In terms of memory studies, which is a characteristic that is noted about lower-functioning autism?

• A. High levels of episodic recall
• B. Presence of semantic deficits
• C. Unusual strength in relational memory
• D. Visible improvements with age

Answer: (B)

The characteristic noted about lower-functioning autism, particularly in memory studies, is the presence of semantic deficits. Individuals with lower-functioning autism often struggle with understanding and producing language, which leads to challenges in their semantic memory – the aspect of memory that involves the storage and recall of facts, concepts, and the meanings of words. These deficits can impact their ability to communicate effectively and grasp abstract concepts, which is fundamental in developing their language skills.

In contrast, high levels of episodic recall refer to the ability to remember specific events or experiences in a detailed manner, which is not typically associated with lower-functioning autism. Relational memory involves recognizing the relationship between different pieces of information; while some individuals might show strengths in specific contexts, this is not a characteristic commonly noted across the board for lower-functioning autism. Lastly, visible improvements with age can occur in various areas of development, but this is not a defining characteristic for this group, as developmental trajectories may greatly vary among individuals with autism.
