    Uyku İğcikleri ve Klinik Yansımaları
    (Türkiye Klinikler, 2021) Torun Yazıhan, Nakşidil
    Uyku çalışmalarında yapılan ölçümler iki temel düzeyde yürütülmektedir. Uykunun süre, yüzde, latans, uyanıklık, etkinlik gibi özelliklerini içeren makro düzey ve her bir döneme özgü kaydedilen beyin osilasyonlarına ilişkin sıklık, süre, latans, yoğunluk, güç gibi özelliklerini içeren mikro düzey. Bu alanda yapılan araştırmalar bize, uyku ile ilişkili farklı düzeylerdeki bu değişkenlerin beyin yapı ve işlevleri ile ilişkisi hakkında bilgi vermektedir. Uykuya ilişkin değişkenlerde gözlenen anormallikler ise, çeşitli psikopatolojilerin gelişim mekanizmaları hakkında bize yeni bilgiler sunmakta, bazı bozukluklar için biyolojik gösterge olarak düşünülüp incelenmekte, bunların tedavileri için yeni yaklaşımlar ortaya koymak amacıyla mercek altına yatırılmaktadır. Son yıllarda üzerinde durulan, uykunun mikrograf elemanlarından bir tanesi olan uyku iğcikleri bu bağlamda ümit vaat etmektedir. Bu yazıda, uyku iğciklerinin özellikleri ve işlevleri çeşitli boyutlarıyla anlatılarak hangi bozukluklarda değişikliğe uğradığı, hangilerinde biyolojik gösterge olarak önerildiği tartışılmaktadır. Makalede, ayrıca, uyku iğciği aktivitesinin otizm açılımı kapsamında bozukluk (OAKB), Alzheimer hastalığı, şizofreni, travma sonrası stres bozukluğu (TSSB) ve insomniadaki elektrofizyolojik değişimleri hakkında bilgi verilmektedir.

    Are Teens at Risk? An Overview of Social Media Addiction among Adolescents
    (2021) Demircioğlu, Zeynep Işıl; Göncü Köse, Aslı
    Belongingness and interpersonal communication are among the most essential human needs. However, the ways individuals satisfy these needs change with the advances in technology. Especially with the increase of internet usage, social media platforms became the primary source that satisfies these needs of individuals. However, despite of its contribution to social communication, recent research also revealed the negative consequences of social media use, especially those of social media addiction. Social media addiction (SMA) is defined as possessing a high motivation or inner tendency to use social media to an extent that it leads to dysfunctional outcomes such as failure in work/academic performance, decline in psychological well-being, or breakdown in social relationships. As an initial step for prevention programs, identifying the antecedents and the protective factors for SMA is as important as revealing its consequences. In the present chapter, characteristics of SMA, along with antecedents and consequences of SMA among adolescents are summarized. Furthermore, future directions for SMA research, practical implications and intervention strategies indicated in the literature to prevent SMA among adolescents are presented.

    Attention mediates the effect of emotional arousal on learning outcomes in multimedia learning: an eye-tracking study
    (2023) Genç Aksaray, Sevgi; Özçelik, Erol
    Recent findings from psychological studies have shown that emotional arousal improves human memory. However, more evidence is necessary if these results are generalisable to multimedia learning environments. Considering these needs, the study has the goal to examine the effect of emotional arousal on multimedia learning. Fifty-seven participants were presented with instructional materials with either high- or low-arousing words and pictures in an experimental study. The eye movements of participants were recorded while they studied the instructional materials to examine the online processes during learning. The results suggest that emotional arousal enhanced recall and transfer scores. The eye-tracking results demonstrate that emotional arousal attracted attention. The results of the mediation analysis suggest that fixation time on emotional pictures as an indicator of attention mediated the relationship between emotional arousal and learning outcomes. The findings show the importance of the guidance of attention by emotional multimedia elements for learning.

    The effect of agitation on caregivers’ burden in patients with dementia
    (2014) Özel Kizil, Erguvan Tuğba; Altintafi, H. Özge; Bafituğ, Gülbahar; Durmaz, Nazli; Altunöz, Umut
    Introduction: The purpose of this study was to examine the effect of agitation on caregiver relatives’ subjective burden together with other possible factors such as depressive symptoms, cognitive functions, duration of dementia, and caregivers’ age, education and gender. Materials and Method: The participants were 49 patients with dementia (mean age: 76.5; SD: 5.6) and their caregivers. Standardized Mini Mental Test and Cornell Scale for Depression in Dementia were administered to the patient. Cohen-Mansfield Agitation Inventory, Informant Questionnaire of Cognitive Decline in the Elderly and Zarit Burden Scale were administered to the ca-regivers. Linear regression analysis was used to examine the effects of the variables on caregiver burden. Results: There was neither a significant difference between gender and type of caregiver in terms of Zarit Burden Scale points, nor a significant correlation between Zarit Burden Scale scores and Standardized Mini Mental Test, Cornell Scale for Depression in Dementia, age and education of the patient, education of the caregiver or duration of dementia. Significant correlations between Zarit Burden Scale scores and caregivers’ age, Informant Questionnaire of Cognitive Decline in the Elderly and Cohen-Mansfield Agitation Inventory scores were found. Linear regression analysis showed a relationship only between agitation and caregiver burden. Conclusion: Patients’ agitation frequency which was assessed by Cohen-Mansfield Agitation Inventory was the basic factor in determining subjective caregiving. In addition to psychopharma-cological treatment, psychosocial interventions for caregivers are effective. In our country, dayca-re and homecare services, as well as supportive and educative psychosocial programs including interventions for agitation, should be improved.

    Relationship of internet gaming disorder severity with symptoms of anxiety, depression, alexithymia, and aggression among university students
    (Yerküre Tanıtım & Yayıncılık Hizmetleri, 2019) Evren, Cüneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay
    Objective: 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.
