first birthdays, babies start shifting back to look you in the eye again

University of Iowa psychology professor Bob McMurray, who also studies speech development.

quality face-time with your tot is very important for speech development – more than, say, turning on the latest baby DVD.

Other studies have shown that babies who are best at distinguishing between vowel sounds like "ah" and "ee" shortly before their first birthday wind up with better vocabularies and pre-reading skills by kindergarten.

babies also look to speakers' faces for important social cues about what they're hearing

So he and doctoral student Amy Hansen-Tift tested nearly 180 babies, groups of them at ages 4, 6, 8, 10 and 12 months. How? They showed videos of a woman speaking in English or Spanish to babies of English speakers. A gadget mounted on a soft headband tracked where each baby was focusing his or her gaze and for how long.

They found a dramatic shift in attention: When the speaker used English, the 4-month-olds gazed mostly into her eyes. The 6-month-olds spent equal amounts of time looking at the eyes and the mouth. The 8- and 10-month-olds studied mostly the mouth.

At 12 months, attention started shifting back toward the speaker's eyes.

at 6 months, babies begin observing lip movement, Lewkowicz says, because that's about the time babies' brains gain the ability to control their attention rather than automatically look toward noise.

“Once Mischel began analyzing the results, he noticed that low delayers, the children who rang the bell quickly, seemed more likely to have behavioral problems, both in school and at home. They got lower S.A.T. scores. They struggled in stressful situations, often had trouble paying attention, and found it difficult to maintain friendships. The child who could wait fifteen minutes had an S.A.T. score that was, on average, two hundred and ten points higher than that of the kid who could wait only thirty seconds.” - Jonah Lehrer from his piece in the New Yorker, “Don’t”

“The future is always ideal: The fridge is stocked, the weather clear, the train runs on schedule and meetings end on time. Today, well, stuff happens.” - Hara Estroff Marano in Psychology Today

Interestingly, these results suggest that although almost everyone has problems with procrastination, those who recognize and admit their weakness are in a better position to utilize available tools for precommitment and by doing so, help themselves overcome it. - Dan Ariely, from his book “Predictably Irrational”
