Faces and bodies are both efficient in communicating emotions and attracting attention automatically. However, faces seem especially informative when seen in the near space, whereas bodies are particularly effective in the far space.

|Abstract (eng):||Faces and bodies are both efficient in communicating emotions and attracting attention automatically. However, faces seem especially informative when seen in the near space, whereas bodies are particularly effective in the far space.|
In the patient’s subgroup showing near-space neglect, a significant effect in reducing rightward bisection errors was found with both fearful and happy facial expressions presented in the near space, and with fearful and happy bodies presented in the far space. Conversely, in the patient’s subgroup showing far-space neglect, the most consistent reduction was observed for left-side fearful bodies shown in the far space. No significant effect was found with regard to healthy participants.
Fearful, happy and neutral facial or bodily expressions were used as lateral cues during a line bisection task. We studied 24 spatial neglect patients, 19 with a prevailing deficit in the near space and 5 with deficit in the far space. Besides, a 20 healthy participants group was recruited. Lines could be placed either near (60 cm) or far (150 cm) from the patients, who were asked to mask the midpoint regardless of the presence or nature of the lateral cues.
The present work bases on the available literature, showing that fearful and happy facial and bodily expressions may summon attention and overcome leftward bias in patients with hemispatial neglect. Here we tested the biologically-inspired hypothesis that faces are more effective than bodies in reducing neglect when presented in the near space, whereas bodily expressions are more effective when displayed in the far space.
