48 It is also possible that recall bias could have contaminated the responses.
But he contaminated our response (and his gratification, if he gets my message) by slamming in totally irrelevant Fs, so that the noise we made was both genuine laughter and counterfeit laughter.
Finally, illusory responses in the Pareidolia test may not purely reflect visual illusions and may be contaminated by confabulatory responses.
In addition, responses to the catch trials were discarded from the data analysis to ensure that the MEG signal was minimally contaminated by motor responses.
These response trials were subsequently discarded from the data analysis to ensure that the MEG signal was not contaminated by motor responses.
To represent noise each Gaussian sensor response was multiplied by 100 random numbers with mean value of 1 and a standard deviation of 1% to represent 100 nominally identical responses contaminated with 40-dB noise.
In normal behavioral situations, animals have only limited time to distinguish meaningful stimuli on the basis of neuronal responses contaminated with noise.
However, to examine whether the order of sessions contaminated the brain responses, we also conducted a control experiment that was the same as the main experiment, except that the order of sessions was reversed.
Even in primitive cell contaminated cultures significant responses to PHA could be measured if conditions were modified to prevent increasing acidity.
Pro-cues were necessarily closer in time to the previous response than retro-cues, and the pre-stimulus baseline was therefore more likely to be contaminated by any response artifacts, such as eye blinks that accompany responses, than it would be for retro-cues.
Citation counts are attractive raw data for the evaluation of research output: they are "unobtrusive measures that do not require the cooperation of a respondent and do not themselves contaminate the response (i.e., they are non-reactive)" [21, p. 84].
