Publication Open Access Emotion regulation function of autobiographical remembering(Turkish Psychologists Association / Türk Psikologlar Derneği, 2020) Öner, Sezin; Department of Psychology; Gülgöz, Sami; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 49200In this study, we aimed to investigate emotion regulation function of autobiograhical remembering within an integrative perspective. We asked participants to recall sadness, anger and happiness related events for emotion induction, then they recalled any random memory that came to their mind. In the latter remembering experience. Pre- and post-report emotionality ratings and phenomenological features of the recall were examined to test whether subsequent recall served to upregulate positive emotions. Only in sadness and anger memory groups who recalled memories with high emotional impact reported more positive emotions after subsequent remembering. Also, we found distinct mechanisms by which sadness and anger groups used for emotion regulation such that for the sadness group whereas the emotional intensity accounted for the role of upregulation, for the anger group, importance of the event predicted enhanced positivity. Findings are discussed in the context of the emotion regulation function of autobiographical remembering. / Bellek ve duygusal süreçlerin ilişkisi alanyazında geniş yer tutmaktadır. Bu iki kavramı bütünsel bir bakışla incelemeyi amaçladığımız bu çalışmada otobiyografik belleğin duygu düzenleme işlevine odaklanılmıştır. Üç ayrı gruptaki katılımcılara, üzüntü, öfke veya mutluluk uyandıracak anılar hatırlatılmış ardından da bir yönerge verilmeden herhangi bir anı hatırlamaları istenmiştir. Katılımcılar ayrıca anı özelliklerini belirtmişler ve duygu düzenleme stratejilerini değerlendirmişlerdir. Hatırlamadan önce ve sonra katılımcıların nasıl hissettikleri de sorulmuştur. Bulgulara bakıldığında, duygusal etkisi yüksek anı hatırlayan olumsuz anı grubu katılımcılarının, yönergesiz hatırlama sonrasında duygu durumlarını belirgin olarak olumlulaştırdığı görülürken, bu değişimin üzüntü ve öfke gruplarında farklı anı özellikleri tarafından yürütüldüğünü saptanmıştır. Üzüntü grubunda yönergesiz anının duygusal yoğunluğunun, öfke grubunda ise anının öneminin duygu değişimine aracı olduğu gösterilmiştir. Bulgular, otobiyografik hatırlamanın duygu düzenleme işlevi bağlamında tartışılacaktır.Publication Open Access Territory establishment, song learning strategies and survival in song sparrows(Wiley, 2020) Campbell, S. Elizabeth; Darling, Saethra; Beecher, Michael D.; Department of Psychology; Akçay, Çağlar; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 272053In most songbirds, the processes of song learning and territory establishment overlap in the early life and a young bird usually winds up with songs matching those of his territorial neighbors in his first breeding season. In the present study, we examined the relationships among the timing of territory establishment, the pattern of song learning and territorial success in a sedentary population of song sparrows (Melospiza melodia). Males in this population tend to learn their songs from their neighbors and consequently they show high song sharing with neighbors and use these shared songs preferentially in interactions with them. Males also show significant variation in the timing of territory establishment, ranging from their natal summer to the next spring. Using a three-year dataset, we found that the timing of territory establishment did not systematically affect the composition of the song repertoire of the tutee: early establishers and late establishers learned equally as much from their primary tutors and had a similar number of tutors and similar repertoire sizes, nor did timing of territory establishment affect subsequent survival on territory. Therefore, the song-learning program of song sparrows seems versatile enough to lead to high song sharing even for birds that establish territories relatively late.Publication Open Access Bayesian Behavioral Systems Theory(Elsevier, 2019) Department of Psychology; Balcı, Fuat; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 51269Behavioral Systems Theory suggests that observable behavior is embedded in a hierarchy. A CS elicits behavior because, after learning, it activates a pathway through this hierarchy. Much of Timberlake's body of work on Behavioral Systems Theory focuses on the conditions that support the conditioning of these pathways. Most notably, his work shows that the identity of the CS, US, and the CS–US interval all help support conditioning of the system. Here, we use recent experiments in the interval timing literature to motivate a Bayesian implementation of Behavioral Systems Theory. There is a probability distribution over possible pathways through the hierarchy, and the one that maximizes reinforcement is elicited. This probability distribution is conditioned on background information, like the CS–US interval and the animal's motivational state. Lower level actions of the hierarchy, like tracking prey, are conditioned on higher level goals, like the general search for food. Our implementation of Behavioral Systems Theory captures the essential features of Timberlake's verbal model; it acts as a glue, integrating sensory, timing, and decision mechanisms with observed behavior.Publication Open Access Depression, but not dissociative experiences, predicts overgeneral memory: a systematic review and meta-regression analysis(Aves, 2022) Okan, A.; Erkent, M.A.; Department of Psychology; Aydın, Fatma; Şar, Vedat; Gülgöz, Sami; Eser, Hale Yapıcı; Faculty Member; Faculty Member; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; School of Medicine; N/A; 8542; 49200; 134359Background: reduced memory specificity (i.e., overgeneral memory) is a characteristic of autobiographical memories widely studied in clinical populations, and it is explained by rumination, functional avoidance, and executive dysfunction. Though the relationship of autobiographical memory specificity with mood and anxiety disorders has been shown, how it relates to dissociation is not well-established. Thus, we aimed to investigate whether dissociative experiences are related to overgeneral memory while considering concurrent depression as a possible confounding factor. Methods: we conducted a systematic review in compliance with The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines and searched PubMed and Web of Science databases using autobiograph* and dissoc* as our keywords. Results: of the 768 studies identified, 9 studies fulfilled the inclusion criteria. A meta-regression analysis was conducted to analyze the relationship between dissociative experiences and depression scores with autobiographical memory test scores. Our research revealed that depression scores, but not dissociative experiences, are significantly related to reduced memory specificity. Conclusion: while the possible overlap between dissociation and depression should be considered in the interpretation of the findings, dissociative experiences do not seem to pose vulnerability for reduced specificity of autobiographical memory. The number of studies on the topic is limited, and they do not have longitudinal follow-ups. The heterogeneous reporting of memory scores and low scores of dissociative experiences in the samples are also limitations of the existing studies.Publication Open Access Song sparrows do not discriminate between their own song and stranger song(Elsevier, 2020) Beecher, Michael D.; Department of Psychology; Akçay, Çağlar; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 272053Bird song is socially learned. During song learning, the bird's hearing its own vocalization is important for normal development of song. Whether bird's own song is represented and recognized as a special category in adult birds, however, is unclear. If birds respond differently to their own songs when these are played back to them, this would be evidence for auditory self-recognition. To test this possibility, we presented song sparrow males (Melospiza melodia) playbacks of their own songs or stranger songs and measured aggressive responses as well as type matching. We found no evidence of behavioral discrimination of bird's own song relative to the (non-matching) stranger song. These findings cast doubt on an earlier proposal that song sparrows display auditory self-recognition and support the common assumption in playback experiments that bird's own song is perceived as stranger song.
