Associated Factors of Psychological Symptoms Among Unemployed Turkish Adults: The Role of Personality Factors and Rumination
(Sage Publications inc, 2020) Tuna, Ezgi; Balci, Seyma; 163887
Unemployment has been associated with adverse mental health outcomes including depression and suicide. In the last decades, unemployment rates have increased substantially in Turkey; yet, factors and mechanisms that play a role in experiencing psychological symptoms among unemployed individuals are not well understood. The aim of this study was to investigate the role of personality characteristics on psychological symptoms among unemployed Turkish adults and to test the mediating role of rumination as a dysfunctional cognitive strategy. The sample consisted of 217 unemployed Turkish adults who completed self-report measures on neuroticism, external locus of control, rumination, and psychological symptoms. The results of the structural equation modeling indicated that rumination partially mediated the relationship between personality variables (i.e., neuroticism and external locus of control) and psychological symptoms, thus verifying the hypothesis of the study. The direct paths from trait neuroticism and external locus of control to psychological symptoms were also significant. Results revealed that a tendency to attribute future outcomes to external factors and an increased tendency to experience negative emotions are associated with engaging passively in rumination, which in turn predicts psychological symptoms. Interventions are suggested to focus on effective coping strategies along with increasing individuals' perceived control over life and future.

Enhancing Multimedia Learning by Emotional Arousal
(Routledge Journals, Taylor & Francis Ltd, 2024) Ozcelik, Erol; Özçelik, Erol; Arslan-Ari, Ismahan; Psikoloji
Several studies in multimedia learning have examined the effect of emotional design. Recent findings from cognitive psychology provide opportunities for educators to use more direct ways of manipulating emotion to enhance learning. These studies have shown that emotionally arousing words and pictures are remembered better than neutral ones. Building upon these findings, this experimental study investigates the effect of arousal of instructional materials on learning. A total of 154 participants were randomly divided into a "high-emotional arousal" and a "low-emotional arousal" group in a between-subjects design. These results suggest that emotional arousal enhanced learning. Mediation analyses show that the effect of arousal on learning was partially mediated by interest. Accordingly, emotional arousal increased interest, which in turn improved transfer scores. The findings imply that motivational factors such as situational interest encouraged elaborative processing and deeper levels of learning. The direct effect of emotional arousal on learning was also significant.

Factors Influencing Children’s Appraisals of Interparental Conflict: The Role of Parent-Child Relationship Quality
(Sage Publications inc, 2020) Selcuk, S. Ule; Isanoglu, Zulal; Sayil, Melike; Sumer, Nebi; Berument, Sibel Kazak
The cognitive contextual model proposes that children's appraisals of interparental conflict (IPC) can influence their adjustment. In addition, previous research revealed that interparental disputes may reflect on parent-child relationship that is linked with children's self-blame and threat appraisals concerning IPC. However, there is a scarcity of research directly addressing the intervening role of the parent-child relationship on children's appraisals of IPC. Thus, we investigated the mediating role of different aspects of the parent-child relationship (i.e., psychological control, warmth, and attachment security) in the link between IPC and self-blame and threat appraisals. Participants were 1,309 children, their mothers, and their fathers. SEM analyses indicated that higher IPC was related to higher parental psychological control and lower child attachment security, which in turn was associated with higher self-blame or threat appraisals. The pattern of relationships was similar across child and parent gender.

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.

Locus of Control as a Mediator of the Relationships Between Motivational Systems and Trait Anxiety
(Sage Publications inc, 2024) Kaynak, Hande; Demir, Yağmur; Turan, Aysu; Demir, Yagmur; 101097; İngiliz Dili ve Edebiyatı
The Reinforcement Sensitivity Theory, first proposed by Gray and later revised, describes three motivational systems: Behavioral Inhibition System (BIS), Behavioral Activation System (BAS), and Fight-Flight-Freeze System (FFFS). Studies have shown that high BIS and FFFS activation are positively related to anxiety symptoms, yet the relationship between BAS and anxiety remains unclear. Research data have also suggested that anxiety symptoms occur with the loss of perceived control. Thus, although studies on the direct effect of locus of control (LOC) on trait anxiety have accumulated for many years, the issue of how LOC may mediate the relationship between BIS/BAS/FFFS sensitivity and anxiety has not been addressed. This study aimed to explore the mediating role of LOC orientation on trait anxiety among young adults in association with these three motivational systems. Cross-sectional data were obtained from 422 volunteers. The BIS/BAS Scale, Trait Anxiety Inventory, and Rotter's Internal-External LOC Scale were applied. A series of mediation analyses were performed to estimate total, indirect, and direct effects. The results showed that BIS and FFFS positively predicted trait anxiety. In addition, LOC positively predicted trait anxiety and BIS. The results of the mediation analyses indicated that LOC functioned as a partial mediator between BIS and trait anxiety. This finding revealed that a high BIS level, one of the motivational systems, was associated with external LOC, which in turn contributed to reporting high trait anxiety in young adults. Hence, BIS and external LOC orientation could be suggested as risk factors for trait anxiety. As the external LOC orientation of individuals with high punishment sensitivity increased, their trait anxiety levels also increased. Therefore, it was suggested that it might be useful to be aware that LOC orientations of individuals with BIS sensitivity may pose a risk for trait anxiety.

Response bias in numerosity perception at early judgments and systematic underestimation
(Springer, 2022) Kilic, Asli; İnan, Aslı Bahar; Inan, Asli Bahar; 101713; Psikoloji
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.

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.
