What does "developmental delay" refer to?

Developmental delay refers to a significant delay in reaching developmental milestones in one or more areas of functioning, such as cognitive, physical, communication, social, or emotional skills, and is typically identified in children aged 3 to 9 years. Option A accurately captures this definition as it specifies that the delay is significant and not attributable to other disabilities, which is essential for proper diagnosis and intervention.

In contrast, the other options are more limited in scope. One option focuses solely on physical development, which does not encompass the broader range of potential developmental concerns that may include cognitive and emotional aspects. Another option emphasizes emotional issues impacting learning, which, while relevant, does not fully represent the broader concept of developmental delays, as it narrows the focus to just one specific area. Lastly, describing it as a temporary setback in cognitive skills could mislead, as developmental delays are typically identified as more persistent issues that may require ongoing support rather than situations that are merely temporary.
