1. (2013) The effects of working memory training on functional brain network efficiency
Excerpt from abstract:
"Taken together, this is the first longitudinal study that provides evidence for the plasticity of the functional brain network underlying WM."
2.13 December 2012 - Working Memory Training Is Associated with Lower Prefrontal Cortex Activation
in a Divergent Thinking Task
Excerpt from abstract:
"Furthermore, gain in fluid intelligence mediated the effect of training on brain activation in ventrolateral prefrontal cortex. These results indicate that a short regimen of WM training is associated with lower prefrontal
activation—a marker of neural efficiency—in divergent thinking."
3. May, 2013 - Computerized working memory training: Can it lead to gains in cognitive skills in students?
Excerpt from abstract:
"There were some maintenance effects when students were tested 8 months later. Possible reasons for why the computerized working memory training led to some far transfer effects in the high-frequency Training group are included in the discussion."
4. 2013 - Exploration of an adaptive training regimen that can target the secondary memory component of working memory capacity.
Excerpt from abstract:
"The main findings suggested that the SM component of WM capacity could be targeted by lowering the recall accuracy threshold. The present findings are important because they suggest that adaptive training regimens can be designed that selectively target specific components of WM capacity, and they raise the possibility that the potency of existing training regimens can be increased."
5. Conventional working memory training may not improve intelligence
Commentary (where the abstract "would" be):
"A recent study by Redick and colleagues found no improvements in cognition or intelligence after working memory training using a randomized, placebo-controlled design. Here, I argue that, although conventional training protocols may be ineffective, positive effects might be obtained when future research takes into account factors known to promote more general learning."
6. 2012 - Improving attention control in dysphoria through cognitive training: Transfer effects on working memory capacity and filtering efficiency
Excerpt from abstract:
"Dysphoric participants in the training group showed training-related gains in working memory that were accompanied by gains in working memory capacity and filtering efficiency compared to an active control group. Results provide important initial evidence that behavioral performance and neural function in dysphoria can be improved by facilitating greater attentional control."
7. Title - Brain Training Game Boosts Executive Functions, Working Memory and Processing Speed in Young Adults: A Randomized Controlled trial
Excerpt from the abstract:
"The title says it all."

Please feel free to add any others down below, just try to keep them as recent as possible though, also, it would be polite if you ran the title through the groups search engine to see if its been discussed in the past before. Apologies if I've made a mistake here myself.

I don't have access to the articles, but are the result positive? Does Dual N back work???? How does take it take for significant improvement to show up according to them?/??

I believe we've already discussed the Slagter and Vartanian ones, actually.

(Looking at the others, the Alloway one seems to be new; and the
Nouchi _Brain Age_ study shows no gain to fluid intelligence, no
surprise.)

Yeah, they don't claim anything about fluid intelligence, only the findings _related_ to WM. Which makes sense, no this drug can't help you lose weight (you have to read the fine-print to find out though) but at least it will improve your muscle tone (marketing trick - people might relate improved muscle tone with weight reduction - but I digress, in a very cloudy way), sort of thing.
See results: "Results showed that the Brain Age group improved all measures of the executive functions, all measures of the working memory , and all measures of the processing speed compared to the Tetris group. "
See results: "playing Brain Age or Tetris did not improve one the measure of fluid intelligence , one of two measures of attention, any measure of short-term memory , or the measure of reading ability.
** I'm surprised about the null result relating to short-term memory and reading comprehension given that there were improvements found in WM. Not surprised about the fluid intelligence result if STM didn't improve though. Confusion might be lifted if I decide to read more about the tasks and find out more about their bulls eye range.
Those who fancy Tetris - apparently it may improve your visual-spatial prowess, at least, that is until you become Dr. Block man (awesome at it - what was your thesis on, 4D tetris?).
See Results:
"On the other hand, the Tetris group improved one of two measures of attention and the measure of visuo-spatial ability compared to the Brain Age group. These results show that the effects of playing Tetris were transferred to attention and visuo-spatial ability."
** No though, I wont be planting either plant in my garden of fun. I've heard of better seeds to help one's appetite here blossom.
(Unless there was something else?) Moving on...

Tracy Packham Alloway's "Computerized Working Memory Training" was mentioned in https://groups.google.com/forum/?fromgroups#!searchin/brain-training/Computerized$20working$20memory$20training/brain-training/Fg43INj05jU/KUL0-OfBn8AJ.
She and her husband basically founded the Jungle Memory game, which she uses in her many positive studies, but does not seem to disclose the huge conflict of interest.

(2013) Dopamine and training-related working-memory improvement
Abstract:
Converging evidence indicates that the neurotransmitter dopamine (DA) is implicated in working-memory (WM) functioning and that WM is trainable. We review recent work suggesting that DA is critically involved in the ability to benefit from WM interventions. Functional MRI studies reveal increased striatal BOLD activity following certain forms of WM interventions, such as updating training. Increased striatal BOLD activity has also been linked to transfer of learning to non-trained WM tasks, suggesting a neural signature of transfer. The striatal BOLD signal is partly determined by DA activity. Consistent with this assertion, PET research demonstrates increased striatal DA release during updating of information in WM after training. Genetic studies indicate larger increases in WM performance post training for those who carry advantageous alleles of DA-relevant genes. These patterns of results corroborate the role of DA in WM improvement. Future research avenues include: (a) neuromodulatory correlates of transfer; (b) the potential of WM training to enhance DA release in older adults; (c) comparisons among different WM processes (i.e., updating, switching, inhibition) regarding regional patterns of training-related DA release; and (d) gene–gene interactions in relation to training-related WM gains

P.S - I'd like to continue adding things to this topic overtime, if anyone has any qualms with this just let me know. Preferably, particular articles won't be discussed here, only listed, where, like what I've done above, discussion on a particular paper will be encouraged really only as an independent topic, rather than clouding all the *before and after* entries here.
Thanks,
Mike

(2013) Intelligence and working memory control: Evidence from the WISC-IV administration to Italian children
excerpt from abstract ----> ** To explain these differences, it has been argued that WM is an articulated system and only its more attentional components are strictly related with GI. In particular, it has been argued that WM tasks can be located – according to the task characteristics and the subject's age – along a continuum, from the most passive tasks, which do not require cognitive control, to the most active tasks, which do require high cognitive control.**

(2013) Training your brain: Do mental and physical (MAP) training enhance cognition through the process of neurogenesis in the hippocampus?
HIGHLIGHTS
► Mental or physical training increase hippocampal neurogenesis and facilitate learning. ► Neurogenesis is required for some, but not all, cognitive enhancing effects of training. ► Mental training has its greatest effect when difficult, but attainable. ► Larger effects may be observed following a combination of both mental and physical (MAP) training.

Highlights
- •
IQ scores are predicted by individual differences in sensory discriminations
- •
High IQ is associated with motion perception impairments as stimulus size increases
- •
The results link intelligence and low-level suppression of sensory information
- •
Suppressive processes are a key constraint of both intelligence and perception
