This study tests the theoretical predictions regarding effects of increasing task complexity (Robinson, 2001a, 2001b, 2007, 2010; Robinson & Gilabert, 2007) for second language (L2) pronunciation. Specifically, we examine whether more complex tasks (a) lead to greater incidence of pronunciation-focused language-related episodes (LREs) and (b) positively impact accuracy of phonetic form during task completion. Seventeen dyads of intermediate L2 Spanish learners completed simple (+few elements) and complex (-few elements) information-gap map tasks in which the pronunciation of Spanish vowels was made task essential through the inclusion of minimal pair street names (e.g., "Calle Copa" "Copa Street" and "Calle Capa" "Capa Street"). Results revealed no statistical difference in learner-produced pronunciation-related LREs in the simple and complex tasks. Vowel production, however, moved in a targetlike direction for one of five segments (/e/) during the complex task. Results therefore point to some benefits of task complexity manipulations for L2 pronunciation.
