Abstract
Neuroimaging studies, using various modalities, have evidenced a link between the general intelligence factor (g) and regional brain function and structure in several multimodal association areas. While in the last few years, developments in computational neuroanatomy have made possible the in vivo quantification of cortical thickness, the relationship between cortical thickness and psychometric intelligence has been little studied. Recently, cortical thickness estimations have been improved by the use of an iterative hemisphere-specific template registration algorithm which provides a better between-subject alignment of brain surfaces. Using this improvement, we aimed to further characterize brain regions where cortical thickness was associated with cognitive ability differences and to test the hypothesis that these regions are mostly located in multimodal association areas. We report associations between a general cognitive ability factor (as an estimate of g) derived from the four subtests of the Wechsler Abbreviated Scale of Intelligence and cortical thickness adjusted for age, gender, and scanner in a large sample of healthy children and adolescents (ages 6–18, n = 216) representative of the US population. Significant positive associations were evidenced between the cognitive ability factor and cortical thickness in most multimodal association areas. Results are consistent with a distributed model of intelligence."
Multimodal n-back with cross-modal association should be tested for greater improvement in the cognitive ability factor than may occur with other forms of n-back, as training may positively affect multimodal association areas. This may potentially relate to associative learning, which has been found to be a more effective mechanism in determining g than does processing speed or working memory. Nevertheless, the potential remains for more effective utilization of working memory by these integrated areas making substantial contributions to the factor of general intelligence.

I doubt modality has anything to do with it. The central feature is probably something along the lines of increased intracortical awareness. Since it is known that the ACC becomes more active during WM training, I don't think this is a leap into the unknown. At some point it will be a matter of this subsystem's capacity to monitor multiple parallel processes that defines who's really got the bigger g.
In other words, those with higher g will outperform those with lower g on the basis of parallel tasks.
Those with greater self-awareness will reign supreme. *pats self on back*

Unconscious activation of the prefrontal no-go network.

Abstract
Cognitive control processes involving prefrontal cortex allow humans to overrule and inhibit habitual responses to optimize performance in new and challenging situations, and traditional views hold that cognitive control is tightly linked with consciousness. We used functional magnetic resonance imaging to investigate to what extent unconscious "no-go" stimuli are capable of reaching cortical areas involved in inhibitory control, particularly the inferior frontal cortex (IFC) and the pre-supplementary motor area (pre-SMA). Participants performed a go/no-go task that included conscious (weakly masked) no-go trials, unconscious (strongly masked) no-go trials, as well as go trials. Replicating typical neuroimaging findings, response inhibition on conscious no-go stimuli was associated with a (mostly right-lateralized) frontoparietal "inhibition network." Here, we demonstrate, however, that an unconscious no-go stimulus also can activate prefrontal control networks, most prominently the IFC and the pre-SMA. Moreover, if it does so, it brings about a substantial slowdown in the speed of responding, as if participants attempted to inhibit their response but just failed to withhold it completely. Interestingly, overall activation in this "unconscious inhibition network" correlated positively with the amount of slowdown triggered by unconscious no-go stimuli. In addition, neural differences between conscious and unconscious control are revealed. These results expand our understanding of the limits and depths of unconscious information processing in the human brain and demonstrate that prefrontal cognitive control functions are not exclusively influenced by conscious information.
Just thought I'd post this. Kinda cool.

I find my triple n-back scores are comparable with single n-back, at my maximum TNB level. What if potential for remembering multiple sequences is separate from working memory capacity? I think I form combined memories of the information per trial. In this sense I do not think it is intracortical, it is the relevant part of the cortex, perhaps the association cortex, which orchestrates the compression of information stored in the hippocampus. While the average Japanese digit span is higher than that of an English speaker due to the complexity of numbers, skilled digit spans are similar, with the most basic association. ...It is perhaps related to cortical power... Maybe this type of definition could be uniform...I'm not sure about genetics. How does this relate to your understanding of how modalities interact, from a cortical perspective, medstu.wt

"What if potential for remembering multiple sequences is separate from working memory capacity?"
Nope. Not possible.
"Intracortical" refers to the cortex's self-interaction on a global level. Parallel processing requires high-level integration in order to maintain concentration on differentiable elements--to be stored/discarded/updated/ignored/signalled.
Digit spans are generally different for those speaking different languages due to the digits being stored in the phonological loop; were one able to store them differently, that is, through the visual-spatial sketch pad, or both, then digit spans would reflect this malleability in cognitive disposition. (Length of syllables negatively correlates with digit span.)
Modalities typically share high interaction, especially among infants; pruning leads to normalized, segregated, compartmentalized modality processing, which is then reversed through task-specific learning (reading, writing, etc.). Special cases in which pruning does not occur would correspond to synaesthetes near you. However, there are hierarchical orderings to these modality-specific processes in which the modalities naturally commingle (any layer of abstraction).
I strongly urge you to do research before leaping to unjustified conclusions. But then that would be me doing the thinking for you....

Not necessarily; what I mean is the differences between any kind of NB will prevent one from correlating them with each other in terms of one's maximum reached n-span for them.
For instance, just because one reaches T9B, doesn't mean one will be able to do D9B. The kinds of tracking that take place will affect performance in various ways, and to be articulate about these differences is impossible right now.

By removing a modality, scores on the remaining modalities would be at least equivalent. It is unclear what kind of compensation occurs by adding an additional modality, increasing from single to dual, etc. It may be that the working memory correlates--those involved in fluid intelligence--treat all multi-modal input in an equivalent manner. The difference may lie in how working memory is used--whether larger "pieces" are required by working memory, or smaller pieces for a greater number of steps. The difference between dual and single n-back may not be sufficiently great to make a distinction on the IQ tests used in the Jaeggi study--both may be near ideal. Even in 4-5NB, when n levels are considerably lower, the basic working memory training may be sufficient when combined with compensatory strategies (such as reiteration) to solve an exalted number of fluid intelligence items. Perhaps the improvements generated by single and dual n-back training can be differentiated by test item. Another possibility may be to create an inventory of strategies used to solve each problem. Perhaps some problems may be solved more efficiently by members of each group. Once the basic memory resources are there, they remain plastic and leave the window open to alternate strategies. The idea is that n-back is direct working memory training, of the type used in problem solving, and that the extended growth of neurites at the master n-back region is responsible for translating this effect. A primary advantage of increased n-back modality may be in solving problems involving more complex informational correlates--the efficient solving of problems involving the computation of more sophisticated associations. Matirix reasoning tends to rely only on the most basic relationships between informational components. Increasing the types or (co-)incidence of relationships that are a part of manipulation towards a problems solution may yield multi-modal n-back partially more effective insofar as it resembles more closely the (internal) appreciation of the steps involved in and their proximity; such problems may be more difficult than could be realized by a particular individual. I hypothesize that the most complex n-back tasks will benefit only capable individuals-perhaps only on the hardest problems more so than single n-back; there may be some utility involved in utilizing a multimodal-reland strategy in "regular" problem solving. I think the strategy used by working memory is second to the realization of problem mechanics by a superior or primary mechanism. So, people training dual n-back may employ more sophisticated and efficient mnemonic strategies which closely resemble the increase task complexity, only after encoding at the level of potential mechanics and realizing the problem-solving strategy. The new brain material may be more sophisticated than the recognition-analogous circuitry in place in the brain. This is a greater cortical function (recognition) whose potential generally exceeds that of the working memory circuit. Only some people are capable of "complex" associations--multimodal n-back would support using this type of association. Again, the best training methods are related possibly to overall g and the type of g that can be employed-during a particular problem. Over-training may be analogous to juggling, where the increased grey matter disappears when training is discontinued, and it becomes largely superfluous.

your wind is a tit long.
remember, consciousness is multimodal sensory integration, and since g is (modestly) correlated with sensory discrimination ability, i'd expect that improving multimodal binding would improve aspects of g.
its entirely possible, though, that improved updating with a larger maintained set size would improve causal calculations, enabling more efficient learning.
let's also not forget about myelination - the unexplored (unexploited?) form of enduring 'synaptic plasticity'.
even if the factory becomes great at assembling things, it needs the highway to bring it the raw materials -- and the highway will only get another lane when the demand for the product increases.

"The modest correlations found between g and measures of pitch discrimination (r = .21) and color discrimination (r = .31) suggest that sensory discrimination is relatively distinct from general intelligence." (http://www.personalityresearch.org/acton/sense.html)
Unfortunately, "multimodal" sensory integration is rather obscure from sensory discrimination. Your vague expectation seems reasonable.
Integrating modalities for joint updating is perhaps not a common occurrence, but it may enable greater brain "self-interaction," which would be a utility in creative productivity and in learning, but not necessarily in formal problem-solving disciplines, or matters of crystallized intelligence.
Considering that multimodal updating may result in improved thought characteristics, the pathways created would sustain.
Sorry there was a minor error here.
I must disagree that the Anterior Cingulate Cortex's activation thus implies increased interactivity with other regions; or that it effectively represents the primary interactions of general intelligence.

Sure, a frontal lobotomy doesn't affect IQ test scores, but it affects everything else.
ACC (in the PFC) monitors, in theory, everything in the head by contrasting it with known information (its corrective feature in error detection). The ACC is the seat of self-awareness, and self-awareness increases during WM training (ACC is activated). So, disagree all you want, but your verbosity isn't getting you on the right rack.

Anterior cingulate cortex and conflict detection: an update of theory and data.
Carter CS, van Veen V.
Imaging Research Center, University of California at Davis, Sacramento, California 95817, USA. cameron.carter@ucdmc.ucdavis.edu
Abstract
The dorsal anterior cingulate cortex (ACC) and associated regions of the medial frontal wall have often been hypothesized to play an important role in cognitive control. We have proposed that the ACC's specific role in cognitive control is to detect conflict between simultaneously active, competing representations and to engage the dorsolateral prefrontal cortex (DLPFC) to resolve such conflict. Here we review some of the evidence supporting this theory, from event-related potential (ERP) and fMRI studies. We focus on data obtained from interference tasks, such as the Stroop task, and review the evidence that trial-to-trial changes in control engagement can be understood as driven by conflict detection; the data suggest that levels of activation of the ACC and the DLPFC in such tasks do indeed reflect conflict and control, respectively. We also discuss some discrepant results in the literature that highlight the need for future research.
verbosity is infrequently helpful, but asserting without evidence is never helpful.

Error detection is a monitor function, not comparative.
Extended modalities are processed by WM without conflict.
No excessive ACC activation would seem to occur during tasks requiring multimodal integration. (Integration occurs passively, without additional error detection-unrelated to load.)
The ACC is in the Cingulate cortex, near the body of the Corpus callosum--not in the PFC.

"The cingulate cortex is usually considered part of the limbic lobe, separate from the adjacent frontal and parietal lobes." (Wikipedia)
No conflict means that no rules apply that could result in some error being detected during multimodal integration. The simultaneity of inputs does not imply greater awareness of error, beyond the increase in WM load. The ACC is just not particularly implicated in multimodal n-back.

I should add that the IQ tests scores showing this are speed-based tests (efficiency) and not power-based tests (efficacy). I have yet to see reports on anyone without their frontal lobes doing well on the Titan Test (or any other high-range test), but if such scores are affected (and I think they would be), then it is clear to me that those who are already highly intelligent will still benefit (just not in the same way as everyone--the normals--else) from WM training.
The question is finding the right kind of test that will show this...

The tri52 seems to be one of the best if not the best test of fluid intelligence on the net. I actually took the test about 3 times before training. First attempt I scored 144-145 sd15, on second and third attempts I was only able to get my score up to about 870 - 147-148 sd15 so it seems to be very reliable. After a few more months of training I'll take it again and see if anything has changed.

...There is a superior or primary mechanism, involved in the translation of problem complexity into potential mechanics and problem solving, for which n-back wm training is comparable to an extension in resources. The management of these resources is probably equivalent to the difference in type of n-back training. For this reason I think n-back training may be ideal for a particular brain and set of problems, and that superior problem-mechanical appreciation may be greatly enhanced, depending on the fundamental information components used ('typically') in "strategic" problem solving.
Increased n-back task complexity may enhance the problem solving-reciprocal nature of wm strategy and efficiency; its relationship to intelligence is relative-secondary.

This relates to the actual dimensions of g. What are the evolutionary effects of this calculation of intelligence? How is philosophy metaphysically important?
What about optimizers in g? How do they relate to the special utility of g? What is the 'ultimate' relativity of this system??
How hard is it to design a measure of evolutionary potential yielded as the functional-physical description, of info-cognitive personality...
...How may we find that people must design their own measure of personality? g has all the credit.wt,language
-reminds me that mathematicians tend to generalize...general intelligence looks optimistic (prediction).

Increased ACC activation in monkeys reduces capacity to learn visual information.
Increased intracortical coherence it may be, related to attentional-hippocampal.
Attentional manifestation may have a parent utility. These would partially relate with the limits of training. This I predict is ultimately related to this integrated cortico-subsystem.
The importance is that what this central feature is along the lines of, is not a direct indicator to measurements of g, as recall pertains externally, therein.
I have only recently started training. I have not decided what the additional attention involved in multi-modality means for my processing capability.
Training temporal order may pose a 'generative' property for intracortical awareness. Intracortical coherence would be the external physicality, in an otherwise 'functional' system.

What is the testing that would reveal multimodal n-back training?
Brain integration may be a feature of personality, effectively.
