The definition of development 生命期間 身心層面 改變與不變
time 生命期間 • 嬰兒 • 幼兒 • 學齡兒童 • 青少年 • 成人 • 老人
domains physical development(身體生理發展) 身 motor skills development(動作發展) 心 sensation and perceptual development(感覺知覺發展) 層 cognitive development(認知發展) 面 social cognition development(社會認知發展) social development(社會發展)
Cognitive development Cognition and cognitive development • Cognition:the activity of knowing and the processes of acquiring knowledge. • Cognitive development:age-related changes occur in mental activities.
Approaches to studying cognitive development • Piaget’s cognitive-developmental theory • Vygotsky’s sociocultrual viewpoint • Information-processing perspectives • Psychometric viewpoints
Piaget’s cognitive-developmental theory • 感覺動作期(sensorimotor stage, 0-2yr) • 前運思期(preoperation stage, 2-6,7yr) • 具體運思期(concrete operational stage, 6,7-11,12yr) • 形式運思期(formal operational stage, 11,12yr-)
Vygotsky’s sociocultural perspective (一)Four interrelated levels of analysis #個體發展(Ontogenetic development) #極小發展(Microgenetic development: changes that occur over relatively brief periods of time) #物種發展(Phylogenetic development) #社會歷史發展(Sociohistoricaldevelopment)
(二)重要概念 (1)智能適應的工具 (Tools of intellectual adaptation) elementary mental function 透過社會文化的轉換,包括: (1) how to think:傳遞Tools of intellectual adaptation(在和他人互動中,內 化思考的方法和解決問題的策略) (2) what to think:傳遞社會文化中的信念和價值 higher mental function
(2)最佳發展區(The zone of proximal development )(ZPD) 個體可獨力完成task 這個範圍即是學習發生之所在 促進認知發展的社會互動之特徵: scaffolding guided participation task太困難而無法獨力完成,但可藉由成人 或熟練的同儕之協助而完成
鷹架(Scaffolding) 在教導的情境中,依據孩子現有的表現水準,來調整所提供的支持與協助(在學習情境中,專家對於新手的學習予以指導或反應,而新手藉此慢慢的增加對問題的瞭解) 指導參與(Guided participation) 孩子參與文化活動,而文化活動中有技巧較熟練的大人,透過參與、觀察大人而學習
General models of information processing (一)The store model Longterm memory Response generator Working memory attention Strategy & retrieval Sensory register Central executive Coordination of information Control attention Select, apply & monitor strategies
(二)Connectionism • 發展認知神經科學 • 當熟練新技巧的過程中,大腦確實發生什麼過程 • 運用電腦設計connectionist, or artificial neural network, models
input ooutput Output unit (generate response) Hidden unit (represent) Input unit (encode)
social cognition development • social cognition: • 對社會(自我、他人、關係)的知識或思考 Relation SELF OTHERS
Knowledge about Self • Self recognition • Self concept • Self esteem • Self identity
Knowledge about others Perspective taking or role taking • Perceptual perspective taking • Cognitive perspective taking • Affective perspective taking & empathy
Knowledge about social relationships • Conflict understanding • Moral reasoning • Prosocial moral reasoning • Fairness • Friendship
兒童心智論(children’s theory of mind) • 瞭解人具有一些心智狀態,像是信念、動機、感覺、和意圖等,這些狀態導引個人的行為,且他人不一定知道
Mental states desires emotion action beliefs intentions
Social development • Aggression • Prosocial behavior • Social competence • Interpersonal problem solving
The structure of working memory • Baddeley: tripartite working model: • Three components: Central executive Coordination of information Control attention Select, apply & monitor strategies Working memory: Phonological loop: phonological store and rehearsal processes; Visuospatial sketchpad: visual store and spatial control processes
