The video is totally worth a watch for everyone going to conferences and presenting at or attending poster sessions. The end result But why?

Working with soldiers

originally written for gsnmunich.wordpress.com I let my eyes wander along the front gate. The entrance to the University campus is closed and guarded.

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...
