Free viewing perceptual asymmetry for distance judgments: objects in right hemispace are closer than they appear.

Neurologically normal individuals demonstrate leftward biases in tasks of line bisection and judgments of brightness, numerosity, and size. Normals also report and demonstrate a right-sided bias when bumping into objects. Collectively, these results suggest that normals relatively neglect the right hemispace.

Lateral biases in assumptions of lighting position.

People presume that the light source in pictures comes from above, and there is some evidence that this phenomenon also demonstrates lateral biases. When investigators present multiple ambiguous stimuli or visually complex objects, people assume that the source of light is from above, and to the left. However, when single relatively simple stimuli are presented, this lateral bias is not readily observed.

Novel stimuli are negative stimuli: evidence that negative affect is reduced in the mere exposure effect.

Repeated exposure of a nonreinforced stimulus results in an increased preference for that stimulus, the mere exposure effect. The present study repeatedly presented positive, negative, and neutrally affective faces to 48 participants while they made judgments about the emotional expression. Participants then rated the likeability of novel neutrally expressive faces and some of these previously presented faces, this time in their neutral expression.
