The primary goal of this thesis was to investigate the L1 and L2 processing of morphologically complex words by making use of psycholinguistic experimental techniques. Specifically, the question to be answered in the present study was how native speakers of Turkish process morphologically complex (derivational) word forms in L1 Turkish and in L2 English. It was also aimed at investigating the potential developmental similarities and/or differences between different L2 groups at distinct proficiency levels. Using identical methodologies, the processing of transparent, frequent, and highly productive Turkish suffixes –lI (attributive affix; e.g. güçlü “powerful”) and – sIz (privative affix; güçsüz “powerless”) and English suffixes –ful (e.g. careful) and -less (e.g. careless) were examined in masked priming experiments. The findings of the experiments demonstrated similar priming effects for L1 Turkish and the high proficiency L2 English group, which could be taken as evidence for the fact that decompositional processes are at work during word recognition in native and second language morphological processing of derived words. Less proficient L2 speakers, on the other hand, revealed priming effects only for words derived with the –ful suffix. In addition, even though L1 processing and L2 processing of the high proficiency group seem to be identical, the results of an orthographic control task revealed that the L2 processing of derivational morphology is characterized by both the orthographic and the morphological properties of words, whereas L1 processing is influenced only by the morphological properties during early visual word recognition. It is therefore asserted that the L1 processing of derived words is distinct from the L2 processing of derived words to a certain extent. The observed L1-L2 distinction is discussed in terms of the quality of input that L2 speakers have been exposed to.

The Second language processing of nominal compounds: a masked priming study Çelikkol Berk, Nurten; Kırkıcı, Bilal; Department of English Language Teaching (2018) The primary purpose of the present study was to understand the workings of the cognitive mechanisms underlying L2 morphological processing, and more particularly, to explore how noun-noun compounds in L2 English are processed by native speakers of Turkish in the earliest stages of word recognition. Furthermore, the study investigated the role of constituent morphemes in the processing of compound words and examined whether or not a compound word primes its first and second constituents equally. The final pu...
Testing the interface hypothesis: L2 acquisition of English subjects and articles by Turkish learners Geydir, Ecem; Sağın Şimşek, Sultan Çiğdem; Department of English Language Teaching (2020) This thesis aims to expand the testing grounds of the Interface Hypothesis (IH) by investigating the acquisition of English subjects operating with pure syntax and article uses of (in)definiteness and genericity in English governed with external and internal interfaces respectively by L1-Turkish learners. Fifty-eight sophomore students who have been studying in the Department of Foreign Language Education of a state university in central Turkey were asked to complete a Grammaticality Judgement, a Discourse ...
Morphological processing of inflected and derived words in L1 Turkish and L2 English Şafak, Duygu Fatma; Kırkıcı, Bilal; Department of English Language Teaching (2015) The present study aims at examining how inflected and derived words are processed during the early stages of visual word recognition in a native language (L1) and in a second language (L2). A second aim of the study is to find out whether or not the semantic and surface-form properties of morphologically complex words affect early word recognition processes. Two masked priming experiments were conducted to investigate morphological processing in L1 Turkish and in L2 English. In the first experiment, 40 L1 s...
An Experimental study on acquisition of prepositions in English as a third language Çabuk, Sakine; Sağın Şimşek, Sultan Çiğdem; Gracanın Yüksek, Martına; Department of English Language Teaching (2016) This study explores the role of cross-linguistic influence in third language acquisition process by examining English adpositions. Comprehension, processing and production of English prepositions (in, on, at, behind, over, to) were examined through off-line and on-line data collection tasks to find out which of the two known languages (L1 or L2) is the major source of cross-linguistic influence on the acquisition of English (L3) adpositions given the fact that adpositions are morphologically and syntactical...
Structural priming in Turkish genitive-possessive constructions Bahadır, Gözde; Hohenberger, Annette Edeltraud; Zeyrek Bozşahin, Deniz; Department of Cognitive Sciences (2012) This study addresses the question of the mental representation and processing of language by investigating “structural priming” in Turkish Genitive-Possessive (GEN-POSS) constructions. Structural priming is the facilitating effect of having already experienced a structural form on its subsequent processing. We investigate this phenomenon on a construction pair in Turkish, which shares the same external GEN-POSS morpho-syntactic template despite having distinct grammatical categories. The structures under sc...
