A reliability coefficient of .80 (Baddeley, 1968) and a correlation coefficient of .59 (p < .001) was reported with the British Army Verbal Intelligence
Test (Baddeley, 1968).
It was found that verbal fluency tests correlated about 0.30 with Verbal Intelligence
Quotient (IQ) and Full Scale IQ.
Mothers were administered the Peabody Picture Vocabulary Test (PPVT) (Dunn 1997) to assess maternal verbal intelligence
twice, at child age 6 mo and again at 9 y old; the Center for Epidemiologic Studies Depression Scale (CES-D) (Radloff 1977) to assess maternal depression when the child was 1, 3, 7, and 9 y old; and the Home Observation for the Measurement of the Environment-Short Form (HOME-SF) (Caldwell and Bradley 1984) to assess the home learning environment when the child was 3, 7, 9, and 10 1/2 years of age.
Retest reliability was reported to be 0.80, and evidence of validity was provided by reporting a correlation coefficient of 0.59 with the British Army verbal intelligence
test (Baddeley, 1968).
In essence, NI is looked upon as a mode of communication, which specifically deals with inter- and intra-personal competencies tied with Verbal Intelligence
(VI) (Randall, 1999).
This develops their verbal intelligence
or vocabulary and non-verbal intelligence and reasoning power as well.
The scientists at Lakehead University, Ontario, found those who admitted being worriers scored more highly on verbal intelligence
tests and said worrying could have helped our ancestors survive.
YOU'LL WRITE A BEST-SELLER IN THE Canadian study mentioned above, those who worried more scored higher for verbal intelligence
, and verbally intelligent people are better at reading and writing.
The study analyzed parenting behaviors and whether they had an effect on verbal intelligence
as measured by the Picture Vocabulary Test (PVT).
Reading was associated not only with measures of verbal intelligence
(such as vocabulary tests) but with measures of nonverbal intelligence as well (such as reasoning tests).
The results indicate that the verbal intelligence
, kinesthetic intelligence, musical intelligence interpersonal intelligence, intrapersonal intelligence, and naturalist intelligence scores of the girls who took part in the study were all higher, at a statistically significant level, than those of the boys.
scores at age seven increased by 0.35 points for every extra month of breastfeeding.
