There is clearly strong evidence for the primary role of processing speed (Gs) playing a indirect role on cognition mediated via working memory.- iPost using BlogPress from my Kevin McGrew's iPadintelligence IQ tests IQ testing IQ scores CHC intelligence theory CHC theory Cattell-Horn-Carroll human cognitive abilities psychology school psychology individual differences cognitive psychology neuropsychology neuroscience psychology special education educational psychology psychometrics psychological assessment psychological measurement IQs Corner general intelligence working memory executive function cognitive control processing speed working memory Gsm Gs aging cogni...

All my comments are embedded in the article as per the IQ's Reading feature of IQ's Corner. A very thought provoking article that ties together a wide array of research on attention, working memory (attentional control), the importance of brain network synchrony (esp. the P-FIT model of Haeir et al), etc.Worth the read. I particular like the treatment of working memory as more an attentional control mechanism and the treatment of cognitive control and top-down vs bottom-up attention.- iPost using BlogPress from my Kevin McGrew's iPadintelligence IQ tests IQ testing IQ scores CHC intelligence theory CHC theory Cattell-...

The abstract, initial CFA/SEM model, and the final CFA/SEM model are presented below. The initial model was not found plausible due to significant multicolinearity between a number of the measures (variance from some measures could be perfectly predicted from other tests, either singly, or in linear combination with other measures). Most intriguing conclusion for me is the clear importance of executive functioning (very broadly operationalized in the final model) for beginning writing.

A. (2010). Mapping Mental Function to Brain Structure: How Can Cognitive Neuroimaging Succeed? Perspectives on Psychological Science, 5(6), 753-761AbstractThe 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.

Why? Because I have been actively involved in reading research to better understand cognitive performance (working memory and executive attention in particular), the IQ Brain Clock (role of mental timing in human performance), and neuro-technology interventions (e.g., Interactive Metronome) that seem to improve cognitive efficiency. Across these different strands of research I have CONSTANTLY run across a number of common factors. In particular, I am constantly finding the dorsolateral pre-frontal cortex (PFC) as being critical to cognitive efficiency (working memory and cognitive processing speed), which in turn impacts intellectual functioning, especially Gf or fluid reasoning. The same brain area is implicated in mental timing and I...

As mentioned frequently at two of my blogs, I believe that controlled executive attention is one of the key cognitive dimensions in intellectual performance, particularly as it relates to working memory and executive function efficiency. I further have hypothesized that many of the current neuroscience based brain-fitness/training programs may all share a common element in their success--they all may fine-tuning controlled executive attention.With the above in mind, I found the following quote of interest in a general self-help book I just started reading...yes, at times, I find reading such books useful and informative.

The study sample consisted of a regionally representative cohort of 104 children followed prospectively from ages 2 to 6 years. At age 4, children completed a battery of executive function tasks that assessed planning, set shifting, and inhibitory control. Teachers completed the preschool version of the Behavior Rating Inventory of Executive Function. Clinical and classroom measures of children's mathematical achievement were collected at age 6. Results showed that children's performance on set shifting, inhibitory control, and general executive behavior measures during the preschool period accounted for s...

I don't have the time, or maybe the neural efficiency, to read, digest, integrate, and summarize a wave of recent research articles dealing with the concept of neural efficiency (oscillations) and intelligence.

However, much criticism has questioned the utility of this test as a marker of prefrontal function. A critical review of clinical studies suggests that the original WCST does not distinguish between frontal and non-frontal lesions. Likewise, functional neuroimaging studies confirm that delivery of negative feedback during WCST rule transitions activates a widespread network of frontal and non-frontal regions within a split-second time scale. New methodological and conceptual advances from theory-guided experimental designs, precise spatial and temporal sampling of brain activity, and modern integrative models of prefrontal function (Miller, 2000) combined wit...

I'm now 32. It was February 11, 2005. I had gone in looking for the diagnosis, but I definitely wasn't prepared for it to be confirmed! I came home with mixed feelings. Did the diagnosis change who I was? Did it matter? What should I do next?Well, I went to my GP with my papers and all; since I'd been diagnosed by a psychologist, I needed the GP to prescribe my medication. He stonewalled me (wanted to refer me to a psychiatrist, said, "You've waited this long, you can wait a little longer"), even though the medication I was looking at was Concerta, which is notoriously difficult to abuse!I changed doctors.I was put on 36mg Concerta, once a day, to start.

In their article, Pamela Smith of Radboud University Nijmegen, and colleagues Nils B. Jostmann of VU University Amsterdam, Adam Galinsky of the Kellogg School of Management at Northwestern University, and Wilco W. van Dijk of VU University Amsterdam, focus on a set of cognitive processes called executive functions. Executive functions help people maintain and pursue their goals in difficult, distracting situations. The researchers found that lacking power impaired people’s ability to keep track of ever-changing information, to parse out irrelevant information, ...

She is also a writer, and we were discussing our current projects at one point.This friend is currently working on a novel and five short films (22 minutes each).I am working on the second draft of a YA novel, the first draft of a movie, and the first draft of a general fiction novel. I'm also working on a Mass, but that's music and we were talking about literary work, so I didn't mention it.My friend expressed some wonder at how methodical I am. The fact that I "just do it" when it comes to my writing is, I guess, something that is difficult to understand.
