Chapter 8: Intelligence
mathematical equality
the concept that the values on each side of the equal sign must be equivalent - isn't developed until much later after the the preschool period
stage 1
- 1st and 2nd grade -children acquire phonological recoding skills
stage 2
- 2nd and 3rd grades - children gain fluency in simple reading material - learn to read
stage 3
- 4th through 8th grade - children become able to acquire new and complex information from print - read to learn
stage 4
- 8th grade to 12th grade - - adolescents acquire skill not only in understanding information presented form a single perspective but also in coordinating multiple perspectives. - makes it able for them to appreciate subtleties in sophisticated literature
Why is that countries in East Asian Finland and the Netherlands have stronger math students than the states?
- One is that in the countries with the highest math achievement, teachers and students spend much more time on mathematics than do their counterparts in the United States - math instruction in these countries is more coherent; that is, it makes clear the relations among the relevant concepts and procedures
environmental risk scale
- a variety of factors in combination contribute to the problem of substantial numbers of children failing to reach their intellectual potential. - the more - the more risks in the child's environment, the lower their IQ - The average IQ of a child who had no risk factors was around 115, average IQ of those with 6 or more risks was 85
what is fluid intelligence closely related to
- ability to learn - speed of information processing - capacity fo working memory - ability to control attention - brain size, particularly areas of the cortex - amount of activation of specific brain areas on tasks that require attention and problem solving
HOME (home observation measurement of the environment)
- allows to measure the correlation between family influences and intelligence. - measure various aspects of a child's home life - designed to assess the home lives of children between birth and the age of 3
Sternberg proposed that the degree to which people succeed in life depends on three types of abilities. What are they?
- analytical (mathematical, linguistic and spatial skills) - practical (reasoning about every day problems) - creative (intellectual flexibility and innovation that allows effective reasoning in novel circumstances)
passive effects of gene-environment relations
- arise when child is raised by their biological parents - occur due to overlap between their genes and their parent's - IQ correlation are higher between biological parents and their children when they with together (vs. adoption)
stage 0
- birth to first grade - children acquire phonological awareness
What can be taught by people with mathematical disabilities later on in life
- can help prove the fact that mathematics is still largely needed after schooling as well in day-to-day life
Evidence that schooling makes you smarter
- children who were even a grade above younger children showed significant increase in scoring (i.e. verbal oddities) - average IQ and achievement test scores drop during the summer and rise during the school year
In what ways can poverty effect the development of intelligence?
- chronic inadequate diet can disrupt brain development - reduced access to health services - inadequate parenting - insufficient intellectual stimulation and emotional support
Whta is the cause of severe mathematical disability
- damage to brain areas like the interaparietal sulcus is often the cause
evocative effects of gene-environment relations
- emerge through children's eliciting or influencing other people's behaviour
genetic contribution to intelligence
- genes have a substantial influence of intelligence, which varies greatly from age - this variation becomes more greater as the child grows older
active effects of gene-environment relations
- involve children choosing environments that they enjoy
Benefits of reading to young children
- learn how stories tend to go - facilitating understandings of new stories - enhances general language development
what does crystallized intelligence reflect/ related to?
- long term memory for prior experiences - related highly to verbal ability
What two things play a huge role in writing
- metacognitive functioning - content knowledge
What are some factors that contribute to increase in phonemic awareness?
- nursery rhymes - growth of working memory - increasingly efficient processing of language and reading
three types of effects in gene-environment relations
- passive effects - evocative effects - active effects
In which two ways can words be retrieved?
- phonological recoding - visual based memory
What are other variables for mathematical disabilities?
- poor working memory capacity for numbers - slow processing of numerical information - anxiety about mathematics
Brazilian street vendor children
- showed great arithmetic capabilities when the context of street vending was used however had difficulty solving the same problem when applied at the academic/ traditional school problem style
What is one striking feature of how young children solve arithmetic problems?
- the variety of strategies they use to solve problems - i.e. counting from the larger addend in the first addend
uncertainty with HOME
- type of intellectual environment that parents establish in the home is almost certainly influenced by their genetic makeup - almost all studies using the HOME method have focused on children living with their biological parents.
sings of gifted children early in life?
- unusual alertness and long attention span in infancy - Rapid language development - Curiosity—asking deep questions and being dissatisfied with superficial answers - High energy levels, often bordering hyperactivity - Intense reactions to frustration -Precocious reading and interest in numbers - Exceptional logical and abstract reasoning - Unusually good memory - Enjoyment of solitary play
average IQ
100
At what age do Intelligence tests have their widest applicability
5-6 years of age
What percent of children are recognized as having mathematical disabilities? Do these children have lower IQs?
5-8% children - not heir IQs are in the normal range
1 standard deviation of the stanford binet IQ test
68th percentile
95% percent of children fall within standard deviations in IQ scores. what is the range?
70-130
2 standard deviations of the stanford binet IQ test
98th percentile
3 standard deviations of the stanford binet IQ test
99th percentile
at least one specialized, intensive program has shown the possibility of producing enduring gains in IQ and school achievement as well. What program is it?
Carolina Abecedarian Project - well-planned, multifaceted program proved to have lasting positive effects on the IQs and achievement levels of children in the experimental group.
three-stratum theory of intelligence
Carroll's model of intelligence, including g at the top of the hierarchy, eight moderately general abilities in the middle, and many specific processes at the bottom
multiple intelligence theory
Gardner's theory of intellect, based on the view that people possess at least eight types of intelligence
according to the three-stratum theory of intelligence, what does the g indicate?
General intelligence influences all of the moderately general abilities, and both general intelligence and the moderately general abilities influence the specific processes
In contrast to Ceci and Sternberg, what do advocates of intelligence tests argue?
Intelligence tests are better than any alternative in predicting outcomes such as school grades, occupational success and results on achievement tests as well as which children need special education.
What are the eight types of intelligence according to Gardner?
Linguistic logical-mathematical spatial musical naturalistic bodily-kinesthetic intrapersonal interpersonal
what is the underlying genetic cause for why adopted children seem to correlate more and more for intelligence with their biological parents rather than their adoptive parents?
One reason for this increasing genetic influence is that some genetic processes do not exert their effects on IQ until later childhood and adolescence or example, some connections linking areas in the brain that are distant from each other are not formed until adolescence, and the extent of such connections reflects genetic influences
preschoolers writing, how is this significant
Preschoolers' "writing" indicates that they expect meaning to be reflected in print.
theory os successful intelligence
Sternberg's theory of intellect, based on the view that intelligence is the ability to achieve success in life
What si the similarity between the theory of two intelligences and the primary mental abilities?
The key evidence for the usefulness of dividing intelligence into these seven abilities is similar to that for the distinction between fluid and crystallized intelligence. Scores on various tests of a single ability tend to correlate more strongly with each other than do scores on tests of any of the other abilities.
results of HOME and intelligence
Throughout childhood, children's IQ scores, as well as their math and reading achievement, are positively correlated with the HOME measure of their family environment - when home scores are relatively stable over time, so is the IQ of the children
standard deviation
a measure of the variability of scores in a distribution; in a normal distribution, 68% of scores fall within 1 standard deviation of the mean and 95% of scores fall within 2 standard deviations
normal distribution
a pattern of data in which scores fall symmetrically around a mean value, with most scores falling close to the mean and fewer and fewer scores farther from it
gesture-speech mathematics
a phenomenon in which hand movements and verbal statements convey different ideas
Pre-K mathematics
a program designed for preschoolers, especially those from low- income families, to prevent mathematics disabilities through exposure to a variety of numerical activities
IQ (intelligence quotient)
a summary measure used to indicate a child's intelligence relative to that of other children of the same age
Wechsler Intelligence Scale for Children (WISC)
a widely used test designed to measure the intelligence of children 6 years and older
phonological porcessing
ability to discriminate and remember sounds within words
phonemic awareness
ability to identify component sounds within words
fluid intelligence
ability to think on the spot to solve novel problems
phonological recoding skills
ability to translate letters into sounds and to blend sounds into words
What si the advantage of viewing intelligence as many things?
allows more precise specification of the processes involved in intelligent behaviour than do approaches that view it as "one thing" or "a few things."
what is the purpose of some many subdivisions of HOME?
assessing varied aspects of a child's family environment allows good prediction of the child's IQ.
1st graders are very skillful in adjusting their strategies to the difficulty of the particular word, why is this?
associative learning- children's past behaviour shapes their future behaviour
intervention programs to support children from low SES proved that the programs had short term effects on increasing IQ, however long term effects in decreasing the number of students who would enter special ed or be held back a grade. Why is this so? and what effects do we see when these children became adults?
because although they didn't raise children's IQ long term, they did increase their motivation and behaviour. - former participants of the program as adults were less likely to be on welfare, and earned larger salaries than non-participants
What is another powerful influence is _________________
content knowledge
Theory of two intelligences?
crystallized intelligence and fluid intelligence
what are the courses of crystallized and fluid intelligence?
crystallized: increases steadily from early life to old age fluid: peaks in early adulthood (around age 20) and steadily declines form there.

mental model
What is especially hard for dyslexics?
determining sounds that go with letters, especially vowels
what two gene-environment relations explain why adopted children have higher correlation in intelligence with their biological parents?
evocative and active
crystallized intelligence
factual knowledge about the world
if preschoolers from poor families were read to daily, this would not have any effect on the quality of reading comprehension because of their low income
false
true or false: adopted children's IQ scores correlate higher to their adoptive parents rather than their biological ones.
false. adopted children's IQ scores correlate higher to their biological parents. The intelligence of adopted children becomes less correlated with their adoptive parents as the child gets older.
true or false: the more years children spend in poverty, the higher their IQs tend to be.
false. the more years children spend in poverty, the lower their IQs tend to be.
true or false: the environment has an immediate but short term risk on a child's intellectual development.
false: the environment has an immediate and long term risk on a child's intellectual development.
Why is that IQ and achievement scores drop for children from low SES and are relatively stable or higher for children from high SES?
fewer children from low-SES families have the kinds of experiences that would maintain or increase their academic achievement that they would have during the school year
8 sub categories of the three stratum of intelligence
fluid intelligence, crystallized intelligence, general memory and learning, broad visual perception, broad auditory perception, broad retrieval ability, broad cognitive speediness, processing speed
top of the three-stratum theory

kindergartener's mastery of letter names is positively correlated with what?
later reading achievement through at least 7th grade, however there is no casual relation
what two things do IQ tests reflect?
mean standard deviation
Critics such as Ceci and Sternberg argue what about intelligence?
measuring a quality as complex and multifaceted as intelligence requires assessing a much broader range of abilities than current intelligence tests include - current Intelligence tests are culturally biased - reducing a person's intelligence to a numerical value is questionably unethical and simplistic.
practical intelligence
mental abilities not measured on IQ tests but important for success in many situations, such as accurately reading other people's emotions and intentions and motivating others to work effectively as a team
Aside from IQ, what are some other factors that can predict long term occupation, academic and economic success?
motivation to succeed, conscientiousness, creativity, physical and mental health, and social skills, characteristics of the environment (parental motivation and encouragement)

stage 0 (birth until the beginning of first grade) stage 1 (1st and 2nd grade) stage 3 (4th through 8th grades) stage 4 (8th though 12th grades)
What is the basis of the two-intelligence theory?
supported by the fact that tests of each type of intelligence correlate more highly with each other than they do with tests of the other type. the two types of development have different developmental courses.

According to Gardner, what is the major flaw with intelligence tests?
the tests asses verbal, mathematical, and spatial capabilities but they do not directly examine other abilities

true.
studies that show that there is a positive correlation between gesture-speech mismatches and subsequent mathematical abilities imply what idea?
variability of thought and action often indicates heightened readiness to learn
Best way for dyslexics to cope?
what seems to work best is to teach children with dyslexia to use strategies that would enhance their phonological recoding
What are the 7 primary mental abilities?
word fluency, verbal meaning, reasoning, spatial visualization, numbering, rote memory, and perceptual speed
is learning to write is a good deal more difficult than learning to read?
yes - because writing requires to simultaneously focus on numerous goals, like forming letters, grammar punctuation, etc.
Is intelligence hard to define?
yes it is, there have been many theories surrounding intelligence
