Idea Sex and the Evolutionary Logic of Knowledge Transfer

Why do certain ideas succeed? Ideas have to pass a kind of Darwinian fitness test, argues the computer scientist Ramez Naam, who is the author of “More Than Human: Embracing the Promise of Biological Enhancement.” It turns out the most useful ideas are the ones that spread, like the wheel that was invented in Egypt and was improved upon in Sumaria by going from a solid disk to spokes. 

Passing the usefulness test crucially involves the ability of ideas to propagate themselves, just as biologically successful humans are able to pass on their genes. In the case of the wheel, two ideas met, and reproduced. In other words, the wheel was carried by humans to another place where it was then improved upon by other people. 

Your brain on video games

How do fast-paced video games affect the brain? Step into the lab with cognitive researcher Daphne Bavelier to hear surprising news about how video games, even action-packed shooter games, can help us learn, focus and, fascinatingly, multitask.

A Cognitive Model for Embodied Gesture Processing in Virtual Agents

Human social interaction encompasses verbal and nonverbal aspects in which hand gesture is a widely used nonverbal communication way. Handling gestures requires different cognitive and knowledge levels, from motor skills to social intentions behind those movements.

During social interaction all of these levels can be used for cognitive processes of both perception and generation, as evidenced by neuropsychological studies. In this video, motor skills of gestures at different levels of abstraction from movement trajectories towards higher levels of semantics is discussed. In this context, the aim to engage humanoid virtual agents in social interaction with humans.

To this end, the creators developed a cognitive computational model which tries to capture the embodied basis of hand gestures and we demonstrate how it enables to combine and bootstrap the online learning, perception, recognition and generation of gestural movements in a human-agent interaction scenario.

Matthew Goodwin PhD reveals several innovative technologies being developed to enhance and accelerate research and learning in individuals with autism spectrum disorders. During this talk, Goodwin also discusses applications of these technologies and what it means for families affected by autism.

KiDA (Kids Institute for Development & Advancement) is Orange County’s premiere center for autism, encompassing education, medicine, therapy, and research for children with autism. Learn more at kida.com or follow them on facebook (facebook.com/KiDA.autism) or Twitter (@KiDAcares4kids).

In a recent conversation, the question came up “How do the blind see or experience color?” This fascinating look at Superflux and neuroscientist Dr. Patrick Degenarrs collaborative project shows one possibile answer.

“What if we could change our view of the world with the flick of a switch? ‘Song of the Machine’ explores the possibilities of a new, modified – even enhanced – vision, where users can tune into streams of information and electromagnetic vistas currently outside of human vision.”

Why Angry Birds is so successful and popular: a cognitive teardown of the user experience - Charles Mauro.

It is a well-known fact of cognitive science that human short-term memory (SM), when compared to other attributes of our memory systems, is exceedingly limited. This fact has been the focus of thousands of studies over the last 50 years. Scientists have poked and prodded this aspect of human cognition to determine exactly how SM operates and what impacts SM effectiveness. As we go about our daily lives, short-term memory makes it possible for you to engage with all manner of technology and the environment in general.

SM is a temporary memory that allows us to remember a very limited number of discrete items, behaviors, or patterns for a short period of time. SM makes it possible for you to operate without constant referral to long-term memory, a much more complex and time-consuming process. This is critical because SM is fast and easily configured, which allows one to adapt instantly to situations that might otherwise be fatal if one were required to access long-term memory. In computer-speak, human short-term memory is also highly volatile. This means it can be erased instantly, or more importantly, it can be overwritten by other information coming into the human perceptual system.

Where things get interesting is the point where poor user interface design impacts the demand placed on SM. For example, a user interface design solution that requires the user to view information on one screen, store it in short-term memory, and then reenter that same information in a data field on another screen seems like a trivial task. Research shows that it is difficult to do accurately, especially if some other form of stimulus flows between the memorization of the data from the first screen and before the user enters the data in the second.

This disruptive data flow can be in almost any form, but as a general rule, anything that is engaging, such as conversation, noise, motion, or worst of all, a combination of all three, is likely to totally erase SM. When you encounter this type of data flow before you complete transfer of data using short-term memory, chances are very good that when you go back to retrieve important information from short-term memory, it is gone!

One would logically assume that any aspect of user interface design that taxes short-term memory is a really bad idea. As was the case with response time, a more refined view leads to surprising insights into how one can use the degradation of short-term memory to actually improve game play engagement. Angry Birds is a surprisingly smart manager of the player’s short-term memory.

By simple manipulation of the user interface, Angry Birds designers created significant short-term memory loss, which in turn increases game play complexity but in a way that is not perceived by the player as negative and adds to the addictive nature of the game itself. The subtle, yet powerful concept employed in Angry Birds is to bend short-term memory but not to actually break it. If you do break SM, make sure you give the user a very simple, fast way to accurately reload.

IBM - SyNAPSE: a cognitive computing project from IBM Research

Beyond machines

For more than half a century, computers have been little better than  calculators with storage structures and programmable memory, a model  that scientists have continually aimed to improve.

Comparatively, the human brain—the world’s most sophisticated  computer—can perform complex tasks rapidly and accurately using the same  amount of energy as a 20 watt light bulb in a space equivalent to a 2  liter soda bottle.

Cognitive computing: thought for the future

Making sense of real-time input flowing in at a dizzying rate is a  Herculean task for today’s computers, but would be natural for a  brain-inspired system. Using advanced algorithms and silicon circuitry,  cognitive computers learn through experiences, find correlations, create  hypotheses, and remember—and learn from—the outcomes.

For example, a cognitive computing system monitoring the world’s  water supply could contain a network of sensors and actuators that  constantly record and report metrics such as temperature, pressure, wave  height, acoustics and ocean tide, and issue tsunami warnings based on  its decision making.
