Half of the subjects in the training phase of Experiment 1 named objects shown in a number
of orientations, whereas the other half named objects shown upright only. All subjects …

Two experiments, with 16 university students, revealed that errors of identification for
alphanumeric characters increased approximately linearly with increased angular deviation …

Abstract Effects of orientation on identification can be attenuated when other patterns at the
same (or a similar) orientation are identified in close temporal contiguity. In Experiments 1 …

Matching of simultaneously presented patterns with respect to shape regardless of
differences in size and orientation was investigated using reaction time methods. When a …

Past research has shown that speed of identifying single letters or digits is largely indifferent
to orientation, whereas the recognition of single words or connected text is markedly …

Abstract Effects of the spatial separation between 2 simultaneously presented random
patterns on the ability to determine whether the patterns are identical up to a translational …

Des sujets nommaicnt des lettres présentées selon quatre orientations (0, 60, 120, et 180)
aussi vite que possible. La performance d'identification était examinée pour les deux …

In Experiment 1, subjects made same-different judgments to pairs of shapes that could differ
(irrelevantly) in size and in which different pairs combined distinct shapes. Size discrepancy …

Recent studies have shown that response time in mental rotation increases with the angular
deviation between the current and preceding stimuli, suggesting a frame rotation process in …

Template theories of visual pattern recognition assume the operation of preprocessing
routines to deal with irrelevancies such as discrepancies in stimulus size. In three …
