combining computer game-based behavioural experiments with high-density eeg and infrared gaze tracking

实验范式是宝贵的，只要其刺激的时间和其他参数以及指定和控制，因为它们产生的认知加工有关的数据，生态有效的情况下发生。这两个目标往往是不一致的，以及控制刺激往往过于重复，以维持科目的学习动机。研究用人脑电图（EEG）往往特别敏感，这种生态有效性和实验控制之间的两难：在生理平均值达到足够的信号与噪声的要求大量的冗长的录音会议中反复试验，对个人能力的限制受池和耐心去执行一遍又一遍的任务。这个约束，严重地限制了研究人员调查年轻的人口以及与高度焦虑或注意力异常相关的临床人口的能力。即使成年，非临床各科可能不能够达到的性能或认知参与其典型的水平：其中一个无心的主题实验的任务是多一点的一件苦差事不相同，行为，认知或神经，作为一个生谁是内在动机，并与从事的任务。越来越多的文献表明，在视频游戏中嵌入实验，可以提供一种方式之间之间的这种两难的实验控制和生态效度的角。游戏的叙事提供了一个更真实的环境，任务发生，提高其生态的有效期（Chaytor施密特 - Edgecombe 2003年）。此外，这方面提供了完成任务的动力。在我们的游戏，科目执行各种任务，收集资源，击退海盗，截取通讯或促进外交关系。在这样做时，他们也执行认知任务，包括一个波斯纳注意力转移模式（波斯纳，1980），一个走/不走电机抑制，心理物理学的议案连贯性阈值的任务，嵌入式数字测试（威肯测试， 1950年，1954年）和心灵理论（德威马Perner，1983年）的任务。游戏软件自动记录在日志文件中的游戏刺激和科目的行动和响应，并发送事件代码与生理数据记录同步。因此可以结合游戏与生理的措施，如脑电图或成像与凝视的时刻，时刻跟踪。视线跟踪可以验证科目遵守“行为的任务（例如，固定）和公开的重视实验的刺激，生理觉醒，反映散瞳（Bradley等，2008） 。视线跟踪足够大的采样频率，也可能有助于评估隐蔽的重视反映在microsaccades - 眼球运动太小foveate一个新的对象，但在发病迅速，有相同的关系之间的角距离和峰值速度一样扫视，遍历更远的距离。 microsaccades方向分布相关的（否则）注意隐蔽的方向（Hafed和克拉克，2002年）。
