With which method are stimuli functionally independent of the environment?

Discrete Trial Training (DTT) utilizes structured and controlled approaches to teach skills to learners, making stimuli in this method functionally independent of the environment. In DTT, each trial is presented in a systematic format, often in controlled settings that minimize external distractions. This allows the focus to be placed solely on the task at hand, ensuring that the learner's responses are directly linked to the specific stimuli presented rather than influenced by environmental factors. By isolating the teaching stimuli in such a way, practitioners can assess and measure learners' responses accurately.

The other methods involve varying degrees of interaction with the environment. Natural Environment Teaching (NET) emphasizes teaching in the natural setting, where stimuli are inherently tied to the surrounding context, thus not fully independent. Discovery Learning encourages learners to explore and interact with their environment, leading to a dependence on varying stimuli. Holistic Education focuses on the overall development of the learner within their environment, which means that learning is deeply connected to contextual factors and not independent.
