“…In contrast, the likelihood of making errors in the VI task was reduced with age in the ASD group. This can be taken as evidence for delays in the development of motor representations in ASD, likely relating to the motor planning and performance disturbances shown in previous research including the same children [ 20 ]. However, both tasks were more difficult for the children with ASD than controls at all ages.…”

“…It has been proposed that such prospective (or predictive) control deficits may contribute to the movement deficits observed in ASD [ 16 , 17 , 18 ]. Investigations into the functions of prospective control mechanisms of the motor system in ASD have been operationalized through measurements of different movement kinematics and the coordination between hand and eye movements during actual performance [ 6 , 19 , 20 ]. The results suggest that there are deviances in ASD with regard to the orchestration of multiple action plans into precise overall planning and the following execution of action sequences [ 6 , 20 ].…”

Development of Motor Imagery in School-Aged Children with Autism Spectrum Disorder: A Longitudinal Study

et al. 2022

Autism spectrum disorder (ASD) is a diagnosis based on social communication deficits and prevalence of repetitive stereotyped behaviors, but sensorimotor disturbances are commonly exhibited. This longitudinal study aimed at exploring the development of the ability to form mental motor representations (motor imagery; MI) in 14 children with ASD and 17 typically developing (TD) children at 7, 8 and 9 years of age. MI was investigated using a hand laterality paradigm from which response times (RT) and error rates were extracted and compared with performance on a visually based mental rotation task (VI). A criterion task was used to ensure that the children could perform the task. The results showed wide performance variability in the ASD group with more failures than TD in the MI criterion task, especially at 7 years. For all age levels and both the MI and VI tasks, the error rates were significantly higher and RTs longer for the ASD group compared with TD. Signs of MI strategies were however noted in the ASD group as biomechanically constrained orientations had longer RTs than less constrained orientations, a RT pattern that differed from the VI task. The presence of MI in the ASD group was most evident at 9 years, but the error rates remained high at all ages, both in the MI and VI task. In comparison, the TD group showed stable MI strategies at all ages. These findings indicate that MI ability is delayed and/or impaired in children with ASD which may be related to difficulties performing required mental rotations.

“…Posers producing the expressions used in Studies 1 and 2 (from the “standard” condition of Brewer et al, 2016) could not see the expressions they were producing. Some autistic people have difficulty making use of interoceptive feedback (e.g., DuBois et al, 2016; Hatfield et al, 2019), and they may have difficulty with motor control (e.g., Bäckström et al, 2021; Gowen & Hamilton, 2013; Hughes, 1996; MacNeil & Mostofsky, 2012; Schmitz et al, 2003). Without the availability of any visual feedback in the standard condition, perhaps some autistic posers “overshot” the expressions they intended to make (resulting in relatively good/intense expressions).…”

Non‐autistic adults can recognize posed autistic facial expressions: Implications for internal representations of emotion

et al. 2023

Autistic people report that their emotional expressions are sometimes misunderstood by non-autistic people. One explanation for these misunderstandings could be that the two neurotypes have different internal representations of emotion: Perhaps they have different expectations about what a facial expression showing a particular emotion looks like. In three well-powered studies with non-autistic college students in the United States (total N = 632), we investigated this possibility. In Study 1, participants recognized most facial expressions posed by autistic individuals more accurately than those posed by non-autistic individuals. Study 2 showed that one reason the autistic expressions were recognized more accurately was because they were better and more intense examples of the intended expressions than the non-autistic expressions.In Study 3, we used a set of expressions created by autistic and non-autistic individuals who could see their faces as they made the expressions, which could allow them to explicitly match the expression they produced with their internal representation of that emotional expression. Here, neither autistic expressions nor non-autistic expressions were consistently recognized more accurately. In short, these findings suggest that differences in internal representations of what emotional expressions look like are unlikely to play a major role in explaining why non-autistic people sometimes misunderstand the emotions autistic people are experiencing. Lay SummaryAutistic people report that non-autistic people sometimes misunderstand what they are feeling. We investigated whether misunderstandings arise because the two neurotypes have different expectations about what emotional expressions look like. In three studies, we found no evidence for this possibility. Overall, nonautistic participants recognized autistic people's expressions at least as well as (and often better) than non-autistic people's expressions. Our findings suggest that the two neurotypes do not have different expectations about what emotional expressions look like. Other factors contribute to misunderstandings about emotion.

“…Movement patterns in children (Beaudette & Chester, 2013;Simon-Martinez et al, 2018) and older adults (Lulic et al, 2018) are different than in young adults, and the baseline among young adults cannot be used to accurately assess movement quality for children or older adults. The inclusion of children and older adults in database is especially important for disorders that are more prominent among children and older adults, such as autism spectrum disorder (Bäckstrom et al, 2021), cerebral palsy (Butler & Rose, 2012), and stroke (Kwakkel et al, 2019). Moreover, the effects of age can i.…”
