Salience, feature perturbations and localization errors on targets and location standards.

Examined the concept of salience (ease of localization) in 4 experiments, using 43 undergraduates. A test of the relative salience of stimuli used in Exps 2–4 was conducted in Exp 1. Exp 2 showed that a designated target (an H or a column of Hs) was used as the standard against which the designated standard for localization (a line end) was judged when the former was more salient than the latter. Exp 3 showed that thin lines similar to those in Exp 2 were judged as shorter than they were, which suggests a mislocalization toward fixation. In Exp 4, when standards covered the entire display background, a single H (but not columns of Hs) was mislocalized toward fixation.
