Which of the following is true? The absolute threshold for any stimulus is a constant. The absolute threshold for any stimulus varies somewhat. The absolute threshold is defined as the minimum amount of stimulation necessary for a stimulus to be detected 75% of the time. The absolute threshold is defined as the minimum amount of stimulation necessary for a stimulus to be detected 60% of the time.

The absolute threshold for any stimulus varies somewhat.

Sensory adaptation is beneficial because it allows us to focus our attention on informative changes in the environment without being distracted by uninformative constant stimulation. [1 pts.] True False

True

Which of the following is an example of sensory adaptation? [1 pts.] finding the cold water of a swimming pool warmer after you have been in it for awhile developing an increased sensitivity to salt the more you use it in foods becoming very irritated at the continuing sound of a dripping faucet witnessing a wolf attack and then being afraid of a chihuahua all of the choices are correct

finding the cold water of a swimming pool warmer after you have been in it for awhile

When admiring the texture of a piece of fabric, Jess usually runs her fingertips over the cloth's surface. She does this because [1 pts.] if the cloth were held motionless, sensory adaptation to its feel would quickly occur. the sense of touch does not adapt. a relatively small amount of brain tissue is devoted to processing touch from the fingertips. the sense of touch enhances the sense of vision. all of the choices are correct

if the cloth were held motionless, sensory adaptation to its feel would quickly occur

A decrease in sensory responsiveness accompanying an unchanging stimulus is called [1 pts.] sensory fatigue. accommodation. sensory adaptation. sensory interaction.

sensory adaptation

After constant exposure to an unchanging stimulus, the receptor cells of our senses begin to fire less vigorously, this phenomenon is called [1 pts.] threshold difference. sensory adaptation. psychophysics. subliminal messages. priming effect.

sensory adaptation.

Some people believe that ________ are messages that can be sent to consumers, prompting them to buy a product without their being aware of receiving such messages. [1 pts.] below threshold perceptions selective perceptions adjusted threshold perceptions subliminal stimuli inductive perceptions

subliminal stimuli

absolute threshold

The point at which a person can detect a stimulus 50 percent of the time it is presented is called the ________. [1 pts.] range threshold noticeable threshold absolute threshold change threshold difference threshold

absolute threshold
