Good music

So, staying with the theme of creativity, let's explore the domain of music -- something we all are familiar with. What makes good music? Is it being new and creative? Do we habituate easily to music and thus demand something unique?

What are some examples of musicians that are hugely successful? Is creativity necessary for success over both the short-run (a year or two) and/or the long run (decades)? Though I don't own any of his music, one example is Elton John who has managed to crank out hits consistently over the past 30 years. Is he creative? If not, then who is? Can you be successful without writing your own music?

Bot Homework

Software developers are rapidly trying to mimic and develop artificial forms of intelligence that appear similar to human forms. The benchmark for success in these endeavors is the Turing Test. This is a simple test where you ask a machine and a human similar questions. If you can’t tell the difference between the computer’s response and the human’s, the Creator of the machine is said to have achieved artificial intelligence.

There are a lot of recent attempts at this on the web that you can check out. These “machines” are called “chatterbots”, or just “bots”. Go here http://web.infoave.net/~kbcowart/. To talk with a bot: first click on one of the names on the left (blue hotlinks), that takes you to a summary page of the bot -- click on the "website" link at the top to get to the actual bot page. You should then find a link to start talking. Alice is always a good one to start with. Have some conversations with a few of them. Find your favorites and answer the following questions. Give rationales for each answer. Make sure and finish this by Wed. night.

What Q&A exchange was most humanlike?

What Q&A exchange revealed the inadequacies (in human terms) of the bot?

What was the most interesting exchange?

Would these bots pass the Touring Test?

Post your answers here on the blog.

Sex differences in spatial ability?

It is often said that men have the edge over women in spatial ability. Actually, this is true only for some spatial abilities, such as mental rotation. Women, on the other hand, are superior to men on other spatial tasks such as object location.

The explanation for men's advantage in mental rotation is that way back in our evolutionary history, men were hunters and had to travel great distances to hunt and find there way back. But if this wayfinding is the reason behind the ability, how come much dumber animals like birds and salmon can travel thousands of miles (much farther than men's hunting ranges) and find their way back. It follows that any human (male or female) could possess this wayfinding ability given the size of our brains. In fact, "bird brain" is a disparaging comment. Something isn't adding up here. Any thoughts?
