Perceived haptic softness of materials has been studied as a single dimension; however, it has recently been shown that it has multiple dimensions. Research on bimodal perception demonstrated the effect of sound frequency on perceived shapes, where people associate higher frequency sounds with angular shapes and lower frequency sounds with round shapes, known as the Bouba/Kiki effect. In this thesis the effects of onomatopoeic words, the words that mimic the sound they describe (e.g., şırıl şırıl, çatır çutur, etc.), were investigated on perceived material softness to test whether similar associations between onomatopoeic words and perceived softness also exist. Experiments were carried out using the onomatopoeic words in the written and the spoken form, and the materials in the video form. The two experiments using written and spoken onomatopoeic words report four softness related dimensions. The online experiment using written onomatopoeic words and material videos showed no significant results for the interaction effect of onomatopoeic words and materials. However, using spoken onomatopoeic words, the interaction effect was found to be significant for most of the pairings. Experiment with written onomatopoeic words conducted in a laboratory environment showed significant results for the effects of onomatopoeic words on perceived softness. There was no significant difference observed between the written and spoken modalities of onomatopoeic words, except for the main adjective Gelatinous. Hence, the obtained results are in line with previously reported findings, and support the hypothesis that onomatopoeic words have an effect on the perceived softness of materials.

The Role of Prior Knowledge and Visual Cues on Perceived Softness
KILIÇ, Fatma; Dövencioğlu, Nahide Dicle; Department of Psychology (2023-2-06)
Haptic perception is the active exploration of materials by touch. When exploring objects, we use stereotypical hand movements called ‘Exploratory Procedures’ (EPs, Lederman & Klatzky, 1987). These EPs are related to the specific material and task properties, such as rubbing a jersey to assess its softness. Softness of a material has been treated as a single dimension and in fact identified with compliance (Lederman & Klatzky, 1987; Baumgartner, 2013; Di Luca, 2016). However, it has recently been shown that...
The Effect of Labeled/Unlabeled Prior Information for Masseter Segmentation
Tabar, Yousef Rezaei; Ulusoy, İlkay (Hindawi Limited, 2013-01-01)
Several segmentation methods are implemented and applied to segment the facial masseter tissue from magnetic resonance images. The common idea for all methods is to take advantage of prior information from different MR images belonging to different individuals in segmentation of a test MR image. Standard atlas-based segmentation methods and probabilistic segmentation methods based on Markov random field use labeled prior information. In this study, a new approach is also proposed where unlabeled prior infor...
The role of synchronization of neural structures on neuron dynamics Nöral yapilarda senkronizasyonun hücre dinamikleri üzerine etkisi
Karabacak, Ozkan; Elibol, Rahmi; Şengör, Neslihan Serap (2014-01-01)
Due to the measurement techniques developed, it is now possible to observe signals at different levels in neural structures. These observations give rise to increasing works dealing with setting up the relation between such signals and cognitive processes, neurodegenerative diseases and neurobehavioral disorders. Computational neuroscience is becoming more influential in investigating the mechanisms underlining these signals. Especially oscillations in different neural structures and the role of these oscil...
The role of pore structure in sound absorption performance of lime based plasters
Meric Nursal, Işın; Tavukçuoğlu, Ayşe; Çalışkan, Mehmet (The Institute of Noise Control Engineering of the USA, Inc.; 2015-08-09)
Sound absorption performance is directly related to the pore structure of materials. The effect of materials' pore characteristics on sound absorption performance has been examined in detail, especially for materials like mineral wool, foamed metals, porous concrete, sand and soils. However, there is scarcity of knowledge in literature on relationships between sound absorption characteristics of lime-based plasters used as finishing layer(s) in buildings and their pore structure. In this study sets of lime-...
The spin effects on electronic, optical and mechanical properties of new ferromagnetic chalcopyrite: YMnS2
Yıldız, Buğra; Erkisi, Aytac; Sürücü, Gökhan (2022-05-15)
In this study, magnetic and electronic nature, optical behavior, and elasticity properties of YMnS2 compound have been investigated by using density functional theory (DFT). The compound belongs to the chalcopyrite family having tetragonal crystal structure with 122 (I-42d) space group. Firstly, the optimization process has been done for ferromagnetic, antiferromagnetic, and paramagnetic orders to find most stable magnetic order and the formation energies have been determined. Negative formation energies pr...
