Environmental Noise May Have a Negative Impact on Human Cognitive Abilities
Environmental noise may have a negative impact on our cognitive abilities. In contrast, competition may attenuate the negative effects of noise on cognitive abilities. Further, noise and competition may interact in their effect on cognitive abilities. In this study, researchers attempted to determine if environmental noise reduced the performance of participants in a visual task. Specifically, participants were asked to locate objects in a picture, and then exposed to noise alone, competition alone, or noise and competition, or no noise or competition. Competition was defined as the presence of a $20 award, while noise was defined as white noise.
Participants were timed in the cognitive task.
There is compelling evidence that noise can alter human cognitive abilities. A recent study published in Psychological Science demonstrates the potentially negative effect of noise on human cognitive processing. The study of 326 children showed that those who were exposed to the noise of jet aircraft flying overhead had impaired reading ability and short-term memory. The authors note that the deleterious effects of noise can be reduced in a quite environment (Hygge, Evans & Bullinger, 2002)....
Distraction vs. Competition on Performance People work best in a quiet environment. A little competition is a good thing. These two tenets have been the pillars upon which the modern school and office have been built. A recent study conducted in a Psychology Research Methods Lab seeks to determine which of these conditions has a greater effect on individual performance. Several studies have shown that the introduction of noise into an
