Lightness of an object under two illumination levels.

abstract：:Several recent studies have shown that the performance of a skill that involves acting on a goal object can influence one's judgment of the size of that object. The present study investigated this effect in an aviation context. Novice pilots were asked to perform a series of visual approach and landing manoeuvres in a...

We propose that the systematic error of direction discrimination found by Lorenceau et al (1993, Vision Research 33 1207 - 1217) can explain this illusion. The neural correlate of such a...
