Faces communicate information from which we can quickly infer the gender, the state of mind, the age and the identity of our peers, and adjust our behavior accordingly. In my past research funded by NSERC Discover Grants, I have examined how the human brain performs these feats using a combination of psychophysical, neuropsychological, brain imaging and computational modeling methods. One aspect that I've become increasingly interested in is the correlation between the strategies employed by individuals to resolve these tasks and different dependant measures such as task performance. The main goal of this research proposal is to go beyond such correlational links and establish causal links. Specifically, I propose to induce specific visual strategies in subjects and to examine the impact of this experimental manipulation on the relevant dependant variables. To illustrate, I recently discovered that use of the eye on the left side of face stimuli during a gender discrimination task was positively correlated with performance, while utilization of the eye on the right side of face stimuli was not correlated with performance. Following this, I have induced via operant conditionning the use of the left eye in one group of subjects and the use of the right eye in another group of subjects. I found that gender discrimination performance improved more in the former subject group than in the latter. Therefore, in this task, the use of the left eye is causally linked with performance. This research proposal has three specific aims: 1) Test and develop methods for inducing the use of specific visual information. 2) Examine the nature of the links between information usage and various dependent measures. 3) Reveal the visual strategy of observers with outstanding face recognition abilities and induce this strategy in observers with extremely poor face recognition abilities. These advances should also lead to a means for individuals with jobs requiring strong face processing such as police officers, security agents, and customs officials to improve their abilities. Thus, the outcomes of this project are expected to fundamentally advance our understanding of key issues in perception while also having a valuable impact on health, well-being, and national security.

面孔传达信息，我们可以从中快速推断出同龄人的性别、精神状态、年龄和身份，并相应地调整我们的行为。在我过去的研究中，由NSERC发现赠款资助，我已经研究了人类大脑如何使用心理物理学，神经心理学，大脑成像和计算建模方法的组合来执行这些壮举。我越来越感兴趣的一个方面是个体解决这些任务所采用的策略与不同的依赖性措施（如任务绩效）之间的相关性。本研究提案的主要目标是超越这种相关性联系，建立因果联系。具体来说，我建议诱导特定的视觉策略的主题，并检查此实验操作的影响，对相关的因变量。为了说明这一点，我最近发现，在性别歧视任务中，在面部刺激的左侧使用眼睛与表现呈正相关，而在面部刺激的右侧使用眼睛与表现无关。在此之后，我通过操作性条件反射诱导一组受试者使用左眼，另一组受试者使用右眼。我发现，性别歧视的表现改善更多的前主题组比后者。因此，在这项任务中，左眼的使用与表现有因果关系。本研究有三个目的：1）测试和开发诱导特定视觉信息使用的方法。2)检查信息使用和各种依赖措施之间的联系的性质。3)揭示了具有优异面孔识别能力的观察者的视觉策略，并归纳了极差面孔识别能力的观察者的视觉策略。这些进步也应该为那些需要强大面部处理能力的工作人员（如警察、安全人员和海关官员）提供一种提高能力的手段。因此，该项目的成果有望从根本上促进我们对感知中关键问题的理解，同时对健康，福祉和国家安全产生宝贵的影响。
