Exam 3 Flashcards
Development Psychology
Study physiological and cognitive changes across the life span and how these are affected by a person’s genetic predispositions,culture,circumstances, and experiences.
Socialization
The process by which children learn the rules and behavior expected of them by society.
Germinal Stage of Development
Begins at fertilization, when the male sperm unites with the female ovum(egg);the fertillized single-celled egg is called a zygote.
Embryonic Stage of Development
Begins about two weeks after fertilization and lasts until the eighth week after conception.
Fetal Stage of Development
Begins after eight weeks,and the organism, now called a fetus,futher develops the organs and systems that exisited in rudimentary form in the embryonic stage.
Rooting
Occurs when a person touches(strokes) the corner of a baby’s mouth and the baby will turn its head and open it’s mouth to follow and “root” in the direction of the touch(stroke).
Sucking
Occurs when the roof of the mouth is touched.
Swallowing
Stimulating the palate causes swallowing
Moro(“startle”)
Happens when a baby is startled by a loud noice or movement and reaches out and cries.
Babinski reflex
Sole of foot is touched and big toe bends back to top of foot and other toes fan out.
Grasping
Stroke a baby’s palm and their hand closes around the finger.
Stepping
Baby appears to be taking a step when their feet touches the ground.
Attachment Theory
Children gain a secure base by attaching to the caregiver. Infants usually find a balance between secure attachment to the caregiver and feeling free to explore the environment.(John Bowlby(1963,1979))
Contact Comfort
Comfort derived from an infant’s physical contact wiht the mother or caregiver.
Strange Situation Test
- Mother brings the baby in an unfamilliar room with toys.
- After awhile a stranger comes in and tries to play with the baby.
- The mother leaves the baby with the stranger.
- Mother returns, plays with the child, and the stranger leaves.
- Mother leaves the baby for three minutes, and returns.
Secure Attachment
A parent-infant relationship in which the baby is secure when the parent is present, distressed by separation and delighted by reunion.
Insecure Attachment
Two types: Avoidant and Anxious-ambivalent. A parent-infant relationship in which the baby clings to the parent,cries at separation, and reacts with anger or apathy to reunion.
Language Development
Acquisition of speech begins in the first few months. Infants are responsive to pitch,intensity, and sound. By 4-6 months of age children can recognize their names and repetive words. By 6-12 months of age children become familliar with sentence structure and start babbling. By 11 months infants use symbolic gestures. At about 12 months infants use words to label objects. Between 18-24 months, toddlers combine 2-3 words into telegraphic speech.
Assimilation
Absorbing new information into existing cognitive structures.
Accommodation
Modifying existing cognitive structures in response to new information.
Sensorimotor Stage
Birth to 2 years. Major accomplishment is object permanence. between 4 and 9 months. Knowledge through senses(tasting, seeing, smelling, touching, hearing).
Preoperational Stage
2-5 years. Verbal and egocentric thinking develop. Can do mentally what once could only do physically. Conservation of shape, number, liquid are not yet possible.
Concrete Operational
6-11 years. Conservation of shape, number, liquid are now possible. Logic and reasoning develop, but are limited to appearance and what is concreatly observed.
Formal Operational
12 and up. Abstract reasoning-principles and ideals develop. Systematic problem solving is now possible(no longer just trial and error). Ability to think about and reflect upon one’s thinking (metacognition). Scientific Reasoning
Lev Vygotsky
Felt cognitive development was more of a social process. Children develop mental representations of the world through culture and language, and that adults play a major role in their children’s development by constantly guiding and teaching them. Zone of proximal development-the distance between what a child can learn alone and what the child can learn assisted by an adult.
Kolhberg’s Theory of Moral Development
Level 1: Preconventional level-Stage 1: Punishment and obedience. Stage 2- Instrumental relativism. Level 2: Conventional- Stage 3: Good boy-Nice girl. Stage 4-Society maintaining(law and order) Level 3: Postconventional-Stage 5: Social Contract Stage 6: Universal ethical principles.
Power Assertion
Parent uses punishment and authority to correct misbehavior.
Induction
Parent appeals to child’s own resources, abilities, sense of responsibility, and feelings for others in correcting misbehavior.
Self-Regulation
The ability to suppress an initial wish to do something in favor of doing something else that is not as much fun.
Gender Identity
The fundamental sense of being male or female, independent of whether the person conforms to social and cultural rules of gender.
Intersex Conditions
Chromosomal or hormonal anomalies cause the child to be born with ambiguous genitals or genitals that conflict with the infant’s chromosomes.
Adolescence
A transition period between childhood and adulthood that brings challenges and excitement.
Puberty
The age which a person becomes capable of sexual reproduction
Influences of Timing of Puberty
Onset of puberty depends on genetic and environmental factors:Body fat triggers the hormonal changes. Early vs Late Onset: Early maturing boys have more positive views of their bodies and are more likely to smoke, binge drink, and break the law. Early maturing girls are usually socially popular but also regarded by peer group as precocious and sexually active. They are more likely to fight with parents, drop out of school, and have a negative body image.
Erikson’s Eight Stages
Trust versus Mistrust: Infancy(birth-age 1), Autonomy versus shame &doubt:Toddler(ages 1-2)
Initiative vs Guilt: Preschool(ages 3-5)
Competence vs Inferiority: Elementary School(ages 6-12)
Identity vs. Role Confusion: Adolescence(ages 13-19)
Intimacy vs. Isolation: Young Adults(20-40)
Generativity vs. Stagnation Middle age(40-65)
Ego Integrity vs. Despair Old age(65-older)
Adult Development
Psychological concerns can occur at any time in life, therefore stage theories are no longer used to understand how adults change or stay the same. Adult development involves interactions among: Biological changes, Personality traits, Personal experiences, Historical Events, Particular Environments and Friends and Relationships.
Emerging Adulthood
(18-25) A transitional time between adolescence and young adulthood. Increase responsibilities and demands. 3 important issues: Career Identity, Sexual Identity and Ethnic Identity.
Young Aduthood
(Mid 20s) Begins when key tasks of emerging adulthood have been completed. Differs across culture. Several “events” may occur during this time: marriage- age of marriage has increased over the last 50 years; Parenthood.
Middle Years
(35-65) Percieved by many as the prime of life. sensory and brain development: loss of some hearing and visual abilities is normal neurgenesis tapers off. Menopause- the cessation of mestruation and the production of ova, usually a gradual process lasting several years.
Old Age
(65 and up) Brain mass decreses, and frontal lobe changes account for many of the cognitive changes of the later years. Some types of thinking change, others stay the same. Apparent senility often caused by combinations of medications. Depression and passivity are result of loss of meaningful activity, intellectual stimulation, and control over events. Weakness and frailty caused by sedentary lifestyles. Gerontologists estimate that only 30% of the physical losses associated with old age are genetically based. The rest are environmental or psychological.
Fluid Intellegence
The capacity for deductive reasoning and the ability to use new information to solve problems; relatively independent of education, declines in old age.
Crystallized Intellegence
Cognitive skills and specific knowledge of information acquired over a lifetime; depends heavily on education, remains stable over lifetime.
Lifespan Intellectual Changes
Some intellectual abilities dwindle with age. Numerical and verbal abilities relatively stable.
Socioemotional Selectivity Theory
Challenges the association of old age with declines. Time perspective changes the importance of emotional goals. Older adults have emotionally closer and tighter social networks. Older adults are happier compared to younger adults. Older adults have better memory for positive and emotionally meaningful information. ( Laura Carstensen, 1992)
Concept
A mental category for elements of our environment(or imagination) that share properties.
Prototype
The best example of the average/central tendency of a category.
