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 …
Ames Trapezoid Illusion: A New Model, Daniel Robert Kelly
Ames Trapezoid Illusion: A New Model, Daniel Robert Kelly
Dissertations and Theses
Current explanations for the Ames Trapezoid Illusion are based upon the the absence of cues: the illusion is said to occur at chance. A review of recent literature showed that: (a) the illusion varies in frequency as a function of target shape (b) that the dominant cue to reduce the frequency of the illusion is the variant in retinal height. Based upon the dominance of this cue a new model was presented. Following this model it was hypothesized that observers viewing partial rotation when the target produces the greatest difference in the retinal height of the ends would determine the …
