Schematic of a language paradigm. First row, Schematic illustration of a semantic run (duration, 140 seconds [s]). Syntactic runs comprised syntactic tasks instead of semantic tasks. Second row, Construction of pseudorandomized control periods (duration, 20s) and the first sentence of the semantic task 2 (duration: 20s) shown in detail. Every task comprises 2 sentences. Third row, Comparison of the construction of a semantic and a syntactic error sentence (as appearing in semantic/syntactic runs). Note that due to the translation into English, the verbs are no longer at the end of the sentences. The original German sentences read “Er wird den Löwen fahren/zähmen” (semantic error) and “Ich werde die Schrauben befestigt/befestigen” (syntactic error).
