Maybe I’m a Luddite, but I was shocked to learn that my car can read me my text messages, switch to a song I want to hear, or navigate to my apartment. This is the natural progression of things—voice-based media systems in modern cars are becoming more and more common, especially in cars purchased by […]
Attention
What color is Wednesday? If the answer is obvious to you, you might have a form of synesthesia in which sequences such as numbers, days of the week, and months of the year are perceived as having colors (or else you might be from Thailand). Initially, one may well be skeptical on being told that […]
Imagine your daily commute. Think about 2+2. Don’t picture pink elephants. These examples illustrate the automaticity of cognition. On highly familiar routes, people habitually and automatically navigate, sometimes taking a familiar route absent-mindedly even when they needed to run an errand some place else. I’d be willing to bet that most people reading this couldn’t […]
Better get those headphones: We can’t really ignore task-related noise Like many people, I work in an open office. Workers increasingly find themselves in open offices as companies (and universities) switch to these layouts in a bid to maximize space and reduce building costs. In my case, I work remotely but share a local co-working […]
One of the most hair-raising thought experiments in philosophy of mind is the philosophical zombie, a being that is physically and behaviorally identical to a normal human, but is not conscious of having any mental states, like the fellow on the right in the figure below. The existence of such a being provides […]
Steve Yantis was a leading researcher in attention and cognitive neuroscience who passed away two years ago. In recognition of his work for the Psychonomic Society, one of the Society’s Early Career Awards is named in his honor. And just this week, a special issue of the Psychonomic Society’s journal Attention, Perception, & Psychophysics appeared in honor of the contributions […]
The waiter asks whether you’d prefer potatoes or rice with your entrecote. Are you free to make that decision based on, well, free will? Or should you respond with “Look, I am a determinist. I will just wait and see what I order because I know that my order is determined”? At first glance, the […]
Attention guides human perception, memory, and action in intriguing ways. Some time ago on this blog we learned that visual search can be directed by conceptual information: Saying or reading a word such as “tomato” makes it easier to find red things. We also learned on this blog that looking at a tomato can help you touch […]
Have you stood in line at the Louvre in Paris to catch a glimpse of famous Mona Lisa’s smile? People say that besides her ambiguous smile, her gaze tends to follow you, which might add to the mysterious aura that has been created around her for centuries. There is a considerable body of evidence that […]
We owe most of our visual acuity to our fovea, the area of the retina that is most densely packed with photo-receptive cones. Whenever we focus on an object, we move our eyes so that the image is projected onto this area that contains nearly 150,000 cone receptors per square millimeter. Anything that is projected onto […]
