In this study, we investigate various eye-movement measures during reading of text with experimentally manipulated layout (word-wise and letter-wise mirrored-reversed text as well as inverted and scrambled text). While typical findings (e.g., longer mean fixation times, shorter mean saccades lengths) in reading manipulated texts compared to normal texts were reported in earlier work, little is known about changes of oculomotor targeting observed in within-word landing positions under the above text layouts. Here we carry out precise analyses of landing positions and find substantial changes in the so-called launch-site effect in addition to the expected overall slow-down of reading performance. Specifically, during reading of our manipulated text conditions with reversed letter order (against overall reading direction), we find a reduced launch-site effect, while in all other manipulated text conditions, we observe an increased launch-site effect. Our results clearly indicate that the oculomotor system is highly adaptive when confronted with unusual reading conditions.}, language = {en} } @article{Gaertner2018, author = {G{\"a}rtner, Ursula}, title = {nempe exemplis discimus}, series = {Antike Erz{\"a}hl- und Deutungsmuster : Zwischen Exemplarit{\"a}t und Transformation}, volume = {374}, journal = {Antike Erz{\"a}hl- und Deutungsmuster : Zwischen Exemplarit{\"a}t und Transformation}, publisher = {De Gruyter}, address = {Berlin}, isbn = {978-3-11-061251-6}, issn = {1616-0452}, doi = {10.1515/9783110612516-022}, pages = {455 -- 472}, year = {2018}, abstract = {'Tradition' and 'example' are key concepts of the ancient fable. The fable has not only developed a literary tradition of its own, but from the beginning, it was also used as a rhetorical device, the exemplum. A diachronic overview of the genre and especially the use of the fable as exemplum reveals that Phaedrus adapts these terms in a new and ingenious way. In a case study of fable 3.9 this paper demonstrates how the fable finds its place in the literary tradition of the motif, how Socrates is presented as a model for the poet's persona and how an intricate network of inter- and intratextual references is established between Socrates, Aesop, Phaedrus, and his potential successors. The subtle irony of the poet is particularly evident in the gradual development of the poet's persona into a caricature, but the message of the fable itself remains unaffected: the value of true friendship.}, language = {en} } @article{HeuerOrland2019, author = {Heuer, Leonie and Orland, Andreas}, title = {Cooperation in the Prisoner's Dilemma}, series = {Royal Society Open Science}, volume = {6}, journal = {Royal Society Open Science}, publisher = {Royal Soc.

This article presents a comparison between subjects restricted to playing pure strategies and subjects allowed to play mixed strategies in a one-shot symmetric PD laboratory experiment. Subjects interact with 10 other subjects and take their decisions all at once. Because subjects in the mixed-strategy treatment group are allowed to condition their level of cooperation more precisely on their beliefs about their counterparts' level of cooperation, we predicted the cooperation rate in the mixed-strategy treatment group to be higher than in the pure-strategy control group. The results of our experiment reject our prediction: even after controlling for beliefs about the other subjects' level of cooperation, we find that cooperation in the mixed-strategy group is lower than in the pure-strategy group. We also find, however, that subjects in the mixedstrategy group condition their cooperative behaviour more closely on their beliefs than in the pure-strategy group. In the mixed-strategy group, most subjects choose intermediate levels of cooperation.}, language = {en} } @article{KuehneJeglinskiMende2023, author = {K{\"u}hne, Katharina and Jeglinski-Mende, Melinda A.}, title = {Refraining from interaction can decrease fear of physical closeness during COVID-19}, series = {Scientific reports}, volume = {13}, journal = {Scientific reports}, number = {1}, publisher = {Nature portfolio}, address = {London}, issn = {2045-2322}, doi = {10.1038/s41598-023-34667-x}, pages = {12}, year = {2023}, abstract = {Perception of peripersonal space (PPS) and interpersonal distance (IPD) has been shown to be modified by external factors such as perceived danger, the use of tools, and social factors. Especially in times of social distancing in the context of the COVID-19 pandemic, it is vital to study factors that modify PPS and IPD. The present work addresses the question of whether wearing a face mask as a protection tool and social interaction impact the perception of IPD. We tested estimated IPD in pictures at three distances: 50 cm, 90 cm, and 150 cm in both social interaction (shaking hands) and without interaction and when the two people in the pictures wore a face mask or not. Data from 60 subjects were analyzed in a linear mixed model (on both difference in distance estimation to the depicted distance and in absolute distance estimation) and in a 3 (distance: 50, 90, 150) x 2 (interaction: no interaction, shake hands), x 2 face mask (no mask, mask) rmANOVA on distance estimation difference. All analyses showed that at a distance of 50 and 90 cm, participants generally underestimated the IPD while at an IPD of 150 cm, participants overestimated the distance. This could be grounded in perceived danger and avoidance behavior at closer distances, while the wider distance between persons was not perceived as dangerous. Our findings at an IPD of 90 cm show that social interaction has the largest effect at the border of our PPS, while the face mask did not affect social interaction at either distance. In addition, the ANOVA results indicate that when no social interaction was displayed, participants felt less unsafe when depicted persons wore a face mask at distances of 90 and 150 cm. This shows that participants are on the one hand aware of the given safety measures and internalized them; on the other hand, that refraining from physical social interaction helps to get close to other persons.}, language = {en} } @article{RodriguezSanchezWucherpfennigRischkeetal.2023, author = {Rodr{\´i}guez S{\´a}nchez, Alejandra and Wucherpfennig, Julian and Rischke, Ramona and Iacus, Stefano Maria}, title = {Search-and-rescue in the Central Mediterranean Route does not induce migration}, series = {Scientific reports}, volume = {13}, journal = {Scientific reports}, number = {1}, publisher = {Macmillan Publishers Limited, part of Springer Nature}, address = {London}, issn = {2045-2322}, doi = {10.1038/s41598-023-38119-4}, pages = {1}, year = {2023}, abstract = {State- and private-led search-and-rescue are hypothesized to foster irregular migration (and thereby migrant fatalities) by altering the decision calculus associated with the journey. We here investigate this 'pull factor' claim by focusing on the Central Mediterranean route, the most frequented and deadly irregular migration route towards Europe during the past decade. Based on three intervention periods—(1) state-led Mare Nostrum, (2) private-led search-and-rescue, and (3) coordinated pushbacks by the Libyan Coast Guard—which correspond to substantial changes in laws, policies, and practices of search-and-rescue in the Mediterranean, we are able to test the 'pull factor' claim by employing an innovative machine learning method in combination with causal inference. We employ a Bayesian structural time-series model to estimate the effects of these three intervention periods on the migration flow as measured by crossing attempts (i.e., time-series aggregate counts of arrivals, pushbacks, and deaths), adjusting for various known drivers of irregular migration. We combine multiple sources of traditional and non-traditional data to build a synthetic, predicted counterfactual flow. Results show that our predictive modeling approach accurately captures the behavior of the target time-series during the various pre-intervention periods of interest. A comparison of the observed and predicted counterfactual time-series in the post-intervention periods suggest that pushback policies did affect the migration flow, but that the search-and-rescue periods did not yield a discernible difference between the observed and the predicted counterfactual number of crossing attempts. Hence we do not find support for search-and-rescue as a driver of irregular migration. In general, this modeling approach lends itself to forecasting migration flows with the goal of answering causal queries in migration research.}, language = {en} } @article{VinkeGabryschPaolettietal.2020, author = {Vinke, Kira and Gabrysch, Sabine and Paoletti, Emanuela and Rockstr{\"o}m, Johan and Schellnhuber, Hans Joachim}, title = {Corona and the climate}, series = {Global sustainability}, volume = {3}, journal = {Global sustainability}, publisher = {Cambridge Univ.
