The growing interdisciplinary research field of psycholinguistics is in constant need of new and up-to-date tools which will allow researchers to answer complex questions, but also expand on languages other than English, which dominates the field. One type of such tools are picture datasets which provide naming norms for everyday objects. However, existing databases tend to be small in terms of the number of items they include, and have also been normed in a limited number of languages, despite the recent boom in multilingualism research. In this paper we present the Multilingual Picture (Multipic) database, containing naming norms and familiarity scores for 500 coloured pictures, in thirty-two languages or language varieties from around the world. The data was validated with standard methods that have been used for existing picture datasets. This is the first dataset to provide naming norms, and translation equivalents, for such a variety of languages; as such, it will be of particular value to psycholinguists and other interested researchers. The dataset has been made freely available.

Tekrarlama Krizi' bazen, çalışmaların tekrarlanabilmesinden kaynaklı bir soruna işaret ediyor gibi algılanabilir. Ancak metinde kriz sözcüğü, 'bir şeyin çok az bulunması durumu (bkz. https://sozluk.gov.tr/) anlamına gelmektedir. Dolayısıyla, 'tekrarlama krizi' tekrarlama durumunun nadir olarak görüldüğü bir duruma karşılık gelmektedir.

Cognate facilitation and false cognate inhibition effects have been tested in various language pairs with different experimental tasks and participant profiles so far. However, studies focusing on the recognition or production of (false) cognates are nearly absent for Turkish-English despite the prevalence of these words. Thus, using a backward lexical translation task (from L2 to L1), this study aimed to investigate whether cognate facilitation and false cognate inhibition effects could be observed in Turkish-English by testing 50 adult Turkish L2 speakers of English. The materials were made up of cognates, false cognates, and controls. The effect of L2 proficiency was also manipulated by dividing the participants into two proficiency groups (high vs. low) based on OPT scores. Also, the role of morphology was introduced by using mismatch items (polymorphemic in L2 but monomorphemic in L1). The findings showed a robust cognate facilitation and false cognate inhibition but no significant effect of L2 proficiency. The role of morphology was not conclusive and came with its limitations. These results provided supporting evidence for the language non-selective view and pointed towards the presence of these effects irrespective of language, task or participant profile. Also, a compelling need for measuring proficiency using multiple measures emerged.

Studies investigating the morphological processing of affixed forms have to date focused predominantly on inflectional rather than derivational forms and have mostly tested L1 speakers. The present study investigated how high and low proficiency Turkish learners of L2 English generalize regular/irregular verbal inflection and deadjectival un-/inderivatives to novel stems in an acceptability judgment task. The results showed that the participants generalized both the inflectional and derivational affixes to novel stems when these stems were similar to the existing stems appearing together with these affixes. However, the participants showed no preference when novel stems were dissimilar both in the case of verbal inflection and deadjectival derivatives. The proficiency level of the participants did not affect the overall response patterns. The results are discussed in terms of different models proposed for the morphological processing of complex word forms.
