Seeing Through Distraction

The reason that the unusual fonts are effective is that it causes us to think more deeply about the material,” a co-author of the study, Daniel M. Oppenheimer, a psychologist at Princeton, wrote in an e-mail. “But we are capable of thinking deeply without being subjected to unusual fonts. Think of it this way, you can’t skim material in a hard to read font, so putting text in a hard-to-read font will force you to read more carefully.

Ancient life was all silence. In the nineteenth century, with the invention of the machine, Noise was born. Today, Noise triumphs and reigns supreme over the sensibility of men. For many centuries life went by in silence, or at most in muted tones. The strongest noises which interrupted this silence were not intense or prolonged or varied. If we overlook such exceptional movements as earthquakes, hurricanes, storms, avalanches and waterfalls, nature is silent. …. This musical evolution is paralleled by the multiplication of machines, which collaborate with man on every front. Not only in the roaring atmosphere of major cities, but in the country too, which until yesterday was totally silent, the machine today has created such a variety and rivalry of noises that pure sound, in its exiguity and monotony, no longer arouses any feeling.

Many education researchers and practitioners believe that reducing extraneous cognitive load is always beneficial for the learner. In other words, if a student has a relatively easy time learning a new lesson or concept, both the student and instructor are likely to label the session as successful.

That sounds reasonable, right? Shouldn’t learning be as easy and effortless as possible? Unfortunately, this assumption turns out to be mostly wrong, as numerous studies have found that making material harder to learn — what the researchers call disfluency — can actually improve long-term learning and retention:

There is strong theoretical justification to believe that disfluency could lead to improved retention and classroom performance. Disfluency has been shown to lead people to process information more deeply, more abstractly, more carefully, and yield better comprehension, all of which are critical to effective learning.

At every instant, there is more than the eye can see, more than the ear can hear, a setting or a view waiting to be explored. Nothing is experienced by itself, but always in relation to its surroundings, the sequence of events leading up to it, the memory of past experiences.
