<p>Social communication deficits and restricted repetitive behavior symptoms in Tourette syndrome</p>

“…Conversely, some areas of overlap between TS and ASD may exist not just at the level of outcome but at the level of the underlying mechanism. One obvious place for this is in the co-occurrence of atypical features in social cognition and motor function existing in both disorders, and in the potential for a shared mechanism being at least somewhat responsible for this link 18. Whilst the current study on the domain level found a close concordance between the two disorders on RRS and less on social or communication scores, it would be of great interest to study this aspect of overlap and whether task-based and neuroimaging studies showed similarities in ASD and TS populations with respect to links between social cognition and motor ability.…”

“…Previous studies have found that individuals with TS have poorer expressive and receptive language compared with matched controls, and that abnormal speech patterns are sometimes present 17. There is also a growing body of evidence of a link between atypical motor function and deficits in social cognition, such as understanding another’s nonverbal communication of feelings, desires, or intentions 18. This link is more strongly evidenced in ASD than in TS populations due to a scarcity of studies focusing on TS,18 and while no clear direction of causality has been established, if the same link were to be reliably found in both populations it could hold further keys regarding potential shared mechanisms underlying features of ASD and TS.…”

Neurocognitive Predictors of Understanding of Intentions in Parkinson Disease

“…It is very likely that dopamine plays a pivotal role in ToM performance, which is illustrated by sociocognitive deficits in other disorders connected with dopamine dysfunction such as schizophrenia, Tourette syndrome, and Huntington disease. 15,45 Nevertheless, there is still a controversial effect of dopaminergic treatment on cognition that must be taken into consideration. On one hand, levodopa treatment has a beneficial effect on executive functions, including attention, set-shifting, working memory, and planning, 46 -48 but on the other hand, excessive dopamine doses have a harmful effect on reward-based control of behavior tasks such as decision-making under ambiguity 49 which is an integral part of the Comic Strip Task.…”

“…Social cognition abilities are closely related to motor functions, which are a priori impaired in patients with PD. A recent review article by Eddy et al 15 highlighted 2 relevant mechanisms of this interplay. In the early stage of the disease, a “simulation route” is probably more applicable in which patients are failing to connect observed movement with emotional states via deficient self-activation of unique motor codes.…”

Differences Between Autistic and Non-autistic Adults in the Recognition of Anger From Dynamic Expressions Remain After Controlling for Alexithymia.

“…In our study, we used PLF videos that were made by lming four neurotypical participants posing different emotional states. Given that autistic and neurotypical individuals may produce different facial expressions and that one's own movement patterns in uence the perception and interpretation of the movements of others (Cook, 2016;Eddy & Cook, 2018;Edey, Yon, Cook, Dumontheil, & Press, 2017;Happé, Cook, & Bird, 2017) our autistic participants might have struggled to read emotion in our PLF videos because the expressions were dissimilar to expressions that they would have adopted themselves. To date studies that have documented differences between autistic and control participants in the production of facial expressions of emotion have used neurotypical observer ratings as a measure of the quality of facial expression (i.e.…”
