The Cognitive Atlas Project - way cool stuff

Poldrack, R. A. (2010). Mapping Mental Function to Brain Structure: How Can Cognitive Neuroimaging Succeed? Perspectives on Psychological Science, 5(6), 753-761
Abstract
The goal of cognitive neuroscience is to identify the mapping between brain function and mental processing. In this article, I examine the strategies that have been used to identify such mappings and argue that they may be fundamentally unable to identify selective structure–function mappings. To understand the functional anatomy of mental processes, it will be necessary for researchers to move from the brain-mapping strategies that the field has employed toward a search for selective associations. This will require a greater focus on the structure of cognitive processes, which can be achieved through the development of formal ontologies that describe the structure of mental processes. In this article, I outline the Cognitive Atlas Project, which is developing such ontologies, and show how this knowledge could be used in conjunction with data-mining approaches to more directly relate mental processes and brain function.

The article , with annotations, is available here, as part of this blogs IQ's Reading feature.

Research Bytes: Neuro-imaging research--brain networks and public interest
Beck, D. M. (2010). The Appeal of the Brain in the Popular Press. Perspectives on Psychological Science, 5(6), 762-766.
Since the advent of human neuroimaging, and of functional magnetic resonance imaging (fMRI) in particular, the popular press has shown an increasing interest in brain-related findings. In this article, I explore possible reasons behind this interest, including recent data suggesting that people find brain images and neuroscience language more convincing than results that make no reference to the brain (McCabe & Castel, 2008; Weisberg, Keil, Goodstein, Rawson, & Gray, 2008). I suggest that part of the allure of these data are the deceptively simply messages they afford, as well as general, but sometimes misguided, confidence in biological data. In addition to cataloging some misunderstandings by the press and public, I highlight the responsibilities of the research scientist in carefully conveying their work to the general public.

McDonald, R. P. (2010). Structural Models and the Art of Approximation. Perspectives on Psychological Science, 5(6), 675-686
Structural equation models have provided a seemingly rigorous method for investigating causal relations in nonexperimental data in the presence of measurement error or multiple measures of putative causes or effects. Methods have been developed for fitting these very complex models globally and obtaining global fit statistics or global measures of their approximation to sample data. Structural equation models are idealizations that can serve only as approximations to real multivariate data. Further, these models are multidimensional, and the approximation is itself multidimensional. Tests of “significance” and global indices of approximation do not provide an adequate basis for judging the acceptability of the approximation. Standard applications of structural models use a composite of two models—a measurement (path) model and a path (causal) model. Separate analyses of the measurement model and the path model provide an informed judgment, whereas the composite global analysis can easily yield unreasonable conclusions. Separating the component models enables a careful assessment of the actual constraints implied by the path model, using recently developed methods. An empirical example shows how the conventional global treatment yields unacceptable conclusions

FYiPost: Malaria and IQ
From the always interesting MARGINAL REVOLUTION blog
The figure below, from Bill Gates's annual letter, shows that countries with a higher disease burden have lower average IQs. The theory is that building brains and fighting disease are metabolically costly so more effort to fend disease diverts resources from brain development lowering IQ.
Tyler blogged this research earlier writing "I'm not sure the authors have a very good test against alternative hypotheses, but still a correlation remains after making some appropriate adjustments."
Further evidence on causality is given by Atheendar Venkataramani in Early Life Exposure to Malaria and Cognition and Skills in Adulthood. Venkataramani finds that men born after widespread malaria eradication began in Mexico in the late 1950s have higher IQs (Raven scores) and are more likely to work in white collar jobs than men born shortly before eradication efforts began. Importantly, the effect is larger for men born in those states that began with high exposure to malaria.

Ga (auditory processing)--the adolescent social butterfly at the CHC intelligence theory ball
If Gc is the wallflower (Hunt, 2000) at the CHC ball, then Ga (auditory processing) is an adolescent social butterfly flitting from factor to factor, not readily defined or understood by others, and still in an awkward formative stage of adolescent theoretical and psychometric identity formation (with notable identity role confusion). Ga was the least studied factor in Carroll’s (1993) treatise, largely because reliable and valid technology for measuring Ga abilities did not exist during most of the days of prolific psychometric factor analytic research. This situation has been recently remedied by an explosion of wide ranging (but not necessarily internally coherent or organized research) on a wide array of Ga characteristics (see Conway, Pisoni & Kronenberger, 2009; Gathercole, 2006; Hubbard, 2010; Rammsayer & Brandler, 2007)
Conway, Pisoni and Kronenberger (2009) have gone as far as elevating auditory abilities to the status as a critical ability for higher level cognition and language development. Given the temporal/sequential nature of sound, these researchers suggest auditory abilities provide critical exposure to serially ordered events, “bootstrapping the development of sequential processing and behavior. Sound thus provides a ‘scaffolding”—a supporting framework—that organisms use to learn how to interpret and process sequential information” (p. 275). Thus, auditory abilities are believed to play a foundational causal role in the development of “perception, sensory-motor control, language, and higher level functions” (p. 278). Pretty heady stuff for the Ga social butterfly!
The possibility of components of Ga being crucial to cognitive development is reinforced by Rammsayer and colleagues (Helmbold, Troche, & Rammsayer, 2007; Rammsayer & Brandler, 2007) who have presented an intriguing program of systematic research that have suggested that auditory based temporal processing tasks form a temporal psychometric g-factor that is more strongly associated with psychometric g than a reaction time g-factor, the long considered holy grail essence of g.
Further reflecting the adolescent nature of our understanding of the Ga domain is the fact that auditory imagery, which according Hubbard (2010, p. 302) was defined by Intons-Peterson (1992, p. 46) as “the introspective persistence of an auditory experience, including one constructed from components drawn from long-term memory, in the absence of direct sensory instigation of that experience,” has a massive body of research literature—yet auditory imagery is nowhere to be found in the current CHC taxonomy. Hubbard's (2010) comprehensive review covers such wide ranging research as “(a) imagery for auditory features (pitch, timbre, loudness), (b) imagery for complex nonverbal auditory stimuli (musical contour, melody, harmony, tempo, notational audiation, environmental sounds), (c) imagery for verbal stimuli (speech, text, in dreams, interior monologue), (d) auditory imagery's relationship to perception and memory (detection, encoding, recall, mnemonic properties, phonological loop), and (e) individual differences in auditory imagery (in vividness, musical ability and experience, synesthesia, musical hallucinosis, schizophrenia, amusia).”
Additional examples of the emerging importance of Ga abilities, many not yet included in the CHC taxonomy, exist in other arenas. First, central auditory processing disorders (CAPD), which refer to “difficulties in the perceptual processing of auditory information in the auditory nervous system as demonstrated by poor performance in one or more of the following skill areas: auditory discrimination, auditory pattern recognition, temporal aspects of audition, auditory performance in competing acoustic signals, and auditory performance with de-graded acoustic signals” (DeBonis & Moncrieff, 2008, p. 4-5), are now recognized by professional associations serving speech-language pathologists and audiologists and have been linked to specific language disorders. Second, numerous studies have been studying performance on non- or pseudo-word repetition tasks, tasks that appear to measure a Ga conglomerate involving acoustic signal processing, phonological awareness and sensitivity, an apparent Glr-type phonological storage and recoding ability, and speech-motor planning (see review of Gathercole, 2006 for research findings and Archibald and Gathercole, 2006 for review of measures). Although the non-word repetition tests are most likely factorially messy, the resultant research begs for scrutiny given a meta-analysis of 34 studies that reported a significant difference (d = 0.65, N = 2865) between individuals with specific reading disabilities and matched control groups without a reading disability (Herrmann, Matyas & Pratt, 2006).
Third—and beyond. Research in Ga domains proliferates like mosquitoes on a humid summer evening in Minnesota, with research investigating rapid auditory gap detection (Stefanatos, Braitman, & Madigan, 2007) , speech perception and auditory temporal processing (Boets, Wouters, Van Wieringen, & Ghesquiere, 2007), rhythm perception and production (van Noorden & Moelansts, 2006), rhythm sensitivity (Holliman, Wood & Sheely, 2010), to name but a few. Clearly the domain of Ga is not well understood. Ga-related research is scattered across research labs, disciplines, and journals. It would be a huge task to integrate all the research. A clear understanding of the dimensional structural of the very broad Ga domain requires extensive factor analytic research.
If in doubt, I recently searched the IAP Reference Data Base and found over 1,600+ references that includes some form of "auditory" term in a journal title or keywords. Click here to view.
