Target Confusability Competition Model
We have recently proposed a new way of conceiving of visual memory, combining psychophysical scaling of similarity with signal detection theory (see Schurgin, Wixted and Brady, 2020, Nature Human Behaviour; PDF). Both of these are extremely well-established concepts, but together they result in a simple model of both visual working memory and visual long-term memory that allows us to make novel predictions and explain memory performance in a very straightforward way. All models like this are best explained visually — and with animations. Even signal detection theory, which many people have some familiarity with, is a more profound model than many realize — signal detection theory is much more than just a "measurement model" for correcting for response bias. It's really an entire framework for conceiving of memory and decision making under noise. Thus, we've made this informal primer to help people understand the model we are proposing. If you'd rather see a short talk, you could also w
