With the support from Major Research Instrumentation, the eye-tracking system (SR Research EyeLink 1000 Plus) will be acquired. The project is built upon the interdisciplinary team of one visual cognition researcher and six decision science researchers at Drake University (Des Moines, Iowa). By integrating the well-established techniques in the visual cognition field, the system enables decision science researchers in the team (economics, marketing, accounting, actuarial science, information management) to examine cognitive mechanisms involved in decision-making processes with a finer resolution than eye-tracking methods typically employed in the fields of decision science research. The system allows researchers to investigate information-processing mechanisms that operate prior to conscious response. The project is designed not only to make real-world application of visual cognition research more accessible to students, but also to introduce students in the decision science field to a scientific approach of dealing with novel data acquired through systematic empirical investigations. Because decision science is uniquely concerned with how individuals make optimal choices based on available information, some decision scientists work exclusively with pre-existing data. The research team also recognizes that popular methods of recruiting students to the research lab through a single department has its limitation to reach out to underrepresented student populations. To promote diversity, equity and inclusion, multiple mechanisms to recruit and support a wide range of students are built in.The questions pursued in the present project range across (1) how much attentional control one can exert during memory maintenance (visual cognition), (2) how different ways of presenting the nutrition information shapes one's decision-making process of food choice (marketing), (3) how the lack of opportunities affects one's cognitive mechanisms differently from resource scarcity (economics: psychology of poverty), (4) how a popular survey method (i.e., the choice experiment) can be optimized with powerful perceptual and cognitive manipulations (environmental economics), (5) how visual features of the voluntarily disclosed financial information can minimize the chance that the investors can be misled (accounting), (6) when individuals tend to stop processing the massive amount of disclosure information, and how visualization of the difficult-to-understand section would ease one's comprehension of the product (actuarial science), and (7) how search efficiency of the crucial information can be enhanced in the e-commerce context (information management).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在Major Research Instrumentation的支持下，将收购眼动跟踪系统（SR Research EyeLink 1000 Plus）。 该项目建立在德雷克大学（爱荷华州得梅因）的一名视觉认知研究人员和六名决策科学研究人员的跨学科团队基础上。 通过整合视觉认知领域的成熟技术，该系统使团队中的决策科学研究人员（经济学，市场营销，会计，精算学，信息管理）能够以比决策科学研究领域通常采用的眼动跟踪方法更精细的分辨率来检查决策过程中涉及的认知机制。 该系统允许研究人员研究在有意识反应之前运作的信息处理机制。该项目的目的不仅是使学生更容易接触到视觉认知研究的实际应用，而且还向决策科学领域的学生介绍了处理通过系统的实证调查获得的新数据的科学方法。 由于决策科学只关注个人如何根据现有信息做出最佳选择，因此一些决策科学家只使用预先存在的数据。 研究小组还认识到，通过单一部门招募学生到研究实验室的流行方法在接触代表性不足的学生群体方面存在局限性。 为了促进多样性、公平性和包容性，建立了多种机制来招募和支持各种各样的学生。本项目所追求的问题包括：（1）在记忆维持过程中，一个人可以施加多少注意力控制（2）不同的营养信息呈现方式如何塑造一个人的食物选择决策过程（市场营销），（3）缺乏机会如何影响一个人的认知机制不同于资源稀缺（经济学：贫困心理学），（4）如何流行的调查方法（即，选择实验）可以用强大的感知和认知操作来优化（5）自愿披露的财务信息的视觉特征如何最大限度地减少投资者被误导的机会（会计），（6）当个人倾向于停止处理大量的披露信息时，以及难以理解的部分的可视化如何减轻人们对产品的理解（精算学），及（7）如何在电子商贸环境下提高关键资料的搜寻效率该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
