A unique look at face processing: the impact of masked faces on the processing of facial features

This experiment utilized a masked priming paradigm to explore the early processes involved in face recognition. The first experiment investigated implicit processing of the eyes and mouth in an upright face, using prime durations of 33 and 50 ms. The results demonstrate implicit processing of both the eyes and mouth, and support the configural processing theory of face processing. The second experiment used the same method with inverted faces and the third experiment was a combination of Experiments 1 and 2. The fourth experiment utilized misaligned faces as the primes. Based on the pattern of results from these experiments, we suggest that, when a face is inverted, the eyes and mouth are initially processed individually and are not linked until a later stage of processing. An upright face is proposed to be processed by analysis of its configuration, whereas an inverted face is initially processed using first-order relational information, and then converted to an upright representation and transferred to face specific regions for configural analysis.

The holistic hypothesis in face processing was tested in 3 experiments. Holistic processing was conceptualized as interactive influence of facial features on the perceptual representation of faces. In Experiment 1, 3 facial features (eye distance, width of nose, size of mouth) were varied on 3 values per feature. Photographs and blurred versions were used. Participants assigned each stimulus face to 1 of 2 target faces according to similarity. The data were evaluated by the logit model that provides a direct test of interactive influence of the features on participants' performance. The interactive-processing hypothesis was not confirmed. The results were replicated in Experiment 2, in which 2 features with 5 values each were used and data of individual participants were evaluated, and in Experiment 3, in which a reduced presentation time of 250 ms was used. It is concluded that facial features are processed and represented independently.

Thatcher and the Cheshire cat: context and the processing of facial features.

As has been noted before, a face made gruesome by the inversion of its mouth will not be so perceived when the entire construction is inverted. Results are presented which suggest that this is because the mouth and eye features are evaluated individually (although each feature may influence the evaluation of the other) and the mouth, whether normal or inverted, tends to have its uppermost part assigned as 'top', providing for either a pleasant smiling-mouth expression or a gruesome 'biting-intention' expression. However, the gruesomeness of an inverted mouth is attenuated when eyes are shown below it (producing an inverted smiling face) which suggests that the location of other facial features can also influence the assignments of 'top'.
