Individuals with autism spectrum disorders (ASD) have notable language difficulties, including with understanding narratives. However, most narrative comprehension studies have used written or spoken narratives, making it unclear whether narrative difficulties stem from language impairments or more global impairments in the kinds of general cognitive processes (such as understanding meaning and structural sequencing) that are involved in narrative comprehension. Using event-related potentials (ERPs), we directly compared semantic comprehension of linguistic narratives (short sentences) and visual narratives (comic panels) in adults with ASD and typically-developing (TD) adults. Compared to the TD group, the ASD group showed reduced N400 effects for both linguistic and visual narratives, suggesting comprehension impairments for both types of narratives and thereby implicating a more domain-general impairment. Based on these results, we propose that individuals with ASD use a more bottom-up style of processing during narrative comprehension.

Wide continuum of associated cognitive and neurobehavioral disorders, including, but not limited to, three core-defining features: impairments in socialization, impairments in verbal and nonverbal communication, and restricted and repetitive patterns of behaviors. (from DSM-V)
Visual impairments limiting one or more of the basic functions of the eye: visual acuity, dark adaptation, color vision, or peripheral vision. These may result from EYE DISEASES; OPTIC NERVE DISEASES; VISUAL PATHWAY diseases; OCCIPITAL LOBE diseases; OCULAR MOTILITY DISORDERS; and other conditions. Visual disability refers to inability of the individual to perform specific visual tasks, such as reading, writing, orientation, or traveling unaided. (From Newell, Ophthalmology: Principles and Concepts, 7th ed, p132)
Qualified professionals trained in primary eye and vision care, including measurement of visual abilities, diagnosing disorders of the visual system and provision of treatment such as prescriptions for correction of visual defects with lenses or glasses and vision therapy.
A childhood disorder predominately affecting boys and similar to autism (AUTISTIC DISORDER). It is characterized by severe, sustained, clinically significant impairment of social interaction, and restricted repetitive and stereotyped patterns of behavior. In contrast to autism, there are no clinically significant delays in language or cognitive development. (From DSM-IV)
These disorders are related to both SCHIZOPHRENIA SPECTRUM AND RELATED DISORDERS and DEPRESSIVE DISORDERS in terms of symptomatology, family history, and genetics. (DSM-V) .
