New preprint! Are attentional lapses the result of disengagement or simply response failure? Using EEG, we tested how attention fluctuations impact visual representations in the brain. (1/5) www.biorxiv.org/content/10.6...

Degraded neural representations foreshadow failures of sustained attention
Attention prioritizes relevant information from the environment, but does not do so consistently over time. Instead, we sometimes experience poor attentional states which are characterized by a higher...

🚨📢 Paper alert! Our new paper is out in AP&P! We show that sustaining attention on both rewards and penalties is more effective than focusing on penalties alone—a first step toward a Goal-Competition Theory. @monicarosenb.bsky.social @edvogel.bsky.social link.springer.com/article/10.3...

There's ongoing discourse about whether digital technology is impacting attention spans, but the empirical research does not seem to connect with what is felt by the general public. So, to better understand the perceptions, we examined what was being said on the issue in four relevant subreddits.

1/ To reduce distraction and boost focus, nothing works better than linking performance to rewards 💰 But what about focusing to avoid penalties? Turns out — it works too… just not as much as combining both! Check out our new preprint 👇 w/ Ed Vogel and @monicarosenb.bsky.social
Representation of goal activation in working memory as a function of participant motivation. According to the goal competition hypothesis, goal activation in working memory is influenced not only by cognitive control but also by the level of associated benefits. A goal with little or no benefit (neutral) will be weakly activated in working memory compared to conditions involving incentives (penalty avoidance, reward seeking, or the combination of both). It can be assumed that the combination of reward and penalty leads to stronger goal activation than penalty alone, potentially explaining the higher number of no-go errors observed in the penalty-only condition.

Spatial attention and working memory are popularly thought to be tightly coupled. Yet, distinct neural activity tracks attentional breadth and WM load. In a new paper @jocn.bsky.social, we show that pupil size independently tracks breadth and load. doi.org/10.1162/JOCN...

1/ Why are we so easily distracted? 🧠 In our new EEG preprint w/ Henry Jones, @monicarosenb.bsky.social and @edvogel.bsky.social we show that distractibility is associated w/ reduced neural connectivity — and can be predicted from EEG with ~80% accuracy using machine learning.
