Dunnett’s multiple comparison test

a statistical method for assessing whether a control group is significantly different from each of several treatment groups. It is similar to the Dunn–Bonferroni procedure but not as stringent in that it does not require the significance level per comparison to be as small. The index of difference that is obtained from this test is called Dunnett’s t. [Charles W. Dunnett (1921–2007), Canadian statistician]

common region

a recently introduced gestalt principle of organization, stating that objects sharing a common bounded region of space appear to belong together and tend to be perceived as a distinct group. For example, animals in a fenced-in enclosure are more likely to be seen as a group than are the same distribution of animals arrayed in open space. Also called law of common region; principle of common region. [proposed in 1992 by U.S. psychologist Stephen E. Palmer (1948– )]
