The study also intends to examine the effects of manipulating task complexity on leaners‘ task motivation. Finally, the current study seeks to explore the relationship between the complexity of language production and task motivation when task complexity was manipulated. This study draws on the construct of cognitive complexity from Robinson‘s Cognition Hypothesis (Robinson 2001a, 2003a, 2003b, 2005, 2007a, 2007b) which predicts that more cognitively complex tasks along resource-directing dimension and simpler tasks on resource-dispersing dimension will lead to a greater complexity of language production. However, research on the effects of manipulating task complexity along both resource-directing and resource-dispersing dimensions is so far inconclusive. The current study sought to fill this gap based on Cognition Hypothesis, by looking at the synergistic effects of increases and decreases task complexity on written language production and task motivation.   The participants were 88 engineering learners at a technical university in Malaysia who enrolled in English for Professional Communication course. The participants were placed in four separate groups that were categorized as follows; i) with causal reasoning demand (+CRD), ii) without causal reasoning demand (–CRD), iii) with task structure (+TS), and iv) without task structure (–TS). Each learner engaged in a one-hour session of a writing task for which they had to write an essay on Wiki on miscommunication issues at the workplace. After the participants completed the writing tasks, they were asked to complete a questionnaire to gauge their motivation towards the tasks and several participants from each group were interviewed. The statistics from the essay writing and input from the questionnaire served as the data in the current study. The essay writings were saved and analysed to determine the role of these task implementation features on the complexity of language production. The complexity of the language was analysed using two measures: syntactic complexity (i.e. T-unit complexity ratio, sentence complexity ratio, dependent clause ratio and dependent clause per T-unit) and lexical complexity (i.e. word type ratio, Guiraud Index and lexical sophistication).   Results showed that the two implementation features (+/- CRD and +/- TS) influenced the complexity of the language production. The findings on the effect of task complexity on task motivation demonstrated that neither the reasoning demand nor the task structure affected learners‘ motivation towards the task. The findings on the relationship between task complexity and task motivation revealed a significant correlation between manipulating the cognitive demand of a task and the lexical production of the language. However, no correlation was found between task complexity and syntactic complexity of language production.20aCentre for Modern Languages and Human SciencesxDissertations 0aUniversities and CollegesxDissertations 0aTheses40uhttp://ecollib.ump.edu.my/3533/zLibrary access only  00102lcc4071a10000b10000d2019-09-04l0oCD 9629 | PBMSK .U45 2015 r Thesisp0000107739r2023-01-30 00:00:00t1w2019-09-04yTHESIS  00102lcc40718REFa10000b10000d2019-09-04l0oPBMSK .U45 2015 r Thesisp0000107738r2019-09-04 00:00:00t1w2019-09-04yTHESIS  aVIRTUA40c6488d6494  aVTLSSORT0080*0200*0400*0900*1000*2450*2600*3000*5000*5020*5040*5200*6100*6500*6501*8560*9992
