Two examples with commentary EXPE's syntax Expe's syntax is deliberately minimalist. Typically, command lines are executed sequentially, one after another, in the order in which they are encountered. Expe also has variables which can be manipulated just as easily as constants. Again, variables have no particular type and can be used as arguments of functions requiring strings or numbers.
Variables are especially useful for counting subjects' good and bad responses.
Several of our experiments involve adaptative training where the training block ends when a certain performance criterion has been reached.
