Whereas the influence of orthographic or phonological parafoveal information on gaze control is undisputed, there has been no reliable evidence for early parafoveal extraction of semantic information in alphabetic script. Using a novel combination of the gaze- contingent fast-priming and boundary paradigms, we demonstrate semantic preview benefit when a semantically related parafoveal word was available during the initial 125 ms of a fixation on the pretarget word (Experiments 1 and 2). When the target location was made more salient, significant parafoveal semantic priming occurred only at 80 ms (Experiment 3). Finally, with short primes only (20, 40, 60 ms), effects were not significant but were numerically in the expected direction for 40 and 60 ms (Experiment 4). In all experiments, fixation durations on the target word increased with prime durations under all conditions. The evidence for extraction of semantic information from the parafoveal word favors an explanation in terms of parallel word processing in reading.}, language = {en} } @article{YanKlieglRichteretal.2010, author = {Yan, Ming and Kliegl, Reinhold and Richter, Eike M. and Nuthmann, Antje and Shu, Hua}, title = {Flexible saccade-target selection in Chinese reading}, issn = {1747-0218}, doi = {10.1080/17470210903114858}, year = {2010}, abstract = {As Chinese is written without orthographical word boundaries (i.e., spaces), it is unclear whether saccade targets are selected on the basis of characters or words and whether saccades are aimed at the beginning or the centre of words. Here, we report an experiment where 30 Chinese readers read 150 sentences while their eye movements were monitored. They exhibited a strong tendency to fixate at the word centre in single-fixation cases and at the word beginning in multiple-fixation cases. Different from spaced alphabetic script, initial fixations falling at the end of words were no more likely to be followed by a refixation than initial fixations at word centre. Further, single fixations were shorter than first fixations in two-fixation cases, which is opposite to what is found in Roman script. We propose that Chinese readers dynamically select the beginning or centre of words as saccade targets depending on failure or success with segmentation of parafoveal word boundaries.}, language = {en} } @article{Schwarz2010, author = {Schwarz, Wolfgang}, title = {Comparing continuous and discrete birthday coincidences : "Same-Day" versus "Within 24 Hours"}, issn = {0003-1305}, doi = {10.1198/tast.2009.09003}, year = {2010}, abstract = {In its classical form the famous birthday problem (Feller 1968; Mosteller 1987) addresses coincidences within a discrete sample space, looking at births that fall on the same calendar day.

We observe that distributions of landing positions in skipping saccades show an increased leftward shift compared to non-skipping saccades at equal launch-site distances. Using an improved algorithm for the estimation of mislocated fixations, we demonstrate the reliability of our results.}, language = {en} } @article{NuthmannSmithEngbertetal.2010, author = {Nuthmann, Antje and Smith, Tim J. and Engbert, Ralf and Henderson, John M.}, title = {CRISP: a computational model of fixation duration in scene viewing}, year = {2010}, abstract = {Eye-movement control during scene viewing can be represented as a series of individual decisions about where and when to move the eyes. While substantial behavioral and computational research has been devoted to investigating the placement of fixations in scenes, relatively little is known about the mechanisms that control fixation durations. Here, we propose a computational model (CRISP) that accounts for saccade timing and programming and thus for variations in fixation durations in scene viewing. First, timing signals are modeled as continuous-time random walks. Second, difficulties at the level of visual and cognitive processing can inhibit and thus modulate saccade timing. Inhibition generates moment-by-moment changes in the random walk's transition rate and processing-related saccade cancellation. Third, saccade programming is completed in 2 stages: an initial, labile stage that is subject to cancellation and a subsequent, nonlabile stage. Several simulation studies tested the model's adequacy and generality. An initial simulation study explored the role of cognitive factors in scene viewing by examining how fixation durations differed under different viewing task instructions. Additional simulations investigated the degree to which fixation durations were under direct moment-to-moment control of the current visual scene. The present work further supports the conclusion that fixation durations, to a certain degree, reflect perceptual and cognitive activity in scene viewing. Computational model simulations contribute to an understanding of the underlying processes of gaze control.}, language = {en} } @article{Rauh2010, author = {Rauh, Hellgard}, title = {Entwicklungspsychologische Grundlagen II : das Kleinstkind}, isbn = {978-3-17-020957-2}, year = {2010}, language = {de} } @article{SpoererGlaser2010, author = {Sp{\"o}rer, Nadine and Glaser, Cornelia}, title = {F{\"o}rderung selbstregulierten Lernens im schulischen Kontext}, issn = {1010-0652}, doi = {10.1024/1010-0652/A000014}, year = {2010}, abstract = {Selbstreguliertes Lernen umfasst gedankliche und verhaltensbezogene Aktivit{\"a}ten, die Lernende dazu bef{\"a}higen, aufgabenspezifische Fertigkeiten effizient erwerben sowie wirksam und nachhaltig einsetzen zu k{\"o}nnen.

We show that for Posner cuing with saccadic responses, microsaccades go with attention in at least 75\% of cases (almost 90\% if probability matching is assumed) when they are first (or only) microsaccades in the cue target interval and when they occur between 200 and 400 msec after the cue. The relation between spatial attention and the direction of microsaccades drops to chance level for unselected microsaccades collected during manual-response conditions. Analyses of data from four cross-modal cuing experiments demonstrate an above-chance, intermediate link for visual cues, but no systematic relation for auditory cues. Thus, the link between spatial attention and direction of microsaccades depends on the experimental condition and time of occurrence, but it can be very strong.}, language = {en} }
