abstract = {Autism spectrum disorder (ASD) is a neurodevelopmental
condition with a highly heterogeneous adult phenotype that
includes social and non-social behavioral characteristics.
The link between the characteristics assignable to the
different domains remains unresolved. One possibility is
that social and non-social behaviors in autism are modulated
by a common underlying deficit. However, here we report
evidence supporting an alternative concept that is
individual-centered rather than deficit-centered.
Individuals are assumed to have a distinctive style in the
strategies they adopt to perform social and non-social tasks
with these styles presumably being structured differently
between autistic individuals and typically-developed (TD)
individuals. We tested this hypothesis for the execution of
time-coordinated (synchronized) actions. Participants
performed (i) a social task that required synchronized gaze
and pointing actions to interact with another person, and
(ii) a non-social task that required finger-tapping actions
synchronized to periodic stimuli at different time-scales
and sensory modalities. In both tasks, synchronization
behavior differed between ASD and TD groups. However, a
principal component analysis of individual behaviors across
tasks revealed associations between social and non-social
features for the TD persons but such cross-domain
associations were strikingly absent for autistic
individuals. The highly differentiated strategies between
domains in ASD are inconsistent with a general
synchronization deficit and instead highlight the
individualized developmental heterogeneity in the
acquisition of domain-specific behaviors. We propose a
cognitive model to help disentangle individual-centered from
deficit-centered effects in other domains. Our findings
reinforce the importance to identify individually
differentiated phenotypes to personalize autism
therapies.Keywords: Adults; Autism; Cross-domain;
