Lack of bump in public events when recent events prevail
(SAGE Publications Ltd, 2023) Öner, S.; Gülgöz, S.
Reminiscence bump refers to the increased recall of events from adolescence and early adulthood. It is a robust phenomenon for personal events, while the evidence for the bump has been inconsistent for public events. The present study addressed lifespan distributions of public events in a nationally representative sample of adults (N = 1200) in Turkey. We demonstrated a robust recency effect in the temporal distribution of public event memories. When we examined the bump in the most frequently reported events, the recency effect persisted. The only exception was the bump for the military coup in 1980, a relatively more distant event among the most frequent events. Findings suggested that high-impact events in Turkey’s recent past may overshadow the past events. Inline, we discuss the role of the context and age distribution of the sample to explain the inconsistency in the evidence for the reminiscence bump in public events. © The Author(s) 2022.

Toplumsal Olaylara Dair Episodik ve Semantik Bellek Süreçlerinin Heyecanlanma Düzeyi ile İlişkisinin Yaş ve Heyecanın Ölçüm Türü Açısından İncelenmesi
(Istanbul Univ, 2020) Ece, Berivan; Öner, Sezin; Gulgoz, Sami
The major aims of the study were to investigate (1) the potential differences in arousal levels for episodic (EM) and semantic memory (SM) processes regarding public events and the comparison of these differences for different age groups, (2) the consistency of self-report versus objective measures of arousal, and (3) phenomenological characteristics of the events as function of memory type and arousal level. The sample consisted of 32 young adults whose ages ranged between 18 and 25 years (M = 20.60, SD = 2.22), 33 middle-aged adults aged between 40 and 55 years (M = 47.32, SD = 6.60), and 30 elderly people aged between 60 and 75 years (M = 69.97, SD = 6.16). Participants were asked to make a remember/know judgment for the 10 public events presented to them. They further answered event-related questions (SM) and questions regarding the context of hearing about the event (EM). Moreover, they reported their arousal level during recall and evaluated each event in terms of phenomenological characteristics such as importance, emotional intensity, and valence. Arousal level was also measured using physiological measurements with the GSR device. Based on self-reports, EM processes were associated with higher arousal levels compared to SM processes whereas the five physiological indicators of arousal displayed different patterns. Both EM and SM performance displayed an increase together with the increasing arousal levels, and young participants displayed higher levels of arousal and faster physiological responses than both middle-aged and elderly adults. When phenomenological characteristics were examined, remembered public events were rated more important, emotionally more intense and more negative than known events. Furthermore, higher arousal levels were associated with higher ratings of emotional intensity, importance and negativity. The reliability of self-reports and the critical role of applying objective measures were discussed together with the findings. Finally, some suggestions were proposed for future research on the basis of the current limitations and results.

An Online Diary Study Testing the Role of Functional and Dysfunctional Self-Licensing in Unhealthy Snacking
(Academic Press Ltd- Elsevier Science Ltd, 2023) Sezer, Berke; Oner, Sezin
In the present study, we aimed to investigate how two types of self-licensing (functional and dysfunctional selflicensing) are related to unhealthy snack consumption. Self-licensing refers to the act of using justifications before gratifications and has been associated with higher snack consumption. Previous research has found that while functional self-licensing decreases unhealthy snack consumption, dysfunctional self-licensing increases the number of calories taken from unhealthy snacks. Building upon existing evidence, we addressed functional and dysfunctional self-licensing to investigate how self-licensing behaviors are associated with daily variables (i.e., stress and sleep) and unhealthy snacking habits. Participants (N = 124) were given a battery of measures at the start of the week and asked to send their snack consumption every night for a week via an online questionnaire, along with daily stress and sleep items. The data were analyzed with Hierarchical Linear Modelling. Neither selflicensing measures nor unhealthy snacking habits predicted unhealthy snack consumption. Daily stress was associated with lower unhealthy snack consumption. However, the interaction between daily stress and functional self-licensing was significant, suggesting that on stressful days functional self-licensers consume even fewer unhealthy snacks compared to less stressful days. Functional and dysfunctional self-licensing are rather new constructs which is why examining their effects is important for further research. However, in contrast to the existing evidence, we failed to find an effect of both types of self-licensing on snack consumption, suggesting the effect depends on potential contextual or individual-specific factors. Future research using a dieting sample is warranted for a better understanding of how functional and dysfunctional self-licensing operate.
Investigating the Emotion Regulation Function of Episodic Counterfactual Thinking in an Emotional Context
(Kadir Has Üniversitesi, 2023) Kurtulmuş, Emine Şeyma Çağlar; Yaman, Sezin Öner
Çalışmanın ana amacı farklı türdeki karşı-olgusal düşüncelerin (yukarı doğru vs. aşağı doğru) negatif otobiyografik anılara ilişkin olumsuz duyguların düzenlenmesindeki etkisini araştırmaktır. Geçmiş çalışmalar, karşı-olgusal düşüncelerin olumsuz duyguları düzenlemede etkili olduğunu göstermiştir (Roese, 1997). Fakat karşı-olgusal düşünmenin duyguların düzenlenmesindeki etkililiği konusunda bazı tartışmalar vardır (Blix vd., 2016, 2018). Buna göre, çalışmamızda epizodik karşı-olgusal düşüncelerin, özellikle aşağı doğru karşı-olgusal düşüncelerin, otobiyografik bellek ile ilişkin olumsuz duyguları düzenlemede etkili olabileceğini öne sürdük. Ayrıca, pozitif duygusal bir bağlamın, bireye olumlu temsiller sağlayarak karşı-olgusal düşüncenin duygu düzenleme işlevini kolaylaştırabileceğini bekledik. Bu amaçla, ilk aşamada katılımcılar (N = 114) geçmişte yaşadıkları kişilerarası negatif anıyı hatırlayıp, bu anıyı fenomenolojik özellikler açısından değerlendirmiştir. İkinci aşamada, duygu indüksiyon amacıyla bir grup katılımcıya olumlu ruh halini artırmak için pozitif video izletilirken, diğer grup kontrol grubu olup duygu içermeyen bir video izletildi. Deneyin son aşamasında, katılımcılar ilk oturumda anlattıkları negatif anıları için daha iyi bir alternatif senaryo (yukarı doğru) ya da daha kötü bir alternatif senaryo (aşağı doğru) yazmışlardır. Katılımcılar yazmış oldukları karşı-olgusal düşüncelerinin fenomenolojik özelliklerini ve duygu-durumlarını değerlendirdiler. Tahmin edildiği üzere, pozitif video izleyen grubun ruh hallerinde iyileşme görülürken negatif anılarıyla ilişkin olumsuz duyguları azalmıştır. Ancak hipotezlerimize ters olarak, karşı-olgusal düşüncelerin yazılmasından sonra katılımcılar kendilerini daha kötü hissettiler. Bununla birlikte, keşfedici veri analizinin sonuçlarına göre, karşı-olgusal düşüncelerin türünden ziyade (yukarı doğru vs aşağı doğru), fenomenolojik özelliklerinin (duygusal yoğunluk, yeniden yaşama hissi ve görsel imgelem) duygusal deneyimleri etkilediğini bulduk. Son olarak yaptığımız regresyon analizine göre, bireylerin ilk duygu-durumları, ruminasyon seviyeleri, karşı-olgusal düşüncelerin duygu değerliliği ve bu düşünceleri yazarken hissettikleri yeniden yaşam hissinin duygusal deneyimi yordayan değişkenler olarak bulduk. Bulgular ve potansiyel açıklamaları uygun teorik çerçeveler içinde tartışılarak, bu araştırma alanına yeni perspektifler sunulmuştur. Anahtar kelimeler: epizodik karşı-olgusal düşünce, duygu regülasyonu, otobiyografik hatırlama, anı fenomenolojisi, duygudurum, ruminasyon.

Remembering Successes and Failures: Rehearsal Characteristics Influence Recollection and Distancing
(Routledge Journals Taylor & Francis Ltd, 2018) Öner, Sezin; Gulgoz, Sami
We investigated the relationship between components of rumination brooding and reflection and autobiographical remembering by testing whether voluntary and involuntary rehearsal mediated rumination-related variation in the sensory-affective and metacognitive features of memory experience. We focused on achievement and failure memories as both are goal-related events yet they represent distinct experiences in terms of valence and functionality. For failure memories brooding was associated with intense recollection and reduced psychological distance. Brooding was related to enhanced distance of achievements indicating the disruptive effects of brooding on remembering. Although reflection attenuated the recollective experience for both achievement and failure memories it brought achievement memories to a subjective closer past. Structural equation modelling demonstrated the mediating role of involuntary remembering on the pattern of remembering experience.

Otobiyografik Hatırlamada Duygu Yoğunluğu ve Duygu Değerliği
(2021) Öner, Sezin
Bu derleme çalışması duygu yoğunluğu ve duygu değerliği gibi duygu bileşenlerinin olayların erişilebilirliği ve hatırlama özellikleri çerçevesinde teorik yaklaşımlar ve ampirik bulgular ışığında değerlendirmeye odaklanmaktadır. Bu bağlamda farklı otobiyografik belleğin fenomenolojik özellikleri dışında flaş bellek, travma sonrası stres bozukluğu ve duygudurum bozuklukları ele alınmakta ve duygu bileşenlerinin etkisi davranışsal ve beyin görüntüleme çalışmaları çerçevesinde tartışılmaktadır. Literatürdeki bulgulardan yola çıkarak gelecek çalışmalar için yoğunluk ve değerlik gibi duygu bileşenlerinin otobiyografik hatırlamadaki rolünü açıklayabilecek alternatif bütüncül bir yaklaşım önerilmektedir.

Representing the Collective Past: Public Event Memories and Future Simulations in Turkey
(Routledge, 2020) Öner, Sezin; Gülgöz, Sami
Common processes involved in remembering and predicting personal and public events have led researchers to study public events as a part of autobiographical memory. In the present study, we asked for past events and future predictions and examined the temporal distribution and factors that made these salient in event representations. A sample of 1577 individuals reported six most important public events since their birth and six future events that they expected. Past events mostly came from the recent past and were negative in valence. Similarly, future predictions consisted of negative events that are expected to occur in the near past. We did not find a reminiscence bump but there was a strong recency effect. Despite being inconsistent with some literature, this supports the view that remembering the past is largely influenced by the current goals and experiences. Also, in predicting what is remembered from the past and what is expected in the future, what individuals believed others would report appeared as a robust predictor.

Investigating How Unhealthy Snacking Habits Affect Self-Licensing With an Online Daily Diary Study
(Kadir Has Üniversitesi, 2020) Sezer, Berke; Öner, Sezin
Bu çalışmanın ana amacı kendine izin vermenin iki türü olan işlevsel ve işlevsiz kendine izin vermenin sağlıksı atıştırma alışkanlığına olan değişiminin incelenmesidir. Daha önceki çalışmalarda artan atıştırmalık tüketimiyle ilişkili bulunan kendine izin verme, tatmin edici davranışlardan önce gerekçeler oluşturmaya vermek olarak tanımlanmıştır. Önceki bir çalışma işlevsel kendine izin vermenin sağlıksız atıştırmalık tüketimini düşürdüğünü bulurken, işlevsiz kendine izin vermenin yükselttiğini bulmuştur. Bu çalışmada, yeni kavramsallaştırılmış bu iki yapının bulgularını tekrarlamayı ve bu bulguların ilişkisini güçlendirebilecek ya da azaltabilecek olası düzenleyici değişkenleri incelemeyi amaçladık. Katılımcılardan (N = 131) bir hafta boyunca her gece gün içerisinde tükettikleri atıştırmalıkları yollamaları istendi. Tahmin edildiği üzere, sonuçlar işlevsiz kendine izin vermenin sağlıksız atıştırmalık tüketimini arttırdığını gösterdi. Bununla birlikte, işlevli kendine izin verme ve sağlıksız atıştırmalık tüketimi arasındaki negatif ilişkiye dair bir sonuç bulamadık. Daha fazlası, hipotez ettiğimiz düzenleyici değişken ilişkileri için de destek verici sonuçlar bulmakta başarısız olduk. Yine de, keşfedici veri analizlerimiz iki ana noktada özetleyebileceğimiz ilginç sonuçlar gösterdi: (a) sağlıksız atıştırmalık tüketme alışkanlığı ve dürtüselliği yüksek olan katılımcılar göndermiş oldukları atıştırmalıklar bireysel olarak incelendiğinde daha yüksek kalorili atıştırmalık tükettiler, (b) sağlıksız atıştırmalık alışkanlığı daha az sağlıklı atıştırmalık tüketimiyle bağlantılı bulundu. Son olarak, sonuçlarımızın kendine izin verme alanyazınına olan katkıları ve ilerde gerçekleştirilebilecek olası çalışmalar tartışıldı. The main purpose of this study is to investigate how two types of self-licensing (functional and dysfunctional self-licensing) are affected by unhealthy snacking habits in the context of snack consumption. Self-licensing, which is found to be associated with higher snack consumption, is the act of using justifications prior to gratifications. Previous research has found that while functional self-licensing decreases unhealthy snack consumption, dysfunctional self-licensing increases the amount of calories taken from unhealthy snacks. In this study, we aimed to replicate the findings of these two newly established constructs and investigate possible moderator variables that may increase or decrease the strength of these associations. Participants (N = 131) were asked to send their snack consumption every night for a week. As predicted, the results suggested that dysfunctional self-licensing predicted higher consumption of unhealthy snacks. However, we found no evidence for the negative relationship between functional self-licensing and unhealthy snack consumption. Moreover, we also failed to find supportive results for our hypothesized moderator relationships. Yet, our exploratory analyses showed interesting results that can be summarized as (a) higher unhealthy snacking habits and impulsivity predict higher caloric intake from individual snacks reported, (b) unhealthy snacking habits are associated with less healthy snack consumption. Finally, contribution of our results to the self-licensing literature and possible future studies that can be conducted are discussed.

Emotion Regulation Function of Autobiographical Remembering
(TURKISH PSYCHOLOGISTS ASSOC, 2020) Öner, Sezin; Gülgoz, Sami
In 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.
