Neural efficiency and general intelligence: Is it mental quickness or timing?

Today I made a post at IM-HOME discussing the neural efficiency = general intelligence hypothesis (Arthur Jensen) where I make the case that recent research suggests that temporal or timing g (the internal brain clock) is a more fundamental cause of neural efficiency than the dominant Jensen reaction time g hypothesis. Check it out.

Mad Box reaction time app: Possible brain fitness tool?

An interesting reaction time app for the iPhone/iPad. It has the appearance of a possible brain fitness tool......would be nice someone would do some research on this to see if it does improve any aspects of cognitive functioning

Jensen's Clocking the Mind: Another book review

I've previously posted two reviews of Arthur Jensen's "Clocking the Mind" book. I just found a third review (click here to view). Readers now have three different reviews of this high profile book in the field of intelligence research.

Jensen's "Clocking the Mind" book reviews

I purchased a copy of Jensen's "Clocking the Mind: Mental Chronometry and individual differences" and it has sat on my pile of "to read" publications for a good year. So...I have no first-hand knowledge from which to render a review. However, other reviews are now becoming available. Click here for prior post regarding a review at the DI blog.

Two reviews (one quite positive; the other more negative) are now "in press" in the journal Intelligence. Check out Detterman's review and a review by Wagenmakers.

Brain clock = g (general intelligence)?

[Double click on image to enlarge]

Check out intriguing post at my sister blog (the IQ Brain Clock) re: another study that suggests that temporal processing (temporal g) may be more related to psychometric intelligence/g than the classic reaction time g paradigm.

Book review. Jensen's Clocking the Mind

The first available review that I've seen of Arthur Jensen's recent book, Clocking the Mind, has just been posted at the Developing Intelligence blog. Take a peak. I do know that formal journal published reviews of this work are in the works (click here).

IQ, skew and reaction time measurs of general intelligence

A thought provoking Developing Intelligence post (stimulated by Chris Chatham, the DI blogmaster, reading of Jensen's "Clocking the Mind" regarding "IQ & Skew, or why not to log-transform RTs (reaction times)."

Primarily for those interested in the statistical handling of cognitive reaction time measures.
