In the present research, we tested the impact of games on creativity and emotions in a between-subject online experiment with four conditions (N = 658). (1) participants played a simple puzzle game that allowed many solutions (priming divergent thinking); (2) participants played a short game that required one fitting solution (priming convergent thinking); (3) participants performed mental arithmetic; (4) passive control condition. Results show that divergent and convergent creativity were higher after playing games and lower after mental arithmetic. Positive emotions did not function as a mediator, even though they were also heightened after playing the games and lower after mental arithmetic. However, contrary to previous research, we found no direct effect of emotions, creative self-efficacy, and growth- vs. fixed on creative performance. We discuss practical implications for digital learning and application settings.}, language = {en} } @article{UygunClahsen2021, author = {Uygun, Serkan and Clahsen, Harald}, title = {Morphological processing in heritage speakers}, series = {Bilingualism : language and cognition}, volume = {24}, journal = {Bilingualism : language and cognition}, number = {3}, publisher = {Cambridge Univ.

Here we report results from a masked priming experiment with 97 bilingual (Turkish/German) heritage speakers and a control group of 40 non-heritage speakers of Turkish examining regular and irregular forms of the Turkish aorist. We found that, for the regular aorist, heritage speakers use the same morphological decomposition mechanism ('affix stripping') as control speakers, whereas for processing irregularly inflected forms they exhibited more variability (i.e., less homogeneous performance) than the control group. Heritage speakers also demonstrated semantic priming effects. At a more general level, these results indicate that heritage speakers draw on multiple sources of information for recognizing morphologically complex words.}, language = {en} } @article{SchneebergerEccard2021, author = {Schneeberger, Karin and Eccard, Jana}, title = {Experience of social density during early life is associated with attraction to conspecific odour in the common vole (Microtus arvalis)}, series = {Ethology : international journal of behavioural biology}, volume = {127}, journal = {Ethology : international journal of behavioural biology}, number = {10}, publisher = {Wiley-Blackwell}, address = {Berlin}, issn = {0179-1613}, doi = {10.1111/eth.13211}, pages = {908 -- 913}, year = {2021}, abstract = {Social organisation in species with fluctuating population sizes can change with density.

We used common voles (Microtus arvalis), a rodent species undergoing extreme density fluctuations. We found that individuals originating from high experimental density populations kept in large outdoor enclosures invested more time in inspecting conspecific olfactory cues than individuals from low-density populations. Generally, voles from both treatments spent more time with the olfactory cues than expected by chance and did not differ in their latency to approach the odour samples. Our findings indicate either that early experience affects odour sensitivity or that animals evaluate the social information contained in conspecific odours differently, depending on their early life experience of conspecific density.}, language = {en} } @article{CastellanosFriedrichPetrovicetal.2020, author = {Castellanos, Reynel Urrea and Friedrich, Thomas and Petrovic, Nevena and Altmann, Simone and Brzezinka, Krzysztof and Gorka, Michal and Graf, Alexander and B{\"a}urle, Isabel}, title = {FORGETTER2 protein phosphatase and phospholipase D modulate heat stress memory in Arabidopsis}, series = {The plant journal}, volume = {104}, journal = {The plant journal}, number = {1}, publisher = {Wiley}, address = {Hoboken}, issn = {0960-7412}, doi = {10.1111/tpj.14927}, pages = {7 -- 17}, year = {2020}, abstract = {Plants can mitigate environmental stress conditions through acclimation.

FGT2 interacts with phospholipase D alpha 2 (PLD alpha 2), which is involved in the metabolism of membrane phospholipids and is also required for HS memory.

To cope with these conditions, plants can remember a previous stress, which allows them to respond more efficiently to a subsequent stress, a phenomenon known as priming. This ability can be maintained at the somatic level for a few days or weeks after the stress is perceived, suggesting that plants can store information of a past stress during this recovery phase. While the immediate responses to a single stress event have been extensively studied, knowledge on priming effects and how stress memory is stored is still scarce. At the molecular level, memory of a past condition often involves changes in chromatin structure and organization, which may be maintained independently from transcription.

Here, we demonstrate that foliar application of an extract from the seaweed Ascophyllum nodosum, SuperFifty (SF), largely prevents paraquat (PQ)-induced oxidative stress in Arabidopsis thaliana. While PQ-stressed plants develop necrotic lesions, plants pre-treated with SF (i.e., primed plants) were unaffected by PQ. Transcriptome analysis revealed induction of reactive oxygen species (ROS) marker genes, genes involved in ROS-induced programmed cell death, and autophagy-related genes after PQ treatment. These changes did not occur in PQ-stressed plants primed with SF. In contrast, upregulation of several carbohydrate metabolism genes, growth, and hormone signaling as well as antioxidant-related genes were specific to SF-primed plants. Metabolomic analyses revealed accumulation of the stress-protective metabolite maltose and the tricarboxylic acid cycle intermediates fumarate and malate in SF-primed plants. Lipidome analysis indicated that those lipids associated with oxidative stress-induced cell death and chloroplast degradation, such as triacylglycerols (TAGs), declined upon SF priming. Our study demonstrated that SF confers tolerance to PQ-induced oxidative stress in A. thaliana, an effect achieved by modulating a range of processes at the transcriptomic, metabolic, and lipid levels.}, language = {en} } @article{FarhyVerissimo2019, author = {Farhy, Yael and Verissimo, Joao Marques}, title = {Semantic Effects in Morphological Priming: The Case of Hebrew Stems}, series = {Language and speech}, volume = {62}, journal = {Language and speech}, number = {4}, publisher = {Sage Publ.}, address = {London}, issn = {0023-8309}, doi = {10.1177/0023830918811863}, pages = {737 -- 750}, year = {2019}, abstract = {To what extent is morphological representation in different languages dependent on semantic information? Unlike Indo-European languages, the Semitic mental lexicon has been argued to be purely "morphologically driven", with complex stems represented in a decomposed format (root + vowel pattern) irrespectively of their semantic properties. We have examined this claim by comparing cross-modal root-priming effects elicited by Hebrew verbs of a productive, open-ended class (Piel) and verbs of a closed-class (Paal). Morphological priming effects were obtained for both verb types, but prime-target semantic relatedness interacted with class, and only modulated responses following Paal, but not Piel primes. We explain these results by postulating different types of morpho-lexical representation for the different classes: structured stems, in the case of Piel, and whole-stems (which lack internal morphological structure), in the case of Paal. We conclude that semantic effects in morphological priming are also obtained in Semitic languages, but they are crucially dependent on type of morpho-lexical representation.}, language = {en} } @article{CreetMorrisHowardetal.2019, author = {Creet, Ella and Morris, Julie and Howard, David and Nickels, Lyndsey}, title = {Name it again! investigating the effects of repeated naming attempts in aphasia}, series = {Aphasiology : an international, interdisciplinary journal}, volume = {33}, journal = {Aphasiology : an international, interdisciplinary journal}, number = {10}, publisher = {Routledge, Taylor \& Francis Group}, address = {Abingdon}, issn = {0268-7038}, doi = {10.1080/02687038.2019.1622352}, pages = {1202 -- 1226}, year = {2019}, language = {en} } @article{Gerstenberg2019, author = {Gerstenberg, Annette}, title = {Generational styles in oral storytelling}, series = {Narrative inquiry}, volume = {29}, journal = {Narrative inquiry}, number = {1}, publisher = {John Benjamins Publishing Co.}, address = {Amsterdam}, issn = {1387-6740}, doi = {10.1075/ni.18042.ger}, pages = {1 -- 28}, year = {2019}, abstract = {When it comes to autobiographical narratives, the most spontaneous and natural manner is preferable.

During evolution, plants have established mechanisms to orchestrate the delicate balance between growth and stress tolerance, to reset cellular biochemistry once stress vanishes, or to keep a molecular memory, which enables survival of a harsher stress that may arise later. Although there are several examples of memory in diverse plants species, the molecular machinery underlying the formation, duration, and resetting of stress memories is largely unknown so far. We report here that autophagy, a central self-degradative process, assists in resetting cellular memory of heat stress (HS) in Arabidopsis thaliana. Autophagy is induced by thermopriming (moderate HS) and, intriguingly, remains high long after stress termination. We demonstrate that autophagy mediates the specific degradation of heat shock proteins at later stages of the thermorecovery phase leading to the accumulation of protein aggregates after the second HS and a compromised heat tolerance. Autophagy mutants retain heat shock proteins longer than wild type and concomitantly display improved thermomemory. Our findings reveal a novel regulatory mechanism for HS memory in plants.}, language = {en} }
