Brain Connection columnists

brain-2.jpgBrain Connection is a quality website discussing developments in neuroscience and psychology, and one of its highlights is the monthly column section.

The columnist, currently Robert Sylwester, tackles a different topic each month, and aims to relate current findings in neuroscience to everyday life.

Although Sylwester’s column has a slight slant towards the educational applications of recent research, the topics are diverse enough to interest the most eclectic of readers.

Brain Connection as a whole is a hugely useful site, as it not only explains many principles of cognitive science in an accessible manner, but has lots of free-to-use resources online for anyone wanting to add graphics, animations or useful links to their own presentations.

Electronic voice phenomena: A history

evp_radio.jpg

The Fortean Times has published an online article about EVP, or electronic voice phenomena, the experience of hearing ‘voices’ in the background of sound recordings.

The author of the piece has experienced EVP and believes the sounds to be spirits of the dead trying to communicate through the static.

Whether you believe this explanation (or think that EVP is more likely due to apophenia) the article remains a fascinating description of the history of the phenomena, most associated with parapsychologist Konstantin Raudive.

Behavioural and Brain Functions journal

Open access journals are good. Not only do they mean that the copyright on publicly funded-research doesn’t end in the hands of private companies, and that scientists don’t have to pay to read their own research, but it also means that everyone can read scientific research as it is communicated directly by scientists to their peers. There aren’t that many open access journals in psychology, so it great to hear about Behavioral and Brain Functions is a new, open access journal from biomedcentral, edited by Terje Sagvolden. Well done guys

the emperor’s new paradigm

And to follow up on recent posts (here, and here) on evolutionary psychology there is a new review in the latest edition of Trends in Cognitive Sciences:

Evolutionary psychology: the emperor’s new paradigm
David J. Buller
Trends in Cognitive Sciences
Volume 9, Issue 6 , June 2005, Pages 277-283
Abstract
For some evolutionary psychology is merely a field of inquiry, but for others it is a robust paradigm involving specific theories about the nature and evolution of the human mind. Proponents of this paradigm claim to have made several important discoveries regarding the evolved architecture of the mind. Highly publicized discoveries include a cheater-detection module, a psychological sex difference in jealousy, and motivational mechanisms underlying parental love and its lapses, which purportedly result in child maltreatment. In this article, I argue that the empirical evidence for these ‘discoveries’ is inconclusive, at best. I suggest that, as the reigning paradigm in evolutionary psychology has produced questionable results, the evolutionary study of human psychology is still in need of a guiding paradigm.
