The ability to recognize facial expressions of emotion is a critical part of human social interaction. Infants improve in this ability across the first year of life, but the mechanisms driving these changes and the origins of individual differences in this ability are largely unknown. This thesis used eye tracking to characterize infant scanning patterns of expressions. In study 1 (n = 40), I replicated the preference for fearful faces, and found that infants either allocated more attention to the eyes or the mouth across both happy and fearful expressions. In study 2 (n = 40), I found that infants differentially scanned the critical facial features of dynamic expressions. In study 3 (n = 38), I found that maternal depressive symptoms and positive and negative affect were related to individual differences in infants’ scanning of emotional expressions. Implications for our understanding of the development of emotion recognition are discussed. Key Words: emotion recognition, infancy eye tracking, socioemotional development

Our environments are saturated with learnable information. What determines which of this information gets prioritized for limited attentional resources? While previous studies suggest that learners prefer medium complexity information, here we argue that what counts as medium should change as someone learns an input's structure. Specifically, we examined the hypothesis that attention is directed towards more complicated structures as learners gain more experience with the environment. Participants watched four simultaneous streams of information which varied in complexity. Reaction times to intermittent search trials (Ex. 1, N=75) and eye-tracking (Ex. 2, N=45) indexed where participants attended over the experiment. Using a subject- and trial-specific measure of complexity, we demonstrated that participants attended to increasingly complex streams over time. Individual differences in structure learning also modulated attention allocation, with better learners attending to complex structures from earlier in learning, suggesting the ability to prioritize different information over time gates structure learning success.

AbstractThe eye movement analysis with hidden Markov models (EMHMM) method provides quantitative measures of individual differences in eye-movement pattern. However, it is limited to tasks where stimuli have the same feature layout (e.g., faces). Here we proposed to combine EMHMM with the data mining technique co-clustering to discover participant groups with consistent eye-movement patterns across stimuli for tasks involving stimuli with different feature layouts. Through applying this method to eye movements in scene perception, we discovered explorative (switching between the foreground and background information or different regions of interest) and focused (mainly looking at the foreground with less switching) eye-movement patterns among Asian participants. Higher similarity to the explorative pattern predicted better foreground object recognition performance, whereas higher similarity to the focused pattern was associated with better feature integration in the flanker task. These results have important implications for using eye tracking as a window into individual differences in cognitive abilities and styles. Thus, EMHMM with co-clustering provides quantitative assessments on eye-movement patterns across stimuli and tasks. It can be applied to many other real-life visual tasks, making a significant impact on the use of eye tracking to study cognitive behavior across disciplines.

Style is an important aspect of literature, and stylistic deviations are sometimes labeled foregrounded, since their manner of expression deviates from the stylistic default. Russian Formalists have claimed that foregrounding increases processing demands and therefore causes slower reading – an effect called retardation. We tested this claim experimentally by having participants read short literary stories while measuring their eye movements. Our results confirm that readers indeed read slower and make more regressions towards foregrounded passages as compared to passages that are not foregrounded. A closer look, however, reveals significant individual differences in sensitivity to foregrounding. Some readers in fact do not slow down at all when reading foregrounded passages. The slowing down effect for literariness was related to a slowing down effect for high perplexity (unexpected) words: those readers who slowed down more during literary passages also slowed down more during high perplexity words, even though no correlation between literariness and perplexity existed in the stories. We conclude that individual differences play a major role in processing of literary texts and argue for accounts of literary reading that focus on the interplay between reader and text.
