Psycholinguistic databases are reliable and practical sources for research purposes, since they provide standardized stimuli for scientific studies. The objective of the present thesis is to initiate a Turkish psycholinguistic database. Three variables are included in addition to quantitative variables (number of letters etc.): frequency, age-ofacquisition (AoA), and imageability. Frequency values are extracted from two sources; a child literature corpus (CLC) that is created for the purposes of the current thesis, and a web based corpus that represents adult language use (BOUN Corpus). Imageability ratings are collected from adult population with a questionnaire. The main research in the thesis is to compare two methods to obtain AoA values: to collect rated AoA with a questionnaire conducted on adult population, and to compare frequencies from adult and child language corpora. First, the frequency counts from CLC are compared to child speech frequencies. They seem to be correlated; therefore CLC is found to be a suitable source for acquisition data. Afterwards, frequency counts from CLC are compared to BOUN Corpus frequencies to obtain AoA data. The frequency values from both corpora, AoA values obtained from questionnaire, and imageability values are put together for the purpose of creating the Turkish psycholinguistic database.

A philosophical analysis of computational modeling in cognitive science Ürgen, Burcu Ayşen; Bağçe, Samet; Department of Cognitive Sciences (2007) This study analyses the methodology of computational cognitive modeling as one of the ways of conducting research in cognitive science. The aim of the study is to provide an understanding of the place of computational cognitive models in understanding human cognition. Considering the vast number of computational cognitive models which have been just given to account for some cognitive phenomenon by solely simulating some experimental study and fitting to empirical data, a practice-oriented approach is adopt...
A Corpus-based analysis of genre-specific discourse of research in the phd theses and research articles in international relations Küçükoğlu, Ece Selva; Enginarlar, Hüsnü; Department of English Language Teaching (2016) This study aims to investigate the genre-specific features of the introduction parts of the PhD theses (PhDTs) and research articles (RAs) in International Relations (IR). The study examines the followings: the use of lexicogrammatical features, the move step structure to find out the fitness of the CARS Model (Swales, 2004), and the rhetorical features of the two corpora. In this regard, a mixed methods research was designed to answer the research questions. Two corpora were utilized: the introduction part...
A framework for automatic information quality ranking of diabetes websites Saglam, Rahime Belen; Taşkaya Temizel, Tuğba (2015-01-01) Objective: When searching for particular medical information on the internet the challenge lies in distinguishing the websites that are relevant to the topic, and contain accurate information. In this article, we propose a framework that automatically identifies and ranks diabetes websites according to their relevance and information quality based on the website content.
Development of Metacognitive Skills Inventory for Internet Search (MSIIS): Exploratory and Confirmatory Factor Analyses Şendurur, Emine; Yıldırım, Zahide (Ilkogretim Online, 2018-01-01) This study reports the development of metacognition inventory for Internet search for middle school students. In this study, analysis and results of both exploratory and confirmatory factors are reported. Firstly, 37-items were generated considering literature review and metacognitive challenges faced during the search process, and pilot exploratory factor analysis was conducted. Secondly, the final version of the scale was distributed to 273 seventh grade students, and the existing constructs were extracte...
A Research Methodology to Conduct Effective Research Syntheses ÜSTÜN, ULAŞ; Eryılmaz, Ali (2014-01-01) The need for comprehensive and systematic research syntheses has been increasing as the number of primary studies has proliferated in educational sciences in recent years. That is the main reason why diverse applications of meta-analysis, which is one of the most effective ways of research synthesis, has been encouraged in many disciplines including social and educational sciences. The main purpose of this article is to provide a conceptual framework for meta-analysis by questioning its criticisms and stren...
