Yayın The function of regressions in reading: Backward eye movements allow rereading(Springer, 2013-01) Booth, Robert William; Weger, Ulrich W.Standard text reading involves frequent eye movements that go against normal reading order. The function of these "regressions" is still largely unknown. The most obvious explanation is that regressions allow for the rereading of previously fixated words. Alternatively, physically returning the eyes to a word's location could cue the reader's memory for that word, effectively aiding the comprehension process via location priming (the "deictic pointer hypothesis"). In Experiment 1, regression frequency was reduced when readers knew that information was no longer available for rereading. In Experiment 2, readers listened to auditorily presented text while moving their eyes across visual placeholders on the screen. Here, rereading was impossible, but deictic pointers remained available, yet the readers did not make targeted regressions in this experiment. In Experiment 3, target words in normal sentences were changed after reading. Where the eyes later regressed to these words, participants generally remained unaware of the change, and their answers to comprehension questions indicated that the new meaning of the changed word was what determined their sentence representations. These results suggest that readers use regressions to reread words and not to cue their memory for previously read words.Yayın The internet and political participation : exploring the explanatory links(Sage Publications Ltd, 2005-12) Karakaya Polat, RabiaThere is a growing literature exploring the role of the Internet in influencing levels and styles of political participation. However, it is not yet clear why the Internet is perceived as a medium that can, at least potentially, increase participation. Moreover, putting the emphasis on the Internet as a technology rather than on its information and communication capabilities signals a tendency for technological determinism. In order to avoid this, the article explores the relation between the Internet and political participation by examining three different facets of the Internet: the Internet as an information source, as a communication medium and as a virtual public sphere. The main argument of the article is that it is these facets of the Internet that may affect levels and styles of political participation and hence are of interest for political scientists. The article also emphasizes the relevance of established theories of participation within political science in evaluating the potential role of the Internet for affecting levels and styles of political participation.Yayın Uncontrolled avoidance of threat: Vigilance-avoidance, executive control, inhibition and shifting(Routledge Journals, 2014) Booth, Robert WilliamIt has been argued that anxious individuals orient their attention initially towards and then away from threat; this pattern is known as vigilance-avoidance. While the mechanisms underlying the initial vigilance have been subject to intense speculation and study, mechanisms underlying any subsequent avoidance have been neglected, although it has often been assumed that avoidance is a controlled coping strategy. Using a correlational design, the present study assessed avoidance in a dot-probe task, along with anxiety and two aspects of goal-driven executive control: Shifting and inhibition. Avoidance of threat correlated with state of anxiety; separate from this, avoidance also correlated negatively with shifting performance and was unrelated to inhibition performance. In other words, avoidance appeared to represent a shifting failure in this study. These results suggest that avoidance may occur ballistically in any individual as a consequence of threat exposure and does not necessarily represent a controlled coping response.
