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{MartinHerppichRoscheretal.2019, author = {Martin, Craig E. and Herppich, Werner B. and Roscher, Yvonne and Burkart, Michael}, title = {Relationships between leaf succulence and Crassulacean acid metabolism in the genus Sansevieria (Asparagaceae)}, series = {Flora : morphology, distribution, functional ecology of plants}, volume = {261}, journal = {Flora : morphology, distribution, functional ecology of plants}, publisher = {Elsevier}, address = {M{\"u}nchen}, issn = {0367-2530}, doi = {10.1016/j.flora.2019.151489}, pages = {8}, year = {2019}, abstract = {Relationships between different measures of succulence and Crassulacean acid metabolism (CAM; defined here as nocturnal increases in tissue acidity) were investigated in leaves of ten species of Sansevieria under greenhouse conditions. CAM was found in seven of the ten species investigated, and CAM correlated negatively with leaf thickness and leaf hydrenchyma/chlorenchyma ratio. Similarly, CAM correlated negatively with leaf water content, but only when expressed on a fresh mass basis. CAM was not correlated with "mesophyll succulence", but weakly with leaf chlorophyll concentration. These results indicate that CAM is associated more with "all-cell succulence" and not with the amount of leaf hydrenchyma in the genus Sansevieria. The findings of this study emphasize the importance of defining the nature of "leaf succulence" in studies of photosynthetic pathways and leaf morphology. Evidence is also provided that CAM and succulence arose multiple times in the genus Sansevieria.}, language = {en} } @article{BuddPaulmannBarryetal.2015, author = {Budd, Mary-Jane and Paulmann, Silke and Barry, Christopher and Clahsen, Harald}, title = {Producing morphologically complex words: An ERP study with children and adults}, series = {Developmental cognitive neuroscience : a journal for cognitive, affective and social developmental neuroscience}, volume = {12}, journal = {Developmental cognitive neuroscience : a journal for cognitive, affective and social developmental neuroscience}, publisher = {Elsevier}, address = {Oxford}, issn = {1878-9293}, doi = {10.1016/j.dcn.2014.11.002}, pages = {51 -- 60}, year = {2015}, abstract = {widely studied morphological phenomenon in psycholinguistic research is the plurals-inside-compounds effect in English, which is the avoidance of regular plural modifiers within compounds (e.g., *rats hunter). The current study employs event-related brain potentials (ERPs) to investigate the production of plurals-inside-compounds in children and adults. We specifically examined the ERP correlates of producing morphologically complex words in 8-year-olds, 12-year-olds and adults, by recording ERPs during the silent production of compounds with plural or singular modifiers. Results for both children and adults revealed a negativity in response to compounds produced from regular plural forms when compared to compounds formed from irregular plurals, indicating a highly specific brain response to a subtle linguistic contrast. Although children performed behaviourally with an adult-like pattern in the task, we found a broader distribution and a considerably later latency in children's brain potentials than in adults', indicating that even in late childhood the brain networks involved in language processing are subject to subtle developmental changes.

Processing of time reference inflection in agrammatic and healthy speakers of German}, series = {Neuropsychologia : an international journal in behavioural and cognitive neuroscience}, volume = {65}, journal = {Neuropsychologia : an international journal in behavioural and cognitive neuroscience}, publisher = {Elsevier}, address = {Oxford}, issn = {0028-3932}, doi = {10.1016/j.neuropsychologia.2014.10.026}, pages = {180 -- 190}, year = {2014}, abstract = {Background: Individuals with agrammatic aphasia (IWAs) have problems with grammatical decoding of tense inflection. However, these difficulties depend on the time frame that the tense refers to. Verb morphology with reference to the past is more difficult than with reference to the non-past, because a link needs to be made to the past event in discourse, as captured in the PAst Discourse Linking Hypothesis (PADILIH; Bastiaanse, R., Bamyaci, E., Hsu, C., Lee, J., Yarbay Duman, T., Thompson, C. K., 2011. Time reference in agrammatic aphasia: A cross-linguistic study. J. Neurolinguist. 24, 652-673). With respect to reference to the (non-discourse-linked) future, data so far indicate that IWAs experience less difficulties as compared to past time reference (Bastiaanse, R., Bamyaci, E., Hsu, C., Lee, J., Yarbay Duman, T., Thompson, C. K., 2011. Time reference in agrammatic aphasia: A cross-linguistic study. J. Neurolinguist. 24, 652-673), supporting the assumptions of the PADILIH. Previous online studies of time reference in aphasia used methods such as reaction times analysis (e.g., Faroqi-Shah, Y., Dickey, M. W., 2009. On-line processing of tense and temporality in agrammatic aphasia. Brain Lang. 108, 97-111). So far, no such study used eye-tracking, even though this technique can bring additional insights (Burchert, F., Hanne, S., Vasishth, S., 2013. Sentence comprehension disorders in aphasia: the concept of chance performance revisited. Aphasiology 27, 112-125, doi:10.1080/02687038.2012.730603). Aims: This study investigated (1) whether processing of future and past time reference inflection differs between non-brain-damaged individuals (NBDs) and IWAs, and (2) underlying mechanisms of time reference comprehension failure by IWAs. Results and discussion: NBDs scored at ceiling and significantly higher than the IWAs. IWAs had below-ceiling performance on the future condition, and both participant groups were faster to respond to the past than to the future condition. These differences are attributed to a pre-existing preference to look at a past picture, which has to be overcome. Eye movement patterns suggest that both groups interpret future time reference similarly, while IWAs show a delay relative to NBDs in interpreting past time reference inflection. The eye tracking results support the PADILIH, because processing reference to the past in discourse syntax requires additional resources and thus, is problematic and delayed for people with aphasia.

A reloading of the polyplexes can be observed by adding the unmodified PEI samples of different molar mass. In excess of PEI a morphological transition from core-shell particles (at N/P 8) to loosely packed onion-like polyplexes (at N/P 40) is observed. The shift of the DSC melting peak from 88 degrees C to 76 degrees C indicates a destabilization of the DNA double helix due to the complexation with the unmodified PEI. Experiments with the maltose-modified PEI show a reloading already at a lower N/P ratio. Due to the presence of the sugar units in the periphery of the polycation electrostatic interactions between DNA become weaker, but cooperative H-bonding forces are reinforced. The resulting less-toxic, more compact polyplexes in excess of the PEI-Mal with two melting points and well distributed DNA segments are of special interest for extended gene delivery experiments.

Subsequently, another visual stimulus cued participants for an overt vocalization of their response. ERP results for the adult group revealed a negativity 300-450 ms after the silent-production cue for regular compared to irregular past-tense forms.
