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)-compatible Turkish Word-Face Stroop, it is aimed to show that the group differences in behavioral patterns will be reflected as different brain activation patterns. The behavioral results of this valence-specific Word-Face Stroop revealed that both group succeeded to show positive-negative asymmetry effect, i.e. slowing down towards negative cases; whereas patients were faster and more correct towards negative cases in contrast to healthy group. In line with these behavioral results, different patterns of brain activations are found between the groups: Compared to healthy group, patients showed higher activations in cognitive control centers of the brain, such as right Dorsolateral Prefrontal Cortex and Superior Frontal Gyrus towards negative stimuli; and they showed higher activations in Frontal Eye Field and Middle Frontal Gyrus that are crucial for attention regulation and reorientation, towards incongruent cases. These activations, along with the behavioral findings, lead to the conclusion that patients‘ allocation of attention is mostly biased toward negativity. Thus, rather than showing a specific emotional or cognitive deficits, patients seem to have a differently molded attentional mechanism that is negatively-biased.

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...
The effect of executive control training on emotional distraction during conflict resolution: a pupillometry study
Koç Yılmaz, Şeyma; Bozşahin, Hüseyin Cem; Department of Cognitive Sciences (2020-10-9)
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 hig...
The association of self-discrepancy with depression and anxiety: Moderator roles of emotion regulation and resilience
Gürcan Yıldırım, Derya; Gençöz, Tülin (Springer Science and Business Media LLC, 2020-03-23)
Self-discrepancy theory posits that people experience emotional vulnerabilities to specific emotions when they have discrepancies between their actual, ideal and ought selves. The purpose of the current study was to test the effect of self-discrepancies (discrepancies between actual self and ideal, ought, and undesired selves) on depression and anxiety in a Turkish population, and to examine the moderator roles of emotion regulation and resilience in the relationship between self-discrepancies and negative ...
The relationship between the dimensions of alexithymia and the intensity of depression and anxiety
Motan, Irem; Gençöz, Tülin (2007-12-01)
Objective: The aim of the present study was to underline the multidimensional nature of alexithymia, and to examine the relationship between these dimensions and the intensity of depression and anxiety symptoms.
Exploring the Link Between Emotional and Behavioral Dysregulation: A Test of the Emotional Cascade Model
Tuna, Ezgi; Bozo Özen, Özlem (Informa UK Limited, 2014-01-01)
The emotional cascade model (Selby, Anestis, & Joiner, 2008) posits that the link between emotional and behavioral dysregulation may be through emotional cascades, which are repetitive cycles of rumination and negative affect that result in an intensification of emotional distress. Dysregulated behaviors, such as non-suicidal self-injury, are used to reduce aversive emotions and distract the person from ruminative processes. The aim of the present study was to investigate the emotional cascade model in a no...
