Send Telegram Notifications to your Mobile from Python/OpenSesame

Sending Telegram notifications might be very useful for receiving status messages, for example about participants performance during an experiment (see on the right). Getting this to work is remarkably easy – from a coding perspective. You will need around 10minutes to set up the bot prior to this. Te beauty is, you do not have to install any additional software...

Can we learn to ignore objects in our visual field?

When we look through our visual environment, we often get distracted. Can we learn to overcome this distraction and if yes how does it work? In our everyday life, we search all the time. We spend a lot of time searching for our keys, our reading glasses or a subway stop. Visual searches are the most prominent task our visual system...

Testing the “ELF emmit: Mind & Body Assistant” – The Science

This article is also available in video form on Youtube. Hi, I’m Marian, a Psychology/Neuroscience Researcher at the LMU Munich in Germany specializing in the topic of visual attention. I have personally used all methods described below. With its tagline “almost magic”, the ELF emmit sounds promising, indeed. Accordig to their website, it can be used to “Improve focus, sleep, meditation...

R – Exclude entire subjects if they lack data in one condition

It can sometimes be tricky to find out and eliminate participants that produce missing data in an analysis of interest. Most often you want to do an ANOVA with 2-3 factors and you receive the error message “One more more cells are missing data”. This happens when not all variables are experimentally controlled but are subject to the participants performance. For example, you...

Creating a 37-item circular visual search display with OpenSesame inline scripts

In this post I am going to explain how you can create a visual search display for a compound visual search task with an additional singleton that can either be singled out by color or orientation. The display has multiple items arranged in concentric circles. At the bottom there is the full code included in a working OpenSesame example. There is nothing...

The single reason for why basic research is important

People, like me, who are doing basic research, get often asked about how our basic science research can be applied. Most of the time, we don’t know. Nobody knows. Maybe someday we will, maybe we won’t. This is not important. Why not? Imagine you suddenly wake up naked in a rocky, sandy place, in the middle of nowhere. It’s really hot and you start...

Excessive Video Game Playing Linked to Generalized Anxiety Disorder – A Large-Scale Investigation of Gaming, Attitudes and Anxiety (2)

The (slightly filtered) dataset underlying this post has been released publicly on PsyArxiv. If you want me to do more analyses, please contact me any time. You can do them yourself, too, of course! This is part 2. Re-read part 1 here. I finally took the time to get into the data and do the first analyses for which I used the...

Is the dress black-blue or white-gold? Color constancy in the wild

Social media reactions exploded over the picture of a dress a couple of hours ago. The question seems simple enough but turned out tricky: Is this dress white and gold or blue and black? The colors seem incredibly different and initially I thought this was some kind of a social media joke. But apparently people were really not agreeing on...
