The study revealed the brain mechanisms of audio-visual time integration windows in people with split and autism traits

When watching TV and movies, have you ever experienced the situation of "out-of-step sound and painting"? Character mouth type and sound in time can not match, video screen slow half shot or fast half shot affect the viewing enjoyment.
study found that sensitive perception of visual and auditory information is time-misplaced, making it more difficult for people with autism and schizophrenia to use time proximity clues to accurately separate unrelated stimuli and tend to misbuy time-out-of-control audio-visual information.
this unusually large "audio-visual time integration window" may be closely related to clinical manifestations such as perceived sensory experience anomalies and social communication disorders.
autism and schizophrenia are considered "disease continuums", i.e. there are "subclinical groups" in healthy populations that exhibit similar but less cognitive and emotional impairments to patients.
, are there abnormalities in the ability to integrate audio-visual time among subclinical schizophrenic and autistic populations? Behind the individual differences in the audio-visual time integration window, what is the corresponding brain mechanism? By studying the relationship between audio-visual time integration windows and splitting traits and autism traits between 155 college students, the Chen Chu overseas Chinese Research Group of the Mental Health Key Laboratory of the Institute of Psychology of the Chinese Academy of Sciences collected data on static magnetic function imaging, and initially explored the brain function connection patterns related to audio-visual time integration capabilities.
study found that the ability to detect time misalactations in audio-visual information was not affected by different levels of divisive and autistic traits. The relevant analysis of the connection between the
and the resting state function shows that the function connection between the left cortical cortical layer and the left wedge front lobe is stronger, the weaker the functional connection between the left calf and the outer frontal lobe of the right back, the smaller the audio-visual time integration window of speech, that is, the higher the sensitivity of audio-visual out-of-step awareness.
, however, for the time integration ability of non-verbal audio-visual stimulation, the stronger the functional connection between the left and right-hand side, the larger the nonverbal audio-visual time integration window.
The study looked at the relationship between audio-visual time integration capabilities and two subclinical traits (split traits, autism traits) at the same time, and initially revealed the brain mechanism of the audio-visual time window, and found that the functional connection between the brain regions responsible for sensory integration and time processing may be the brain mechanism behind the individual differences in the time-integrated window.
research has been funded by the National Key Research and Development Project, the National Natural Science Foundation of China and the Mental Health Key Laboratory of the Chinese Academy of Sciences.
the findings were published online on Autism Research.
