The Myth of the Brain as a Video Camera

Before we discuss what current research tells us about memory and recall, it may be helpful to address a common misconception that emerged from the work ofCanadian neurosurgeon Wilder Penfield in the 1930s and 1940s. Penfield reported that during surgery, an electrical stimulation of the temporal lobe produced episodes of recall, almost like seeing movie clips. Many concluded that the brain ?videotaped? life, and to remember things, our memories simply needed to be prompted. But these episode...

 The Babbling Stage of Infancy

It is interesting and perhaps surprising to realize that most mammals lack a capacity for complex vocal learning of this sort. Current research suggests that aside from humans, only marine mammals (whales, dolphins, seals), bats, and elephants have it. Among primates, humans appear to be the only species that can hear new sounds in the environment and then reproduce them. Our ability to do this seems to depend on a babbling stage during infancy, a period of vocal playfulness as instinctual as...

 Parenting Research is Associative, Not Causal

Even if all brains were wired identically and all parents behaved in a cookie-cutter fashion, a great deal of current research would still be flawed (or, at best, preliminary). Most of the data we have are associative, not causal. Why is that a problem? Two things can be associated without one causing the other. For example, it is true that all children who throw temper tantrums also urinate—the association is 100 percent—but that doesn’t mean urination leads to temper tantrums. The ideal r...
