Intro to Psychology: Sensation and Perception

Which of the following best defines sensation?

• The process of interpreting sensory information

• The way the brain organizes incoming stimuli

• The process of receiving stimuli from the environment

• The act of remembering past experiences

What is the process by which sensory information is converted into neural signals?

• Transmission

• Transduction

• Perception

• Sensory adaptation

Which sensory threshold refers to the smallest difference between two stimuli that can be detected 50% of the time?

• Absolute threshold

• Relative threshold

• Just noticeable difference (JND)

• Sensory adaptation

Which scientist developed the law of just noticeable differences?

• Gustav Fechner

• Ernst Weber

• Wilhelm Wundt

• John Watson

What does Weber’s Law state?

• The larger the stimulus, the greater the change needed for detection
  

• Sensory adaptation occurs over time

• The brain processes all stimuli equally

• Perception is subjective

What is the absolute threshold?

• The smallest difference between two stimuli detected 50% of the time

• The minimum amount of stimulus energy needed for detection 50% of the time

• The point at which perception begins

• The level of attention given to a stimulus

Which of the following is NOT an example of an absolute threshold?

• The faintest light a person can see in a dark room

• The softest sound a person can hear

• The smallest difference between two shades of blue a person can detect

• The minimum concentration of sugar in water a person can taste

Which of the following best describes habituation?

• The brain filtering out repetitive stimuli

• An increase in sensitivity to stimuli over time

• The process of transducing stimuli into neural signals

• The brain enhancing attention to important stimuli

Sensory adaptation occurs when:

• The brain ignores constant stimuli over time

• The senses become more sensitive to new stimuli

• The brain prioritizes certain stimuli over others

• Stimuli are too weak to be detected

Which of the following is an example of sensory adaptation?

• Feeling your clothes less after wearing them for a while

• Not noticing a clock ticking until someone mentions it

• Getting used to the smell of perfume over time

• All of the above
