“…Planning time has been considered as a processing condition whose role, especially in terms of language fluency and complexity in language production, cannot be ignored. By providing planning time in performing different task types, favorable results have been gained so far (Abdi Tabari, 2016;Amadian, 2012;Ellis & Yuan, 2004;Li, Chen, & Sun, 2014;Sangarun, 2005;Tavakoli & Skehan, 2005;Wang, 2008;Yuan & Ellis, 2003). Studies with different lengths of planning time have also been conducted, such as 15 minutes (Sangarun, 2005), 10 minutes (Gilabert, 2007;Yuan & Ellis, 2003), 5 minutes (Tavakoli & Skehan, 2005), 3 minutes (Williams, 1992), and 1 minute (Mehnert, 1998).…”
