    Recognizing faces is harder when their view changes. Familiar faces are recognized faster and more accurately than unfamiliar ones, even with view changes.

    Area of Science:

    • Cognitive Psychology
    • Neuroscience
    • Human Perception

    Background:

    • Facial recognition is a complex cognitive process.
    • The ability to recognize familiar faces is crucial for social interaction.
    • Changes in facial viewpoint can impact recognition accuracy and speed.

    Purpose of the Study:

    • To investigate how changes in facial view (angle, expression) affect recognition accuracy and latency.
    • To compare recognition performance for familiar versus unfamiliar faces under varying view conditions.

    Main Methods:

    • Two experiments were conducted using unfamiliar and familiar faces.
    • Facial views were manipulated (angle, expression, or both) between presentation and test phases.
    • Recognition accuracy and response latency were measured.

    Main Results:

    • Unchanged faces were recognized faster and more accurately than changed faces.
    • Changes in angle or expression individually impaired recognition less than combined changes.
    • Familiar faces were recognized more quickly and accurately than unfamiliar faces, with less impact from view changes.

    Conclusions:

    • Facial recognition relies on integrating multiple information codes (pictorial, structural, semantic, name).
    • Viewpoint changes significantly impact the recognition of unfamiliar faces.
    • Familiarity enhances facial recognition robustness against changes in viewpoint and expression.
