One line of research examines how adult readers identify compound words during reading. The other line of research deals with how a specific reading goal influences the way long expository texts are read. Both lines of research are conducted using Finnish as the source language. With respect to the first research question, it is demonstrated that compound words are recognized either holistically or via their components, depending on the length of the compound word. Readers begin to process whatever information is readily available in the foveal vision(i.e., either the whole-word form or the initial component). The second line of research demonstrates that(1)a specific reading goal is capable of exerting an early effect on readers’ eye fixation patterns,(2)time course analyses based on eye movement patterns can reveal interesting individual differences, and(3)working memory capacity is linked to the efficiency to strategically allocate attention as well as to encode information to and retrieve it from the long-term memory. It is concluded that the eye-tracking technique is an excellent research tool to tap into the workings of the human mind during the comprehension of written texts.展开更多

This paper reports a Mandarin monologue speech corpus-study, anexperimental phonetic attempt to conduct a study on the pitch of trisyllabic prosodicwords in Mandarin monologue. In addition, taking the characteristics of Englishprosodic words into consideration, the paper makes a contrastive analysis of prosodicwords in English and Mandarin. This study finds that the pitch of trisyllabic prosodicwords in Mandarin is inevitably affected by structural factors. As far as the leftsyllable is concerned, the grammatical category, prosodic hierarchical boundary andthe position of the intonational phrase where the syllable is located, the mid syllableand the right syllable may have influences on the pitch contour of the left syllable.As to the mid syllable, the grammatical category, the left syllable, the right syllableand the position of the intonational phrase where the syllable is located may haveinfluences on the pitch contour of the mid syllable. As for the right syllable, theprosodic hierarchical boundary where the syllable is located and the mid syllable mayhave effects on the pitch contour of the right syllable. Different from the previousfindings of the study on read corpus, this study shows that the mid syllable not onlyhas dissimilatory effects but also has assimilatory effects on the pitch of its precedingsyllable. The left syllable has anticipatory effects on the onset pitch of the mid syllableand the right syllable has coarticulation effects on the offset pitch of the mid syllable.展开更多
