A good time to remind people that 1) not all deviations from a preregistration are equally problematic for the severity of a test, and 2) if you need to deviate, deviate. The validity of the test trumps its severity. online.ucpress.edu/collabra/art...

If you analyse time-resolved data (M/EEG, iEEG, pupillometry, force recordings…) and feel limited by cluster-based permutation tests (CBPTs); especially when trying to determine when an effect starts or ends; you may want to try our new R package: lnalborczyk.github.io/neurogam/ #rstats #brms #EEG

Instead, better tone identification was predicted by pitch acuity. This suggests that domain-general auditory processing―not universal phonological principles―is a more important determinant.

Typology of traps, how they can be avoided, and what goes wrong if not avoided. Note that all traps in a sense constitute category errors (Ryle & Tanney, 2009) and the success-to-truth inference (Guest & Martin, 2023) is an important driver in most, if not all, of the traps.

right! mgcv can fit a binomial AR(1) model, but it's a little particular... you have to use bam() with discrete=T, for example (which, in turn, this precludes using something other than fREML)

Interesting! We do fit a logistic GAMM with (temporal) autocorrelation... but we don't address the spatial autocorrelation at all. In any case, I think it's compatible? Our innovation is using posterior simulations to obtain a temporal CI, but there is some freedom in terms of the model building.

We formally evaluate a popular bootstrap-based method (Stone et al., 2021) and find that it can produce delayed estimates and inflated type I error rates. We propose a novel GAMM-based method that allows more accurate comparison of onsets between experimental conditions and/or speaker groups.
