Physical distractors are always present and rarely understood
Our environment is much more important to how we feel and react than we often think.⑼ Particularly is this true of the effect of physical distractors on mental tasks.⑽ One research report has shown that comprehension and retention of reading were decreased when students listened to lively music. However， rate of reading was not affected ， so that many students were not aware that they were affected by the background distractor. Another study found that the ability to recall accurately was affected by distracting conditions. Most of the evidence indicates that noise affects adversely higher mental task output. Still， the effect of distractors is seldom fully appreciated by students.

ROUTINE AND REASONING TASKS ARE AFFECTED DIFFERENTLY BY DISTARCTORS
Many routine tasks can be performed with distraction in the background with little or no adverse effect on output. Most students have found this fact to be true from their own experience. They may have had high school homework which was drill or merely copying assignments. It was possible to do such work with the latest recordings or the television set playing in the background. In time such students began to feel certain that they could do all work - routine or problem- solving -in the same manner.⑾ The evidence indicates the contrary conclusion.

EXCEPTIONS MAY MISLEAD YOU
Typically when students are faced with the evidence on distractors the argument is given that their cousin， friend， or classmate can study in “Grand Central Station.”⑿ And he makes “all A‘s” too！ There is evidence， of course. That motivation plays an important role in overcoming the effects of distractors and that there are considerable differences in individual spans of attention. ⒀Either of these factors could account for some individuals being able to do well using inefficient methods. ⒁The fact that some exceptional people do well under adverse conditions scarcely justifies your assuming that you are exceptional in the same manner. ⒂Your chances of success are higher if you avoid the distractors which are known to hinder the typical student.
