Midterm Flashcards
(1) (p. 3-5-chp. 1) Know the goals of the science of human development and what we try to understand
The science of human development seeks to understand how and why people of all ages and circumstances change or remain the same over time. The Goal for science is to help all 7 billion people on earth to fulfill their potential
(2) (p. 11-12-chp.1) Know the definition of SES (Socioeconomic Status) and what the components are as well as how it plays a role in human development
SES (Socioeconomic Status) A person’s position in society as determined by income, wealth, occupation, education, and place of residence.
(3) (p.7-12-chp.1) Understand the life span perspective and what time frames are involved
An approach to the study of human development that takes into account all phases of life, not just childhood or adulthood. Leads to new understandings of human development as multidirectional multicontextual multicultural multidisciplinary and plastic Infancy 0-2 Early childhood 2-6 Middle age 6-11 Adolescence 11-18 Emerging adulthood 18-25 Adulthood 25-65 Late adulthood 65 older
(4) (p.5-7-chp.1) Understand the concept of nature and nurture and how they both impact human development
Nature:Influence of genes we inherit
Nurture:Environmental influences that affect development
Environmental influences include such things as: health and diet of the embryo's mother family school community society
(5) (p.6-7-chp.1) Know what SIDS (Sudden Infant Death Syndrome) entails including contributing and preventing factors
SIDS: The term used to describe an infant’s unexpected death; when a seemingly healthy baby, usually between 2 and 6 months old, suddenly stops breathing and dies unexpectedly while asleep.
(6) (p. 23-25-chp. 1) Understand Freud?s Psychoanalytic theory and how it impacts human development. Also, be familiar with his stages of development.
Psychoanalytic theory
Theory Proposes that irrational, unconscious drives and motives, often originating in childhood, underlie human behavior
Freud (1856–1939)
First psychoanalyst
Proposes five psychosexual stages during which sensual satisfaction is linked to developmental needs and conflicts.
Suggests early conflict resolution determines personality patterns
1. Oral stage mouth sucking
2. Anal stage anus toilet training
3. Phallic stage boys proud of penis, girls wonder why they don’t have one
4. Latency stage sexual needs are quite energy towards sports school
5. Genital stage sexual stimulation
(7) (p. 26-28-chp.1) Be familiar with the development theory of Behaviorism and know the what is involved as well as the key concepts of conditioning, reinforcement, punishment, and social learning
John B Waston created the Behaviorism a theory of human development that studies observable behavior, also called learning theory. it describes the law and processes by which behavior is learned.
conditioning: responses become linked to particular stimuli and learning takes place.
Classical conditioning stimulus sound of bell
Operant conditioning if response is pleasurable action will take place repeated
reinforcement: behavior is followed by something desired
punishment:
social learning: the acquisitions of behavior patterns by observing the behavior of others
(8) (p.29-31-chp.1) Know Piagets theory of cognitive development including the various stages
Cognitive theory Proposes thoughts and expectations profoundly affect actions, attitudes, beliefs and assumption Focuses on changes in how people think over time
Jean Piaget (1896–1980)
Maintained that cognitive development occurs in four major age-related periods, or stages:
Sensorimotor, infant use senses and motor abilities
preoperational, children think magically and poetically using language.
concrete operational, children understand and apply logic
formal operational: adolescents and adults think abstractions and hypothetical concepts and reason
with all this stages Intellectual advancement occurs lifelong because humans seek cognitive equilibrium
(9) (p. 29-31-chp.1) Know Vygotskys theory of cognitive development and what his theory entails and how it may differ from the other cognitive theories
Vygotskys theory of cognitive development emphasizing the cultural context
Described interaction between culture and education
Proposed guided participation is a universal process used by mentors to teach cultural knowledge, skills, and habits
(10) (p. 47-52-chp.2) Understand the role that genes and chromosomes play in prenatal development including the very beginning components of conception
Genes are the foundation for all development. human conception occurs when two gametes (ovum and sperm, each with 23 chromosomes) combine to form zygote, 46 chromosomes in a single cell.
(11) (p. 57-61-chp.2) Know the different stages of prenatal development and what they entail
Three main periods of prenatal development Germinal Period (first two weeks after conception): rapid cell division and beginning of cell differentiation Embryonic Period (3rd through 8th week): basic forms of all body structures develop Fetal Period (9th week until birth): fetus grows in size and matures in functioning
(12) (p. 60-61-chp.2) Understand the age of viability
Age of viability
Age at which a preterm newborn may survive outside the mother’s uterus if medical care is available
About 22 weeks after conception
Brain is able to regulate basic body functions (e.g., breathing)
Chances of survival increase with each day after the 22-week mark.
Viability This fetus is in mid-pregnancy, a few weeks shy of viability. As you can see, the body is completely formed. Unseen is the extent of brain and lung
Even with advanced medical care, survival of extremely preterm newborns is in doubt. These data come from a thousand births in Sweden, where prenatal care is free and easily obtained. As you can see, the age of viability (22 weeks) means only that an infant might survive, not that it will. By full term (not shown), the survival rate is almost 100 percent.
development, which will take at least another month to become sufficiently mature to allow for survival
(13) (p. 72-74-chp.2) Know the critical period of highest vulnerability in prenatal development in which teratogens affect the developing baby (including figure 2-9, p. 74 the period that has the most green bars=highly critical period)
Critical period
Time when a body part develops
First two months for structural abnormalities
Often before woman knows she is pregnant
Time when most spontaneous abortions occur
Some teratogens cause damage only during a critical period.
First days and weeks after conception (the germinal and embryonic periods) are critical for body formation.
Entire fetal period is a sensitive time for brain development.
Timing between pregnancy affects risk.
Furthermore, preterm birth is a risk factor that is affected by nutrition and drugs throughout pregnancy.
The most serious damage from teratogens (green bars) is likely to occur early in prenatal development. However, last months of pregnancy as well. Behavioral teratogens also affect the fetus throughout development.
(14) (p. 93-96-chp.3) Know what a neuron is and what it entails including its parts and the role each neuron plays in the nervous system
Neuron: One of billions of nerve cells in the central nervous system (CNS).
Axon: Fiber that extends from a neuron and transmits electrochemical impulses from that neuron to the dendrites of other neurons.
Dendrite:Fiber that extends from a neuron and receives electrochemical impulses transmitted from other neurons via their axons.
Synapses:Intersection between the axon of one neuron and the dendrites of other neurons.
Neurotransmitter:Brain chemical that carries information from the axon of a sending neuron to the dendrites of a receiving neuron.
(15) (p. 100-103-chp.3) Be familiar with how babies develop their ability to sense and perceive & know the difference between sensation & perception
Sensory development
Typically precedes intellectual and motor development
Sensation
Response of a sensory system (eyes, ears, skin, tongue, nose) when it detects a stimulus
Perception
Mental processing of sensory information when the brain interprets a sensation, happenes in cortex
Perception follows sensation.
Infants’ brains are especially attuned to their own repeated social experiences and perception occurs.
Infant brain and auditory capacity to hear sounds in the usual speech range.
The parts of the cortex dedicated to the senses develop rapidly.
Sense of hearing
Develops during the last trimester of pregnancy
Most advanced of the newborn’s senses
Speech perception by 4 months after birth
(16) (p.109-113-chp.3) Be familiar with the pros and cons of breast versus bottle feeding and how each can impact nutrition and development
Adequate nutrition
For every infant disease (including SIDS), breast-feeding reduces risk and malnutrition increases it, stunting growth of body and brain.
Breastfed babies are less likely to develop allergies, asthma, obesity, and heart disease.
As the infant gets older, the composition of breast milk adjusts to the baby’s changing nutritional needs.
compared with formula based on cows milk human milk is sterile at body temperature, rich in iron, vitamins, other nutrients for the brain and body.
breast fed are less often sick, provides antibodies, less likely to become obese, thus less likely to develop diabetes or heart disease
(17) (p. 114-117-chp. 3) Review Piagets cognitive stage of development in the first two years, the Sensorimotor Stage, and know what it entails in terms of cognitive development
Sensorimotor intelligence
Piaget’s term for the way infants think—by using their senses and motor skills—during the first period of cognitive development.
the first two stage involves the infants response to its own body. second stage involves the infant responses to objects and people the last two are the mos creative with actions then ideas.
(18) (p.120-127-chp.3) Understand how children develop language and what this important developmental milestone entails including key concepts, details and how we talk to children as they learn language
Infants teach themselves.
Language learning is innate; adults need not teach it, nor is it a by-product of social interaction
Child-directed speech
High-pitched, simplified, and repetitive way adults speak to infants
Babbling
Extended repetition of certain syllables, such as ba-ba-ba, that begins when babies are between 6 and 9 months old
Naming explosion
Sudden increase in infant’s vocabulary, especially in the number of nouns, that begins at about 18 months of age
High-pitched, simplified, and repetitive way adults speak to infants (Also called baby talk or motherese).
(19) (p.132-135-chp. 4). Solidify your knowledge of emotional development in the first few years of life including what and how emotions develop
Smiling and laughing
Social smile (6 weeks): Evoked by viewing human faces
Laughter (3 to 4 months): Often associated with curiosity
Anger
First expressions at around 6 month
Healthy response to frustration
Sadness
Indicates withdrawal and is accompanied by increased production of cortisol
Stressful experience for infants
(20) (p.137-139-chp. 4) Understand the concept of temperament and be familiar with the research and various types or categories)
Temperament
Inborn differences between one person and another in emotions, activity, and self-regulation
Temperament is epigenetic, originating in the genes but affected by child-rearing practices
Categories
Easy (40%)
Difficult (10%)
Slow to warm up (15%)
Hard to classify (35%)
NYLS additional findings
Temperament often changes in the early weeks but is increasingly stable by age 3.
Extreme temperaments at age 3 tend to carry over to adolescence and young adulthood.
Parenting practices are crucial, temperament can change or be changed.
Longitudinal study of infant temperament (Fox et al., 2001)
Grouped 4-month-olds into three distinct types based on responses to fearful stimulation
Positive (exuberant)
Negative
Inhibited (fearful)
Less than half altered their responses as they grew older
Fearful infants were most likely to change
Exuberant infants were least likely to change
Maturation and child rearing has effect on inborn temperament
(21) (p. 142-147-chp.4) Know all about attachment as an important milestone is human development and what it entails
Attachment
Lasting emotional bond that one person has with another
Begin to form in early infancy and influence a person’s close relationships throughout life
Secure attachment
An infant obtains both comfort and confidence from the presence of his or her caregiver.
Insecure-avoidant attachment
An infant avoids connection with the caregiver, as when the infant seems not to care about the caregiver’s presence, departure, or return.
Insecure-resistant/ambivalent attachment
An infant’s anxiety and uncertainty are evident, as when the infant becomes very upset at separation from the caregiver and both resists and seeks contact on reunion.
Disorganized attachment
A type of attachment that is marked by an infant’s inconsistent reactions to the caregiver’s departure and return.
(22) (p.142-147-chp.4) Understand the concept of attachment and related research in this area including the secure and insecure attachments and their features
Attachment is measured by the baby’s reaction to the caregivers presence departure and reaction to the caregivers presence, departure and return in the strange situation is crucial. some infants seem indifferent (type A attachment insecure avoidant) or overly dependent type C insecure resistant/ambivalent) instead of secure type B, Disorganized attachment (type D) is the most worrisome. Secure attachment provides encouragement for infants exploration. Some children never form an attachment at all, even an insecure one.Attachment is an affectional tie that an infant forms with a caregiver. Infants shows their attachment through proximity seeking such as approaching and following their caregiver and contact maintaining such as touching snuggling.
secure attachment is a relationship in which an infant obtains both comfort and confidence from the presence of his or her caregiver
(23) (p. 147-148-chp.4) Know the concept of social referencing and how it plays a role in development
As toddlers play they engage in social referencing looking at other peoples facial expressions and body language to detect what is safe, frightening or fun.
Social referencing
Seeking emotional responses or information from other people
Observing someone else’s expressions and reactions and using the other person as a social reference
Utilizing referencing in constant and selective ways
(24) (p.148-149-chp.4) Understand how fathers play a key role in development and how they may compare to mothers, in general
Infants frequently use fathers as partners in synchorony, attachment figures and social references developing emotions and exploring their world via father care giving.
Parental social referencing
Mothers use a variety of expressions, vocalizations, and gestures to convey social information to their infants.
Synchrony, attachment, and social referencing are all apparent with fathers, sometimes even more than with mothers.
