Generating the angular velocities of planetary and annular gears: When self-generating explanations helps learning Tell me, how does a differential work? Can you explain it to me? All of us who drive or ride in cars rely on a differential to get us around corners under power, and yet not all of us know that […]
When more information leads to greater willingness to sacrifice: moral dilemmas and utilitarian accessibility Can it be moral to kill? Can we sacrifice a life to save many others? Or is killing always wrong? This fundamental question looms large in the philosophy of ethics. On the one hand, deontologists such as Immanuel Kant, argue that the morality […]
As a lecturer, I know my students but I do find it hard to keep track of which students are doing which modules and who graduated one vs two years ago. Complex group living requires animals to know and keep track of various relations between themselves and others. These could be seen in the form […]
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 […]
We are all part of a culture: certain behaviors and practices are deeply ingrained in our society and, by implication, in all of us. For example, one strongly normative behavior in the United Kingdom is to queue politely for the bus or the checkout in the supermarket. (Apparently this norm is so strong that disproportionately […]
Video games have gotten a bad rap. When googling “do video games”, the first results Google suggests are “rot your brain”, “make you dumber”, and then finally “make you smarter.” As far as the last option is concerned, evidence seems to be accumulating that shows that gaming does enhance visual processing and cognitive control skills. […]
One of the essential goals of psychology is generalization: describing ways in which people are similar. Of course, human behaviour varies across situations, times, and individuals, and hence often defies generalization. Ignoring this variability and assuming that people are the same can lead to improper generalizations about human behaviour. In a new paper in the Psychonomic Bulletin […]
I sometimes use MTurk for running experiments. As an old-timer, there is something of a magical quality to MTurk. You post your study and only a few hours later you receive data from perhaps one thousand or so people. I can remember when we used to meet the people participating in our studies face-to-face, with […]
Data is everywhere. Political campaigns, sports teams, and even music streaming sites rely on the collection and analysis of data to win, or to attain customers, and to sell targeted advertisements. Journalists use data to report the news and the public interprets data in consuming that news. Becoming data literate is no longer just a requirement of the scientist or the […]
How are the meanings of words, events and objects represented and organized in the brain? When we think of a dog, what representation are we invoking? Is there such thing as an abstract dogness—the doggiest of all dogs—or do we merely remember one of many stored exemplars of dogs that we have encountered in our lives? (If […]
