Learning and Memory

When hand waving turn pistons into engines: The role of gestures in creating understanding

Conversations in Milan, Rome, or Madrid seem ever so much more animated and exciting than those polite chats over a tea cozy in Oxford, London, or Wetwang (Yorkshire). At least in part, this may reflect the greater physical rigor that denizens of the Mediterranean exhibit during their speech. As the New York Times put it: […]

Why does your tummy hurt: The place or the food?

When we were first married, my husband and I frequented a local BBQ restaurant. He ordered the fried chicken – all drumsticks – and I loved the brisket sandwich.

Is iron stronger than copper? When data and theories tell different stories about forgetting

We forget. Whether we trade the name of a fish for the name of a student, or whether we eventually forget the name of the U.S. President, the loss of information from memory is nearly always unavoidable. The reasons that underlie forgetting are, however, still debated. One putative mechanism that has attracted considerable attention is the idea […]

Simian memory has no time for decay

A variety of things can influence memory, and we frequently find that existing knowledge can impact the learning of new information. For example, some people (including me) find it hard to learn to drive an automatic car because of their pre-existing knowledge of driving a stick shift (standard) car. For example, early during the transition, […]

Keeping your mind on the cycle ball: Region of proximal learning and mind wandering
