________ is the science of quantitative relationships between physical and psychological events

_________ is a psychological method in which a particular dimension of a stimulus, or the difference between two stimuli, is varied incrementally until the participant responds differently (i.e. measures just noticeable differences)

__________ is the method of limits for which the subject controls the change in stimulus. This is the least accurate, because it is difficult to have the subject reliably adjust the stimulus the same definition threshold across trials (i.e. measure the average error)

• low; apex; medium; base
• low; apex; high; base

• high; apex; medium; base
• medium; middle; high; base
