BACKGROUND This study explored whether the high-resolution representations created by visual working memory (VWM) are constructed in a coarse-to-fine or all-or-none manner. The coarse-to-fine hypothesis suggests that coarse information precedes detailed information in entering VWM and that its resolution increases along with the processing time of the(More)
Two accounts prevail for the ERP component contralateral delay activity (CDA). One is that CDA tracks the number of objects stored in visual working memory (VWM), the more objects the higher amplitude (object number account). The other is that CDA reflects the maintained information load (information load account), the higher load the higher amplitude. The(More)
Although the mechanisms of visual short term memory (VSTM) are extensively investigated in the recent decade, how we compare the representation stored in VSTM to the perceptual input to detect and process the mismatch information remains largely unclear. The current study explored whether there is an ERP component tracking the mismatch process in VSTM by(More)
The flash-lag effect is a robust visual illusion in which a flash appears to spatially lag a continuously moving stimulus, even though both stimuli are actually precisely aligned. Some research has been done to test how visual information has been integrated over time. The position integration model suggests motion integration is a form of interpolation of(More)
Previous studies suggested that ERP component contralateral delay activity (CDA) tracks the number of objects containing identity information stored in visual short term memory (VSTM). Later MEG and fMRI studies implied that its neural source lays in superior IPS. However, since the memorized stimuli in previous studies were displayed in distinct spatial(More)
Recently, researchers have begun to investigate how nonspatial perceptual information is extracted into visual working memory (VWM), focusing particularly on object-based encoding (OBE). That is, whenever even one feature-dimension is selected for entry into VWM, the others are also extracted automatically. While there is evidence supporting robust OBE in(More)
In daily life, visual working memory (VWM) typically works in contexts in which people make frequent saccades. Here, we investigated whether people can effectively control the allocation of VWM when making a saccade. Subjects were required to make an intervening saccade in the process of a memory task. The saccade target was either a to-be-remembered item(More)
Anger is a negative emotion associated with approach motivation and may influence children's attention preference. Three experiments examined the effect of anger on the attentional biases accompanying reward versus punishment cues in Chinese 5- and 6-year-olds. Experiment 1 tested children who were prone to report angry feelings in an unfair game.(More)
In this study, we investigated whether or not the reconfiguration of a set task could modulate the efficiency of feature search. In Experiment 1, target set size was manipulated. The results revealed that enumerating targets defined by color yields a much steeper slope when executed simultaneously with a discrimination task than when done singly. However,(More)
