Four experiments assessed preferences for schematic faces. In Experiment 1, eye gap and nose width were manipulated separately, and effects of shifting the range of values were assessed. Descriptive ratings of width showed contrast effects in accordance with A. Parducci's (1995) range-frequency theory. Evaluative ratings of pleasantness showed reversals of preference ordering that were modeled ...

The Shack-Hartmann wavefront sensor (SHWS) spots upon which ocular aberration measurements depend have poor quality in mice due to light reflected from multiple retinal layers. We have designed and implemented a SHWS that can favor light from a specific retinal layer and measured monochromatic aberrations in 20 eyes from 10 anesthetized C57BL/6J mice. Using this instrument, we show that mice ar...

The aim of the present study was to investigate whether the biological relevance of the stimulus could enhance taskirrelevant spatial information delivered by a pair of bilateral stimuli. Participants had to perform a Simon-like task in which they were required to respond to the color of two framed squares (on and off-centered), two framed arrows, or two schematic eyes by pressing one of two ke...

Two visual world eye-tracking studies investigated the effect of emotions and actions on sentence processing. Positively emotionally valenced German non-canonical object-verb-subject (OVS) sentences were paired with a scene depicting three characters (agent-patient-distractor) as either performing the action described by the sentence, or not performing any actions. These scene-sentence pairs we...

The aim of this note is rst to set up some general theory for discussing diierent aspects of the notion of a logic and then to draw attention to the schematic aspects of logic and suggest a way of capturing this aspect without making any commitment to the kind of syntax a logic should have.

Measurement of ocular wavefront aberration is becoming a popular clinical technique due to recent technical advances and an increasing awareness of its potential for practical application in the fields of surgical and optical refractive correction. In addition, information about the status of peripheral refraction determined from ocular wavefront aberrations is now being used to monitor the pro...

We describe a computer eye model that allows for aspheric surfaces and a three-dimensional computer-based ray-tracing technique to simulate optical properties of the human eye and visual perception under various eye defects. Eye surfaces, such as the cornea, eye lens, and retina, are modeled or approximated by a set of Zernike polynomials that are fitted to input data for the respective surface...

The present study investigates how people's voluntary saccades are influenced by where another person is looking, even when this is counterpredictive of the intended saccade direction. The color of a fixation point instructed participants to make saccades either to the left or right. These saccade directions were either congruent or incongruent with the eye gaze of a centrally presented schemat...
