...studv at the Pasteur Institute in France where films had been made and slowed down 100 times. The Physarum pulse was seen to have a period of about 45 seconds. Dr. Seifriz rejects the older theories attributing protoplasmic movement to surface tension, electric potentials, etc. "I ask the reader," he wrote recently in Science, "merely to admit that protoplasm is alive, for in so doing, he tacitly grants that it exhibits irritability, in other words, nervous response...
Reading eyes do not move continuously from left to right. They hop. The number of words they grasp in one hop is called the span of recognition. This span for the average efficient college reader is 1.2 words; a very few persons can grasp as many as five or six words at once. At the end of the hop there is a pause, while the words register on the brain; 94% of reading time is spent in these "fixations." Sometimes the eye goes back over words it has already scanned. These are regressions. To read rapidly it is necessary...
First step in Dr. Center's clinic is to measure hops, fixations and regressions with an ophthalmograph. which takes motion pictures of a reader's eye movements. The resulting picture looks like sets of stairs, recording the eye's stops and jerks. If the reader is efficient, the stairs are regular...
...create a regular rhythm of reading is the task of another machine, the metronoscope, which exposes one, two or three words at a time to the reader through a narrow window. It trains the reader to extend his span to two words, cuts the fixation time. Because the words move out of sight as fast as they are read, it eliminates regressions. The speed of the machine is gradually increased to raise the reader's speed...
...Fastest reader ever tested, an 8-year-old high-school boy who evidently had an unusually large macula (a yellow spot in the retina, most sensitive point of vision), in one test read 2,202 words a minute with excellent comprehension...
