Get high for free: stare in a friend's eyes for ten minutes


Induced dissociative states are the best dissociative states, and one cheap and easy way to get there is to stare into someone's eyes for about ten minutes. More researchers are looking into the phenomenon. Read the rest

WATCH: More DeepDream obsessions

Since Cory posted about the Deep Dream image recognition algorithm last month (and Rob earlier today) it's inspired an explosion of iterations like Roelof Pieters' DeepDreamed Fear & Loathing in Las Vegas. Read the rest

Hearing lips and seeing voices

This video explains the weirdness of the McGurk effect, a perceptual illusion demonstrating that understanding speech is not just about what we hear, but also what we see. You can learn more about the McGurk effect at Yale's Haskins Laboratories dedicated to the science of the spoken and written wordl. (via Imaginary Foundation) Read the rest

Whistling Speech

I really love the research that they're doing over at Yale's Haskins Laboratories: instead of studying speech perception and production in terms of faithfully replicating alllll of the sounds we make with our mouths, (like the minute clicks, pops, and hisses of consonants), the team is proposing that all we need to understand speech is to track and re-create a few select resonances of the vocal tract. I like to think of speech production in this context as a series of bottles with varying levels of water in them--the mouth is one bottle that changes pitch resonance when you move it to open it or close it, the nasal cavity another, and so on throughout the vocal tract. It ends up sounding like a bunch of complicated melodies that are then combined into a complex micro-tonal harmony, a.k.a., we're all better at perceiving and making music than we think we are!

The examples below break it down into isolated sine-wave patterns that you can combine yourself to build a sentence. What do you think? How easily can you hear words emerge?

Tone combinations

Play Tone 1 alone | Play Tone 2 alone | Play Tone 3 alone | Play Tones 1 and 2 together

Play Tones 1 and 3 together | Play Tones 2 and 3 together
