Imagine meeting a friend for lunch at a popular restaurant. Quite likely there is music playing in the background, as well as a babble of voiced coming from the people eating lunch at nearby tables. To make matters worse, the couple seated at the table next to you, whom you do not know, are discussing an event that took place at your daughter's school, and may have involved her. As a result, you find it very difficult to concentrate on what your friend is saying for two reasons. First, the shear volume of sound makes it difficult to hear your friend's voice. Second, neighboring conversations that are intelligible (you can actually make out what they are saying) interfere with your attempts to remain focused on what your friend is saying because bits and pieces of their conversations keep intruding into your consciousness. Hence, your ability to communicate in such situations will depend on how well your auditory system can extract your friend's voice from the volume of noise in the background, as well as your ability to ignore any bits of other people's conversation that are interfering with your concentration at a cognitive level. The goal of this grant is to understand how people manage to function in such environments. Previous research has shown that people who are listening in their second language find such situations much more difficult than those listening in their first language. This is a serious problem in Canada given the number of people for whom English or French is a second language. The research proposed here is aimed at finding out the reasons for this added difficulty with the eventual goal of ameliorating the difficulties that people who are functioning in their second language experience.

想象一下，在一家受欢迎的餐厅与朋友共进午餐。 很可能有音乐在背景中播放，以及从附近桌子上吃午餐的人发出的声音。 更糟糕的是，坐在你旁边桌子上的一对你不认识的夫妇正在讨论发生在你女儿学校的一件事，可能和她有关。 首先，声音的剪切音量使你很难听到朋友的声音。第二，周围的对话是可以理解的（你实际上可以分辨出他们在说什么），这会干扰你集中注意力听朋友在说什么的努力，因为他们的对话片段会不断侵入你的意识。 因此，在这种情况下，你的沟通能力将取决于你的听觉系统如何从背景噪音中提取你朋友的声音，以及你是否有能力忽略任何干扰你注意力的其他人的谈话。 这项资助的目标是了解人们如何在这样的环境中发挥作用。以前的研究表明，用第二语言听的人发现这种情况比用第一语言听的人要困难得多。这在加拿大是一个严重的问题，因为有很多人把英语或法语作为第二语言。 本文提出的研究旨在找出这种额外困难的原因，最终目标是改善人们在第二语言中遇到的困难。
