    Decision-making under stress: Executive functions, analytical intelligence, somatic markers, and personality traits in young adults
    (Routledge Journals, Taylor & Francis Ltd, 2024) Yilmaz, Selin; Kafadar, Hatice
    The main goal of the study was to scrutinize mediating and moderating mechanisms identified in line with the predictions of Somatic Marker Hypothesis (SMH) and Dual Process Theory of the effect of acute stress on decision making. The sample group of the research comprised of 61 (31 females, 30 males) healthy university students aged between 18 and 23 (x = 21, SD = 1.28). Data measurement tools were Skin Conductance Response Measurement, Iowa Gambling Test, Wisconsin Card Sorting Test, Wechsler Memory Scale-III Spatial Span Subtest, Stroop Test TBAG Form, Wechsler Adult Intelligence Matrix Reasoning Subtest, Stress Rating Scale, The State-Trait Anxiety Inventory, Big Five Personality Traits Scale, Ways of Coping Inventory, Beck Depression Inventory. The findings indicated that acute stress gives rise to decision-making failures by suppressing the SCR emphasized in SMH and mental processes defined in System 2. Furthermore, neuroticism had a moderating role in the relationship between stress and decision-making. Accordingly, the abovementioned theories cannot separately be sufficient to explain decision-making under stress; but, the predictions of these theories can complement each other to thoroughly make out the physiological and cognitive mechanisms of decision-making.

    Farklı Dijital Oyun Bağımlılığı Düzeyine Sahip Çocuklarda Görsel Uzaysal Bilişsel Beceriler ve Çalışma Belleği Kapasitesinin Karşılaştırılması
    (2023) Yilmaz, Selin; Bozyiğit, Tuğba
    Amaç: Bu çalışmanın amacı 10-14 yaşları arasında video oyunları oynayan çocukların dijital oyun bağımlılığı düzeyleri ile görsel uzaysal bilişsel becerileri ve çalışma belleği performansları arasındaki ilişkiyi incelemektir. Yöntem: Araştırmanın örneklemini yaş ortalaması 12,35 (SS=0,75) olan 98 çocuk (36 kız ve 62 erkek) oluşturmaktadır. Veri toplama araçları Bilgi Toplama Formu, Çocuklar İçin Dijital Oyun Bağımlılığı Ölçeği, Saat Çizme Testi ve Wechsler Bellek Ölçeği-III Harf-Sayı Dizisi Alt Testi’dir. Bulgular: Tek Yönlü Varyans Analizi (ANOVA) sonuçlarına göre dijital oyun bağımlılığı düzeyi riskli grupta Saat Çizme Testi puanı az riski grubun puanına göre artış gösterirken, bağımlı grupta bu test performansının riskli gruba göre düşük seviyede olduğu bulunmuştur. Benzer şekilde riskli grupta Harf-Sayı Dizisi Testi puanı az riskli gruba göre artarken, bağımlı grupta bu test performansının riskli gruptan düşük seviyede olduğu saptanmıştır. Sonuç: Video oyunları oynamanın çocukların görsel uzaysal becerilerini ve çalışma belleği performanslarını artırabildiği, ancak bağımlılık arttıkça bu becerilerin bozulabileceği görülmüştür. Dolayısıyla video oyunlarının daha nitelikli ve sınırlı süreli olarak kullanılabilmesi için çocuklara yönelik eğitim programlarının oluşturulması önerilmektedir.

    Investigating the relationship between decision-making processes and cognitive processes, personality traits, and affect via the structural equation model in young adults
    (Routledge Journals, Taylor & Francis Ltd, 2020) Yilmaz, Selin; Kafadar, Hatice
    The purpose of this study was to examine the relationship between decision making and set-shifting, working memory, planning, selective attention, personality and affect, and to investigate these relations with the help of the structural equation model (SEM). A total of 100 participants, 59 female and 41 male, participated in the study. The mean age of the participants was 20.42 years (SD = 1.37). Decision making, set-shifting, selective attention, planning, working memory, personality, and affect were measured via the Iowa Gambling Test (IGT), Wisconsin Card Sorting Test, Stroop Test TBAG Version, Tower of London Test, Wechsler Memory Scale-III Letter-Number Sequencing Subtest, Basic Personality Traits Inventory (BPTI), and Positive and Negative Affect Scale (PANAS), respectively, all of which were administered individually. Results of the correlation analyses revealed that various IGT scores were correlated with the four neuropsychological tests as well as the PANAS negative-affect subscale and the BPTI openness to experience factor. Furthermore, the first SEM analysis indicated that the independent latent variables of working memory, set-shifting and planning were significant in predicting the decision making. Finally, the second model of the Block Net Scores revealed the independent latent variables of set-shifting and planning as being significant in decision-making prediction.

    Investigation the relationship between big five personality dimensions and executive functions via structural equation model
    (Istanbul Universitesi, 2018) Yilmaz, Selin; Kafadar, Hatice
    Objective: The aim of this study was to clarify the link between five factor personality traits and executive functions. Method: A total of 100 healthy participants, 59 female and 41 male, participated in the study. The data was analyzed performing Pearson moment correlation coefficients and Structural Equation Model (SEM). Results: Three models were constituted and the first model revealed a significant relationship between personality characteristics and executive functions. The second and the third models indicated that personality-executive functions relations are based on the correlation between openness to experience and shifting executive function measured by Wisconsin Card Sorting Test (WCST). Results indicated that there is a significant positive relationship between openness to experience and WCST perseverative scores. In addition, there was no correlation between openness to experience and fluid intelligence. Conclusion: According to the results of this study, it can be suggested that high openness may be characterized by high perseverative thinking rather than intellect. © 2018, Istanbul Universitesi.

    The Relationship Between Emotional Intelligence and Decision-Making
    (Istanbul Universitesi, 2023) Yilmaz, Selin
    It is noteworthy that individuals mostly make intuitive and quick choices in complex situations. It is also well established that affective processes play an essential role in decision-making under uncertainty and risk. The recent literature has focused on the contribution of emotional intelligence domains to individuals’ effective decision-making skills. The current review study aimed to draw attention to neuropsychological studies investigating a possible link between emotional intelligence and decision-making performance in clinical and nonclinical samples. In addition, decision-making and emotional intelligence were discussed within the framework of the somatic marker hypothesis and dual process theory. This review also explored the brain regions associated with decision-making and emotional intelligence, as well as the impact of emotional intelligence training programs on decision-making performance. In line with the literature, it can be concluded that an individual’s ability to make effective decisions can be enhanced through increasing emotional intelligence skill training program. © 2023, Istanbul Universitesi.
