Which behavior change in young children is most likely due to delays in expressive language development?

The behavior change most likely due to delays in expressive language development is the frustration stemming from an inability to convey thoughts, which can subsequently lead to acting out. When young children experience delays in their ability to express themselves verbally, they often struggle to communicate their needs, feelings, and ideas. This frustration can manifest in various ways, including tantrums, aggression, or withdrawal, as children may not know how to cope with the communication barriers they face.

Children rely on language as a primary tool for social interaction; thus, delays in expressive language can hinder their ability to engage with peers and adults effectively. When they cannot express what they want or how they feel, the resultant frustration may trigger acting out behaviors as a means of coping or to elicit responses from others. Understanding this connection is crucial for educators and counselors as they develop strategies to support children's communication skills and behavioral health.
