Wired for Speech: Voice Interactions with People and Computers
Stanford / Engineering (Except Electrical)
August 7, 2008 presentation by Clifford Nass for the Stanford University Office of Science Outreach's Summer Science Lecture Series. In this lecture, Clifford Nass describes how the human brain and body are "wired" for speech: The sound of a voice, whether from a person or machine, causes us to respond as we respond to actual people and to behave as we could in any social situation. In addition, Nass will discuss the speech interactions b...more

Professor Paul Bloom welcomes students and presents the course as a comprehensive introduction to the study of the human mind. Course readings and requirements are discussed. The five main branches of psychology are presented: neuroscience, which is a study of the mind by looking at the brain; developmental, which focuses on how people grow and learn; cognitive, which refers to the computational approach to studying the mind; social, which...more

The visual system has developed to allow us to navigate in a complex and dangerous world in order to find food and to avoid danger. This survival system works by building a complex three-dimensional model based on two-dimensional data from the retina. This model is tested against "reality" and checked with information from other senses and updated if needed. The brain suppresses the complexity of this processing and we believe that visi...more

Hawkins is working on his third start-up. Besides starting Palm and Handspring, Hawkins also followed his passion for theoretical neuroscience, the study of how certain parts of the brain work from an information theory point of view. He started a non-profit research institute called the Redwood NeuroScience Institute. Through this experience, he learned that starting a non-profit is just like starting a business.

This lecture reviews selected topics previously covered in lectures 1 through 5. This includes: scaling arguments, dot products, cross products, one-dimensional kinematics, trajectories, and uniform circular motion. Professor Lewin concludes by presenting a brain teaser to the audience. Sliding his fingers underneath a yardstick, towards the center, something strange happens: the fingers seem to make turns moving, they alternating slidi...more

One of the most uniquely human abilities is the capacity for creating and understanding language. This lecture introduces students to the major topics within the study of language: phonology, morphology, syntax and recursion. This lecture also describes theories of language acquisition, arguments for the specialization of language, and the commonalities observed in different languages across cultures.

Professor Diamond continues her discussion of the nervous system with a diagram of a cross section of a developing spinal cord in which she highlights the ependyma, the mantle layer, the neuronal soma, and the marginal layer. She compares the developing cord to an adult cord and discusses the ventricles, the posterior and anterior horn, and the lateral horn in the thoracic cord. After relating these to the sympathetic division of the autom...more

Professor Brian Wandell tells the inspirational story of Mike May, the world-record holder for blind downhill skiing. Wandell leads a multidisciplinary team of Stanford researchers who are working together to treat the many dimensions of blindness: retinal imaging, neural connections, and social psychology.

How hormones, phermones and bonding chemicals connect with the experiences of sexual arousal and romantic love. To what extent are we victims of our brain chemistry and neural processes? What are the evolutionary origins and adaptive values of "falling in love"?

Just how near are we to using our brains routinely to control machines for work or leisure purposes? Will we be able to improve the performance of our existing brains? Have advances in neuroscience, neural network modelling and the physical sciences led us to the point where it could soon be possible to create artificial, nanoscale brains and where might such technology lead us?

Dr. Russell Fernald discusses how social behavior changes the brains of fish, animals, and humans to adapt to situations typically involving mating behaviors. The lecture is concluded with a panel discussion with Eric Knudsen and Charles Junkerman.
