Outline
1. Piaget's theory of cognitive development and practical implications
2. Information processing theory
3. Overlapping Waves Model
(Robert Siegler)
Thought question:
The HK Law Reform Commission recommends that the age of criminal responsibility be 10 years old. Currently, the age of criminal responsibility is 7 years of age. Is this change justified, given what you learn about cognitive development today? In other words, is 10 years of age too old, too young, or just right?
Stages1) Sensorimotor period (0-2 years)
a)reflexes (0-1 month)
b)primary circular reactions (1-4 months)
c)secondary circular reactions (4-12 months)
--coordination of 2ndary schemes
d)tertiary circular reactions (12-18 months)
e)representational thought (18-24 months)
Stages 2) Preoperational period (2-7 years)
Focus on conservation
Preoperational thought is illogical in the following ways:
a) Centering b) Egocentrism c) Irreversibility
d) Appearance as reality
Suggestions for teaching the preoperational child (Woolfolk,
1995)1. Be concrete
2. Make instructions short and use actions to demonstrate
3. Be sensitive to egocentrism
4. Clarify language
5. Do hands-on learning
Young children's play styles1. Sensorimotor (12 months)
2. Constructive (after 12 months on)
3. First pretend (2nd year)
4. Substitute pretend (2-3 years on)
5. Sociodramatic (2-4 years on)
Stages
3) Concrete operational period (7-12 years) Mastery of reversibility
Inductive logic mastered
Deductive logic poor
4) Formal operational thinking (adolescents and adults)
--Abstract thinking mastered
--If X is correct, y, z, and a
should be observed
(hypothetico-deductive
reasoning)
Facts China/Taiwan=14 Macau=16 HK: schooling until 15 HK: In sexual abuse cases, child=16 or younger Rehabilitation vs. criminalization Nevertheless, recommended age of criminal
responsibility=10; actual legal age of criminal responsibility=7
Critique of Piaget's theory1) Over-focus on language explanations2) Some skills appear earlier than posited
--theory of mind (3-5 years old) --gender constancy (4-5 years old) 3) Variabilities in performance
4) Culture (individualism) --Vygotsky's zone of proximal development
--Scaffolding
Conclusion
First 3 “stages” of cognitive development occurs much more gradually (less stage-like) and earlier than Piaget assumed; adolescents perform less
consistently hypothetico-deductively than originally postulated.
2) Information processing theory
A) Mental hardware--built-in mental and neural structures
- speed - attention - memory
3) Overlapping Waves Model (Siegler)
Assumption of variability, e.g.,
1) Addition
2) Spelling
3) Infant locomotion
4) Conservation
Strategic development depends upon
Acquisition of new strategies Changes in frequency of existing strategies Changes in speed of execution of strategies Changes in accuracy of execution of strategies Changes in range of problems to which each
strategy can be applied
Lessons learned
1) Change is gradual.
2) Discoveries follow success as well as failure.
3) Early variability is related to later learning.
4) Discoveries are constrained by conceptual understanding.
Very early, children --Can distinguish print from pictures and nonprint --Use visual cues to recognize first characters
Better readers are--Faster --Better in language manipulation --Skilled at morphological awareness
Developmental Concepts of Reading:
Phonemic awareness, phonics, letter names, letter sounds (Bee, 2000; Berk, 2003; Feldman, 2004)
To date, developmental textbooks assume that READING=READING ENGLISH

reading
Phonological Awareness Awareness of and access to the sounds in language.
In English, “fisp” without the /s/ is “fip.” In Chinese,
Syllable awareness (e.g., McBride-Chang & Ho, 2000)
Onset-rime (Huang & Hanley, 1995; 1997; Siok & Fletcher, 2001)
Examples of levels of PA Syllable awareness:
大門口 (da4 men2 kou3) 大口 (da4 kou3)
Onset-rime/phonemic awareness: tai-/t/ =ai
Morphological Awareness
Morpheme=smallest unit of meaning
Morphological awareness--Awareness of and access to the meaning structure of language
Simple compounding examples
人 (Ren)
大人 (Adult)
女人 (Woman)
外國人 (Foreigner)
車 (Che)
火車 (Train)
汽車 (Private Car)
Cross-cultural measurement
Chomsky: generativity,creativity, productivity occur across languages
--Plantman for gardener--Clark, 1995
--”Genius comes from genie”
Berko (1958): Wug/wugs; What do you call one who zibs?Why do you think a ___is called a ___?
Our task, across cultures, requires that
Children produce novel words by combining familiar morphemes in new ways, e.g., sunset/moonset; treetop/treebottom.
Examples: 有一種家庭電器可以用來洗衣服,我們叫它洗衣機。 There is home appliance that uses to wash clothes, it is
called a ‘washing machine’. 有一種新的家庭電器可以用來洗鞋,我們會怎麼叫它呢? [ 洗鞋機 ] 。
If that home appliance uses to wash shoes, what would you call that? (washing shoes machine)
有一種動物條頸好長既,叫做長頸鹿。 There is one animal that has a very long neck, we
call that a giraffe. 咁如果呢種動物條頸好短,咁我地會叫佢做咩呢?[短頸鹿 ] 。
If this animal’s neck has been shortened, what would you call that? (Giraffe with short neck)
Cross-Cultural Issues
Evolutionary primary abilities (Geary, 1995)
--phonological awareness, morphological awareness, vocabulary: Language constructs may be “universals.”
Evolutionary secondary abilities (reading) : For reading, it’s all relative.
Cultures included in this study
Beijing--Pinyin and Putonghua Hong Kong--No phonological coding system and
Cantonese S. Korea--Clear phonological structure and much
compounding U.S.--Clear need for phonemic awareness and less
transparent morphological structure
Conclusions Despite similar associations among language-related
constructs, these constructs predict reading differently in different scripts--Morphological is important in Chinese and Korean; phonological awareness is important in English and Korean.
These differences are specifically attributable to differences in scripts (and probably ultimately attributable to language differences as well.
Why should you care?
Theoretically, this theory of early reading growth accounts for observations of reading development across cultures better than do current conceptualizations as found in developmental textbooks.
Theoretically, this theory fits well with notions of evolutionarily primary and secondary skills.
Why else should you care?
This conceptualization suggests that different remediation strategies for those low in reading skills may be in order depending upon culture/script to be learned.
Practical implications: Morphological awareness may be particularly useful to develop and explicitly teach in Chinese and Korean for young children.
