Antecedents of problematic social media use and cyberbullying among adolescents: attachment, the dark triad and rejection sensitivity
(Springer, 2023) Demircioglu, Zeynep Isil; Goncu-Kose, Asli; 166202
With the acceleration of internet use, problematic social media use (PSMU) is included in our lives. When looking at the antecedents of PSMU, being young has been found to be a risk factor for PSMU. In addition to the benefits of technological advances in education and training, rapid technological developments may also result in problematic behaviors, especially among children and young. Recently, possibilities brought by technology and more widespread use of technology by young people have created a new concept, namely, cyberbullying. The present study aims to examine the effects of attachment anxiety and avoidance on PSMU and cyberbullying as with the partial mediating effects of the Dark Triad personality traits, angry rejection sensitivity, and anxious rejection sensitivity among adolescents. In general, the findings supported the proposed theoretical model. The results are discussed in terms of theoretical and practical implications along with suggestions for future research.

Effects of attachment styles, dark triad, rejection sensitivity, and relationship satisfaction on social media addiction: A mediated model
(Springer, 2021) Demircioglu, Zeynep Isil; Goncu Kose, Asli; 166202
The aim of the present study is to investigate the mediating effects of attachment styles, rejection sensitivity and the Dark Triad personality traits on the links between relationship satisfaction and social media addiction. It is proposed that insecure attachment styles (i.e., preoccupied, dismissing, and fearful attachment styles), rejection sensitivity, and the Dark Triad personality traits (i.e., Machiavellianism, narcissism and psychopathy) are negatively associated with relationship satisfaction, which, in turn, is negatively related to social media addiction. The data were collected from 229 university students from 14 different universities in four different cities of Turkey. The results of the structural equation modeling analyses revealed that relationship (dis) satisfaction was a significant predictor of social media addiction; and also, it partially mediated the link of fearful attachment with social media addiction. Furthermore, the direct positive paths from fearful attachment, rejection sensitivity and psychopathy to social media addiction were significant. The findings were discussed regarding the theoretical and practical implications along with suggestions for future research.

Evaluation of the Effectiveness of a Gaze-Based Training Intervention on Latent Hazard Anticipation Skills for Young Drivers: A Driving Simulator Study
(Mdpi, 2018) Yamani, Yusuke; Bıçaksız, Pınar; Bicaksiz, Pinar; Palmer, Dakota B.; Hatfield, Nathan; Samuel, Siby; 163626; Psikoloji
A PC-based training program (Road Awareness and Perception Training or RAPT; Pradhan et al., 2009), proven effective for improving young novice drivers' hazard anticipation skills, did not fully maximize the hazard anticipation performance of young drivers despite the use of similar anticipation scenarios in both, the training and the evaluation drives. The current driving simulator experiment examined the additive effects of expert eye movement videos following RAPT training on young drivers' hazard anticipation performance compared to video-only and RAPT-only conditions. The study employed a between-subject design in which 36 young participants (aged 18-21) were equally and randomly assigned to one of three experimental conditions, were outfitted with an eye tracker and drove four unique scenarios on a driving simulator to evaluate the effect of treatment on their anticipation skills. The results indicate that the young participants that viewed the videos of expert eye movements following the completion of RAPT showed significant improvements in their hazard anticipation ability (85%) on the subsequent experimental evaluation drives compared to those young drivers who were only exposed to either the RAPT training (61%) or the Video (43%). The results further imply that videos of expert eye movements shown immediately after RAPT training may improve the drivers' anticipation skills by helping them map and integrate the spatial and tactical knowledge gained in a training program within dynamic driving environments involving latent hazards.

Fusion of smartphone sensor data for classification of daily user activities
(Springer, 2021) Sengul, Gokhan; Özçelik, Erol; Ozcelik, Erol; Misra, Sanjay; Damasevicius, Robertas; Maskeliunas, Rytis; 115500; Psikoloji
New mobile applications need to estimate user activities by using sensor data provided by smart wearable devices and deliver context-aware solutions to users living in smart environments. We propose a novel hybrid data fusion method to estimate three types of daily user activities (being in a meeting, walking, and driving with a motorized vehicle) using the accelerometer and gyroscope data acquired from a smart watch using a mobile phone. The approach is based on the matrix time series method for feature fusion, and the modified Better-than-the-Best Fusion (BB-Fus) method with a stochastic gradient descent algorithm for construction of optimal decision trees for classification. For the estimation of user activities, we adopted a statistical pattern recognition approach and used the k-Nearest Neighbor (kNN) and Support Vector Machine (SVM) classifiers. We acquired and used our own dataset of 354 min of data from 20 subjects for this study. We report a classification performance of 98.32 % for SVM and 97.42 % for kNN.

Incivility, Mobbing, and Abusive Supervision: A Tripartite Scale Development Study
(Routledge Journals, Taylor & Francis Ltd, 2024) Sumer, H. Canan; Goncu-Kose, Asli; Toker-Gultas, Yonca; Acar, F. Pinar; Karanfil, Derya; Ok, A. Basak; 166202
Using qualitative and quantitative methodologies, in three consecutive studies with employed samples, we developed measures of workplace incivility, mobbing, and abusive supervision sensitive to the nuances of a non-Western context (i.e., Turkiye). In Study 1, we first conducted 15 focus groups (N = 149), identified culture-specific and universal themes underlying the focal mistreatment types, and developed the initial scales. We then pilot-tested (N = 427) and refined the scales using exploratory factor analytic procedures. In Study 2, confirmatory factor analyses (N range = 456-524) and associations between the new scales and their widely used counterparts (N = 353) yielded evidence for the construct validity of the scales. Study 2 also involved the development of short forms of relatively long incivility and abusive supervision scales. In Study 3 (N = 482), we first examined the extent to which the three scales were operationally distinct. Second, we examined the scales' ability to predict burnout and organizational commitment. Results supported operational distinctiveness as well as the criterion-related validity of the scales. A dominance analysis revealed that the three scales had equivalent contributions in explaining the two outcome variables, further justifying their distinctiveness. We argue that the use of present scales is not necessarily restricted to the Turkish context and may prove useful more broadly in other neo-traditional contexts.

Insights From Pupil Size to Mental Workload of Surgical Residents: Feasibility of an Educational Computer-Based Surgical Simulation Environment (ECE) Considering the Hand Condition
(Sage Publications inc, 2018) Dalveren, Gonca Gokce Menekse; Özçelik, Erol; Cagiltay, Nergiz Ercil; Ozcelik, Erol; Maras, Hakan; 115500; Psikoloji
The advantage of simulation environments is that they present various insights into real situations, where experimental research opportunities are very limited-for example, in endoscopic surgery. These operations require simultaneous use of both hands. For this reason, surgical residents need to develop several motor skills, such as eye-hand coordination and left-right hand coordination. While performing these tasks, the hand condition (dominant, nondominant, both hands) creates different degrees of mental workload, which can be assessed through mental physiological measures-namely, pupil size. Studies show that pupil size grows in direct proportion to mental workload. However, in the literature, there are very limited studies exploring this workload through the pupil sizes of the surgical residents under different hand conditions. Therefore, in this study, we present a computer-based simulation of a surgical task using eye-tracking technology to better understand the influence of the hand condition on the performance of skill-based surgical tasks in a computer-based simulated environment. The results show that under the both-hand condition, the pupil size of the surgical residents is larger than the one under the dominant and nondominant hand conditions. This indicates that when the computer-simulated surgical task is performed with both hands, it is considered more difficult than in the dominant and nondominant hand conditions. In conclusion, this study shows that pupil size measurements are sufficiently feasible to estimate the mental workload of the participants while performing surgical tasks. The results of this study can be used as a guide by instructional system designers of skill-based training programs.

Mediating processes in the relationships of abusive supervision with instigated incivility, CWBs, OCBs, and multidimensional work motivation
(Springer, 2023) Onaran, Sami Okan; Goncu-Kose, Asli; 166202
We examined how abusive supervision (AS) affected instigated workplace incivility, counterproductive work behaviors (CWBs), organizational citizenship behaviors (OCBs), and multidimensional work motivations (MWMs), in line with the Job Demands-Resources Model and Social Exchange Theory. We suggested that employees' identification with their workgroup moderates the link between AS and instigated incivility toward coworkers and that organizational identification partially mediates the association of AS with CWBs and OCBs. Furthermore, we hypothesized positive correlations between AS and external regulation as well as amotivation, consistent with the Self-Determination Theory. Finally, we predicted that job-related affective well-being would fully mediate the link between AS and autonomous work motivations while only partially mediating the link between AS and amotivation. Online surveys were used to collect data from 519 white-collar workers. The data revealed that AS was linked to a higher level of incivility toward coworkers. Furthermore, it was linked to both CWBs and OCBs, both directly and indirectly through organizational identification. Organizational identification mediated the associations between AS and MWMs as well. Finally, job-related affective well-being mediated the links of AS with external regulation, amotivation, and autonomous work motivations. Theoretical and practical implications of the findings are discussed as well as suggestions for future research.

Mindfulness as a Moderator in the Relation Among Core Belief Disruption, Rumination, Posttraumatic Symptoms, and Growth
(Springer, 2021) Haspolat, Ayperi; Cirakoglu, Okan Cem
Objectives In the present study, we tested moderated mediation models where the moderator role of mindfulness and its subscales has an indirect effect of core belief disruption (CBD) on posttraumatic symptoms (PTS) and posttraumatic growth (PTG) through intrusive (IR) and deliberate (DR) ruminations. Methods Two hundred forty-six individuals, ages ranging between 19 and 77, with traumatic experiences participated in the study. The data were collected by Traumatic Experience Screening List, Core Beliefs Inventory (CBI), Impact of Event Scale-Revised Form (IES-R), Event-Related Rumination Inventory, Posttraumatic Growth Inventory (PTGI), and Five Facet Mindfulness Questionnaire (FFMQ). Results The moderator role of mindfulness was supported both for PTS and PTG. The analysis indicated that the indirect effect of CBD on PTS only through IR was moderated by mindfulness total score (MF-T) and nonreactivity (NR) subscales. The analysis revealed that the MF-T x IR interaction effect was statistically significant. The interaction effect was significant for only low and medium levels of MF-T. When the model was analyzed for PTG, it was observed that the indirect effect of CBD on PTG through IR and DR was moderated significantly only for describing (DES) subscale of mindfulness. In addition, the DES x IR interaction effect was significant only for medium and higher levels of DES. It was also observed that the DES x DR interaction effect was significant only for medium and high levels of DES. Conclusions Mindfulness and its components should be taken into consideration when assessing posttraumatic symptoms and growth.

Oral Trail Making Task as a Discriminative Tool for Different Levels of Cognitive Impairment and Normal Aging
(Oxford Univ Press, 2013) Bastug, G.; Ozel-Kizil, E. T.; Sakarya, A.; Altintas, O.; Kirici, S.; Altunoz, U.
The Trail Making Test (TMT) is a useful measure of executive dysfunction in elderly subjects. This study aims to investigate the discriminative validity of the oral version of the TMT (OTMT), which can be administered to subjects with visual or motor disabilities, in elderly patients with Mild Cognitive Impairment (MCI; n = 30), Alzheimer's disease (AD; n = 30), and healthy controls (HCs; n = 25). The WAIS-R Digit Span Backwards Subscale, written form of the Trail Making Task, the Clock Drawing Test, the AD Assessment Scale-Cognitive Subscale, and the OTMT were also administered to all participants in order to examine the concurrent validity of the OTMT. The OTMT part B discriminated between patients with MCI, AD, and HC correctly. The OTMT completion time was not correlated with age, but was negatively correlated with education. In conclusion, the OTMT (mostly part B) is a valid and practical measurement tool for different levels of cognitive impairment, especially for patients with visual or motor disabilities for whom the classical written form is not feasible.

Pain perception, distress tolerance and self-compassion in Turkish young adults with and without a history of non-suicidal self-injury
(Springer, 2021) Tuna, Ezgi; Gencoz, Tulin; 163887
Individuals with a history of non-suicidal self-injury (NSSI) tend to have altered pain perception and difficulty in regulating their emotions. Previous work on NSSI has relied heavily on retrospective self-report data and clinical Western samples. The present study explored pain perception, emotional reactivity, distress tolerance and self-compassion in a sample of non-clinical Turkish young adults with and without a history of self-injury by employing a multi-method, laboratory-based design. Participants were 70 Turkish young adults (34 with a history of NSSI and 36 controls). Pain was induced by the cold pressor test before and after a distressing card-sorting task. Skin conductance was recorded throughout the entire procedure. Measures of NSSI, emotion dysregulation and self-compassion were also administered. Although the groups were comparable in pain threshold and physiological reactivity to pain, participants with NSSI had increased pain tolerance and reported more subjective distress during the distressing task. Pain perception did not change as a function of distress and both groups were similar in physiological reactivity to distressing stimuli. Participants who self-injure reported less self-compassion and more difficulty in regulating emotions than controls. These findings illustrate that participants with a history of NSSI have altered pain perception and experience more subjective distress during a stressful task. Individuals who self-injure may benefit from interventions targeting emotion regulation and self-compassion.

Relationships of domestic violence with bullying, silencing-the-self, resilience, and self-efficacy: Moderating roles of stress-coping strategies
(Springer, 2023) Karakus, Cansu; Goncu-Kose, Asli; 166202
The present study aimed to investigate the relationships of Child Exposure to Domestic Violence (CEDV) with bullying, silencing-the-self (STS) behaviors, resilience, and self-efficacy. In addition, moderating effects of stress-coping strategies in the relationships of CEDV with the outcome variables were examined. Data were collected from 569 adolescents aged between 14 and 17. The findings showed that CEDV was positively related to bullying and STS and it was negatively associated with resilience, overall self-efficacy, academic and emotional self-efficacy. Optimistic style and seeking social support moderated the relationship between CEDV and resilience. Also, the self-confident style, seeking social support, and optimistic style moderated the associations between CEDV and self-efficacy. Findings are discussed in terms of theoretical and practical contributions as well as directions for future research.

Sleep, sleep spindles, and cognitive functions in drug-naive patients with first-episode psychosis
(Amer Acad Sleep Medicine, 2020) Yazihan, Naksidil Torun; Yetkin, Sinan; 276238
Study Objectives: Various lines of clinical findings have suggested abnormalities in macro- or microstructural parameters of sleep in patients with schizophrenia. Meanwhile findings are inconclusive due to some confounding factors, such as the heterogeneity of the disorder, drug regimen, and duration of the illness. There are a few studies in the literature that have been conducted on drug-free patients with first-episode psychosis (FEP). Based on this knowledge, we aimed to explore sleep characteristics, sleep spindles, and neuropsychological profiles of the drug-naive patients with FEP. Methods: The study sample consisted of 21 drug-naive patients with FEP and 21 healthy participants. Polysomnography recordings were conducted for 2 subsequent nights. A neuropsychological test battery was administered for assessing cognitive functions. The Positive and Negative Syndrome Scale was applied to measure symptom severity of the patients. Spindle detection was performed visually. Results: According to the results of the study, the patient group's percentage of stage N2 sleep and sleep efficiency index was lower than in the control group. Among sleep spindle parameters, spindle density was found to be reduced in the patient group. The results of neuropsychological tests measuring executive functions, learning, and memory support the idea that there is a global cognitive deterioration from the early course of the disorder. In the psychotic group, negative symptoms were negatively correlated with verbal memory, learning, verbal fluency, and semantic organization. We found that the percentage of stage N3 sleep decreased while negative symptom severity increased. In addition, the percentage of stage N1 sleep increased as negative symptom severity increased. Reduction in stage N3 sleep was associated with an impairment in learning, verbal fluency, and response inhibition. The sleep spindle density and cognitive functions did not show any associations. Conclusions: Taken together, these findings suggest that patients with FEP show global cognitive impairment (except for attention and processing speed), which is associated with changes in sleep architecture and higher score in a scale assessing negative symptoms. We conclude that cognitive function and spindle parameters differ nonlinearly among patients with FEP.

The Effect of Training, Used-Hand, and Experience on Endoscopic Surgery Skills in an Educational Computer-Based Simulation Environment (ECE) for Endoneurosurgery Training
(Sage Publications inc, 2019) Cagiltay, Nergiz Ercil; Özçelik, Erol; Ozcelik, Erol; Isikay, Ilkay; Hanalioglu, Sahin; Suslu, Ahmet E.; Yucel, Taskin; Berker, Mustafa; 115500; Psikoloji
Today, virtual simulation environments create alternative hands-on practice opportunities for surgical training. In order to increase the potential benefits of such environments, it is critical to understand the factors that influence them. This study was conducted to determine the effects of training, used-hand, and experience, as well as the interactions between these variables, on endoscopic surgery skills in an educational computer-based surgical simulation environment. A 2-hour computer-based endoneurosurgery simulation training module was developed for this study. Thirty-one novice- and intermediate-level resident surgeons from the departments of neurosurgery and ear, nose, and throat participated in this experimental study. The results suggest that a 2-hour training during a 2-month period through computer-based simulation environment improves the surgical skills of the residents in both-hand tasks, which is necessary for endoscopic surgical procedures but not in dominant hand tasks. Based on the results of this study, it can be concluded that computer-based simulation environments potentially improve surgical skills; however, the scenarios for such training modules need to consider especially the bimanual coordination of hands and should be regularly adapted to the individual skill levels and progresses.
