Unit 8 Elaina & Unit 9 & 10 Rachel- Test 3 Flashcards
Define Developmental Psychology:
how we grow, develop, and change throughout the lifespan.
Describe Chromosome:
Rod-shaped structures, found in the nuclei of body cells, that contain all the genes and carry all the hereditary information.
- 23 pairs
- 22 pairs are called autosomes
- 23rd pair is called sex chromosomes
Define DNA:
Genes are segments of this located on each of the chromosomes
Define gene:
Within the chromosomes, the segments of DNA that are the basic units for the transmission of hereditary traits
Describe dominant trait:
A gene that is expressed in the individual
Describe recessive trait:
A gene that will not be expressed if paired with a dominant gene, but will be expressed if paired with another recessive gene
Describe sex chromosome:
- It carries the genes that determine one’s sex and primary and secondary sex characteristics
- Sperm cells and the mature egg cells each have 23 single chromosomes.
- At conception, the sperm adds its 23 single chromosome to the 23 of the egg. This union forms a single cell called a zygote , which has the full 46 chromosomes (23 pairs), which in turn contains about 30,000 genes-the genetic material needed to make a human being.
What are the three stages of prenatal development?
- Period of the zygote
- Period of the embryo
- Period of the fetus
Describe Stage 1- Period of the zygote
Time after Conception: 1 to 2 weeks
Major Activities of the Stage: zygote attaches to the uterine lining; at 2 weeks, zygote is the size of the period at the end of this sentence.
Describe Stage 2- Period of the embryo
Time after Conception: 3 to 8 weeks
Major Activities of the Stage: Major systems, organs, and structures of the body develop; Period ends when first bone cells appear. At 8 weeks, embryo is about 2.5 cm long and weighs about 4g.
Describe Stage 3- Period of the fetus
Time after Conception: 9 weeks to birth (38 weeks)
Major Activities of the Stage: Rapid growth and further development of the body structures, organs, and systems.
What are the environmental influences on an unborn child?
TERATOGENS: Harmful agents in the prenatal environment that can have a negative impact on prenatal development and even cause birth defects.
CRITICAL PERIOD: A period that is so important to development that a harmful environmental influence can keep a bodily structure or behaviour from developing normally.
What are the four adaptive reflexes of a neonate?
- sucking
- swallowing
- coughing
- blinking
What are the physical changes that occur during infancy?
sitting, standing, and walking; physical and motor development proceeds from the head downward to the trunk and legs, so babies lift their heads before they sit, and sit before they walk, etc.
What are the physical changes that occur during puberty?
ejaculation, menarche. Adolescence begins with the onset of puberty–biological changes characterized by a period of rapid physical growth and change that culminates in sexual maturity.
What are the physical changes that occur during middle age?
Menopause–cessation of menstruation; men experience a gradual decline in their testosterone levels.
Piaget’s stages of cognitive development- What is the concept of assimilation and accommodation?
ASSIMILATION: The process by which new objects, events, experiences, or pieces of information are incorporated into existing schemas
ACCOMMODATION: The process by which existing schemas are modified and new schemas are created to incorporate new objects, events, experiences, or information
Define socialization:
- The process of learning socially acceptable behaviours, attitudes, and values
- Every one of us is born into a society
- To function effectively and comfortably within that society, we must come to know the patterns of behaviour that it considers desirable and appropriate.
What are the 8 psychosocial stages of development proposed by Erikson?
- Trust vs. mistrust
- Autonomy vs. shame and doubt
- Initiative vs. guilt
- Industry vs. inferiority
- Identity vs. role confusion
- Intimacy vs. isolation
- Generativity vs. stagnation
- Ego integrity vs. despair
What is the concept of separation anxiety?
- fear and distress when the parent leaves them with another caretaker
- infants show separation anxiety once the attachment has formed
What are the 4 types of attachment identified by Mary Ainsworth?
- secure
- resistant
- avoidant
- disorganized/disoriented
What are the 3 parenting styles outlined by Diane Baumrind?
- Authoritarian Parents - expect unquestioned obedience
- Authoritative Parents - set high standards, give rationale for rules.
- Permissive Parents - set few rules or limits
What are the 3 levels (6 stages) of moral development?
- Conventional - to gain approval or to follow the law.
- Postconventional - to ensure that human rights are protected.
- Preconventional - to avoid punishment or gain a reward.
Why is middle age often considered the prime of life?
Life satisfaction in older adults appears to be most strongly related to good health, as well as to a feeling of control over one’s life.
