We assessed the effects of blocking on the accuracy of arranging visual stimuli in sequences as an attempt to assess whether verbal behavior mediates nonverbal performance. Across three experiments, college students were trained to echo and tact the names of abstract images vocally (Experiments 1 and 3) and with hand signs (Experiment 2), and…

Adaptive learning techniques have typically scheduled practice using learners' accuracy and item presentation history. We describe an adaptive learning system (Adaptive Response Time Based Sequencing--ARTS) that uses both accuracy and response time (RT) as direct inputs into sequencing. Response times are used to assess learning strength and to…
