#8
What is the term for the smallest difference between two stimuli that can be reliably detected?
Difference threshold
ExplanationDifference threshold is the minimum difference in stimuli required for detection.
#9
Who proposed the concept of the just noticeable difference (JND) in psychophysics?

ExplanationErnst Weber introduced the concept of JND, the smallest detectable difference between two stimuli.
#10
What is the term for the ability to maintain a constant perception of an object despite changes in sensory input?
Perceptual constancy
ExplanationPerceptual constancy is the ability to perceive objects consistently despite changes in sensory input.
#11
What is the process by which sensory receptors become less responsive to constant stimuli?
Sensory adaptation
ExplanationSensory adaptation refers to the decreased response of sensory receptors to a constant stimulus.
#12
Which psychophysical law states that the strength of a sensation is proportional to the logarithm of the stimulus intensity?
Fechner's Law
ExplanationFechner's Law describes the relationship between the intensity of a stimulus and its perceived strength.
#13
What is the term for the perception of two different stimuli as being identical or very similar in intensity?
Perceptual constancy
ExplanationPerceptual constancy refers to the tendency to perceive stimuli as constant despite variations in sensory input.
