The fEMG data were integrated in 50 ms intervals during the first 1000 ms after stimulus
The participants were informed about stimulus
equivalence and the purpose of the experiment as they exited the experimental setting.
Figure 2 shows the proportion of responses in the presence and absence of the stimulus
during the [t.
A single stimulus
was presented in one of the four positions for a maximum of 5 s.
a You can do that by decreasing distance to X minus Y; by increasing movement of the stimulus
at distance X (a child walking, skipping, or swinging her arms); by increasing number of stimuli (two or three children, instead of one); increasing the visual "threat" (a tall man instead of a short one, or a man with a beard instead of a clean-shaven one); or by increasing volume (if it's a stimulus
that makes noise, such as a vacuum cleaner).
In contrast, experimenters remove the selected stimulus
from subsequent trials during an MSWO procedure allowing the student to select from the remaining stimuli (DeLeon & Iwata, 1996).
When proposed, President Obama's stimulus
Senator Paxton opposed the stimulus
and still does.
These results thus seem to support the general relevance of the hypothesis that motivated the present study: perceptual learning is enhanced by preexposure conditions most favouring stimulus
We focused on the cortical response time-locked to the disk stimulus
We found that only 41 percent of the companies that received stimulus
grants or contracts actually hired workers for the relevant project.
Birds trained to choose the larger stimulus
required from 12 to 48 presentations to achieve the criterion; birds trained to select the smaller stimulus
-from 16 to 51 presentations.
