Jung & Haier/Parieto-Frontal Integration Theory of Intelligence: BBS Call for Commentators

Below the proposal instructions please find the abstract, keywords, and a link to the full text of the forthcoming BBS target article: "The Parieto-Frontal Integration Theory (P-FIT) of Intelligence: Converging Neuroimaging Evidence" Rex E. Jung & Richard J. Haier This article has been accepted for publication in Behavioral and Brain Sciences (BBS), an international, interdisciplinary journal providing Open Peer Commentary on important and controversial current research in the biobehavioral and cognitive sciences. Commentators must be BBS Associates or suggested by a BBS Associate. To be considered as a commentator for this article, to suggest other appropriate commentators, or for information about how to become a BBS Associate, please reply by EMAIL by November 30, 2006 to: calls(a)bbsonline.org The Calls are sent to 10,000 BBS Associates, so there is no expectation (indeed, it would be calamitous) that each recipient should comment on every occasion! Hence there is no need to reply except if you wish to comment, or to suggest someone to comment. If you are not a BBS Associate, please approach a current BBS Associate (there are currently over 10,000 worldwide) who is familiar with your work to nominate you. All past BBS authors, referees and commentators are eligible to become BBS Associates. An electronic list of current BBS Associates is available at this location to help you select a name: http://www.bbsonline.org/Instructions/assoclist.html If no current BBS Associate knows your work, please send us your Curriculum Vitae and BBS will circulate it to appropriate Associates to ask whether they would be prepared to nominate you. (In the meantime, your name, address and email address will be entered into our database as an unaffiliated investigator.) ======================================================================= COMMENTARY PROPOSAL INSTRUCTIONS ======================================================================= ** VERY IMPORTANT ** To help us put together a balanced list of commentators, it would be most helpful if you would send us an indication of the relevant expertise you would bring to bear on the paper, and what aspect of the paper you would anticipate commenting upon. Please DO NOT prepare a commentary until you receive a formal invitation, indicating that it was possible to include your name on the final list, which is constructed so as to balance areas of expertise and frequency of prior commentaries in BBS. ======================================================================= *** TARGET ARTICLE INFORMATION *** ======================================================================= TITLE: The Parieto-Frontal Integration Theory (P-FIT) of Intelligence: Converging Neuroimaging Evidence AUTHOR: Rex E. Jung & Richard J. Haier ABSTRACT: "Is there a biology of intelligence which is characteristic of the normal human nervous system ...?" Here we review 37 modern neuroimaging studies in an attempt to address the questions posed by Halstead and other icons of the last century as they endeavored to understand how brain and behavior are linked through the expression of intelligence and reason. Reviewing studies from functional (i.e. functional Magnetic Resonance Imaging, Positron Emission Tomography) and structural (i.e. Magnetic Resonance Spectroscopy, Diffusion Tensor Imaging, Voxel Based Morphometry) neuroimaging paradigms, we report a striking consensus suggesting that variations in a distributed network predict individual differences found on intelligence and reasoning tasks. We describe this network as the Parieto-Frontal Integration Theory: P-FIT. The P-FIT includes, by Brodmann Areas (BAs): dorsolateral prefrontal cortex (BAs 6, 9, 10, 45, 46, 47), the inferior (BAs 39/40) and superior parietal (BA 7) lobe, the anterior cingulate (BA 32), and regions within the temporal (BAs 21, 37) and occipital lobes (BAs 18 & 19). White matter regions (i.e., arcuate fasciculus) are also implicated. The P-FIT is examined in light of findings from both human lesion studies, including missile wounds, frontal lobotomy/leukotomy, temporal lobectomy, and lesions resulting in damage to the language network (e.g., aphasia), as well as from imaging research identifying brain regions under significant genetic control. Overall, we conclude that modern neuroimaging techniques are beginning to articulate a biology of intelligence. We propose that the P-FIT provides a parsimonious account for many of the empirical observations to-date relating individual differences in intelligence test scores to variations in brain structure and function. Moreover, the model provides a framework for testing new hypotheses in future experimental designs.

BBS's new expanded page quota will make it possible for us to increase the number of books we treat per year, so this is an excellent time for BBS Associates and biobehavioral/cognitive scientists in general to nominate books you would like to see accorded BBS multiple book review. (Authors may self-nominate, but books can only be selected on the basis of multiple nominations.) It would be very helpful if you indicated in what way a BBS Multiple Book Review of the book(s) you nominate would be useful to the field (and of course a rich list of potential reviewers would be the best evidence of its potential impact!). *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* Please note: Your email address has been added to our user database for Calls for Commentators, the reason you received this email.
