Which of the following is not a behavior typically exhibited in the second year of life associated with a later diagnosis of ASD?

• A. Limited engagement in playing with toys and other objects
• B. High levels of vocalization
• C. Frequent eye contact
• D. Imitation of others' actions

Answer: (A)

In understanding the behaviors associated with the early development of individuals who may later be diagnosed with Autism Spectrum Disorder (ASD), it's important to recognize that certain social and communicative behaviors are typically less pronounced or absent.

Limited engagement in playing with toys and other objects is indeed a red flag that can be associated with a later diagnosis of ASD. Children at this age often show interest in engaging with their environment, including both toys and interactions with other people. In contrast, high levels of vocalization, frequent eye contact, and imitation of others’ actions are generally expected behaviors during the second year of life.

Vocalization is a key component of early language development, and children typically exhibit a range of vocal sounds, including babbling and attempts at speech. Eye contact is crucial for social interaction and communication, serving as an important indicator of engagement and connection with caregivers and peers. Additionally, imitation of actions signifies social learning, where a child learns and understands norms and behaviors by observing others.

Therefore, recognizing that limited engagement in play is not a behavior expected in healthy development during the second year is vital. It reflects a potential difficulty in social engagement, which is a hallmark of autism spectrum disorders.
