Weber"s law - the difference threshold (or jnd) is directly proportional to the magnitude of the stimulus with which the comparison is being made. Sensory adaptation - (habituation) the diminishing sensitivity to a constant stimulus over time. Survival value attend to new stimuli in the environment.
