认知心理学两种研究范式的争论与反思     

贾林祥 《西北师大学报》2005,42(2):45-49

符号加工和联结主义是认知心理学的两种研究范式,二者在认知心理学内部产生了一系列的争论。在一般 认知问题上的争论主要表现在语义理解、心理表征以及一些具体的认知问题上;在方法论问题上的区别主要表现在是 结构模拟、黑箱方法、还原主义还是结构与功能模拟、灰箱方法和整体主义上。两种范式争论的本质问题是究竟哪种 范式更加符合认知过程的本质。联结主义范式似有取代符号加工范式的趋势,但它也不能完全揭示人类的高级认知功 能,因此出现了行为主义的进化论研究范式。  相似文献

Children’s emotional and behavioral responses to peer provocation and early school adjustment     

Maria S. Poulou  Hideko H. Bassett 《Pastoral Care in Education》2018,36(3):205-222

ABSTRACT

Even very young children think about their own and others’ behavior, including emotions. Such cognitions and emotions about the self and others convey information that is crucial to social interactions and relationships. The current study based on an integrated model of emotion processes and cognition in social information processing (SIP) aimed to explore students’ emotional and behavioral responses in SIP choices, and their association with teacher-reported early school adjustment. Two-hundred and thirty pre-school and first-grade primary school students were interviewed using the Challenging Situations Task (CST). CST assessed students’ emotional and behavioral responses to 12 unambiguous hypothetical peer provocation situations. Children’s preschool and first-grade primary teachers rated children’s early school adjustment with the Social Competence and Behavior Evaluation (SCBE-30) measure. The results revealed that children chose mainly sad and angry emotions and socially competent and passive behaviors. We found a relationship both between sad emotions and socially competent behavior choices, and between angry emotion and aggressive behavior choices. Sad emotions and aggressive behavior choices were the main predictors of school adjustment. Children’s responses to peer provocation situations varied depending on how the children interpreted the situations. The results address the importance of children’s SIP and school adjustment.  相似文献

Observations on the temporal correlates of reading failure     

Raymond M. Klein 《Reading and writing》2002,15(1-2):207-231

The definitions of developmental dyslexia andtemporal processing are discussed and severalconstruals of what a temporal processingdeficit might entail are illustrated. Then,using a framework developed by Farmer & Klein(1995), the proposal that a temporal processingdeficit (in vision, audition, or both) might bethe root cause of some proportion of cases ofdevelopmental dyslexia is introduced andvarious research strategies for testing thisproposal are identified. The symposium paperswhich address this general question using arange of these strategies are then criticallyreviewed. It is noted that whereas reading isa recent artifact not yet subject to any directselection pressure, its normal performancerequires the use of, and connections between,the highly evolved modules for visual patternrecognition and language. Within vision andlanguage redundant coding, which permitsperformance in the face of injuries anddegraded input, also makes it difficult todetect subtle deficits (whether temporal, ornot) unless precise tests are used. Yet suchdeficits may degrade performance on tasks (suchas reading) which require the non-copiousconnections between vision and language. Theefficacy of this pathway, I suggest, ismeasured by performance on the rapidautomatized naming (RAN) test.  相似文献
