Task procedure Request a detailed protocol Each trial commenced with gaze fixation on a central dot (diameter: 0.5° of visual angle/dva, color: yellow) in the middle of a gray (35 cd/m2 maximum luminance) screen. After 500ms, task-irrelevant distractors – full contrast plaids (diameter: 4 dva) – appeared in the center of the screen in an RSVP stream (100ms per stimulus).

Abstract Information held in working memory is remarkably resilient to interference. Yet, distractors containing task-relevant features impact working memory systematically. The neural basis of this interference is poorly understood. Combining behavior with multivariate decoding of human electroencephalography recordings, we show that distractors induce space-specific biases in mnemonic representations.

Abstract The attentional blink reflects a ubiquitous bottleneck with selecting and processing the second of two targets that occur in close temporal proximity. An extensive literature has examined the attention blink as a unitary phenomenon, As a result, which specific component of attention – perceptual sensitivity or choice bias – is compromised during the attentional blink, and their respective neural bases, remains unknown.
