In all three studies, event-related potentials were recorded in addition to behavioral performance measures. Accordingly, both behavioral and electrophysiological studies have suggested that human bodies might rather be processed configurally i. The N inversion effect is often thought to reflect disruption of configuration processing of either faces Itier et al. Prior studies have shown that both faces and human bodies may engage attention to a greater extent than other objects such as clothes and food Langton et al. Journal of Cognitive Neuroscience, 6, The first stage includes sensitivity to first order relational information, which specifies the spatial relation between facial parts. Nr were identical under high and low load for faces while no comparable effect was observed for either hands or houses.

Bodies capture attention when nothing is expected. It has to be noted that the present N reduction for inverted eyeless faces is in contrast to the results of Itier et al. However, IEs have been reported in both behavioral and electrophysiological research for human bodies Reed et al. Here, we used different highly heterogeneous categories such as houses, hands, human bodies and faces. Geometric distortions and the Nr brain response to stimulus repetitions. This increase of ERs when hands were presented as distractors could be due to systematic differences in contrast and luminance of hands compared to both faces and houses, possibly making it more difficult to recognize letters superimposed on hands. Recently, many researchers have shown that human bodies are a special category when compared with other objects such as houses, cars and so on.

It has been suggested that faces and human bodies can engage attention to a greater extent than other objects Langton et al. Inversion effects were separately investigated for intact human bodies and faces Exp.

However, larger late negative deflections seems to be elicited in situations of increased recruitment of attentional resources such as it should occur for distractor objects under low perceptual load in the present design. The Nr voltage maps for all categories. In principle, some motion cue within a body could erlärung explain the inversion effects that were found in the present experiments for intact and headless bodies.

The N is accompanied ehrrnwörtliche a positive deflection over the central medial regions see Fig. However, it is still unresolved if all of the three stages of configural processing according to Maurer et al.

However, in that study, the authors used cropped faces i. The increase in N amplitudes to houses could be caused by a degraded representation of the house under high load, evoking a certain degree of face selectivity for the houses.

Subjects were instructed to detect dissertaiton butterflies to ensure that participants attended to the probe presentation. In a sworn testimony from Breker’s de-nazification process the Jewish book publisher Peter Suhrkamp thanks Breker for saving his life.

International Journal of Psychophysiology, 55, Second, given that human bodies and faces cause similar inversion effects, I further hypothesized that these effects should occur under low, perceptual load but not high perceptual load. While eye selective neurons are inhibited in the context of upright faces, inversion eliminates the face context, causing the release of eye-selective neurons from inhibition.

ERPs are a non-invasive diseertation for measuring brain activity during cognitive processing and provide an important unu for revealing questions about how the human brain, normally processes information Picton et al.

However, in that study, the authors used cropped faces i. I think that both faces and bodies play an important role when presented in combination in social perception. The Nr was larger for repetitions using the same disssertation Schweinberger et al.

For instance, increasing negativities in the N amplitude are often observed for inverted compared to upright stimuli cf.

This result suggests the importance of the combined presence of faces and human bodies. One could speculate that a certain degree of holistic processing may initially be evoked by houses under high load only, when these stimuli are presented briefly mswhile under low load processing relies solely on the part-based mechanism, which may cause N increase under high load.

Turning configural processing upside down: Are faces “special” objects? The role of perceptual load in neglect: This component is larger for either faces or human bodies than other objects. Yin, and human bodies e.

Schweinberger has suggested that P may reflect earlier stages in face processing related to pictorial encoding. The effect of inversion on the encoding of normal and “thatcherized” faces. Attentional erklärungg and sensory competition in human vision: However, when attention was manipulated according to the perceptual load theory PLTexplicit recognition of faces is reduced under high perceptual load compared to low perceptual load Jenkins et al.
