Babies can understand
each other’s moods
Infants can recognize each
other's emotions by five months of age, a new study from Brigham Young
University has
found.
"Newborns can't verbalize to their mom or dad that they are hungry or tired, so the first way they communicate is through affect or emotion," said psychology professor Ross Flom.
"Thus it is not surprising that in early development, infants learn to discriminate changes in affect."
Infants can match emotion in adults at seven months and familiar adults at six months. In order to test infant's perception of their peer's emotions, Flom and his team of researchers tested a baby's ability to match emotional infant vocalizations with a paired infant facial expression.
"We found that 5 month old infants can match their peer's positive and negative vocalizations with the appropriate facial expression," says Flom. "This is the first study to show a matching ability with an infant this young. They are exposed to affect in a peer's voice and face which is likely more familiar to them because it's how they themselves convey or communicate positive and negative emotions."
In the study, infants were seated in front of two monitors. One of the monitors displayed video of a happy, smiling baby while the other monitor displayed video of a second sad, frowning baby. When audio was played of a third happy baby, the infant participating in the study looked longer to the video of the baby with positive facial expressions. The infant also was able to match negative vocalizations with video of the sad frowning baby. The audio recordings were from a third baby and not in sync with the lip movements of the babies in either video.
"These findings add to our understanding of early infant development by reiterating the fact that babies are highly sensitive to and comprehend some level of emotion," says Flom. "Babies learn more in their first 2 1/2 years of life than they do the rest of their lifespan, making it critical to examine how and what young infants learn and how this helps them learn other things."
The study has been published in the academic journal Infancy.

Coffee can help you loose
weight: study
Coffee could help one live longer and lose weight, claimed
a new study. Scientists at Griffith University are currently studying, if
drinking coffee helps people lose weight by suppressing their appetite,
reported AAP news agency.
The results of early trials will come as good news to
coffee addicts who are also looking to shed weight. Participants were given
either normal coffee, decaffeinated coffee, or a caffeine tablet with breakfast
and their appetites were monitored until lunch.
"So far, we're seeing a decrease in hunger and an increase
in fullness in the caffeinated coffee condition, a trend we're not observing
with decaffeinated coffee or caffeine alone," Griffith University doctoral
student Matt Schubert said in a statement.
"This may be important for weight control, as any decrease
in appetite could help reduce food intake. Coffee has already been shown to
reduce the risk of diabetes, stroke, some cancers, mental illness and overall
mortality," he said.
