Bottom Line: We used the composite-face illusion and Navon stimuli to determine the consequences of priming local or global processing on subsequent face recognition.Local processing of Navon stimuli did not influence the sensitivity to incongruence.We conclude that global processing of Navon stimuli augments holistic processing of the face.

ABSTRACT
We used the composite-face illusion and Navon stimuli to determine the consequences of priming local or global processing on subsequent face recognition. The composite-face illusion reflects the difficulty of ignoring the task-irrelevant half-face while attending the task-relevant half if the half-faces in the composite are aligned. On each trial, participants first matched two Navon stimuli, attending to either the global or the local level, and then matched the upper halves of two composite faces presented sequentially. Global processing of Navon stimuli increased the sensitivity to incongruence between the upper and the lower halves of the composite face, relative to a baseline in which the composite faces were not primed. Local processing of Navon stimuli did not influence the sensitivity to incongruence. Although incongruence induced a bias toward different responses, this bias was not modulated by priming. We conclude that global processing of Navon stimuli augments holistic processing of the face.

Mentions: As is shown in Fig. 4a, in the aligned condition, the processing level of Navon letters influenced the participants’ responses to faces, with the lowest sensitivity in the global–incongruent condition. No priming effects were found in any other condition.Fig. 4
