Psychometric curves for natural image discrimination. (a) During the testing blocks, mice were presented stimulus pairs of SSIM indices between 0.074 and 1 in random order, allowing us to sample the full range of SSIM indices for each animal. The same pairs were shown repeatedly to generate accurate estimates of the correct rate for each data point. Psychometric curves were fit to the data. The SSIM threshold (vertical dotted line; percent coherence at 70% accuracy) was computed from the fitted curves. (b) The psychometric curves from the five mice were similar. (c) SSIM threshold of five mice. The position of circles along the x-axis was shifted to avoid obscuring them due to overlap. The SSIM thresholds for the five mice were also very similar. (d) Each data point shows mean ± S.E.M. for each distractor image across all five mice. The psychometric curve is for the averaged data (threshold = 0.30). Note that for some distractors (e.g., #5, #9, and #11), the correct rate was not accurately approximated by the psychometric curve.
