q3 · i? · causal · r1

The experiment's design crossed "the presence or absence of explicit instruction" with the variables complexity and morphology/syntax across "four L2 structures" in an artificial language. This describes the study's factorial scope as the article states it.

"This study investigates the interaction between the presence or absence of explicit instruction and thevariables complexity and morphology/syntax in the acquisition of four L2 structures."

• No differential effect of explicit instruction depending on the variable morphology/syntax — related
• No differential effect of explicit instruction depending on the variable complexity — related
• Learners' grammar noticing centers more on syntax than morphology, with syntax issues encountered by all participants — related
• Explicit L2 grammar instruction leads to larger learning effects than implicit instruction, as reported in the reviewed synthesis literature — a broader claim this one bears on
