Drinking to distraction: Does alcohol increase attentional bias in adults with ADHD?

Roberts, Walter; Fillmore, Mark T.; Milich, Richard

Experimental and Clinical Psychopharmacology, Nov 28, 2011, No Pagination Specified. doi: 10.1037/a0026379

Abstract

1. Previous research has shown that social drinkers continue to show attentional bias toward alcohol-related stimuli even after consuming a moderate dose of alcohol. In contrast, little is known about how alcohol acutely affects attentional bias in groups at risk to develop alcohol-related problems, such as adults with attention-deficit/hyperactivity disorder (ADHD). Such individuals may show increased attentional bias following alcohol relative to nonclinical controls. The present study tested this hypothesis by examining acute alcohol effects on attentional bias in 20 social drinkers with ADHD and 20 social drinkers with no history of ADHD. Participants performed a visual-probe task after receiving the following doses of alcohol: 0.64g/kg, 0.32g/kg, and 0.0g/kg (placebo). Those in the ADHD group showed increased attentional bias under active alcohol doses, whereas attentional bias was similar across doses in the control group. Attentional bias predicted ad libitum alcohol consumption during a taste-rating session. This relation was observed only in the ADHD group. These findings indicate that an acute alcohol dose increases attentional bias in adults with ADHD. Further, attentional bias appears to be a predictor of ad libitum consumption in this group.

Visual temporal processing in dyslexia and the magnocellular deficit theory: The need for speed?

McLean, Gregor M. T.; Stuart, Geoffrey W.; Coltheart, Veronika; Castles, Anne

Journal of Experimental Psychology: Human Perception and Performance, Vol 37(6), Dec 2011, 1957-1975. doi:10.1037/a0024668

Abstract

1. A controversial question in reading research is whether dyslexia is associated with impairments in the magnocellular system and, if so, how these low-level visual impairments might affect reading acquisition. This study used a novel chromatic flicker perception task to specifically explore temporal aspects of magnocellular functioning in 40 children with dyslexia and 42 age-matched controls (aged 7–11). The relationship between magnocellular temporal resolution and higher-level aspects of visual temporal processing including inspection time, single and dual-target (attentional blink) RSVP performance, go/no-go reaction time, and rapid naming was also assessed. The Dyslexia group exhibited significant deficits in magnocellular temporal resolution compared with controls, but the two groups did not differ in parvocellular temporal resolution. Despite the significant group differences, associations between magnocellular temporal resolution and reading ability were relatively weak, and links between low-level temporal resolution and reading ability did not appear specific to the magnocellular system. Factor analyses revealed that a collective Perceptual Speed factor, involving both low-level and higher-level visual temporal processing measures, accounted for unique variance in reading ability independently of phonological processing, rapid naming, and general ability.

Deficits in attentional control: Cholinergic mechanisms and circuitry-based treatment approaches.

Sarter, Martin; Paolone, Giovanna

Behavioral Neuroscience, Vol 125(6), Dec 2011, 825-835. doi: 10.1037/a0026227

Abstract

1. The cognitive control of attention involves maintaining task rules in working memory (or "online"), monitoring reward and error rates, filtering distractors, and suppressing prepotent, and competitive responses. Weak attentional control increases distractibility and causes attentional lapses, impulsivity, and attentional fatigue. Levels of tonic cholinergic activity (changes over tens of seconds or minutes) modulate cortical circuitry as a function of the demands on cognitive control. Increased cholinergic modulation enhances the representation of cues, by augmenting cue-evoked activity in thalamic glutamatergic afferents, thereby increasing the rate of detection. Such cholinergic modulation is mediated primarily via α4β2* nicotinic acetylcholine receptors. Animal experiments and clinical trials in adult patients with ADHD indicate that attentional symptoms and disorders may benefit from drugs that stimulate this receptor. Tonic cholinergic modulation of cue-evoked glutamatergic transients in prefrontal regions is an essential of the brain's executive circuitry. This circuitry model guides the development of treatments of deficits in attentional control. (PsycINFO Database Record (c) 2011 APA, all rights reserved)component of the brain's executive circuitry.

Let the data speak. McGrew (2009) CHC intelligence article #6 most cited in journal Intelligence

I was just doing some fun web browsing at the journal web site for the most prestigious journal in the field of intelligence (Intelligence) and was pleasantly surprised to see that my 2009 invited editorial is currently among the most cited articles in the journal (#6), and was #12 in the most read articles. Damn....this makes my day. Thanks to all who have read and cited it. This will make my mom and dad proud.

CHC theory and the human cognitive abilities project: Standing on the shoulders of the giants of psychometric intelligence research. Intelligence, Volume 37, Issue 1, January 2009, Pages 1-10, McGrew, K.S.

Abstract

During the past decade the Cattell-Horn Gf-Gc and Carroll Three-Stratum models have emerged as the consensus psychometric-based models for understanding the structure of human intelligence. Although the two models differ in a number of ways, the strong correspondence between the two models has resulted in the increased use of a broad umbrella term for a synthesis of the two models (Cattell-Horn-Carroll theory of cognitive abilities-CHC theory). The purpose of this editorial is three-fold. First, I will describe the CHC framework and recommend that intelligence researchers begin using the CHC taxonomy as a common nomenclature for describing research findings and a theoretical framework from which to test hypotheses regarding various aspects of human cognitive abilities. Second, I argue that the emergence of the CHC framework should not be viewed as the capstone to the psychometric era of factor analytic research. Rather, I recommend the CHC framework serve as the stepping stone to reinvigorate the investigation of the structure of human intelligence. Finally, the Woodcock-Muñoz Foundation Human Cognitive Abilities (HCA) project, which is an evolving, free, on-line electronic archive of the majority of datasets analyzed in Carroll's (1993) seminal treatise on factor analysis of human cognitive abilities, is introduced and described. Intelligence scholars are urged to access the Carroll HCA datasets to test and evaluate structural models of human intelligence with contemporary methods (confirmatory factor analysis). In addition, suggestions are offered for linking the analysis of contemporary data sets with the seminal work of Carroll. The emergence of a consensus CHC taxonomy and access to the original datasets analyzed by Carroll provides an unprecedented opportunity to extend and refine our understanding of human intelligence. © 2008 Elsevier B.V.

Detterman's Bytes: On IQ test standardization

So true. Another Detterman's tidbit of expertise.

"As the saying goes, any fool can make a test and many do. The really important part of making a good test is the work done after the test has been devised. This is most often, but not always, done by commercial test producers. Producing an accurate, usable test can cost millions of dollars. Though it may be academics that develop the concept for tests, it is those who do the hard and often tedious work of standardizing the test that make it useful."

Salthouse on aging/intelligence paradox

"An intriguing discrepancy exists between the competencies of older adults, assumed on the basis of everyday observations, on the one hand, and their competencies inferred from laboratory results, on the other hand. The laboratory results tend to portray older adults as distinctly inferior to young adults on a number of presumably basic cognitive abilities, and yet we are all aware of competent, and even remarkable, accomplishments of people well into their 60s, 70s, and beyond. One is thus faced with the question of how to account for this apparent discrepancy between the rather pessimistic results of the laboratory and the more encouraging observations of daily life. (Salthouse 1987, p. 142)"

PsycNET - Display Record: Working memory has both domain-general and specific constraints

What limits working memory capacity? Evidence for modality-specific sources to the simultaneous stor

There is considerable debate on whether working memory (WM) storage is mediated by distinct subsystems for auditory and visual stimuli (Baddeley, 1986) or whether it is constrained by a single, central capacity-limited system (Cowan, 2006). Recent studies have addressed this issue by measuring the dual-task cost during the concurrent storage of auditory and visual arrays (e.g., Cocchini, Logie, Della Sala, MacPherson, & Baddeley, 2002; Fougnie & Marois, 2006; Saults & Cowan, 2007). However, studies have yielded widely different dual-task costs, which have been taken to support both modality-specific and central capacity-limit accounts of WM storage. Here, we demonstrate that the controversies regarding such costs mostly stem from how these costs are measured. Measures that compare combined dual-task capacity with the higher single-task capacity support a single, central WM store when there is a large disparity between the single-task capacities (Experiment 1) but not when the single-task capacities are well equated (Experiment 2). In contrast, measures of the dual-task cost that normalize for differences in single-task capacity reveal evidence for modality-specific stores, regardless of single-task performance. Moreover, these normalized measures indicate that dual-task cost is much smaller if the tasks do not involve maintaining bound feature representations in WM (Experiment 3). Taken together, these experiments not only resolve a discrepancy in the field and clarify how to assess the dual-task cost but also indicate that WM capacity can be constrained both by modality-specific and modality-independent sources of information processing.

Can the focus of attention accommodate multiple, separate items?

Researchers of working memory currently debate capacity limits of the focus of attention, the proposed mental faculty in which items are most easily accessed. Cowan (1999) suggested that its capacity is about 4 chunks, whereas others have suggested that its capacity is only 1 chunk. Recently, Oberauer and Bialkova (2009) found evidence that 2 items could reside in the focus of attention, but only because they were combined into a single chunk. We modified their experimental procedure, which depends on a pattern of switch costs, to obtain a situation in which chunking was not likely to occur (i.e., each item remained a separate chunk) and still obtained results consistent with a capacity of at least 2 items. Therefore, either the focus of attention can hold multiple chunks or the switch cost logic must be reconsidered. (PsycINFO Database Record (c) 2011 APA, all rights reserved)

Working memory, attention, and mathematical problem solving: A longitudinal study of elementary scho

The role of working memory (WM) in children's growth in mathematical problem solving was examined in a longitudinal study of children (N = 127). A battery of tests was administered that assessed problem solving, achievement, WM, and cognitive processing (inhibition, speed, phonological coding) in Grade 1 children, with follow-up testing in Grades 2 and 3. The results were that (a) Grade 1 predictors that contributed unique variance to Grade 3 word problem-solving performance were WM, naming speed, and inhibition and (b) growth in the executive component of WM was significantly related to growth in word problem-solving accuracy. The results support the notion that growth in the executive system of WM is an important predictor of growth in children's problem solving beyond the contribution of cognitive measures of inattention, inhibition, and processing speed as well as achievement measures related to calculation and reading.

Thinking..fast and slow: Dual process models of cognition/intelligence--hot topic

Dual cognitive process (sometimes called Type I/II processing) have increased in prominence the past five years.  Within the past few weeks the long anticipated book "Thinking, Fast and Slow" by Daniel Kaneham was released, and it is already near the top of most non-fiction best selling books.  I can't wait to get my copy, as it will put Malcom Gladwell's "Blink" in it's proper place.  This will give the layperson, and many professionals, a better understanding of these two general classes of cognitive processes.

My thinking about applied intelligence test development and interpretation has been incorporated this general dichotomy in the form of a working (evolving) test development/interpretation framework (see summary figure below).

Gabby Giffords response to music therapy: Fine-tunning the brain clock via rhythm

Very interesting story and video regarding speech and language therapy progress for Congresswoman Gabby Giffords.

The use of music therapy is consistent with rhythm-based intervention programs.  One of this class of interventions mentioned in the article is melodic intonation therapy (MIT).  MIT is one of a class of rhythm-based therapies that have demostrated significant progress not only for brain-injury related aphasia, but other clinical disorders.  The Brain Clock blog has made many posts regarding the importance of brain rhythm or timing, with the master internal brain clock possibly being the underlying cognitive/brain mechanism that may be being "fine tuned" by these therapies.

A recent white paper that reviewed the efficacy of 23 different rhythm-based therapies can be found here. I recently blogged about one of these neurotechnologies, namely Interactive Metronome, at the IM-Home web page blog.  My post can be found here.  In a post to be released any day, I touch on the above white paper that concluded:

"After a review of four different types of rhythm-based timing treatments, of which IM was just one, we concluded that:

“we believe that collectively the preponderance of positive outcomes (across the 23 listed studies) indicates that rhythm-based mental-timing treatments have merit for clinical use and warrant increased clinical use and research attention…positive treatment outcomes were reported for all four forms of rhythm-based treatment.  Positive outcomes were also observed for normal subjects and, more importantly, across a variety of clinical disorders (e.g., aphasia, apraxia, coordination/movement disorders, TBI, CP, Parkinson's disease, stroke/CVA, Down's syndrome, ADHD)….One notable observation of interest is that 15 of the 23 studies (the RAS, AOS-RRT and SMT treatment studies) all employed some form of auditory-based metronome to pace or cue the subjects targeted rhtymic behavior.  In all other studies, rhythm-pacing used some form of manual tapping or beat sound (e.g., drum).  We conclude that the use of external metronome-based rhythm tools (tapping to a beat, metronome-based rhythmic pacing, rhythmic-cuing via timed pulses/beats) is a central tool to improving temporal processing and mental-timing.”

Blogging status: BlogPress on the fritz and IAP's blogs going pro

Regular readers may have noticed a significant decrease in blog posts the past few weeks.  Why? 

I had moved all my blogging to my iPad as I have found it a much more efficient method for posting.  However, a few weeks ago Apple released its new IOS5.0 operating system.  After updating my iPad, my BlogPress app would crash.  I visited the developers web page and they had a note indicating they were aware of the crash and had submitted a fix to Apple for review.  I have been checking daily for the app upate, but it is not showing up.  So, please be patient.  I may go "old school" and do some blogging from my PC.

Also, I am just starting work with a professional web development company to integrate my IAP web page and professional blogs into a single professional looking (andmore efficient) web portal..  I will be spending significant time working with the developer on this new internet portal and migration of materials to the new server.  I have no idea how long this will take.

In the end the work will be worth it......so be patient.  I will do what I can to get back "up" and blogging with more regularity.  As soon as BlogPress gets the new app, you should see an uptick in posts. 

Thanks for your patience

IQ's Corner: Coming out of the neurotech closet

[Note.  This post was originally written to be distributed to a number of professional listservs.  I then decided against that idea, and instead, produce it here as a blog post.  I will be sending brief FYI (with links to this post) to a number of professional listservs.  So, it sounds like a listserv post...which it originally was...but it is now a blog post.]

Anyone who has followed my blogs knows that during the past 5 years, aside from my IQ's Corner blog, I have nurtured a sister blog addressing mental timing research (the Brain Clock blog..previously nicknamed the IQ Brain Clock). 

My interest in the brain clock, and other brain training/fitness technology, piqued as a result of my involvement (very skeptical at first) in a study directed by Gordon Taub in 2004.  Taub, myself, and one of the best stat/methodologists in school psychology (Dr. Tim Keith) published an article in Psychology in the Schools (Taub, McGrew & Keith, 2007) that reported that Interactive Metronome (IM) training resulted in significant increases in the fluency of basic reading skills when compared to control group subjects (randomly assigned treatment and control groups).  The results floored me...as I had become a huge skeptic of non-academic interventions for academics...as I had many scars from the early LD "process remediation" treatment days of Frostig, ITPA psycholinguistic training, Doman-Delacato motor pattern retraining, etc.).  I thus set out on a 5 year mission to explore the brain clock/mental timing research literature, which I have posted portions of at the Brain Clock blog.  I needed to now why such an elegant neurotechnology could have positive impacts on such diverse domains as ADHD, golf, tennis, reading, and stroke rehab.  It had to be working on some kind of cognitive domain-general mechanism.

I have become convinced that this apparently simple (it is not so simple if you give it a try...it places huge demands on attentional control and executive functions) neurotechnology may be (my working hypotheses) fine tuning the resolution of the underlying human brain clock (or system of clocks), and might be increasing the resolution of neural oscillations as per Jensen's neural efficiency hypothesis.  The brain clock literature has huge overlaps with the contemporary g and executive functions literature, and especially exciting research by Rammsayer et al regarding "temporal g" (which appears more highly correlated with psychometric g than Jensen's reaction time g).  These parallel sets of research all focus on similar neuro constructs and brain networks (the central executive network and the salience/attentional networks...as per recent research on large scale brain networks....the other being the default mode network; see Bressler and Menon, 2010; Large-scale brain networks in cognition: Emerging methods and principles, Trends in Cognitive Science, Vol 14, Issue 6, pp 277-290).

I won't go into greater detail.  I am going to provide the detail via a series of blog posts at the IM Home web site ---  via the blog feature.  My blog posts will be written for the lay audience, and will contain links back to my Brain Clock blog for the harder science.  My first post is now up and availale (click here)
