Rather the experimenters ground up food pellets and then recompacted them to make them softer.
This pool is then expanded by the experimenters and redistributed to individuals in the group.
That was, in part, because experimenters were often amateurs who were spending private money.
Neither the volunteers nor the experimenters could say reliably which drug was being administered on which occasion.
This simple finding has huge implications for tests in which chimpanzees need to pay attention to human experimenters.
First, he says, the experimenters basically ground up whole bees, when dissecting them first might have yielded more information.
Or is it, in fact, the pet approach of the experimenters pitted against a treatment-as-usual or less than ideal opponent?
Nest also reports that in its Rush Hour Rewards test of 2, 000 Houstonians, only one-tenth of the experimenters felt too warm.
In one study, experimenters measured the facial width-to-height ratio of 192 Masters of Business Administration students, 115 of whom were men.
The emotions that the experimenters tested were communicated solely by chemical signaling.
Experimenters found a correlation coefficient of 0.46, after accounting for age differences.
Meanwhile Google Earth, though it works just fine with a regular mouse and keyboard, cries out for experimenters to devise cooler navigation techniques.
Dr Heinrich and Dr Bugnyar found that all the birds were able to follow the gaze of the experimenters, even beyond the barrier.

Very few managers in organizations see themselves as innovators or experimenters.
More cynical experimenters say that the golden age of theory is over, now that the days of freewheeling mathematical carousing are drawing to a close.
The experimenters discovered that adding additional laser beams to fire at the quantum fluid, they could create ever more complicated quantum states, right before their eyes.
But the critics point out that the inventions that have done most to change the world often come from solitary experimenters, corporate renegades and other oddballs.
Experimenters at the Phoronix forums have found that Chrome 21 has support for the Stage 3D hardware acceleration needed to drive Epic Games' Flash conversion of UE3.

Even if experimenters bounce the beams to and fro to increase the effective length of an interferometer's arms to more than 100 kilometres, the expected difference in length between the two beams' paths still amounts to less than a hundred-millionth of the diameter of a hydrogen atom.
