Dominant Gene traits
-will inherit trait whether you inherit the dominant trait from both parents or and one parent
- curly hair, brown eyes, farsightedness and Huntington’s disease
Recessive Gene traits
- due to the inheritance of a pair of recessive genes
- must inherent trait from both parents
- straight hair, Green eyes, color blindness, cystic fibrosis and taysachs disease
Polygenic traits
- most traits
- determined by multiple genes
- height, weight, skin color and temperament
Alleles
- alternate forms of a gene that control a particular trait
Homozygous
- alleles for characteristics are the same
Heterozygous
- alleles for a trait are different
Genotype
- characteristics that are determined by information that’s coded on genes
Phenotype
- observable characteristics that are affected by genetic and environmental factors
- height= can be genetically predisposed to be tall but environmental leads to you being short, due to poor nutrition during childhood
Prater Willi syndrome
- due to deletion on paternal chromosome 15
- distinct physical features: narrow forehead, small hand/beat, almond shaped eyes, short stature
- flaccid mussels, overeating/ obesity, hypergonadism, obsessive compulsive behavior, mental delays, underdeveloped sex organs, learning disabilities, and skin picking
Angelman syndrome
- due to deletion on maternal chromosome 15
- microcephaly, why jaw/pointed chin, severe developmental delays, communication difficulties, stereotypic hand movements, and naturally happy, learning disabilities, hyperactivity, ataxia, and seizures
Down syndrome
- usually due to the presence of an extra number 21. Chromosome
-autosomal
- intellectual disability
- physical features: short stocky build, wide face, thick tongue, almond shaped eyes
- increase risk for heart abnormalities, impaired, vision and hearing and Alzheimer’s
Kleinfelter’s syndrome
- Male
- presence of two or more x chromosomes and 1y chromosome
- develop as a normal male identity with incomplete secondary sex characteristics and often sterile
- disproportedly long legs and arms, taller than normal, language learning and behavioral problems
Turner syndrome
- occurs in females
- only One x chromosome - missing all her part
- failure to develop secondary sex characteristics and infertility
- Short stature, stubby fingers, droopy eyelids, webbed neck, learning disability, vision and hearing impairments, skeletal abnormalities, heart defects, and kidney problems.
Teratogens
_ drugs, disease, or environmental hazard psych cause developmental defects in an embryo or fetus
- effects depend on type of taratogen, amount of exposure, and the time of exposure during prenatal development
- third to 8th week after conception must risky

Fetal alcohol spectrum disorder
- 4 disorders
- most severe is fetal alcohol syndrome
- irreversible
- low birth rate, facial abnormalities: Small eyes, thin upper lip, short nose, slow physical growth, impaired memory/attn, judgment and other cognitive deficits, hyperactivity, impulsivity and other behavior problems, And physical defects that may involve the heart , kidneys, bones, vision and hearing
Dsm diagnosis equals neural behavioral disorder associated with prenatal alcohol exposure (nd-pae)
Neural behavioral disorder associated with prenatal alcohol exposure
- tsm diagnosis for fetal alcohol syndrome
- requires more than minimal exposure to alcohol during gestation
- One or more symptoms of impaired neurocognitive function and one or more symptoms of impaired self-regulation and two or more symptoms of impaired adaptive functioning with the onset of symptoms occurring during childhood
Prenatal exposure to cocaine
- spontaneous abortion during first trimester
- premature birth, low birth weight
- physical defects and intestine heart and kidneys
- irritability, overreactivity to the environmental stimuli, shrill piercing cry, difficult to soothe, attention and memory problems, language delays, learning disabilities and behavior problems
- not clear of some of the problems are due to having a substance abusing parent or the actual effects of the drug
Bronfenbrenner’s ecological theory
- five environmental systems that influence environment
+ Microsystem
+ Meso system
+ Exo system
+ Macro system
+ Chrono system

+ Microsystem
+ Meso system
+ Exo system
+ Macro system
+ Chrono system
Microsystem
- immediate environment
- family, friends, school and neighborhood
Meso system
+ interactions between the components of the microsystem.
Exo system
- parts of the environment that the child is affected by But not in direct contact with
- parents workplace, school board, law enforcement agencies, community health services
Macro system
- sociocultural context in which the other systems are embedded and affect the child’s development
- socioeconomic conditions, cultural values And patterns, religious beliefs and political philosophies

- sociocultural context in which the other systems are embedded and affect the child’s development
- socioeconomic conditions, cultural values And patterns, religious beliefs and political philosophies
Chrono system
- changes and continuities that occur over time
- Life transitions, historical events, biological changes, physiological changes, changes in families economic system due to a recession, parents divorce

Brain
- 25% of adults wait at birth
- areas that control vital functions: respiration, heartbeat, sleep on a Rosa and other vital functions most well developed
- sensory and motor areas less well. Developed: cerebral cortex But mature rapidly soon after birth
+ By age 2 it’s 80 Percent of its adult weight
Perfrontal cortex continues to develop into late teens or early to mid-20s

Perfrontal cortex continues to develop into late teens or early to mid-20s
Neurons at birth
- most are present
- increase in brand size following birth due to growth of new dendrites, synaptogenesis (creation of new synapses)) and myelination of nerve fibers
The brain and aging
- begins gradually shrink due to loss of neurons And accelerates after age 60
- Brain compensates for the loss by developing new synaptic connections and neurogenesis. (Create a new neurons) In the hippocampus and possibly other areas of the brain
Vision
- least developed since at birth
-newborns have Limited visual acuity and see @ 20 ft. With normal adults See 400 to 600 ft
- by 7 to 8 months visual acuity is similar to normal adults
Vision at 1 to 2 months
- newborns prefer facial to non-facial images
- prefer faces of their mothers and other caregivers over faces to strangers by 1 to 2 months
Depth perception development
- sequence of three stages each rely on different depth cues from birth to 9 months of age
- kinetic
- binocular
- pictorial

- kinetic
- binocular

Kinetic depth cues
- begins around 3 weeks of age
- rely on cues based on the movement of objects
Kinetic depth cues
- begins around 3 weeks of age
- rely on cues based on the movement of objects
Binocular depth cues
- 2 to 3 months of age
- using both eyes to judge the distance of objects
Pictorial depth cues
,- 5 to 6 months
- linear perspective, relative size of objects, and texture gradient
First senses to show age-related decline
– vision and hearing
First senses to show age-related decline
– vision and hearing
Vision and aging
- by 40 many have signs of presbyopia( farsightedness), decreased visual acuity and dim light, increase sensitivity to glare, reduced ability to discriminate between colors, and decrease depth perception
Vision after 65
- many have visual impairments and that interfere with Reading, driving, and other aspects of daily life

- many have visual impairments and that interfere with Reading, driving, and other aspects of daily life
Audition in newborns
- only slightly less sensitive than that of an adult
- A few days after birth, prefer human voices two other sounds And prefer mom or other caregivers voice to strangers
- soon after birth exhibit auditory localization( turn heads to follow sound), this ability declines 2 to 4 months then re-emerges and becomes fully developed about 12 months

Audition and aging
- hearing problems begin around age 40
- hearing impairments are more common than visual impairments
- most don’t have significant hearing loss until after 75
Presbycusis
- first sign of hearing impairment
Decrease in the ability to perceive high frequency sounds, makes it difficult to understand human speech especially in noisy environments

Age related hearing loss
- reduction in the size and quality of social network
- can lead to depression and loneliness
Onset of hearing loss and risk for neurocognitive disease
- evidence that hearing loss in midlife or later is associated with an increased risk for Alzheimer’s or other neurocognitive diseases

Learning theory
- aka behaviorist theory
- languages learned by like other behaviors through imitation and reinforcement
- children acquire language by copying the speech of others and being reinforced to do so

Nativist theory
-chomsky
- children have a innate language acquisition device. (LAD) That allows them to understand language and speak in rule govern ways once they have been sufficiently exposed to language
Nativist theory
-chomsky
- children have a innate language acquisition device. (LAD) That allows them to understand language and speak in rule govern ways once they have been sufficiently exposed to language
Evidence for chomsky’s theory
- research showing that all languages have The same basic underlying structure
Criticism for learning theory and nativist theory
- is that neither accounts for all aspects of language acquisition

- is that neither accounts for all aspects of language acquisition
Social interactionist theory
- combines aspects of learning theory and nativist theory
-many versions, all share The assumption that language depends on both biological and social factors
-bio factor- provide a predisposition/readiness for language acquisition
- social factors: meaningful social interactions, support, language development
Support for social interactionist theory
- research has identified a variety of ways that parents and other adults facilitate a young child’s language development
- child directed speech: motheese and parenties And involves speaking slowly in a high-pitched voice using a limited vocabulary and simple repetitive sentences and focusing on present events
Babbling
- 3 to 6 months
- repetition of consonant- vowel sounds.
-na na na na
- initially include sounds of all languages but by 9 months narrows down to the babies native language

Echolalia
- repetition of of adult speech sounds and words without understanding the meaning
9 mos
First words
- 10 to 15 months
- usually refer to familiar people/pets, movable or manipulative objects or actions
Holophrastic speech
- using the same single word with to communicate different meanings with the meaning depending on the context gesture or intonation to convey an entire idea
- 12 to 15 months
- says Kitty and points to cat and means wants to play with Kat
Telegraphic speech
- 18 to 24 months
- simple two-word sentences, only have essential words usually consist of A noun and a verb/adjective
- Good kitty
Get juice
Overextension
- 3 years old
- applies a word to a wider range of objects than appropriate
- use cat to refer to all furry four-legged animals
Underextension
- applies word to narrowly
- 3 years old
- uses the word cat to only refer to family pet
- evidence that it’s more common
Overegularization
- 3 to 4 years old
- apply rules to words that are exceptions
Ex. Telled, feets

Piaget’s constructivist theory
- cognitive development is an active process that depends on biological, maturation and experience
- child constructs knowledge by interacting with environment
Equilibration
Piaget
- And they drive towards the state of cognitive equilibrium that provides the motivation for cognitive development
Disquilibration
- child experience is a discrepancy between reality and their view or understanding of reality
Restoring equilibrium
Piaget
- restored through adaptation, which consists of two complementary processes assimilation and accommodation
Assimilation
Piaget
- child applies existing cognitive schema to new object or situation
Accommodation
- Piaget
- child modifies existing cognitive schema or creates new schema to fit an object or situation
Piaget stages of cognitive development
- four universal stages that are the same for all kids
- involve qualitatively different ways of thinking
- Sensorimotor stage
- Pre operation stage
- Concrete operational stage
- Formal operational stage
Sensorimotor stage
-piaget
-involves coordinating sensory input with motor actions
Primary accomplishments:
*Development of Object Permanence
*Representational (symbolic) thought
*Make-believe play
*Deferred imitation

Primary accomplishments:
*Development of Object Permanence
*Representational (symbolic) thought
*Make-believe play
*Deferred imitation
Development of Object Permanence
Piaget
-people and objects exist even when they can’t be seen or heard
Representational (symbolic) though
Piaget
-use gestures/words etc to represent objects and experiences
Deferred imitation and make believe play
-able to do these bc of representational thought
Deferred imitation
Piaget
-can observe behavior and repeat it later
Make believe play
Piaget
- also known pretend or symbolic play
- acting out day-to-day activities
Pre-Operational stage
Piaget
2 to 7 years old
- symbolic thought increases and allows for kids to think about the past and things that aren’t in the immediate environment
- also allows for more elaborate forms of make believe play i.e able to use objects to represent another, And take on various roles
- Pre-Operational thought is limited by transductive reasoning and egocentrism
- magical thinking and animism
Transductive reasoning
Aka pre-causal reasoning
- leaves pre-operational kids to believe that two events that occur at the same time are causally related
Limitations of pre-operational stage
Piaget
Transductive reasoning
Egocentrism
- can’t conserve
Egocentrism
Piaget
- The inability to understand that others do not experience things in the way that you do
- manifestations are magical thinking and animism
Magical thinking
Piaget
- The belief that just thinking about something will make it happen
Magical thinking
Piaget
- The belief that just thinking about something will make it happen
Animism
Piaget
- inanimate objects have feelings and lifelike qualities
Conservation
- unable to understand that certain physical characteristics remain the same when objects outward appearance changes
- due to a lack of centration and irreversibility
Conservation
- unable to understand that certain physical characteristics remain the same when objects outward appearance changes
- due to a lack of centration and irreversibility
Centration
Piaget
- tendency to focus on one detail of an object or situation
Irreversibility
Piaget
- inability to understand that an action or process can be reversed
Concrete operational stage
Piaget
7 to 12 years old
- able to use logical operations for mental activities to think logically about concrete situations I cannot directly perceive
- can classify objects, work with numbers, and understand causality
Logical operations of concrete operational stage
- Piaget
+ Decenation
+ Reversibility
Decentration
- piaget
able to focus on more than one aspect of an object or event at the same time
Reversibility
Piaget
- ability to understand that objects and processes can be reversed
Formal operational stage
Piaget
- 12 and up
Individuals in this stage can think abstractly which allows them to engage in hypothetical deductive reasoning and propositional thought
- beginning of stage characterized by renewed in egocentrism
Renewed egocentrism
- inability to separate one’s own abstract thoughts from those of others
Described by Elkind as manifested as the personal fable and imaginary audience
