Can eye-movements predict ultimate success?

Scientists call for experiments that can explore the functional relation between eye fixation measures and learning outcome measures. Such functional relations could be studied by arranging experiments involving complex human behavior as MTS tasks and ocular responses as fixation rates and duration. As for results on such experiments, participants who demonstrate equivalence class formation (a) reveal longer fixation times to sample stimulus presentation during training; (b) longer fixation times to both sample and comparison stimuli on incorrect trials; and (c) irrespective of equivalence class formation, participants fixate longer and more often to correct comparisons (i.e., S+ stimuli)—a finding that has implications with respect to eye-movements predictive value of delayed emergence of equivalence classes. In a systematic replication, we therefore ask the following question: Can eye-movements predict ultimate success?
