The serial search strategy requires the mouse to use the multiple relationships among extra-maze stimuli to find the escape tunnel (Barnes 1979; Bach et al. 1995).
NC crows did not learn to use these stimuli to find the hidden rewards over 20 trials, even though the searching tasks were given after the Aesop's Fable experiments, and all of them had already been associated with reward.
Mr. Perriss added for good measure another stimulus to be found abroad that he joked Americans might not know about: ads to promote a big European soccer tournament next year.
Further analysis on the behavioural patterns elicited by the presentation of biological motion stimuli would contribute to find a more valid measure of shoaling behaviour.
NCI did this, he says, by using much of its stimulus money for 4-year grants, paying for the first 2 years with stimulus funds and "pledging" to find money for the third and fourth years.
She told the Guardian: "If we don't do Doha (the current round of trade talks) you could see a spiralling economic downturn and countries trying to find stimulus packages for businesses and banks to support their own industry.
Finally in the Form Constancy test, children were shown a stimulus figure and asked to find it in a series of figures.
However, when we examined the responses of optogenetically identified PVs and SOMs to the oddball stimulus, we were surprised to find that both types of interneurons themselves exhibited SSA, which was not consistent with this prediction.
Adaptive features other than the one under test may need to be turned off during the measurement, because it is difficult or even impossible to find stimuli that keep all other subsystems in steady-state as a reaction to the stimuli.
