“…The findings indicated mixed results with Lee (2002) and Nuevo (2006) reporting that no significant difference was found between manipulation of task complexity variables (+/-few elements and +/-no reasoning demands) and L2 development. However, a number of studies (Robinson, 2001b(Robinson, , 2005(Robinson, , 2007Iwashita et al, 2001;Gilabert, 2007;Kuiken et al, 2005;Ishikawa, 2006, Revesz, 2011 showed positive relationships between increasing complexity levels along the resource-directing dimension and increases in accuracy in L2 speech and/or writing. This would support Robinson's Cognition Hypothesis which posits that increasing the cognitive demands of L2 tasks lead to increases in the accuracy and complexity of L2 speech production (Robinson, 2001a(Robinson, , 2001b(Robinson, , 2005(Robinson, , 2007.…”
