THE EXTENDED MIND

THE POWER OF THINKING OUTSIDE THE BRAIN

It helps to have a brain to think with, but Paul capably shows that there’s much more to the process than all that.

A look at the science behind the parts of our consciousness and ideation that lie outside the body.

Marshall McLuhan famously called media “the extensions of man.” Science writer Paul updates this notion to battle what researchers have called neurocentric bias “and our corresponding blind spot for all the ways cognition extends beyond the skull.” We acquire much information via the processing of the senses into mental furrows and synapses, but we also have other avenues of thinking: for instance, what Paul describes as a well-developed “interoceptive sense.” This involves teaching ourselves how to become more aware of what’s happening in our bodies through an exercise called the “body scan,” imagining that breath occurs elsewhere in the body than in the pulmonary tract. Mindfulness meditation also extends awareness of the parasympathetic nervous system, itself a source of information. Paul examines the well-known effects of walking on mind improvement and the use of gesture to both build memory and to pull words out of the air (or mental databanks, more properly) as we speak. The author uses recently deceased Zappos founder Tony Hsieh as a model for someone who strived to forge “a sense of unity and cohesion among the firm’s employees,” re-creating the as-oneness he experienced at drug-fueled raves. The mind can be expanded, and not necessarily by drugs, by compartmentalizing it so that others store information for us. Intriguingly, Paul explores an experimental learning technique in which students are divided into groups and then assigned to learn a segment of a topic, later combining the information they’ve mastered in an example of “a transactive memory system.” Though less fluent than other popular-science writers such as Malcolm Gladwell and Elizabeth Kolbert, Paul does a good job of drawing together the many extensions of mind that surround us, exhorting readers to “re-spatialize the information we think about.”

It helps to have a brain to think with, but Paul capably shows that there’s much more to the process than all that.

HOW DO APPLES GROW?

A straightforward, carefully detailed presentation of how ``fruit comes from flowers,'' from winter's snow-covered buds through pollination and growth to ripening and harvest. Like the text, the illustrations are admirably clear and attractive, including the larger-than-life depiction of the parts of the flower at different stages. An excellent contribution to the solidly useful ``Let's-Read-and-Find-Out-Science'' series. (Nonfiction/Picture book. 4-9)

MASTERY

Readers unfamiliar with the anecdotal material Greene presents may find interesting avenues to pursue, but they should...

Greene (The 33 Strategies of War, 2007, etc.) believes that genius can be learned if we pay attention and reject social conformity.

The author suggests that our emergence as a species with stereoscopic, frontal vision and sophisticated hand-eye coordination gave us an advantage over earlier humans and primates because it allowed us to contemplate a situation and ponder alternatives for action. This, along with the advantages conferred by mirror neurons, which allow us to intuit what others may be thinking, contributed to our ability to learn, pass on inventions to future generations and improve our problem-solving ability. Throughout most of human history, we were hunter-gatherers, and our brains are engineered accordingly. The author has a jaundiced view of our modern technological society, which, he writes, encourages quick, rash judgments. We fail to spend the time needed to develop thorough mastery of a subject. Greene writes that every human is “born unique,” with specific potential that we can develop if we listen to our inner voice. He offers many interesting but tendentious examples to illustrate his theory, including Einstein, Darwin, Mozart and Temple Grandin. In the case of Darwin, Greene ignores the formative intellectual influences that shaped his thought, including the discovery of geological evolution with which he was familiar before his famous voyage. The author uses Grandin's struggle to overcome autistic social handicaps as a model for the necessity for everyone to create a deceptive social mask.

Readers unfamiliar with the anecdotal material Greene presents may find interesting avenues to pursue, but they should beware of the author's quirky, sometimes misleading brush-stroke characterizations.
