People with autism feel emotions deeply but express them differently, often showing a disconnect between internal feelings and external display, which can manifest as intense reactions (meltdowns/shutdowns), different facial expressions (less eye contact, "flat affect"), reliance on stimming (rocking, flapping), or difficulty verbalizing feelings, stemming from sensory processing differences or alexithymia. They may seem less expressive but experience profound emotions, processing them more effortfully or showing distress in ways others don't expect, like reacting strongly to routine changes.
Emotional processing time often takes longer in Autistic people as there can be more sensory information to process. The Autistic brain isn't always able to filter out as much unnecessary sensory input as non-autistic brains can. This can make emotional responses seem delayed.
Expressing Emotions / Emotional Regulation
Colloquially known as a meltdown or tantrum, it is common for children with autism to display intense anger or distress when unable to adapt to changes in routine, or in situations where they lack the ability to communicate effectively or meet expectations set for them.
Behaviors that are fairly common in children with autism, such as tantrums, hitting or injuring themselves or others, yelling, social withdrawal, and even extreme silliness, may stem from a problem with regulating emotions. And this difficulty may affect more than behavior.
1 in 5 autistic people have alexithymia. People who have alexithymia may have have trouble identifying, understanding and describing emotions. They may also struggle to show or feel emotions that are seen as socially appropriate, such as happiness on a joyous occasion.
The "6-second rule" for autism is a communication strategy where a speaker pauses for about six seconds after asking a question or giving information, giving the autistic person extra time to process it without feeling rushed, which helps reduce anxiety and allows for a more thoughtful response, reducing frustration for both parties. Instead of repeating or rephrasing, which can be confusing, you wait, and if needed, repeat the exact same words after the pause.
Examples of literal thinking in autism
Common colloquial phrases are sometimes taken literally by autistic individuals, who may misunderstand the meaning. For example, if someone says, “Break a leg” or “Hit the books,” a literal thinker might take it as actually breaking a leg or physically striking their books.
Around 90% of autism cases are attributed to genetic factors, meaning autism is highly heritable, with many different genes contributing, rather than a single cause, often interacting with environmental influences during early brain development, though specific environmental factors don't cause it but can increase risk. Twin studies show strong genetic links, with concordance rates between 60-90% in identical twins, and research points to complex interactions of many genes and prenatal/perinatal factors.
Five key signs of autism (ASD) involve difficulties with social communication, repetitive behaviors, intense interests, sensory sensitivities, and strict routines, such as trouble with small talk/eye contact, hand-flapping/lining things up, deep focus on specific topics, sensitivity to sounds/lights, and distress over schedule changes, though these vary widely.
"Looping" in autism refers to getting "stuck" in repetitive mental cycles, replaying thoughts, questions, worries, or phrases endlessly, often triggered by stress, sensory overload, or uncertainty, and linked to challenges with executive function and attention. It's a non-clinical term for perseveration or rumination, where an autistic individual's brain struggles to shift focus from an internal loop, which can be mentally exhausting but sometimes also comforting.
Seven key signs of autism spectrum disorder (ASD) often involve challenges with social communication (like avoiding eye contact, not responding to names), restricted/repetitive behaviors (like repetitive movements or strict routines), sensory sensitivities (unusual reactions to sounds, lights, textures), and difficulties with emotional understanding or verbal expression, though signs vary greatly and appear differently across ages. Key indicators include limited gestures, delayed speech, intense focus on specific objects, difficulty with pretend play, and strong distress when routines change.
An autistic person may demonstrate many problems with anger and impulse control when feeling depressed, for example, yelling for no apparent reason, throwing plates or a chair or punching a wall.
Meltdowns can be expressed verbally (eg, shouting, growling, or crying), physically (eg, kicking or flapping) or a mixture of both ways. An autistic person will lose control of their behaviour because they are completely overwhelmed and are unable to express themselves another way.
The Autism Spectrum Disorder person often has no idea what he or she is feeling, and even less how you are feeling. Discussions tend to stay at a superficial level, often focused on facts, ignoring subtly and nuance, and with little regard to multiple perspectives on any given position.
Many autistic people are motivated to have friends, relationships and close family bonds, despite the clinical characterisation of autism as a condition negatively affecting social interaction. Many first-hand accounts of autistic people describe feelings of comfort and ease specifically with other autistic people.
Other signs of autism
Autism red flags involve challenges with social communication (like avoiding eye contact, not responding to name by 12 months, lack of shared smiles/pointing) and restricted, repetitive behaviors (like hand-flapping, strong routines, lining up toys, intense fixations, sensory sensitivities, or loss of skills). Early signs in infants include no warm smiles by 6 months or no back-and-forth gestures by 12 months; regression (losing skills) is a major flag. If you notice these, seek immediate evaluation from your pediatrician.

Additionally, inherited genetic variations contribute greatly. Research shows that both mothers and fathers can carry autism-related gene variants. Some of these are common variants that increase the risk of autism, while others are rare mutations causing more severe effects.
Understanding the 6 stages of an autism meltdown can help parents, caregivers, and educators respond with empathy and support.
Changes in the diagnostic criteria and increased screening at wellness visits seem to be the main contributors.
Savant syndrome is a rare, but extraordinary, condition in which persons with serious mental disabilities, including autistic disorder, have some 'island of genius' which stands in marked, incongruous contrast to overall handicap.
Slow Down. Another thing that's important to do when you experience conflict is slow down and take deep breaths. Fights happen so fast and can easily trigger intense emotional responses that make conflict worse. It actually can be helpful to even ask for some time to process how you are feeling.
