When it comes to our under­stand­ing of human intel­li­gence, for too long, there has been a mis­match between the­ory and prac­tice. The­o­ret­i­cally, the two main threads run­ning through def­i­n­i­tions of intel­li­gence have been (a) adap­ta­tion to the envi­ron­ment, and (b) the cog­ni­tive, affec­tive, and voli­tional char­ac­ter­is­tics that enable that adap­ta­tion. Prac­ti­cally, IQ tests mea­sure an impor­tant but lim­ited slice of intel­lec­tual func­tion­ing in a very lim­ited test­ing envi­ron­ment. Why such a disconnect?

Intel­li­gence tests were born out of neces­sity. Read the rest of this entry »

Intel­li­gence tests offer insight into age­ing brain (BBC News):

“Sixty-six years ago today, more than 70,000 10 and 11-year-old chil­dren across Scot­land took an intel­li­gence test…now they have formed the foun­da­tion of a remark­able research project which is pro­duc­ing valu­able insights into what lies behind cog­ni­tive decline — or age­ing of the brain… Read the rest of this entry »

Team­work Builds Big Brains (Sci­ence Now):
– “The aver­age adult human’s brain weighs about 1.3 kilo­grams, has 100 bil­lion or so neu­rons, and sucks up 20% of the oxy­gen we breathe. It’s much big­ger than an ani­mal our size needs. Accord­ing to a new com­puter model, the brains of humans and related pri­mates are so large because we evolved to be social crea­tures.“
– “The idea behind the so-called social intel­li­gence hypoth­e­sis is that we need Read the rest of this entry »

NIH-funded study finds dyslexia not tied to IQ (NIH press release):

At left, brain areas active in typ­i­cally devel­op­ing read­ers engaged in a rhyming task. Shown at right is the brain area acti­vated in poor read­ers involved in the same task.

- “Regard­less of high or low over­all scores on an IQ test, chil­dren with dyslexia show sim­i­lar pat­terns of brain activ­ity, accord­ing to researchers sup­ported by the National Insti­tutes of Health. The results call into ques­tion the dis­crep­ancy model — the prac­tice of clas­si­fy­ing a child as dyslexic on the basis of a lag between read­ing abil­ity and over­all IQ scores.”

- “In many school sys­tems, the dis­crep­ancy model is the cri­te­rion for Read the rest of this entry »

Very inter­est­ing new study pub­lished in Psy­cho­log­i­cal Sci­ence: Short-Term Music Train­ing Enhances Ver­bal Intel­li­gence and Exec­u­tive Func­tion.

Abstract: Researchers have designed train­ing meth­ods that can be used to improve men­tal health and to test the effi­cacy of edu­ca­tion pro­grams. How­ever, few stud­ies have demon­strated broad trans­fer from such train­ing to per­for­mance on untrained cog­ni­tive activ­i­ties. Here we report the effects of two inter­ac­tive com­put­er­ized train­ing pro­grams devel­oped for preschool chil­dren: one for music and one for visual art. After only 20 days of train­ing, Read the rest of this entry »
