It has been a while, but we’re happy to present the last two parts of Page’s R course. In this lesson we will learn how to run a LMEM (linear mixed effects model). We will also introduce the packages RColorBrewer and lme4, and as always expanded your knowledge of dplyr and ggplot2 calls.
For full materials, see the course website for Lesson 6, Part 1.
Here you can revisit Lesson 0, Lesson 1, Lesson 2, Lesson 3, Lesson 4 , and Lesson 5.
Dear CogTales reader, this post is about and made possible by you! You made this year the best yet in this little blog’s history. In today’s post, we want to take a moment and review which five posts you were most interested in. But first, we want to thank you. We’re hoping that you continue to come back and maybe even tell a friend or two about us. You can even contribute, if you have a story you would like to share, either with your name or anonymously, just get in touch.
So now let’s take a look back at the year as it is ending and review the top five posts according to our visitor statistics in 2017. Continue reading Looking back on 2017
Sometimes, things just fall into place: The evening before the most recent Academic Crisis Line on dealing with rejection and frustration, I got a pre-holiday manuscript rejection. As pointed out by the crisis liners, rejection in academia happens to everyone on a rather regular basis. So what we should really be concentrating on is to deal with it in the most self-preserving and productive ways possible. One thing that can really help is to talk through it, and to connect with others in similar situations.
So I thought it would be an interesting experiment to share my unfiltered thoughts while I deal with this rejected paper here on this blog.

Just a few months ago, I moved into the very first office that has only my name on it. During my whole scientific career, I shared offices of various sizes with between 1 and 7+ people. My office history ranges from the windowless undergrad thesis internship room where 6 students working on related projects and shared science and cookies over the room with a view and 2 colleagues as a PhD to the office with a server and between 0 and 3 others I occupied as post doc. During this time, I experienced many ways of sharing space: From the uncomplicated folks that tolerate your occasional cursing at the monitor to the weirdly expansion obsessed colleague who insisted that I would have more room if I just moved closer to the wall. Now, I’d like to think I know a bit about how to navigate shared office spaces, and I want to impart some bits of my wisdom and open them for discussion. Don’t hesitate to share your office mate horror stories in the comments and/or add useful tips how to improve office life!
One argument that often comes up when I talk to skeptics of preregistration is that it stands in the way of creative and exciting research. I couldn’t disagree more. Preregistration and registered reports are among the very best developments that have come out of Psychology’s replication crisis. Both guide a way towards better research. But since the sentiment that preregistration and creativity are not compatible is so prevalent and seems so genuine (as opposed to being an excuse to engage in questionable research practices), I do want to expand on some main reasons why preregistration does not dampen creativity in research. Continue reading Why we don’t need to be afraid that preregistration prevents creativity
This month, we are celebrating the anniversary of Germany’s reunification. This event is very important to me, as it reminds me every year, together with the anniversary of the fall of the Berlin wall in November, how lucky I am to be able to live the international scientist nomad life. Although this lifestyle with short term contracts has a lot of downsides, it is also a unique opportunity to work with various amazing people and follow your curiosity and ambition where it takes you.
