Oh but pictures of brains with colored parts just screams science! http://www.ncbi.nlm.nih.gov/pubmed/17803985 Seeing is believing: the effect of brain images on judgments of scientific reasoning McCabe DP ( http://www.ncbi.nlm.nih.gov/pubmed?term=%22McCabe%20DP%22%5BAuthor%5D ), Castel AD ( http://www.ncbi.nlm.nih.gov/pubmed?term=%22Castel%20AD%22%5BAuthor%5D ). Abstract Brain images are believed to have a particularly persuasive influence on the public perception of research on cognition. Three experiments are reported showing that presenting brain images with articles summarizing cognitive neuroscience research resulted in higher ratings of scientific reasoning for arguments made in those articles, as compared to articles accompanied by bar graphs, a topographical map of brain activation, or no image. These data lend support to the notion that part of the fascination, and the credibility, of brain imaging research lies in the persuasive power of the actual brain images themselves. We argue that brain images are influential because they provide a physical basis for abstract cognitive processes, appealing to people's affinity for reductionistic explanations of cognitive phenomena.

There does seem to be a fascination with these brain findings, and many of them merely point to a general area of the brain, which may be a first step but clearly not a complete "explanation." Though I am a sucker for these too. In my Mind, Brain, Evolution class I mention the role of the temporal lobes in creating out-of-the-body experiences and other spiritual phenomenon, but that's not a complete "explanation." And brain areas NOT lighted up will surely by a part of the explanation. Speaking about fMRIs, I don't know if I posted this on tips before, but if not, here is a link to the now-famous story about the brain activity of a dead salmon: http://lawandbiosciences.wordpress.com/2009/09/18/what-a-dead-salmon-reminds-us-about-fmri-analysis/ >From this blog: "In short, researchers scanned a dead fish while it was “shown a series of photographs depicting human individuals in social situations. The salmon was asked to determine what emotion the individual in the photo must have been experiencing.”" I heard George Wolford give a talk to students at last years New Hampshire Psych Association meetings about this story. The research study was NOT about the social cognition of dead salmon; if memory serves they were calibrating/fiddling with the fMRI at Dartmouth and one of the grad students stuck his soon-to-be dinner in the tube and detected brain activity to social stimuli. What was going on was the way the fMRI crunched the data, making the equivalent of thousands of statistical comparisons. Holy Type I error!! ========================== John W. Kulig, Ph.D. Professor of Psychology Director, Psychology Honors Plymouth State University Plymouth NH 03264 ========================== ----- Original Message ----- From: sbl...@ubishops.ca To: "Teaching in the Psychological Sciences (TIPS)" <tips@fsulist.frostburg.edu> Sent: Thursday, March 31, 2011 8:31:05 AM Subject: [tips] Neurobabble The Huffington Post (of all places!) has a nice piece today on " The brain is not an explanation", based on an article in _Perspectives on Psychological Science_. It disputes the explanatory value of the now- ubiquitous brain scams (oops! I meant scans) in investigating brain and behaviour. http://tinyurl.com/4sz5x8t I would add two items to the article. First, that the term "pleasures centers of the brain" is itself a suspect abstraction, as we really have little hard evidence concerning such claims. Second, that not only is the analysis of fMRI data difficult and complex, but that often (as has been repeatedly noted), its statistical basis is questionable. Seek (without correcting for multiple statistical tests) and ye shall find. Stephen -------------------------------------------- Stephen L.
