approach gradient

the variation in the strength of a drive as a function of the organism’s proximity to its goal. For example, a rat’s goal-directed behavior increases in intensity as it nears its goal of food. The approach gradient appears less steep than the avoidance gradient. [originally proposed by Neal E. Miller]

morphometrics

n. the theory and technique associated with the physical measurement of living organisms and their component parts. Studies of size, shape, and structure are important not only in biology but also in neuropsychology and medical psychology. For example, researchers interested in morphometrics could study the form and structure of the brain in individuals who have various physical or psychological disorders. By contrast, psychometrics specifically focuses on the measurement of psychological phenomena.
