For information processing tasks, it is an important cognitive skill to manipulate and store information, which is known as information intake. One of the tasks which greatly involve this skill would be a spreadsheet calculation task. In this study, a spreadsheet calculation task is analyzed by the cognitive task analysis based on the cognitive factors having been usef for a model of human information processing. By the results of the cognitive task analysis, the spreadsheet calculation tasks to be used in the experiments are designed and the testbattery of cognitive abilities assessment (CCAB ; complex cognitive asssessment battery) are selected. Then, the features of cognitive demands and a human performance model of the spreadsheet calculation task are suggested by means of correlation analysis, principal component factor analysis, and regression analysis of the results of the experiments on task performances and the assessment of cognitive abilities. Also, the application of the results of the study to job placement and further research issues are described.

GOMS model is a cognitive modeling method of human performance based on Goal, Operators, Methods, Selection rules. GOMS model was originally designed for desktop environment so that it is difficult for GOMS model to be implemented into the mobile environment. In addition, GOMS model would be inaccurate because the original GOMS model was based on serial processing, excluding one of most important human information processing characteristics, parallel processing. Therefore this study was designed to propose a modified GOMS model including mobile computing and parallel processing. In order to encompass mobile environment, an operator of 'look for' was divided into 'visual move to' and 'recognize' whereas 'point to' and 'click' were combined into 'tab.' The results showed that newly introduced operators were necessary to estimate more accurate mobile computing behaviors. In conclusion, modified-GOMS model could predict human performance more accurately than the original GOMS model in the mobile computing environment.

In recent literature on traffic scheduling, the combination of the two-dimensional discrete-time Markov chain (DTMC) and the Markov modulated Poisson process (MMPP) is used to analyze the capacity of VoIP traffic in the cognitive radio system. The performance of the cognitive radio system solely depends on the accuracy of spectrum sensing techniques, the minimization of false alarms, and the scheduling of traffic channels. In this paper, we only emphasize the scheduling of traffic channels (i.e., traffic handling techniques for the primary user [PU] and the secondary user [SU]). We consider the following three different traffic models: the cross-layer analytical model, M/G/1(m) traffic, and the IEEE 802.16e/m scheduling approach to evaluate the performance of the VoIP services of the cognitive radio system from the context of blocking probability and throughput.

이 논문에서는 계산 속도를 개선한 확산모형 분석 도구 SNUDM-G를 소개한다. 확산모형은 다양한 인지과제를 설명하는 데에 적용되어 왔음에도 불구하고 계산적 어려움으로 인해 사용에 제한이 있었다. 특히 확산모형 분석 도구 중 하나인 SNUDM(고성룡 등, 2020)은 확산과정을 근사할 때 2만 개의 자료를 순차적으로 생성하기 때문에 처리 속도 면에서 단점이 있다. 이러한 한계를 극복하기 위해 확산과정을 무작위걷기 방법으로 근사하는 과정에서 그래픽처리장치(GPU)를 사용할 것을 제안한다. 그래픽처리장치를 사용하면 2만 개의 자료를 병렬로 생성할 수 있기 때문에 순차처리로 자료를 생성하는 것에 비해 분석의 속도를 높일 수 있다. GPU를 사용한 SNUDM-G와 CPU를 사용한 SNUDM으로 Ratcliff 등 (2004)의 실험 1 자료를 분석하고 매개변수 복구를 한 결과 SNUDM-G가 SNUDM보다 특정 매개변수에서 다소 높은 값을 추정하였으나, 계산 속도 면에서는 큰 차이로 SNUDM-G가 SNUDM보다 더 빠르게 매개변수를 추정하였다. 이 결과는 이 도구를 이용하여 다양한 인지 과제에 대해 보다 효율적인 확산모형 분석이 가능할 것임을 보여주며, 더 나아가 앞으로 그래픽처리장치를 이용하여 다양한 인지 모형의 처리 속도를 개선할 수 있음을 시사한다.

단어내의 글자들을 교환하여 제시할 경우 원래의 단어로 혼동하는 현상인 글자 교환 효과에 대한 연구가 활발하다. 이는 글자교환 효과에 대한 연구가 시각단어 재인시 글자가 어떻게 부호화 되는지와 단어재인 초기과정에 영향을 주는 변인과 처리과정에 대한 정보를 제공하기 때문이다. 본 소고에서는 글자교환 효과에 대한 기존의 설명 모형들을 살펴보고, 하향적 인지적 처리를 반영하는 모형의 필요성을 논의하였다. 특히 한글 처리의 경우, 글자의 위치가 정해져 있지 않고 유동적이라고 보는 기존의 모델들과 달리 하향식으로 글자의 위치가 어휘 하위 단위인 초성, 중성, 종성으로 지정되어 있다는 가정이 필요하다. 따라서 이에 기반한 모형을 탐색하고 추후 연구방향을 논의하였다.

The purpose of this study was to investigate the relation between the cognitive processes and the mathematical achievement of the 4th grade students. And according to the several studies, there were significant relation between cognitive processes and achievement. Based on the PASS(Planning-Attention-Simultaneous-Successive Processes) Model presented by Das and Naglieri, four cognitive process variables were selected. The results of this study as follows. First, there was not significant relation between attention and mathematical achievement. Second, there was significant relation between planning and mathematical achievement. Third, there was significant relation between simultaneous/successive processes and mathematical achievement. Fourth, the students who got higher scores in the two types (simultaneous/successive)of information processing had more mathematical achievement. Specially, the students who got higher scores in the type of simultaneous information processing had higher scores in mathematical achievement. These results indicated that planning and simultaneous information processing had influence on the mathematical achievement.

This study was contrived Hierarchical Information Search (HIS) model. HIS model is based on a “cognitive process” in which model, comprising basic human information processing mechanize and information interaction. Its process include 3 semantic cognitive processes: Schema-Association LTM, Form Domain, and Alternative Selection. Design methodology consists to elicitate memory, thinking and cognitive response variables. In case study, menu structure of mobile phone was applied. In result, a correlation between predictive error rate and real error rate was .892. and a correlation between selective and real reaction time was .697. This present to suggest a model of how the methodology could be applied to real system design effectively when this was used. HIS model could become one of the most important factors for success of product design. In the perspective, the systemic methodology would contribute to design a quantitative and predictive system.

Purpose: This research presents a practical tool aimed at increasing collaboration between designers and marketers for effective retail space branding. We present a design-related information processing model (DIP Model), which is a schematic map that includes cognitive theories which have design applications to retail space branding. Research design, data and methodology: Through literature review and practitioner opinion survey, 43 theories pertaining to the brand communication in retail spaces were selected, and design applications of the theories were analysed through field trips to stores of global brands. Results: The DIP Model consists of two axes: the information processing axis (i.e., encoding vsretrieval) and the regulatory focus axis(i.e., promotion vs prevention). Theories related to information processing axis are theories that facilitate the encoding and retrieval of information as intended by the company. Theories related to regulatory focus axis are theories that reinforce positive cognition and prevent negative cognition regarding the brand. Conclusions: The DIP Model is developed as a tool to categorise cognitive theories that are applicable to the design of brand communication in retail spaces. As such, the model can provide a better understanding of the role of behavioural design, with the aim of building stronger brands in retail spaces.

In order for humans and robots to interact in daily life, robots need to understand human speech and link it to their actions. This paper proposes a hierarchical behavior model for robot action control using natural language commands. The model, which consists of episodes, primitive actions and atomic functions, uses a sentential cognitive system that includes multiple modules for perception, action, reasoning and memory. Human speech commands are translated to sentences with a natural language processor that are syntactically parsed. A semantic parsing procedure was applied to human speech by analyzing the verbs and phrases of the sentences and linking them to the cognitive information. The cognitive system performed according to the hierarchical behavior model, which consists of episodes, primitive actions and atomic functions, which are implemented in the system. In the experiments, a possible episode, "Water the pot," was tested and its feasibility was evaluated.
