    Working Memory Functions in Autism Spectrum Disorder: a Review
    (Association for Clinical Psychology Research, 2021) Çağlar, E.; Kaynak, H.
    Autism spectrum disorder, one of the most common neurodevelopmental disorders, is a lifelong condition, especially with difficulties in social communication, limited interest, and repetitive behavior. Working memory, as a basic executive function, is a cognitive process also associated with impulse control, inhibition, organization, mental flexibility, focusing on one's attention, planning, responding to new situations, initiating and monitoring actions, problem solving, and goal-directed behaviors. Studies suggest that working memory impairments are associated with repetitive behaviors, and the risk for academic failure observed in autism spectrum disorder, and other neurodevelopmental disorders. From this point of view, working memory deficits are often found in neurodevelopmental disorders, especially in autism spectrum disorder. In the current study, following an introduction to autism and working memory, working memory functions associated with autism spectrum disorder were reviewed in detail. In this context, brain imaging studies highlighting the importance of frontal lobe functions, links between repetitive behaviors and working memory, and age differences in working memory functions were summarized. Next, working memory deficits in other neurodevelopmental disorders, such as attention defi-cit/hyperactivity disorder and pervasive developmental disorder were discussed in comparison with autism. Finally, the conclusion part of the current review tried to provide a contribution to future studies. © 2021 Association of Clinical Psychology Research.

    Relations Among Emotional Mood State Personality Dimensions and Social Desirability in Older Adults
    (Gunes Kitabevi Ltd Sti, 2018) Kaynak, Hande
    Introduction: Previous studies have shown that older adults report higher levels of positive affect (PA). Studies in the context of the five-factor model of personality have also noted the age-related changes in personality. However, the possible influence of personality on emotional state needs further investigation in older adulthood. This study examines relations among personality traits, social desirability, and positive/negative affectivity in conjunction with aging. Materials and Method: A total of 123 volunteers (62 young and 61 older adults) was participated in the study. A cross-design was used with consecutive sampling. All participants had higher education. Participants completed the Positive and Negative Affect Schedule as a measure of emotional state. Thereafter, they rated the degree to which each item described themselves on the Five-Factor Personality Inventory, which measures personality dimensions and social desirability. Results: Independent t-tests were conducted to compare young and older adults in terms of affectivity and personality. Findings revealed that older adults reported less negative affect (NA) compared with young adults. Older adults scored higher on agreeableness, conscientiousness, and social desirability, whereas young adults scored higher on extraversion and neuroticism. Based on correlational results, neuroticism was negatively correlated with extraversion, social desirability, and PA in older adults. Analyses of variance showed that conscientiousness, neuroticism, and social desirability impacted positive/negative affectivity. Conclusion: The results indicated that neuroticism proved to be the most important factor on emotional well-being. Older adults low on neuroticism experienced less NA. Furthermore, conscientiousness and social desirability had strong effects on PA indicating that the age-related differences found in affectivity might not only be attributable to age-related changes in personality, but also partly attributable to age-related increases in social desirability.

    Losing the Life: A Review on Autobiographical Memory in Alzheimer’s Disease
    (2021) Cengil, Betül Beyza; Kaynak, Hande; Aydın, Öykü
    Alzheimer hastalığı, progresif ve nörodejeneratif bir beyin hastalığı olup yaşlı yetişkinler arasında en yaygın görülen demans tipidir. Alzheimer hastalığı, diğer demans tiplerinin aksine progresif bellek bozulmaları ile karakterizedir. Alzheimer hastalığında görülen bellek bozulmalarından biri olan otobiyografik bellek ise kişinin yaşamı boyunca meydana gelen olayların depolandığı bellek olarak tanımlanır. Alzheimer hastalığında otobiyografik bellek süreçlerinde gözlemlenen düşüşün bir sonucu, geçmiş dönemden ziyade, yakın dönem otobiyografik anıların geri getirilmesinde yaşanan zorluktur. Hem olaysal hem de anlamsal bileşenleri içeren bu bellek tipi, kişinin benlik kavramı için de önemlidir. Bu çalışmanın amacı, Alzheimer hastalarında otobiyografik bellek süreçlerinin güncel alan yazında nasıl ele alındığını incelemektir. Derlemenin giriş kısmında Alzheimer hastalığı ve hastalık ile ilişkilendirilen bilişsel süreçler, otobiyografik bellek performansının benlik için önemiyle birlikte detaylı olarak sunulmuştur. Derlemenin ikinci kısmında Alzheimer hastalarında otobiyografik bellek bozulmaları tartışılmış ve otobiyografik belleğe etki eden duygu ve koku duyusu gibi faktörlerden ilgili nöral yapılar ile birlikte bahsedilmiştir. Bu bağlamda sırasıyla duygusal boyutun (örneğin, değerlik) otobiyografik anıların oluşumu ve geri getirilmesi üzerindeki etkisi tartışılmış ve otobiyografik belleğin koku uyaranlarıyla nasıl çalışıldığı ele alınmıştır. Otobiyografik bellek ve duygu arasındaki ilişki üzerine yapılan çalışmalar, Alzheimer hastalığında otobiyografik anıların içeriğinin olumluya doğru kaydığını, bu kapsamda Alzheimer hastalarının daha olumlu otobiyografik anılarını hatırladıklarını göstermiştir. Ek olarak, koku uyaranlarının sözel ve görsel uyaranlardan daha fazla otobiyografik anı üretmeye neden olduğu bulunmuştur. Mevcut derlemenin sonuç kısmı, gelecek çalışmalara yön verebilecek bazı önerilere ayrılmıştır. Örneğin, Alzheimer hastalığının farklı evrelerinde otobiyografik belleğin incelenmesi ve bellek performansının ilgili değişkenler açısından karşılaştırılması, Alzheimer hastalığında otobiyografik belleğin doğası hakkında ayrıntılı bulgular sağlamanın yollarından biri olabilir.

    Your Need for Cognition, Cognitive Flexibility, and Cognitive Emotion Regulation Strategies Matter! the Path Beyond a Satisfied Life
    (Routledge Journals, Taylor & Francis Ltd, 2024) Kaynak, Hande; Nazligul, Merve Denizci; Cengil, Betul Beyza; Denizci Nazlıgül, Merve
    This study explored the associations among cognitive flexibility, cognitive emotion regulation (CER) strategies, need for cognition, and life satisfaction, which represents a cognitive component of subjective well-being. Previous studies have shown the importance of adaptive CER strategies for well-being, while maladaptive strategies have been linked to negative outcomes such as psychological distress, depression, and anxiety. Additionally, the need for cognition has been associated with cognitive flexibility and positive outcomes in various domains. However, the specific roles of cognitive flexibility and CER strategies in the relationship between need for cognition and life satisfaction remain relatively unexplored in the existing literature. This study aimed to address this gap by investigating how cognitive flexibility and different CER strategies contribute to the relationship between need for cognition and life satisfaction in a non-clinical sample of 239 adults via a survey consisting of a demographic information form, need for cognition scale, cognitive flexibility inventory, cognitive emotion regulation questionnaire, and satisfaction with life scale. The results demonstrated that when individuals with a high need for cognition had cognitive flexibility, they were more likely to use adaptive cognitive emotion regulation strategies, resulting in elevated life satisfaction. The findings of this study may provide insights into the underlying mechanisms that influence individuals' cognitive processes, cognitive emotional regulation, and overall life satisfaction. Such understanding can have implications for interventions aimed at enhancing cognitive flexibility, promoting adaptive CER strategies, and ultimately fostering improved life satisfaction.

    Zekâ, Örtük Bellek Performansıyla İlişkili Midir?: Yaşın Etkisi
    (2019) Kaynak, Hande
    Bu araştırmada, genel zekâ ve örtük bellek performansı arasındaki ilişki yaşlanmayla birlikte incelenmektir. Araştırmanın verileri 49 genç, 46 yaşlı olmak üzere toplam 95 gönüllü yetişkinden toplanmıştır. Genel zekâ puanı, Raven Standart Progresif Matrisler (RSPM) testi kullanılarak ölçülmüştür. Katılımcıların bellek performansını ölçmek için, Kelime Kökü Tamamlama (KKT) görevi kullanılmıştır. Örtük bellek görevinde, katılımcılardan kendilerine ilk üç harfi sunulan kelime köklerini akıllarına gelen ilk kelimeye tamamlamaları istenmiştir. Ayrıca, örtük bellek performansıyla karşılaştırma yapabilmek ve örtük ve açık bellek arasındaki ayrımı belgelemek için açık bellek performansı da ölçülmüştür. Örtük ve açık bellek performansını ayrı ayrı ölçmek için aynı KKT görevi kullanılmış, ancak bu görev farklı yönergeler altında uygulanmıştır. Faktöriyel varyans analizi (ANOVA) bulgularına göre, yaşın genel zekâ puanları üzerindeki temel etkisi istatistiksel olarak anlamlı bulunmuştur. Pearson momentler çarpımı korelasyon hesaplamaları sonucunda, ilerleyen yaşla birlikte RSPM testinden alınan toplam doğru puanın azaldığı, testi tamamlama süresinin ise arttığı görülmüştür. Örtük KKT görevi puanları ile RSPM testi toplam doğru puanları arasındaki ilişki ve açık KKT görevi puanları ile RSPM testi toplam doğru puanları arasındaki ilişki de istatistiksel olarak anlamlı bulunmuş, aralarındaki ilişkilerin pozitif olduğu kaydedilmiştir. Buna karşın, örtük KKT görevi puanı ile RSPM testi tamamlama süresi ve açık KKT görevi puanı ile RSPM testi tamamlama süresi arasındaki ilişki istatistiksel olarak anlamlı değildir. Mevcut çalışma bulguları, örtük KKT görevi ölçümünün genel zekâyla olan güçlü ilişkisini göstermektedir. Çalışma, bu kapsamda, özellikle yaşlı nüfusta, geleneksel açık bellek ölçümlerinin gölgesinde kalan örtük bellek ölçümünün genel zekâya olan katkısına dikkat çekmesi açısından önemlidir.

    The Mediating Role of Cognitive Flexibility in the Relationship Between Metacognition and Psychological Health: a Study in a Non-Clinical Sample
    (Kare Publ, 2021) Aydin, Oyku; Kaynak, Hande
    Objective: Metacognition is a concept that refers to the awareness and control of individuals' cognitive processes. In this regard, metacognitive processes may promote cognitive flexibility. The present study investigates the impact of metacognitions on adults' psychological health and the mediating role of cognitive flexibility through bootstrap analysis. Method: The sample comprised of 212 university students. All volunteers had no history of psychiatric/neurological disorders and no use of medication affecting the central nervous system for the last six months. Participants were required to complete the Metacognitions Questionnaire-30, the General Health Questionnaire- 12, and the Cognitive Flexibility Inventory via an online survey. Results: According to the correlation analyses, cognitive flexibility was found to be negatively correlated with dysfunctional metacognition (r=-0.227, p<0.01) and poor psychological health (r=-0.397, p<0.01); dysfunctional metacognition was positively correlated with poor psychological health (r=0.399, p<0.01). We conducted mediation analyses via the bootstrapping method using a 95% confidence interval and 5000 bootstrap samples. The results showed that cognitive flexibility had a significant partial mediating role in the relationship between metacognition and psychological health [R-2=0.26, F(2, 209)=36.38, p<0.001]. Conclusion: The findings highlighted the importance of cognitive flexibility as an underlying mechanism through the relationship between metacognition and psychological health in a non-clinical sample. The results suggested the need to take "cognitive health" into account while attempting to promote "psychological health."

    Örtük Bellekte Duygu Yükü Üzerine Bir Derleme: Depresyon ve Duygudurum Tutarlılığının Etkileri
    (2023) Cengil, Betül Beyza; Cengil, Betül Beyza; Aydın, Öykü; Kaynak, Hande
    Mevcut çalışma, önceden maruz kalınan bilginin bilinçdışı hatırlanmasını ifade eden örtük belleğe odaklanmaktadır. Duygu yükünün örtük bellek üzerindeki etkilerini incelemekte olup, özellikle depresyon ve duygudurum tutarlılığının bellek üzerindeki etkisine odaklanmaktadur. İlgili çalışmaların kapsamlı bir gözden geçirilmesi aracılığıyla, bu içsel ve dışsal faktörler ile depresyon bağlamında örtük bellek arasındaki karmaşık ilişki üzerine ışık tutmak amaçlanmaktadır. Mevcut derleme, konuyla ilgili önceki araştırmaları özetleyip değerlendirerek, literatürdeki tutarsızlıkları ve boşlukları vurgulamaktadır. Farklı türdeki örtük bellek görevlerinin rolü, açık bulaşmanın kontrolünün önemi, depresyonun bir bozukluk olarak ve depresif duygudurum olarak ayrı bir şekilde ele alınmasının gerekliliği gibi birçok faktör tartışılmaktadır. Bu çalışma, bulguları analiz ederek, önceki araştırmalarda tutarsız sonuçlara katkıda bulunan faktörleri belirlemeye, depresyonlu bireylerde örtük belleğin temel mekanizmalarına dair bilgi sunmaya çalışmaktadır. Duygu yükünün örtük bellek üzerindeki etkisini destekleyen kanıtlar olmakla birlikte, depresyon ve duygudurum tutarlılığının etkileri henüz netlik kazanmamış ve daha fazla araştırmaya ihtiyaç duyulmaktadır. İçsel ve dışsal faktörleri inceleyerek, bu çalışma depresyon bağlamında duygular, duygudurum ve örtük bellek arasındaki ilişkinin daha iyi anlaşılmasına katkıda bulunmayı ve depresyonla ilişkili bellek bozuklukları yaşayan bireyler için gelecekteki müdahaleler ve tedavi yaklaşımlarına yol göstermeyi amaçlamaktadır.

    The Effects of Physiological Stress on Learning Instructional Materials
    (Editura Univ Oradea, 2022) Tuncol, Aleyna Su; Cengil, Betul Beyza; Aydin, Oyku; Kaynak, Hande; Ozcelik, Erol
    Psychophysiological studies have shown that stress can both enhance and impair learning. However, there is not enough research on the effects of stress on learning ecologically valid materials. Considering this need, the goal of the current study is to examine the effects of physiological stress on learning instructional materials. Thirty-eight healthy participants held their hands in either ice-cold water (cold pressor stress group) or warm water (control group) for three minutes after studying the instructional material. Learning was assessed by recall and recognition tests given on the following day. The results showed that physiological stress impaired recall but did not affect recognition, suggesting that extreme stress levels had a detrimental effect on learning tests that rely on self-initiated cues.

    Locus of Control as a Mediator of the Relationships Between Motivational Systems and Trait Anxiety
    (Sage Publications inc, 2024) Turan, Aysu; Demir, Yagmur; Kaynak, Hande
    The Reinforcement Sensitivity Theory, first proposed by Gray and later revised, describes three motivational systems: Behavioral Inhibition System (BIS), Behavioral Activation System (BAS), and Fight-Flight-Freeze System (FFFS). Studies have shown that high BIS and FFFS activation are positively related to anxiety symptoms, yet the relationship between BAS and anxiety remains unclear. Research data have also suggested that anxiety symptoms occur with the loss of perceived control. Thus, although studies on the direct effect of locus of control (LOC) on trait anxiety have accumulated for many years, the issue of how LOC may mediate the relationship between BIS/BAS/FFFS sensitivity and anxiety has not been addressed. This study aimed to explore the mediating role of LOC orientation on trait anxiety among young adults in association with these three motivational systems. Cross-sectional data were obtained from 422 volunteers. The BIS/BAS Scale, Trait Anxiety Inventory, and Rotter's Internal-External LOC Scale were applied. A series of mediation analyses were performed to estimate total, indirect, and direct effects. The results showed that BIS and FFFS positively predicted trait anxiety. In addition, LOC positively predicted trait anxiety and BIS. The results of the mediation analyses indicated that LOC functioned as a partial mediator between BIS and trait anxiety. This finding revealed that a high BIS level, one of the motivational systems, was associated with external LOC, which in turn contributed to reporting high trait anxiety in young adults. Hence, BIS and external LOC orientation could be suggested as risk factors for trait anxiety. As the external LOC orientation of individuals with high punishment sensitivity increased, their trait anxiety levels also increased. Therefore, it was suggested that it might be useful to be aware that LOC orientations of individuals with BIS sensitivity may pose a risk for trait anxiety.
