visual magnitude
2.To generate a desirable mission catalog,a novel method of the automatic selection of guide star,the regression selection algorithm,was presented in this paper. With the creation of distribution function of the dynamic visual magnitude threshold (VMT), the static VMT in the traditional visual magnitude filtering method was replaced by the dynamic VMT.
3.Weldon and Coyote (1996) postulated the visual distinctiveness hypothesis to account for the picture superiority effect in explicit memory, while Hamilton and Rajaram (2001) argued that conceptual processing was greater in magnitude during imaging than during the encoding of concrete words, so imaging enhanced conceptual priming but concrete words did not.
