Grid-texture mechanisms in human vision: Contrast detection of regular sparse micro-patterns requires specialist templates

Data from a study in which we measured detection thresholds for periodic patterns with different Mark:Space ratios. Each block of data in the spreadsheet contains raw staircase data (number of correct trials and total number of trials at a range of contrast levels) for four repetitions of a single condition. Threshold and slope values for each repetition are also given.
