  abstract  = {This study presents results from a cross-modal priming experiment investigating inflected verb forms of German. A group of late learners of German with Russian as their native language (L1) was compared to a control group of German L1 speakers. The experiment showed different priming patterns for the two participant groups. The L1 German data yielded a stem-priming effect for inflected forms involving regular affixation and a partial priming effect for irregular forms irrespective of stem allomorphy. By contrast, the data from the late bilinguals showed reduced priming effects for both regular and irregular forms. We argue that late learners rely more on lexically stored inflected word forms during word recognition and less on morphological parsing than native speakers.},

  abstract  = {The current study investigates to what extent masked morphological priming is modulated by language-particular properties, specifically by its writing system. We present results from two masked priming experiments investigating the processing of complex Japanese words written in less common (moraic) scripts. In Experiment 1, participants performed lexical decisions on target verbs; these were preceded by primes which were either (i) a past-tense form of the same verb, (ii) a stem-related form with the epenthetic vowel-i, (iii) a semantically-related form, and (iv) a phonologically-related form. Significant priming effects were obtained for prime types (i), (ii), and (iii), but not for (iv). This pattern of results differs from previous findings on languages with alphabetic scripts, which found reliable masked priming effects for morphologically related prime/target pairs of type (i), but not for non-affixal and semantically-related primes of types (ii), and (iii). In Experiment 2, we measured priming effects for prime/target pairs which are neither morphologically, semantically, phonologically nor - as presented in their moraic scripts orthographically related, but which in their commonly written form share the same kanji, which are logograms adopted from Chinese. The results showed a significant priming effect, with faster lexical-decision times for kanji-related prime/target pairs relative to unrelated ones. We conclude that affix-stripping is insufficient to account for masked morphological priming effects across languages, but that language-particular properties (in the case of Japanese, the writing system) affect the processing of (morphologically) complex words.},

  abstract  = {In a masked morphological priming experiment, we compared the processing of derived and inflected morphologically complex Turkish words in heritage speakers of Turkish living in Berlin and in native speakers of Turkish raised and living in Turkey. The results show significant derivational and inflectional priming effects of a similar magnitude in the heritage group and the control group. For both participant groups, semantic and orthographic control conditions indicate that these priming effects are genuinely morphological in nature, and cannot be due to semantic or orthographic similarity between prime and target. These results suggest that morphological processing in heritage speakers is based on the same fundamental processing mechanisms as in prototypical native speakers. We conclude that heritage speakers, despite the fact that they have acquired the language in a particular setting and were exposed to a relatively limited amount of input, can nevertheless develop native-like processing mechanisms for complex words.},

  abstract  = {The present study investigates to what extent morphological priming varies across different groups of native speakers of a language. In two masked-priming experiments, we investigate the processing of morphologically complex Turkish words in Turkish heritage speakers raised and living in Germany. Materials and experimental design were based on K\&\#305;rk\&\#305;c\&\#305; and Clahsen's (2013) study on morphological processing in Turkish native speakers and L2 learners, allowing for direct comparisons between the three groups. Experiment 1 investigated priming effects for morphologically related prime-target pairs. Heritage speakers showed a similar pattern of results as the L1 comparison group, with significant priming effects for prime-target pairs with inflected primes (e.g. 'sorar-sor' asks-ask) as well as for prime-target pairs with derived primes (e.g. 'sa\&\#287;l\&\#305;k-sa\&\#287;' health-healthy). In Experiment 2, we measured priming effects for prime-target pairs which were semantically and morphologically unrelated, but only related with regard to orthographic overlap (e.g. 'devre-dev' period-giant). Unlike both L1 speakers raised in Turkey and highly proficient L2 learners, heritage speakers also showed significant priming effects in this condition. Our results suggest that heritage speakers differ from both native speakers and L2 learners in that they rely more on (orthographic) surface form properties of the stimulus during early stages of word recognition, at the expense of morphological decomposition.},

  abstract  = {In two cross-linguistic priming experiments with native German speakers of L2 English, we investigated the role of constituent order and level of embedding in cross-linguistic structural priming. In both experiments, significant priming effects emerged only if prime and target were similar with regard to constituent order and also situated on the same level of embedding. We discuss our results on the basis of two current theoretical accounts of cross-linguistic priming, and conclude that neither an account based on combinatorial nodes nor an account assuming that constituent order is directly responsible for the priming effect can fully explain our data pattern. We suggest an account that explains cross-linguistic priming through a hierarchical tree representation. This representation is computed during processing of the prime, and can influence the formulation of a target sentence only when the structural features specified in it are grammatically correct in the target sentence.},
