Wanting ahead -- Birds plan for future desires

27.04.2007
For a long time, it had been argued that only humans can draw on past experiences to plan for the future, whereas animals were considered “stuck in time.” However, it has become clear that some animals can indeed plan for future needs. Surprisingly, the most convincing examples of future planning are not derived from our closest relatives, the apes, but from a bird, the Western scrub-jay.

The Western scrub-jay is native to the western United States, and, like squirrels and other food-caching animals, these birds readily store food for the future and recover their caches at a later date. It was already known that the jays can plan ahead and store food in places where they have learned they will be hungry the next morning and where they know the type of food will not be available. But a key issue had remained unresolved—namely, whether the birds can plan ahead in response to a motivation or desire they do not experience in the present. In other words: Can the birds know what they are going to want in the future?

In new research, appearing online on April 26th in the journal Current Biology, published by Cell Press, Sergio Correia, Tony Dickinson, and Nicky Clayton of the University of Cambridge, UK, used a phenomenon called “specific satiety” to address this issue. Like many other animals, when sated of one type of food, Western scrub-jays prefer to eat and store another type of food. Correia and colleagues used this effect to ask whether the birds prefer to store the food they want now or the food they think they will want when they come to recover their caches in the future. At the start of the experiment, the birds stored the food they desired at the time, but the birds switched to storing the food that was valuable at the time of recovery rather than the one they wanted to eat at the time of caching.

These experiments provide the first-ever evidence that animals can plan future actions not only on the basis of what they currently desire, but also on the basis of what they anticipate they will desire in the future. This is another striking example of how animals show features of intelligence that were once thought to be uniquely human.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
