+.86
Prenatal Development
-A zygote is a fertilized cell with 100 cells, which become increasingly diverse. At about 14 days the zygote turns into an embryo. -At 9 weeks an embryo turns into a fetus (c and d). Teratogens are chemicals or viruses that can enter the placenta and harm the developing fetus.
Brain Maturation
-Birth to 3 yrs: Branching neural networks enable walking, talking, and remembering. -3 to 6 yrs: Frontal lobes develop, enabling rational planning. -6-13 yrs : Association areas proliferate, enriching thinking, memory, language and reading skills.
Bias in Intelligence Testing
-Critics argue that intelligence tests reflect cultural knowledge and values of dominan cultures, leading to lower scores among minority groups. -Stereotype threat can lower test scores in people who are aware that they belong to negatively viewed groups.
Controversies about Intelligence
-Is intelligence a single overall ability or several specific abilities? -With modern neuroscience techniques can we locate and measure intelligence within the brain?
Gender Similarities and Differences
-Male and female average scores for overall intelligenceare nearly identical. -Gender differences have been demonstrated in specificabilities (females better at verbal memory, males at spatial abilities). -Researchers cite evolutionary, brain-based, cultural explanations for gender differences.
Ethnic Similarities and Differences
-Racial groups differ in their average intelligence scores. -High-scoring people (and groups) are more likely to attain high levels of education and income.

Crystallized
David Wechsler

Environmental Effects
Differences in intelligence among these groups is largely environmental, as if one environment was more fertile to develop these abilities than another.
Sandra has been told that her infant has an extra chromosome 21 in his genetic makeup. This suggests that the infant will suffer from _____.
Down syndrome
Frontal Cortex
During adolescence neurons in the frontal cortex grow myelin which speeds up nerve conduction. Frontal cortex lags behind limbic system development. Hormonal surges and limbic system may explain teens' occasional impulsiveness.
Maturation and Infant Memory
Earliest age of conscious memory is around 3½ years (Bauer, 2002). A 5-year-old has a sense of self and an increased long-term memory, thus organization of memory is different from 3-4 years.
Early Intervention Effects
Early neglect from caregivers leads children to develop a lack personal control over the environment and also impoverishes their intelligence.
Emerging Adulthood
Emerging adulthood spans from 18-25 years. During this time young adults live with their parents and aPend college or work. They marry on average in their mid-twenties.
_____ conditions can override genetic influences on cognitive development, especially among children raised in poverty.

Flynn effect.
Piaget Stage 4:
Formal Operational (12 yrs - Adulthood) -People can solve nonphysical problems; they can think logically about abstract concepts
Howard Gardner
Gardner proposes eight types of intelligences and speculates about a ninth one — existential intelligence — the ability to ponder about question of life, death and existence. Linguistic, Logical-Mathematical, Spatial, Bodily-kinestetic, Intrapersonal (Self), Interpersonal (others), Naturalist.
The existence of savant syndrome seems to support
Gardner's theory of multiple intelligences.
Mental Retardation
Mentally retarded individuals required constant supervision a few decades ago, but with supportive family environment and special education can now care for themselves.
Visual Abilities: What do newborns like to look at?
Mostly: -Angles -Contrasts (Especially black and white) -Eyes/Faces -Primary Colors -Circles/Bullseyes

People with savant syndrome excel in abilities not related to general intelligence.
Theory of mind
People's ideas about their own and others' mental states—about their feelings, perceptions, and thoughts, and the behaviors these might predict.
Emotional Intelligence: Components

Cognitive Development
Piaget believed that the driving force behind intellectual development is our biological development amidst experiences with the environment. Our cognitive development is shaped by errors we make.
Egocentrism
Piaget concluded that preschool children are egocentric. They cannot perceive things from another's point of view.
Secure Attachment
Placed in a strange situation, 60% children express secure aPachment, i.e., they explore their environment happily in the presence of their mothers. When mother leaves they show distress.
Piaget Stage 2:
Preoperational (2 - 7 yrs): -Children have a preliminary understanding of the physical world.

Is Intelligence Neurologically Measurable?
Recent Studies indicate some correlation (about +. 40) between brain size and intelligence. As brain size decreases with age, scores on verbal intelligence also decrease.
Environmental Influences
Recent research has identified chromosomal regions important to intelligence and specific genes that appear to influence intelligence..
The Stanford-Binet, the Wechsler Adult Intelligence Scale, and the Wechsler Intelligence Scale for Children yield consistent results, for example on retesting. In other words, these tests have high

Schemas
Schemas are mental molds into which we pour our experiences.
Schooling Effects
Schooling is an intervention that pays dividends, reflected in intelligence scores. Increased schooling is related to higher intelligence scores.
Self-Concept

Normal Curve
Standardized tests establish a normal distribution of scores on a tested population — a bell-shaped pattern called the normal curve.
_______ ______ can lead to poor performance on tests by undermining test-takers' belief that they can do well on the test.
Stereotype threat
Robert Sternberg
Sternberg (1985, 1999, 2003) also agrees with Gardner, but suggests three intelligences rather than eight. 1. Analytical Intelligence: Assessed by intelligence tests. 2. Creative Intelligence: Intelligence that makes us adapt to novel situations, generating novel ideas. 3. Practical Intelligence: Intelligence required for everyday tasks (e.g. street smart).
Brain Function
Studies of brain functioning show that people who score high on intelligence tests perceive stimuli faster, retrieve information from memory quickly, and show faster brain response times.
Genetic Influences
Studies of twins, family members and adopted children together support the idea that there is a significant genetic contribution to intelligence.
Sherry's brother is considering adopting an infant from an orphanage that has a reputation for minimal child-caregiver interaction. A 1-year-old boy is available for adoption, but he is passive and not speaking yet. What advice would Sherry give her brother?
The chances are good that the boy will learn to talk if he is provided with responsive caregiving.

Heritability
The percentage of variation within a given population that is due to heredity • Currently, the heritability of intelligence for the general population is estimated at approximately 50 percent.
Assimilation and Accommodation
The process of assimilation involves incorporating new experiences into our current understanding (schema). The process of adjusting a schema and modifying it is called accommodation.
