Condition Modifiers Sample Clauses

Condition Modifiers. These are not conditions by themselves, but allow you to modify how basic conditions work, or combine them into more complex conditions. until condition Evaluates to true until the first time condition evaluates to true. when condition Evaluates to true the first time condition evaluates to true. Equivalent to just condition; it is included to make scripts more readable. Note that it can only evaluate to true once per trial. after condition Evaluates to false until the first time condition evaluates to false. whenever condition Evaluates to true whenever condition is true. This dif- fers from when in that it can evaluate to true more than once in a single trial. not condition Evaluates to true if condition evaluates to false, and vice versa. both condition1 and condition2 Evaluates to true if both condition1 and condition2 evaluate to true. either condition1 or condition2 Evaluates to true if either condition1 or condition2 evaluate to true.
