Babies want to speak as early as 7 months
Babies usually start speaking by their first birthday. But new research suggests talking to your baby stimulates his brain well before she utters those first words.
For the study, published Monday in the journal Proceedings of the National Academy of Sciences, the authors compared how 7- and 11-month-old babies from English-speaking families processed sounds from English and Spanish.
Researchers at the University of Washington looked at 57 babies who were 7, 11 and 12 months old. The babies sat in an egg-shaped, noninvasive brain scanner that measures brain activation and listened to speech sounds played over a loudspeaker.
The researchers examined patterns of brain activation in areas of the brain that analyze sound, as well as areas that plan the motor movements required to produce speech.
At 7 months, infants responded equally to sounds from both English and Spanish.
“Babies are citizens of the world,” Dr. Patricia Kuhl, the lead researcher on the study, said. “They’re not committed to any language or any languages. They’re just open.”
At 11 months, however, the infants saw greater activation of the motor areas in the brain for English sounds. Kuhl said this suggests that as infants’ brains develop further, they focus in on sounds familiar to them.
“What we believe is happening is that the babies are dying to talk back,” Kuhl said. “It means that babies even at an early age are practicing and rehearsing and activating brains in a social way so that when we serve something to them, they’re attempting to volley back.”
These findings reinforce the importance of talking to your baby, instead of just plopping him or her in front of the television.
“When [babies] look at the TV set, they seem interested but their brains don’t learn,” Kuhl said. “Babies recognize and can distinguish the sounds only if they heard live speakers present to them – only if they were interacting socially.”
Dr. Gordon Ramsay, director of the spoken communication laboratory at the Marcus Autism Center in Atlanta, said multiple elements are at play when infants learn how to speak.
“The message for parents is that speech acquisition in infancy is built upon a scaffold of sensory experience, motor activity and social interaction,” Ramsay said. “All these components need to come together in the natural resonant coupling between child, caregiver and environment if every child is to progress along the path to spoken language.”
However, Ramsay says the study should have followed the same babies through the course of their development, rather than examining different 7-month-olds and 11- and 12-month-olds.
“Because developmental timing is so important, and there is so much variability and delay within children, it’s really important to do longitudinal studies,” Ramsay said.

Have scientists devised the formula for lasting love
Love is aggravating, Ellusive, Intangible. It starts in that sweet spot between intimacy and excitement which doesn't seem possible to manufacture and tiring to maintain. Can the algorithms of online dating sites or indeed the long odds of stumbling upon your perfect partner down the local pub ever predict where, When or for period cupid will strike?
Whilst science has not yet processed the perfect partner, specialised mathematicians are claiming to have found the formula that predicts how long love will last. Research commissioned by MSN has revealed a new love equation that determines the key ingredients to a positive, Long lasting romance with factors such as a good sense of humour ranking in importance alongside a person's number of previous sexual partners.
in line with the 2,000 males and females surveyed, 25 per cent of women and men believe their partner should have had four sexual partners before them (With one in five men clinging to the belief that they should be their ideal woman
The survey also found that men prioritise looks over intelligence and are twice as likely as women to believe that good sex is important for a happy, Enduring spouse.
The biggest surprise for me was that the number one trait we're all apparently after is wit. So there you have it, It's not sex appeal but sparkling banter that'll make you a hit with potential partners.
It is claimed that the caused formula (l = 8 +.5Y.2P +.9Hm +.3Mf + m.3G.5(Sm Sf)2 + my husband and i + 1.5C see key further down) Can determine how long a potential or current relationship to expect to last.
Does it go a long way? I decided to test the hypothesis through extremely precise means (for instance, By broadcasting around the globe, Via twittollower, That I am single and ready to mingle in a mathematically approved fashion). I applied the formula to various unsuspecting male friends and volunteers throughout an afternoon, and finally found a man with whom love would apparently last 12.9 seasons.
Only trouble is. i wouldn't fancy him. And despite the 12.9 happy years i offer him, He doesn't particularly fancy having a go either. That's knowledge for you. Back to your chance board.
The formula pronounced:
l = 8 +.5Y.2P +.9Hm +.3Mf + n.3G.5(Sm Sf)2 + my family and i + 1.5C
d: The predicted length in years of romantic relationship
ful: The number of years the two people knew each other before romantic relationship became serious
r: could be previous partners of both people added together
Hm: The importance the male partner attaches to honesty in romantic relationship
Mf : The importance the female attaches to money in every thing has become
c: the importance both attach to humour (Added as a group)
grams: value both attach to good looks (Added jointly)
Sm and Sf = The importance male and female attach to adam4adam review sex
I = gambling attached to having good in laws (Added to one another)
C= The importance attached to children in romantic relationship (Added in unison)
be aware of: All 'importance' measures can be scaled from 1 to 5 where 1 is not important at all and 5 is.
Research findings for same sex couples differed slightly from heterosexual couples restrictive formula changes slightly in light of this to L = 8 +.5Y.2P + 2J.3G.5(S1 S2)2 anyway i + 1.5C (Where S1 and S2 are the two partner ratings for the significance of sex).
