Neural fingerprints of behavioural rigidity in autism
EEG and behavioural measures combined
Empirical evidence for behavioral rigidity and autism comes from studies showing that autistic individuals tend to repeat tasks more than their neurotypical peers. The main objective of this study was to specify the neural fingerprints of behavioral rigidity in autism.
The study replicated a stronger bias repetition and task choice in autistic participants and a larger slowing down in performance after choosing to switch tasks. Accordingly, the EEG data demonstrated an attenuated CNV in autistic participants, typically indicating a weaker intentional task preparation.
Combining behavioral measures with EEG markers seems as a promising tool to further investigate the origins of behavioral rigidity in autism.
