Exam 3: Sensation and Perception

Sensation is the brain's and the sense organs' sorting out,interpretation,analysis,and integration of stimuli.

Sensation encompasses the processes by which our sense organs receive information from the environment.

Some of the most basic perceptual processes can be described by a series of principles that focus on the ways we organize bits and pieces of information into meaningful wholes.

Explain why our senses are extremely responsive to stimuli,utilizing the concept of absolute threshold.

_______________ is the movement of air molecules brought about by a source of vibration.

When light energy strikes the rods and cones,it triggers a neural response that moves out of the back of the eyeball and into the brain through a bundle of ganglion axons called the _______________.

The theory that suggests that receptor cells are linked in pairs,working in opposition to each other,is known as the _________________ theory of color vision.

The range of wavelengths that humans are sensitive to is called the visual scope.

The theory that suggests that receptor cells are linked in pairs,working in opposition to each other is known as the _________________ theory of color vision.

Physical stimuli that consistently produce errors in perception are known as __________.

_____________ encompasses the processes by which our sense organs receive information from the environment.

_________ is background stimulation that interferes with the perception of other stimuli.

According to the gate control theory of pain,particular ______ receptors in the spinal cord lead to specific areas of the brain related to pain.

The ability to view the world in three dimensions and to perceive distance is a skill known as _______________.

What are skin senses and what role do they play in survival?

The sense of taste differs significantly from one person to another,largely as a result of genetic factors.

Perception is the brain's and the sense organs' sorting out,interpretation,analysis,and integration of stimuli.

A stimulus is any passing source of physical energy that produces a response in a sense organ.

The movement of an object across the ________ is typically perceived relative to some stable,unmoving background.

Absolute threshold is the largest amount of intensity that must be present in order for an object to appear to the human eye.
