due to the prevalence of alexithymia in autistic people rather than autism itself. Autistic people experience deficits in their ability to develop, maintain, and understand relationships, as well as difficulties adjusting behavior to fit social contexts. ASD presents with impairments in pragmatic communication skills, such as difficulty initiating a conversation or failure to consider the listener's interests to sustain a conversation. The ability to be focused exclusively on one topic in communication is known as monotropism, and can be compared to "tunnel vision". It is common for autistic people to communicate strong interest in a specific topic, speaking in lesson-like monologues about their passion instead of enabling reciprocal communication. What may look like self-involvement or indifference to others stems from a struggle to recognize or remember that other people have their own personalities, perspectives, and interests. Another difference in pragmatic communication skills is that autistic people may not recognize the need to control the volume of their voice in different social settings; for example, they may speak loudly in libraries or movie theaters. Autistic people display atypical nonverbal behaviors or have difficulties with nonverbal communication. They may make infrequent eye contact: an autistic person may not make eye contact when called by name, or may avoid eye contact with an observer. Aversion of gaze can also be seen in anxiety disorders, but poor eye contact in autistic children is not due to shyness or anxiety; rather, it is overall diminished in quantity. Autistic people may struggle with both production and understanding of facial expressions. They often do not know how to recognize emotions from others' facial expressions, or may not respond with appropriate facial expressions. They may have trouble recognizing subtle expressions of emotion and identifying what various emotions mean for the conversation. A defining feature is that autistic people have social impairments and often lack intuitions about others that many people take for granted. Temple Grandin, an autistic woman involved in autism activism, described her inability to understand the social communication of neurotypicals, or people with typical neural development, as leaving her feeling "like an anthropologist on Mars". They may also not pick up on body language or social cues such as eye contact and facial expressions if they provide more information than the person can process at that time. They struggle with understanding the context and subtext of conversational or printed situations, and have trouble forming resulting conclusions
