Preregistration 101

By Geoff Cumming Posted on December 24, 2016 Posted in Open Science No Comments

Of all Open Science practices, researchers often find preregistration most strange, and perhaps most puzzling and challenging. Of the three Open Science badges, the Prereg badge is the rarest, at least so far. “Does it really make much difference?” “But …

By Bob C-J Posted on December 20, 2016 Posted in ITNS, NHST No Comments

“If my department switches to the new statistics, will this tank our majors’ scores on the Major Field Test, which our administration uses as an important assessment tool?” This was one of the first questions asked during a workshop Craig …

Clinical Psychological Science goes Open

By Geoff Cumming Posted on December 18, 2016 Posted in Open Science, Replication No Comments

Adopting Open Science poses challenges, which vary across fields of research. For example, it may be especially difficult to carry out replications in clinical psychology if participants with the needed clinical diagnosis are hard to find. But Scott Lilienfeld, the …

Get into the discussion – The Psych Methods and Practices Group on Facebook

By Bob C-J Posted on December 7, 2016 Posted in Open Science No Comments

Robert Ross pointed me towards PsychMAP, the Psychology Methods and Practices Discussion Group hosted on Facebook.  It’s a very strong group; you can easily become completely absorbed scrolling through the posts and responses. https://www.facebook.com/groups/psychmap/  

SIPS: Getting better all the time

By Geoff Cumming Posted on December 5, 2016 Posted in Open Science No Comments

The Beatles sang about “getting so much better all the time”. So perhaps Getting Better by Paul McCartney and John Lennon should be the theme song of Open Science? (Although some of the lyrics would need to be expunged…) Bob …

NHST: The double whammy!

By Geoff Cumming Posted on December 2, 2016 Posted in Applied research, NHST No Comments

When I gave a talk at the HFESA conference, I started of course with an example of the damage done by NHST. My chosen article describes three examples in the field of road safety of how reliance on statistical significance …

Open Data, Re-usable Code

By Bob C-J Posted on December 1, 2016 Posted in Open Science, Replication, Stats tools No Comments

It feels like every day there is a new development in the Open Science movement.  It’s overwhelming, but exciting.  Here’s a site that I only just stumbled on: Kaggle.  It provides high-quality curated data sets for statistical exploration.  It also …

What is (are) Human Factors?

By Geoff Cumming Posted on November 27, 2016 Posted in Applied research No Comments

One of the great things about working in statistics is that you can play in other people’s backyards. After all, just about every scientific discipline uses statistics. So I enjoyed giving an invited talk at the recent annual conference of …

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

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:

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
