Psychology Human Development
is the scientific study of the changes that occur in people as they age from conception until death
in which one group of people is followed and asserted a different times as the group ages
Cross Sectional Design
Several different age groups are studied at one time (very quick)
Cross Sequential Design
which a combination of the two other designs (Longitudinal Cross-Sectional)
The particular impact on development that occurs when a group of people share a common time period or common life experience (Example, being born in the same time period)
Heredity/ the influence of inherited characteristics on personality, physical growth, intellectual growth, and social interactions
The influence of the environment on all of those same things including physical surroundings, and economic factors.
Is a field in the investigation of the origins of behavior in which researchers try to determine how much of behavior is the result of genetic inheritance and how much is due to a person experience
The science oh Heredity
DNA (deoxyrobonucli acid)
special molecule contains twp very long sugar-phosphate strands linked together b bases or amines arranged in a particular pattern. Contains genetic codes (makeup, color, muscle, and skin)
Each section of DNA contains a certain sequence ordering of these amines
Rod shaped structures that hold genes and are located in the nucleus of the cell.
Most characteristics are determined by how many chromosomes?
Genes that are more active in influencing the trait
Less active in influencing the trait. These genes tend too recede, fade into the background when paired with the dominant gene.
Certain genes tend to group themselves together. Ex) Blonde hair and blue eyes and Strawberry Blonde
Inherited recessive gene disease. Respiratory digestive tracts
Sickle Cell Anemia
Inherited recessive gene disease, blood disorder
Neurological disorder, Inherited recessive gene disorder
A birth defect that causes an amino acid called phenylalanine to build up in the body. Inherited recessive disorder
Chromosome Disorder, Extra chromosome
Chromosome Disorder, 23rd sex chromosome
Lone X chromosome, Chromsome disorder
What are eggs called in the prenatal phase?
When the egg and sperm unit
the resulting single cell with the 46 chromosomes, begins to divide
the division process because DNA molecules produce duplicates or copies of themselves before each division
Identical twins babies come from one fertilized egg
Also known as fraternal twins, when two eggs are fertilized or could possible have triplets
when the mass of cells does not completely split apart

Most babies are born between when?
Babies born before 38 weeks
the longer the infant spends looking at a stimulus, the more the infant, prefers the stimulus than others.
is the tendency for infants (and adults) to stop paying attention to stimulus that does not change
as unused synaptic connections and nerve cells are cleared away to make way for functioning connections and cells
What are the last sensory organ to develop?
development of thinking, problem solving, and memory
What are the four stages of Piagets Theory?
1. The Sensorimotor Stage, 2. The Preoperational Stage, 3. Concrete Operations 4. Formal Operations
What are Schemes?
try to understand new things in terms of schemes they already possess
process of altering or adjusting old schemes to fit new information and experiences
The Sensorimotor stage
Stage (birth-2 years old) infants use their sensory and motor skills to understand the world around them. Ex) grasping, touching, pushing, tasting, etc.
fully developed at the end of this stage, the knowledge that an object exists even when it is not in sight. Ex) Peek a boo
The Pre-operational Stage
Ages 2-7. When children develop language and concepts. Are able to ask questions. Symbolic meaning, make-believe play, not capable of logical thought.
they believe that everything that moves is alive
the ability to see the world through anyone else’s eyes but ones own
Focusing only on one feature of some object rather than taking in all factures into consideration
Unable to mentally reverse actions, unable to concentrate
finally become capable of conversation and reversable thinking, begin to think more logically. Can deal with abstract objects.
Kind of concepts which are understood at the concrete operation phase
Ages 12- adulthood, abstract thinking becomes possible, gets deeply involved in hypothetical thinking
the more highly skilled person gives the learner more help at the beginning of the learning process and then begins to withdraw help as the learner is skills improve
Zone of Proximal Development
difference between what a child can do alone versus what a child can do with the help of a teacher
Receptive Productive Lag
a phenomenon that infants may only seem to produce one or two words but they can understand actual sentences
What are the five stages to language?
Cooing, babbling, one word speech, telegraphic speech, whole scentences
2 month vowel sounds
6 months, add constants
One word speech
around age 1, say actual words, typically nouns
1.5 years, begin to say short simple sentences, nouns, verbs, and adjectives
Pre-school years, learn grammical terms
Autism Spectrum Disorder
Neurodevelopment disorder that encompasses a whole range of previous disorders
the behavioral and emotional characteristics that are fairly well established at birth
regular in schedules in waking, sleeping, and eating “happy babies”
irregular in their schedules and very unhappy about change, “loud, active, and crabby”
Slow to Warm up Babies
less grumpy, quieter, and more regular than difficult children, but slow to adapt to change
Emotional bond that forms between an infant and the primary caregiver
wariness of strangers
fear of being separated from caregiver
What are the attachment styles?
Secure, Avoident, Ambivalent, Disorganized-Disoreinted
Secure Attachment Style

physical changes in the body primarily ses characteristics and secondary characteristics
adolescents have spent so much time thinking about their own thoughts and feelings that they become convinced that they are special.
shows up as extreme self consciousness in adolescents they are convinced that “everyone is looking at them”
Very young children, based on consequences
Older children, adolescents, most adults, actions are morally right if it conforms to the rules to society
1/5 of the population, made by experiences and judgement of the individual.
the cessation of ovulation and the menstrual cycle
decline of several hormones in males (testosterone)
very few demands on their children for behavior
tends to be overly concerned with rules. Very stern and rigid and controlling. Physical punishment
parents aren’t involved with their children, letting them do whatever they want
parents seem to be too involved with their children allowing their “little angels” to behave however they want. Children tend to be selfish, immature, dependent, lacking in social skills.
involves combining firm limits on behavior with love, warmth, affection, respect and willingness to listen to the child’s point of view, non-physical punishment
wholeness results they look back and feel that their lives were full
Cellular Clock Theory
Cells are limited in the numbers of times they can reproduce to repair damage, the evidence is the existence of telomeres.
Wear and Tear Theory
the one that points to outside influences (stress, physical exertion, and bodily damage) The body’s organs and cell tissues simply wear out with repeated use
Free Radical Theory
free radicals are oxygen molecules that have an unstable election, as people get older, more and more free radicals do more and more damage
Proposes that an elderly person adjusts more positively to aging when remaining active in some way
