Exam 6: Sensation and Perception

The dimension of auditory experience related to the intensity of a sound wave is called:

Sensation occurs in the ________, whereas perception occurs in the ________.

According to Gestalt psychologists, we always organize our visual field into figure and ground.

Americans pay more attention to context than do the Japanese.

Ganglion cells are neurons in the retina of the eye that gather information from receptor cells by way of bipolar cells.

The smallest difference in stimulation that can be reliably detected by an observer when two stimuli are compared is called:

The centre of the tongue contains no taste buds and cannot produce any taste sensation.

Liana is listening to CBC Radio when the satellite feed momentarily goes out. Despite the short interruption, she was able to understand the conversation. This would be an example of the Gestalt principle of:

The gate-control theory of pain states that the experience of pain depends, in part, on whether pain impulses get past a neurological "gate."

Which two senses keep us informed about the movement of our own body?

When we have an interest in something we are especially likely to perceive it.

The part of the eye that gives it colour is the:

In a signal-detection task, the participant says that she doesn't detect a signal and no signal was present. This is called a:

The most rare type of colour deficiency occurs when individuals are unable to distinguish red from green.

By studying absolute thresholds, psychologists have found that our senses are very sharp. If you have normal sensory abilities, you will be able to do all of the following EXCEPT:

The absence of normal levels of sensory stimulation is called:

Sound intensity is measured in units of measurement named after the inventor of the telephone, Alexander Graham Bell. What are these units called? Contrast the typical sound levels associated with several different environments. How can exposure to loud noises damage hearing?

Homer notices that his favourite 99-cent bag of chips seems lighter than usual and so he checks the label and finds that it is lighter by 15 grams. He decides to buy a larger bag instead and doesn't notice that the $1.49 bag also is lighter by 15 grams. Homer's behaviour illustrates the fact that:

If the auditory system did not detect differences in the intensity of sound waves, we would NOT be able to:

The gate-control theory helps to explain our perception of:
