[Thésaurus HELB]:Optique:regardRésumé : Eye contact occurs when two animals look into each other's eyes in the same time. In human being, eye contact is a form of nonverbal communication and is thought to have a huge influence on social behavior. That is why we have such a beautiful profession : we don't want to hide these beautiful eyes and the prime reason for eye contact between a pair of (reflecting) window (glasses) Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Relations interpersonnellesRésumé : SIGNIFICANCE: Discriminating quickly where another person's gaze is directed is a key component of social interaction, as gaze direction conveys information about others' intentions (approach or avoidance) and shift in gaze is used in group conversation. This study shows that patients with glaucoma are delayed in their discrimination of gaze direction. PURPOSE: The purpose of this study was to investigate whether glaucoma affects the perception of gaze direction. METHODS: Twenty-four patients with open-angle glaucoma, 24 age-matched controls, and 20 young normally sighted controls were presented with faces displayed centrally for 200 milliseconds. The gaze could either be direct or averted, and the head could be a frontal view or a rotated view. Half of the participants in each group were asked to press a key only for faces with a direct gaze. The other half responded for a face with an averted gaze. The orientation of the head had to be ignored. RESULTS: Accuracy was greater than 90% correct for all three groups. We found no difference in performance between young and older controls, except for shorter response times for the frontal view than for the rotated face in young participants. Patients with glaucoma needed on average 140 milliseconds longer to decide if the gaze was averted than for the direct gaze, and they were less accurate than controls in perceiving the gaze as direct when the head was rotated. CONCLUSIONS: Patients with glaucoma often experience impaired vision due to a reduced sensitivity in central vision. Although lower central sensitivity had little effect on their ability to discriminate gaze orientation, they required on average 140 milliseconds longer than age-matched controls to perceive an averted gaze.

[Thésaurus HELB]:Optique:regardRésumé : SIGNIFICANCE: Individuals with left hemianopic field loss (HFL), especially with neglect history, may have greater difficulties than individuals with right HFL in judging the direction of another person's gaze.
PURPOSE: Individuals with HFL often show a spatial bias in laboratory-based perceptual tasks. We investigated whether such biases also manifest in a more real-world task, perception of mutual gaze direction, an important, nonverbal communication cue in social nteractions.
METHODS: Participants adjusted the eye position of a life-size virtual head on a monitor at a 1-m distance untilthe eyes appeared to be looking straight at them, or (2) the eyes were perceived to be no longer looking at them (to the right and left).
RESULTS: Participants with right HFL (n = 8) demonstrated a rightward error in line bisection but made gaze judgments within the range of normally sighted controls (n = 17). Participants with left HFL without neglect history (n = 6) made leftward errors in line bisection and had more variable gaze judgments; three had estimates of gaze direction outside the reference range. Four participants with left HFL and neglect history made estimates of gaze direction that were to the right of the reference range.
CONCLUSIONS: Our results suggest that individuals with left HFL, especially with neglect history, may have greater difficulties than individuals with right HFL in compensating for low-level spatial biases (as manifested in line bisection) when performing the more complex, higher-level task of judging gaze direction.
