-
Design and Interpretation of ERP Experiments
-
Examples of Experimental Design
- Basic science example (Attentional Blink); translational example (P3 and LRP in schizophrenia)
-
ERP Localization
- The forward and inverse problems, equivalent current dipole approaches, distributed source approaches, MEG, hypothesis-testing approach and example
-
Time-Domain Signals, Filtering, and the Overlap Problem
- Fourier analysis, filtering in the frequency domain, filtering in the time domain, convolution and the relationship between the time and frequency domains, examples of filter distortion, overlap as a convolution
-
Plotting, Measurement, & Statistics
- Plotting, measuring amplitudes and latencies, choosing measurement windows, the jackknife approach, basic statistical approaches, electrode interactions and normalization, heterogeneity of covariance and the epsilon adjustment
-
General Principles of Time-Frequency Analysis
- Conceptualization of time-frequency analysis as a type of filtering, critical analysis of the ability of time-frequency analyses to obtain evidence concerning bona fide oscillations
-
Setting Up and Running an ERP Lab
- Recording chambers, seating, response devices, hints for running subjects, ethical issues, stimulus presentation, writing an ERP paper
