Making pre-registration work

By Bob C-J Posted on August 28, 2016 Posted in Uncategorized No Comments

Here is link to the COMPARE project, an incredible, though depressing, project designed to check if clinical trials are following their preregistered analysis plans when published. Pre-registration is a great technique to help draw a bright line between planned and …

Criminal justice and the perils of regression analysis

By Bob C-J Posted on August 2, 2016 Posted in Uncategorized No Comments

Regression analysis is incredible–it can literally help us predict the future based on patterns observed in the past. There are many pitfalls, however, to using regression. First, the correlations observed in the past may not apply to new cases or …

A great example of how you can prove negligible effects and why it is so important to do so. Otherwise, how would we ever identify boundary conditions or refine theories? @adamcchang

Is this the greatest article title ever?

Some studies do replicate, including this interesting association between mathematical operations and body position (+ to the right, - to the left). Plus this paper has a detailed tutorial on a Bayesian analysis of a factorial design in JASP. Is +/right universal?

Just posted to @PsyArXiv -- a new paper with my students Keelyn Brennan and Michaela Rutledge:

"Arithmetic operation signs elicit spatial associations: A confirmatory Bayesian analysis"

If you teach ugrad science, this paper has something for you: https://tinyurl.com/juliopaper

Though focused on neuroscience, it:
* summarizes research on good science pedagogy
* explains why good teaching alone is not enough to confront discrimination
* tells admin how to support us

Because everything that can happen in 2020 does happen, a squirrel joined my stats zoom yesterday (from a 2nd floor window!)

If my students remember one thing about this semester, it will now probably be this squirrel. Wish I had somehow connected it to a stats concept.

Dear rec letter portal developers:

Who approved adding the "end of knowing" date field?

Is this because I am writing letters from the afterlife? That would make sense, because it feels like I am in hell.

In the physical sciences, you never use a piece of equipment without knowing its measurement range.

Hilgard shows how to do this in psychology. With a "Maximal Positive Control" you max out your behavioral assay, providing valuable context for interpreting regular results. 👍

Joe Hilgard, that psych prof we all know and love.@JoeHilgard

Some effect sizes are way too big to be true. But how can you demonstrate that they are too big to be true? With the method demonstrated in my newest article!

Well-powered, preregistered tDCS studies rarely find effects. I've lost all faith in this stimulation modality for psychological and behavioral outcomes. https://twitter.com/hersenprofessor/status/1327614868137111552

Maarten 💉 Frens 🇪🇺@hersenprofessor

We find no effect of tDCS on cortical excitability in a pre-registered, double-blind, randomized, placebo-controlled trial with repeated measures and sufficient power. Nor do we find evidence for so-called responders and non-responders https://www.brainstimjrnl.com/article/S1935-861X(20)30288-6/fulltext

What is forgetting? Is it decay of information, or just a temporary loss of access?

Today Irina and I published an experiment suggesting that forgetting is an access issue, at least for type of memory we studied. @SfNtweets
