“…Objective task complexity comprises code complexity, such as syntactic and lexical demands constituted by the writing task, cognitive complexity, like the mental processing demanded by the task, including the availability of relevant knowledge, and communicative stress generated, for example, by the number of participants involved and criteria for correctness used to assess the performance (Candlin, 1987: p. 10). Similar distinctions can be found in other studies, such as Brindley (1987), Nunan (1993), Mangos and Steele-Johnson (2001), or Sanajoo and Asadi (2016), all indicating that task complexity, in general, can be determined by analyzing the task into features that supposedly generate difficulty.…”
