Though they did not control the initial stages of dark adaptation (e.g., the first 5 minutes), the second or later part of the darkness adaptation curve (e.g., after 5 minutes) is determined specifically by the functioning of the __________.

How do animal studies of restricted stimulation and human studies of restored vision illustrate the important role of critical periods for perceptual development?

You are examining the sensory systems of a new species and notice a lot of hair cells. You suspect that you are looking at the

The theory of pitch perception that argues that the nerve impulses triggered by a given auditory stimulus should match the pitch of that stimulus is called __________ theory.

Interpreting visual illusions is evidence of the work that our perceptual processes are performing under normal conditions. Visual illusions can be viewed as examples of

You are meeting some friends at a pub. You haven't been to this particular pub before but know they are sitting near a stage where some musicians will be playing. When you arrive, you hear a band playing a cover of a song you recognize and walk towards the music, finding your friends almost immediately. How did your sense of hearing accomplish the task of locating where the sound was coming from?

Which of the following would be classified as an example of nerve deafness?

The middle ear-consisting of the hammer, anvil, and stirrup-is responsible for which of the following?

During the process of dark adaptation, the receptors' sensitivity gradually increases because

Perhaps the most dangerous time of day to drive a car is twilight. The low levels of light at this time of day hinder our ability to see other cars. In fact, from what we know about the capabilities of the rods and cones in low illumination, the safest colour of car to be driving would be

What is the primary cue for motion perception? How is stroboscopic movement used in motion pictures and television?

The presence of afterimages and the ability of some people with red-green colour blindness to perceive the colour yellow were not consistent with which theory of colour?

Lisa is participating in a psychology experiment. She is seated in a dimly lit room and is told to look straight ahead at the blank screen. Lisa's task is to detect points of light as they appear on the screen, and Lisa will be paid $10 for every point of light she correctly detects. Several minutes into the experiment, Lisa is discouraged by how few light points she is seeing, so she changes her strategy and starts focusing off to the side of the screen rather than in the middle of the screen as she had been. Sure enough, by the end of the experiment, Lisa has enough money to buy the pizza for tonight's study group. Lisa's new strategy worked because

A participant in a signal detection study has the tendency to be bolder in her decisions regarding the presence of a target stimulus. As a result, she has more hits, but also has more false alarms. This example demonstrates how ____________ can affect ___________.

When someone is nearsighted then the term used is hyperopia?

The size of the __________ regulates the amount of light that enters the eye.

You are meeting some friends at a pub. You haven't been to this particular pub before but know they are sitting near a stage where some musicians are playing. When you arrive, you hear a band playing a cover of a song you recognize and walk towards the music, finding your friends almost immediately. Given that the band playing the song you recognized were not playing it exactly the same way as you were used to, and had never heard their version before, what helps explain how you were able to recognize it?

The human auditory system is capable of localizing sound direction using differences of _____________ between the two ears.

The Sonic guide device, which is used to provide new "eyes" to people with blindness, utilizes the sensory principles of

While afterimages are not adequately explained by the trichromatic theory of colour, they can be readily explained by ____________ theory.
