Chick and Tilda, its mother (photo © and courtesy of Hannele Luhtasela-El Showk)It’s probably not a surprise that humans aren’t the only animals with a sense of numbers. While they’re probably not actually counting, a variety of species seem to be able to tell the number of objects in a group; they can distinguish between groups with greater or fewer objects and react with surprise when the number changes unexpectedly. However, a recent study suggests that this numerical understanding may go deeper than we’ve previously thought. Continue reading →

Instead of writing a post for Inspiring Science this week, I decided to share my first published feature article with you! It appeared in Issue 6 of Think magazine, which was published on Monday. I wrote about the research of Gordon Calleja, director of the Institute of Digital Games at the University of Malta, and also reviewed Will Love Tear Us Apart, a game he designed based on Joy Division’s song Love Will Tear Us Apart. You can read my feature below and also check out the other articles in the issue (it’s free!) and visit the magazine on Facebook!

Gordon Calleja has a dream job: he studies video games. It may sound like frivolous fun, but his work is serious research. He examines how people perceive the world around them and interact with it. His research blends aspects of philosophy, neuropsychology, and literary theory with futuristic concepts like cybernetics and post-humanism; his papers are peppered with references to Wittgenstein and Borges alongside quotes from avid gamers. In his book In-Game: From Immersion to Incorporation, published last year by MIT Press, Professor Calleja tackles the question of how we experience games – how the barrier created by the screen and the controls dissolves into a sense of really being there. ‘Ultimately,’ he says, ‘studying presence in games is asking how we are conscious here in the physical world.’

What lies behind illusions?

Old woman or young lady?Humans have an exquisite sense of vision. It’s the primary sense for most of us and our making way of interacting with the world around us.  We process the massive amount of visual data generated by sight using trillions of interconnections between billions of neurons spread across half our cerebral cortex.  Despite this, our visual system falls prey to illusions, constructing ambiguous interpretations and objects that can’t or don’t exist.  How do these illusions work and why do they succeed in fooling us even when we know about them?

How are humans like ants?

Last year, I wrote about how some ants can find their way home after finding food.  They have the remarkable ability to account for all the twists and turns they made while foraging and calculate a direct path leading straight back to their nest.  A reader emailed to ask if I thought humans would ever be able to do something similar or to achieve the level of co-ordination shown by ants.  This post is based on my reply, where I pointed out several things that humans are amazingly good at doing  — in fact, we do them so well and with such ease that you might be surprised by how difficult they actually are!  I’ve spent a lot of time on Inspiring Science talking about behaviours and abilities which show that other animals aren’t just simple automata because I think it’s important to make the point that although humans are unique, we aren’t special; we’re just another species with our own particular tricks for surviving in this world.  I’ll take a different tack in this post and talk about some of the ways we stand out!

Do ants really count their steps?

Formica rufa Several years ago, scientists published an excellent study about how desert ants find their way home after foraging.  The story got a lot of media attention; unfortunately,  much of the coverage described the ants “counting steps”, which isn’t what the researchers reported and feeds into existing myths rather than broadening our scope.  To explain what I think is wrong with that approach, I’m going to tell you a story about ants on stilts, body swapping and how we perceive space.

Social wasps are specialists at recognizing faces

A young female paper wasp (Image via Wikipedia)There’s lots of evidence that humans have a specialized mechanism for identifying and responding to faces; for example, people with a condition called prosopagnosia have difficulty recognizing faces but not other objects.  A few years ago, researchers showed that individual paper wasps of the species Polistes fuscatus recognize each other’s faces; the same team has now gone on to show that, like humans, P. fuscatus accomplishes this via a specialized mechanism for facial recognition rather than through general shape or pattern recognition.  This story is an excellent example of a  complex cognitive ability being exhibited by a creature with a relatively simple nervous system.
