Navigating Mixed-Neurotype Dialogue: Environmental and Affective Influences on Autistic Speakers.

In this reflective report study, we examined communication challenges for autistic adults by examining the influences of emotional state and environmental context across neurotype conversation partners. Using the Neurotype Communication and Assistive Technology Survey (NCATS), we surveyed 165 autistic adults (18-35 years old) and analyzed 154 responses to capture both quantitative ratings and qualitative descriptions of past contextual conversations. The majority of the participants noted that environmental factors, such as crowdedness, noise levels, and familiarity, at least somewhat impacted their communication. Autistic adults reported that noisy or unpredictable settings were associated with word loss, scripting, and social withdrawal, while quiet and familiar spaces facilitated openness and authentic self-expression. In addition, participants stated that conversations with allistic (non-autistic) partners required more conscious effort, social masking, and cognitive load than conversations with autistic partners, consistent with the Double Empathy Problem. Finally, survey responses revealed that negative emotions such as stress, frustration, and anxiety may worsen communication difficulties regardless of the conversation partner's neurotype, whereas positive emotions such as happiness and calmness were found to improve fluency, confidence, and intersubjectivity. These results indicate that partner neurotype, emotional states, and other environmental factors can affect communication challenges for autistic adults.Lay AbstractIn this study, autistic adults reflected on their conversational experiences and described what helped communication go well and what made it more difficult. We asked 165 autistic adults (18-35 years old) to complete a survey about how they communicate in different situations based on people and places and received 154 responses. We focused on how communication changed whether the other person is autistic or allistic (non-autistic). Within that, we focused on two main factors: the type of environment they were in (e.g., home, work, school) and how their emotions (feeling happy, sad, angry) affected their communication. The majority of autistic adults said that the place they were in at least somewhat affected their communication. Autistic adults said that loud or unpredictable places often made communication harder, leading to things like losing words, repeating scripts, or pulling back from the conversation. Quiet and familiar spaces, on the contrary, made it easier to share thoughts openly. Talking with allistic people usually took more effort and sometimes led to masking, or hiding one's natural way of communicating. This fits with the Double Empathy Problem, which says that communication struggles often come from mismatched understandings between autistic and allistic people. Emotions were also important. Stress, anxiety, or frustration made conversations harder, while happiness and calmness made conversing easier and improved confidence. Overall, our findings suggest that reducing sensory stress, supporting emotional well-being, and encouraging mutual understanding can make conversations better for both autistic and allistic people.
