Studies have revealed that visual timing processing sensitivity affects the feeling experience of adolescents with autism traits

Abnormal sensory processing capabilities are one of the outstanding clinical features of the autism spectrum disorder (ASD) group.
More than 90% of ASD individuals experience abnormal sensory experiences, and these sensory-related symptoms occur as early as inferfed, involving various sensory channels such as audio, hearing, smell, smell, and touch, and further affecting the patient's daily life and cognitive social function.
At present, there are two main branches of research to explore the sensory processing ability of ASD groups: First, clinicians and rehabilitation therapists through daily observation, interviews and questionnaire assessment, found that ASD patients' sensitivity to external sensory information is abnormally changed, in which sensory retardation, sensory allergy and sensory seeking are the most common clinical symptoms;
One of the consistent conclusions in these laboratory studies is that ASD patients are less able to use time cues to integrate and isolate audio-visual stimuli than healthy controls, i.e. they have difficulty accurately determining the chronological order of rapidly presenting visual or auditory stimuli, and are much less sensitive to perceived out-of-date audio-visual information.
While both clinical and scientific evidence supports the important role of sensory processing capabilities in the ASD community, few studies have explored how these two sides show how sensory processing capabilities are associated.
to solve these problems, the Chen Chu overseas Chinese Research Group, a key laboratory for mental health at the Chinese Academy of Sciences, conducted a study.
study recruited a group of adolescents (11-17 years old, 94) to complete a series of audio-visual time-series judgment tasks and simultaneous judgment tasks to examine their audio-visual time processing capabilities.
, all teenagers completed self-assessment questionnaires to reflect the sensitivity to sensory information and the level of autism traits. the
study found that adolescents with higher scores for autism traits performed worse in visual timing tasks, i.e. needed a larger time interval to accurately determine the order of two rapidly presenting visual stimuli, and scored higher on abnormal reaction sensitivity such as feeling slow and allergic.
analysis of sensory processing indicators at different levels found that the decline in sensitivity of visual timing judgment, rather than auditory or audio-visual time processing capabilities, was associated with the sensitivity of abnormal sensory information reactions.
study suggests that in healthy adolescent groups, sensory sensitivity is "visually specific" to time-processing capabilities.
sensitivity to visual timing may lead to the emergence of abnormal sensory experiences and further be associated with subclinical symptoms of ASD.
this, future training and intervention studies may consider "time processing capability of visual information" as the starting point to improve the abnormal sensation experience of the ASD population by increasing the sensitivity of time processing.
, the team has developed non-drug perceptual training for ASD children, which is expected to improve the clinical community's ability to feel integrated in the future.
