Does repetition make perfect? Comparing scanpaths over repeated visual search to investigate how scanpath similarity evolves with experience
(2017) PSYP01 20171Department of Psychology
- Abstract
- Visual search efficiency improves with repeated exposure to the same search problem, yet the mechanisms behind these search efficiency gains remain unclear. Investigating how eye-movement sequences evolve over repeated viewings is fundamental for understanding how skilful search develops over time and its role in learning and gaining expertise. Scanpath theory holds that repeated displays are investigated sequentially and in the same manner that they were initially encoded. Yet, new evidence suggests that eye movement sequences are only partly repeated and adapt with task experience. Twenty-five participants performed a complex visual search task, during which they were connected to an eye tracker. The results confirmed that the... (More)

Investigating how eye-movement sequences evolve over repeated viewings is fundamental for understanding how skilful search develops over time and its role in learning and gaining expertise. Scanpath theory holds that repeated displays are investigated sequentially and in the same manner that they were initially encoded. Yet, new evidence suggests that eye movement sequences are only partly repeated and adapt with task experience. Twenty-five participants performed a complex visual search task, during which they were connected to an eye tracker. The results confirmed that the presentation of repeated scenes leads to performance gains in both behavioural (search time, accuracy) and eye movement measures (number of fixations, scanpath similarity). Overall, our findings support the basic idea of scanpath theory and reveal that scanpath similarity unfolds over repetitions. The results suggest that with experience, observers adapt a more optimal strategy regarding scanpath shape, length and fixation position. Further research should uncover the mechanisms behind scanpath adaption and formation in individuals. (Less)
