Task demands and individual differences have been linked reliably to word skipping during reading. Such differences in fixation probability may imply a selection effect for multivariate analyses of eye-movement corpora if selection effects correlate with word properties of skipped words. For example, with fewer fixations on short and highly frequent words the power to detect parafoveal-on-foveal effects is reduced. We demonstrate that increasing the fixation probability on function words with a manipulation of the expected difficulty and frequency of questions reduces an age difference in skipping probability (i.e., old adults become comparable to young adults) and helps to uncover significant parafoveal-on-foveal effects in this group of old adults. We discuss implications for the comparison of results of eye-movement research based on multivariate analysis of corpus data with those from display-contingent manipulations of target words.
Throughout its empirical research history eye movement research has always been aware of the differences in reading behavior induced by individual differences and task demands. This work introduces a novel comprehensive concept of reading strategy, comprising individual differences in reading style and reading skill as well as reader goals. In a series of sentence reading experiments recording eye movements, the influence of reading strategies on reader- and word-level effects assuming distributed processing has been investigated. Results provide evidence for strategic, top-down influences on eye movement control that extend our understanding of eye guidance in reading.

Matching participants (as suggested by Hope, 2015) may be one promising option for research on a potential bilingual advantage in executive functions (EF). In this study we first compared performances in three EF-tasks of a naturally heterogeneous sample of monolingual (n = 69, age = 9.0 y) and multilingual children (n = 57, age = 9.3 y). Secondly, we meticulously matched participants pairwise to obtain two highly homogeneous groups to rerun our analysis and investigate a potential bilingual advantage. The initally disadvantaged multilinguals (regarding socioeconomic status and German lexicon size) performed worse in updating and response inhibition, but similarly in interference inhibition. This indicates that superior EF compensate for the detrimental effects of the background variables. After matching children pairwise on age, gender, intelligence, socioeconomic status and German lexicon size, performances became similar except for interference inhibition. Here, an advantage for multilinguals in the form of globally reduced reaction times emerged, indicating a bilingual executive processing advantage.

Das 9. Herbsttreffen Patholinguistik mit dem Schwerpunktthema "Lauter Laute: Phonologische Verarbeitung und Lautwahrnehmung in der Sprachtherapie" fand am 14.11.2015 in Potsdam statt. Das Herbsttreffen wird seit 2007 jährlich vom Verband für Patholinguistik e.V. (vpl) durchgeführt. Der vorliegende Tagungsband beinhaltet die vier Hauptvorträge zum Schwerpunktthema, die drei Kurzvorträge aus dem Spektrum Patholinguisitk sowie die Beiträge der Posterpräsentationen zu weiteren Themen aus der sprachtherapeutischen Forschung und Praxis.
"Spektrum Patholinguistik" (Band 2) ist der Tagungsband zum 2. Herbsttreffen Patholinguistik, das der Verband für Patholinguistik (vpl) e.V. am 22.11.2008 an der Universität Potsdam veranstaltet hat. Zum Schwerpunktthema "Ein Kopf - Zwei Sprachen: Mehrsprachigkeit in Forschung und Therapie" sind die drei Hauptvorträge und vier Abstracts von Posterpräsentationen veröffentlicht. Desweiteren enthält der Tagungsband freie Beiträge, u.a. zu Satzverarbeitung und Agrammatismus, Lesestrategien und LRS, Prosodie-Entwicklung, kindlichen Aphasien, Dysphagie-Therapie sowie zu kognitiven Defiziten bei älteren Menschen.
