If anyone is interested in using WhisperX to transcribe speech, this tutorial is for you!! In this tutorial, I provide an easy-to-use pipeline where you will get a time-aligned transcript as a Praat TextGrid file, a TSV file, and a subtitle file🙌

Vital for understanding language disorders & improving diagnostics.👇

You are right. That's why I'm trying to develop a good understanding so that I can make my judgments! And your summer school really helped me understand stats better :)

Sho Akamine @shoakamine.bsky.social · Aug 17

I think it’d be a great addition! Especially because I saw recommendations against using BF due to its sensitivity to priors, so instead using CI or HDI for NHST. That’s why I got confused when I read the statement in your book. I’ll read more papers/books and try to get a full understanding on this

Sho Akamine @shoakamine.bsky.social · Aug 17

Thank you so much for all the recommended readings!!!

Sho Akamine @shoakamine.bsky.social · Aug 15

Thank you so much for the elaborate answer! It was very informative!!

I'm currently reading the paper. Thanks a lot for your suggestion!

Sho Akamine @shoakamine.bsky.social · Aug 14

Thank you for the response! I think one should reject the null in case 1 and fail to reject in case 2, although "0.0000001" is a tiny diff. I see the point here, but doesn't this issue apply to any discrete decisions based on continuous measures? Or would this be less of a problem for Bayes factor?

Sho Akamine @shoakamine.bsky.social · Aug 13

Please help me learn! I see people using CI for hypothesis testing (whether 95% CIs for slope cover 0), but Nicenboim, Schad &Vasishth say in their fantastic book that "just by looking at the [CIs], we cannot make inferences about whether a null hypothesis can be rejected". Why is this the case?

Our conversation analysis software is now on CRAN! Reach out with any questions. We hope it’s useful for all you language and social interaction folks out there.

CRAN Package Updates Bot @cranberriesfeed.bsky.social · Jul 22

New CRAN package ConversationAlign with initial version 0.2.0
#rstats
https://cran.r-project.org/package=ConversationAlign

CRAN: Package ConversationAlign

Imports conversation transcripts into R, concatenates them into a single dataframe appending event identifiers, cleans and formats the text, then yokes user-specified psycholinguistic database values to each word. 'ConversationAlign' then computes alignment indices between two interlocutors across each transcript for >40 possible semantic, lexical, and affective dimensions. In addition to alignment, 'ConversationAlign' also produces a table of analytics (e.g., token count, type-token-ratio) in a summary table describing your particular text corpus.

Children are incredible language learning machines. But how do they do it? Our latest paper, just published in TICS, synthesizes decades of evidence to propose four components that must be built into any theory of how children learn language. 1/

I see, good to know! I’ll try segmented regression and splines and see which one makes more sense for my data ;)

Sho Akamine @shoakamine.bsky.social · Jul 16

Yes, that’s exactly what I had in mind! Didn’t know that they are called segmented regression. Thanks for your reply😊

At this point, I might as well --
Here's an infographic showing different ways to include age as a predictor. The top shows two extremes, just as a plain old numerical predictor (imposes linear trajectory) vs. categorical predictor (imposes nothing whatsoever). And then three solutions in between!

Infographic illustrating different ways to model age.
First panel shows two "extreme" cases; including age as a linear numerical predictor (df = 1) or including age as a categorical predictor (df = number of years of age minus 1).
Second panel shows an intermediate solution in which age is categorized into broader bins (df = number of categories minus 1, here 5 - 1 = 4).
Third panel shows an intermediate solution in which age is included with a polynomial (df = degrees of freedom of the polynomial, here 4).
Fourth panel shows an intermediate solution in which age is modeled with the help of splines (df = degrees of freedom of the splines, here 4).

Sho Akamine @shoakamine.bsky.social · Jul 16

This is amazing!!! Would it also make sense to model age as a continuous predictor within different age bins? So instead of getting one point estimate (flat line) for the in-between solution, we would fit a regression line in each binned age so that the flat lines will follow the date better?

Are you at #ISGS2025 today? Come see my talk in the kinematics session! I'll present my PhD work validating dynamic time warping (DTW) as a measure of gesture form similarity with manual ratings. We show that DTW can be an efficient, useful proxy for gesture form similarity!

Excited to present at ISGS25 this Thursday morning in Nijmegen!
Together with @shariceclough.bsky.social , we’ll be sharing our work on the role of gesture in narrative recall across Alzheimer’s, MCI, and healthy aging.
Looking forward to great discussions! 💪🏻🧠🗣️
