b. perception
c. adaptation
d. cognition
e. conduction: a: sensation
2. Taste: 1 gram of table salt in 500 liters of water; smell: 1 drop of perfume

on your cheek from a height of 1 cm away. These are all examples of:
a. the just-noticeable difference of our senses
b. The difference threshold for our senses
c. The absolute threshold of our senses
d. The adaptation of our senses
e. The perception of our senses: c. The absolute threshold
3. Weber's law can best be defined as:
a. the smallest change in stimulation that can be detected 50% of the time.
b. The principle that the just-noticeable difference for any given sense is a
constant proportion of the stimulation being judged
c. The principle that there is an adjustment of sensation levels depending on
the stimulation received
d. the idea that the least amount of energy detected in a stimulation only
occurs 50% of the time.
e. the theory that all stimuli respond to the same sensations through the
process of creating meaningful patterns.: b. the principle that the just
noticeable difference for any given sense is a constant proportion of the
stimulation being judged.
