eLife:激励可无意识的影响我们的视觉经历

来自UCL的一项新研究发现,微妙的、无意识的激励增加——表现为心跳加快和瞳孔放大,可塑造我们视觉经历的信心。该研究已发表于eLife,研究人员研究了无意识激励对自信的人在看到自己完成简单的任务后的感觉。研究共招募了29名志愿者,所有参与者观看屏幕上一个移动的点,判断这些点是否移动到左边或右边,并记录其对自身判断的自信率。所有参与者所不知道的是,在完成这一简单任务期间,可能会有令人不愉快的图像突然出

来自UCL的一项新研究发现,微妙的、无意识的激励增加——表现为心跳加快和瞳孔放大,可塑造我们视觉经历的信心。该研究已发表于eLife,研究人员研究了无意识激励对自信的人在看到自己完成简单的任务后的感觉。

研究共招募了29名志愿者,所有参与者观看屏幕上一个移动的点,判断这些点是否移动到左边或右边,并记录其对自身判断的自信率。所有参与者所不知道的是,在完成这一简单任务期间,可能会有令人不愉快的图像突然出现在屏幕上,由此可加快参与者的心率,并使其瞳孔扩张增加。虽然当这些点噪声加大且更难检测时志愿者的信心会降低,但是这种效应是随着增加的激励而抵消。

该研究结果表明,机体生理状态的微妙的、无意识的变化可影响我们对不确定性事务的感知。有趣的是,研究人员发现,不仅信心与心跳有关,而且人为地增加激励实际上也会引起参与者表现为他们对其视觉体验的质量视而不见。这表明,我们有意识的反思能力较以前所认为的体现的更多。

由于疾病(如抑郁和焦虑)或与激励的改变状态有关,我们的研究结果则提高了这些患者感知不切实际的确定或不确定世界的可能。

人类大脑识别图像仅13毫秒

美国研究人员发现人类大脑“解析”眼睛所看图像仅需13毫秒。 据英国每日邮报报道,人们或许会认为一瞬间人类无法识别十几张一闪而过的照片,但目前神经系统科学家发现人类大脑识别一张图像仅需13毫秒。 美国研究人员发现人类大脑仅13毫秒便能识别和理解一张照片,并在实验中首次证实这种大脑快速处理能力,该处理速度比之前研究发现的大脑识别图像速度快8倍。当测试者观看6张或者12张照片时,

Proc Biol Sci:人类嗅觉信息可以引导视觉注意
