Foraging for… insects?!

People generally avoid disgusting things, but what if you’re deciding whether to eat them? At an experimental buffet, people spent more time looking at edible insects and other unusual snacks. However, they only rated the insects as more disgusting. This suggests that novelty drives looking behaviour when we’re foraging, and can even overrule the tendency to look away from disgust elicitors.

Tom speaks at the 1st Dutch Pupillometry Symposium

Thomas Hawkins presenting at the Dutch Pupillometry Symposium

Tom Hawkins gave a talk at the 1st Dutch Pupillometry Symposium. He presented a computational model of pseudo-neglect as an attentional gradient over the horizontal plane that fades out over time. It managed to capture individual differences in spatial bias, and when and how fast participants’ alertness faded during a task.

Testing children with iPad games

Testing children is less easy than testing adults, primarily because they lack the social inhibition to tell psychological researchers to go away with their super boring tests. This presents a problem in developmental research: How do you reach these kids?! We developed a bunch of iPad games to test the cognition of an entire classroom in one go. And it works!

Computer vision: Taylor Swift saliency mapping

In cognitive neuroscience, we’re interested in what guides human attention. We distinguish between influences from high-level cognition (e.g. current goals), and low-level visual features. There are highly sophisticated models of how visual features such as intensity, colour, and movement guide human attention. Computerised implementations of these models allow computers to mimic human eye movements. Turns out Taylor Swift’s amazing videos are an excellent example!
