Figure 5. Illustration of standardized betas derived from regressions including skin conductance responses (SCRs) (A) and fear ratings (B) for all data specifications.

Colored cells indicate statistical significance of standardized betas, non-colored cells indicate non-significance. Standardized betas are color coded for their direction and magnitude showing positive values from yellow to red and negative values from light blue to dark blue. Darker colors indicate higher betas. On the y-axis, the following data specifications are plotted from left to right: CS type, ranking of the data and transformation of the data. On the x-axis, the following information is plotted: Number of the columns for better orientation, predictor, and criterion included in the regression. For example, the beta value at the top left in (A) (i.e., 0.196) is the standardized beta as retrieved from the linear regression including CS discrimination in non-ranked and raw SCRs during average acquisition as predictor and the first extinction trial as criterion. For exploratory non-preregistered regressions including a small manyverse of approximations of SCR extinction training learning rates, see Figure 5—figure supplement 1. Tables containing regression parameters beyond the standardized betas depicted in panels A and B are presented in Supplementary file 7 and Supplementary file 8. AVE = average, LOG = log-transformed data, LOG.RC = log-transformed and range corrected data, not ordinal = not ordinally ranked data, ordinal = ordinally ranked data.

Figure 5—figure supplement 1. As per reviewer’s request, we illustrate standardized betas derived from non-pre-registered regressions including skin conductance response (SCR) extinction training learning rates (LR EXT).

As there is no agreed upon approach, we provide a small manyverse of approximations of extinction learning rates. We subtracted (1) the last extinction trial from the first extinction trial (i.e., for CS discrimination during the first and last trial, for CS+ and for CS−, respectively; LR EXT 1, columns 1–3), (2) the last two extinction trials from the first two extinction trials (LR EXT 2, columns 4–6), (3) the last quarter of trials from the first quarter of trials (i.e., four trials; LR EXT 4, columns 7–9), and (4) the last half from the first half of trials (i.e., seven trials; LR EXT H, columns 10–12). We acknowledge that learning rates have been inferred through different approaches in the literature (see e.g., Ney et al., 2020; Ney et al., 2022) and are often calculated from model-based approaches such as Rescorla Wagner Model (Seel, 2012) and hence our operationalizations are only four out of multiple equally justifiable options. Colored cells indicate statistical significance of standardized betas, non-colored cells indicate non-significance. Standardized betas are color coded for their direction and magnitude showing positive values from yellow to red and negative values from light blue to dark blue. Darker colors indicate higher betas. AVE = average, LOG = log-transformed data, LOG.RC = log-transformed and range corrected data, not ordinal = not ordinally ranked data, ordinal = ordinally ranked data.
