obesity
answer
body weight more than 20% higher than the average weight for a person of a given age and height
question
brain lateralization p.428
answer
The two halves of the brain also begin to become increasingly differentiated and specialized. Lateralization, the process in which certain functions are located more in one hemisphere than the other, becomes more pronounced during the preschool year.
question
myelin
answer
protective insulation that surrounds parts of neuron increases which speeds the transmission of electrical impulses along brain cells but also adds to brain weight. This rapid brain growth not only allows for increased cognitive abilities, but also helps in the development of more sophisticated fine and gross motor skills

question
corpus callosum
answer
a bundle of nerve fibers that connects the two hemispheres of the brain, becomes considerably thicker, developing as many as 800 million individual fibers that help coordinate brain functioning between the two hemispheres.
question
malnourished children
answer
children who are malnourished show delays in brain development. For example, severely malnourished children develop less myelinization protecting their neurons
question
brain lateralization Left hemisphere p.428
answer
left hemisphere is involved primarily with tasks that necessitate verbal competence, such as speaking, reading, thinking, and reasoning. Also, the left hemisphere processes information sequentially, one piece of data at a time.
question
brain lateralization Right hemisphere p.428
answer
develops its own strengths, especially in nonverbal areas such as comprehension of spatial relationships, recognition of patterns and drawings, music, and emotional expression. Also, the right hemisphere processes information in a more global manner, reflecting on it as a whole.
question
brain lateralization; Individual & cultural differences p.429
answer
For example, many of the 10% of people who are left-handed or ambidextrous have language centered in their right hemispheres or have no specific language center.
question
brain lateralization; Gender and culture.
answer
Starting 1st year of life and thru the preschool years, boys and girls show some hemispheric differences associated with lower body reflexes and the processing of auditory information.
question
brain lateralization; Lateralization of language
answer
Boys also clearly tend to show greater lateralization of language in the left hemisphere. Females, language is more evenly divided between the two hemispheres. Girls' language development proceeds at a more rapid pace during the preschool years than boys' language development.
question
Simon Baron-Cohen, Psychologist p.429
answer
He argues autistic children (predominately males) have an "extreme male brain." The extreme male brain, though relatively good at systematically sorting out the world, is poor at understanding the emotions of others and experiencing empathy for others' feelings. Baron-Cohen states individuals with an extreme male brain have traits associated with the normal male brain, but display the traits to such an extent that their behavior is viewed as autistic.
question
Brain growth p.429
answer
Grows at faster rate than any other part of the body Increase in interconnections among cells and myelin Corpus callosum becomes thicker Lateralization improves
question
Physical growth
answer
By age 2, the average child in the United States weighs around 25 to 30 pounds and is close to 36 inches tall—around half the height of the average adult. Children grow steadily during the preschool period, and by the time they are 6 years old, they weigh, on average, about 46 pounds and stand 46 inches tall.
question
Individual differences; Height vs Weight
answer
Averages mask individual differences: For instance, 10 percent of 6-year-olds weigh 55 pounds or more, and 10 percent weigh 36 pounds or less. Furthermore, average differences in height and weight between boys and girls increase during the preschool years. Although at age 2 the differences are relatively small, during the preschool years boys start becoming taller and heavier, on average, than girls. Profound differences in height and weight between children in economically developed countries and those in developing countries.
question
Myelination of the reticular formation p.430
answer
In area of the brain associated with attention and concentration and is completed by the time children are about five. May be associated with children's growing attention spans as they approach school age. The improvement in memory that occurs during the preschool years may also be associated with myelination. During the preschool years, myelination is completed in the hippocampus, an area associated with memory.
question
Growing brain
answer
Two-year-olds have brains that are about three-quarters the size and weight of an adult brain. By age 5, children's brains weigh 90 percent of average adult brain weight. In comparison, the average 5-year-old's total body weight is just 30 percent of average adult body weight. Interconnections allow for more complex communication between neurons, and they permit the rapid growth of cognitive skills that we'll discuss later in the chapter. Corpus callosum, a bundle of nerve fibers that connect the two hemispheres of the brain, becomes considerably thicker, developing as many as 800 million individual fibers that help coordinate brain functioning between the two hemispheres.
question
PIAGET- A Quick Review
answer
Knowledge is product of direct motor behavior All children pass through series of stages Universal Fixed order
question
What does Piaget tell us?
answer
Quantity and quality of knowledge changes Focus on change in children's understanding
question
Piaget; Preoperational Stage
answer
Time of stability and change; lack use of operations and organized, formal mental processes Use of operations at end of stage; 2-7 years Characterized by symbolic thinking; mental reasoning and use of concepts increase Still not capable of operations: organized, formal, logical mental processes that characterize school age children. It is only at the end of preoperational stage that the ability to carry out operations comes into play.
question
Piaget; The Relation btw Language & Thought.
answer
Symbolic function: Ability to use symbols, words, or object to represent something that is not physically present Language allows preschoolers to: Represent actions symbolically Think beyond present to future Consider several possibilities at same time Symbolic function is at the heart of one of the major advances that occurs in the preoperational period: the increasingly sophisticated use of language. Use of symbolic thought, allows preschoolers to represent actions symbolically, permitting much greater speed.
question
Piaget; Centration
answer
Centration is the process of concentrating on one limited aspect of a stimulus and ignoring other aspects. Preschoolers are unable to consider all available information about a stimulus. Instead, they focus on superficial, obvious elements that are within their sight. These external elements come to dominate preschoolers' thinking, leading to inaccuracy in thought.
question
Piaget; Incomplete Understanding of Transformation
answer
Preoperational children Unable to envision successive transformations Ignore middle steps Transformation is the process in which one state is changed into another. Adults know that if a pencil that is held upright is allowed to fall down, it passes through a series of successive stages until it reaches its final, horizontal resting spot. In contrast, children in the preoperational period are unable to envision or recall the successive transformations that the pencil followed in moving from the upright to the horizontal position. If asked to reproduce the sequence in a drawing, they draw the pencil upright and lying down, with nothing in between. Basically, they ignore the intermediate steps.
question
Piaget; Egocentrism
answer
Preschoolers do not understand that others have different perspectives from their own Egocentric thought takes two forms Lack of awareness that others see things from a different physical perspective Failure to realize that others may hold thoughts, feelings, and points of view that differ from theirs
question
Piaget; Egocentric Thought
answer
Egocentric thought is thinking that does not take into account the viewpoints of others. Preschoolers do not understand that others have different perspectives from their own. Egocentric thought takes two forms: the lack of awareness that others see things from a different physical perspective and the failure to realize that others may hold thoughts, feelings, and points of view that differ from theirs. Egocentrism lies at heart of several types of behavior during the preoperational period. Preschoolers may talk to themselves, even in the presence of others, and at times they simply ignore what others are telling them. Rather than being a sign of eccentricity, such behavior illustrates the egocentric nature of preoperational children's thinking: the lack of awareness that their behavior acts as a trigger to others' reactions and responses. Consequently, a considerable amount of verbal behavior on the part of preschoolers has no social motivation behind it but is meant for the preschoolers' own consumption.
question
Piaget; Emergence of Intuitive Thought
answer
-Curiosity blossoms and answers to wide variety of questions sought -Often act as authorities on particular topics -Leads preschoolers to believe that they know answers to all kinds of questions, but there is little or no logical basis for this confidence Some highlight "deficiencies" during this period, actually time of considerable cognitive development intuitive thought Intuitive thought refers to preschoolers' use of primitive reasoning and their avid acquisition of knowledge about the world. Often act as authorities on particular topics, feeling certain that they have the correct—and final—word on an issue. If pressed, they are unable to explain how they know what they know. In other words, their intuitive thought leads them to believe that they know answers to all kinds of questions, but there is little or no logical basis for this confidence in their understanding of the way the world operates.
question
Piaget; Late Stages of Intuitive Thought
answer
-Slowly certain qualities prepare children for more sophisticated forms of reasoning -Begin to understand the notion of functionality -Begin to show an awareness of the concept of identity Functionality, the idea that actions, events, and outcomes are related to one another in fixed patterns. Identity is the understanding that certain things stay the same, regardless of changes in shape, size, and appearance.
question
Piaget's Approach Evaluation
answer
Positive: Masterful observer Useful way to consider progressive advances in child cognition Negative: More recent experimental work suggests higher child performance on tasks involving conservation, reversibility, transformation, and ability to count Contentions about continuity of development as theorized in Piaget's stages Actually, broad outlines of his approach has given us a useful way of thinking about the progressive advances in cognitive ability that occur during the preschool years.
question
Information Processing Approaches to Cognitive Dev; Approaches
answer
Focus of Approaches; Changes in kinds of "mental programs" that children use when approaching problems Changes analogous to way computer program becomes more sophisticated as a programmer modifies it on basis of experience Often Used Research Approaches; Understanding number & Memory development
question
Information Processing Approaches to Cognitive Dev.; Preschoolers Understanding of Nos.
answer
Suggest that preschoolers follow a number of principles in their counting. They know they should assign just one number to each item and that each item should be counted only once. Preschoolers may demonstrate a surprisingly sophisticated understanding of numbers, although their understanding is not totally precise. By age 4, most are able to carry out simple addition and subtraction problems by counting and they are able to compare different quantities quite successfully.
question
Information Processing Approaches to Cognitive Dev; Memory: Recalling the Past.
answer
Recollections of events are sometimes, but not always, accurate Typically accurate in responses to open-ended questions Partly determined by how soon memories are assessed Affected by cultural factors. Autobiographical memory; Largely inaccurate before age 3 Not all last into later life. Autobiographical memory, memory of particular events from one's own life, achieves little accuracy until after 3 years of age. Accuracy then increases gradually and slowly throughout the preschool years. Memories are also affected by cultural factors. For example, Chinese college students' memories of early childhood are more likely to be unemotional and reflect activities involving social roles, such as working in their family's store, whereas Australian college students' earliest memories are more emotionally-elaborate and focus on specific events such as the birth of a sibling.
question
Information Processing Theories in Perspective;Why are some preschool memories inaccurate?
answer
Preschoolers' memories of familiar events often organized in terms of scripts, broad representations in memory of events and the order in which they occur. With age, the scripts become more elaborate: getting in the car, being seated at the restaurant, choosing food, ordering, waiting for the meal to come, eating, ordering dessert, and paying for the food. Because events that are frequently repeated tend to be melded into scripts, particular instances of a scripted event are recalled with less accuracy than those that are unscripted in memory.
question
Information Processing Theories in Perspective; Any other causes of memory inaccuracy?
answer
Difficulty describing certain kinds of information, such as complex causal relationships, may oversimplify recollections.
question
Information Processing in Perspective
answer
PRO: Relies on well-defined testable, processes which alternative approaches traditionally have paid little attention. Provides a clear, logical, and full account of cognitive dev. CON: Focuses on series of single, individual cognitive processes. Individual sequence of processes never adequately paint whole, comprehensive picture of cognitive dev.
question
Information Processing in Perspective; Summary
answer
Summary: According to information-processing approaches, cognitive development consists of gradual improvements in the ways people perceive, understand, and remember information. With age and practice, preschoolers process information more efficiently and with greater sophistication, and they are able to handle increasingly complex problems. Developmentalists using information-processing approaches respond to such criticisms by saying that their model of cognitive development has the advantage of being precisely stated and capable of leading to testable hypotheses. They also argue that there is far more research supporting their approach than there is for alternative theories of cognitive development. In short, they suggest that their approach provides a more accurate account than any other.
question
Vygotsky's View of Cognitive Development
answer
Cognition result of social interactions in which children learn through guided participation. Children gradually grow intellectually and begin to function on their own because of assistance that adult and peer partners provide. Vygotsky saw children as apprentices, learning cognitive strategies and other skills from adult and peer mentors who not only present new ways of doing things, but also provide assistance, instruction, and motivation. Consequently, he focused on the child's social and cultural world as the source of cognitive development. According to Vygotsky, children gradually grow intellectually and begin to function on their own because of the assistance that adult and peer partners provide. Focus on child's social and cultural world as source of cognitive development.
question
Vygotsky; Culture and Gender Influences
answer
Nature of the partnership between developing children and adults and peers determined largely by cultural and societal factors. Societal expectations about gender play role in how children come to understand world.
question
Vygotsky; Zone of Proximal Development
answer
Cognition increases through exposure to information that is new enough to be intriguing, but not too difficult Greater improvement with help = greater increases in zone of proximal development Zone of proximal development, or ZPD, the level at which a child can almost, but not fully, perform a task independently, but can do so with the assistance of someone more competent. When appropriate instruction is offered within the zone of proximal development, children are able to increase their understanding and master new tasks.
question
Vygotsky; Scaffolding
answer
Scaffolding is the support for learning and problem solving that encourages independence and growth. Aids in development of overall cognitive abilities.
question
Vygotsky; Cultural Tools
answer
The nature of the tools available to children to solve problems and perform tasks is highly dependent on the culture in which they live: -Actual, physical items or intellectual and conceptual framework for solving problems -Language -Alphabetical and numbering schemes -Mathematical and scientific systems -Religious systems
question
Vygotsky's Perspective Assessment; Broad concepts such as the zone of proximal development are not precise, and they do not always lend themselves to experimental tests.
answer
PRO: Increasingly influential in the last decade. Helps explain growing body of research about importance of social interaction in promoting cognitive development. Consistent with growing body of multicultural and cross-cultural research. CON: Lack of precision in conceptualization of cognitive growth Sparse information about attention and memory develop and how children's natural cognitive capabilities unfold

____ believed that children develop cognitively within a context of ____ and society. His theory includes the concepts of the zone of proximal development and ____.
answer
Vygotsky; culture; scaffolding
question
The Growth of Language and Learning; Language Development; Syntax.
answer
During preschool years: Sentence length increases at a steady pace Syntax doubles each month Enormous leaps in number of words used through fast mapping During the preschool years, children's language skills reach new heights of sophistication. They begin the period with reasonable linguistic capabilities, although with significant gaps in both comprehension and production. Language blooms so rapidly between the late twos and the mid-threes that researchers have yet to understand the exact pattern. Syntax is ways in which children at this age combine words and phrases to form sentences.
question
What is fast mapping?
answer
Fast mapping; in which new words are associated with their meaning after only a brief encounter. New words are associated with their meaning after only brief encounter By age 6, the average child has a vocabulary of around 14,000 words Vocabulary acquired at rate of nearly one new word every 2 hours, 24 hours a day
question
Preschool Language on the Grow
answer
Use plurals and possessive forms of nouns Employ the past tense Use articles Ask, and answer, complex questions Extend appropriate formation of words to new words By the age of 3, preschoolers routinely use plurals and possessive forms of nouns (such as "boys" and "boy's"), employ the past tense (adding "-ed" at the end of words), and use articles ("the" and "a"). They can ask, and answer, complex questions ("Where did you say my book is?" and "Those are trucks, aren't they?").
question
Grammar
answer
Grammar is the system of rules that determine how our thoughts can be expressed. Preschoolers also learn what cannot be said as they acquire principles of grammar Although they still make frequent mistakes, 3-year-olds follow principles of grammar most of time and are correct in their grammatical constructions more than 90 percent of time
question
Private speech
answer
Private speech, originally termed egocentric speech (Vygotsky, 1962/ 1934), is speech that is self-directed and used for the purpose of emotional, psychological, and behavioral regulation. It is traditionally studied in children because private speech is externally voiced until around age 8, after which point it becomes internalized (Diaz & Lowe, 1987). However, people continue to use private speech through adolescence and into adulthood as a means of self-regulation (John-Steiner, 1992). Researchers have distinguished between three kinds of private speech (Berk, 1986): task-irrelevant (e.g., thinking about what to cook for dinner); task-relevant, non-facilitative (e.g., thinking about how frustrating the task at hand is); and task-relevant, facilitative (e.g., figuring out how to best solve a problem). In children, these different kinds of private speech predict performance on tasks, emotional adjustment, and reactions to challenging situations (Manning, White, & Daugherty, 1994).
question
Pragmatics
answer
What about practical communication? Relates to communicating effectively and appropriately with others Helps children to understand the basics of conversations Turn-taking Sticking to a topic What should and should not be said, according to the conventions of society Use of different language in various settings
question
Social Speech
answer
Before the age of 3: Speak only for their own entertainment Apparently unaware if anyone else can understand During preschool years: Begin to direct their speech to others Want others to listen Become frustrated when they cannot make themselves understood Begin to adapt their speech to others through pragmatics Piaget contended that most speech during the preoperational period was egocentric: Preschoolers were seen as taking little account of the effect their speech was having on others. However, more recent experimental evidence suggests that children are somewhat more adept in taking others into account than Piaget initially suggested.
question
How Living in Poverty Affects Language Dev.
answer
Heard home language has profound implications for future cognitive success Hart and Todd Risley (1995) landmark study Affluence of the parents = more speech to children. Parents professionals spent almost twice as much time interacting Children in families that received welfare assistance exposed to fewer words Language used home differed among various types of families. (See Figure 7.12 for complete comparison). The greater the affluence of the parents, the more they spoke to their children. The rate at which language was addressed to children varied significantly according to the economic level of the family. The greater the affluence of the parents, the more they spoke to their children. In a typical hour, parents classified as professionals spent almost twice as much time interacting with their children as parents who received welfare assistance. By the age of 4, children in families that received welfare assistance were likely to have been exposed to some 13 million fewer words than those in families classified as professionals. The kind of language used in the home differed among the various types of families. Children in families that received welfare assistance were apt to hear prohibitions ("no" or "stop," for example) twice as frequently as those in families classified as professionals.
question
How Living in Poverty Affects Language Dev; What these findings suggest...
answer
-Importance of early exposure to language -Usefulness of intervention programs -Consequences for children's general cognitive development & behavior related to poverty & family income. Cannot be interpreted in terms of cause-and-effect, but clearly suggest importance of early exposure to language. Intervention programs may be useful in alleviating some of the potentially damaging consequences of poverty. Family income and poverty have powerful consequences for children's general cognitive development and behavior. Poverty not only reduces the educational resources available to children, it also has such negative effects on parents that it limits the psychological support they can provide their families. In short, the consequences of poverty are severe, and they linger.
question
In the preschool years, children rapidly increase in ____, developing an improved sense of grammar and shifting gradually from ____ to ____ speech.

question
Physical and Cognitive Development in the Middle Childhood Years; Intellectual Development
answer
What are advances and limitations, in thinking during childhood? Approaches: Piaget Information-processing Vygotsky
question
Physical and Cognitive Development in the Middle Childhood Years; Intellectual Development: Piaget
answer
Concrete operational stage 7 and 12 years Characterized by active and appropriate use of logic Logical operations applied to concrete problems Conservation problems; reversibility; time and speed, decentering
question
Physical and Cognitive Development in the Middle Childhood Years; How slow can you go?
answer
Children still experience one critical limitation in their thinking. They remain tied to concrete, physical reality. Furthermore, they are unable to understand truly abstract or hypothetical questions, or ones that involve formal logic, such as concepts like free will or determinism.
question
Physical and Cognitive Development in the Middle Childhood Years; From preoperational thought to concrete operational thought?
answer
Shift from preoperational thought to concrete operational thought does not happen overnight Children shift back and forth between preoperational and concrete operational thinking Once concrete operational thinking is fully engaged, children show several cognitive advances They attain the concept of reversibility, which is the notion that processes transforming a stimulus can be reversed, returning it to its original form. Because they are less egocentric, they can take multiple aspects of a situation into account, an ability known as "decentering."
question
Physical and Cognitive Development in the Middle Childhood Years; Piaget Was Right...Piaget Was Wrong!?
answer
Right! Virtuoso observer of children Powerful theoretical, educational implications Wrong? Underestimate of children's capabilities, in part because of the limited nature of mini-experiments conducted Misjudged age at which children's cognitive abilities emerge Neglected cross-cultural differences Many schools still employ principles derived from his views to guide the nature and presentation of instructional materials!
question
Physical and Cognitive Development in the Middle Childhood Years; Information Processing:
answer
Information Processing: Increasing ability to handle information Memory improvement Short term memory capacity improvement Memory in the information-processing model is the ability to encode, store, and retrieve information. Memory capacity may shed light on another issue in cognitive development. Some developmental psychologists suggest that the difficulty children experience in solving conservation problems during the preschool period may stem from memory limitations.
question
Physical and Cognitive Development in the Middle Childhood Years; Thinking about Memory: Metamemory
answer
Understanding about processes that underlie memory Improves during school age years Helps children use control strategies (conscious, intentional tactics to improve functioning)
question
Physical and Cognitive Development in the Middle Childhood Years;Can children be trained to be more effective in use of control strategies?
answer
School-age children can be taught to use particular strategies Keyword strategies See Center for Development and Learning (10 Strategies to Enhance Memory) for additional strategies Keyword strategy;1 word is paired with another that sounds like it. http://www.cdl.org/resourcelibrary/articles/memory_strategies_May06.php?type=recent&id=Yes
question
Physical and Cognitive Development in the Middle Childhood Years; Vygotsky's Approach
answer
Cognitive advances occur through exposure to information within zone of proximal development (ZPD) Influential in development of classroom practices Cooperative learning Reciprocal teaching The ZPD is the level at which a child can almost, but not quite, understand or perform a task. WHAT IS IT? Cooperative learning is a successful teaching strategy in which small teams, each with students of different levels of ability, use a variety of learning activities to improve their understanding of a subject. Each member of a team is responsible not only for learning what is taught but also for helping teammates learn, thus creating an atmosphere of achievement. WHY USE IT? Documented results include improved academic achievement, improved behavior and attendance, increased self-confidence and motivation, and increased liking of school and classmates. Cooperative learning is also relatively easy to implement and is inexpensive. WHAT IS IT? Reciprocal teaching refers to an instructional activity that takes place in the form of a dialogue between teachers and students regarding segments of text. The dialogue is structured by the use of four strategies: summarizing, question generating, clarifying, and predicting. The teacher and students take turns assuming the role of teacher in leading this dialogue.
question
Physical and Cognitive Development in the Middle Childhood Years; Language Development: What Words Mean
answer
Mastering the Mechanics of Language in Middle Childhood: Vocabulary continues to increase Mastery of grammar improves Understanding of syntax grows Certain phonemes remain troublesome Decoding difficulties when dependent on intonation More competence in pragmatics Increase in meta-linguistic awareness VOCABULARY DEVELOPMENT: happens quite naturally through exposure to vocabulary-rich literature selections, always teaching "the language of instruction" (what every word used by the teacher in her daily teaching tasks means), by listening to the teacher "model" good speech and interesting sentences with the spelling dictation, AND by the specific teaching of the meanings of prefixes, roots and suffixes. GRAMMAR: Children and Grammar. Linguists' view of language and grammar; grammar is special; grammar is separate; grammar must be innate. Assertions about early grammar acquisition: Grammatical elements are innate; Syntactic rules are used in early "sentences;" Grammar learning is implicit. -Semantics, Grammar, Lexicon, Rules: Semantics = meaning of morphemes and words. Syntax = grammar conveyed through word order. Grammar = syntax + inflectional morphology. Two ways linguistic information stored: Lexicon = individual "words" & information; Rules = generalized procedures. -Linguists view of grammar Two types of grammatical information: categories in lexicon; terminal elements (e.g. N, V), non-terminal elements (e.g. NP, VP); "rewrite" rules Grammar = arranging elements using rules; Semantics is irrelevant. -Separate modules & grammar first conflict btw psychologists & linguists Chomsky (1959) demolished behaviourism: language is unpredictable; language is creative. Use a special kind of rule: requires competence-performance distinction; Gold's theorem - language unlearnable. Psychologists - initially sort evidence support linguists' claims, but increasing conflict. Grammar acquisition: Examine 2{two} proposals which arose from the linguistic perspective: Grammatical elements are innate. Syntactic rules are used in early "sentences". Origin of grammatical elements: mantic bootstrapping theory Pinker (1984): grammatical elements are innate; grammar acquisition involves mapping words onto these elements . Mapping achieved via semantics: -learn very general semantic categories = thematic roles (e.g. theme, goal); - innate linking rules maps roles to elements. Origin of grammatical elements: Semantic bootstrapping theory?? Bowerman (1990): theory predicts some verbs hard to learn; if theme maps to subject easy (e.g. fall), if elsewhere (e.g. lose) hard; but, acquired at same time. Braine (1988): If learn thematic roles why not grammatical units? - Semantic Assimilation Theory. Origin of grammatical elements: Does semantics come first? Construct grammatical units from semantics Early language is agrammatical. Nouns = things, adjectives = attributes, verbs = actions - but McShane (1991): abstract nouns (e.g. sleep, truth, love); verbs "states" not actions (e.g. want, think, like). Can not be semantic analysis alone (e.g. states are verbs expect "I hungries"). Where do grammatical units come from??? Innate principles are not necessary or even useful. Semantics may also be of little help. Probably learn through patterns in language - syntactic +morphological: (turns Gold's theorem on its head); -false assumptions - e.g. learning is not rule based induction. Early Grammar: Up to three years: language use inflexible (Tomasello, 2000); lexically based around individual verbs (Pine & Lieven, 1997); no grammatical rules - acquisition statistically. No grammar module at birth: context & social factors crucial (Messer, 2000); develops during childhood (e.g. Kim et al., 1997)
question
Physical and Cognitive Development in the Middle Childhood Years; Metalinguistic Awareness.
answer
Metalinguistic awareness is increasing understanding of their own use of language. In early years learn and comprehend these rules implicitly, during middle childhood come to understand them more explicitly Help achieve comprehension when information is fuzzy or incomplete One of most significant developments in middle childhood is children's increasing understanding of their own use of language By age 5 or 6, Understand language is governed by set of rules By age 7 or 8, Realize that miscommunication be due to factors attributable not only to themselves, but to person communicating with them

As children progress into the middle childhood years, however, their self-esteem is higher for some areas and lower in others.

question
Social and Personality Development in Middle Childhood; Viewing the Cycle of Failure
answer
Breaking the Cycle of Failure; Promoting development of self-esteem Using authoritative child-rearing style Why do you think this style is recommended? Because authoritative parents are warm and emotionally supportive, while still setting clear limits for their children's behavior. In contrast, other parenting styles have less positive effects on self-esteem. Parents who are highly punitive and controlling send a message to their children that they are untrustworthy and unable to make good decisions—a message that can undermine children's sense of adequacy. Highly indulgent parents, who indiscriminately praise and reinforce their children regardless of their actual performance, can create a false sense of self-esteem in their children, which ultimately may be just as damaging to children.
question
Social and Personality Development in Middle Childhood; Race and Self-Esteem
answer
Early research found that African Americans had lower self-esteem than whites More recent research shows these early assumptions to be overstated: African Americans Hispanic Americans Asian Americans Set of pioneering studies a generation ago found that African American children shown black and white dolls preferred the white dolls over the black ones (Clark & Clark, 1947). Picture is more complex regarding relative levels of self-esteem between members of different racial and ethnic groups. For example, although white children initially show higher self-esteem than black children, black children begin to show slightly higher self-esteem than white children around the age of 11. This shift occurs as African-American children become more identified with their racial group, develop more complex views of racial identity, and increasingly view the positive aspects of their group membership. Hispanic children, also show an increase in self-esteem toward the end of middle childhood, although even in adolescence their self-esteem still trails that of whites. In contrast, Asian-American children show the opposite pattern: their self-esteem in elementary school is higher than whites and blacks, but by the end childhood, their self-esteem is lower than that of whites.
question
Social and Personality Development in Middle Childhood; Social Identity Theory
answer
Why does this occur? Social Identity Theory: Members of a minority group accept negative views held by majority group only if they perceive little realistic possibility of changing power and status differences between groups If minority group members feel that prejudice and discrimination can be reduced, and they blame society for the prejudice and not themselves, self-esteem should not differ between majority and minority groups. As group pride and ethnic awareness on the part of minority group members has grown, differences in self-esteem between members of different ethnic groups have narrowed.
