Revisiting the perception of upside-down faces

In two experiments, the effect of orientation on face perception was assessed. Using a scale from 1 ( normal ) to 7 ( bizarre ), participants rated normal, unaltered faces and faces in which changes had been made to spatial-relational properties (eyes and mouth inverted or relative position of the eyes and mouth altered) or to component properties (eyes whitened and teeth blackened). For unaltered and component-distortion faces, bizarreness ratings increased linearly as orientation increased from 0° to 180°. For spatial-distortion faces, a discontinuity in the function relating orientation and bizarreness was in evidence between 90° and 120°. The results provide support for the view that there is a qualitative difference in the processing of upright and inverted faces due to the disproportionate effect of inversion on the encoding of spatial-relational information.     

It’s not just average faces that are attractive: Computer-manipulated averageness makes birds,fish, and automobiles attractive

Average faces are attractive. We sought to distinguish whether this preference is an adaptation for finding high-quality mates (thedirect selectionaccount) or whether it reflects more general informationprocessing mechanisms. In three experiments, we examined the attractiveness of birds, fish, and automobiles whose averageness had been manipulated using digital image manipulation techniques common in research on facial attractiveness. Both manipulated averageness and rated averageness were strongly associated with attractiveness in all three stimulus categories. In addition, for birds and fish, but not for automobiles, the correlation between subjective averageness and attractiveness remained significant when the effect of subjective familiarity was partialled out. The results suggest that at least two mechanisms contribute to the attractiveness of average exemplars. One is a general preference for familiar stimuli, which contributes to the appeal of averageness in all three categories. The other is a preference for averageness per se, which was found for birds and fish, but not for automobiles, and may reflect a preference for features signaling genetic quality in living organisms, including conspecifics.     

Holistic processing of faces in preschool children and adults

Contrary to the encoding-switch hypothesis, recent research demonstrates that 6-year-olds do not rely solely on parts-based encoding to recognize upright faces. This research shows better recognition of face parts presented in the whole face than in isolation, indicating use of holistic encoding. The present study examined whether children younger than 6 years also recognize faces holistically. Four-year-olds, 5-year-olds, and adults were administered a part-whole face recognition task. Children below the age of 6 remembered parts from upright faces better when tested in the whole-face context than in isolation. This whole-face advantage did not occur when faces were inverted. Although children showed a smaller inversion decrement than adults and generally performed more poorly than adults, the different age groups showed similar patterns of performance, indicating that young preschoolers, like older children and adults, are able to recognize faces holistically.     

Quantitative Electroencephalography (QEEG) and Neuropsychological Syndrome Analysis

The ideographic, syndrome analysis and the nomothetic, standardized test battery approaches to neuropsychological assessment are compared and contrasted within the context of advances in noninvasive technology readily available for use within the examiner's office. By demonstrating the relative strengths and benefits of syndrome analysis, it is suggested that this approach provides a thorough and efficient method of neuropsychological assessment. Subsequently, the utility of an a priori hypothesis testing process approach as a critical technique in syndrome analysis will be supported. It will be proposed that QEEG procedures provide a useful method for further substantiating conclusions generated from a syndrome analysis approach to neuropsychological assessment. Two cases are described demonstrating the utility and flexibility of the QEEG as a confirmatory test of localization following syndrome analysis. In summary, the contributions that neuropsychologists make to the understanding of brain–behavior relationships may be strengthened by combining neuropsychological and neurophysiological assessment methods.
