Article Psychometric Properties Of The Turkish Version Of The Questionnaire Of Group Responsibility Of Cooperation in Learning Teams(2021) Koçak, Hatice Nur; Sayınta, Senanur; Karabacak, Şeyma Nur; Bıçakçı, Ozan; Özçelik, ErolThe Questionnaire of Group Responsibility of Cooperation in Learning Teams (CRCG) was developed to assess university students' responsibility and cooperation skills in learning teams. The presented study aims to develop a Turkish version of the CRCG and to analyze its psychometric properties. The original scale was translated into Turkish and back-translated into English. Participants consisted of 231 (152 women, 79 men) university students. Cronbach's alpha of this questionnaire was high, indicating excellent internal consistency. The temporal reliability of the Turkish version of the CRCG and its convergent validity with the Dimensions of the Learning Organization Questionnaire was acceptable. The confirmatory factor analysis results pointed out that the two-factor structure of the test provided valid results. Taken together, all these results indicate that the questionnaire has good psychometric characteristics. As a result, the Turkish version of CRCG enables researchers and professors to measure students' responsibility and cooperation skills in learning teamsArticle Nietzsche And Heidegger On Meaning: Inferences For The Era Of The Covid-19 Pandemic(2022) Bıçakçı, OzanNietzsche points out that the noble taste of Greek lost its place to dialectic after Socrates, and thus, human beings lost their connection to their nature. After Socrates, through the exclusive use of conscious and logical language, the meaning became fixated in our society and we lost our connection to the dynamism in nature. Considering representations as meanings, in the Heideggerian sense, it should be noted that a represented object always implies a level of existence that is not limited to that representation but points to a Being of that representation. For Heidegger, in line with Nietzsche, however, there is a switch during the Hellenistic period from the understanding of “sign” as "showing for showing" to “sign” as an instrument to "designate", and that switch leads to the creation of representations between sign and its signified (hence the term "designation" with the focus instead on the signified). In today's neoliberal world, similarly, people are lost in and through representations (and even they become a representation to be consumed) and, in this way, lost in an inauthentic way of living. It is, then, not expected for the Covid-19 pandemic to lead us to the authentic way of living because the anxiety around it would be translated into fear, which is an inauthentic way of experiencing anxiety. As a solution, we should reinvent the language where the instinctual language of the real of our bodies and will would prevent the logical language from resulting in the fixation of meaning and representation.Article Influences of Fluency and Familiarity Misattribution on Autobiographical Memory Judgments(2022) İnan, Aslı Bahar; Tekman, HasanFamiliarity caused by fluent processing may be misattributed to past experiences if the source of fluency cannot be determined. This explanation has been presented as the misattribution hypothesis of familiarity to explain the effects of fluency and familiarity in studies using recognition tests on episodic memory. In this study repetition priming was used for autobiographical memory to test the familiarity misattribution hypothesis, which states that familiarity caused by fluent processing can be misattributed to past experience if the source of fluency cannot be identified. The participants’ awareness of the source of fluency was manipulated by presenting either a subliminal or a supraliminal prime before they responded to a Life Event Inventory (LEI) item. The prime was either the same as the verb of the LEI sentence, or a different verb. Participants gave higher confidence ratings if subliminal primes were identical to, rather than different from, the verb of the sentence. Consistent with the hypothesis, if the participants were aware of seeing the primes, this difference disappeared. The results of the experiment showed that manipulating fluency, that is, the ease of processing, could affect confidence ratings about whether an event occurred in the respondents’ past.Article An Investigation of the Differences in the Dark Triad and the Big Five Personality Traits Across Majors(2019) Göncü Köse, Aslı; Ekren, BuseThe Dark Triad (DT) personality traits include interrelated personality constructs which are Machiavellianism, narcissism, and psychopathy, and research has shown that individuals who are high on the DT personality traits tend to choose occupations that provide outcomes compatible with these traits. Supporting this reasoning, the DT is suggested to have impacts on major choices of university students. Previous research has also shown that the Big Five (BF) personality traits influenced educational choices. The main aim of the current study was to examine whether or not self-selection based on these personality characteristics predicted career choices. Data was collected from 659 (359 female) newly enrolled students in seven academic majors (i.e., psychology, law, economics/business, engineering, political science, medicine, and education) in Turkey. Mean scores of the groups were compared using two (gender) by seven (major) analysis of variance with the DT and BF personality traits as the dependent variables. The results revealed that Machiavellianism scores of economics/business and engineering students were significantly higher than those of psychology students. In addition, psychopathy scores of engineering, economics/business, and political science students were higher than those of psychology students. Neuroticism scores of students from psychology departments were higher than those of engineering, economics/business, and political science students. Law and education students’ neuroticism scores were also higher than those of students from engineering and economics/business departments. Finally, interaction effects of major and gender were significant for openness to experience and conscientiousness. The findings are discussed regarding theoretical and practical implications along with suggestions for future research.Article Sleep spindle-related electroencephalograph activity of young adults and its relation to cognitive functions(Ege Univ, 2019) Torun Yazıhan, Nakşidil; Yetkin, Sinan; Yazıhan, Nakşidil TorunObjective: Sleep spindles are phasic bursts of thalamocortical activity, typically defined as 11-16 Hz (in sigma frequency band) with a duration of 0.5 and 2 seconds. Spindles are most prominent during N2 sleep and are a defining feature of this stage. The aim of the present study was to investigate the association between spindle characteristics and cognitive functions of young adults. Methods:The study sample consisted of 17 healthy male subjects aged between 19 and 28 years.The participants had no medical or psychological conditions and were not taking any medications that might affect their sleep pattern and neuropsychological measurements. Polysomnography recordings were conducted from 22:30 to 07:00 hour for two subsequent nights. The first night was for adaptation to the laboratory conditions and to rule out sleep apnea syndrome and periodic leg movements. The second night was used to analyze macro and micro parameters of sleep. A neuropsychological test battery comprising the Serial Digit Learning Test, Raven Standard Progressive Matrices, Verbal Fluency Test,Trail Making A-B, and the Auditory Verbal Learning Test were administered before the second-night sleep session. Sleep spindles in all non-rapid eye movement stage 2 sleep were scored visually from C3-A2 electroencephalogram derivation after polysomnographic analysis was completed. Each 30-sec epoch was analyzed with a high-pass band filtered at 0.3 Hz, and a low-pass band filtered at 35 Hz. Spindle characteristics such as duration, amplitude, mean and peak frequencies were analyzed using the fast Fourier transform algorithm. The association between the characteristics of sleep spindles and the neuropsychological test scores were analyzed using Spearman correlations. Results: Significant positive correlations were found between spindle density and both verbal auditory learning performance and verbal fluency, cognitive flexibility, and semantic organization performances. The serial digit learning test was correlated positively with mean duration, mean frequency, and peak frequency of sleep spindles. Finally, the mean duration, and mean frequency of spindles were positively correlated with verbal fluency, cognitive flexibility, and semantic organization. Conclusion: The associations between spindle features and memory, verbal fluency, and verbal learning abilities were consistent with previous research findings suggesting that sleep spindles might be related to cognitive abilities and the potential to learn. In other words, it might be an indicator of the current level of aptitude for learning.Article Does a correlation exist between fluid intelligence and creativity?(2020) Torun Yazıhan, NakşidilThe aim of the study was to investigate the associations between fluid intelligence and creativity among young adults. The sample consisted of 26 university students who were recruited through convenience sampling method. The Raven Standard Progressive Matrices (RSPM) 9 item-form and a divergent thinking test were used to measure fluent intelligence and creativity, respectively. In order to examine the associations between creativity and fluent intelligence correlational analysis was applied. The Pearson’s correlation coefficient revealed that there was no significant relationship between the tests of divergent thinking and RSPM total score. On the other hand, the results showed a significant positive correlation between the RSPM visuospatial factor and both fluency (r=.47, p<.01) and flexibility (r=.41, p<.01) dimensions of the divergent thinking test. As a result, we suggest that certain basic processes regarding fluid intelligence (e.g. visual spatial reasoning) and creativity operate through common and similar mechanisms. Future studies could investigate the association between these constructs by using neuro-imagining method and focus on how these skills can be integrated into real life situations.Article The Effect of Listening Enjoyable Music Before Study on Learning(2020) Eser, Cansu; Akbaba, Sevcan; Ergül, Mehmet; Özçelik, ErolResearch 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 The Effect of Neurofeedback Training on Variables of Attention in Healthy Adults(2019) Kaynak, Hande; Erdeniz, BurakThe aim of present study is to examine the effect of neurofeedback training on attentional processes in two groups of healthy adult participants. During the experiment, participants in the experimental group were required to complete two puzzles displayed on the computer screen while having neurofeedback training. During this procedure, performance on the puzzles was based on participants’ brain activity that was recorded from the Cz area. Moreover, before and after completion of seven neurofeedback sessions, Stroop task was used to measure selective attention performance. Results for the Stroop task showed that although there was a significant reaction time difference before and after the neurofeedback training, there was no significant main effect of group (experimental vs. control group). Furthermore, the reaction time to complete the puzzles across the sessions did not differ significantly between the experimental and the control group. Improving the training program by increasing the number of training sessions and employing a more attention-demanding task in the training sessions might have resulted in an expected effect of neurofeedbackArticle Are General Intelligence and Implicit Memory Related?: The Effect of Age(2019) Kaynak, HandeThis study investigated the relationship between general intelligence and implicit memory performance in conjunction with aging. Data have been collected from 95 volunteers (49 young-46 older adults). General intelligence was measured by the Raven Standard Progressive Matrices (RSPM) test. Participants’ implicit memory performance was measured by the Word Stem Completion (WSC) task, in which the participants were presented with first three letters of a word and asked to complete this stem with the first word that comes to their mind. Explicit memory performance was also measured to be able to make a comparison with implicit memory performance and to document the differentiation between implicit and explicit memory. Although the same WSC task was used to measure implicit and explicit memory performance separately, the different instructions were used to deduce the different memory types. According to the results of factorial ANOVA, the main effect of age on general intelligence score was found to be statistically significant. After running further analyses by Pearson product-moment correlation coefficients, results indicated that RSPM test total correct score had a tendency to decrease with increasing age and RSPM test completion time had a tendency to increase with aging. Results also showed that implicit WSC task score and RSPM test total correct score were positively correlated. Similarly, explicit WSC task score and RSPM test total correct score were positively correlated, too. However, RSPM test completion time did not differ depending on implicit and explicit memory performances which were measured by WSC task. The present study indicated the relation between implicit WSC task and general intelligence. Within this context, this study is important to draw attention to the contribution of implicit memory measurement which is in the shadow of traditional explicit memory measurements to general intelligence, especially in older population.Article Psychometric properties of the responsibility scale(Ankara Üniversitesi, 2018) Topcu, Merve; Öge, Burak; Gençöz, FarukThis paper aims to develop a free-access reliable and valid scale measuring perceived personal responsibility and discuss its psychometric properties. In the literature responsibility has dened in different ways. Most of the research focus on its situationdependency, but it is possible to nd some limited research about personal responsibility. Within this context, two sets of data collected. The rst data was for factor analysis and split half reliability. Second data was to study concurrent validity. Results revealed that the scale has three constructs, namely, emotional, cognitive, and behavioral factors. Both scale and the factors have good reliability and validity values.
