Developmental Psych Flashcards
Watson, John
Environmental influences important on child development, locke’s tabula rasa
Emotions and thought acquired through learning
Place a responsibility on parents for raising
DISCREDITED consciousness, will, mental states
Predict behavioral responses given a stimuli
lil Albert
Conditioning learning practice
Gesell, A
Development is a maturational/biological process
Nativist=believed much of development was biologically based
Developmental blueprint exists from birth
Against behaviorism
Psychodynamic orientation
subconscious conflicts in the development of functioning and personality
S Freud
Cognitive theories
Thinking ability of people, children constructing knowledge of the world through their experiences with environment
J Piaget
Research methods dev HOW
Longitudinal specific group over time
Cross-sectional compare groups at dif ages
Sequential cohort several groups of dif ages looked at over time
Clinical/Case study: one persons past present and future
Nature v nurture
Nature: human capabilities are innate, and a person is largely their genetic makeup of predisposition
Nurture: human capabilities determined by environment and shaped by experience
Now–> both
Mendel, G and heredity
Gene: Basic unit of heredity
Allele: alternative form of gene
Dominant or recessive alleles
2 doms or 1 Dom = dominant allele expresses
2 recessive = recessive allele expressed
Parental genes are distributed randomly to all offspring
Genotype | Phenotype BRBR Brown eyes BRbl. Brown eyes blBR. Brown eyes blbl. Blue eyes
Genotype: total genetic complement or makeup
Phenotype: total collection of expressed traits
Genes located on chromosomes, 23rd pair of chrome determines sex
Gametes (sperm and egg cells) are haploid, nucleus has 23 different chromosomes total; when combine they are diploid as cells of the human body and form 23 pairs.
Tryon, R. C.
1942, Studied inheritance of maze running ability in laboratory rats
Maze-bright, maze-dull, and intermediate
Maze brights were only bred with maze brights and same for breeding of maze dulls and the difference intensified over generations
Research methods dev WHO
Family studies, compare rates of similarity between genetically related ppl to genetically unrelated people; I.e. Children of schizophrenics are 13% more likely to develop than general pop
BUT Familys tend to share both genetics and environment
twin studies, MZ and DZ twins share environments to some extent and only the 50% dif in genes sets them apart;
Comparing twins raised apart
MZ twins reared apart are more similar than DZ twins reared together on personality
adoption studies, environmental and genetic influences on behavior; adoptive child’s IQ is that of biological parent, not adoptive
Terman, L
Compared children with high IQ (+135) with average children to discover dif; first to focus on gifted children; large scale longitudinal study
Genetic disorders
Down’s Syndrome: extra 21st chromosome causes severe mental retardation
Phenylketonuria (PKU): genetic defect in which child lacks enzyme needed to digest phenylalanine; controlled with a strict diet; degenerative disease of nervous system
Klinefelter’s Syndrome: extra X chromosome, XXY, sterile and have mental retardation
Turner’s Syndrome: only one X chromosome; C, failure to develop secondary sex characteristics, short fingers and unusually shaped mouths
Prenatal development
Ovum: egg cell, gamete
Sperm cell, gamete
Zygote: combined fertilized egg
Zygote splits in half, and again and again and the cellular mass travels down Fallopian tube and implants on uterine wall
Germinal period: 0-2 weeks
Embryonic stage: 3-8 weeks, develops a human-like appearance, limbs appear and tail recedes, fingers toes and genitalia and nervous system in spine 2 million percent size increase
Fetal period: 3 months, marks measurable electrical activity in brain
Maternal malnutrition =leading cause of abnormal development
Protein deficiency, maternal narcotic addiction, cigarette smoking, daily alcohol consumption, and X-ray
Neonatal reflexes
Moro: stretching out and hugging when head is jerked
Babinski toes spread when feet stimulated
Rooting: turning head towards stimulated cheek for feeding
Grasping: closing fingers around something in hand
Piaget, J
Thoughts
Schema: organized patterns of behavior and/or thought; learn or develop schemata from interacting with environment through reflexive behaviors (learn to grasp from grasping)
Adaptation:
Assimilation- interpreting new information in terms of existing schemata
Accommodation- new info doesn’t match existing schemata, modify existing schemata to adapt new info
Piaget, J
Stages of Cognitive Development
Sensorimotor: 0-2, primary and secondary circular reactions, object permanence
Preoperational: 2-7, beginnings of representational thought with object permanence, centration (focus on only aspect of a phenomenon), egocentrism (does your sister have a sister) also don’t understand conservation
Concrete Operational: 7-11, conserve and overcome centration, only work with concrete objects or info, no abstract thought
Formal Operational: 11+, can do abstract thinking
Development of thought directed development of language
