We owe most of our visual acuity to the fovea, the central area of the retina that is most densely packed with receptors—around 150,000 cones per square millimetre. Whenever we focus on an object, we move our eyes so ensure that the image is projected onto the fovea. And we see whatever is there, irrespective of […]

Put Tom Cruise and Dustin Hoffman together and you get Rain Man, the Academy-Award winning story of an autistic savant—played by Hoffman who received the Best Actor award for his performance—who turns out to have many unexpected talents. The clip below shows one famous scene, in which Hoffman knows within seconds that the waitress dropped […]
“They began three and a half centuries ago,” writes Gernsbacher (2018, p. 403). They can delight us or frighten us, teach us and confuse us, intimidate us or encourage us. They are the base unit of productivity and the currency of academic prestige and advancement. “They,” of course, are scientific journal articles. The professional academic […]
Humans have a sort Dr. Jekyll/Mr. Hyde relationship with safety devices, such as helmets. For example, on the one hand bicycle helmets are known to reduce serious head injuries (by 70%, it turns out). On the other hand, helmets might also lead to more risky behavior. For instance, cyclists are often thought to ride faster […]
All around us during the Christmas season are images of God taking human form. A divine baby boy conceived by the Holy Spirit and a virgin mother, born in a stable in Bethlehem two millennia ago. A boy who grows into a man, who teaches widely, who is brutally killed. In most Christian traditions, God […]
Recently, an error was found in this paper. The updated paper is here. —– Do you like talking on the phone to strangers? No? Well, neither do I. And for good reason – talking to someone you do not know over noisy speakers that lose part of the sound spectrum can be challenging, especially if […]
Apparently the internet, video games, and social media are damaging our children’s development, and are responsible for the increase in autism over the last few decades—or so it has been claimed, although that claim hasn’t withstood scrutiny. Similarly, Wikipedia has an entry for something known as Internet addiction disorder, which apparently occurs when internet use […]
People are capable of inferring many attributes of an object by wielding it. Pick up a hammer and you can get a fairly good idea of its length, width, and shape (an ability that is known as exteroception). You will also acquire information about the orientation of the hammer in your hand (exproprioception), and your […]
Remember answering machines? Me neither, but this is why Seinfeld exists. When Jerry’s girlfriend, Sophie, leaves a message without stating her name (just, “it’s me!”), Jerry decides to call her back without stating his own name. Stripped of visual and contextual cues—Jerry’s face, what he’s wearing, his name—Sophie fails to identify him by just his […]
There are no new ideas in Hollywood. The top 12 grossing films in the US last year were all, in one way or another, derivative content (6 super hero films, 3 remakes, 2 sequels, and a Star Wars). The increasingly serialized nature of the film industry may derive from the rise in recent years of […]
