A PRELIMINARY STUDY TO COMPARE THE SENSORY PROCESSING ABILITIES OF ADULTS WITH MILD INTELLECTUAL DISABILITY

( Jerome Anto Prakash ) 대구대학교 한국특수교육문제연구소 2015 Asia-Pacific Journal of Intellectual Disabilities Vol.2 No.1

The “Life is a sensory experience”(Corem, Porac & Ward 1984). During every moment of our life we experience a whole lot of sensory events. In fact the very experience of being human is imbedded in the sensory events of everyday life. The objective of the study is to identify the sensory processing abilities of adults with Mild Intellectual Disability using sensory profile and to compare the sensory processing abilities of adults with Mild Intellectual Disability. Thirty adults with Mild Intellectual Disability (MID) between the age group of eighteen to thirty five were selected for the study. Adult sensory profile questionnaire developed by Winnie Dunn and Catana E. Brown (2002) were administered. The questionnaire and the five point scoring were explained by the Occupational therapist to the MID adults/Instructors/ Parents and any queries were dully answered. MID adults were encouraged to fill the form completely with assistance. Completed forms were collated for statistical analysis. The duration of the study was one year. Sensory profile manual and Sensory profile questionnaire sheets were used. The score key 1- Almost never, 2- Seldom, 3- Occasionally, 4- Frequently, and 5- Almost always. The study is based on Different subject design involving three conditions. Non-parametric and parametric test were used to analyse the outcome. The result indicates that the sensory processing ability of adults with Mild Intellectual Disability differs in the following items of the sensory profile; Taste/Smell processing, Movement processing, Visual processing, Touch processing, Activity level and Auditory processing. The results were analysed through quadrant grid of the sensory profile. There are four quadrants; quadrant one results indicates low registration, quadrant two results indicates sensation seeking, quadrant three results indicates sensory sensitivity and quadrant four results indicates sensation avoiding. The raw score of each quadrant were compared with the quadrant summary chart of the sensory profile. Identifying and addressing sensory processing problems is an integral part of occupational therapy intervention in adults with MID. Sensory profile is useful in identifying the sensory processing abilities of adults with Mild Intellectual Disability and also contributes to the program planning.

THE IMPACT OF COGNITIVE PROCESSING ON RADICAL AND INCREMENTAL NEWPRODUCT DEVELOPMENT PERFORMANCE

Tetsuo Horiguchi 글로벌지식마케팅경영학회 2016 Global Marketing Conference Vol.2016 No.7

Introduction Since most companies are constantly confronted with incremental technology obsolescence and the risk of disruptive innovations, they have been struggling to pursue both incremental and radical new product developments (NPD). Due to these practical concerns, scholars have conducted research to reveal which factors promote “ambidexterity (O’Reilly & Tushman, 2008)” of both explorative activities, including radical NPD, and exploitative activities, including incremental NPD, mainly focusing on organizational structures and systems. For example, previous studies have suggested organizational structures (Gibson & Birkinshaw, 2004), cross-functional integration (Brettel, Heinemann, Engelen and Neubauer, 2011), and management systems (Benner & Tushman, 2003) are the factors to promote ambidexterity. Furthermore, recent studies have emerged suggesting the importance of cognition in pursuing both radical and incremental NPD (Smith & Tushman, 2005; Eling, Griffin, & Langerak, 2014). Although the importance of cognitive processes in NPD has been suggested in some studies, the research exploring these roles is scarce. Therefore, this study attempts to fill in the gaps by revealing the roles of cognitive processes (analytical processing, intuitive processing, and associative processing) on radical and incremental NPD performance empirically. Theoretical Background and Literature Review The purpose of this section is to attempt to reveal the points not addressed adequately in extant literature. In order to do so, firstly, this section tries to classify the cognitive processing in previous studies, according to some criteria. Secondly, the section reviews the empirical research regarding the effects of cognitive processing on decision-making. Lastly, it goes on to compare the reviewed empirical studies with the classification of cognitive processing that are indicated and attempts to review the gaps in previous research. The research on cognitive processing Referring to the rule-based processing and the associative processing, proposed in Smith & Decoster (2000), as well as the logico-deductive manner of rational choice and the associative thinking, proposed in Gavetti (2005, 2012), this study proposes three types of cognitive processing: analytical, intuitive, and associative processing.Analytical processing involves a comprehensive consideration of various factors, such as market environments, competitors’ behaviors and strategic alternatives, to make a judgement. One example of analytical processing is that we use a 3C framework to make a judgement regarding a new product concept. Intuitive processing involves making a judgement based on intuition, or judging without deliberation. One example of intuitive processing is adopting the product design that arouses feeling of rightness of choice (Dijksterhuis & Nordgren, 2006) or excitement (Agor, 1986) without clear bases. Associative processing involves consciously searching for a past experience or knowledge which is similar to a current situation, and making a judgement based on it. One example of this is when we intentionally recall a past experience in NPD, or a case in another industry that is similar to the current NPD situation, and determine the strategy by following it. The empirical research on the effect of cognitive processing There is an accumulation of empirical research on the effect of cognitive processing on decision making performance, management, and marketing literature. Dean and Sharfman (1996) empirically considered the relationship between the procedural rationality, defined as “the extent to which the decision process involves the collection of information relevant to the decision and the reliance upon analysis of this information in making the choice” (p. 373) and strategic decision effectiveness. Menon, Bharadwaj, Adidam and Edison (1999) empirically examines the relationship between situation analysis, referring to “rational and systematic consideration of the organizational SWOTs in a marketing strategy domains” (p. 21), and market performance, strategy creativity, and organizational learning. Yamashita, Fukudome, Uehara, and Sasaki (2012) studies the relationship between marketing strategy, referring to the extent that the marketer uses STP framework in the phase of decision making, and business unit’s performance. The constructs, such as procedural rationality, situational analysis, and marketing strategy, seem to approximately correspond to the analytical processing indicated in the previous section. Although previous research reviewed so far only focuses on analytical processing, there is research considering other cognitive processing. De Visser et al. (2014) examines the effects of NPD team’s intuitive information processing and analytical information processing on incremental and radical NPD’s overall performance. This study suggests that analytical processing affects overall NPD performance positively while intuitive processing affects only radical NPD performance in a positive manner. Table 1 indicates the arrangement of the reviewed empirical studies. The gaps in the literature From the previous research review, this study indicates three points not addressed adequately in the literature. First, as shown in Table 1, there is little research focusing on cognitive processing aside from analytical processing (especially on associative processing). Second, the research considering the relationship between cognitive processing and radical/ incremental NPD performance is scarce (except for de Visser etal (2014)). Third, little research has considered the effects of the cognitive processing of a new product development (NPD) leader, on the NPD performance. Given these points, this study focuses on the cognitive process of a NPD leader and considers the effects of analytical processing, intuitive processing, and associative processing, on incremental/ radical NPD project performance. Table 1 Research Hypotheses Generally, the uncertainty of incremental NPD projects is low. In such situations, it is relatively easy for NPD leaders to collect and analyze various data for judgements (analytical processing), enabling them to estimate and predict the surrounding situation more accurately. Thus, analytical processing affects the incremental NPD project positively. Using intuitive processing, a NPD leader makes judgements, automatically referring to past repeated experiences (cf. Smith & DeCoster, 2000). These judgements are correct in most cases, but judgement errors are sometimes brought about, due to inaccurate application of repeated experiences to a judgement. Furthermore, due to its automatic and preconscious nature, the bases of the judgement guided by intuitive processing cannot be explained clearly (Smith & DeCoster, 2000; Eling et al., 2014), which seems to increase the frequency of conflicts. Taking these effects in consideration, this study predicts that intuitive processing does not affect incremental NPD project performance. Using associative processing, a NPD leader replaces an uncertain situation with a past experience or knowledge that is more familiar to them, in order to make a judgement. However, such replacement is not effective in incremental NPD projects because, in general, they tend to be less uncertain. Thus, it is predicted that associative processing does not affect incremental NPD project performance. H1a: As a NPD leader uses the analytical processing more frequently in an incremental NPD project, the NPD project performance will be higher. H1b: The frequency of using intuitive processing by a NPD leader does not affect the incremental NPD project performance. H1c: The frequency of using associative processing by a NPD leader does not affect the incremental NPD project performance. Generally, as the needs of radical NPD deviates from organizations’ existing routines (Smith & Tushman, 2005), its uncertainty increases. In these situations, analytical processing is not appropriate for judgements due to the factors such as a lack of information and defined criteria (March, 2006). Part of the previous research suggests the positive effect of intuitive processing on radical NPD performance due to its tendency to generate creative ideas (de Visser et al., 2014). Given this, it is predicted that intuitive processing by a NPD leader positively affects the radical NPD performance. In contrast, it is also said that intuitive processing is likely tocause error of judgement in novel situations or strategies (cf. Miller & Ireland, 2005), and conflicts. Considering these, this study does not posit that any directional relationship between intuitive processing and radical NPD project performance. Associative processing can cope with uncertain situations by relating and drawing similarities from a previous familiar experience to the current uncertain situation (Gavetti, 2012). In addition, since associative processing is a conscious mental activity, its risk of error of judgement is lower than that of intuitive processing (cf. Stanovich & West, 2000). Considering this, it is predicted that there will be a positive effect of associative processing on radical NPD project performance. H2a: The frequency of using analytical processing by a NPD leader does not affect the radical NPD project performance. H2b: The frequency of using intuitive processing by a NPD leader affects the radical NPD project performance. H2c: As a NPD leader uses the associative processing more frequently in a radical NPD project; the NPD project performance will be higher. The depth of NPD leader’s experience refers to the extent that he has engaged in many NPD projects in one product category. The width of the NPD leader’s experience means the extent that he has engaged in NPD projects in various product categories. For want of space, the detailed explanation of H3 is skipped in this abstract. H3: The depth and width of the NPD leader’s experience moderate the relationship between cognitive processing and NPD project performance. Figure 1 METHODOLOGY This study uses the data collected from Japanese high-tech manufacturing companies, through survey research. The collected data will be used to empirically test the hypotheses. At the empirical test, the samples will be divided into two groups according to the NPD radicalness, and each group will be applied hierarchical multiple regression analysis to examine the relationship among the constructs. This study incorporates three independent variables, one dependent variable, three moderator variables and three control variables, into the model. The independent variables are analytical, intuitive, and associative processing. The dependent variable is overall NPD project performance. The moderator variables are NPD radicalness, depth and width of NPD leader’s experience. The control variables are firm size, devoted resource and the development period of a new product. The main variables of this model will be measured as follows. The scales of analytical processing and intuitive processing are developed, referring to those of Epstein et al. (1996) and de Visser et al. (2014). The scale of associative processing is developed for this study by drawing on the extant literature such as Gavetti(2005; 2012). Overall NPD project performance is measured by adopting the scale of Hoegl, Weinkauf, and Gemuenden (2004). The results of the analysis will be reported at the presentation in 2016 Global Marketing Conference in Hong Kong.

Relation between Phonological Processing,Auditory Processing and Speech Perceptionamong Bilingual Poor Readers

Mohan Kumar Kalaiah 대한청각학회 2015 Journal of Audiology & Otology Vol.19 No.3

Background and Objectives: A deficit in phonological processing abilities has been hypothesized as a cause of reading deficits among poor readers, but the precise etiology of this deficit is still unknown. Many studies have investigated the relation of auditory processing and speech perception with phonological processing, while the relation between these are not well understood. Thus, the present study was carried out to investigate the relation between these abilities among poor readers. Subjects and Methods: A total of 20 children between 7-12 years of age participated in the study. Among these 10 were typically developing children and 10 were poor readers. Auditory processing, speech perception in noise and phonological processing skills were assessed in both the groups. Results: Auditory processing was not significantly different between children in both the groups. In contrast, phonological awareness, verbal short-term memory and rapid automatized naming, which reflect phonological processing, and speech perception in noise were found to be significantly affected in poor readers. In addition, the results showed a significant correlation between phonological processing and speech perception in noise. Conclusions: The present study found a significant relationship between speech perception in noise and phonological processing, while there was no relationship between auditory processing and phonological processing. This finding suggests that poor speech perception among poor readers may be one of the contributing factors for phonological processing deficits, which in turn leads to reading difficulties.

DOES PRODUCT CONTEXT COMPLEXITY MATTER IN (IN)CONGRUENT SHOP ENVIRONMENTS? THE INFLUENCE OF PROCESSING FLUENCY ON PRODUCT EVALUATION

Manuela Valta,Donata Vianelli 글로벌지식마케팅경영학회 2017 Global Fashion Management Conference Vol.2017 No.07

Consumers process and evaluate products every day in an increasing number of diverse presentations of products and brands across shop environments. Although consumers may think to react to attributes of the products and the shop environments, there are many contextual factors that influence consumers’ responses. Both products presentation and shop environments differ in visual complexity and ease of processing. For example, products such as fragrances and eyeglasses considerably diverge depending on the visual presentation across multiple stores. Research on processing fluency (e.g., Reber et al., 2004; Winkelman et al., 2003) shows that the processing of any stimulus can be characterized by a variety of parameters that are nonspecific to its content. This stream of work suggests that any variable that facilitates fluent processing results in increased liking, and other positive evaluations. Recent work on context complexity (Orth and Crouch, 2014) suggests that people process a package more fluently when it is presented in a low rather than high complexity context. Further, research on contextual cues (Zhu and Meyers-Levy, 2009) shows that the extent of feature overlap between a context and a target object determines whether a person interprets the target related or not related to the contextual data. Accumulating research suggests that a deeper understanding of the way consumers process multiple contextual cues promises to shed light on our understanding of many areas of consumer research. Although visual appeal is itself multifaceted (Bloch, 1995), much of the current discussion with respect to visual cues does not consider the interaction of multiple shop environments. Given the importance of processing fluency and context effects, we examine the extent to which consumers positively elaborate cognitive processes in relation to product context complexity. Following research in psychology, fluency is the subjective experience of ease with which a person processes a stimulus (Reber et al. 2004). High fluency elicits a positive reaction. We predict that less complex contexts of the product will be easier to process and produce more favorable evaluations of the product. Further, research on contextual cues (Aggarwal and McGill, 2007; Meyers-Levy and Sternthal, 1993) shows that consumers better overlap contextual cues when cues are moderately congruent rather than low congruent. This suggests that consumers respond more favourably to moderate congruent shop environments. Studies Two studies tested our prediction that product context complexity across shop environments affects consumer’s processing fluency, liking, and product evaluation. In both studies, participants were provided with pictures of real products and shop environments. Images were manipulated to disguise brand names. Participants were recruited online through the platform Prolific Academic. Study 1 tested the hypothesized negative effect of product context complexity on processing fluency, and liking. The final section of the survey asked for personal information, including gender, age, and style of reasoning. These variables had no significant impact on the dependent variables of interest and were excluded from further analysis. In study 1, ninety participants (mean age = 34.20, 63 females) were randomly assigned to one of the two conditions (product context complexity: low vs. high). They viewed one randomly selected picture of cosmetics displayed on counter displays across two different stores. Cosmetics was chosen due to the large variance in products presentation across multiple retailers. In a pretest, 87 participants rated perceived complexity of the display to examine whether the display complexity differs across the two conditions. The manipulation was successful (Mlow = 2.32 vs. Mhigh = 3.68; F(1,85) =24.299, p < 0.001). Running one-way ANOVA with product context complexity as independent variable and processing fluency as dependent variable a significant main effect of the context complexity (M = 5.05 vs. M = 4.37; F (1,87) = 3.913, p < 0.05). To test our prediction that liking is mediated by processing fluency of product context complexity, a mediation analysis was conducted (PROCESS model 4: Hayes, 2014). Bootstrap estimation confirmed that processing fluency mediates the influence of product context complexity on liking (simple slope = 0.44, LLCI = 0.01, ULCI = 0.94). In study 2, our aim was to corroborate and extend study 1 findings by testing product context complexity in congruent and less congruent shop environments. One hundred seventy-seven participants (mean age = 35,31, 80 females) viewed one randomly selected combination of chocolate shop environments. As in study 1, we chose chocolate due to the large variance in products presentation across multiple retailers. Chocolate was displayed on tower displays (products context complexity: low vs. high), and matched with the overall in-store presentation of three chocolate shop environments (shop environment congruence: low vs. moderate vs. high). After processing the pictures, participants were asked to rate processing fluency, liking, and product evaluation. Similarly to Study 1, the final section of the survey asked for personal information, including gender, age, and shopping goal. Again, these variables had no significant impact on the dependent variables of interest and were excluded from further analysis. Two pretests confirmed that our manipulation of product context complexity (Mlow = 1.96 vs. Mhigh = 4.01, F(1,57) = 23.464, p < 0.001) and store processing fluency (Mlow = 3.50 vs. Mmoderate = 4.14 vs. Mhigh = 5.10, F(1,109) = 10.465, p < 0.005) were successful. Running a factorial ANOVA with processing fluency as dependent variable indicated a nonsignificant main effect of product context complexity. Shop environment congruence had a significant main effect (F(2,171) = 6.561, p < 0.005). Contrasts analysis revealed significant differences between the high congruence/context complexity condition and the low congruence/context complexity condition, and between the moderate congruence/context complexity condition and the low congruence/context complexity condition (all ps < 0.005). We then tested the prediction that processing fluency mediates the effects of shop environment congruence on liking and product evaluation through product context complexity as moderator. We used a moderated mediation analysis with the bootstrap PROCESS model 8: Hayes, 2014). There was a significant conditional indirect effect of shop environment congruence on liking though product context complexity in the high context complexity condition, b = -0.280, LLCI = -0.509, ULCI = -0.120. A similar estimation with product evaluation as the independent variable revealed that processing fluency mediated the relationship between significant shop environment congruence and product evaluation though product context complexity in the high context complexity condition, b = -0.375, LLCI = -0.631, ULCI = -0.153). Discussion Our findings demonstrated the influence of product context complexity on processing fluency and product evaluation. The results showed that less context complexity leads to an ease of processing. Study 1 confirmed the negative relationship between product context complexity and processing fluency. Further, study 1 demonstrates a mediation mechanism of processing fluency on liking. This result confirms prior work on processing fluency (Reber et al., 2004). Further. we extend previous work on visual complexity (Orth and Crouch 2014) by demonstrating that low congruence shop environments may influence consumer processing fluency. In study 2, we looked at how consumers respond to complex and less complex presentation of products in congruent and less congruent shop environments. Our results support research on contextual cues (Zhu and Meyers-Levy, 2009) by showing an interesting path of complex contextual cues. Complex contexts may affect consumer’s evaluation of products. This pattern is more pronounced in low congruent shop environments. Consumers may evaluate much less favorably visually complex contexts in low congruence shop environments than in congruent shop environment. Such behavior is due to the extent to which consumers overlap the shop environment and the target product. This research shed light on how consumers combine retail and product cues. By integrating research on processing fluency and contextual cues, our work allows a better crafting product design and retail strategies. Apart from the theoretical contributions, this research provides marketing manager with insights into how to develop easier to process shop environment for consumers. The results suggest that when products are presented with complex contexts, consumers respond less favorably to the visual appearance of their products. For retail managers, the results provide insight into why it might be especially difficult to process more complex settings of the products. The results suggest that to make a shop environment more favorable, managers have to find solutions to reallocate complex contextual cues of the products. This could be done through developing more congruent areas within the store. Given the growing importance of visual strategies in retailing, our research gives managers suitable solutions to allocate in-store resources.

English L2 Speakers' Processing of Morphologically Simplex and Suffixed Words

한국언어학회 한국언어학회 2015 언어 Vol.40 No.3

Yun, Gwanhi. 2015. English L2 Speakers’ Processing of Morphologically Simplex and Suffixed Words Korean Journal of Linguistics, 40-3, 40-3, 423-448. Recent studies on morphological processing have shown that morphologically complex words such as class II affixed words or regular inflected words are processed by decomposition whereas class I affixed words and irregular inflected words are processed as whole-word units. The present study aims at exploring whether such patterns found for native speakers of English emerge differently in accordance with L2 proficiency. First, the results attained for intermediate proficiency learners show that complex words benefit from more processing efficiency than simplex words, derivational words cost more difficulty processing than inflected words for high-frequency condition, and class II suffixed words suffer heavier processing burden than class I suffixed words. Second, the results for advanced learner group show that simplex words are processed more efficiently than complex words, inflectional words are processed with more difficulty than derivational words in low-frequency words, and class II suffixed words pay more processing cost than class I suffixed words in high-frequency condition. These findings suggest that L2 processing mode for complex words is contingent on proficiency level and surface frequency is mediated in the processing. Furthermore, it is implied that though the extent of dual-route processing is not as strong as that of target language users, L2 learners seem to be under progress towards dual-route processing as the growth of proficiency.

비정형 빅데이터의 실시간 복합 이벤트 탐지를 위한 기법

이준희,백성하,이순조,배해영 대한공간정보학회 2012 Spatial Information Research Vol.20 No.5

Recently, due to the growth of social media and spread of smart-phone, the amount of data has considerably increased by full use of SNS (Social Network Service). According to it, the Big Data concept is come up and many researchers are seeking solutions to make the best use of big data. To maximize the creative value of the big data held by many companies, it is required to combine them with existing data. The physical and theoretical storage structures of data sources are so different that a system which can integrate and manage them is needed. In order to process big data, MapReduce is developed as a system which has advantages over processing data fast by distributed processing. However, it is difficult to construct and store a system for all key words. Due to the process of storage and search, it is to some extent difficult to do real-time processing. And it makes extra expenses to process complex event without structure of processing different data. In order to solve this problem, the existing Complex Event Processing System is supposed to be used. When it comes to complex event processing system, it gets data from different sources and combines them with each other to make it possible to do complex event processing that is useful for real-time processing specially in stream data. Nevertheless, unstructured data based on text of SNS and internet articles is managed as text type and there is a need to compare strings every time the query processing should be done. And it results in poor performance. Therefore, we try to make it possible to manage unstructured data and do query process fast in complex event processing system. And we extend the data complex function for giving theoretical schema of string. It is completed by changing the string key word into integer type with filtering which uses keyword set. In addition, by using the Complex Event Processing System and processing stream data at real-time of in-memory, we try to reduce the time of reading the query processing after it is stored in the disk. 최근 소셜 미디어의 발달과 스마트폰의 확산으로 SNS(Social Network Service)가 활성화가 되면서 데이터양이 폭발적으로 증가하였다. 이에 맞춰 빅데이터 개념이 새롭게 대두되었으며, 빅데이터를 활용하기 위한 많은 방안이 연구되고 있다. 여러 기업이 보유한 빅데이터의 가치창출을 극대화하기 위해 기존 데이터와의 융합이 필요하며, 물리적, 논리적 저장구조가 다른 이기종 데이터 소스를 통합하고 관리하기 위한 시스템이 필요하다. 빅데이터를 처리하기 위한 시스템인 맵리듀스는 분산처리를 활용하여 빠른게 데이터를 처리한다는 이점이 있으나 모든 키워드에 대해 시스템을 구축하여 저장 및 검색 등의 과정을 거치므로 실시간 처리에 어려움이 따른다. 또한, 이기종 데이터를 처리하는 구조가 없어 복합 이벤트를 처리하는데 추가 비용이 발생할 수 있다. 이를 해결하는 방안으로 기존에 연구된 복합 이벤트 처리 시스템을 활용하여 실시간 복합 이벤트 탐지를 위한 기법을 제안하고자 한다. 복합 이벤트 처리 시스템은 서로 다른 이기종 데이터 소스로부터 각각의 데이터들을 통합하고 이벤트들의 조합이 가능하며 스트림 데이터를 즉시 처리할 수 있어 실시간 처리에 유용하다. 그러나 SNS, 인터넷 기사 등 텍스트 기반의 비정형 데이터를 텍스트형으로 관리하고 있어 빅데이터에 대한 질의가 요청될 때마다 문자열 비교를 해야 하므로 성능저하가 발생할 여지가 있다. 따라서 복합 이벤트 처리 시스템에서 비정형 데이터를 관리하고 질의처리가 가능하도록 문자열의 논리적 스키마를 부여하고 데이터 통합 기능을 제안한다. 그리고 키워드 셋을 이용한 필터링 기능으로 문자열의 키워드를 정수형으로 변환함으로써 반복적인 비교 연산을 줄인다. 또한, 복합 이벤트 처리 시스템을 활용하면 인 메모리(In-memory)에서 실시간 스트림 데이터를 처리함으로써 디스크에 저장하고 불러들이는 시간을 줄여 성능 향상을 가져온다.

오미형 한국아동교육학회 2005 아동교육 Vol.14 No.1

본 연구에서는 유아의 정보처리 양식에 따라 유아가 구성하는 이야기의 구조와 길이에 차이가 있는지를 살펴보고자 하였다. 연구의 대상을 표집하기 위해 한국판K-ABC 지능검사를 실시하여 유아의 정보처리 유형에 따라 동시처리형 11명과 순차처리형 15명을 무선 표집하였다. 이야기 구성 검사 도구로 글없는 그림책을 사용하였으며 이야기구성력과 이야기의 길이를 측정하였다. 이야기구조와 이야기길이를 종속변인으로 하고 유아의 정보처리양식을 독립변인으로 하여 MANOVA를 실시하였다. 연구결과 유아가 구성한 이01기의 구조와 길이는 유아의 정보처리 유형에 따라 차이가 있는 것으로 나타났다. The purpose of this study was to examine the differences of Story Construction according to children with a strength in sequential processing or simultaneous processing. For sampling the subject of this study, Korean version K-ABC Intelligence Test(Moon, Soo-Back, 1997)was conducted 96 children aged 5 who were attending B kindergarten in U city. As a result of this test, 15 children of sequential processing style and 15 children of simultaneous processing style were sampled randomly. As for test tool, 'story construction from a picture book' which was made by Kraayenoord & Paris, was modified, used. Data was analyzed by MANOVA according to problems. Followings are the results of this study: Firstly, there was no significant difference between sequential processing style and simultaneous processing style in 'metalinguistics' of story construction, but in cases of 'comments about pictures' and 'elaboration and personal involvement', the children group of sequential processing style got statistically higher grades than the children group of simultaneous processing style. And in cases of 'revision strategies' and 'theme/moral' of story construction, the children group of simultaneous processing style got statistically higher grades than the children group of sequential processing style. Secondly, there was significant differences between children's information processing style in story length. That is, the children group of sequential processing style made longer story than the children group of simultaneous processing style.

자폐스펙트럼장애 아동에서 대소변 가림 여부에 따른 사회지수 및 감각처리기능 비교

Purpose : The purpose of this study was to investigate the differences in social quotient and sensory processing function between completed-toileting and incomplete-toileting children with autism spectrum disorder (ASD). We aims to provide a basis for the training of children with autism spectrum disorders. Methods : The subjects of this research were children with ASD, aged from 4 to 7, receiving sensory integration therapy at the H-Child Development Research Center in Busan, South Korea. After recruiting 30 parents who had children with ASD, we interviewed them and we divided their children into completed-toileting group and incomplete-toileting group based on the past researches. We assessed them using the Social Maturity Scale and Sensory Profile. Spearman correlation was used to analyze between the sensory processing score and social quotient. Mann-Whitney U test was used to compare the Sensory Profile scores of the two groups. Results : The social quotient was correlated with the sensory processing score in the most of component as for auditory processing, vestibular processing, touch processing, multisensory processing, orosensory processing, except for visual processing. The groups of completed-toileting and incomplete-toileting group showed statistically significant intergroup difference in sensory seeking, emotional reactive, oral-sensory sensitivity, and inattention/distractibility in the sensory factor region. No statistically significant difference from intergroup was observed in any modulation areas, nor in behavioral & emotional response domains. Conclusion : A significant intergroup difference was observed in the most of sensory processing areas, except for modulation areas and behavioral & emotional response domains. The result revealed that toileting is significantly correlated with sensory processing. Therefore, this study suggests that the sensory processing function should be considered in the toilet training of children with ASD.
