Here we explored nonverbal actions women use to flirt competitively against each other for the purposes of accessing a mate. We also investigated perceived effectiveness these competitive flirting actions. Using act nomination, Study 1 (n = 91) yielded 11 (eye contact with man, dancing in his line sight, smiling at him, touching giggling jokes, butting between woman and showing distaste her, br...

Using a micropolarographic system, we measured the responses of six human corneas to nine oxygen exposure conditions: to air (continuous open-eye) with no contact lens in place, and to eight interblink intervals (1, 2, 3, 4, 5, 6, 7, and 300 s durations) with an oxygen impermeable lens in place. The corneal oxygen uptake rates immediately following each of those conditions were direct indices o...

Background and Aims: Amoebae of the genus Acanthamoeba are unicellular amphizoic opportunistic pathogens that may cause fatal granulomatous encephalitis, eye keratitis, amebic pneumonitis and skin nodules as well as abscesses in humans and animals. Acanthamoeba keratitis is caused by trauma to the eye, contaminated cleaning solutions and the use of contact lenses. The aim of the present study w...

During a dyadic social interaction, two individuals can share visual attention through gaze, directed to each other (eye contact) or to a third person or an object (joint attention). Eye contact and joint attention are tightly coupled to generate the state of shared attention across individuals. Hyperscanning fMRI conducted with pairs of adults during joint attention tasks showed interindividua...

Observing eye contact between others enhances the tendency to subsequently follow their gaze and has been suggested to function as a social signal that adds meaning to an upcoming action or event. The present study investigated effects of observed eye contact in high-functioning autism (HFA). Two faces on a screen either looked at or away from each other before providing congruent or incongruen...

PURPOSE To explore the relationships among length of contact lens (CL) wear, degree of corneal staining and severity of dryness symptoms, and to determine whether these relationships differ between Asians and non-Asians. METHODS Adapted soft CL wearers (n=395; 180 Asian, 215 non-Asian) were required to discontinue CL wear for at least 24h and report to the University of California, Berkeley C...

A system to measure the topography of the first optical surface of the human eye noninvasively by using a curvature sensor is described. The static corneal topography and the dynamic topography of the tear film can both be measured, and the topographies obtained are presented. The system makes possible the study of the dynamic aberrations introduced by the tear film to determine their contribut...
