Article Citation - WoS: 6Investigation of the Psychometric Properties of the Turkish Form of Subjective Memory Complaints Questionnaire(Gunes Kitabevi Ltd Sti, 2013) Ozel Kizil, Erguvan Tugba; Baştuğ, Gülbahar; Duman, Berker; Altintas, Ozge; Kirici, Sevinc; Bastug, Gulbahar; Baran, Zeynel; Altunoz, Umut; PsikolojiIntroduction: Amnestic type of mild cognitive impairment (MCI) is characterized by the presence of subjective memory complaints and impairment of memory tests. This study aims to investigate the validity and reliability of the Turkish Version of the Subjective Memory Complaints Questionnaire (SMCQ). Materials and Method: The study sample consisted of 45 MCI patients and 44 healthy elderly controls. The SMCQ is a 14-item, "yes-no" questionnaire which evaluates the severity of subjective memory complaints. The discriminant validity of SMCQ was evaluated by comparing the scores of the two groups. For concurrent validity, the correlations between SMCQ and two widely-used cognitive screening tests (MMSE and ADAS-Cog) were calculated. ROC analysis was performed to test the diagnostic validity. For reliability analysis, internal consistency was calculated. Results: SMCQ scores of the patients were higher than the controls. SMCQ scores of the subjects were positively correlated with ADAS-Cog and negatively correlated with MMSE scores. Cronbach's value was 0.83. ROC analysis yielded a sensitivity of 80% and a specificity of 66% (cut-off=4.5). Area under the curve was 0.843. Conclusion: SMCQ is a valid and reliable instrument that can be used for the assessment of SMC in elderly patients. However, community based studies should be carried out for suggesting SMCQ as a screening tool.Article A Review on Executive Functions and Memory Processes Associated With Feeding and Eating Disorders(Istanbul Universitesi, 2020) Çobanoğlu, F.Ö.; Kaynak, H.From the beginning of humankind, feeding has become one of the most important requirements of social adaptation and survival. Since the 20th century, research on feeding and eating disorders has tried to give some explanations of various eating behaviors, such as starving because of thoughts about being overweight or non-stop binge eating by the individual, relational, or social factors. However, they are inadequate to fully explain the psychopathological and cognitive factors underlying feeding and eating disorders. The complex behavioral pattern behind eating disorders can lead to impairments in people’s attention, memory, and metacognitive processes. Certain higher-order cognitive mechanisms such as problem solving, reasoning, and decision making are impaired in individuals suffering from eating disorders, especially anorexia nervosa, bulimia nervosa, and binge eating disorder, compared to healthy individuals. Several researches aimed to find out evidence that may recover these impairments or that may lead to preventive measures for the risk of developing eating disorders. The aim of the current study is to examine the researches on the effects of eating disorders on individuals’ executive functions and memory processes and to explore the links between eating disorders, executive functions, and memory. © 2020, Istanbul Universitesi.

Özge; Bafituğ, Gülbahar; Durmaz, Nazli; Altunöz, UmutIntroduction: 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.Conference Object Impact of information bandwidth of in-vehicle technologies on young drivers' attention maintenance performance: A Driving simulator study(Human Factors an Ergonomics Society Inc., 2017) Bıçaksız, PınarPrevious research indicates that young novice drivers' ability to maintain their attention on the forward roadway during driving is poorer than experienced drivers, leading to more frequent excessively long off-road glances that elevate the risk of crashes. This study directly manipulated information bandwidth of an in-vehicle monitor and asked young drivers to perform the number judgment task during simulated driving. Results show that the drivers produced more number of off-road glances and longer summed excess glance durations in 1.5-second threshold when the in-vehicle task imposed greater information processing demand. The crash risk estimated from the obtained summed excess glance durations is 3.2 times higher when the information processing demand was high than low using the 1.5-second threshold, and 4.3 times higher using the 2.0-second threshold. In practice, designers of in-vehicle technologies should consider information-processing demands of in-vehicle tasks that the technologies require in order to minimize the frequency of excessively long off-road glances during drivingArticle Citation - Scopus: 2Drivers’ Self-Reported Reasons of Speeding: a Turkish Driver Sample From Two Cities(Gioacchino Onorati Editore, 2019) Doğruyol, B.; Erdost, B.G.; Hoe, C.H.; Gupta, S.; Lajunen, T.; Özkan, T.; Bıçaksız, P.Speeding is an important risk factor of road traffic crashes, and identifying the factors associated with speeding is crucial for road safety. In the present study, face-to-face roadside interviews were conducted to investigate the reasons of speeding among Turkish drivers at six different data collection times in two different cities. A structured interview was administered to collect data from a total of 3317 and 1559 drivers in Ankara and Afyon cities, respectively. Results from the two cities consistently revealed that drivers’ self-reported speeding frequency was partially determined by gender and age. Also, perceiving speeding as a cause of crashes was associated with lower frequency of speeding. Finally, thinking that speed tickets are a means for increasing government income and that it would be safe to exceed the speed limit if driving “safely” was positively associated with frequency of speeding. These findings indicate the importance of norms and (biased) perceptions in speeding behavior. © 2019, Gioacchino Onorati Editore.

It is usually triggered by a fear of social performance especially when the performer is unfamiliar with the audience. Today, many software engineering activities (e.g. code inspection, peer review, daily meetings, etc.) require social gatherings where individuals need to present their work. However, novice software engineers may not be able to reduce their performance anxiety during their course of education. In this study, we propose a virtual reality approach to construct a practice environment for improving novice software engineers' pubic speaking experiences. Consequently, we examine the effects of virtual reality intervention on the public speaking experience of six novice software engineers from a computer engineering department. We designed a virtual auditorium to simulate the presentation delivery environment and findings suggest that using this infrastructure for training purposes can reduce presenter anxiety levels - which is consistent with related published studies. We believe that this virtual auditorium environment can deliver benefits for students and practitioners alike in terms of addressing the anxiety that is often associated with early stage career presenters.Article Citation - WoS: 12Internet Gaming Disorder and Treatment Approaches: a Systematic Review(Turkish Green Crescent Soc, 2018) Nazligul, Merve Denizci; Bas, Samet; Akyuz, Zeynep; Yorulmaz, OrcunThe purpose of this systematic review is to investigate the phenomenology of the psychiatric diagnosis of Internet Gaming Disorder (IGD), which has a serious potential, through the physical and psychosocial impacts of recent candidates for its diagnosis, followed by current treatment approaches for this problem. Using specific terms, a comprehensive database search of PsychINFO, ScienceDirect, Wiley Online Library, Web of Science, and PubMed was conducted to access particular studies that examine treatment interventions for IGD. All searches have been limited to full text papers published between 2000 and 2017. Six eligible treatment studies fulfilling the criteria of preferred reporting items for systematic reviews and meta-analyses (PRISMA) as an international guideline were included in the literature review. The evaluation criteria of the IGD were observed to differ among studies and the current samples to consist predominantly of males in adolescence to young adulthood. The findings on interventions indicate that different treatment modalities show successful results in reducing IGD symptoms and the time spent playing games, as well as on addictive individuals' progress regarding verbal expression. The general impressions of this systematic review are that although technology seems to facilitate life, Internet use and gaming habits at the same time can easily turn into a serious psychiatric problem. On the other hand, relatively little is known about IGD with a rather limited number of studies describing, assessing, and treating this problem. However, increasing information about this disorder is crucial for developing specific interventions. Thus, conducting additional research in Turkey as well as the world is essential for understanding IGD's nature and how to treat it.
