该EmoCogMeter是与MicroMovie传媒有限公司（http://www.micromovie.com）合作开发的。

1。主题我们招募了541心理和体细胞的健康男性和女性受试者（年龄44.47±9.41，范围为18-89岁;智商113.90±12.73）。所有受试者在母语水平说德语。该研究是根据赫尔辛基宣言的最新版本，并通过德国心理学会的机构审查委员会。所有受试者签署知情同意书前筛查，并报销参与。 2。研究设计该EmoCogMeter，一个iPad的应用程序，包括7个神经心?...

本研究的主要目的是评估在调查的年龄对整个生命周期认知功能影响的平板电脑的应用程序的可用性。由于假设，受试者表现出最神经域的年龄相关的下降。对于某些认知功能，如记忆广度，工作记忆准确性和选择性注意，会出现下降以后的生活中发生，因为它是比较中年和老年人的主体时，仅观察到。其他认知功能，主要是反应潜伏期，持续关注，处理速度和执行功能似乎已经受到影响中年。?...

人体衰老与认知功能下降在所有领域有关，但可能会特别明显与前额叶皮层和内侧颞叶，如工作记忆（WM），情景记忆和执行功能相关的功能，（贝克曼等。1 ，Brehmer 等。2，盛等人。3，西4）。相应地，脑成像研究表明，体积减少是最突出的前额和mediotemporal区域（拉兹等 5,6）和内和之间的这些区域是改变的功能可能有助于与年龄相关的认知变化（Sander 等人 7 ，公园和路透社-洛伦茨8）。分子影像学研究表明，与年龄相关的多巴胺的损失可能是减值的多个认知任务的功能强大的介质（贝克曼等[9，10;。Erixon-Lindroth等[11] </sup&gt;，沃尔科夫等人 12）。有相当多的证据表明，在老年感知和认知能力可能受情绪刺激增强。老年人与有关的注意措施积极效价的刺激有更好的表现的倾向，识别和情绪记忆增强，被称为与年龄相关的积极影响（查尔斯等人 13，马瑟和骑士14，Löckenhoff和卡斯特森15 ，Grühn 等 16 Isaacowitz 等 17），可能反映了激励目标，生命的尽头差异接近（卡斯特森和Löckenhoff18）。 认知功能神经心理学测试通常是由对工作站纸和铅笔测试或基于计算机的测试手段进行的任何及测试年长者时，可能会很困难。首先，削弱运动技能可能会限制使用的PA每次和纸笔测试，其次，年长者往往不熟悉键盘，鼠标垫，或基于计算机的神经心理学测试过程中施加其它输入设备。因此，年长者常表现不佳的动机或合规过程中神经心理测试，这可能会损害性能，并降低了结果的有效性。此外，纸和铅笔测试以及在工作站上基于计算机的测试要求实验者的指令和反馈的永久考勤以及对结果的文件，然后再很少转移到一个数据库，因此只对一个非常数量的人的限制。因此，转让结果时，这种“传统”的方式来神经心理测试联系起来相当的人力资源增加了出错的概率，限制数据访问，并减缓了工作流程。 我们的目的是测试本身的调查，平板电脑的应用程序贝拉尔神经心理学领域。我们使用一个iPad应用程序作为我们推测，这样一个简单的工具可能是一个快速而有效的方法来筛查和在临床和门诊追踪认知缺陷。不论年龄大小，应启用科目来执行任务，而无需从实验者指令或反馈，应该能够完成测试。不论年龄大小，应启用科目不从实验者指令或反馈执行的任务。我们推测，该触控板会允许一个更直观的使用比其他反应设备（ 如鼠标垫或键盘），特别是年长者，谁不熟悉电脑。提高合规性和动力性能的任务可能会增加结果的有效性，而对于实验者利益应包括标准化的和节省时间的测试程序，测试结果的安全传输到数据存储和ANALY的数据库和便利化SIS。

本研究的主要目的是评估调查对认知功能在整个生命周期的378名健康受试者（年龄范围18-89岁）样品中的年龄效应的平板电脑的应用程序（EmoCogMeter）的可用性。与以前的研究结果，我们发现在多种神经心理学领域（记忆力，注意力，执行功能）的与年龄有关的认知衰退，从而证明我们的平板电脑的应用程序的可用性。无论电脑前的经验，所有年龄组的受试者能够在没有实验者指令或反馈执行的任务。增加的动力和符合证明是有益的任务绩效，从而无形中增加了结果的有效性。我们有前途的研究结果强调的检测和监控的认知功能障碍的平板电脑的应用程序的重要的临床和实用潜力。

从19个科目的数据不能因技术问题记录。所有剩余的受试者（n = 522）完成了测试和聚为3个年龄组（年轻：18-30岁;中年人：31-59岁;岁：60-89岁）。在这些群体参加者按照性别和智商导致在N = 378样本大小（ 见表1）匹配。在3个年龄组的所有神经心理测验的性能列于表2。 学习和记忆 记忆广度 有年龄对数?...
