Quote:
Children of women who reported domestic violence in pregnancy or during the first six years of the child's life are almost 50% more likely to have a low IQ at age 8, research finds.

In the study by University of Manchester epidemiologists, 13% of children whose mothers did not experience domestic violence had an IQ of below 90 at 8 years of age.

If their mothers experienced physical violence from their partner either in pregnancy or during the first six years of the child's life, the figure rises to 22.8%.

The team led by Dr Kathryn Abel from The University of Manchester show the chance of a low IQ rises to 34.6% if the mother was repeatedly exposed to domestic violence.

I don't see if they screened for social factors - simultanous social factors are correlated with domestic abuse and low IQ.
Might be common cause (low social class) or even more complex relationship between social class, domestic abuse and intelligence.

Abused kids just don’t feel the motivation to do the various subtests which are more abstract than others, and require more inspiration.

Perhaps it’s a matter of “relevance.”

That's another factor, children of abused mothers are very likely to be abused themselves.

If one looks at some of the subtests of the Wechsler’s Adult Intelligence Scale, one would feel that people who lack motivation wouldn’t do well on them.

Because they might feel there’s no relevance to their real life.

You've both raised good points . Are lower IQ families ones in which domestic abuse is more likely to happen ?

Domestic abuse certainly doesn’t help matters....it might, paradoxically, motivate some folks more, though.

This sounds like it might be a case of correlation vs causation.

It’s a vicious circular pattern, really.

Both create the same results: lower IQ scores.

Imagine just getting slapped around by your father...and having to take an IQ test?

Does motivation lead to higher IQ scores or does higher IQ make you more motivated ?

Certainly - IQ tests require quite an effort, without motivation you don't get high score

Maybe.

Depends upon the individual.

But it’s probably a little bit of both in most people.

For practical purposes, both should be considered. And the preponderance of one over the other should be assessed.

There may also be the factor that low IQ people are more likley to suffer abuse, the children may be inheriting genetic conditions associated with learning disabilities from their mothers

High-IQ people abuse children pretty darn often, too.
