Book Part Citation - Scopus: 1Implications of cognitive theories for optimizing higher education learning(IGI Global, 2020) Ozcelik, E.; Özçelik, Erol; 115500; PsikolojiCognitive theories have the potential to provide suggestions to design more effective learning environments for higher education. The goal of this chapter is to review cognitive theories and principles based on empirical findings and suggest implications for practice. Working memory theory, distributed cognition theory, dual-process theory, modulatory emotional consolidation theory, mental model theory, metacognitive theory, transfer appropriate processing principle, generation effect, testing effect, and spacing effect are presented in the current study. Based on these theoretical frameworks, novel recommendations for educational practice are suggested. © 2021, IGI Global.

In this study, we present an experimentation conducted with 30 students, comparing performance of a Haptic device with mouse to use a GUI elements commonly used with mouse gestures. This study is inspired by a system that utilizes both mouse and a Haptic device, thus also taking task switching into consideration. We conclude that it is possible to achieve an acceptable performance with a Haptic device in a desktop-like GUI but further study and experimentation is necessary. © Springer International Publishing Switzerland 2015.Article Citation - WoS: 14Citation - Scopus: 14Construct and face validity of the educational computer-based environment (ECE) assessment scenarios for basic endoneurosurgery skills(Springer, 2017) Cagiltay, Nergiz Ercil; Özçelik, Erol; Ozcelik, Erol; Sengul, Gokhan; Berker, Mustafa; 115500; PsikolojiBackground In neurosurgery education, there is a paradigm shift from time-based training to criterion-based model for which competency and assessment becomes very critical. Even virtual reality simulators provide alternatives to improve education and assessment in neurosurgery programs and allow for several objective assessment measures, there are not many tools for assessing the overall performance of trainees. This study aims to develop and validate a tool for assessing the overall performance of participants in a simulation-based endoneurosurgery training environment. Methods A training program was developed in two levels: endoscopy practice and beginning surgical practice based on four scenarios. Then, three experiments were conducted with three corresponding groups of participants (Experiment 1, 45 (32 beginners, 13 experienced), Experiment 2, 53 (40 beginners, 13 experienced), and Experiment 3, 26 (14 novices, 12 intermediate) participants). The results analyzed to understand the common factors among the performance measurements of these experiments. Then, a factor capable of assessing the overall skill levels of surgical residents was extracted. Afterwards, the proposed measure was tested to estimate the experience levels of the participants. Finally, the level of realism of these educational scenarios was assessed. Results The factor formed by time, distance, and accuracy on simulated tasks provided an overall performance indicator. The prediction correctness was very high for the beginners than the one for experienced surgeons in Experiments 1 and 2. When non-dominant hand is used in a surgical procedure-based scenario, skill levels of surgeons can be better predicted. The results indicate that the scenarios in Experiments 1 and 2 can be used as an assessment tool for the beginners, and scenario-2 in Experiment 3 can be used as an assessment tool for intermediate and novice levels. It can be concluded that forming the balance between perceived action capacities and skills is critical for better designing and developing skill assessment surgical simulation tools.Article Citation - WoS: 0Citation - Scopus: 0Remembered or forgotten stimuli: A functional magnetic resonance imaging study on the effects of emotion(Kare Publ, 2020) Ozcelik, Erol; Özçelik, Erol; Kilic, Betul; 115500; PsikolojiObjective: The first aim of this study is to examine why emotional events enhance memory for preceding stimuli. The second goal is to identify brain regions associated with remembering and forgetting by finding brain activation differences during encoding of remembered and forgotten stimuli. The third goal is to examine which brain areas are activated when studying emotional pictures compared to neutral ones. Method: In each trial, a picture of an object followed by an emotional or neutral picture from the Turkish culture were presented to 15 volunteers. The effect of the succeeding pictures on the remembering of preceding stimuli was examined. The participants studied the stimuli in the magnetic resonance scanner and, meanwhile, brain images were taken. The memory performances of the participants were measured with the recognition test administered one week later. Results: Behavioral results suggest that emotion has no effect on memory for preceding stimuli. Functional magnetic resonance imaging results indicate that remembered stimuli compared to forgotten ones caused more activation in left inferior frontal gyrus and left superior medial gyrus. Emotional pictures create more activation in the - mid-temporal gyrus and supramarginal gyrus compared to neutral images. Conclusion: Brain structures in which activations are observed in remembered stimuli compared to forgotten ones (left inferior frontal gyrus and left superior medial gyrus) are responsible for the semantic elaboration and associative memory formation. Thus, it can be concluded that object pictures are remembered because they are processed more deeply. Besides, activations are observed in the areas known to be related to the processing of emotional face expressions when emotional and neutral pictures are compared.Article Attention mediates the effect of emotional arousal on learning outcomes in multimedia learning: an eye-tracking study(2023) Özçelik, Erol; Özçelik, Erol; 115500; PsikolojiRecent 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.Conference Object Citation - WoS: 6Citation - Scopus: 8Simulation-based environments for surgical practice(Ieee, 2017) Dalveren, Gonca Gokce Menekse; Özçelik, Erol; Cagiltay, Nergiz Ercil; Ozcelik, Erol; Maras, Hakan; 115500; PsikolojiModeling and simulation environments provide several insights about the real situations such as endoscopic surgery. Endoscopic surgery requires both hand skills, so, understanding the effect of using dominant or non dominant hand on mental workload is important to better design, develop and implement modeling and simulation environments to support real-life implementations of surgical procedures. This experimental study presents a simulation application of eye-tracking approach to understand mental workload in different hand conditions: dominant hand, non-dominant hand and both hand. The results of the study show that, performing simulated surgical tasks by both hands compared to dominant hand, increases mental workload which is evident by higher pupil size. Accordingly, to manage the mental-load problems of surgeons while performing complex tasks that require both hand usage simulation-based environments can be used. Consequently, collection of detailed information such as eye-data, can give several insights about the behaviors of the surgeons. Also, their required skills can be improved by development of simulation and training environments.Article Short-Term Consolidation of Information for Episodic Memory: The Role of Attention(2021) Özçelik, Erol; Ozcelik, Erol; Tekman, Hasan Gürkan; 115500; PsikolojiHızlı seri görsel sunum, dikkat kırpması, ve ikili görev bozulmaları olgularından elde edilen kanıtlar insanoğlunun kısa-süreli konsolidasyon sürecinde anlamlı bir sınırlılığı olduğunu öne sürmektedir. Kısa-süreli konsolidasyon, görsel temsillerin daha kalıcı bellek biçimlerine transfer edilmesidir. Yapılmış çalışmalar hedef uyaranlardan sonra gösterilen maskelerin bilgilerin konsolidasyonunu yarıda kestiğini göstermesine rağmen, bilgilerin anısal bellek için konsolidasyonunda dikkatin rolü hakkında yeterli kanıt yoktur. Dikkatin ve hedef uyaran ile maske arasındaki uyaran başlangıcı senkronizasyonsuzluğunun (UBS) anısal belleğe etkisini incelemek için üç deney yapılmıştır. Maskeler hedef uyaranlardan sonra değişen UBS'lerde sunulmuştur. Bölünmüş dikkat koşulundaki katılımcılar maskelerin sunumundan sonra dikkat gerektiren ikincil bir iş yaparken tam dikkat koşulundaki katılımcılara böyle bir görev verilmemiştir. Sonuçlar göstermiştir ki; hedef uyaranlar ile maskeler arasındaki UBS'yi düşürmek bölünmüş dikkatte bellek performansını düşürürken tam dikkatte performansı etkilememiştir. Bu bulgular kısa-süreli konsolidasyon sürecinde dikkatin gerekliliğini desteklemektedir.Article The Effect of Listening Enjoyable Music Before Study on Learning(2020) Özçelik, Erol; Akbaba, Sevcan; Ergül, Mehmet; Özçelik, Erol; 115500; PsikolojiResearch studies have suggested that increasing dopamine in a natural way by listening to a short piece of enjoyable music has the potential to improve human performance. However, there is not enough empirical evidence on whether listening to music before studying instructional material enhances learning. Considering this need, the goal of this study is to investigate the effect of listening to enjoyable music before study on learning outcomes. A total of 80 students participated in this experimental study having a between-subjects design. Half of the participants were randomly assigned to the experimental group in which they listened to enjoyable music, whereas the other half were assigned to the control group in which they listened to no music. Afterwards, all the participants studied the instructional materials. The results demonstrate that learning gains were higher in the experimental group than in the control group. Particularly, the results of the current study suggest that when people listen to enjoyable music before they study the instructional materials, they learn better.Article Attention mediates the effect of emotional arousal on learning outcomes in multimedia learning: an eye-tracking study(2023) Özçelik, Erol; Özçelik, Erol; 115500; PsikolojiRecent findings from psychological studies have shown that emotional arousal improves human memory.

Strategies improving these skills are important for developing higher-quality surgical training programs. In this study, the underlying reasons of the navigation control effect on performance in a virtual reality-based navigation environment are evaluated. The participants' performance is measured in conditions: navigation control display and paper-map display. Performance measures were collected from 45 beginners and experienced residents. The results suggest that navigation display significantly improved performance of the participants. Also, navigation was more beneficial for beginners than experienced participants. The underlying reason of the better performance in the navigation condition was due to lower number of looks to the map, which causes attention shifts between information sources. Accordingly, specific training scenarios and user interfaces can be developed to improve the navigation skills of the beginners considering some strategies to lower their number of references to the information sources.
