概括

在非搜索任务中,注意力模板的准备激活对于视觉搜索至关重要. 这表明,主动机制支持视觉选择,而不仅仅是引导人们注意目标.

科学领域:

认知神经科学认知神经科学
视觉感知视觉感知视觉感知

背景情况:

注意型模板表示与任务相关的对象属性,并控制视觉处理的选择性.
之前的研究表明,模板是主动激活的视觉搜索指导.

研究的目的:

调查是否在非搜索任务中发生主动模板激活.
确定准备机制是否仅适用于视觉搜索指导.

主要方法:

使用彩色单元探针测量N2pc组件 (注意力分配标记器).
参与者执行了视觉搜索任务,Go/NoGo任务和形状歧视任务.
在目标显示之间的间隔中,探针闪,以跟踪准备激活.

主要成果:

在视觉搜索任务中,观察到N2pc组件用于目标颜色探针.
在Go/NoGo任务中也发现了重要的N2pc组件.
在形状区分任务中检测到减弱的N2pc组件.

结论:

主动激活特征选择性注意力设置并不仅限于视觉搜索指导.
这些准备机制也存在于不需要指导的视觉选择任务中.
这些发现扩大了对视觉处理中的注意力机制的理解.

Visual System

Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...
