Franz has recently had a minor accident that resulted in temporary brain impairment. Franz parks his car and as he walks away, Franz can no longer identify the car the further away from it he gets. He says the car is not his because it is too tiny to be his. What perceptual rule is involved when Franz cannot identify the car?

You should be able to decide which "rule" is contributing to Franz's problem.
I hope this helps. Thanks for asking.
The perceptual rule involved in Franz's inability to identify the car is known as size constancy. Size constancy refers to the tendency of humans to perceive an object as maintaining its size, regardless of the distance from which it is being viewed. In this case, Franz's brain impairment seems to be affecting his ability to accurately perceive the size of the car.
To understand how size constancy works, it is important to consider the visual cues that our brain uses to perceive the size of objects. One such cue is known as relative size. When objects are at different distances from us, the size they project on our retina (the light-sensitive layer at the back of the eye) varies. However, our brain takes into account the perceived distance to adjust for this variation and maintains the perceived size of familiar objects relatively constant. In Franz's case, his brain impairment appears to disrupt this perceptual adjustment, leading to the mistaken perception that the car is too small as he moves away from it.
Understanding the underlying principles and neural processes behind size constancy and other perceptual rules can help us better understand how our brains process visual information and perceive the world around us.
