Sam is teaching Elliot to identify bath items while in the bathroom. Sam says, "Show me the paper towels," but Elliot starts to point to the automatic hand dryer. Sam blocks the response, represents the SP, and immediately prompts Elliot to select the paper towels. Then he throws in a distractor trial such as, "Show me your hands" or says, "Say, washing." Next, he re-presents the original S (test trial) "Show me the paper towels." Sam is using which type of error correction strategy? Active response error correction Four-step error correction Directed rehearsal error correction Feedback-only error correction
