Attending to Moving Objects is my book on multiple object tracking, published by Cambridge University Press but formatted as free webpages here.
The publisher’s word limit was too low to fit my advanced material about attending to moving objects, in particular its temporal limits.
From Attention to Distraction is a free textbook I use to teach about attention.
Short intro to presbycusis (age-related hearing loss) for psychology undergraduates
I also do meta-scientific work, e.g. with the Contributorship Collaboration I co-lead.
