Chapter 2 infographic image description

The title of the infographic is, Thinking Critically About: Using More Than 10 Percent of Our Brain

The Learning Objective Question reads, Do we really use only 10 percent of our brain?

The infographic is divided into four numbered sections. The first section reads, 1. Electrically probing an association area leads to no observable response. The illustration shows a doctor probing a person’s brain. The probe is connected by a wire to a computer monitor that shows the outline of the person’s head and brain with a large question mark superimposed over the empty brain.

An arrow points from Section 1 to Section 2. The second section reads, 2. This vast association area open quotes silence close quotes has led to the false claim that we really use only 10 percent of our brain – open quotes one of the hardiest weeds in the garden of psychology close quotes. (Footnote: McBurney, 1996, p. 44.)

An arrow points from Section 2 to Section 3. The third section reads, 3. Is there really a 90 percent chance that a bullet to your brain would land in an unused area? The illustration shows a bullet shooting toward a human brain.

An arrow points from Section 3 to Section 4 where the answer to the Section 3 question reads, No.

An arrow points from the word No. to the Section 4 text which reads, Brain-damaged animals and humans bear witness: Association areas interpret, integrate, and act on sensory information and link it with stored memories. More intelligent animals have larger association areas. The corresponding illustration shows the motor areas, association areas, and somatosensory areas in the brains of a rat, a cat, a chimpanzee, and a human.
