From duck herding to pillow fighting: Making sense of observed action

If you’re like me, you’ve been busy trying out new hobbies in the last couple of years. Maybe you’ve taken up gardening, sculpting, hiking, or knitting. Or perhaps you’ve taken up a more unusual one: competitive duck herding, extreme ironing, ostrich racing, or worm charming. (Yes, these are all real activities!). But before you run […]

AP&P Digital Event: FIT week is over. What is next?

In my post to begin FIT week, I gave my account of the beginnings of my interest in Anne Treisman’s work and in her Feature Integration Theory (FIT). She had hypotheses about the relationship between preattentive features and early cortical processing that I wanted to challenge. As part of that project, since I had not […]

AP&P Digital Event: Pop-out effects in visual search: Humans vs Archerfish

All animals need to search their environment – for food, for predators, for mates. When humans search for a specific target, the target often pops out from the background. For example, in the image below, the fish is obviously different than the people. No matter how many people were present, the fish would always be […]

AP&P Digital Event: Visual perception and bubble graphs

Whether it be in media reports, articles, or apps on our phones, we encounter graphical depictions of critical information. Since the beginning of the COVID-19 pandemic, media outlets have relied on various graphical depictions to convey critical information. Consider the graph below from the NY Times showing the change in spending between 2019 and 2020, […]

AP&P Digital Event: It all comes down to objects

It all comes down to objects. How does the visual system manage to establish and maintain representations of objects in the world, despite almost constant change in input with shifts of the head and eyes, change in the urgency of different goals, and change in the objects themselves? It’s crazy, really, that it can be […]

AP&P Digital Event: How stable is the representation of an object during a visual ‘snapshot’?

Imagine I flash you an image of an animal in a savannah scene, say an elephant. You briefly view the image, and then you are asked to report its content while referring to specific details such as the type of animal and its position in the scene (e.g., was it facing the right or the […]

AP&P Digital Event: Looking for a new preattentive feature

Anne Treisman’s most important contribution to science is her feature integration theory of visual attention, which is arguably one of the most important works in the history of cognitive psychology and visual science. In brief, this theory proposed a two-level model. Preattentive features are extracted in parallel in the early visual system so that the […]

AP&P Digital Event: Preattentive processing is attentive processing with distributed foci

I once asked Anne Treisman, my Ph.D. supervisor, how and when I could get my Ph.D. Anne told me that I will get it once I learn all the good things from her and establish something of my own. This meant that I must learn everything about focused attention then find something new. Considering the […]

AP&P Digital Event: Historical academic context gives key insights for graduate students

One needs to look no further than the rich set of articles in this special issue to know that Feature Integration Theory (FIT) continues to be one of the most influential sets of ideas in cognitive psychology. From research on multi-sensory integration to depression, the seeds of Anne Treisman’s theory have spread far and wide. […]

AP&P Digital Event: Welcome to FIT week

My decades-long involvement with Anne Treisman’s Feature Integration Theory (FIT) must have begun in 1986. I was a junior faculty member at MIT at the time, working on visual aftereffects and binocular vision. I didn’t know much about attention. One might say that I had not paid attention to attention. Then, in 1986, Anne published an […]
