    Master Thesis
    The Moderating Role of Ostracism and Feeling of Competence in Game-Play on the Relationship between Violent Video Game Playing and Aggression: A Longitudinal Study
    (2022) Yassı, Benan Ayazoğlu; Alper, Sinan
    Violent video games have been a subject of concern for leading to real-life violence and aggression since the violent video game industry started to gain immense popularity. These concerns can be meaningful considering General Aggression Model (Anderson, & Bushman, 2002) and Social Learning Theory (Bandura, 1977), which both suggest that aggression can be learned and imitated by being exposed to it, which can be parallel with playing violent video games and therefore being exposed to violence. The majority of the previous studies supported those theories and concerns. However, some other studies suggested that the alleged positive relationship between violent video gaming and aggression can be biased or exaggerated. According to some models and studies, the exaggeration could be due to some factors like the feeling of competence in the games and ostracism of the participants since they can be potential moderators for the relationship between violent video gaming and aggression. However, the literature on this topic is insufficient to reach conclusions due to the lack of long-term and pre-registered studies that help avoid bias. Therefore, the current study aimed to investigate, with a pre-registered approach, whether the increase in hours spent playing violent video games and aggression through time will be related; and whether the increase in the feeling of competence in games and ostracism would moderate this relationship. The current longitudinal study consisted of three measurements performed within six-week intervals, which measured participants' violent video gaming hours, non-violent video gaming hours, aggression scores, ostracism scores and the scores of their feeling of competence in the games they have played. Two hundred sixty-five people participated in this study, mostly male college students between 18-25 years old. The current study's results revealed no relationship between the increase in hours of violent video gaming and the increase in aggression over time. Also, the increase in the feeling of competence in games and the increase in ostracism over time did not moderate this relationship. Though, the only factor related to the increase in aggression was the increase in ostracism. Finally, the potential interpretation of the results, contributions and limitations of the study, and guidelines for future research were discussed.

    Güven ve şüphe: Bilgi kaynaklarının güvenirliği komplo teorilerine olan inancı nasıl şekillendiriyor?
    (2025) Yener, Ceyhun; Alper, Sinan
    Bu tez, bireysel bilgi kaynaklarının (örneğin bilim insanları ve gazeteciler) algılanan güvenilirliğinin, komplo teorilerine olan inancı etkileyip etkilemediğini araştırmaktadır. Önceki araştırmalar genellikle kurumsal güvensizlik üzerine odaklanırken, bu çalışma kamuoyunda görünür bireylerin geçmişteki doğruluklarının, onların daha sonra dile getirdiği komplo iddialarının inandırıcılığı üzerindeki etkisine odaklanmaktadır. Türkiye, Birleşik Krallık ve Amerika Birleşik Devletleri'nde yürütülen üç ön kayıtlı deneysel çalışmada (toplam N = 909), katılımcılara bilgi kaynağının önceki iddialarının doğrulandığı (güven artırıcı) veya çürütüldüğü (güven azaltıcı) kurgu senaryolar sunulmuştur. Sonuçlar, bilgi kaynağı güvenilir olarak sunulduğunda katılımcıların komplo teorisine inanma olasılığının arttığını; güvenilirlik azaldığında ise bu inancın azaldığını göstermiştir. Üçüncü çalışmada kullanılan ön test/son test tasarımı, zaman içindeki inanç değişimini de doğrulamıştır. Bireysel düşünme tarzlarına ilişkin yapılan keşifsel analizlerde (ör. açık veya kapalı fikirli düşünme), anlamlı bir etkileşim gözlemlenmemiştir.

    Inferring political and religious attitudes from composite faces perceived to be related to the dark triad personality traits
    (Elsevier Ltd, 2021) Sinan Alper; Fatih Bayrak; Onurcan Yilmaz; Alper, Sinan; Yilmaz, Onurcan; Bayrak, Fatih
    We used composite face images perceived to have different levels of Dark Triad personality traits (narcissism psychopathy and Machiavellianism) and asked participants to predict these target individuals' religious and political identities. In Study 1 (N = 550) Turkish participants rated faces with higher levels of perceived Dark Triad traits as less likely to be religious to believe in God and more likely to be left-winger and to vote for a left-leaning party in all categories except for male narcissism. In a pre-registered follow-up study (N = 1001) we recruited a nationally representative US sample and replicated the same results with minor differences regarding male and female narcissism and voting preferences. Participants' own political and ideological identities and their stereotypical evaluation of the target groups were mostly ineffective in explaining their predictions. The results suggest that people can perceive faces with higher levels of Dark Triad traits as less religious and less conservative. © 2021 Elsevier B.V. All rights reserved.

    Multidimensional intuitive–analytic thinking style and its relation to moral concerns epistemically suspect beliefs and ideology
    (Society for Judgment and Decision making, 2023) Fatih Bayrak; Burak Doǧruyol; Sinan Alper; Onurcan Yilmaz; Dogruyol, Burak; Alper, Sinan; Yilmaz, Onurcan; Bayrak, Fatih
    Literature highlights the distinction between intuitive and analytic thinking as a prominent cognitive style distinction leading to the proposal of various theories within the framework of the dual process model. However it remains unclear whether individuals differ in their thinking styles along a single dimension from intuitive to analytic or if other dimensions are at play. Moreover the presence of numerous thinking style measures employing different terminology but conceptually overlapping leads to confusion. To address these complexities Newton et al. suggested the idea that individuals vary across multiple dimensions of intuitive–analytic thinking styles and distinguished thinking styles between 4 distinct types: Actively open-minded thinking close-minded thinking preference for effortful thinking and preference for intuitive thinking. They proposed a new measure for this 4-factor disposition The 4-Component Thinking Styles Questionnaire (4-CTSQ) to comprehensively capture the psychological outcomes related to thinking styles, however no independent test exists. In the current pre-registered studies we test the validity of 4-CTSQ for the first time beyond the original study and examine the association of the proposed measure with various factors including morality conspiracy beliefs paranormal and religious beliefs vaccine hesitancy and ideology in an underrepresented culture Türkiye. We found that the correlated 4-factor model of 4-CTSQ is an appropriate measure to capture individual differences based on cognitive style. The results endorse the notion that cognitive style differences are characterized by distinct structures rather than being confined to two ends of a single continuum. © 2024 Elsevier B.V.

    Wittgenstein’ın Psikoloji Bilimine Dair Görüşlerine Eleştirel Bir Bakış
    (2019) Sinan ALPER; Onurcan Yılmaz; Fatih Bayrak; Alper, Sinan; Yılmaz, Onurcan; Bayrak, Fatih
    Wittgenstein 20. yüzyılın ilk yarısında Tractatus Logico-Philosophicus adlı yapıtında felsefeninöldüğünü ve felsefede bugüne kadar sorulmuş tüm soruların çözümünü bulduğunu iddia etmiştir.Daha sonraları dünyayı dolaşmış ve özellikle zamanını Kierkegaard ve Nietzsche okuyarakgeçirdikten sonra erken dönemlerinde savunduğu düşüncelerini değiştirmiş ve hem dilfelsefesinde hem de bilim felsefesinde paradigmatik bir değişikliğin ilk zeminini ortayakoymuştur. Sosyal bilimlerin genelinde olduğu gibi psikoloji de bu değişimlerden veWittgenstein’ın felsefesinden paradigmatik düzeyde etkilenmiştir. Bu yazıda genel olarakWittgenstein’ın felsefesinin psikolojiyle ve bugünün sosyal psikolojisiyle olan ilişkisi eleştirelolarak incelenmiştir. Özel olarak ise Wittgenstein’ın felsefesinin eleştirel psikoloji akımınınortaya çıkmasına ve ana akım psikolojideki bağlamdan kopuk birey odaklı yaklaşımlarınirdelenmesine katkı sunduğunu savunuyoruz. Bu argümanı savunmak için ilk olarak psikolojininve özel olarak sosyal psikolojinin kısa bir tarihi verilecektir. Daha sonrasında erken dönem ve geçdönem olarak ayırdığımız iki farklı Wittgenstein portresi anlatılacak ve son olarakWittgenstein’ın çalışmalarının psikolojik çalışmalara olan etkisi tartışılacaktır.

    The five-factor model of the moral foundations theory is stable across WEIRD and non-WEIRD cultures
    (PERGAMON-ELSEVIER SCIENCE LTD, 2019) Burak Dogruyol; Sinan Alper; Onurcan Yilmaz; Dogruyol, Burak; Alper, Sinan; Yilmaz, Onurcan
    Although numerous models attempted to explain the nature of moral judgment moral foundations theory (MFT) led to a paradigmatic change in this field by proposing pluralist moralities (care fairness loyalty authority sanctity). The five-factor structure of MFT is thought to be universal and rooted in the evolutionary past but the evidence is scarce regarding the stability of this five-factor structure across diverse cultures. We tested this universality argument in a cross-cultural dataset of 30 diverse societies spanning the WEIRD (Western educated industrialized rich democratic) and non-WEIRD cultures by testing measurement invariance of the short-form of the moral foundations questionnaire. The results supported the original conceptualization that there are at least five diverse moralities although loadings of items differ across WEIRD and non-WEIRD cultures. In other words the current research shows for the first time that the five-factor structure of MFT is stable in the WEIRD and non-WEIRD cultures.

    The evil eye effect: vertical pupils are perceived as more threatening
    (Routledge info@tandf.co.uk, 2019) Sinan Alper; Elif Öykü Us; Dicle Rojda Tasman; Alper, Sinan; Tasman, Dicle Rojda; Us, Elif Oyku
    Popular culture has many examples of evil characters having vertically pupilled eyes. Humans have a long evolutionary history of rivalry with snakes and their visual systems were evolved to rapidly detect snakes and snake-related cues. Considering such evolutionary background we hypothesised that humans would perceive vertical pupils which are characteristics of ambush predators including some of the snakes as threatening. In seven studies (aggregate N = 1458) conducted on samples from American and Turkish samples we found that vertical pupils are perceived as more threatening on both explicit (Study 1) and implicit level (Studies 2–7) and they are associated with physical rather than social threat (Study 4). Findings provided partial support regarding our hypothesis about the relevance of snake detection processes: Snake phobia and not spider phobia was found to be related to perceiving vertical pupils as threatening (Study 5) however an experimental manipulation of saliency of snakes rendered no significant effect (Study 6) and a comparison of fears of snakes alligators and cats did not support our prediction (Study 7). We discuss the potential implications and limitations of these novel findings. © 2019 Elsevier B.V. All rights reserved.

    Psychological correlates of COVID-19 conspiracy beliefs and preventive measures: Evidence from Turkey
    (SPRINGER, 2021) Sinan Alper; Fatih Bayrak; Onurcan Yilmaz; Alper, Sinan; Yilmaz, Onurcan; Bayrak, Fatih
    COVID-19 pandemic has led to popular conspiracy theories regarding its origins and widespread concern over the level of compliance with preventive measures. In the current preregistered research we recruited 1088 Turkish participants and investigated (a) individual differences associated with COVID-19 conspiracy beliefs, (2) whether such conspiracy beliefs are related to the level of preventive measures, and (3) other individual differences that might be related to the preventive measures. Higher faith in intuition uncertainty avoidance impulsivity generic conspiracy beliefs religiosity and right-wing ideology and a lower level of cognitive reflection were associated with a higher level of belief in COVID-19 conspiracy theories. There was no association between COVID-19 conspiracy beliefs and preventive measures while perceived risk was positively and impulsivity negatively correlated with preventive measures. We discuss the implications and directions for future research.

    Yüzlere Atanan Cinsiyet Etiketlerinin Cinsel Çekicilik Algısı Üzerindeki Etkisi
    (2021) Sinan Alper; Erdal Kozan; Alper, Sinan; Kozan, Erdal
    Bu çalışma yüzlere atanan cinsiyet etiketlerinin yüzlerin çekiciliklerini nasıl etkilediğine odaklanan iki ayrı deneysel çalışmadan oluşmaktadır. Çalışma 1’de 278 (%68) kadın 129 (%32) erkek olmak üzere toplam 407 katılımcı yer almıştır. Katılımcılara 30 adet cinsiyeti belirsiz yüz fotoğrafı gösterilmiştir. Çalışma 2’de ise 151 (%54) kadın ve 131 (%46) erkek olmak üzere toplam 282 katılımcı yer almıştır. Erkek katılımcılara 30 adet %75 oranında feminen hale getirilmiş yüz fotoğrafı gösterilirken kadın katılımcılara ise %75 oranında maskülen hale getirilmiş yüz fotoğrafı gösterilmiştir. Her iki çalışmada da katılımcıların bir kısmına fotoğrafların erkeklere ait olduğu bir kısmına ise kadınlara ait olduğu bilgisi verilmiştir ve fotoğraflarla ilgili cinsel çekicilik algısını değerlendiren sorulara cevap vermeleri istenmiştir. Katılımcıların cevaplarının görmüş oldukları fotoğrafın cinsiyet etiketine göre farklılaşıp farklılaşmadığı Kruskal-Wallis H testi ile analiz edilmiştir. Elde edilen sonuçlar çekicilik algısının sadece fiziksel özelliklere göre değil fiziksel özelliklerin ait olduğu bedenin cinsiyet etiketine göre de değiştiğini göstermektedir. Bulgular evrimsel sosyal inşacı yaklaşımlar ile cinsel akışkanlık kavramı etrafında tartışılmıştır.

    COVID-19 tehdidinin siyasi lider tercihleri üzerindeki etkisi: Sağ yönelimli ve sol yönelimli kişilerin tercihleri arasındaki farklılıklar
    (2021) Elcil, Tuğçenaz; Alper, Sinan
    Unexpected and threatening situations that remind people of their mortality and lead to an increase in existential concerns such as terrorist attacks, infectious diseases, or an experimentally manipulated threat perception have been found to be effective on various social and political attitudes and behaviors. Several studies showed that such situations also have an effect on political leader preferences, mediated by perceived personality characteristics of political leaders. Moreover, political leader preferences of people with different political orientations may differ depending on the perceived personality characteristics of political leaders. The current research has two main aims: (1) To investigate how the existential concerns due to COVID-19 affects political candidate preferences based on the personality characteristics of candidates (whether warm or competent); (2) To investigate whether political orientation predicts the difference between voting intentions for warm and competent political candidates. An experimental study with 687 Turkish participants was conducted. Participants were randomly assigned to mortality salience condition or control condition, and political candidate characteristics were manipulated as one of the candidates has warm-related characteristics and the other has competent-related characteristics. It was found that COVID-19 related mortality salience manipulation had no effect on political candidate preferences, while the personality of political candidate had a significant effect on the political candidate preferences. Specifically, results showed that political candidate that has competent-related personality characteristics was more likely to be preferred by participants. Also, it was found that political orientation did not predict the difference between the voting intentions for warm and competent political candidates, and this finding was discussed in light of the worldview defense hypothesis of Terror Management Theory and conservative shift hypothesis. It was shown that both of the left-oriented and right-oriented participants were more likely to prefer the political candidate who had competent-related personality characteristics, compared to the political candidate with warm-related characteristics. The possible explanations of these findings, limitations of the present study and suggestions for future studies were discussed.
