Neural Bottleneck Found That Thwarts Multi-tasking
-
The two tasks consisted of pressing the appropriate computer key in response to hearing one of eight possible sounds and uttering an appropriate syllable in response to seeing one of eight possible images. Different senses and motor responses were enlisted in order to ensure that any interference between the two tasks was not specific to a particular sensory or motor modality, but instead originated at a central information-processing bottleneck.
-
The results revealed that the central bottleneck was caused by the inability of the lateral frontal and prefrontal cortex, and also the superior frontal cortex, to process the two tasks at once.

Multi-tasking Adversely Affects Brain's Learning, UCLA Psychologists Report
-
Participants in the study, who were in their 20s, learned a simple classification task by trial-and-error. They were asked to make predictions after receiving a set of cues concerning cards that displayed various shapes, and divided the cards into two categories. With one set of cards, they learned without any distractions. With a second set of cards, they performed a simultaneous task: listening to high and low beeps through headphones and keeping a mental count of the high-pitch beeps. While the distraction of the beeps did not reduce the accuracy of the predictions -- people could learn the task either way -- it did reduce the participants' subsequent knowledge about the task during a follow-up session.
-
When the subjects were asked questions about the cards afterward, they did much better on the task they learned without the distraction. On the task they learned with the distraction, they could not extrapolate; in scientific terms, their knowledge was much less "flexible."

Public Schools Outperform Private Schools in Math Instruction
-
Of the five factors, school size and parental involvement “didn’t seem to matter all that much,” Lubienski said, citing a weak correlation between the two factors as “mixed or marginally significant predictors” of student achievement.
They also discovered that smaller class sizes, which are more prevalent in private schools than in public schools, significantly correlate with achievement.
-
The schools with the smallest percentage of certified teachers – conservative Christian schools, where less than half of teachers were certified – were, not coincidentally, the schools with the lowest aggregate math test scores.

Do Doodle: Doodling Can Help Memory Recall
-
"If someone is doing a boring task, like listening to a dull telephone conversation, they may start to daydream," said study researcher Professor Jackie Andrade, Ph.D., of the School of Psychology, University of Plymouth. "Daydreaming distracts them from the task, resulting in poorer performance. A simple task, like doodling, may be sufficient to stop daydreaming without affecting performance on the main task."
