Errorless learning is a teaching strategy designed to prevent the learner from making mistakes during the acquisition of a new skill This is typically achieved through highdensity intrusive prompting eg physical guidance full verbal prompts that ensures correct responses from the very beginning The goal is to avoid the learner practicing errors which can inadvertently reinforce incorrect behaviors or make them part of a behavioral chain Option D where the mom uses full physical handoverhand prompting through the entire chain is a classic example of errorless learning as it completely prevents errors Option A allows for errors to occur before prompting Option B allows for errors in selecting the shirt even after the initial prompt for the closets location Option C forward chaining typically allows for errors in earlier steps of the chain before reinforcement is delivered for the mastered steps and thus doesnt inherently prevent all errors throughout the entire sequence unless combined with an errorless prompting strategy for each step
