Background:

Human face recognition is rapid despite a vast number of stored representations.
A potential mechanism involves encoding distinctive features onto a prototypical face, aiding computational speed.
Understanding distinguishing features is key to explaining this efficiency.

Purpose of the Study:

To investigate the features that distinguish individual faces.
To identify features forming the basis of a prototypical face.
To analyze the saliency of facial features in recognition tasks.

Main Methods:

Developed and applied the distributed apertures technique.
Divided target faces into 162 contiguous squares for display.

Related Experiment Videos

Presented combinations of 24 or fewer squares for 1-second trials.

Computed proportion of correct responses for each square.

Main Results:

Generated brightness maps illustrating feature saliency.
Confirmed previous findings on facial feature importance.
Revealed novel and surprising details regarding inter-face differences.

Conclusions:

The distributed apertures technique effectively maps facial feature saliency.
Results provide insights into the computational strategies of human face recognition.
Highlights the complex interplay of features in distinguishing between faces.
