Task-irrelevant emotion distracts executive processing on the one hand and executive control suppresses emotional processing on the other. This reciprocal cognitionemotion link underlies emotion regulation, which is critical for mental health. The present dissertation investigated the intricate relationship between cognitive load and emotional distraction, using non-emotional executive control training and taking mood-related effects into account. Two groups of participants were either trained on a high-load conflict resolution task or completed a low-load simple identification task. Both groups then completed an intermediate-load conflict resolution task with (Experiment 1) and without (Experiment 2) distracters. Distracter pictures were manipulated considering both valence and arousal dimensions. During training session and subsequent experiments, participants' accuracy scores, reaction times, and pupil diameters were recorded. At the behavioral level, the results of Experiment 1 revealed impaired performance in the presence of all task-irrelevant emotional pictures irrespective of cognitive load and training paradigm. Furthermore, after adjusting for state anxiety levels, cognitive load and training interacted with emotional distraction. At the physiological level, the effects of executive training were observed exclusively for negative arousing distracters, for which executive training reduced pupillary responses. Importantly, sustained effects of training were observed in Experiment 2; training reversed the association between behavioral and physiological responses and depression and anxiety levels. Together, the findings of the present study have important implications for emotion regulation and treatment of mental disorders by demonstrating the modulation of emotional distraction and mood-related behavioral and physiological responses by single-session nonemotional executive control training.

The Effect of intranasal oxytocin on pupil dilation during trustworthiness evaluation and facial expression recognition tasks Saraçaydın, Fatma Gülhan; Gökçay, Didem; Department of Cognitive Sciences (2015) Our ability to recognize facial expressions and emotions can be modulated by both external and internal factors. One of these internal factors is the neuropeptide “oxytocin”. Many studies have highlighted the involvement of oxytocin in recognition of facial expressions and approach-related trusting behaviors. In the current study, we investigated the effects of oxytocin on recognition accuracy and trustworthiness judgements using facial expressions. We used a subset of expressions and images from the Karoli...
The Localization of emotional stroop activations in healthy and major depressive disorder populations using fMRI Başgöze, Zeynep; Gökçay, Didem; Department of Cognitive Sciences (2015) Among many tasks suggested to measure emotional conflict resolution, the Word-Face Stroop Task stands out since it specifically creates a conflict between two emotional items: Emotional words versus emotional faces. The Turkish valence-specific Word-Face Stroop Task is demonstrated to work as an effective tool to measure emotional conflict resolution and revealed different behavioral patterns between depressed and healthy groups. In this dissertation, using the functional magnetic resonance imaging (fMRI)-c...
The Impact of Caregivers' Expressed Emotion and the Patients' Perception of Expressed Emotion on the Positive and Negative Symptoms of Patients with Schizophrenia in a Sample From Turkey BAŞTUĞ, GÜLBAHAR; Karanci, Nuray (Kare Publishing, 2015-06-01) The impact of caregivers' expressed emotion and the patients' perception of expressed emotion on the positive and negative symptoms of patients with schizophrenia in a sample from Turkey
The role of meta-mood experience on the mood congruency effect in recognizing emotions from facial expressions Kavcıoğlu, Fatih Cemil; Gençöz, Tülin; Department of Psychology (2011) The aim of the current study was to investigate the roles of meta-mood experience on the mood congruency effect in recognizing emotions from neutral facial expressions. For this aim, three scales were translated and adapted to Turkish, namely Brief Mood Introspection Scale (BMIS), State Meta-Mood Scale (SMMS), and Trait Meta-Mood Scale (TMMS). The reliability and validity analyses came out to be satisfactory. For the main analyses, an experimental study was conducted. The experimental design consisted of th...
The Mediator role of emotion focused coping on the relationship between perceived stress and emotional eating Yılmaztürk, Nergis Hazal; Demir, Ayhan Gürbüz; Çelik Örücü, Müge; Department of Educational Sciences (2018) The purpose of this study was to examine the mediating role of emotion focused coping on the relationship between perceived stress and emotional eating. The sample of the study was consisted of 711 university students (461 female, 250 male). Perceived Stress Scale (PSS), Coping Styles Inventory (CSI), Three Factor Eating Questionnaire (TFEQ - R21), and demographic information form were used in order to collect data in both paper-pencil and online forms. In order to answer research question, simple mediation...
