The nature of the mental representation and processing of morphologically complex words has constituted one of the major points of controversy in psycholinguistic research over the past two decades. The Dual-Mechanism Model defends the necessity of two separate mechanisms for linguistic processing, an associative memory and a rule-system, which account for the processing of irregular and regular word forms, respectively. The purpose of the present study was to analyse the validity of the claims of the Dual-Mechanism Model for second language (L2) processing in order to contribute to the accumulating but so far equivocal knowledge concerning L2 processing. A second purpose of the study was to find out whether L2 proficiency could be identified as a determining factor in the processing of L2 morphology. Two experiments (a lexical decision task on the English past tense and a elicited production task on English lexical compounds) were run with 22 low-proficiency and 24 high-proficiency first language (L1) Turkish users of L2 English and with 6 L1 speakers of English. The results showed that the regular-irregular dissociation predicted by the Dual-Mechanism Model was clearly evident in the production of English lexical compounds for all three subject groups. A comparatively weaker dissociation coupled with intricate response patterns was found in the processing of the English past tense, though possibly because of a number of confounding factors that were not sufficiently controlled. In addition, direct comparisons of the L2 groups displayed a remarkable effect of L2 proficiency on L2 morphological processing.

Hidden Concepts in the History and Philosophy of Origins-of-Life Studies: a Workshop Report Mariscal, Carlos; et. al. (2019-09-01) In this review, we describe some of the central philosophical issues facing origins-of-life research and provide a targeted history of the developments that have led to the multidisciplinary field of origins-of-life studies. We outline these issues and developments to guide researchers and students from all fields. With respect to philosophy, we provide brief summaries of debates with respect to (1) definitions (or theories) of life, what life is and how research should be conducted in the absence of an acc...
CROSS-LEVEL TYPING THE LOGICAL FORM FOR OPEN-DOMAIN SEMANTIC PARSING Öztürel, İsmet Adnan; Bozşahin, Cem; Department of Cognitive Sciences (2022-8-29) This thesis presents a novel approach to assigning types to expressive Discourse Representation Structure (DRS) meaning representations. In terms of linguistic analysis, our typing methodology couples together the representation of phenomena at the same level of analysis that was traditionally considered to belong to distinctive layers. In the thesis, we claim that the realisation of sub-lexical, lexical, sentence and discourse-level phenomena (such as tense, word sense, named entity class, thematic role, a...
Signals of understanding in multilingual communication : a cross-linguistic functional-pragmatic analysis of interjections Akkuş, Mehmet; Daloğlu, Ayşegül; Department of English Language Teaching (2013) The main objective of this study is to investigate and find out the contribution of interjections as indicators of understanding in an Azerbaijani-Turkish Lingua Receptiva (LaRa) communication within the framework of Functional Pragmatics. The data utilized in this study were collected by video recording four Turkish and two university Azerbaijani native speakers who had paired each other and played a world famous guessing game Taboo. The length of data obtained from these recordings is circa two hours. The...
Multiple criteria project selection problems Çağlar, Musa; Karasakal, Esra; Department of Industrial Engineering (2009) In this study, we propose two biobjective mathematical models based on PROMETHEE V method for project selection problems. We develop an interactive approach (ib-PROMETHEE V) including data mining techniques to solve the first proposed mathematical model. For the second model, we propose NSGA-II with constraint handling method. We also develop a Preference Based Interactive Multiobjective Genetic Algorithm (IMGA) to solve the second proposed mathematical model. We test the performance of NSGA-II with constra...
Convergence of text and reader: a study of textual strategies and the formation of configurative meaning in selected works of fiction Shadi, Mehran; Sönmez, Margaret Jeanne M.; Department of English Literature (2018) In this study, first, the foundational developments in the domains of linguistics, philosophy of language and literary theory that have led to a transformation of the concept of the reader are reviewed closely. Then, to understand the nature of literary responses, an Interactionalist Model of Readership (IMR) is proposed to explore the two sides of the reader-text interaction and the nature of the final product of the reading act. Using various examples, the interaction between the text and the reader is, t...
