Influences of prolonged viewing of tilted lines on perceived line orientation: the normalization and tilt after-effect.

29 Jun 2009 Gibson [J. Exp. Psychol. 16, 1 (1993)] observed that during prolonged viewing, a line perceptually rotates toward the nearest vertical or horizontal meridian (the normalization effect), and moreover, the perceived orientation of a subsequently ... Read more...

The psychophysics of chasing: A case study in the perception of animacy.

2 Jun 2009 Psychologists have long been captivated by the perception of animacy - the fact that even simple moving shapes may appear to engage in animate, intentional, and goal-directed movements. Here we report several new types of studies of a particularly ... Read more...

Illusory shadow person causing paradoxical gaze deviations during temporal lobe seizures.

30 May 2009 Generally, activation of the frontal eye field during seizures can cause versive (forced) gaze deviation, while non-versive head deviation is hypothesised to result from ictal neglect after inactivation of the ipsilateral temporo-parietal area. ... Read more...
