Exam 6: Sensation and Perception

In signal detection tasks, yea-sayers will have more misses than naysayers.

When many frequencies are present but are not in harmony, we hear noise.

Frida is sitting on a park bench when she hears a police car turn on its siren. Although she cannot see the police car, she is certain that it is nearby. What cue did her brain most likely use to come to this conclusion?

Peripheral vision (side vision) is handled by the cones.

Visual receptors that are involved in color vision are called cones.

The rarest type of color deficiency occurs when individuals are unable to distinguish red from green.

The process by which rods and cones become more sensitive to light in response to lowered levels of illumination is called:

Which of the following forms of coding is described in Müller's doctrine of specific nerve energies?

When adults who have been blind from infancy have their vision restored, they are able to make sense of what they see within days.

The _______________ protects the eye and bends incoming light rays toward a lens located behind it.

Most people who chronically have trouble tasting things have a problem with smell, not taste.

The colored part of the eye is called the _______________.

Normally, kinesthesis and equilibrium work together to give us a sense of our own physical reality. But when they do not, the consequences are profound. What happens to patients whose kinesthetic nerve fibers are damaged irreversibly?

If the sensory nerves all use exactly the same form of communication (a neural impulse), how, then, do we experience so many different kinds of sensations?

When Mary looks at the following display, she tends to see horizontal rows rather than vertical columns of faces. This happens because:

The doctrine of specific nerve energies states that:

When an observer is moving, objects appear to move at different speeds and in different directions.

Which of the following physical characteristics of light is related to brightness?

A group of cells at the bottom of the cerebral cortex, just above the cerebellum, respond maximally to faces.

The receptors for vision, hearing, and taste are specialized cells separated from sensory neurons by synapses.
