Reading requires the assembly of cognitive processes across a wide spectrum from low-level visual perception to high-level discourse comprehension. One approach of unravelling the dynamics associated with these processes is to determine how eye movements are influenced by the characteristics of the text, in particular which features of the words within the perceptual span maximise the information intake due to foveal, spillover, parafoveal, and predictive processing. One way to test the generalisability of current proposals of such distributed processing is to examine them across different languages. For Turkish, an agglutinative language with a shallow orthography–phonology mapping, we replicate the well-known canonical main effects of frequency and predictability of the fixated word as well as effects of incoming saccade amplitude and fixation location within the word on single-fixation durations with data from 35 adults reading 120 nine-word sentences. Evidence for previously reported effects of the characteristics of neighbouring words and interactions was mixed. There was no evidence for the expected Turkish-specific morphological effect of the number of inflectional suffixes on single-fixation durations. To control for word-selection bias associated with single-fixation durations, we also tested effects on word skipping, single-fixation, and multiple-fixation cases with a base-line category logit model, assuming an increase of difficulty for an increase in the number of fixations. With this model, significant effects of word characteristics and number of inflectional suffixes of foveal word on probabilities of the number of fixations were observed, while the effects of the characteristics of neighbouring words and interactions were mixed.

Phonological mediation in reading: a theoretical framework
Özkan, Ayşegül; Acartürk, Cengiz; Kırkıcı, Bilal; Department of Cognitive Sciences (2020-10-14)
A set of perceptual and cognitive processes at various levels, from low-level visual perception to high-level discourse comprehension, underlie reading. Accordingly, research on reading focuses on different aspects of reading ranging from prelexical processing and word recognition to syntactic parsing, sentence comprehension, and discourse comprehension with various technical and theoretical tools including behavioral experiments, neuroimaging techniques, and computational models of eye movement contr...
Age and response bias: evidence from the strength-based mirror effect.
Criss, AH; Aue, W; Kılıç Özhan, Aslı (SAGE Publications, 2014-10-01)
Performance in episodic memory is determined both by accurate retrieval from memory and by decision processes. A substantial body of literature suggests slightly poorer episodic memory accuracy for older than younger adults; however, age-related changes in the decision mechanisms in memory have received much less attention. Response bias, the willingness to endorse an item as remembered, is an important decision factor that contributes to episodic memory performance, and therefore understanding age-related ...
Eye movement control in Turkish reading: a corpus-analytic approach
Beken Fikri, Figen; Acartürk, Cengiz; Department of Cognitive Sciences (2015)
In this thesis, the eye movement parameters during Turkish reading were examined in terms of the characteristics of the words. These eye movement parameters were first fixation landing position, first fixation duration, gaze duration, refixation probability and skipping probability. The text characteristics were specified by word length, launch site, word frequency, and word predictability. A corpus-analytic approach was employed in order to achieve a general picture of Turkish reading patterns. The analyse...
Learning transferability of cognitive tasks by graph generation for brain decoding
Coşkun, Bilgin; Yarman Vural, Fatoş Tunay; Department of Computer Engineering (2021-12-10)
Brain decoding involves analyzing the cognitive states of human brain by using some statistical techniques in order to understand the relations among the cognitive states, based on neuroimaging data. A very powerful tool to acquire the brain data is functional magnetic resonance images (fMRI), which generates three-dimensional brain volume at each time instant, while a subject performs a cognitive task involving social activities, emotion processing, game playing, memory etc. However, it is very difficult a...
Vocal synchrony as a coregulation indicator of attachment bonds
Harma, Mehmet; Sümer, Nebi; Hazan, Cynthia; Department of Psychology (2014)
This dissertation aims to explore the concept of coregulation in adulthood based on the analyses of vocal cues in conversations. Moderators which potentially affect vocal coordination between romantic partners were also examined. Twenty-four heterosexual dating couples (Mage = 21.25; SD = 1.03) from Cornell University were recruited for the Study-1. Participants communicated with their romantic and stranger partner in a balanced order. Their conversations were recorded and vocal features were extracted. Gra...
