Objective: The aim of this study was to investigate the dimensions of agitation in dementia patients using the Turkish version of the Cohen-Mansfield Agitation Inventory (CMAI-T). Materials and Method: The study included 100 patients diagnosed as dementia, according to the DSM-IV-TR. The CMAI-T was administered to the patients' caregivers via face-to-face interviews. The Standardized Mini Mental State Examination (SMMSE) was used to assess cognitive functions. The severity of depression and the functional state of the patients were assessed using the Cornell Scale for Depression in Dementia (CSDD) and the Functional Activities Questionnaire (FAQ). Principal component analysis and varimax rotation were used to determine the factor structure of the CMAI-T. Results: Factor analysis of the CMAI-T indicated a 3-factor structure: physically aggressive agitation, verbal agitation, and physically non-aggressive agitation. In 92% of the patients there >= 1 was agitation behavior during the previous 2 weeks. The CMAI-T total and factor scores were negatively correlated with the SMMSE scores, and positively correlated with the CSDD and the FAQ scores. Conclusions: The CMAI-T yielded 3 factors (physically aggressive agitation, verbal agitation, and physically non-aggressive agitation), which indicated the scale had construct validity Agitation behaviors were associated with cognitive dysfunction, symptoms of depression and general level of functioning. Additional research is necessary to identify the predictors of these dimensions in different dementia samples, and to determine the efficacy of therapeutic interventions.

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) Ozcelik, Erol; Isikay, Ilkay; Hanalioglu, Sahin; Suslu, Ahmet E.; Yucel, Taskin; Berker, Mustafa; Cagiltay, Nergiz Ercil
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.

Evaluation of the Effectiveness of a Gaze-Based Training Intervention on Latent Hazard Anticipation Skills for Young Drivers: a Driving Simulator Study
(Mdpi, 2018) Bicaksiz, Pinar; Palmer, Dakota B.; Hatfield, Nathan; Samuel, Siby; Yamani, Yusuke
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.

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) Cagiltay, Nergiz Ercil; Ozcelik, Erol; Maras, Hakan; Dalveren, Gonca Gokce Menekse
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.

Linking Leadership Style and Workplace Procrastination: the Role of Organizational Citizenship Behavior and Turnover Intention
(Routledge Journals, Taylor & Francis Ltd, 2018) Kose, Asli Goncu; Metin, U. Baran
The primary aim of the present study was to explore whether paternalistic or transformational leadership styles of supervisors were significantly related to workplace procrastination. Moreover, the potential mediation effects of organizational citizenship behaviors (specifically, civic virtue, and conscientiousness) and turnover intention in the link between leadership style and procrastination of the employees were investigated on a heuristic model. Data was collected through online surveys from 126 Turkish full-time office employees. The goodness-of-fit of the proposed model was tested using structural equation modeling and the mediation analysis was performed by bootstrapping. As expected, transformational leadership and organizational citizenship behaviors were negatively related to workplace procrastination. However, there was no significant link between paternalistic leadership and procrastination. Moreover, turnover intention and organizational citizenship behaviors did not mediate this relationship. These findings suggest that transformational leadership style could be a more effective style for diminishing employees' excessive nonwork related behaviors.

Psychometric Properties of the Turkish Version of the Behavioral Emotion Regulation Questionnaire (Berq)
(Routledge Journals, Taylor & Francis Ltd, 2021) Tuna, Ezgi
The Behavioral Emotion Regulation Questionnaire (BERQ) is a self-report measure of the behavioral strategies individuals use to regulate emotions in response to stressful or negative events. The purpose of the present study was to report on the psychometric properties of the Turkish version. The sample was recruited through courses at a semi-private university in Turkey and through social-media announcements. A sample of 320 adults (81.9% females, 18.1% males) with a mean age of 22.03 (SD = 2.73) completed the Turkish translation of the BERQ, the Emotion Regulation Questionnaire, the Difficulties in Emotion Regulation Questionnaire and the Brief Symptom Inventory. Exploratory factor analysis indicated that the Turkish version replicated the 5-factor structure of the original version; yet, a confirmatory factor analysis indicated that the original model showed an inadequate fit to the present data. Internal consistency coefficients of the subscales ranged between 0.72 and 0.88, and the test-retest reliability of subscales over a 3-week interval ranged from 0.51 to 0.70. As in the original version, we found that actively approaching and seeking social support were more adaptive strategies, whereas withdrawal and ignoring were less adaptive strategies. Results were mixed for the seeking distraction subscale. Additionally, withdrawal significantly predicted future depressive and anxiety symptoms. Overall, our results provide support for the Turkish version of the BERQ as a reliable and valid measure of behavioral emotion regulation strategies.

Response Bias in Numerosity Perception at Early Judgments and Systematic Underestimation
(Springer, 2022) Inan, Asli Bahar; Kilic, Asli
Mental number representation relies on mapping numerosity based on nonsymbolic stimuli to symbolic magnitudes. It is known that mental number representation builds on a logarithmic scale, and thus numerosity decisions result in underestimation. In the current study, we investigated the temporal dynamics of numerosity perception in four experiments by employing the response-deadline SAT procedure. We presented random number of dots and required participants to make a numerosity judgment by comparing the perceived number of dots to 50. Using temporal dynamics in numerosity perception allowed us to observe a response bias at early decisions and a systematic underestimation at late decisions. In all three experiments, providing feedback diminished the magnitude of underestimation, whereas in Experiment 3 the absence of feedback resulted in greater underestimation errors. These results were in accordance with the findings that suggested feedback is necessary for the calibration of the mental number representation.

Turkish Muslim Healers: a Qualitative Investigation of Hocas and Their Methods
(Springer, 2020) Canel Cinarbas, Deniz; Tuna, Ezgi; Ar-Karci, Yagmur
A vast majority of Turkish individuals are Muslim, and several Turkish individuals refer to traditional healers to get help for medical and psychological problems. The purpose of the present study was to investigate Turkish traditional healing methods and to delineate the kinds of presenting problems that the clients bring to healers, methods used by the healers, the healing process, and the effect of healing on the clients. For this purpose, 11 participants were interviewed. The data were analyzed using the consensual qualitative research method. Nine domains emerged from the interviews: symptoms, diagnosis, etiology, treatment, response to treatment, characteristics of healers, clients' beliefs and desire to be healed, all healing coming from Allah (God), and characteristics of jinns. The findings were discussed in light of Kleinman's (Patients and healers in the context of culture: an exploration of the borderland between anthropology, medicine, and psychiatry, University of California Press, Berkeley,1980) illness explanatory model and characteristics of Turkish culture.
