Important new IQ Brain Clock theory. Cassenti's motor-temporal link model of temporal cognition

I just read a very important new article that presents an alternative model for understanding temporal cognitive and motor processing. As written about in many posts at this blog, the two dominant theories to explain temporal processing (aka, IQ Brain Clock) are the neural oscillator and internal pacemaker models. Cassenti (2011) presents an interesting new model called the motor-temporal link model that places major emphasis on the intrinsic timing mechanisms present in over-learned stored motor sequences.

For those interested in the Interactive Metronome (see my conflict of interest disclosure statement), Cassenti uses the positive results of IM studies to provide support for his model

The abstract is below (double click to enlarge). Also, I have made additional comments in the body of a PDF copy of the article via the IQ's Reading feature of my different blogs. Click here to read the original article with my comments.

I have also added Dr. Cassenti to the Mental Scholars Blogroll and have also included this article in the Key Research Articles Blogroll section of this blog.

NIF Data Spotlight: Extensible Neuroimaging Archive Toolkit (XNAT)

"A picture is worth more than a thousand words". This idea applies to neuroscience and emphasizes the importance of visualization in science. With one image, it is possible to easily extract information and data that can take many words and tables to describe. XNAT, Extensible Neuroimaging Archive Toolkit is an open source imaging informatics platform designed to facilitate management and exploration of medical imaging and related data.

Cup-o-Joe favors extraverts working memory--give me an extra shot! You can sleep when you are dead

Smillie, L. D., & Gokcen, E. (2010). Caffeine enhances working memory for extraverts. Biological Psychology, 85(3), 496-498

Using a randomized double-blind placebo-controlled design we examined the effects of caffeine on working memory (WM) as a function of extraverted personality. Participants (N = 59) received 200 mg of caffeine and placebo in counterbalanced-order over two sessions prior to completing a ‘N-Back’ WM paradigm. Findings revealed that caffeine administration relative to the placebo condition resulted in heightened WM performance, but only for extraverted participants. We suggest based on previous theory and research that dopamine function (DA) may be the most plausible mechanism underlying this finding

Subject: FYiPost: Good heart beat perception = good temporal processing?

What underlies our sense of time? A popular account claims an internal pacemaker emits regular pulses, which are detected by an accumulator. The amount of accumulated pulses represents the amount of time that's passed.

Trouble is, this is all very theoretical and no-one really knows how or where in the brain these functions are enacted. One suggestion is that the pulses are based on bodily feedback and in particular the heart-beat. Consistent with this is a recent brain imaging study that showed activity in the insular (a brain region associated with representing internal bodily states) rose linearly as people paid attention to time intervals (pdf). Now a behavioural study by Karin Meissner and Marc Wittmann has built on these findings by showing that people who are more sensitive to their own heart-beat are also better at judging time intervals.

Research byte: Why working memory training programs work

Excellent overview article on the different types of working memory training programs and why some (core training programs) produce positive effects across different human performance domains and why the effects generalize. The core training programs appear to improve the domain-general mechanisms involving in working memory, such as controlled executive attention and disinhibition (ability to focus and screen out distractors). The focus on the frontal-parietal network (dorsolateral prefrontal cortex, posterior parietal cortex, the striatum, and the basal ganglia) has been a constant thread thru recent working memory theoretical and applied training research.

Morrison, A. B., & Chein, J. M. (2011). Does working memory training work? The promise and challenges of enhancing cognition by training working memory. Psychonomic Bulletin & Review, 18(1), 46-60


Abstract

A growing body of literature shows that one’s working memory (WM) capacity can be expanded through targeted training. Given the established relationship between WM and higher cognition, these successful training studies have led to speculation that WM training may yield broad cognitive benefits. This review considers the current state of the emerging WM training literature, and details both its successes and limitations. We identify two distinct approaches to WM training, strategy training and core training, and highlight both the theoretical and practical motivations that guide each approach. Training-related increases in WM capacity have been successfully demonstrated across a wide range of subject populations, but different training techniques seem to produce differential impacts upon the broader landscape of cognitive abilities. In particular, core WM training studies seem to produce more far-reaching transfer effects, likely because they target domain-general mechanisms of WM. The results of individual studies encourage optimism regarding the value of WM training as a tool for general cognitive enhancement. However, we discuss several limitations that should be addressed before the field endorses the value of this approach.
