    New preprint with Emma Bsales and . We show that covert attention speeds the N2pc component, providing evidence that attention speeds individuation of a visual target. See thread for a quick summary (1/6)

    I am seeking MA & Ph.D. students, who are interested in memory & attention for my lab at Sabancı University in Istanbul (). I would appreciate it if you can share this link with students who may be interested:

    An important step toward increasing replicability of findings is to increase the reproducibility of methods. Analysis methods can easily be made reproducible by publishing data analysis scripts. But what about data collection methods? 1/n

    Illusion of The Year 2019 Winner It's based on a simple Lissajous curve, but uses clever shading/highlighting to create a 'double-axis' illusion

    In a new preprint (), we model working memory performance over short and long retention intervals. We find that the inability to sustain attention over long retention intervals leads to worse WM performance

    Now in press @ JNeurosci: We show that category learning is associated with rapid, task-dependent, and reversible changes in stimulus-specific sensory representations in human occipitoparietal cortex - as early as V1! With and .

    Special issue of Current Opinion in Psychology: Attention and Perception, is out! 40 articles illustrate the breadth of research in which attention plays a critical role. Thanks to for the fun. TOC here:

    How do memories guide attention? Hippocampus & mPFC represent anticipated attentional states. Also, hippocampal attentional states sync with those in early visual cortex during memory-guided attention. Excited to share our preprint with

    In a new publication, we investigate the impact of task-irrelevant interruption on neural correlates of working memory and attention. Check it out:

    Although attention may not speed the earliest visually evoked responses (indexed by very early visually evoked responses), attention does speed subsequent a subsequent stage of perceptual processing: target individuation (indexed by the N2pc). (6/6)

    We found target-evoked N2pc occurred ~20 ms earlier when the target location was cued, suggesting that attention speeds target individuation. Our findings point to a reconciliation of behavioral and neural results… (5/6)

    To complicate matters further, other work has found little evidence that attention influences the latency of very early visually evoked, suggesting that attention doesn’t speed early sensory processing. So what’s going on? (4/6)

    However, based on behavioral responses alone, it is hard to tell whether attention speeds perceptual processing of the target, or subsequent post-perceptual stages of processing (e.g. decision making or response selection). (3/6)

    It’s long been thought that attention speeds perceptual processing. In support of this idea, evidence from psychophysics (Carrasco and McElree, 2001) has shown that observers can report target information earlier when a target appears at an attended location. (2/6)

    Excited to finally post this pre-print from a collaboration project with , Elisa Pabon, Ed Vogel and Harriet de Wit — we show that THC impairs visual working memory performance and increases mind wandering.

    What does it mean to be an activity-silent representation in short-term memory tasks? We make the case that silent memories are stored in LTM. We draw on evidence that LTM plays a role "WM" tasks, especially when our focus is diverted from remembered items. W/ Ed Vogel
