maybe she's a proponent of the bootstrap-based method... 🤔

João Veríssimo @jverissimo.bsky.social · Jun 16

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.

What makes lexical tones challenging for L2 learners? Previous studies suggest that phonological universals are at play... In our perceptual study, we found little evidence for these universals.

A gentle introduction to Bayesian statistics, with applications to bilingualism research

Bayesian analyses have been increasingly adopted in psychology and linguistics as an addition (or replacement) to traditional frequentist methods. However, Bayesian methods are not yet widely applied…

João Veríssimo @jverissimo.bsky.social · May 24

It's an intro to the foundational principles of Bayesian stats AND a practical tutorial on estimation and hypothesis testing using brms. I build up from simple regression to mixed-effects models.

NEW paper! 💭🖥️

“Combining Psychology with Artificial Intelligence: What could possibly go wrong?”

— Brief review paper by @olivia.science & myself, highlighting traps to avoid when combining Psych with AI, and why this is so important. Check out our proposed way forward! 🌟💡

osf.io/preprints/ps...

Table 1
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.

Interesting... Tried mgcv::rmvn() and mvnfast::rmvn(). Both seems to produce the same random numbers (with and without the perturbations in the cov matrix).

Remember when you first learned about genetics at school? All those fascinating examples of human traits that are each apparently determined by just a single gene? Time to check in on some of your favourites to see how they’re doing. 🧬🧵🧪 1/n

Four images to illustrate some prominent single-gene myths. Top left shows a photograph of a person deftly rolling their tongue into a U-shape. Top right shows a photograph of a person’s ear, highlighting the shape and features of the earlobe and cartilage. Bottom left shows a close-up photograph of a person’s eye, with a vivid blue colouration. Bottom right shows a photograph of a person poised to write with their left hand on the blank white page of a spiral-bound notebook.

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)

João Veríssimo @jverissimo.bsky.social · May 5

package in the works! for now, you can source "OnsetDetection_Functions_0.4.7.R" from here and see the get_onset() examples in the analyses of Studies 1 and 2: osf.io/9ethq/files/... (note that the function still has some limitations, e.g., it only handles 1 random factor)

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.
