Characteristics of sustaining attention in a gradual-onset continuous performance task [0.03%]
渐进起效的持续性能任务中的注意力持久性特征分析

Continuous performance tasks are frequently associated with a vigilance decrement, particularly when target events are rare and after prolonged time on task. Here we characterized the time course of a performance decrement that happens more...
How visual experience and task context modulate the use of internal and external spatial coordinate for perception and action [0.03%]
视觉经验和任务情境如何调节感知和行为中内在空间坐标和外在空间坐标的使用

Virginie Crollen et al.
Recent studies proposed that the use of internal and external coordinate systems for perception and action may be more flexible in congenitally blind when compared to sighted individuals. To investigate this hypothesis further, we asked con...
Anticipatory mechanisms influence articulation in the form preparation task [0.03%]

In the form preparation task, participants verbally produce words in small sets, which either overlap on an early phonological fragment or contrast on that fragment. A canonical account of word-form encoding assumes a sequential phonologica...
Modeling accuracy, response time, and bias in continuous orientation judgments [0.03%]

Despite the prevalence of real-world and laboratory tasks where people select among many options, cognitive models have traditionally focused on choices among small sets of alternatives. This has resulted in theoretical and empirical gaps i...
Is there a shape to the attention spotlight? Computing saliency over proto-objects predicts fixations during scene viewing [0.03%]
注意力的聚焦区域是有形状的吗？基于图式物体计算显著性预测场景观看时的注视点位置

Attention controls the selective routing of visual inputs for classification. This "spotlight" of attention has been assumed to be a Gaussian, but here we propose that this routing occurs in the form of a shape. We show that a model of atte...
Evidence for second-order singleton suppression based on probabilistic expectations [0.03%]

Decades of research in attention have shown that salient distractors (e.g., a color singleton) tend to capture attention. However, in most studies, singleton distractors are just as likely to be present as absent. We therefore have little k...

A central goal in research on visual perception is to understand how the visual system represents the shapes of objects. According to many theorists, axes defined on the basis of object geometry provide a coordinate system for representing ...

Recent sensory history affects subsequent experience. Behavioral results have demonstrated this effect in two forms: repeated exposure to the same sensory input produces negative aftereffects wherein sensory stimuli like those previously ex...
Sensitivity to configural information and expertise in visual word recognition [0.03%]
构配置信息的敏感性与视觉词识别中的专家效应

Alan C-N Wong et al.
Holistic processing has been regarded as a marker of perceptual expertise for many object categories. However, visual word processing, a common form of perceptual expertise in the population, is traditionally considered part-based instead o...
Grasp planning for object manipulation without simulation of the object manipulation action [0.03%]
无需模拟操作动作的抓取规划以实现物体操控
Oliver Herbort,Wladimir Kirsch,Wilfried Kunde
Oliver Herbort
When an object is grasped, the grasp is usually adapted to upcoming object manipulations. We tested the hypothesis that grasp planning for object manipulation is based on simulations of body movements that could implement intended object ma...
