Like human infants,kittens are born with the ability to detect horizontal lines and vertical lines.In one famous study,kittens were exposed to either vertical or horizontal black and white stripes.Special collars kept them from seeing anything else,even their own bodies.In what way did the results of this study contribute to an understanding of critical periods in development? What evidence do we have of critical periods for sensory development in human beings?

The _______________ is a measure of the smallest amount of energy a person can reliably detect.

When measuring absolute threshold,reliable detection is said to occur when a person can detect a signal 99 percent of the time.

When deficits in the sense of smell have been studied,it has been found that smokers
