New Paper! w. Léa Entzmann and Árni Kristjánsson TL;DR: Endpoint deviations are determined by current target-previous distractor difference, but do not reflect the shape of the previous distractor distribution. Saccadic latencies do reflect these distributions. jov.arvojournals.org/Article.aspx...

What does our conscious perception of this set of berries consist of? If you heard about Ensemble perception, you could say: “It’s too much info for our poor attention/working memory systems, so instead of storing all the individual features, people just represent the average and variability.” 1/5

ENDILEGA DEILA Viltu taka þátt í rannsókn? Þráður 🧵 Upplifir þú liti þegar þú horfir á bókstafi? Ef þú ert eins og manneskjan til hægri þá upplifir þú fyrirbæri sem nefnist samskynjun. Til að geta rannsakað fyrirbærið þurfum við gögn frá fólki MEÐ og ÁN samskynjunar. 1/5

New IVL paper by Léa Entzmann et al. Feature distribution learning measured by manual and saccadic responses. Spoiler: Results essentially the same across response modalities suggesting attentional orienting - not decisional - effects of FDL. Mandatory shoutout to @achetverikov.bsky.social

How does color distribution learning affect goal-directed visuomotor behavior?

While the visual world is rich and complex, importantly, it nevertheless contains many statistical regularities. For example, environmental feature di…
