  • As the use of digital media is becoming more universal and is being used in early-childhood education, understanding the effects of digital media on development is required. The purpose of this study was to examine whether child performance on a spatial cognition task depends on the type of media used to present the task and if the effect of media type is different depending on child's age and sex. To do this, a spatial cognition task set (consisting of direction, rotation, symmetry, conjugation, and part/whole tasks) was prepared, and these tasks were presented to 60 3-, 4-, and 5-year-old children using paper- and tablet-based measures. Our results showed that the correct answer rate of task performance differed significantly when completing the task on a tablet than when completing the task on paper. Generally, response times when completing the tasks on a tablet was significantly shorter than when completing the tasks on paper. Although there was no interaction between the type of media and age, and partial interaction was found between the type of media and sex. This result implies an influence of digital stimulation on child performance on the spatial cognitive task. This study provides a basic understanding for follow-up studies to examine the consequences of exposure to digital stimulation.

  • Although market orientation as the implementation of the marketing concept has long been a major subject in marketing, firms with market orientation do not necessarily come with high performance, showing mixed results in literature. There have been attempts to link market orientation-firm performance until recently with different mediators, but the appreciation on market orientation has been faded in practice. This study focuses on two possibilities for the causes of these problems. 1) Previous studies have overlooked the qualitative aspects of market orientation, 2) have focused on the performance at corporate level. To provide a generalized performance-generation framework, this study demonstrates the market information quality as a moderating variable and introduces the task performance of employees as a universal mediator between market orientation and the firm performance. As the result of this study, we confirmed the positive role of the market information quality and employees' task performance in market orientation-Firm Performance. The relationship between market orientation and employee's task performance becomes stronger when market information quality is high in value. We highlighted the performance generating mechanism of market orientation, regardless of context. This research provides new insights for marketing scholars and managers with regard to both activities and quality of market information and how market orientation affects individual and firm level performance.

  • Driven by the development of information technologies, information system (IS) use has been common even in military organizations. In particular, field artillery is currently using the Battalion Tactical Commanding System-A1 (BTCS-A1) to improve fire support. The use of BTCS-A1 makes fire-commanding processes simple and autonomous, which leads to shorten time to support fire. Although BTCS-A1 has been considered as a helpful system, there still exists some dispute regarding its effectiveness and impact on task performance. By conceptualizing BTCS-A1 use as appropriation, this study investigates how BTCS-A1 appropriation promotes task performance. We also hypothesize that IS quality, organizational pressure (institutional pressure and supervisor influence), and team climate (team learning climate and team empowerment climate) increase the appropriation. Survey results show that organizational pressure and team climate promote BTCS-A1 appropriation, which improves users' task performance. However, effect of IS quality is not significant. Theoretical and practical implications are presented.

  • The purpose of this study was to investigate the possibility of providing familiar tasks as a treatment option to decrease echolalia. Two comparisons were made:One was to compare ‘conversation condition’ and ‘task performance condition.’ and the other was to compare ‘task performance alone condition’ and ‘task performance along with contingency of reinforcement condition.’ Two echolalic children aged 12 and 13 years participated in the experiment and A-B-A-B-BC-B-BC design was used, in which A was conversation only, B was task performance, and C was task performance along with contingency of reinforcement. In the A condition, the therapist asked easy and short questions to the child;in the B condition the child was given familiar tasks with short instruction, and in BC condition, each child was reinforced for his performance on given tasks, in which immediate echolalia was controlled through his hands being held down for 5 seconds. Delayed echolalia was recorded without any intervention being given. Each child was put into each of the 7 treatment conditions. With a 15 minutes session, each child went through 5 to 6 sessions per day for 2 weeks. The mean echolalia(immediate) rates across the 7 treatment conditions were:For child 1, A(99%)-B(65%)-A(95%)-B(10%)-BC(7%)-B(6%)- BC(7%) and for child 2, A(67%)-B(62%)-A(63%)-B(35%)-BC(8%)-B(4%)-BC(0%). As to the generalization of the treatment effect of immediate echolalia to the untreated delayed echolalia, there was shown a drastic reduction of delayed echolalia in child 2:A(35%)-B(57%)-A(56%)-B(40%)-BC(8%)-B(5%)-BC(9%). Child l’s delayed echolalia was negligible(mean=3%) pre-and post treatments. In conclusion, the results of this study clearly show that providing a task performance setting with familiar tasks can certainly be helpful for minimizing echolalic response, and along with the use of the contingency of reinforcement technique it can further not only correct echolalic behavior to a negligible degree but also help the echolalic child generalize its treatment effect to the child’ overall language improvement.

  • Prior studies were limited in the comparison of false belief tasks with desire tasks due to lack of consideration of level of executive functions. To compensate for this, executive functions were included in new preference-related and game-related tasks of conflicting desire. These tasks were administered to 246 preschoolers ranging from 2.5 to 4 years of age. Statistical analysis was by one-way ANOVA and repeated measures ANOVA. Results showed significant main effects depending on age and task type. Younger children lacked ability of executive function, such as inhibition and working memory. Older preschoolers averaged better scores on task performance, showing that it is difficult for younger children to control their own desires and select the contradicted view.

  • This studied investigated children's music identification, classification, and seriation cognitive task performance abilities by age and sex. The subjects were l20 six-, eight-, and ten-year-old school children. There were significant positive correlations among music cognition tasks and significant age and sex differences within each of the music tasks. Ten-year-old children were more likely to complete their music identification tasks than the younger children and girls were more likely than boys to complete their music identification tasks. Eight- and 10-year-old children were more likely to complete their music classification tasks than the younger group. Piagetian stage theory was demonstrated in children's music classification task performance. There was an age-related increase in the performance of the music seriation tasks. Developmental sequential theory was demonstrated in music seriation performance.

  • In recent years, pair programming has become a widely used approach for development of information systems. According to a worldwide survey, 35 percent of 104 development projects reported using pair programming. However, previous studies have shown rather mixed results in terms of the effectiveness of pair programming, comparing to individual or independent programming. This paper, therefore, uses a lab setting to control some of the variables that appear to have caused conflicting results in earlier studies. Writing SQL Queries for given problem statements is selected as the task the subjects to solve. One key issue addressed is the distribution of work load among the pair programmers and the independent programmers. Another is communication among co-workers as would occur in a real-world system development environment. The results of this study indicate there is no significant difference in task performance pair programming and independent programming.

  • In a contemporary organization, the role of social capital has been increasingly important in sharpening knowledge management practices. The primary objective of this paper is to propose a research model to measure the effects of social capital on individual performance. The model also investigates the mediating mechanism of knowledge acquisition and knowledge transformation, both of which are critical in fostering an enterprise's absorptive capacity. The field data was collected from a knowledge-centric organization. The analysis result reveals that shared goal is crucial in enabling knowledge processes. Furthermore, it is found that knowledge transformation rather than knowledge acquisition is more likely to lead to individual task performance.
