Table 1.

Summed rating frequencies over ensemble size and old/new test items. Standard equal-variance estimates of model parameters are shown on the right (μ1 = mean of the signal distribution, σ1 = standard deviation of the signal distribution, m = slope of the isosensitivity function, and da is a standard estimate of memory sensitivity).
