Article Synopsis
- - The study investigated how participants' eye movements change when identifying upright and inverted faces based on two types of information: configural (relationship between features) and featural (specific features).
- - Two experiments were conducted—one where participants were unaware of the type of information relevant to the task, and another where they were informed— to see how prior knowledge affected their eye movement patterns.
- - Results showed that eye scanning patterns differ based on task demands; without prior knowledge, participants focused on the eyes, while with prior knowledge of relational information, they looked more at the center of the face.
In two experiments, we examined the effects of varying the spatial frequency (SF) content of face images on eye movements during the learning and testing phases of an old/new recognition task. At both learning and testing, participants were presented with face stimuli band-pass filtered to 11 different SF bands, as well as an unfiltered baseline condition. We found that eye movements varied significantly as a function of SF.
