E–S theory was developed by psychologist Simon Baron-Cohen in 2002, [10] as a reconceptualization of cognitive sex differences in the general population. This was done in an effort to understand why the cognitive difficulties in autism appeared to lie in domains in which he says on average females outperformed males, along with why cognitive strengths in autism appeared to lie in domains in ...
The scientific study of the causes of developmental disorders involves many theories. Some of the major differences between these theories involves whether environment disrupts normal development, if abnormalities are pre-determined, or if they are products of human evolutionary history which become disorders in modern environments (see evolutionary psychiatry).

Diseases such as measles can cause severe disabilities and even death, so the risk of death or disability for an unvaccinated child is higher than the risk for a child who has been vaccinated. [189] Despite medical evidence, antivaccine activism continues. A developing tactic is the "promotion of irrelevant research to justify the science ...
It instead situates human cognitive variation in the context of biodiversity and the politics of minority groups. [3] [4] [5] Some neurodiversity advocates and researchers including Judy Singer and Patrick Dwyer argue that the neurodiversity paradigm is the middle ground between a strong medical model and a strong social model.

Twin studies provide a unique opportunity to explore the genetic and environmental influences on autism spectrum disorder (ASD). By studying identical twins, who share identical DNA, and fraternal twins, who share about half of their DNA, researchers can estimate the heritability of autism by comparing the rates of when one twin is diagnosed with autism while the other is not in identical vs ...
Autism spectrum disorder [a] (ASD), or simply autism, is a neurodevelopmental disorder characterized by repetitive, restricted, and inflexible patterns of behavior, interests, and activities; deficits in social communication and social interaction; and the presence of high or low sensory sensitivity.
Asperger syndrome (AS), also known as Asperger's syndrome or Asperger's, was a diagnosis used to describe a neurodevelopmental disorder characterized by significant difficulties in social interaction and nonverbal communication, along with restricted, repetitive patterns of behavior and interests. [5]
The extreme exercise of social valuation of human difference is in the definition of "human." Differences between humans can lead to an individual's "nonhuman" status, in the sense of withholding identification, charity, and social participation. Views of these variations can change enormously between cultures over time.
