-autistic adults using the Object Spatial Imagery Verbal Questionnaire to evaluate three dimensions of their cognitive style: visual object, visual spatial, and verbal. Using a cluster analysis, we identified cognitive style profiles. We then examined manifestations of cognitive style within these profiles, including mental imagery abilities (with the Mental Rotation Test), the vividness of mental images (with the Vividness of Visual Imagery Questionnaire), language abilities (with the Mill Hill vocabulary test), and synesthetic experiences. Our results revealed three distinct cognitive profiles: a visual profile characterized by significant mental imagery and vivid mental images, a visuo-spatial profile associated with strong abilities to manipulate mental images but lower vividness of mental images, and a verbal profile with lower spatial imagery and manipulation abilities. While all profiles were observed in autistic individuals, the visual cognitive profile was the most common. Additionally, we found synesthesia to be more prevalent in the autistic population compared to the non-autistic population. This study confirms that, while not exclusive, a visual cognitive style is prevalent among autistic individuals.

The Chinese 10-Item Empathy Quotient and Systemising Quotient-Revised: Internal Consistency, Test-Retest Reliability, Known-Groups Validity, and Sex Differences in Autistic and Non-Autistic Adults.

The 10-item version of the Empathy Quotient (EQ-10) and the Systemising Quotient-Revised (SQ-R-10) were originally developed in the English-speaking population. However, little is known about the reliability of these measures. There is also extremely limited research translating or evaluating any translated version of these 10-item measures. The present study translated the measures into Chinese and evaluated the Chinese 10-item EQ (C-EQ-10) and SQ-R (C-SQ-R-10). An online survey consisting of the C-EQ-10 and the C-SQ-R-10 was completed by 698 non-autistic adults and 43 autistic adults in Hong Kong. Internal consistency of the measures was satisfactory in the autistic group (α = 0.60-0.63) and good in the non-autistic group (α = 0.76-0.82). Test-retest reliability was high in both the autistic group (r = .76-0.81) and the non-autistic group (r = .80-0.84). On average, the autistic group had significantly lower empathising than did the non-autistic group (Cohen's d = -1.21), and there was a trend of higher systemising in the autistic group than in the non-autistic group (Cohen's d = 0.20). On average, within the non-autistic group, males had significantly lower empathising (Cohen's d = -0.57) and significantly higher systemising (Cohen's d = 0.33) than did females. These average sex differences were attenuated and non-significant in the autistic group. Distribution patterns of "brain types" based on empathising-systemising difference scores seem to suggest that "brain types" are shifted towards systemising types in autistic or male participants. The C-EQ-10 and the C-SQ-R-10 are valid and reliable measures.

Processing of prosodic cues of uncertainty in autistic and non-autistic adults: a study based on articulatory speech synthesis.

We investigated the prosodic perception of uncertainty cues in adults with Autism Spectrum Disorder (ASD) compared to neurotypical adults (NTC). We used articulatory synthetic speech to express uncertainty in a human-machine scenario by varying the three acoustic cues pause, intonation, and hesitation. Twenty-eight adults with ASD and 28 NTC adults rated each answer for uncertainty, naturalness, and comprehensibility. Both groups reliably perceived different levels of uncertainty. Stimuli were rated as less uncertain by the ASD group, but not significantly. Only when we pooled the recipients' ratings for all three cues, did we find a significant group difference. In terms of reaction time, we observed longer reaction times in the ASD group compared to the neurotypical comparison group for the uncertainty level hesitation & strong intonation, but the differences were not significant after Bonferroni correction. Furthermore, our results showed a significant group difference between the correlation of uncertainty and naturalness, i.e. the correlation in the ASD group is significantly lower than in the NTC group. Obtained effect size estimates can inform sample size calculations in future studies for the reliable identification of group differences. In future work, we would like to further investigate the interaction of all three cues and uncertainty perception. It would be interesting to further vary the duration of the pause and also to use different types of fillers. From a developmental perspective, uncertainty perception should also be investigated in children and adolescents with ASD.

Autistic people differ from non-autistic people subjectively, but not objectively in their reasoning.

Autistic people often experience challenges in social contexts, and when decisions need to be made quickly. There is evidence showing that autistic people have a tendency for greater deliberation and lower intuition, compared to non-autistic people. This has led to the researchers' proposal that autism is associated with an enhanced level of rationality. However, these theories have been mostly explored through the lens of either only non-social domain or only social domain. To address this gap, we recruited autistic adults and carefully matched them with non-autistic adults for comparison. We used a task representing both social and non-social interactions in a comparison structure and asked participants' moral judgements on scenarios' main characters. This was complemented by subjective and objective measures of reasoning. Our findings did not reveal meaningful differences between groups in terms of deliberation. However, we did observe that autistic participants self-reported lower levels of intuition, compared to non-autistic participants. Autistic people consistently rate themselves as less intuitive than their counterparts. Nevertheless, objective evidence supporting this across tasks and studies is inconsistent.

Effects of predictability on visual and linguistic narrative comprehension in autistic and non-autistic adults

ABSTRACT Autistic individuals sometimes show differences from non-autistic individuals when understanding stories, regardless of whether those stories are told through words or pictures. In narrative comprehension, predicting upcoming words or events in a story may facilitate understanding. In studies measuring event-related potentials (ERPs) with non-autistic adults, more predictable words in a linguistic narrative or panels in a visual narrative typically elicit reduced N400 amplitudes compared to less predictable words/panels. However, the predictive processes used by autistic individuals may differ from those used by non-autistic individuals, which could contribute to differences in narrative comprehension. Here, we report two studies examining predictive processing in linguistic and visual narrative comprehension among autistic and non-autistic adults. Autistic adults showed earlier N400 modulations by cloze compared to non-autistic adults in both linguistic and visual modalities, which may reflect a more bottom-up processing style that relies less on active prediction of upcoming words or events.

Detecting criminal intent in social interactions: The influence of autism and theory of mind.

Defense attorneys sometimes suggest that social-cognitive difficulties render autistic individuals vulnerable to involvement in crime, often arguing that theory of mind (ToM) difficulties that undermine inferences about others' intentions underpin this vulnerability. We examined autistic adults' ability to respond adaptively to criminal intent during interactions and whether difficulties were associated with poor ToM. Compared with nonautistic adults, autistic adults were expected to be less likely to respond adaptively to another's criminal intent and less likely to do so early in interactions, with poorer performance associated with ToM difficulties. We developed the Suspicious Activity Paradigm, in which autistic (n = 102) and nonautistic (n = 95) adults listened (as if participating in an interaction) to audio scenarios in which cues suggesting their impending involvement in a crime gradually emerged. At periodic intervals, they were required to indicate how they would react toward the other person's behavior, with response coding reflecting detection of, and adaptive responding to, suspicious activity. We observed similar patterns of suspicion and adaptive responses in autistic and nonautistic adults as the scenarios progressed. Regardless of diagnostic status, pronounced ToM difficulties and low verbal ability were independently associated with a lower likelihood of reporting suspicion and responding adaptively. Our results do not support the perspective that autistic adults are uniquely vulnerable to crime involvement due to an inability to recognize and respond adaptively to suspicious behavior. The potential for heightened criminal vulnerability was associated with significant ToM difficulties (and verbal ability) regardless of autism diagnostic status, although such difficulties were more prevalent in the autistic sample. The finding that pronounced ToM difficulties may heighten criminal vulnerability for both autistic and nonautistic individuals challenges the validity of a generalized "autism" legal defense based on assumed rather than measured ToM difficulties.

The Moderating Effect of Sex on Autistic Trait Emotional Intelligence, Alexithymia, and Empathy.

Autism spectrum disorder (ASD) is associated with differences in social communication, and these differences are related to trait emotional intelligence (TEI), alexithymia, and empathy. Autism is known to present differently in males and females, but research on sex differences in TEI, alexithymia, and empathy is largely relegated to non-autistic people. Therefore, the current research sought to explore individual relationships between autistic characteristics and TEI, alexithymia, and empathy, as well as the possible influence of sex in these relationships. In the current study, autistic and non-autistic adults reported on their autistic characteristics, TEI, alexithymia, and empathy. Based on previous research, it was hypothesized that more autistic characteristics would be associated with less TEI, more alexithymia, and less empathy, and that these relationships would be more prominent amongst males. More autistic characteristics were associated with greater challenges across the three areas of interest. However, only the relationship between TEI and autistic characteristics was moderated by sex, such that males demonstrated higher support needs related to TEI than females. Results from this analysis indicate that adults with more autistic characteristics, regardless of diagnostic status, demonstrate differences in TEI, alexithymia, and empathy. The current analysis may offer additional context to the evolving understanding of empathy and autism by suggesting that TEI and alexithymia could account for differences in empathy. Moreover, sex seems to play a role in the relationship between autistic characteristics and TEI such that differences are especially prominent for males.

Autistic and non-autistic adults use discourse context to determine a speaker's intention to request.

The current study focuses on how autistic adults utilize context to determine whether ambiguous utterances (e.g., "I'm thirsty") are intended as indirect requests or as literal comment/questions. Two questions are addressed: (1) How do autistic adults compare to neurotypical adults in using context to interpret an utterance's intention as either literal or a request? (2) What cognitive mechanisms correlate with indirect request interpretation, and are these different for participants in each group? Twenty-six autistic and 26 neurotypical college students participated, engaging in an online experiment where they read narratives that ended with utterances open to literal or request interpretations, based on context. After each narrative, participants selected the best paraphrase of the utterance from two options, literal versus request. Following this task, participants completed two mentalizing measures (a false belief and emotion-identification task) and several executive functioning tests. The best model for predicting paraphrase choice included scores on the emotion-identification task and context as main effects, along with the interaction between both. Participants with higher emotion-identification test scores were more likely to provide correct paraphrases. Models including group as a main effect and/or interaction were not better at fitting the data, nor were any models that included executive functioning measures as main effects or interactions. Emotion-identification test scores, but not autism diagnosis, predict how adults infer whether an utterance is a request. Findings suggest that autistic adults use context similarly to neurotypical adults when interpreting requests, and that similar processes underlie performance for each group.

Extending Double Empathy: Effects of Neurotype-Matching on Communication Success in an Expository Context.

Milton's theory of double empathy posits that the difference in communication styles between people of different neurotypes contributes to mutual misunderstandings. The current quasi-experimental study seeks to expand on research indicating that matched neurotype pairs tend to communicate more effectively than mixed neurotype pairs by examining communication across and within neurotypes in an expository language context. Thirty autistic adults and 28 nonautistic adults were paired in either a matched neurotype or mixed neurotype condition. The pairs' interactions involved giving and listening to directions to draw an image. Interactions were recorded, transcribed, and coded for communication accuracy, rate, and clarity. Participants also completed a survey about the rapport they experienced in the interaction. Matched neurotype pairs were significantly more accurate in their communication than mixed neurotype pairs. Rate was fastest among mixed neurotype pairs, but clarity did not differ significantly across conditions. Matched autistic pairs reported significantly lower rapport than other pairs. This finding lends further support to the neurodiversity model by demonstrating that autistic communication is not inherently deficient. Further research is necessary to investigate a variety of influences on rate, clarity, and rapport development. Clinical implications include considerations for neurodiversity-affirming communication supports for expository contexts such as classroom directions or workplace instructions.

Insistence on sameness, repetitive negative thinking and mental health in autistic and non-autistic adults.

Autistic people are more likely to have mental health problems than non-autistic people. We know that having repetitive and negative thoughts can contribute to multiple mental health problems such as depression and obsessive-compulsive disorder. Autistic people often do the same behaviours repetitively, and they may also have more repetitive thinking styles. This could contribute to higher rates of mental health problems in autistic people. In this research, we wanted to find out if higher rates of repetitive behaviours contributed to depression and anxiety, and whether this relationship was because of repetitive negative thinking. We asked three groups of autistic adults to take part in the research. Sixty-seven autistic clinical participants were recruited from clinical settings and had moderate depression. Fifty-four autistic community participants and 66 non-autistic community participants were recruited from community settings. All participants completed measures of repetitive behaviours; a measure of anxiety and depression; and two measures of repetitive negative thinking (ruminating and obsessing). Autistic community participants had significantly higher repetitive behaviours, rumination and obsessing scores than non-autistic community participants. We found that higher rates of repetitive behaviours contributed to more repetitive thinking (obsessing and ruminating), which contributed to higher rates of depression and anxiety. The higher rates of repetitive negative thinking found in autistic individuals may contribute to higher rates of mental health problems in this group. Mental health assessments and interventions for autistic people should therefore consider the role of multiple forms of repetitive negative cognition and behaviour, which cut across diagnostic categories such as anxiety, depression and obsessive-compulsive disorder. These should be considered when aiming to understand why individuals develop mental health conditions and why these conditions persist.

Exploring Neurodiverse Collaboration Between Autistic and Non-autistic Adults in an Online Setting: A Pilot Study

Employment is an important aspect of independent adulthood, yet autistic adults typically face substantial barriers in the labor market, including high rates of un- and under-employment. To promote an inclusive workplace, the present study explored collaboration dynamics between autistic and non-autistic adults as they worked toward shared team goals in an online setting. We recruited nine dyads, including three dyads of non-autistic adults with an autistic adult (NA-AA), and six dyads of non-autistic adults (NA-NA). Our findings demonstrated that neurodiverse collaboration (autistic and non-autistic adults together) could lead to improved task efficiency at the group level and higher perceived team performance in individuals. However, in these collaborative settings, autistic adults reported higher levels of depression, anxiety, and stress compared to their non-autistic partners. Our findings demonstrate the unique contributions that autistic adults may bring into the workplace and highlight the need to develop workplace technologies supporting their collaborative experiences.

Validation of the camouflaging autistic traits questionnaire short form (CATQ-SF)

BackgroundCamouflaging of autistic traits involves hiding or compensating for autistic characteristics, often due to stigma or a desire to fit in with others. This behaviour has been associated with mental health issues in autistic individuals. The 2 5-item Camouflaging Autistic Traits Questionnaire (CAT-Q) is the most commonly used self-report measure of camouflaging. In this study, a 9-item short form version was developed for use in clinical and research settings. Aims: To construct and psychometrically validate a brief self-report measure of camouflaging. MethodThe Camouflaging Autistic Traits Questionnaire – Short Form (CATQ-SF) was developed and its factor structure and psychometric properties were evaluated in two studies. Study 1 used a large, online sample of autistic and non-autistic adults (N = 832) to evaluate the factor structure, psychometric properties, and measurement invariance of the CATQ-SF. Study 2 used an independent sample of autistic and non-autistic adults (N = 80) to test Study 1's findings. ResultsIn Study 1, evidence for a three-factor structure was observed, with good internal consistency (combined autistic & non-autistic α = 0.84). In addition, the instrument demonstrated measurement invariance, and reliably predicted higher levels of autistic traits. In Study 2, the 3-factor structure was replicated, and good internal consistency was again observed (combined autistic and non-autistic α = 0.89). In both studies, psychometric properties were of similar or higher validity compared to the full-form CAT-Q. ConclusionsThe CATQ-SF can be used by clinicians and researchers to measure camouflaging in autistic and non-autistic adults quickly and reliably.

Non-COVID Respiratory Infections Related Emergency Room Visits Among Autistic Adults in the United States

IntroductionThis is a retrospective study to examine the risk of non-COVID-19 respiratory infection (RI) related emergency department (ED) visits and hospitalizations among autistic adults compared to non-autistic adults using the 2018 Healthcare Cost and Utilization Project Nationwide Emergency Department Sample (HCUP-NEDS). MethodsThe data were analyzed in 2022 using the ICD-10-CM codes to extract about 46,996 autistic case records that were matched by age and sex with non-autistic records (140,997) in a 1:3 case-control ratio. Respiratory infections were also identified using the ICD-10-CM codes and classified by type. Logistic regression models were conducted for the likelihood of presenting with RI infections to the ED and subsequent hospitalization. All models were adjusted for covariates. ResultsAutistics were more likely to present with any type of respiratory infection at the emergency department (AOR = 1.83: CI= 1.69-2.42), lower respiratory infections (AOR=1.37: CI=1.09-1.50), and pneumonia (AOR=2.42: CI=1.98-2.47) compared to non-autistics. They are also more likely to be hospitalized from RIs during ED visits (AOR=3.87: CI=3.21-4.30), including upper and lower RIs, pneumonia, and bronchitis. ConclusionsAutistic individuals were more likely to experience emergency department visits and hospitalizations due to respiratory infections compared to non-autistic individuals. Amid growing evidence of the disproportionate impact of COVID-19 on the autistic population, our findings highlight a broader, pre-existing burden of respiratory infections among autistic adults in the US that extends beyond the recent pandemic.

Memory strategies in autistic and older adults.

Memory strategies in autistic adults seem to mimic strategies at older age, as both younger autistic and older non-autistic individuals use fewer semantic features in visual memory tasks. Therefore, the current study aims to investigate whether early differences in memory strategies lead to altered age-related effects in autism, particularly whether initial difficulties in strategy use become advantageous at older age (i.e., "protective aging"). A total of 147 participants across four groups (autistic younger/older, non-autistic younger/older) completed an online assessment. This assessment included a recognition version of the Visual Patterns Test (VPT) to evaluate semantic strategy use in visual memory, the Just Noticeable Difference (JND) size task for assessing visual processing, and the Multifactorial Memory Questionnaire to evaluate subjective memory functioning and strategy use (MMQ). Unexpectedly, all groups benefited from semantic features on the VPT, although the older groups performed less accurately and slower than the younger groups. The JND Size task showed no group differences. Autistic adults rated their MMQ memory as worse than non-autistic adults, despite reporting greater strategy use. These results indicate that cognitive strategies might be more similar between younger/older and autistic/non-autistic people than previously expected, although notable discrepancies between objective and subjective measures were present. They also substantiate previously reported parallel (i.e., similar) age-related effects between autistic and non-autistic people.

Do autistic adults spontaneously reason about belief? A detailed exploration of alternative explanations.

Southgate et al.'s (Southgate 2007 Psychol. Sci. 18, 587-92 (doi:10.1111/j.1467-9280.2007.01944.x)) anticipatory-looking paradigm has presented exciting yet inconclusive evidence surrounding spontaneous mentalizing in autism. The present study aimed to develop this paradigm to address alternative explanations for the lack of predictive eye movements on false-belief tasks by autistic adults. This was achieved through implementing a multi-trial design with matched true-belief conditions, and both high and low inhibitory demand false-belief conditions. We also sought to inspect if any group differences were related to group-specific patterns of attention on key events. Autistic adults were compared with non-autistic adults on this adapted implicit mentalizing task and an established explicit task. The two groups performed equally well in the explicit task; however, autistic adults did not show anticipatory-looking behaviour in the false-belief trials of the implicit task. Critically, both groups showed the same attentional distribution in the implicit task prior to action prediction, indicating that autistic adults process information from social cues in the same way as non-autistic adults, but this information is not then used to update mental representations. Our findings further document that many autistic people struggle to spontaneously mentalize others' beliefs, and this non-verbal paradigm holds promise for use with a wide range of ages and abilities.

Measuring self and informant perspectives of Restricted and Repetitive Behaviours (RRBs): psychometric evaluation of the Repetitive Behaviours Questionnaire-3 (RBQ-3) in adult clinical practice and research settings

BackgroundBrief questionnaires that comprehensively capture key restricted and repetitive behaviours (RRBs) across different informants have potential to support autism diagnostic services. We tested the psychometric properties of the 20-item Repetitive Behaviours Questionnaire-3 (RBQ-3), a questionnaire that includes self-report and informant-report versions enabling use across the lifespan.MethodIn Study 1, adults referred to a specialised adult autism diagnostic service (N = 110) completed the RBQ-3 self-report version, and a relative or long-term friend completed the RBQ-3 informant-report version. Clinicians completed the abbreviated version of the Diagnostic Interview for Social and Communication Disorders (DISCO-Abbreviated) with the same adults as part of the diagnostic process. For half of the assessments, clinicians were blind to the RBQ-3 ratings. We tested internal consistency, cross-informant reliability and convergent validity of the RBQ-3. In Study 2, a follow-up online study with autistic (N = 151) and non-autistic (N = 151) adults, we further tested internal consistency of the RBQ-3 self-report version. We also tested group differences and response patterns in this sample.ResultsStudy 1 showed good to excellent internal consistency for both self- and informant-report versions of the RBQ-3 (total score, α = 0.90, ω = 0.90, subscales, α = 0.76-0.89, ω = 0.77-0.88). Study 1 also showed cross-informant reliability as the RBQ-3 self-report scores significantly correlated with RBQ-3 informant-report scores for the total score (rs = 0.71) and subscales (rs= 0.69-0.72). Convergent validity was found for both self and informant versions of the RBQ-3, which significantly correlated with DISCO-Abbreviated RRB domain scores (rs = 0.45-0.54). Moreover, the RBQ-3 scores showed significantly weaker association with DISCO -Abbreviated scores for the Social Communication domain, demonstrating divergent validity. Importantly, these patterns of validity were found even when clinicians were blind to RBQ-3 items. In Study 2, for both autistic and non-autistic groups, internal consistency was found for the total score (α = 0.82-0.89, ω = 0.81-0.81) and for subscales (α = 0.68-0.85, ω = 0.69-0.85). A group difference was found between groups.LimitationsDue to the characteristics and scope of the specialist autism diagnostic service, further testing is needed to include representative samples of age (including children) and intellectual ability, and those with a non-autistic diagnostic outcome.ConclusionsThe RBQ-3 is a questionnaire of RRBs that can be used across the lifespan. The current study tested its psychometric properties with autistic adults without intellectual disability and supported its utility for both clinical diagnostic and research settings.

Assessment of Social Connection among Autistic and Non-Autistic Adults: A Proof of Concept Study for the Connections with Others Scales.

A gap exists in measures available to assess levels of motivation, desire, and value associated with connecting with others. Moreover, few social connection scales have been developed with a goal of including autistic individuals in the sample to create a measure that has utility across neurodiverse populations. This study aims to develop a measure to assess different facets of social connection that is valid among both autistic and non-autistic adults. The sample consisted of 200 participants recruited online. Participants completed an initial set of 35 items. Exploratory factor analyses and confirmatory factor analyses were performed. Four-factor models were produced by the EFAs. Item reduction resulted in the development of two 8-item scales: the Connections with Others Scale (CWOS) intended for the general population and the CWOS-Autistic Version (CWOS-AV) intended for autistic populations (CWOS-AV). Autistic participants had significantly greater motivation/desire to connect with others compared to non-autistic participants (t(195) = 3.39; p < 0.001). These measures will allow for greater ability to assess the motivation to connect with others, resulting in improved ability to produce research that clarifies theories and describes psychological phenomena.

Putting the Spotlight Back Onto the Flanker Task in Autism: Autistic Adults Show Increased Interference from Foils Compared with Non-autistic Adults.

Autistic people may have a less focused spotlight of spatial selective attention than non-autistic people, meaning that distracting stimuli are less effectively suppressed. Previous studies using the flanker task have supported this suggestion with observations of increased congruency effects in autistic participants. However, findings across studies have been mixed, mainly based on research in children and on response time measures, which may be influenced by differences in response strategy between autistic and non-autistic people rather than differences in selective attention. In this pre-registered study, 153 autistic and 147 non-autistic adults completed an online flanker task. The aims of this study were to test whether increased congruency effects replicate in autistic adults and to extend previous work by fitting a computational model of spatial selective attention on the flanker task to the data. Congruency effects were increased in the autistic group. The modelling revealed that the interference time from the foils was increased in the autistic group. This suggests that the activation of the foils was increased, meaning suppression was less effective for autistic participants. There were also differences in non-interference parameters between the groups. The estimate of response caution was increased in the autistic group and the estimate of perceptual efficiency was decreased. Together these findings suggest inefficient suppression, response strategy and perceptual processing all contribute to differences in performance on the flanker task between autistic and non-autistic people.
