What is the Cross-modal oddball paradigm?

My current research focus on how attention can be captured by deviating stimuli. I will briefly describe the paradigm I have used – the cross-modal oddball task. Before I go into the cross-modal oddball task I will describe the auditory oddball task. In the oddball paradigm the subjects are exposed to a repetitive stream of […]

Python script for trial randomization

In this post you will find a Python script for randomizing conditions with constraints (i.e., never 2 consecutive trials of X). This script will in a later post be implemented in a cross-modal oddball task created in Psychopy. I recently started to use Psychopy to build experiments. To build my experiments (mainly oddball tasks) I […]
