This dissertation intends to examine the effects of task-induced involvement load on the L2 incidental vocabulary acquisition through reading. Task-induced involvement load is operationalized through manipulating the components of need, search and evaluation to show the relevance of L2 incidental vocabulary acquisition. It will intend to do this by using three major variables: task-induced involvement load, initial vocabulary learning and medium-term vocabulary retention. The chapter starts by providing reasons for why incidental vocabulary acquisition through reading has been the focus of this study. The chapter then continues by summarizing how the existing literature helped shape the focus on the Involvement Load Hypothesis in the current study. Finally, a general overview of the structure of this dissertation will be given in the last section.
