“…This training consists of an oculomotor task (memory-guided saccades) for 2 min and a revised Stroop test (several exercises lasting 8 min). Concerning memory-guided tasks, children had to fixate on the central fixation target in the middle of the PC's screen (see Caldani et al, 2022). After the fixation period, a stimulus appeared for 300 ms on the right or the left side of the screen at 20 degrees of eccentricity.…”

Cognitive remediation therapy interventions could improve cognitive functioning in subjects with autism. To investigate the benefit of a short cognitive training rehabilitation in children with autism spectrum disorder (ASD) on pursuit and fixation performances. We recruited two groups (G1 and G2) of 30 children with ASD, sex‐, IQ‐ and age‐matched (mean 11.6 ± 0.5 years), and pursuit and fixation eye movements were recorded twice at T1 and T2. Between T1 and T2, a 10‐min cognitive training was performed by the G1 group only, whereas the G2 group had a 10‐min of rest. For all children with ASD enrolled in the study, there was a positive correlation between restricted and repetitive behaviour scores of both Autism Diagnostic Interview‐Revised (ADI‐R) and the Autism Diagnostic Observation Schedule (ADOS) and the number of saccades recorded during the fixation task at T1. At T1, oculomotor performances were similar for both groups of ASD children (G1 and G2). At T2, we observed a significant reduction in the number of saccades made during both pursuit and fixation tasks. Our findings underlined the importance to promote cognitive training rehabilitation for children with ASD, leading to a better performance in inhibitory and attention functioning responsible for pursuit and fixation eye movement's performance.

“…Alternatively, gaze differences could be due, perhaps partially, to basic differences in oculomotor control. Although some studies have reported abnormal saccade kinematics (including latency, duration, and accuracy) in ASD (Caldani et al, 2023; Goldberg et al, 2002; Luna et al, 2007; Luna et al, 2008; Schmitt et al, 2014; Wilkes et al, 2015), others have not (Avni et al, 2021; Johnson et al, 2016). Yet, another alternative is that the eye gaze patterns were determined not only by the dynamic changes in the stimulus but also due to excessive sensorimotor variability, found in autism in other domains such as body movements (Torres et al, 2013; Torres & Denisova, 2016); which was not captured by the analyses of basic saccade and fixation properties.…”

A variety of studies have suggested that at least some children with autism spectrum disorder (ASD) view the world differently. Differences in gaze patterns as measured by eye tracking have been demonstrated during visual exploration of images and natural viewing of movies with social content. Here we analyzed the temporal randomness of saccades and blinks during natural viewing of movies, inspired by a recent measure of “randomness” applied to micro‐movements of the hand and head in ASD (Torres et al., 2013; Torres & Denisova, 2016). We analyzed a large eye‐tracking dataset of 189 ASD and 41 typically developing (TD) children (1–11 years old) who watched three movie clips with social content, each repeated twice. We found that oculomotor measures of randomness, obtained from gamma parameters of inter‐saccade intervals (ISI) and blink duration distributions, were significantly higher in the ASD group compared with the TD group and were correlated with the ADOS comparison score, reflecting increased “randomness” in more severe cases. Moreover, these measures of randomness decreased with age, as well as with higher cognitive scores in both groups and were consistent across repeated viewing of each movie clip. Highly “random” eye movements in ASD children could be associated with high “neural variability” or noise, poor sensory‐motor control, or weak engagement with the movies. These findings could contribute to the future development of oculomotor biomarkers as part of an integrative diagnostic tool for ASD.
