TurkPrime.com offers many features for using MTurk through a web interface. You can exclude and include workers, email them, restart survey and more. You can also create an account with SurveyComet.com if you do not reside in the US to find workers for surveys that you want to run. You can limit the workers by demographic which I have found to be extremely ...

So this will ultimately depend on your view of the physical word. Here's what I believe to a simpler example. Take a physicist who's observing the behavior of certain particles, as in the double slit experiment. I'd venture to say most people presume physics to be free of this "first person perspective" and yet the outcome of the double slit experiment is ...

Both offer a pretty nice set of tools to run externally hosted surveys (like on Qualtrics and SurveyMonkey) and allow you to create follow up surveys, exclude previous workers, have specific demographic Panels and much more. A long survey can be broken into two parts. Launch part 1 and later ...

Based on your comments I interpret your question as: "(1) What is the definition of the signal-to-noise-ratio (SNR) and (2) how do I determine the SNR for event-related potential (ERP) amplitudes in an EEG signal?". (1) Signal-to-noise-ratio (SNR) is a term often encountered in electrophysiology (e.g. EEGs) and signal processing and can be loosely defined ...
