Temporal Binding Window and Autism

[Concepts in Sensorimotor Research]

Temporal binding window (TBW) refers to the specific time frame during which the brain integrates and processes information from different sensory modalities. It is the period in which the brain combines and links stimuli occurring close in time and attributes them to a single event. This window is crucial for the perception of synchrony and the formation of coherent perceptual experiences.

In autistics, research suggests alterations in the TBW due to difficulties in accurately perceiving and integrating sensory information across different modalities, leading to difficulties in forming a unified perception of the world.

One aspect of the TBW that has been extensively studied in relation to autism is audiovisual integration. Typically, individuals are sensitive to the relative timing of auditory and visual stimuli and can perceive them as belonging to a single event when presented within a certain temporal proximity. However, studies have shown that autistics may have a broader or more extended TBW. This means that they require a longer temporal proximity between auditory and visual stimuli to perceive them as synchronized.

This winder TBW has implication in terms of social communication and interaction since the perception of synchrony is crucial for understanding and interpreting non-verbal cues such as facial expressions, gestures, and vocal intonations. Difficulties in integrating sensory information across different modalities can also contribute to sensory processing issues commonly observed in individuals with autism, such as hypersensitivity or hyposensitivity to certain stimuli.

TBW may also influence higher-level cognitive processes such as attention, perception of causality, and the ability to predict and anticipate events. Disruptions in these processes can impact the ability to understand the temporal structure of events and may contribute to difficulties with executive functioning.

Ubuntu

I came across this word today in our Public Voice Fellowship Training. 

Ubuntu as a framework has so many things that apply to autism advocacy, research, inclusivity, belonging, and the need for increasing knowledge and solutions in the autism space. More specifically I want to highlight. 

• Community-based approach to support autistics and their families.
• Emphasis on empathy and understanding, belonging and inclusivity
• Collaboration and cooperation which means working together to increase knowledge and solutions across the autism space instead of this conflict and undermining that is going on. We can find solutions for everyone, its not a one-size fits all. 

Ubuntu is the "I" in the "We"

Ubuntu is a philosophy that originated in Southern Africa, particularly among the Bantu peoples of South Africa, Zimbabwe, and Zambia. It is a philosophy that emphasizes the interconnectedness of all things and the importance of community, compassion, and respect for others.

At its core, the philosophy of Ubuntu is based on the idea that a person is a person through other people. Its the "I" in the "We." 

This means that individuals are not defined by their own accomplishments or achievements, but by their relationships with others and their contributions to the community. In other words, one's sense of self is deeply tied to their interactions with others and their ability to make a positive impact on the world around them.

Ubuntu also emphasizes the importance of compassion, empathy, and forgiveness. It encourages individuals to see the humanity in others, to treat everyone with respect and kindness, and to forgive others for their mistakes. This is based on the belief that everyone is connected, and that we are all responsible for creating a more just and equitable world.

Joy is the beauty that surrounds us, waiting to be noticed

Ventriloquism Effect in Multisensory Integration

[Concepts in Sensorimotor Research]

The ventriloquism effect is a fascinating example of multisensory integration, the process by which the brain combines information from different senses to create a unified percept. The brain is integrating information from the visual and auditory senses to create the perceive that the sound is coming from a location (the dummy's mouth) that is different from the actual source of the sound.

The ventriloquism effect can also occur in other situations where there is a mismatch between the visual and auditory information, such as when watching a movie with dubbed audio, or when hearing a person speak on a phone or speaker. The brain uses contextual cues to determine the location of the sound source and can be influenced by visual information, leading to the perception of the sound coming from a different location.

There is some evidence to suggest that autistics may process sensory information differently than neurotypicals, including the processing of auditory information and less fooled by the ventriloquism effect which may suggest that autistics have difficulty integrating information form different senses (which has implication in terms of social interactions).

Other studies have suggested that individuals with autism may have heightened sensitivity to certain auditory stimuli and may experience difficulty in filtering out irrelevant sounds. This hypersensitivity to sound could potentially interfere with the integration of visual and auditory information, leading to a weaker ventriloquism effect.

However the caveat is that research on the relationship between autism & ventriloquism effect is ongoing and not fully understood. So nothing is set in stone.

Sarcasm and the Literal Thinker stereotype

An autism stereotype I heard during a recent talk was "sarcasm hit-or-miss," as further evidence of a child being autistic.

But isn't "sarcasm hit-miss" is equally true of the NT population, as not everyone gets sarcasm.  

Sarcasm is not an autistic identifier and this idea seems to derive from another misconception;  

that ALL autistics must be only literal thinkers.  

 

Optimism is the lens through which we can see the world in its most beautiful form.

Cellular Neuroscience grade

I made an A in this super tough Cell Neuroscience course, filled with baffling weekly quizzes; a course which consumed most of my life this semester. 

OMG. 

 

Doing things no one can imagine

Like moi?  Deja Vu!! 

Who could have imagined I could get to do what I'm doing now. I've finished 1 year of Grad School. 

I'm still in awe and wonderstruck.

ASQ: Ages and Stages Questionnaires

The Ages and Stages Questionnaires (ASQ) is a developmental screening tool designed to assess the developmental progress of children from birth to 5 years of age.

The ASQ is a parent-reported questionnaire that assesses various domains of child development, including communication, fine and gross motor skills, problem-solving, personal-social skills, and adaptive behaviors. It is used to identify potential developmental delays or concerns and determine the need for further evaluation or intervention.

Limitations of the ASQ include the reliance on parent-reported information, which may be subject to biases or inaccuracies.

Scoring and Interpretation:
The ASQ uses a scoring system based on the number and nature of items that the child has achieved. Each item is scored as "yes," "sometimes," or "not yet." The scores are used to identify potential developmental concerns or delays. There are established cutoff scores for each age-specific questionnaire that help determine if further evaluation or intervention is needed.

The ASQ was developed by Jane Squires and Diane Bricker in the 1990s.
