Notes: c - specificity parameter, k -criterion parmeter, w - attention weight and λ, response exponent. TxB - Task x Block, T - Task, B - Block, F - Fixed across task and block. M – number of parameters, -lnL - Negative log-likelihood, BIC - Bayesian Information Criterion.
The best fitting model (i.e., lowest BIC) is shown in bold.
