A Within-Participant Study on Tracked Eye-Movement Measures across Training Structures

The analysis of eye-movements, obtained with Eye-tracking Technology, during Matching-to-Sample Performance, extends and enriches our behavioral attempts to understand complex human behavior (Hansen & Arntzen, 2015). Previous group studies from our eye-tracking research lab suggest that topographically different eye-movement and observing response measures, such as duration, rate, variability, pattern, and speed, emerge during the establishment of stimulus equivalence classes that are formed using different training structures (e.g., Hansen & Arntzen, 2013, October; Hansen & Arntzen, 2014, May). In a systematic replication, introducing a within-participant design, we intend to establish five 3-member classes in a concurrent training format by exposing all participants to one of three conditional discrimination training sequences that involve the Many-to-One, One-to-Many, and Linear Series training structures. Preliminary results suggest differences in the fixation measures duration, rate, and sequence as a function of order of learning conditions and in eye-movement speed as a function of both order of learning conditions and variation in motivation.
