Chapter 4 -- Stimulus Events
Showplay real-time paradigms are designed to execute a sequence of stimulus events. These events are listed in a Stimulus Table specified in a paradigm parameter file (PPF). In the stimulus table, the first column specifies the stimulus type (usually a character string) and the remaining columns specify the timing and other control arguments for that stimulus.
There are 3 categories of stimulus events: Stimulus Files, Text strings, Event Commands. The following list summarizes all 3 types (click a link for details):
