The present study investigated the potential of writing in English as a foreign language (EFL) for language learning by manipulating cognitive task complexity based on related models and hypotheses. English essays written by 59 Chinese postgraduate EFL students from different subject areas were analysed with reference to writing complexity, accuracy, and fluency (CAF). Results showed that task complexity had no significant effect on EFL learners’ lexical complexity but had an influence on their syntactic variation in EFL writing. Findings suggest that manipulating writing task complexity could be a feasible means to promoting and enhancing EFL learners’ language learning. Such findings might broaden our understanding of the relationship between EFL writing and language learning in an EFL learning context. The interplay of EFL writing and EFL learning is also pedagogically relevant to those who are interested in appropriately sequencing tasks for more effective language teaching.

Control Study

Background: Patients with cervical dystonia (CD) show impaired postural control, balance, and gait, likely due to abnormal head postures and sensorimotor disturbances. However, until now no study has investigated whether attention-demanding activity worsens postural control and balance in CD patients.Objective: To investigate whether patients with CD show cognitive-motor interference (CMI), a specific kind of dual-task interference that occurs during the simultaneous execution of a cognitive and motor task. This information may be useful to determine whether performing activities of daily living worsens postural control and balance in CD patients.Methods: We performed a pilot case-control study. Twenty-two patients affected by CD and 19 healthy controls were enrolled in order to test CMI. Each subject was evaluated during the execution of a cognitive task while postural stability was assessed through a stabilometric platform.Results: CD patients showed impaired postural control compared to healthy controls, with instability increasing with increasing cognitive task complexity. No relationships were found between stabilometric parameters and clinical characteristics of CD.Conclusions: Our hypothesis is that CMI in CD patients derives from deranged network connectivity when activated simultaneously during the performance of two tasks that interfere with each other and “compete” for the same resources within the cognitive system.

The Relationship

According to Robinson's Cognition Hypothesis of task-based L2 development, cognitively more demanding tasks will lead to the use of lexically and syntactically more complex language (Robinson 2001a, 2001b, in press). A different viewpoint is held by Skehan (1998) and Skehan & Foster (1999, 2001), who hypothesize that the more attention is required for a task because of its cognitive complexity, the less complex will be the linguistic output. The present research focuses on the relationship between taskcomplexity and linguistic performance in L1 and L2 writing. We report on an experiment carried out among 51 Dutch university students of Italian as a second language. The test included two writing tasks, in which cognitive task complexity was manipulated by varying the number of elements to be described and the required reasoning demands. Pre-existing knowledge of Italian was established by means of a pre-test. In the article, the results and theoretical and pedagogical implications of the study are discussed.
