Eye Contact Perception At Distances Up To Six Meters, Daniel L. Scarl
Eye Contact Perception At Distances Up To Six Meters, Daniel L. Scarl
Dissertations and Theses
Common experience suggests that most people can tell whether they are being looked at by another person who is about 8 m away. However, the results of past experiments, which used distances of no more than about 3 m, have implied that this cannot be done if the person looked at (Receiver) judges only by the iris-sclera configuration of the person looking (Sender). This is true even if eye contact is defined simply as identifying on-face gazes (FGs). It has been suggested that in everyday experience eye contact is accompanied by cues other than iris position, and that these non-iris-position …
Scotopic And Photopic Thresholds : A Dependent Variable For The Mccollough Effect, Marilyn Murphy
Scotopic And Photopic Thresholds : A Dependent Variable For The Mccollough Effect, Marilyn Murphy
Dissertations and Theses
Previous attempts to adequately evaluate orientation-specific colored aftereffects (Mccollough Effects) have thus far been unsuccessful in yielding quantitative measures of relative strengths of the effects. Similarly, little success has been shown in previous attempts to establish what level of illumination is necessary in order to evoke the aftereffects. The present study sought to determine (a) whether threshold measurements could serve as adequate, quantitative dependent variables of the Mccollough Effects, (b) whether photopic illumination was necessary in order to evoke the aftereffect. It was predicted that the greater the number of inspection trials, the dimmer the illumination level could be in …
