Orientation During Initial Learning and Subsequent Discrimination of Faces  (1997)
Abstract Header
ABSTRACT- Discrimination of facial features degrades with stimulus rotation (e.g., the "Margaret Thatcher" effect). Thirty-two observers learned to discriminate between two upright, or two inverted, faces. Images, erect and rotated by 45, 90, 135, and 180 about the line of sight, were presented on a computer screen. Initial discriminative reaction time increased with stimulus rotation only for observers who learned the upright faces. Orientation during learning is critical in identifying faces subsequently seen at different orientations.
