This dissertation studied developmental differences in the way simultaneous and sequential signal to noise ratios impact contextual cueing effects. Contextual cueing refers to a form of implicit associative learning of the target location and its context. Over repeated exposures, participants typically respond faster to repeated displays than to new displays that are not repeated. Previous stud...
the record of human brain neural activities, namely electroencephalogram (eeg), is generally known as a non-stationary and nonlinear signal. in many applications, it is useful to divide the eegs into segments within which the signals can be considered stationary. combination of empirical mode decomposition (emd) and hilbert transform, called hilbert-huang transform (hht), is a new and powerful ...
Signal-to-noise ratio, the ratio between signal and noise, is a quantity that has been well established for MRI data but is still subject of ongoing debate and confusion when it comes to fMRI data. fMRI data are characterised by small activation fluctuations in a background of noise. Depending on how the signal of interest and the noise are identified, signal-to-noise ratio for fMRI data is rep...
