Recognition memory - a type of episodic memory in long term memory - is known in the literature to be affected by emotion, aging and the modality of the presented stimuli. The major aim of this study was to investigate whether emotional stimuli enhances recognition memory. Another goal was to observe whether modality and aging effects are present and differentiable in a non-Western subject sample. In literature, emotion studies were based on mainly two dimensions of emotions: valence and arousal. However, the contribution of these two dimensions to the enhancement of recognition memory still needs clarification. The present study investigated specifically the effect of valence on recognition memory. Moreover, the experimental manipulations of this study allowed observing the effect of valence on recognition memory due to normal aging. Since modality of the presented stimuli is a major confounding factor on recognition, separate experiments involving visual and verbal stimuli were designed. Pictures and words were selected on the basis of valence and arousal ratings. The stimulus set of the visual recognition memory task consisted of the pictures selected from the International Affective Picture System (IAPS) (Lang et al., 2005). The stimulus set of the verbal recognition memory task was constructed from partially standardized material for affective norms of Turkish emotional words (METU TEW), which was developed as a part of this study. METU TEW allowed selecting words with positive, neutral and negative valence while controlling arousal. The results replicated two findings reported in the literature: (1) younger adults recognized more accurately than older adults; (2) recognition memory was enhanced for visual items regardless of age and valence. Interestingly, this study revealed that recognition memory was not enhanced for emotional stimuli varying only on the valence dimension. More specifically, there was a decline in recognition memory for positive items and no change was observed for negative items, regardless of age. Further analysis also revealed that there may be differential effects of abstractness and concreteness on verbal recognition memory in aging.

Mood, Memory, and Motor Performance and the Severity of Tardive Dyskinesia Gilleard, C. J.; Vaddadi, KS (SAGE Publications, 1986-12) <jats:p> This study tested the hypothesis that the features of tardive dyskinesia were associated with motor slowing, memory impairment, and depressive apathy all of which are considered to characterize the so-called subcortical dementias. In a sample of 48 psychiatric patients all fulfilling research criteria for tardive dyskinesia and without other signs of organic illness age-independent correlations were observed between severity of orofacial dyskinesia and measures of memory, motor performance and mood...
Age and response bias: evidence from the strength-based mirror effect. Criss, AH; Aue, W; Kılıç Özhan, Aslı (SAGE Publications, 2014-10-01) Performance in episodic memory is determined both by accurate retrieval from memory and by decision processes. A substantial body of literature suggests slightly poorer episodic memory accuracy for older than younger adults; however, age-related changes in the decision mechanisms in memory have received much less attention. Response bias, the willingness to endorse an item as remembered, is an important decision factor that contributes to episodic memory performance, and therefore understanding age-related ...
Aging Slows Access to Temporal Information From Working Memory Kılıç Özhan, Aslı; Oztekin, Ilke (Oxford University Press (OUP), 2017-11-01) To evaluate the impact of aging on controlled memory search operations, we investigated the retrieval of temporal order information from working memory (WM).
Stress generation in depression: Three studies on its resilience, possible mechanism, and symptom specificity Joiner, TE; Wingate, LR; Gençöz, Tülin; Gençöz, Faruk (Guilford Publications, 2005-03-01) Three longitudinal studies examined several issues related to stress generation in depressive symptoms among undergraduates, with emphasis on mechanisms of stress generation. Study 1 replicated the stress generation effect reported in past research. Study 2 replicated Study 1's findings and, furthermore, supported the symptom specificity of stress generation to depressive versus anxious symptoms, and, perhaps most important, found that increases in hopelessness fully accounted for the stress generation find...
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...
