|
hight, weight, intelligence, and personality - effected by multiple genes
|
|
Genotype
|
person's genetic inheritance
|
|
Phenotype
|
observed characteristics, attributed to a combination of heredity and environment.
What is actually observed |
|
Critical Period
|
specific, predetermined period of time during biological maturaion when an organism is particularly snesitive to certain stiumuli tht can have either a postive or negative impact on development. Lorenze with imprinting ...Humans it's attachment and language
|
|
Sensitive Period (critical period)
|
for humans - but they are longer and more flexible than critical periods and are not tied closely to chronological age or maturational stage.
|
|
Three stages of Prenatal Development
|
1) Zygote
2) Embryonic stage - third week through the eight week 3) fetal stage beigins at onset of ninth week continues until birth |
|

|
Dominant vs Recessive Genes disorders
Phenylketonuria (PKU) |

Disorders Due to a Chromosomal Abnormality
2 types |
1 - variation in the number o fchromosomes and 2) an alteration in the structure of chromosomes
|
|
Variation in Chromosomal Number
|
Down Syndrome - autosomal disorder etra chromosome 21. Klinefelter and Turners syndrome are both casued by an abnormality in number of sex chromoslne
|
|
Alterations in Chromosome Structure
deleteions, traslocations, and inversions |
deletions, transolocations, and inversions. Deletions occur when a part of a chromosome is missing. Prader-Willie - missing chromosome - obse, obsessive-compulsive, mental retardation.
Translocation is the transfer of a chromosome segment to another chromosome. Inversion - chromosome breaks into two places. |
|
Teratogens
|
subsrances that cross the placental barrier and cause defects in the embryo
|
|
Teratogen effects of Alcohol
|
fetal alcohol syndrome - risk high when drinking is heavy everyday during pregnancy or engages in binge drinking early in early stages.
Facial abnormalities, visual and hearing impairments, mental retardation, learning disablities, and behaviorl problems (impulsivity, social withdrawel). FAS vs FAE - syndrom vs. effects. with effects are less likely to have facial abnormalities and mental retardation. Fetal alchl spectrum disorder is not often used to desccribe that range. |

|
|
Chronic Illness in children
|
higher risk for internaizing and externalizing symptoms, although most do not actually meet the criteria for a formal DSM diangois.
