Learning math on the streets

As in many places in the developing world, Mexican cities have many children on their streets and plazas, begging, or selling small trinkets of toys or whatever to whoever passes by. It is often difficult to turn these bright-eyed kids down, and by the end of the evening I can find my pockets full of little things that I have no use for — even while these street children are usually the obvious sales force for a supervising adult (usually mom). Interacting with these bright little salespeople reminds me of a study conducted on the streets in Recife, a large city of more than a million people on the northeast coast of Brazil. Brazil has a large population of abandoned children who live largely on the streets, and who survive in large part as street merchants. A mathematics research team decided to test the accuracy of the understanding of basic math by these street kids, by giving them a set of problems phrased in terms of the bartering and trading and counting and ‘business-planning’ that were an important part of successful operations in their rough-and-tumble environment. Needless to say, these kids were pretty savvy, and hard to fool, and got most of the answers right! The scientists THEN sat the same kids down in a classroom and gave them exactly the same problems, but in this case presented in the formal ways that math problems are presented in a paper-and-pencil school exam. The same kids got most of the answers wrong. Are these kids “smart&rdquo...

Knowledge of oscillatory entrainment and its fundamental role in cognitive and behavioral processing has increasingly been applied to research in the field of reading and developmental dyslexia. Growing evidence indicates that oscillatory entrainment to theta frequency spoken language in the auditory domain, along with cross-frequency theta-gamma coupling, support phonological processing (i.e., cognitive encoding of linguistic knowledge gathered from speech) which is required for reading. This theory is called the temporal sampling framework (TSF) and can extend to developmental dyslexia, such that inadequate temporal samp...

(University of Helsinki) A new study brings neural-level evidence that the continuous variation in natural speech makes the discrimination of phonemes challenging for adults suffering from developmental reading-deficit dyslexia.

Abstract Recent studies showed that some adults with dyslexia have difficulty processing sequentially arranged information. In a companion study, this deficit manifested as low accuracy during a word pair comparison task involving same/different decisions when two words differed in their letter sequences. This sequential deficit was associated with left/right spatial letter confusion. In the present study, we found the same underlying difficulty with sequential and spatial letter processing during word spelling. Participants were the same 22 adults with dyslexia and 20 age- and gender-matched controls as in the co...

This study explored factors predicting the number of exposures required for item reading mastery (N = 145 words). Specifically, we explored how the number of word exposures required to reach mastery varied as a function of linguistic features of the words and cognitive characteristics of the students. Using item-level crossed-random effects models, we found students required an average of 5.65 exposures for mastery, with word features representing word length, vocabulary grade, and imageability being significant predictors of learning efficiency. We also found a significant interaction between pretest word reading skill an...

obori Dyslexia, or reading disability, is found to have a genetic basis, and several related genes have been reported. We investigated whether natural selection has acted on single nucleotide polymorphisms (SNPs) that were reported to be associated with risk/non-risk for the reading disability of Chinese characters. We applied recently developed 2D SFS-based statistics to SNP data of East Asian populations to examine whether there is any sign of selective sweep. While neutrality was not rejected for most SNPs, significant signs of selection were detected for two linkage disequilibrium (LD) regions containing the report...
