Article Citation - Scopus: 2The Effect of Derogation Strategies Used by Females in Intrasexual Competition on Males' Mate Preferences(Turkish Psychologists Assoc, 2010) Dural, Seda; Karasar, Asu; Cetinkaya, Hakan; Çetinkaya, Seda DuralThis study investigated the effect of derogation strategies used by females in intrasexual competition on males' mate preferences. For this purpose, a total of four studies, one of them being a preliminary study, were conducted. In the preliminary study, a measurement tool including derogation strategies used by females in intrasexual competition was developed. The first study was conducted to examine which derogation strategies were used more frequently by females in intrasexual competition. Results showed that females used derogation strategies related to promiscuity and infidelity of their rivals more frequently than derogation strategies related to appearance of their rivals. The second study investigated the derogation strategies affecting males' decisions in mate preference. Findings showed that males were affected by derogation strategies including promiscuity and infidelity more than derogation strategies including appearance. The third study examined whether the results of the second study changed according to the relationship type (e.g., long term or short term) planned by males. The results of the multi-sample confirmatory factor analysis with mean structures indicated that there was no significant difference between long term and short term relationship groups for derogation strategies including promiscuity and infidelity. However, findings yielded a significant difference between the two groups in terms of derogation strategies including appearance; males in short term relationship group were affected by derogation strategies including appearance more than the males in long term relationship group.Article Citation - WoS: 2Hemispheric Asymmetry in Expression and Perception of Happiness(Turkish Psychologists Assoc, 2012) Gulbetekin, Evrim; Iyilikci, Osman; Amado, Sonia; Cetinkaya, Hakan; Dural, Seda; Çetinkaya, Seda DuralHemispheric asymmetries in happiness expression -which has an important role in interpersonal communication and its perception- have been studied using different techniques. However, it is not clear whether the source of the asymmetry is the poser or the observer. In Experiment I, we investigated on which hemiface (right/left) the expression of happiness was better identified. Subjects evaluated right-sided happy chimeric faces as more expressive. In Experiment II, we examined whether the source of the bias was the observer's hemispheric asymmetry or the poser's facial asymmetry. Stimuli were briefly presented unilaterally, either in the left visual field(LVF)/right hemisphere(RL) or in the right visual field(RVF)/left hemisphere(LH). Faces were recognized faster in LVF condition, but they were evaluated as more expressive in RVF condition. Right-sided happy faces were found to be more expressive in RVF condition. Results indicated LH superiority in the recognition of happy expression and a RH superiority in the duration of facial processing. Additionally findings pointed out a sex difference in subjects' evaluation time and evaluation scores. Men evaluated the stimuli faster in the RH condition than they did in the LH condition; while women evaluated the faces with higher scores in LH than they did in RH condition.Article Heteroseksüel ve Homoseksüel Aldatılmaya Verilen Tepkilerde Gözlenen Cinsiyet Farklılıklarının İncelenmesi(2014) Çeti̇nkaya, Hakan; Hünler, Olga Selin; Çetinkaya, Seda Dural; Can, Seda; Kaya, Alp GirayAmaç: Bu çalışma ile kadın ve erkeklerin, farklı aldatılma senaryolarında (homoseksüel ve heteroseksüel) yer alan sadakatsizlik biçimlerinden (cinsel ve duygusal) hangisini daha rahatsız edici buldukları ve bu durumda ortaya çıkan duygu türünün ne olduğunun (öfke, tiksinme, şaşkınlık, üzüntü ve kıskançlık) incelenmesi amaçlanmıştır. Yöntem: Çalışmada, 449 erkek ve 432 kadın olmak üzere toplam 881 katılımcı yer almıştır. Katılımcılar, heteroseksüel veya homoseksüel sadakatsizliğe ilişkin senaryoların yer aldığı iki koşuldan birine tesadüfî olarak atanmış ve sunulan senaryo temelinde, katılımcılardan duygusal ya da cinsel aldatılma durumlarından hangisinin kendilerini daha çok rahatsız edeceğini belirtmeleri istenmiştir. Buna ek olarak, katılımcılardan, seçilen sadakatsizlik türüne bağlı olarak, en fazla hissedecekleri duyguyu belirtmeleri istenmiştir. Sunulan çalışmada, kategorik değişkenler arasındaki çok yönlü etkileşimlerin incelenmesine olanak sağlayan açımlayıcı çok yönlü frekans analizi kullanılmıştır. Bu yöntemle, aldatılmaya verilen tepkilere ilişkin dört kategorik değişkenin yer aldığı, hiyerarşik logaritmik doğrusal bir model geliştirilmiştir. Sonuçlar: Çalışma bulguları, aldatılmanın üremeyle sonuçlanma olasılığına bağlı olarak kadın ve erkek katılımcıların verdikleri tepkilerin farklılaştığını göstermiştir. Tartışma: Sunulan çalışmada farklı duygusal tepkilerin de hesaba katılması ile cinsel ve duygusal sadakatsizliğe verilen duygusal tepkinin kıskançlıkla sınırlı olmadığı bulunmuş, bulgular aldatılma sonrasında ortaya çıkabilecek tepkilerin yordanmasındaki önemi açısından tartışılmıştırArticle Citation - WoS: 2Citation - Scopus: 2Testing the Concealed Ovulation Hypothesis in the Framework of Facial Symmetry Fluctuations Moderated by Menstrual Cycle in Women(Turkish Psychologists Assoc, 2010) Çeti̇nkaya, Hakan; Dural, Seda; Gulbetekin, Evrim; Çetinkaya, Seda DuralWith three studies, a long lived position that women have concealed ovulation, and its possible adaptive value were investigated. In the first study, systematic changes in women across the menstural cycle were elaborated and of those, cyclic changes in the facial symmetry in regularly ovulating women were investigated. The findings showed predictable fluctuations on females' facial symmetry throughout their menstural phases. In order to determine whether the differences among the deviation from the symmetry scores of the facial pictures obtained from four menstural phases (namely, menstural, proliferative, ovulatory, and secretory phases) were detectable by males, in the second experiment, males evaluated the facial-menstural pictures for their attractiveness. The male participants rated the pictures obtained from ovulatory phases as the most attractive of all. Also they found the pictures obtained from the menstural phases to be least attractive. In the third study, half of the male participants (familiar males) rated four menstural pictures obtained from the same females, the other half of them (unfamiliar males) rated four menstural pictures, but this time each of which obtained from different females. The males in the latter group were not able to distinguish attractiveness of the facial pictures of different females. The results indicate that although there is some extent of concealment of ovulation in women as an adaptation, it is not completely concealed, especially from the familiar (or pair-bonded) males. Thus, men might have equipped with a counter-adapt, a mental device, through their evolutionary history to cope with the problem of concealment of ovulation in women by staying with her and observing the cyclic changes on her facial attractiveness.
