Reception

In 1998, psychologist Arthur Graesser examined components of speech and reading comprehension in ‘real-time’ [link]. Components of comprehension include things like ‘unexpected event-handling’ and ‘outcome-resolution’. They are measured in milliseconds. Using an interactive computer-presentation, he recorded the time students spent at each step. Sort of like a reaction-time study. What he found was counter-intuitive. Comprehension scores were actually higher for students who took longer to process unexpected events in a narrative. Students who spent less time had lower scores. On closer examination, he found they were interpreting events way too quickly. Consequently, they were missing the bridge to ‘explanatory’ events presented elsewhere in the narrative. What this tells me is that receptivity is more important than reaching conclusions while listening to someone speak.

Advantages of ADD

The kind of focused attention ordinarily required in a classroom is not always helpful overcoming obstacles outside the classroom. A wider focus of attention, which is usually associated with ADD, is actually more adaptive according to neuroscientists John Kounios and Mark Beeman [link]. And from what I’ve seen, I believe it ..! They found that when students are more open to distraction, they do better navigating a computer-simulated labyrinth than when they are focused and blocking out distractions (as seen on an fMRI). Students actually see and hear more .. finding their way faster by heuristic than by analytic reasoning. In other words, in many situations, discovering relationships between vague and loosely connected information is more advantageous than step-by-step analysis.
