Article Citation - Scopus: 4Working 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.Article Citation - WoS: 3Citation - Scopus: 4Demans Hastalarında Ajitasyonun Bakım Veren Yüküne Etkisi(Gunes Kitabevi Ltd Sti, 2014) Altunöz, Umut; Baştu, Gülbahar; Ozel Kızıl, Erguvan Tugba; Altıntaş, H Özge; Çelik, Nazlı Durmaz; Ozel, Erguvan Tugba; Ozel-Kizil, Erguvan Tugba; Bastug, Gulbahar; Bafituğ, Gülbahar; Altintafi, H. Özge; Durmaz, NazlGiriş: Bu çalışmanın amacı demans hastalarına bakım veren yakınlarında ajitasyonun öznelbakım veren yüküne etkisinin depresif belirtiler, bilişsel işlevler, demans süresi, bakım verenin yaşı, eğitimi, cinsiyeti gibi diğer etmenlerle birlikte araştırılmasıdır. Gereç ve Yöntem: Araştırmaya toplam 49 demans hastası (Ort. yaş: 76.5; Ss: 5.6) ve 49 bakım vereni katılmıştır. Verilerin toplanmasında, hastalara Standardize Mini Mental Test ve CornellDemansta Depresyon Ölçeği, bakım verenlere ise Cohen-Mansfield Ajitasyon Envanteri, Bilişsel Kayıp için Bilgilendiriciye Uygulanan Anket ve Zarit Bakıcı Yükü Ölçeği uygulanmıştır. Bulgular: Bakım verenin cinsiyeti ve yakınlık türü ile Zarit Bakıcı Yükü Ölçeği puanları açısından istatistiksel olarak anlamlı fark bulunmadığı gibi Standardize Mini Mental Test ve Cornell Demansta Depresyon Ölçeği puanları, bakım verenin eğitim süresi, hastanın yaşı, eğitim süresi vehastalık süresi ile de anlamlı korelasyon bulunmamıştır. Zarit Bakıcı Yükü Ölçeği ile Cohen-Mansfield Ajitasyon Envanteri puanı, bakım veren yaşı ve Bilişsel Kayıp için Bilgilendiriciye UygulananAnket puanı arasında anlamlı korelasyon saptanmıştır. Lineer regresyon analizinde ise bakıcı yükünün yalnızca ajitasyon puanı ile ilişkili olduğu bulunmuştur. Sonuç: Bu çalışmada elde edilen sonuçlar demans hastalarında Cohen-Mansfield AjitasyonEnvanteri ile değerlendirilen ajitasyon sıklığının öznel bakım veren yükünü belirleyen temel faktörolduğuna işaret etmektedir. Bakım verme işinin kolaylaştırılması için psikofarmakolojik tedavilerinyanı sıra bakım verenlere yönelik psikososyal girişimler de etkili olmaktadır. Ülkemizde ajitasyonayönelik müdahaleler içeren evde ve gündüz bakım hizmetlerinin, bakım verenlere yönelik psikososyal destek ve bilgilendirme programlarının yaygınlaştırılması gereklidir.Article Effects of Communication Competency and Self-Esteem on Gaming Addiction Symptoms(Turkish Green Crescent Soc, 2022) Topcu-bulut, Merve; Şaliş, İrem; Bulut, Merve TopcuGaming behavior has become more and more popular, but there has not been any research that considers the relationship between communication competency, self-esteem, and internet gaming addiction symptoms. The main aim of the ongoing study was to assess the associations between internet gaming addiction symp- toms, self-esteem, and dimensions of communication competency. For this purpose, data were obtained from 455 individuals (47.7% females and 52.3% males) who reported that they are involved in gaming. In this study, participants were assessed with the following scale set: Sociodemographic Form, Internet Gaming Disorder Scale-Short Form, Communicative Competence Scale, and Rosenberg Self-Esteem Scale. Analyses indicated that the internet gaming disorder total score has a significant and negative correlation with self- esteem and dimensions of communication competency. Besides these results, self-esteem and listening com- petency of dimensions of communication competency have been found as a significant predictor of internet gaming disorder total score. In the literature, there has been only finite published research analyzing the dimensions of communication competency, self-esteem, and internet gaming disorder.Article Citation - WoS: 2Citation - Scopus: 3The 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, HandeObjective: 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."Article Investigation of Factors Affecting Noise Robustness in Voice Activity Detectors(Gazi Univ, Fac Engineering Architecture, 2023) Ozaydin, SelmaIn this manuscript, some voice activity detectors (VADs) in the literature were examined in terms of factors affecting their robustness under different acoustic noise conditions and in this context, the changes in detection accuracy rates according to changing noise conditions were tested. In this scope, the effect of situations such as whether the threshold value used in the decision phase in VAD methods is fixed or adaptive, the analysis window is short or long, the use of more than one feature vector together has been evaluated and analyzed comparatively. While three of the four different VAD detectors examined in this manuscript use feature vectors within the short-term analysis window while generating the decision result, one decides according to the measurement result of long-term spectral vectors. The VAD detectors in the article have been tested using the NOIZEUS noisy speech database. Thus, the performance of the analyzed VADs has been evaluated under different acoustic conditions using an extensive database that has already taken place in the literature. During the testing of the analyzed VADs, different input noise speech signals with environmental background noises between [15-0dB] such as restaurant, car, street, or station were tested. Tests were carried out using objective test measurement methods and the detection accuracy rate of each VAD method was measured. The results showed that each method gave different endurance performance in adverse environmental conditions.Article Citation - WoS: 1Citation - Scopus: 1Direct and Indirect Relationships Between Cognitive Flexibility and Covid-19 Related Psychological Distress: the Mediating Role of Maladaptive Cognitive Emotion Regulation Strategies(Klinik Psikiyatri dergisi, 2022) Sayinta, Senanur; Kocak, Hatice Nur; Kaynak, HandeObjective: The effects of the COVID-19 pandemic are remarkable on individuals' mental health. During the COVID-19 pandemic, there is an increase in mental health problems and psychological distress in uninfected healthy people. The present study aimed to examine the mediator role of maladaptive cognitive emotion regula-tion strategies in the relationship between cognitive fle-xibility and COVID-19 related psychological distress experienced during the current pandemic. Method: The sample consisted of 351 young adults (86% female and 14% male) who were not infected with COVID-19 aged between 18 to 25 years old. Participants completed the self-report questionnaires, including the Cognitive Flexibility Inventory, Cognitive Emotion Regulation Questionnaire, and COVID-19 Related Psychological Distress Scale. Mediation analysis estimated total, indi-rect, and direct effects between cognitive flexibility and COVID-19 related psychological distress. Results: The correlation analyses showed that cognitive flexibility -control dimension was negatively associated with both COVID-19 related psychological distress and maladaptive cognitive emotion regulation strategies. Also, maladap-tive cognitive emotion regulation strategies and COVID-19 related psychological distress was found to be posi-tively correlated. In the study sample, the results of the bootstrap mediation indicated that maladaptive cogni-tive emotion regulation strategies, including self-blame, acceptance, rumination, catastrophizing, and blaming others, fully mediated the relationship between cogni-tive flexibility -control and COVID-19 related psycholog-ical distress. Discussion: Our findings would help psy-chological interventions designed for COVID-19 unin-fected healthy people who have lower-level cognitive flexibility -control dimension by highlighting the promi-nence that the fewer people use maladaptive cognitive emotion regulation strategies, the less they feel COVID-19 related psychological distress.Article Kronik hastalıklarda duygu düzenleme: Kalp ve damar sistemi hastalıkları, kanser, migren, fibromiyalji ve sedef hastalığı üzerine bir derleme(Association for Clinical Psychology Research, 2023) Tuna, EzgiDuygu düzenleme; duyguların oluşumunu, çeşidini, yoğunluğunu, zaman akışındaki yerini ve ifadesini belirlediğimiz bilinçli ve bilinçdışı süreçleri içermektedir. Yapılan çalışmalar, duygu düzenlemenin ruh sağlığı üzerindeki kritik etkisinin yanı sıra, fiziksel sağlık üzerinde de önemli etkilerinin olduğuna işaret etmektedir. Özellikle kronik hastalığı olan bireylerde duyguların nasıl düzenlendiği öz-bakım, tedaviye uyum ve stres kaynaklarıyla baş etme gibi pek çok süreci etkileyerek hem fiziksel hem de psikolojik iyilik hali için belirleyici olmaktadır. Bunun yanında duygu düzenlemeyle ilgili sorunların bazı kronik hastalıkların etiyolojisinde ve seyrinde rol oynadığına dair kanıtlar mevcuttur. Bu derleme makalesinin amacı, kronik hastalıklarda duygu ve duygu düzenlemeye dair bilimsel çalışma bulgularını özetlemek ve mevcut çalışmalardaki eksiklere değinerek gelecek çalışmalar için öneriler sunmaktır. Bu amaçla, duygular ve sağlık ilişkisine dair mekanizmaların kısaca özetlenmesinin ardından; sırasıyla, kalp ve damar sistemi (KDS) hastalıkları, kanser, migren, fibromiyalji ve sedef hastalığında duygu düzenlemeyle ilgili bulgulara değinilmiştir. Özetle, KDS hastalıklarının etiyolojisinde duygu ve duygu düzenlemenin rolüne dair kanıtların güçlü olduğu görülmekteyken, kanser için etiyolojiye dair bulguların çelişkili olduğu söylenebilir. Migren, sedef hastalığı ve fibromiyalji için ise çalışma bulguları ilişkisel niteliktedir. Genel olarak çalışmalar kronik hastalığı olanlarda olmayanlara göre duygu düzenleme sürecinde aksaklıklar olduğunu göstermektedir. Hastalar arasında işlevsel duygu düzenleme stratejilerinin daha az kullanımı; psikopatoloji belirtileri, bedensel belirtiler ve düşük yaşam kalitesi gibi olumsuz sonuçlarla ilişkilendirilmiştir. Duygu düzenleme süreçlerinin kronik hastalıklardaki rolünün anlaşılması, önleyici çalışmaların planlanması ve kronik hastalığı olan bireylerin yaşam kalitesini arttıracak müdahalelerin geliştirilmesinde rehberlik etmesi açısından önemlidir. Makale, alanyazının genel bir değerlendirmesi ve öneriler ile sona ermektedir.Article Remembered or Forgotten Stimuli: a Functional Magnetic Resonance Imaging Study on the Effects of Emotion(Kare Publ, 2020) Kilic, Betul; Ozcelik, ErolObjective: The first aim of this study is to examine why emotional events enhance memory for preceding stimuli. The second goal is to identify brain regions associated with remembering and forgetting by finding brain activation differences during encoding of remembered and forgotten stimuli. The third goal is to examine which brain areas are activated when studying emotional pictures compared to neutral ones. Method: In each trial, a picture of an object followed by an emotional or neutral picture from the Turkish culture were presented to 15 volunteers. The effect of the succeeding pictures on the remembering of preceding stimuli was examined. The participants studied the stimuli in the magnetic resonance scanner and, meanwhile, brain images were taken. The memory performances of the participants were measured with the recognition test administered one week later. Results: Behavioral results suggest that emotion has no effect on memory for preceding stimuli. Functional magnetic resonance imaging results indicate that remembered stimuli compared to forgotten ones caused more activation in left inferior frontal gyrus and left superior medial gyrus. Emotional pictures create more activation in the - mid-temporal gyrus and supramarginal gyrus compared to neutral images. Conclusion: Brain structures in which activations are observed in remembered stimuli compared to forgotten ones (left inferior frontal gyrus and left superior medial gyrus) are responsible for the semantic elaboration and associative memory formation. Thus, it can be concluded that object pictures are remembered because they are processed more deeply. Besides, activations are observed in the areas known to be related to the processing of emotional face expressions when emotional and neutral pictures are compared.Article Citation - WoS: 11Citation - Scopus: 12Relationship of Internet Gaming Disorder Severity With Symptoms of Anxiety, Depression, Alexithymia, and Aggression Among University Students(Kare Publ, 2019) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, NilayObjective: The aim of the present study was to evaluate the relationship of Internet gaming disorder severity with alexithymia and aggression among university students, while controlling for effects of anxiety and depressive symptoms. Method: The study was conducted with an online survey among 987 volunteer university students in Ankara. Participants were evaluated by administering the Toronto Alexithymia Scale (TAS-20), the Buss-Perry Aggression Questionnaire (BPAQ), the Internet Gaming Disorder Scale-Short-Form (IGDS9-SF), and the depression and anxiety subscales of the 90-Item Symptom Checklist-Revised (SCL-90-R). Results: Scores for the different scales mildly correlated with one other. In hierarchical linear regression analysis, both alexithymia (particularly the dimensions "difficulty identifying feelings" [DIF] and "externally-oriented thinking" [EOT]) and aggression (physical aggression) predicted the severity of Internet gaming disorder symptoms, together with severity of depressive symptoms. Conclusion: These findings suggest that among university students, the severity of alexithymia, particularly in its dimensions DDF and EOT, is related with the severity of Internet gaming disorder, together with aggression, particularly physical aggression, and depression.Article Travma Sonrası Stres Bozukluǧu Hastalarında Üstbilişlere İlişkin İnançlar(ANP Publishing, 2020) Yazihan, N.; Yelboǧa, Z.Objective: The concept of metacognition can be described as metacognitive structures controlling, arranging and assessing the cognitions. The aim of this study was to investigate metacognitive beliefs and their relationship with the psychological symptoms of posttrumatic stress disorder (PTSD) patients. Method: The sample consisted of 52 posttraumatic stress disorder patients (mean age=31,67±6,54) and 54 healthy participants (mean age=29,00±6,61). Metacognitive beliefs were measured through Metacognitive Questionnaire-30 which is accepted as a measuring device of metacognitive beliefs, metacognitive processes and judgment. To describe symptom profiles Symtom Checklist-90 was used. Results: Data were analyzed by using MANCOVA. PTSD group scores were significantly higher than control group for uncontrallability and danger (includes items that worry and rumination are negative, dangerous and difficult to control); need to control thoughts (includes items that some thoughts are need to be controlled and suppressed) and finally lack of "cognitive confidence" (includes items about problems related to memory and attention). On the other hand, positive beliefs about thoughts which involves the items related to the idea that worry and rumination is functional was lower among individuals with PTSD. Discussion: Trauma patients think that worry and rumination have negative consequences, and some thoughts need to be controlled and supressed as they are dangerous. The elevation of clinical symptoms such as obsession, depression and psychotic symptoms were correlated with the increase of abnormal metacognitive belifs. Thoughts are dangerous and need to be controlled, appear to be related to obsesive thoughts, anger and hostility and interpersonal sensitivity sypmtoms. © 2020 ANP Publishing. All rights reserved.
