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...

Purging of memories from conscious awareness tracked in the human brain

When being asked about the importance of memory most people would say that remembering something is good and forgetting something is bad. While this seems reasonable to believe about factual knowledge (f.e. information about places or names of persons), there are certainly cases where it is beneficial to not remember something. The most prominent example is amnesia after a traumatic...

We watch you while you sleep – neuroimaging of dreams

Revised essay by Marian Sauter for the application to the Axol Science Scholarship 2015/16 In the last decade, technology has made it possible to combine fMRI and EEG in one experiment while minimizing the artifacts that the two methods produce on each other when combined. This paved the way for combined studies, in this example for the purpose of studying...

Are we in power? The functional neuroanatomy of intentional action

In his talk at the LMU Munich in April 2013, Marcel Brass gives an account of the functional neuroanatomy of intentional control of action. Since he found previous neuroanatomical evidence to be contradictory, he developed a new model decomposing intentional action into what, when and whether components (Brass & Haggard, 2008). Aside from his model, he talks about preconscious determinants...
