It's this unforced, spontaneous quality to their laughter that other people seem to find appealing. Children with autism mainly produce one sort of laughter — voiced laughter, which has a tonal, song-like quality. This type of laughter is associated with positive emotions in typical controls.
Oftentimes, children with autism do not understand humor and will laugh even when the situation is not funny. This is called the unshared laughter. This spontaneous nature of their giggling is what adds to their charm. However, their laughter can be so untimely and this causes them trouble.
One particularly rich indicator of social differences in autism is the voice. Children with autism often sound different from other people. Some may speak in a flat, monotone voice; others may use unusual modulation or stress different words or parts of words in their speech; and some may speak at an increased volume.
Young children may express more voiced than unvoiced laughter, as they haven't yet learned to purposely laugh. The test group of autistic children laughed just about as often as the non-autistic kids, but the autistic children's laughter was 98 percent voiced, while non-autistic children produced both types.
Facial expressions smooth social interactions: A smile may show interest, a frown empathy. People with autism have difficulty making appropriate facial expressions at the right times, according to an analysis of 39 studies1. Instead, they may remain expressionless or produce looks that are difficult to interpret.
Children with autism have a broader or wider mouth and philtrum - the groove below the nose, above the top lip.
Some of the frequent facial features of autism are a broader upper face, shorter middle face, wider eyes, bigger mouth, and the philtrum [19]. The use of facial features as a physical marker to detect autism is one of the most exciting topics in autism research.

Some children with autism smile to show they're happy but don't share their enjoyment. Others show little facial expression or have flat affect and rarely smile so you may not know when they're happy.
They found that although the autistic children did not differ from the younger, typically developing children in the amount of time spent looking at their own faces, but that they did spend a lot more time looking at objects in the mirror, and that their behavior toward their reflections differed from that of either ...
In the case of vocal stimming (or verbal stimming), the child might make noises such as groaning, grunting, high- pitched screeching, squealing, humming, or repeating random words, words to a familiar song, phrases, or lines from a movie.
Main signs of autism
finding it hard to understand what others are thinking or feeling. getting very anxious about social situations. finding it hard to make friends or preferring to be on your own. seeming blunt, rude or not interested in others without meaning to.
Many kids and teens with autism make frequent sounds and noises when excited or anxious. These vocalizations — which can sound loud or quiet, high-pitched or low-pitched, happy or upset — are often a form of self-stimulatory behavior (stimming).
Children with ASD often need a hug, just like other children. Sometimes they need this much more than other children. But some children don't like to be touched. Respect their personal space.
Research says that autistic children spend more time on screen than children who do not have autism. About 64.2 percent of young adults with ASD spend their free time on TV, and video games and 13.2 percent of young adults with ASD spend time on social media sites, emails, and chatting.
When children with autism speak they sound different from most people. Their speech usually follows one of several characteristic patterns: Some talk in a flat, toneless voice, others in an exaggerated, hyper way that doesn't match the subject matter.
About stimming and autism
Stimming might include: hand and finger mannerisms – for example, finger-flicking and hand-flapping. unusual body movements – for example, rocking back and forth while sitting or standing. posturing – for example, holding hands or fingers out at an angle or arching the back while sitting.
Repetitive behaviour
For example, children might: make repetitive noises like grunts, throat-clearing or squealing. do repetitive movements like body-rocking or hand-flapping. do things like flicking a light switch repeatedly.
not consistently use gestures on their own – for example, they might not wave bye-bye or clap without being asked to, or they might not nod for yes or shake their head for no.
Many autistic people stim when they're excited and happy, not just to defuse feelings of being overstimulated or distressed. 2 While most stims aren't harmful, some behaviors can be. Stimming can also become a problem if behaviors persist for hours or become a daily occurrence.
For babies who cannot yet speak, smiling is key. Grins convey an infant's emotional state and well-being and can help get a parent's attention and care. A new study reports that by the time they turn 1, infants who are later diagnosed with autism smile less often than those who do not develop the disorder.
People with autism often speak with a different rhythm, prosody, and/or volume than typical peers. Thus, even if the words themselves are appropriate, they may sound flat, loud, soft, or otherwise different. It's not unusual for people with autism to "script" their conversations.
Can You Diagnose Autism by Paying Attention to a Child's Eyes? Yes. A study by Washington State University shows autistic children had a different visual response to light.
Overall, our results clearly show that individuals with autism are not completely blind to aesthetic pleasure: in fact, they retain an implicit ability to experience beauty.
In previous studies, children with autism have been found to have unusually wide faces and wide-set eyes. The cheeks and the nose are also shorter on their faces (Aldridge et al., 2011).
