Rhesus monkeys reason about perspectives of others in obtaining food

15.03.2005


Rhesus monkeys consider whether someone can or cannot see them when trying to steal food, indicating they have the ability to reason about the mental states of others, according to a study published this month in Current Biology.



In each of six experiments, two people stood in front of a platform, each with a grape attached to the platform. The experiments created competitive conditions, the monkeys were competing with the humans for the grapes.

The 115 monkeys tested only took the grape when they could tell that a person was not looking at them. The experiments varied from one person looking at the monkey and the other with their back turned, to one person having their eyes covered with cardboard and the other with only their mouth covered with cardboard.


"What we are interested in is whether monkeys can reason about the mental states of others," said Jonathan Flombaum, a graduate student in Yale’s Department of Psychology and the first author of the study. "Seeing is the most elementary piece of this. The simplest mental state is perception, what you see."

The experiments were conducted with semi-free-ranging rhesus monkeys on the island of Cayo Santiago in Puerto Rico.

Flombaum said the research could help shed light on the causes of autism. "There are many studies showing that autistic children don’t look at the eyes of others in the ways that other individuals do in the course of social interactions, and also that autistic children don’t use eye gaze information to make social and mental judgments about others," he said.

The senior author was Laurie Santos, an assistant professor at Yale. The research was supported by a National Science Foundation graduate research fellowship and the Yale University Moore Fund grant.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
