This phenomenon, known as the preferential viewing effect, manifests rapidly and obligatorily, beginning within a second of presenting test items and peaking just before a response is made. However, little attention has been given in the literature to the factors influencing the magnitude of this effect. In a series of studies, I explore the relationship between the strength of relational memory and the extent of the preferential viewing effect, first, by introducing additional study episodes aimed at enhancing memory for item-scene pairs (Experiment 1), and second, by examining subjective confidence judgments in behavioral responses (Experiment 2). Moreover, inconsistencies exist in the literature regarding the relationship between pupil size fluctuations during learning and subsequent memory outcomes. I address this by investigating how pupil size fluctuations during learning relate to preferential viewing, which I demonstrate in Experiments 1 and 2 reflects the quality of relational binding of items to their context during learning. Finally, the role of viewing behavior during retrieval is a subject of debate in eye tracking and memory research. My approach to this complex issue involved providing evidence that initial viewing behavior indicates orientation to information in the environment consistent with retrieved memory. This body of work reveals that pupil dilations during learning and viewing behavior during retrieval are reflective of the quality of relational binding.
