We often assume that newborn babies can’t do much and that first-time parents
are almost equally inept when it comes to handling them. “Wrong on both counts,”
says Elliott Blass, a psychologist at John Hopkins University. Working with groups of babies who were two horns to two bays old, Blass found that newborns can link one
5 even to another and infer a cause-effect relationship. He reported also that babies are born responsive to certain sounds, ones that parents intuitively make.
In an experiment, babies were taught to associate the taste of sugar- a taste they love- with a tactile stimulus. Blass and his colleagues stroked the babies’ forehead
10 to turn his head and extend his tongue in anticipation of the treat. When their foreheads were stroked but the sugar was withheld, most babies protested by crying.
Next Blass did an experiment to determine if babies could learn to anticipate sugar in response
to an auditory stimulus. Babies were divided into four groups, each receiving the sugar after hearing a specific sound: a click, a ting, a psst or a shhh. A
15 control group got sugar after hearing the sounds at random.
The results took Blass by surprise. They showed that clicking was the only sound that babies learned to associate with the delivery of their sugary treat. “The other sounds just didn’t do it,” says Blass, “The babies in the ting, psst, and shhh groups did not turn their heads toward the sugar any more frequently than those in the control group.”
20 One day, while visiting a maternity ward, Blass noticed that when nursing their babies, mothers made clucking noises similar to the clicking sound used in the experiment.
Apparently even the newest parent does some things right, without reading Dr. Spock.
