© Springer Nature Switzerland AG 2020.Gaze has a major role in social interaction. As a deictic reference, gaze aims at attracting visual attention of a communication partner to a referred entity in the environment. Gaze direction in natural faces is a well-investigated domain of research at behavioral and neurophysiological levels. However, our knowledge about deictic role of gaze in Human Robot Interaction is limited. The present study focuses on a comparative analysis of the deictic role of gaze direction in alternative face morphologies. We report an experimental study that investigated deictic gaze in a virtual reality environment. Human participants identified object locations by utilizing deictic gaze cues provided by avatar faces, as well as natural human faces. Our findings reveal a facilitating role in the accuracy of objection detection in favor of gaze embedded in natural faces compared to gaze embedded in synthetic avatar face morphologies.


The Role of emotions and emotion regulation in the system justification process
Solak, Nevin; Sümer, Nebi; Jost, John T.; Department of Psychology (2015)
The studies of emotions and emotion regulation from the social psychological perspective have been dominated by two general approaches, namely, individual and group-based research perspectives (e.g., Frijda, 1986; Gross, 2014; Halperin, 2014; Smith, Seger, & Mackie, 2007). Considering that emotions cannot only be limited to the individual- and the group-level contexts, the system-level dynamics (Stangor & Jost, 1997) should be examined to better understand their impacts on both individual and society. Drawi...

Mısır, Selin; Demir, Ayhan Gürbüz (Wiley, 2020-08-01)
© 2019 International Union of Psychological ScienceThe purpose of this study is to examine the reported level of self-disclosure in online communication and understand the relationship between perceived interpersonal competence and self-disclosure in an online context, taking into account the moderating role of shyness. The study sample consists of university students (N = 585). Hierarchical multiple linear regression analyses revealed that, controlling for participants' online media use, shyness moderated ...

Several studies show that stress reduces Functional Cerebral Asymmetries (FCA) in different species. Since only few studies have evaluated the effect of stress on FCA in dogs, a clear conclusion about the possible impact of stress and FCA has not yet been achieved in dogs. This is what we aim to achieve by using different motor laterality tests. Paw preferences of two groups of dogs (n=27), including chronically stressed and normal ones, were tested within the groups by food reaching (FR) and KongTMtests co...
The Relationship between mindfulness and resilience among adolescents: mediating role of self-compassion and difficulties in emotion regulation
Aydın Sünbül, Zeynep; Güneri, Oya; Department of Educational Sciences (2016)
The aim of the present study was to test a proposed model for the relationship between mindfulness and resilience as mediated by self-compassion and difficulties in emotion regulation among socio-economically disadvantaged adolescents. A total of 752 students (426 female, 326 male) between 14-19 age ranges (M = 15.82, SD=.88) participated in the study. The Demographic Information Form, 14-Item Resilience Scale (RS-14) (Wagnild, 2010; Terzi, 2006 for RS-25 Item), Mindful Attention and Awareness Scale-A (MAAS...

Tanglay, Özgün; Erzen, Jale Adile; Department of History of Architecture (2007)
This study aims to analyze how industrial design as a profession and discipline has been presented to the public in Turkey. The object of the study is constituted by the popular home style magazines which increased rapidly in number through the dynamics of the post-1980 period. These publications have been inspected in the scope of the research and their in constructing and shaping public awareness about design culture has been the focus of the study. The main theme of the thesis is focused on the analysis ...
