Methods, applications, and findings in visual pattern masking
Methods, applications, and findings in visual pattern masking
This chapter reviews the major methods, findings, and applications of visual masking. It outlines the major assumptions supporting the rationale of visual masking, followed by six specific types of pattern masking methods and the associated characteristic results they generate, followed by applications of pattern masking to a variety of fields in visual cognition and the phenomenology of masking (how a stimulus being masked appears perceptually). Next, details of how methodological variations of the criterion contents adopted by an observer (e.g. judging the brightness vs. the shape of a target stimulus), variations of target and mask parameters (luminance, contrast polarity, duration, wavelength composition, location in the visual field), and variations of viewing the target and mask stimuli via the same or separate eye(s) affect experimental findings and their theoretical significance, are discussed. Finally, extensions of these topics to more recent, related spatiotemporal phenomena are covered.
