Developmental Psychology Flashcards
Developmental Psychology
Describes and explain changes in human behavior over time
British Empiricist School of Thought
Believe that all knowledge is gained through experience
Tabula Rasa
Child’s mind at birth is considered a blank slate ; without predetermined tendencies
Functionalist System of Thought
Studies how the mind functions to help the individual adapt to the environment
Psychodynamic Orientation
Stressed the roles of subconscious conflicts in the development of functioning and personality
Cognitive Structuralists
Emphasize the thinking ability of people during development
Cross-Sectional Studies
Compare groups of subjects at different ages
Longitudinal Studies
Compare specific groups of people over an extended period of time
Sequential Cohort Studies
Several groups of different ages are studied over several years
Case Study (Clinical Method)
Look at facts about a particular person and their environment in order to gain a better perspective
Nature / Nurture Controversy
Nature - human capabilities are innate (present at birth) and differences are largely due to genetics
Nurture - human capabilities are determined by the environment and shaped by experience
**Capabilities are actually a result of a dynamic interaction between nature and nurture
Family Studies
Studying one family to determine degree of genetic influence
Monozygotic Twin Studies
Twins are genetically identical (sharing 100% of their genes)
Dizygotic Twin Studies
Twins are genetically similar - share approximately 50% of their genes
Adoption Studies
Compare the similarities between the biological parents and the adopted child to similarities between the adoptive parents and the adopted child
Down’s Syndrome
Genetic anomaly where an individual has an extra 21st chromosome - results in varying levels of mental retardation
Phenylketonuria (PKU)
Degenerative disease of the nervous system - the enzyme needed to digest phenylalanine (found in milk and other foods) is lacking
Klinefelter’s Syndrome
In males - a possession of an extra X chromosome
They have an XXY configuration - they are often steril and have mental retardation
Turner’s Syndrome
Females with only one X chromosome - they fail to develop secondary sex characteristics and have physical abnormalities
Zygote
The sperm cells fertilizes the egg cell and forms a single cell
Germinal Period
Prenatal stage lasting two weeks after time of conception where the fertilized egg travels down the Fallopian tube and is implanted into the uterine wall
Embryonic Period
The 8 weeks following the Germinal Period - embryo increases in size (2 million %); begins to look human and first movements will occur
Fetal Period
Begins in the third month - fetus’ brain has measurable electrical activity & the baby grows in size
Prenatal Development Stages (in order)
- Zygote
- Germinal Period
- Embryonic Period
- Fetal Period
Rooting
Infant reflex where they turn their heads in the direction of the stimuli applied to their cheek
Moro
Infant reflex where they react to abrupt movements of their heads by flinging out their arms, extending their fingers, bringing their arms back to their body and then hugging themselves
Babinski
Infant reflect where toes automatically spread apart when the soles of their feet are stimulated
Grasping
Infant reflex where they automatically close their fingers around objects that are placed in their hands
Schema
Organized patterns of behavior and / or thought
Concept, Behavior or Sequence of events
Principle of Adaptation
- (Jean Piaget)
To process new information
- Assimilation - process of interpreting new information in terms of existing schema
- Accommodation - modify existing schema to adapt to this new information
Stages of Cognitive Development
- (Jean Piaget)
- Sensorimotor (infancy)
- Preoperational (2-7 yrs)
- Concrete Operations (7-11 yrs)
- Formal Operational (11+ yrs)
Sensorimotor Stage
- Primary (motions concerned with body) and Secondary (manipulation objects in the environment) repetitive reactions (circular movements) help to coordinate different aspects of the environment.
- Object Permanence develops - objects still exist even when they are out of view
Preoperational Stage
- Child has not mastered conservation
- Egocentrism - focus on themselves and do not understand perspective of others
- Centration - focus on one part of a phenomena
- Beginning of representational thought
- Symbolic thinking - pretend, make believe and imagine
Concrete Operational Stage
- Conservation - physical properties of matter remain the same even if appearance may change
- Able to take the perspective of others into account
Formal Operations Stage
Person has the ability to think logically about abstract thoughts / ideas
Lev Vygotsky’s Perspective on Children
The engine driving the cognitive development is the child’s internalization of interpersonal and cultural rules and processes (rules, symbols, language, etc…)
Phonology (Phonemes)
Actual sound stem of language; smallest sound unit of language
Categorical Perception
Distinguishing between differences in sound that do not denote differences in meaning and those differences in sound that do denote differences in meaning
Semantics
Learning the meaning of words and sentences
Syntax
How words are put together to form sentences; grammatical arrangement of words
Pragmatics
Consists of the actual efficient use of language, including recognizing inflections and being able to use them
