A hackathon is an event, typically lasting for 24-48 hours, in which a group of people with diverse backgrounds come together to solve a problem by building a first working prototype of a solution (usually a web app, program or a utility).
There is something inherently likable, or dare I say, smart, about hackathons. They have a specific goal, your progress and results are measurable, getting a first working prototype is both achievable and realistic, and it will all be over in 24-48 hours. I have come to appreciate hackathons a lot over the last five months where I’ve participated in five, and won two of them with my teams. I would like to invite you to participate in one as well by giving you 7±2 tips to make your hackathon experience especially enjoyable. Continue reading
With a reliable internet connection comes access to the enormous World Wide Web. Being so large, we rely on tools like Google to search and filter all this information. Additional filters can be found in sites like Wikipedia, offering a library style access to curated knowledge, but it too is enormous. In more recent years, open online courses has rapidly become a highly popular method of gaining easy access to curated, high quality, as well as pre-packaged knowledge. A particularly popular variety is the Massive Open Online Course, or MOOC, which are found on platforms like Coursera and edX. The promise – global and free access to high quality education – has often been applauded. Some have heralded the age of the MOOC as the death of campus based teaching. Others are more critical, often citing the high drop-out rates as a sign of failure, or argue that MOOCs do not or cannot foster ‘real’ learning (e.g., Zemsky, 2014; Pope, 2014). Continue reading
Programming is a skill that all psychology students should learn. I can think of so many reasons on why, including automating boring stuff, and practicing problem solving skills through learning to code and programming. In this post I will focus on two more immediate ways that may be relevant for a Psychology student, particularly during data collection and data analysis. For a more elaborated discussion on the topic read the post on my personal blog: Every Psychologist Should Learn Programming.
Here is what we will do in this post:
- Basic Python by example (i.e., a t-test for paired samples)
- Program a Flanker task using the Python library Expyriment
- Visualise and analyse data Continue reading
Do you wish to publish your work but don’t know how to get started? We asked some of our student authors, Janne Hellerup Nielsen, Dimitar Karadzhov, and Noelle Sammon, to share their experience of getting published. Continue reading
Bayesian statistics is what all the cool kids are talking about these days. Upon closer inspection, this does not come as a surprise. In contrast to classical statistics, Bayesian inference is principled, coherent, unbiased, and addresses an important question in science: in which of my hypothesis should I believe in, and how strongly, given the collected data? Continue reading
If you have gone through the trouble of picking up a copy of the Publication Manual of the American Psychological Association (APA, 2010), I’m sure your first reaction was similar to mine: “Ugh! 272 pages of boredom.” Do people actually read this monster? I don’t know. I don’t think so. I know I haven’t read every last bit of it. You may be relieved to hear that your reaction resonates with some of the critique that has been voiced by senior researchers in Psychology, such as Henry L. Roediger III (2004). But let’s face it: APA style is not going anywhere. It is one of the major style regimes in academia and is used in many fields other than Psychology, including medical and other public health journals. And to be fair, standardizing academic documents is not a bad idea. It helps readers to efficiently access the desired information. It helps authors by making the journal’s expectations regarding style explicit, and it helps reviewers to concentrate on the content of a manuscript. Most importantly, the guidelines set a standard that is accepted by a large number of outlets. Imagine a world in which you had to familiarize yourself with a different style every time you chose a new outlet for your scholarly work. Continue reading
Why should you attend Summer Schools?
To put it simply: there is no better way to learn about psychology (and related disciplines), to travel, and to meet new people, all at the same time! Summer schools offer the opportunity to explore areas of psychology that might not be taught at your university, or to really explore a subject, seeing as this scheme allows you to focus your work on one topic in the company of students who are enthusiastic about the same subject. Last year, I attended a summer school on Law, Criminology and Psychology – coming from Germany, where Criminology is in the Law faculty, that was my opportunity to learn more about eye-witness accounts, lie detection, psychopathy, and how to interrogate children. Aside from classic lectures, summer schools often include seminars and group work. Continue reading
APA-guidelines, don’t we all love them? As an example, take one simple black line used to separate words – the hyphen: not only do you have to check whether a term needs a hyphen or a blank space will suffice, you also have to think about the different types of hyphens (Em-dash, En-dash, minus, and hyphen). Yes, it is not that much fun. And at JEPS we often get the question: why do we even have to adhere to those guidelines?

The answer is rather simple: The formatting constraints imposed by journals enable for the emphasis to be placed on the manuscript’s content during the review process. The fact that all manuscripts submitted share the same format allows for the Reviewers to concentrate on the content without being distracted by unfamiliar and irregular formatting and reporting styles.
The Publication Manual counts an impressive 286 pages and causes quite some confusion. In JEPS, we have counted the most frequent mistakes in manuscripts submitted to us – data that the EndNote-blog has translated into this nice little graphic.
Here you can find some suggestions on how to avoid these mistakes in the first place.

There is a revolution in statistics happening: The Bayesian revolution. Psychology students who are interested in research methods (which I hope everyone is!) should know what this revolution is about. Gaining this knowledge now instead of later might spare you lots of misconceptions about statistics as it is usually instructed in psychology, and it might help you gain a deeper understanding of the foundations of statistics. To make sure that you can try out everything you learn immediately, I conducted analysis in the free statistics software R (www.r-project.org; click HERE for a tutorial how to get started with R, and install RStudio for an enhanced R-experience) and I provide the syntax for the analysis directly in the article so you can easily try them out. So let’s jump in: What is “Bayesian Statistics”, and why do we need it? Continue reading
