Our brains evaluate sensory information from the environment and use it to guide behaviour. This shapes how we interact with the world and ultimately, our physical and mental well-being. Understanding the mechanisms of perceptual decision-making is of relevance for neurodiverse populations such as autistic individuals. Here I present findings from experimental psychology, computational modelling, and brain imaging (including ultra-high-resolution Magnetic Resonance Spectroscopy) that show a) the behavioural similarities and differences between autistic and non-autistic adults during perceptual decision-making, and b) the relationships between neurotransmitters, autistic traits, and perceptual choice in adults. By integrating novel computational modelling approaches with classic task paradigms, this line of research helps bridge the gaps between neurochemistry and cognition and offers new insights into the cognitive neuroscience of autism.
