چکیده

Task complexity in L2 writing and its effect on syntactic complexity have been of much research interest in the field of second language acquisition. However, very few studies have attempted to explore the impact of task complexity on measures of syntactic complexity in learners’ performance in integrated writing tasks. Therefore, the present study purported to investigate the impact of task complexity, operationalized in terms of the number of chunks in the graph, on measures of syntactic complexity, namely complexity, accuracy, and fluency (CAF) and lexical complexity in a graph description task. To this end, 94 learners of English as a foreign language at college level were randomly assigned to two groups, receiving a simple task and a complex task. The simple task involved a few-chunk graph, while the complex task had a many-chunk graphical prompt. The participants of the two groups wrote an essay describing the graph in no more than 45 minutes. The results revealed that the complexity and fluency of the learners’ output were significantly affected by the increase in the cognitive complexity of the writing task. However, there was no significant impact of task complexity on the accuracy of the essays.
