Table 2.
The parameters for one fit of the ePTM for each participant, plus nested ePTM model test results on R2 values. The selected fit includes three Af terms and two σ terms, as this was predominately the best fit. The βU term is not listed because it is determined by using βM along with the angular difference between the templates (either 8° or 40°) and their standard deviation, σ. The subscript on the σ terms indicates the attention (cuing) condition. The extra subscript on the Af terms indicates the relevant set size. Aa terms are not listed (and are set to 1) because allowing them to vary did not significantly improve any fit. Tests are described in text. Values noted with asterisks (* or **) are significant at the 0.05 or 0.01 level.
