Numerous studies in psychology, cognitive neuroscience and psycholinguistics have used pictures of objects as stimulus materials. Currently, authors engaged in cross-linguistic work or wishing to run parallel studies at multiple sites where different languages are spoken must rely on rather small sets of black-and-white or colored line drawings. These sets are increasingly experienced as being too limited. Therefore, we constructed a new set of 750 colored pictures of concrete concepts. This set, MultiPic, constitutes a new valuable tool for cognitive scientists investigating language, visual perception, memory and/or attention in monolingual or multilingual populations. Importantly, the MultiPic databank has been normed in six different European languages (British English, Spanish, French, Dutch, Italian and German). All stimuli and norms are freely available at http://www.bcbl.eu/databases/multipic .

This study investigated whether form and meaning relatedness modulate the processing of morphologically related German verbs. In two overt visual priming experiments, we compared responses for verb targets (kommen, come) that were preceded by a purely semantically related verb (nahen, approach), by a morphologically and semantically related verb (mitkommen, come along), by a purely morphologically related verb (umkommen, perish), or by an unrelated verb (schaden, harm). In Experiment 1, morphological relatedness produced robust facilitation, which was not influenced by semantic relatedness. Moreover, this morphological facilitation was far stronger than the priming by purely semantically related verbs. In Experiment 2, orthographically similar primes (kämmen, comb) produced interference effects and thus indicated that the morphological facilitation effects were not the result of sheer form overlap between primes and targets. These findings argue for a single system that processes morphological relations independently of form and meaning relatedness.

This study investigated whether German participles are retrieved as whole words from lexical storage or whether they are accessed via their morphemic constituents. German participle formation is of particular interest, since it is concatenative for both regular and irregular verbs and results from combinations of regular/irregular stems with regular/irregular suffixes. Data from visual priming showed that regular and irregular participles facilitated their base verbs to the same degree, which argues against different processing systems. Furthermore, ''illegal combinations'' of participle affixes and verbal or nonverbal stems (geworft, gewurft) were as effective as correct participles (geworfen) in facilitating the morphologically related base verb (werfen). This indicates that stems contained in illegal combinations were accessed, regardless of whether they originated from regular or irregular verbs. These findings strongly argue for a single system that processes both regular and irregular inflection via access to morphemic constituents. Such a single processing model is suggested.
