What intervention method starts by teaching a child to exchange a picture for a desired item?

The Picture Exchange Communication System (PECS) is an intervention method specifically designed to enhance communication abilities in individuals, particularly those with autism spectrum disorder and other communication challenges. This method begins by teaching a child to exchange a picture of a desired item for the actual item itself. Through this process, children learn to communicate their needs and desires using visual symbols, which is especially beneficial for those who may struggle with verbal communication.

PECS encourages active participation and interaction, allowing children to express themselves in a straightforward manner. The initiation of this exchange helps build the foundational skills needed for more complex communication, as children progress through different phases of the PECS protocol, eventually learning to construct simple sentences and engaging in more sophisticated forms of communication.

In contrast, the other options do not specifically focus on teaching picture exchanges as a communication method. Applied Behavior Analysis (ABA) is a broader behavioral intervention that focuses on modifying behavior through reinforcement strategies. Symbolic Play Therapy utilizes play to facilitate emotional expression and communication, while AAC Device Use involves the use of electronic devices or software for communication purposes, rather than starting with a picture exchange method. Each of these methods serves distinct purposes and may involve different techniques or goals compared to PECS.
