Eye contact provides a communicative link between humans, prompting joint attention. As spontaneous brain activity might have an important role in the coordination of neuronal processing within the brain, their inter-subject synchronization might occur during eye contact. To test this, we conducted simultaneous functional MRI in pairs of adults. Eye contact was maintained at baseline while the ...

Popular belief holds that eye contact increases the success of persuasive communication, and prior research suggests that speakers who direct their gaze more toward their listeners are perceived as more persuasive. In contrast, we demonstrate that more eye contact between the listener and speaker during persuasive communication predicts less attitude change in the direction advocated. In Study ...

purpose : acanthamoeba keratitis (ak) is a sight-threatening corneal infection with a rapidly increased incidence since 1990s along with the growing popularity of contact lenses. in this study we aimed to study patients with ak and its associated risk factors in farabi eye hospital of tehran, focusing on those with more severe corneal involvement. methods : patients with clinical or laboratory ...

This study investigated whether eye contact perception differs in people with different cultural backgrounds. Finnish (European) and Japanese (East Asian) participants were asked to determine whether Finnish and Japanese neutral faces with various gaze directions were looking at them. Further, participants rated the face stimuli for emotion and other affect-related dimensions. The results indic...

Background: Dry eye symptoms are more frequent in contact lens wearers than in non wearers. Dry eye is considered relatively common in contact lens wearers than non-wearers. However, there was no any report in our clinical setting that compared and addressed the issue related to dry eye and its symptom in contact lens wearers. The present study was conducted to compare pre-ocular tear film in c...

Previous research suggests that closing one's eyes or averting one's gaze from another person can benefit visual-spatial imagination by interrupting cognitive demands associated with face-to-face interaction (Markson and Paterson, 2009). The present study further investigated this influence of social gaze on adults' visual-spatial imagination, using the matrix task (Kerr, 1987, 1993). Participa...

The Keeler Pulsair non-contact tonometer was compared with the Goldmann applanation tonometer in a series of 48 eyes after operation. A correlation coefficient of 0.92 (p less than 0.001) was found between the two instruments, with the Pulsair having a statistically significant tendency to overread the Goldmann slightly in this situation. The Pulsair was, however, shown to be effective in the i...

This paper describes a simple yet effective method for achieving accurate, believable eye contact between humans and computer-generated characters, which to the author’s knowledge is demonstrated here for the first time. A prototype system provides a high-fidelity stereoscopic head-tracked virtual environment, within which the user can engage in eye contact with a nearphotorealistic virtual hum...

Contact lenses provide safe and effective vision correction for many Americans. However, contact lens wearers risk infection if they fail to wear, clean, disinfect, and store their contact lenses as directed. Over the past decade, CDC has investigated several multistate outbreaks of serious eye infections among contact lens wearers, including Acanthamoeba keratitis. Each investigation identifie...
