Perhaps Unidimensional Is Not Unidimensional [PDF]
Cognitive Science, 2012 AbstractMiller (1956) identified his famous limit of 7 ± 2 items based in part on absolute identification—the ability to identify stimuli that differ on a single physical dimension, such as lines of different length. An important aspect of this limit is its independence from perceptual effects and its application across all stimulus types.
