Firstly, based on the cognitive learning theory, the cognitive driving behavior model is established, and then the cognitive driving behavior is described and analyzed. Next, based on ANNI, the model and the rule extraction algorithm(ANNI-REA) are designed to explain not only the driving behavior but also the non-sequence. Rules have high fidelity and safety during driving without discretizing continuous input variables. The experimental results on the UCI standard data set and on the self-built driving behavior data set, show that the method is about 0.4% more accurate and about 10% less complex than the common C4.5-REA, Neuro-Rule and REFNE. Further, simulation experiments verify the correctness of the extracted driving rules and the effectiveness of the extraction based on cognitive driving behavior rules. In general, the several driving rules extracted fully reflect the execution mechanism of sequential activity of driving comprehensive cognition, which is of great significance for the traffic of mixed traffic flow under the network of vehicles and future research on unmanned driving.展开更多

Literature as a form of historical culture, the culture of different era, can better reflect the social culture background. Into contact with the cultural background of English-speaking countries, for teachers of English teaching and students' English learning has great significance. Under the basic influence of cultural background in English countries, learning English, will quickly understand the characteristics of syntax and understand the charm of language. Works covered by historical background, English can help students experience a good text artistic conception, thus extended thinking. Under this background, we integrate the basic cognitive theory and style analysis to propose the literature research and development trend that will assist the English community to find better developmental orientation.展开更多

The objective of this study was to evaluate the effectiveness of CATCH program, delivered by dietetic interns and Northern Illinois University (NIU) students, to 3<sup>rd</sup>-5<sup>th</sup> graders in Northern Illinois, in increasing their nutrition knowledge and healthy choices behavior. Methods: In total, 167 elementary school children in grades 3 - 5 in Northern Illinois participated in a non-experimental program evaluation study. We delivered 6 CATCH lessons throughout the academic year to five elementary schools. Lessons were focused on “Go, Slow, and Whoa” food categories to help children understand healthier food choices. Validated questionnaires from the CATCH Global Foundation were administered in classrooms and online, pre/post intervention, to assess nutritional knowledge and healthy choices. Results: Children in third through fifth grades significantly increased their knowledge about nutrient dense foods, p < 0.001, p < 0.001, p < 0.001, respectively. Fourth and fifth graders exhibited a significant increase in their ability to make healthier food choices, p = 0.03 and p = 0.007, respectively. As grade level increased from third to fifth grade, improvement in nutrition knowledge and adoption of healthy food choices did not increase significantly, p = 0.973 and p = 0.637, respectively. Conclusion: We conclude that children in grades 3 - 5 who participated in the 6 lessons of the CATCH program expanded their nutritional knowledge and 4<sup>th</sup> and 5<sup>th</sup> graders improved their ability to make healthier choices. Conducting evaluations of health promotion programs is imperative to determine the impact of the program, as well as to explore possible improvements in content and delivery for future implementation.展开更多

In particular, a theoretical framework was constructed by merging residents' mountain attachment and their environmental values,and awareness of environmental consequences based on the Cognition Behaviour Theory. This research sampled 642 residents with convenience sampling method in Jiuzhaigou and Mount Qingcheng, and structural equation modelling analysis was conducted to identify the relationships among the above variables. Results verified that mountain attachment affected people's awareness of environmental consequences, which then affected their ECB.Environmental values and mountain attachment directly and positively influenced ECB. Moreover,awareness of environmental consequences played the most prominent role in predicting ECB among all the predictors in this study. In all, this study derived several significant implications which can not only contribute to environmental management policies in tourism field but also help to improve the levels of the antecedents of residents' ECB and promote sustainable tourism development in Chinese mountain areas.展开更多

The issue of unpredictability is obviously a problem for English learners. Making things worse, many phrasal verbs are polysemous. For one thing, one phrasal verb may have multiple meanings; for another, several phrasal verbs may have the same or similar meanings. While the fast development of cognitive linguistics theory provides a new perspective for the study of English polysemous phrasal verbs. Researchers apply cognitive linguistic theory into second language acquisition and find that the multiple senses of phrasal verbs are actually systematic and motivated. The present study summarizes studies of polysemous phrasal verbs from the perspective of traditional approaches and cognitive approaches as well as the empirical studies based on it and analyzes the shortage of traditional approaches on phrasal verbs. Lastly, this paper illustrates some drawbacks of empirical study based on the assessment of Boers (2011) and points out some suggestions on further studies.展开更多

It is a leading theory of education at the end of 20th century and the early 21th century. Language itself is a kind of social construct, learning a language is construct personal knowledge. Under the guidance of constructivist learning theory, English teaching has transformed into a student-centered self-construct mode. It created a new situation that students can receive the overall development and personality development through situation setting, collaborative learning and meaning construction.展开更多

Under such circumstances, greater importance has been attached to English teaching of which reading has been given some privileges at the tertiary level in China. Hence, it is very essential for language teachers to have a good understanding about how to teach reading in a college English classroom. This article discusses what reading is, the important issues in teaching reading, and gives some proposals for how to teach reading efficiently in a college English classroom, aiming to give an idea that reading can be learnt effectively if students are motivated, exposed to English language and given chances to use English.展开更多

文摘Background: The Coordinated Approach to Child Health (CATCH) is a school-based health education program, grounded in Social Cognitive Theory (SCT), and designed to improve dietary habits and increase physical activity among children and adolescents. The objective of this study was to evaluate the effectiveness of CATCH program, delivered by dietetic interns and Northern Illinois University (NIU) students, to 3<sup>rd</sup>-5<sup>th</sup> graders in Northern Illinois, in increasing their nutrition knowledge and healthy choices behavior. Methods: In total, 167 elementary school children in grades 3 - 5 in Northern Illinois participated in a non-experimental program evaluation study. We delivered 6 CATCH lessons throughout the academic year to five elementary schools. Lessons were focused on “Go, Slow, and Whoa” food categories to help children understand healthier food choices. Validated questionnaires from the CATCH Global Foundation were administered in classrooms and online, pre/post intervention, to assess nutritional knowledge and healthy choices. Results: Children in third through fifth grades significantly increased their knowledge about nutrient dense foods, p < 0.001, p < 0.001, p < 0.001, respectively. Fourth and fifth graders exhibited a significant increase in their ability to make healthier food choices, p = 0.03 and p = 0.007, respectively. As grade level increased from third to fifth grade, improvement in nutrition knowledge and adoption of healthy food choices did not increase significantly, p = 0.973 and p = 0.637, respectively. Conclusion: We conclude that children in grades 3 - 5 who participated in the 6 lessons of the CATCH program expanded their nutritional knowledge and 4<sup>th</sup> and 5<sup>th</sup> graders improved their ability to make healthier choices. Conducting evaluations of health promotion programs is imperative to determine the impact of the program, as well as to explore possible improvements in content and delivery for future implementation.

文摘This study aimed at gaining an understanding of the formation of residents' Environmental Conservation Behaviour(ECB) to promote sustainable tourism development in Chinese mountain areas. In particular, a theoretical framework was constructed by merging residents' mountain attachment and their environmental values,and awareness of environmental consequences based on the Cognition Behaviour Theory. This research sampled 642 residents with convenience sampling method in Jiuzhaigou and Mount Qingcheng, and structural equation modelling analysis was conducted to identify the relationships among the above variables. Results verified that mountain attachment affected people's awareness of environmental consequences, which then affected their ECB.Environmental values and mountain attachment directly and positively influenced ECB. Moreover,awareness of environmental consequences played the most prominent role in predicting ECB among all the predictors in this study. In all, this study derived several significant implications which can not only contribute to environmental management policies in tourism field but also help to improve the levels of the antecedents of residents' ECB and promote sustainable tourism development in Chinese mountain areas.
文摘This systematic review is focused on the importance of the Bandura Social Cognitive Theory and its theoretical components such as self-efficacy in workplace of today.The themes have been described through the course of the decades.These theories have been utilized heavily in research and real-life case studies,have been further developed by Bandura and other researchers,and have been implemented in organizational psychology.During the past 10 years they have helped in reshaping Human Resources Development.Major latest contributions and applications are discussed touching even the recent outbreak of the pandemic.The influence of the theory is immense and the importance of self-efficacy in the workplace has been addressed and proven by research.
文摘Objective:To develop the Electronic Cigarette Use Scale(ECUS)based on social cognitive theory and test its reliability and validity,so as to provide a scientific tool for evaluating the use of e-cigarette smokers in China.Methods:Based on the review of social cognitive theory and literature analysis,the item pool of ECUS was constructed to form the initial version.From January to March in 2022,using the convenient sampling method,electronic questionnaires were distributed to college students in Guangdong Province through the questionnaire star platform,and a total of 1047 valid questionnaires were collected for item screening.The total sample was randomly divided into sample 1(n=517)and sample 2(n=530)for Exploratory Factor Analysis(EFA)and Confirmatory Factor Analysis(CFA)respectively to further test the reliability and validity of the scale and finally form a 24-item scale.Results:The formal ECUS included 24 items,6 factors were extracted by EFA,and the cumulative explanatory variance was 72.774%.CFA showed that the goodness-of-fit indices were acceptable:χ^(2)/df=2.61,CFI=0.938,TLI=0.928,RMSEA=0.055,90%CI(0.050,0.061),SRMR=0.046,AIC=34694.405,BIC=35036.235.The Cronbach’saof the 24-item scale was 0.898,and the Cronbach’saof each dimension was between 0.839 and 0.954.Both convergent validity and discriminant validity reached the standard.Conclusion:The 24-item ECUS developed in this study has been tested with good reliability and validity and is suitable for evaluating the use of e-cigarette smokers in China.
文摘Phrasal verbs, accounting for a large proportion in modem language, pose numerous challenges to foreign language learners of English, who usually view verb + particle combinations random. The issue of unpredictability is obviously a problem for English learners. Making things worse, many phrasal verbs are polysemous. For one thing, one phrasal verb may have multiple meanings; for another, several phrasal verbs may have the same or similar meanings. While the fast development of cognitive linguistics theory provides a new perspective for the study of English polysemous phrasal verbs. Researchers apply cognitive linguistic theory into second language acquisition and find that the multiple senses of phrasal verbs are actually systematic and motivated. The present study summarizes studies of polysemous phrasal verbs from the perspective of traditional approaches and cognitive approaches as well as the empirical studies based on it and analyzes the shortage of traditional approaches on phrasal verbs. Lastly, this paper illustrates some drawbacks of empirical study based on the assessment of Boers (2011) and points out some suggestions on further studies.
文摘Constructivism is an important branch of cognitive theory. It is a leading theory of education at the end of 20th century and the early 21th century. Language itself is a kind of social construct, learning a language is construct personal knowledge. Under the guidance of constructivist learning theory, English teaching has transformed into a student-centered self-construct mode. It created a new situation that students can receive the overall development and personality development through situation setting, collaborative learning and meaning construction.
文摘The generative operations concerning the transformation between the active and the passive convert successively from PS rules, T-rules, D-structure, NP preposing and postposing, X-bar analysis, to case theory, government, checking theory and head movement. The development of the passive construct mirrors the trend of the progress of Chomskyan theory, evolving from the rule motivations to the principle motivations. The giant leap between the phases of the generative grammar has aroused great curiosity among the scholars and learners of syntax. In this paper, the author will explore the tacit strategy underlying the module changes of TG from the perspective of cognitive science.
文摘English, has not only become the international language as it is spoken by a large number of native speakers of other languages and serves as a language of wider communication but also achieved a genuinely global status owing to its special role recognized in every country. Under such circumstances, greater importance has been attached to English teaching of which reading has been given some privileges at the tertiary level in China. Hence, it is very essential for language teachers to have a good understanding about how to teach reading in a college English classroom. This article discusses what reading is, the important issues in teaching reading, and gives some proposals for how to teach reading efficiently in a college English classroom, aiming to give an idea that reading can be learnt effectively if students are motivated, exposed to English language and given chances to use English.
文摘Cognitive development theories differ on how young students can meaningfully process new information and retain that information for future knowledge-building through scaffolding within their zone of proximal development.More traditional theories like the cognitive load theory adhere to the rote memorization approach by categorizing students as passive learners and the teachers as initiators who provide information in a structured,often rigid format,to be stored and retrieved for future application using their working memory.In contrast,the more progressive theories,like constructivism,are premised on the belief that students should proactively initiate their own learning while teachers act more as facilitators.The current trend in government policy under ESSA is to embrace the latter approach in the classroom,which is also more inclusive of all types of students,especially neurodiverse students.Moreover,teachers can utilize the wider range of assistive technology tools to accommodate and support their students’unique learning styles.
