ABSTRACT
The affective component has been acknowledged as critical to understand information search behavior and user–computer interactions. There is a lack of studies that analyze the emotions that the user feels when searching for information about products with search engines. The present study analyzes the emotional outcomes of the online search process, taking into account the user’s (a) perceptions of success and effort exerted on the search process, (b) initial affective state, and (c) emotions felt during the search process. In addition, we identify profiles of online searchers based on the emotional outcomes of the search process, which allow us to differentiate the emotional processes and behavioral patterns that lead to such emotions. The results of the study stress the importance of the affective component of the online search behavior, given that these emotional outcomes are likely to influence all the subsequent actions that users perform on the Web.

ABSTRACT
This chapter focuses on on-line metacognitive processes, in particular, comprehension monitoring in reading. Interesting prospects of technology-supported on-line methods for metacognitive studies on comprehension monitoring are outlined on the basis of current empirical evidence. First, the on-line methods to study comprehension monitoring are described and discussed, and our studies of elementary (Grade 1–6) school students’ monitoring and regulating comprehension feature the application of two of the methods, namely traced silent reading and eyetracking. Second, these studies give evidence on young students’ comprehension monitoring and developmental trends as a function of grade, decoding skills, listening and reading comprehension skills and intervention. As an example, results from a recent study linking students’ comprehension monitoring, mood and metacognitive experiences are presented in more detail. The future promise and prospects of technology-supported on-line comprehension monitoring methods for metacognition research and of assessing affects associated with comprehension monitoring processes are discussed. It is argued that the modern technology allowing synchronized data collection of affective reactions and reading comprehension behavior offer important new opportunities to enhance current theories and empirical knowledge, particularly, of linkages between emotional and metacognitive processes.

ABSTRACT
Despite the word's common usage by gamers and reviewers alike, it is still not clear what immersion means. This paper explores immersion further by investigating whether immersion can be defined quantitatively, describing three experiments in total. The first experiment investigated participants' abilities to switch from an immersive to a non-immersive task. The second experiment investigated whether there were changes in participants' eye movements during an immersive task. The third experiment investigated the effect of an externally imposed pace of interaction on immersion and affective measures (state anxiety, positive affect, negative affect). Overall the findings suggest that immersion can be measured subjectively (through questionnaires) as well as objectively (task completion time, eye movements). Furthermore, immersion is not only viewed as a positive experience: negative emotions and uneasiness (i.e. anxiety) also run high.
