Autism' was first described by :

Question

Accepted Answer

Autism was first described by Leo Kanner, making Option 2 the correct answer. Here is a detailed explanation supporting this choice:

1. **Leo Kanner**: In 1943, Leo Kanner, an Austrian-American psychiatrist, published a seminal paper titled "Autistic Disturbances of Affective Contact," in which he described a group of children with distinct behavioral characteristics. Kanner's work is widely recognized as the first formal description of autism as a unique condition, and he is credited with identifying the core features of autism that are still relevant in today's diagnostic criteria. His observations laid the foundation for subsequent research and understanding of autism spectrum disorders.

2. **Samuel Kirk**: Samuel Kirk was an American psychologist known for his work in the field of special education, particularly in learning disabilities. While he made significant contributions to the understanding and education of children with learning difficulties, he did not describe or identify autism. Therefore, Option 1 is incorrect in the context of who first described autism.

3. **B. F. Skinner**: B. F. Skinner was a renowned American psychologist and behaviorist known for his work on operant conditioning and behavior analysis. Skinner's research focused on behavior modification and reinforcement, but he did not describe or identify autism. His work was more concerned with general principles of behavior rather than specific developmental disorders like autism, making Option 3 incorrect.

4. **J. B. Watson**: J. B. Watson was an American psychologist who established the psychological school of behaviorism. His work emphasized the study of observable behavior and the effects of environmental stimuli, but he did not describe or identify autism. Watson's contributions were more aligned with behaviorist theories rather than the identification of specific conditions like autism, rendering Option 4 incorrect.

In summary, Leo Kanner's pioneering work in 1943 is the reason why Option 2 is the correct answer. His identification and description of autism as a distinct condition have had a lasting impact on the field of psychology and the understanding of autism spectrum disorders.
