Chapter 2 - Developmental Psychology Flashcards
Developmental Psychology
Describe and explain changes in human behavior over time
John Locke
Tabula Rasa
Jean-Jacques Rousseau
opposed Tabula Rasa, society was not only unnecessary but also a detriment to optimal development
Charles Darwin
Evolutionary theory stressed the functionalist system of thought, also caused researchers to become interested in the study of individual differences in abilities such as hearing, seeing, and problem-solving
Functionalist System of Thought
The importance of studying the mind as it functioned to help the individual adapt to the environment
G. Stanley Hall
father of developmental psychology
John Watson
criticized a focus on mentalistic concepts, agreed with tabula rasa, believed emotions as well as thought were acquired through learning
Arnold Gesell
developmment occured as a biological process, blueprint from birth, “nativist”
Psychodynamic Orientation
system of thought that arose out of clinical settings, stress the role of subconscious conflicts in the development of functioning and personality, Freud
Cognitive Structuralists
strongly influenced by Piaget, opposition to the behaviorists
Cross-sectional studies
compare groups of subjects at different ages
Longitudinal Studies
compare a specific group of people over an extended period of time
Sequential Cohort Studies
Combine cross-sectional and lognitudinal research methods, int his combined approach, several groups of different ages are studies over several years
Clinical Method/Case STudy Method
Looking at the development of a particular child
Nature/Nurture Controversy
polarity has largely disappeared, development is the result of a dynamic interaction
Gregor Mendal
hypothesized the existence of the gene
R.C. Tryon
Inheritance of maze-running ability in laboratory rats, one of the clearest example of the heredity of behavior (1942)
Twin studies
monozygotic (MZ) and dizygotic (DZ) MZ twins tend to be more similar in regard to cognitive social and emotional characteristics, suggesting some genetic influence
Lewis Terman
compared group of children with high IQs to typical, first study to focus on “gifted” children and a large-scale longitudinal study followed every 5 years
Down’s Syndrome
Extra 21st chromosome, older parents have increased risk
Phenylketonuria (PKU)
genetic disorder, degenerative disease of nervous system. first genetic disease that could be tested in large populations
Klinefelter’s Syndrome
possession of an extra X in males, sterile and often have mental retardation
Turner’s Sydrome
Females with only one X, physical abnormalities
Gamates
Ovum or egg cell and sperm, sex cells
Zygote
Fertilized Egg Cell
Germinal Period
The fertilized egg travels down the fallopian tube and is implanted into uterine wall
Embryonic Period
the 8 weeks following the germinal period; embryo increases in size by 2 million percent
Fetal period
Begins in the third month with measurable electrical activity int he fetus brain
Rooting Reflex
automatic turning of the head in the direction of a stimulus that touches the cheek
Moro Refle
Infants react to abrupt movements of their heads by flinging out their arms, exxxtending their fingers, bringing their arms back to their body and then hugging themselves
Babinski Reflex
Infants’ toes automatically spread apart when the soles of their feet are stimulated
Grasping
Infants automatically close their fingers around objects placed in their hands
Jean Piaget
qualitative differences between adult and child thought, four stages of cognitive development, cognitive growth as a continuous process, believed that development of thought that directs development of language
Schema
Organized patters of behavior and/or thought
Adaptation
adaptation takes place through two complementary processes - assimilation and acocommodation
Assimilation
interpreting new information in terms of existing schemata, (part of Piaget’s adaptation)
Accommodation
when new information doesn’t really fit into existing schemata, (part of Piaget’s adaptation)
Sensorimotor
Piaget’s First Stage of Cognitive Development, primary and secondary circular reactions; object permanence develops
Primary Circular Reaction
goal-oriented behavior during sensorimotor stage, ex.sucking indiscriminately, trying to gain satisfaction from putting something in his or her mouth, repitition ocncerned with the body
Secondary Circular Reaction
during sensorimotor stage, repetition concerned with the environment (0-2 years of age)
