A New Reverspective

download

One of the very strange effects of reverse perspective is that the images seem to follow you as you pass by them. As if, while you are observing them, the pictures are watching you back. John Kubie of SUNY Downstate Medical Center realized that, in the case of the Hollow Mask illusion, this must have to do with how viewers track the perspective of the nose of the nose with respect to the rest of the face.

Grandfather_Clock_Face_Waters_building_EXPLORE_4-8-08_2828

“Too late” might be the two most tragic words in English, but what if you could rewind the clock? What if the past was not immutable? Would we regret past bad decisions more or less? Would it affect the way that we feel then about our past choices, and the moral decisions that we may face in the future? New research has found out using virtual reality.

How Brains Know Where Things Are—Making Space by Jennifer Groh

cover

Groh launches her book with a BIG FAT LIE: she tells us that nine-tenths of our brain power is spent determining where things are. Then she immediately admits that she just made that up, but that she’d dedicate the rest of the book to explaining why she thinks its true. I was hooked! Brilliant, tantalizing, probably correct, but maybe not! I knew right then I would read this book cover-to-cover.

Your Brain on Thanks

800px-Frances_Brundage_Thanksgiving

Thanksgiving is my favorite holiday. It may not have the cache of winter holidays or the Cash! Yay! of a birthday, but it is the best feel-good holiday of the year. At least it feels that way to me.

Watch for Pickpockets! (Ypsilon via Wikimedia Commons)

One consequence of my laboratory’s collaboration with stage pickpocket Apollo Robbins is that I am often asked for strategies to thwart pickpockets in the real world. My usual advice is to avoid multitasking while you’re out and about, especially in the midst of a crowd. I speak not only from my experience as a cognitive researcher, but also as a former victim of pickpocketing.
