Slow vocab growth associated with hyperactivity in kids

The relevant academic journal article is Vocabulary development and trajectories of inattention-hyperactivity and emotional symptoms via academic ability and peer problems" by Elizabeth Westrupp et al.

It's a very painstaking piece of research but is greatly impoverished theoretically.  They don't seem to have realized that all they did was to rediscover IQ.  Yes, that pesky IQ again that no respectable academic may mention these days. Low IQ is of course associated with slow language development and all sorts of health and behavioral problems in later life. The prisons are full of low IQ people.  So Elizabeth and her friends have just reinvented the wheel.  Sad

Political correctness is a plague on all research concerning human beings.  So much effort has been put into research that is inconclusive due to the failure to account for IQ differences. If IQ WERE controlled for, most of the brightly-reported "findings" would lapse into statistical non-significance or negligible significance

In science, political correctness is a great evil.  It is a relentless enemy of truth


Children whose vocabulary skills develop slowly are more likely to experience emotional and behavioural issues in adolescence, according to a new Deakin University study, published today in the journal Child Development.

The research, led by Deakin School of Psychology researcher Dr Elizabeth Westrupp, was the first to model how children's language development influences changes in mental health problems over a 10 year period, from early childhood to adolescence.

"We found new evidence that lower growth in vocabulary over primary school was associated with increased child hyperactivity-inattention at eight to nine years, and more rapid increases in hyperactivity-inattention over early to middle teenage years, up to 14 to 15 years," Dr Westrupp said.

"These findings show the importance of monitoring children through middle childhood and adolescence as they develop."

As part of the study, data was gathered from almost 5000 Australian children, with children assessed six times between four and 15 years of age.

Dr Westrupp said the study also investigated possible reasons for the association between language development and behavioural issues.

"We found that children's academic experiences in middle childhood explained the link between early vocabulary development and teenage emotional and behavioural problems," she said.

"It may be that children with lower vocabulary skills struggle more in the classroom with reading and literacy, which then leads to the development of behavioural and emotional problems in teenage years."

Dr Westrupp said early literacy-based interventions may alleviate declining academic, emotional and behavioural functioning in adolescence.

"There's already some evidence to suggest that children with early language problems have higher rates of behavioural and emotional difficulties compared to other children," Dr Westrupp said.

"However prior research only looked at children at one point in time, and we know that children's language ability and mental health are not static, they change as children grow.

"Understanding these associations will allow parents and teachers to better support children in preventing childhood mental health problems."

Dr Westrupp said it was critical the focus was not just on kids who entered school with low language skills, but also kids who were dropping behind their peers in the first few years of primary school.

"We need to be aware that they are also at risk. Schools and parents must work together to identify and monitor children falling behind in language, that means having supportive and regular conversations about how a child's language is developing," she said.

"It also means oral language based interventions in the classroom may be important beyond just the first few years of primary school, and incorporating specialist oral language skills and interventions into the standard curriculum could be beneficial. So that's working with children around the meaning of words, the structure of words, and using words in new contexts.

"There is some explicit language teaching in the first years of formal schooling, but there's much less focus in older years. So a continued emphasis on these skills would help us to best support children to thrive."
