  • The purposes of this study were to analyze the within-group verbal interactions in Thinking Science activities and compare the characteristics of verbal interactions shown by the pupils as well as the differences in help by e teacher in Korea with those in the UK. For the purposes of this study, 16 pupils from comparable groups by cognitive level were selected from both countries. Verbal interactions and teacher help during group discussions were audio/ video taped and the types of students' interactions were classified into interactions related to problem solving, management of classroom loaming and others. The results of this study showed that the verbal interactions in Korean groups were more activated than those in the UK groups. However, the percentages of high level interactions such as metacognitive questions, elaborative suggestions and logical argumentations were higher in the UK groups than those in the Korean groups. Observation of the within-group activities revealed that the pupils of both countries shared some common ground in the following ways; neither recognized the need to formulate the hypothesis in the process of inquiry and that the procedures of discussion were dominated by the pupils of higher cognitive level as the discussion proceeded. It was also observed that the pupils in the UK were considerate in response to the questions posed by both their peers or the teacher, while the pupils in Korea were influenced by their prior knowledge in the subject. Analysis of the teacher help during the inquiry activities showed that the tendency fur the teacher to emphasize the process rather than the product in the procedures of discussion and the extent he/she allowed the pupils to think and consider were closely related to the characteristics of the teacher himself/herself and was found to be a point of commonality in both countries. However, the teachers in the UK revealed the tendency of trying to propose the task to the pupils in concrete and systematic ways and guide the discussion based on the thinking of the pupils, while those in Korea tried to use strategies designed to draw out active verbal interactions among the pupils.

  • Organic solvents are known toxic effects like vertigo, behavioral obstacle, distracting, and peripheral neuropathy in neuron areas. However, there have been few studies how neurotoxic solvents-exposed workers are affected by the cognitive load of preceding working memory tasks. Therefore, we used fMRI as to measure the neural correlates of working memory impairment in occupational workers who had from chronic exposure to organic solvent. Twenty-nine solvent-exposed workers were included in this study. Each participant concluded the verbal N-back tasks (1- and 2-back) during the fMRI acquisition. Within-group analyses showed fronto-parietal networks were active in each condition. Direct comparisons between 1- and 2-back showed higher activation during the 2-back than 1-back. We found that increased activation of these regions at lower task demand is associated with increased cost of implementing.

  • Previous studies have reported that a plausible reference point has a greater anchoring effect than an extreme reference point. It is also known that the anchoring effect decreases when the individual's level of knowledge related to a given item is high. However, there has been no study examining the interaction of the plausibility of the reference point and the difficulty of the given question. Therefore, in this study, the effect of the reference plausibility and the difficulty of the questions on the anchoring effect were examined. The relationship between the response confidence and the anchoring effect was also examined. To do so, easy and difficult questions, plausible and extreme reference points were selected through preliminary research. The experiment was conducted following the 'standard anchoring task procedure'. As results, the extremity of the reference point and the difficulty of the question affected the size of the anchoring effect respectively. The difficulty of the question also affected the confidence of the response. Specifically, when a plausible reference point was presented and when a difficult question was presented, the anchoring effects were increased. In addition, the lower the confidence in one's performances, the greater the influence of the reference point when an extreme reference point was presented. These results show that the plausibility of the given reference point and the difficulty of the item have different effects on the magnitude of the anchoring effect and the degree of confidence. The results of this study support the attitude change perspective regarding the anchoring effect, which suggests that the anchoring effect varies depending on the characteristics of the reference point and the individual's knowledge.

  • This paper summarizes the concept of ludonarrative dissonance that occurred in the realm of full-scale game criticism, and materializes it with the latest work . In the process, it is examined that this game actively utilizes the ludonarrative dissonance to deliver cognitive experiences to players that go beyond the definition of gameness. Along with the all-round development of AAA-class games, the ludonarrative dissonance is emerging as an important task that each game must overcome. On the contrary, however, it should be noted that has a different effect than expected by revealing rather than overcoming the ludonarrative dissonance. The ludonarrative dissonance conveyed by has the effects of ironic interpretative possibilities. This paper looks at dissonance in two dimensions, and the first is the dissonance between the play-narrative structure inside the game. induces the player to recognize the dissonance and actively reconstruct the meaning of the whole game by reminding the player of the dissonance that occurs between the two structures. Second, it stimulates the cognitive dissonance that exists inside the player playing the game beyond the internal structure of the game. That is, by expanding the concept of gameness, it evokes the possibility that games can function more than a tool for convenient self-efficacy. As such, the ludonnarrative dissonance can be a more fundamental redefinition of game nature and an expression of a problem consciousness about the possibility of change.

Empathic Tendency and Theory of Mind Skills in Young Individuals with Schizophrenia: Its' Associations with Self-Reported Schizotypy and Executive Function (젊은 조현병 환자에서 공감경향과 마음이론기술: 자기보고 조현형차원 및 실행기능과의 연관성)

  • Objectives: Social function deficit is known as a core feature of schizophrenia. This study aimed to investigate differences in empathic tendencies and theory of mind (ToM) skills between healthy controls and young individuals with schizophrenia, and to examine the associations between empathic tendencies, ToM skills and schizotypy, and executive function in schizophrenia. Methods: Thirty patients with schizophrenia and 30 healthy controls were enrolled and assessed using the interpersonal relationship index (IRI; perspective taking, fantasy, empathic concern, and personal distress subscales), ToM-Picture Story Task (ToM-PST; sequence and cognitive questionnaire), Wisconsin schizotypy scale (revised physical anhedonia and perceptual aberration), and Stroop tests for empathic tendencies, ToM skills, schizotypy, and executive function. Results: In individuals with schizophrenia, the IRI for perspective taking and ToM-PST score for cognitive function were lower, and the IRI for personal distress was higher than those in healthy controls. The IRIs for perspective taking and fantasy were related to revised physical anhedonia, and that for empathic concern was associated with revised physical anhedonia and perceptual aberration. The ToM-PST score for sequence was associated with the Stroop test score for schizophrenia. Conclusion: These findings indicate deficits in empathic tendencies and ToM skills, which may be independently and primarily associated with schizotypy and executive function in young individuals with schizophrenia.

  • Facial processing of different racial origin has been investigated at various levels including perceptual, emotional, and socio-cultural processing. Particularly, a good deal of studies have been conducted to show "other race effect (ORE)" to indicate that subtle facial information such as identity or emotional expressions are often under-processed in racial out-group members. However, few studies have investigated whether attentional modulation toward racial out-group faces could explain ORE. We investigated whether novelty-driven attentional mechanism is involved in face perception using event-related potential (ERP). Twenty-two Korean (KR) and nine Caucasian-American (AM) participants were presented with emotional faces from the two racial origins while they performed a gender categorization task. KRs showed significantly greater P3 amplitudes to AM than to KR faces indicating that the early attentional processing underlies differential perception of racial out-group faces. Interestingly, P3 was not up-regulated in the AM subjects when they were presented with KR faces, perhaps due to massive habituation to KR faces during everyday social interaction. These results indicate that racial out-group faces are highly salient stimuli which automatically occupy attentional resources, but easily habituated with repeated exposure to the racial-out group.

  • The purposes of this study were to examine the characteristics of teacher help in small group Thinking Science(TS) activities and analyze the way students respond to teacher help. For this study, twenty-four 5th grade and twenty-four 7th grade students were selected, to undertake TS activities. Out of the 8 activities students participated in, the verbal interactions in activity 4 and 6, by students in four small groups, which incorporated relatively active argumentation was analyzed. Students' cognitive level was identified through a science reasoning task and the students were grouped heterogeneously according to their cognitive level. This study showed that teachers predominately used simple confirmation questions in preference to metacognitive question. Also, teacher help varied according to one's personal traits, work experience and degree of activity recognition. It was discovered that when the teacher provided student appropriate metacognitive questions and sufficient feedback, students actively engaged in argumentation. On the other hand, when the teacher asked simple confirmation questions and interfered in the activity, students did not participate in argumentation actively.

  • This study aims to investigate the impact of hotel marketing agility on employee job crafting and service innovative behavior in the context of the uncertainties faced by the Korean hotel industry amidst a rapidly changing business environment. In the post-COVID era, hotel companies need to quickly detect market trends and respond flexibly to secure a competitive advantage and promote sustainable growth. Given the high proportion of face-to-face services in the hotel industry, marketing agility is emerging as a core competency to effectively cope with changing customer demands and market dynamics. However, an organization's agile marketing capabilities only take on true meaning when frontline employees voluntarily redesign their jobs and lead service process innovations. In this regard, job crafting, which refers to employees' active redefinition and modification of their job boundaries, can serve as a link between organizational agility and individual innovative behavior. By empirically analyzing the structural relationship between marketing agility, job crafting, and service innovative behavior in the hotel context, this study applies the concept of agility to the field of human resource management and provides new insights into the antecedents and outcomes of job crafting. The results show that hotel responsiveness has a significant positive impact on all three dimensions of job crafting. In the case of speed and flexibility, they had a significant positive effect on task and relational crafting, but the effect of speed on cognitive crafting was not significant. The implications of the study suggest that hotels' rapid decision-making and execution may actually constrain employees' cognitive crafting activities, such as reflecting on and reinterpreting the meaning and identity of their work. Furthermore, it is expected to provide meaningful insights for hotel managers facing environmental upheavals to seek practical measures to enhance agility and innovativeness.

  • The letter transposition effect is crucial for understanding whether letter position coding within words is fixed. Despite the recognized importance of syllables in Korean word recognition, studies on syllable transposition effects have been inconsistent, indicating a lack of clarity on its mechanisms. Our study aims to address this by analyzing the syllable transposition effect, with a particular focus on distinguishing the influences of orthographic from morphological processing. This focus is due to Korean syllables serving simultaneously as units of orthography and elements of morphology. Through a masked priming lexical decision task with bisyllabic words, we conducted two experiments. Experiment 1 examined the effect across various word types to assess the impact of word origin, while Experiment 2 directly compared the influences of morphological and semantic processing. Results from both experiments showed a significant syllable transposition effect across all word types, pointing to orthographic processing as the key factor in the effect, rather than morphological or semantic factors. This underscores the flexibility of syllable position coding in the early stages of word processing and emphasizes orthographic processing as the primary influence on the syllable transposition effect.

  • This study aims to examine the cognitive and affective changes in university students' writing self-efficacy when engaging in reflective writing classes utilizing ChatGPT. Over ten sessions, reflective writing classes using ChatGPT were conducted for students enrolled in a mandatory writing course at S University in Gyeonggi Province. The reflective journals written by the students during these sessions were meticulously reviewed as qualitative data with statistical analysis of pre- and post-surveys on writing self-efficacy. The results confirmed that utilizing ChatGPT in reflective writing classes positively impacted students' writing self-efficacy. Participants showed increased interest and confidence in their writing abilities when using ChatGPT. It was reported that they received cognitive assistance in outlining and paragraph structuring from samples generated by ChatGPT. Although survey results showed an overall increase in writing self-efficacy, the only statistically significant change was in the 'plagiarism response' category, which means a clear awareness of plagiarism issues. The process of personalizing the ChatGPT-generated samples requires consistent practice, and systematic guidelines on using such helpful tool effectively should be reinforced as a future task.
