Mental Time Travel (MTT) refers to the cognitive ability to mentally project oneself backward in time to recall past events or forward in time to anticipate future scenarios. In relation to autism, MTT research explores how individuals with autism may experience differences in episodic memory and future-oriented thinking, potentially leading to challenges in recalling specific personal events or imagining detailed future scenarios.

PlainSpeak: Mental Time Travel (MTT) is our brain’s way of thinking back to past memories or imagining what might happen in the future. For people with autism, MTT might work differently, sometimes making it harder to remember personal events or imagine future plans. [Read in more detail, a PlainSpeak Version]

Monotropism and special interests are closely related yet distinct constructs within the context of autism. Both concepts elucidate how autistic individuals exhibit profound engagement with specific domains, yet they underscore different facets of this phenomenon.
Monotropism is a cognitive model positing that autistic individuals exhibit a narrowed attentional focus on a limited set of interests, in contrast to the broader attentional distribution observed in neurotypical individuals. This heightened attentional focus facilitates deep expertise and significant enjoyment in specialized areas. However, it also results in attentional inflexibility, making it challenging for individuals to shift focus to other tasks or interests that do not align with their core interests. Monotropism provides a framework for understanding why autistic individuals often demonstrate exceptional proficiency in their areas of passion but may face difficulties with tasks that are outside these focal points.
Special Interests refer to the specific topics or activities that elicit intense focus and enthusiasm in autistic individuals. These interests often manifest as lifelong passions and serve as sources of comfort, identity, and competence. While special interests contribute positively to an autistic individual's life, they may be misunderstood or undervalued by others who fail to recognize their significance.
Neurocognitive explanations for both monotropism and special interests suggest that these behaviors are underpinned by fundamental differences in brain function and information processing in autistic individuals. Monotropism is thought to involve an atypical allocation of cognitive resources, where autistic individuals preferentially allocate their cognitive bandwidth to areas of high personal significance. This preferential allocation can be understood through the lens of predictive coding theories, particularly those emphasizing 'slow-updating' and 'high-precision' or 'hypoprior' mechanisms. These theories propose that autistic individuals maintain highly precise and stable internal models for their areas of interest, leading to profound engagement and expertise in these domains but also to challenges in adapting to new or less predictable tasks.
Special interests, on the other hand, may be conceptualized as emergent properties of these underlying neurocognitive mechanisms. The intense focus and enthusiasm associated with special interests reflect the heightened precision and stability of the predictive models governing these interests. The sustained engagement with special interests can be further understood through the framework of neural reward pathways, where dopaminergic activity reinforces behaviors that align with these precise internal models, thereby enhancing the salience and reward value of special interests.
Understanding both monotropism and special interests from a neurocognitive perspective can inform the development of supportive environments that leverage the strengths of autistic individuals. By recognizing and building upon their focused cognitive styles, educators, clinicians, and caregivers can implement strategies that accommodate attentional inflexibility while fostering opportunities for growth and adaptation. This approach not only acknowledges the unique cognitive profiles of autistic individuals but also promotes their overall well-being and societal inclusion.
Here are the different versions to help understand Monotropism and Special Interests
Special interests in autism are intense and highly focused areas of interest that individuals may pursue with great enthusiasm and expertise, often serving as a source of comfort and a means of coping with sensory and social challenges.
PlainSpeak: Special interests are topics or activities that autistic people are extremely passionate about and know a lot about, which can be both a hobby and a way to feel comfortable.

Monotropism in autism refers to a cognitive tendency toward deep focus on specific interests or tasks, often leading to intense concentration and reduced awareness of broader contexts or multiple stimuli.
PlainSpeak: Monotropism is when someone, often an autistic person, focuses deeply on one thing, making it hard to pay attention to other things around them.

Understanding Stress and Anxiety in Autism: The Role of the HPA Axis
Stress and anxiety are common experiences for everyone, but for individuals with autism, these feelings can be particularly intense and challenging. Understanding why this happens involves delving into the body’s stress response system, known as the hypothalamic-pituitary-adrenal (HPA) axis."It was a thought provoking read about an angle that I hadn’t thought of. It is also beautifully written."

Our brains constantly change how neurons (nerve cells) communicate to help us learn and remember things. Some of these changes happen very quickly and are known as short-term synaptic plasticity. This is when the connection strength between two neurons changes for a few seconds to a few minutes. Two important types of these changes are paired pulse facilitation (PPF) and paired pulse depression (PPD).
Paired Pulse Facilitation (PPF) happens when two signals arrive close together at a neuron connection, and the second signal is stronger than the first. This is because the first signal leaves behind some calcium, which helps release more chemical messengers for the second signal, making it stronger.
Paired Pulse Depression (PPD) is the opposite. When two signals come close together, the second signal is weaker. This happens because the first signal uses up most of the available chemical messengers, leaving fewer for the second signal.
These short-term changes are important for how our brains process information. In autism, scientists have found that these changes can be different. For example, certain gene mutations linked to autism can affect how well these short-term changes work. Some of these genes, like SYN1 and SYN2, help control the availability of chemical messengers at neuron connections. Mutations in these genes can lead to an imbalance in brain activity, making some signals too strong and others too weak (Frontiers, 2015) (Frontiers).
Other studies have shown that mutations in another gene, neuroligin-3, which is also linked to autism, can change how neurons communicate in different parts of the brain. These mutations can increase the strength of certain signals and disrupt the balance of brain activity (Molecular Psychiatry, 2015) (Nature). This imbalance can contribute to some of the behaviors seen in autism.
Understanding these short-term brain changes helps scientists learn more about how autism affects the brain and can lead to new ways to help people with autism.

Sometimes I have to wonder about how inclusive the term neurodiverse itself is.
For example there is an assumption that "to disclose or not to disclose" is a problem for every ND person in higher ed or employment.
Autism Lexicon: Diagnostic Overshadowing
Diagnostic overshadowing in autism occurs when the symptoms and behaviors associated with autism obscure or overshadow the presence of other mental or physical health conditions. This can lead to misdiagnosis, underdiagnosis, or delayed diagnosis of other conditions, ultimately impacting the individual's overall care and treatment outcomes.
PlainSpeak: Diagnostic overshadowing in autism is when doctors focus too much on autism and miss other health problems because they think it must be all because of autism.
