Ryan Catalani on 07 Dec 11"Sustained changes in the region of the brain associated with cognitive function and emotional control were found in young adult men after one week of playing violent video games ... The results showed that after one week of violent game play, the video game group members showed less activation in the left inferior frontal lobe during the emotional Stroop task and less activation in the anterior cingulate cortex during the counting Stroop task."

Lisa Stewart on 09 Dec 11Several Words students were looking for such a study. I am interested in finding a version of the emotional stroop test that is used.

Ryan Catalani on 11 Dec 11Here's some basic information about the Stroop test they used, but I can't find anything more detailed: "During fMRI, the participants completed 2 modified Stroop tasks. During the emotional Stroop task, subjects pressed buttons matching the color of visually presented words. Words indicating violent actions were interspersed with nonviolent action words in a pseudorandom order. During the counting Stroop task, subjects completed a cognitive inhibition counting task." - http://www.medscape.com/viewarticle/754368

Ryan Catalani on 11 Dec 11Actually, there are some studies just about emotional Stroop tests that sound similar to the one in the violent video games study. This looks like a good presentation about how emotional Stroop tests work: http://frank.mtsu.edu/~sschmidt/Cognitive/Emotion1.pdf This one talks about why those Stroop tests work: "In this task, participants name the colors in which words are printed, and the words vary in their relevance to each theme of psychopathology.The authors review research showing that patients are often slower to name the color of a word associated with concerns relevant to their clinical condition." - http://brainimaging.waisman.wisc.edu/~perlman/papers/stickiness/WilliamsEmoStroop1996.pdf This is a meta-analysis of emotional Stroop test studies that describes (actually, it's critical of) how such studies are done: http://www.psych.wustl.edu/coglab/publications/LarsenMercerBalota2006.pdf

Lisa Stewart on 11 Dec 11Thanks, Ryan! I will take a look at these.
