WHAT IS DEVELOPMENT?
Define Development (Objective 1)
1. The study of physical and mental growth and behavioral changes in individuals from conception to death is called developmental psychology. This approach is also referred to as life-span development.
Describe the Changes that Occur During Prenatal Development (Objective 2)
2. Development begins at conception, when a sperm fertilizes an egg cell to produce a fertilized egg cell, or zygote .
3. The growth of an individual from conception until birth is called prenatal development.
4. The zygote stage of prenatal development lasts for about 2 weeks, during which time the zygote travels down the fallopian tube to become attached to the wall of the uterus.
5. The embryonic stage of prenatal development lasts from the time the zygote becomes attached to the uterus to about 8 weeks after conception. During this stage, three distinct layers of cells form: the ectoderm, the mesoderm, and the endoderm.
6. During the seventh week of gestation, sexual differentiation occurs. If XY chromosomes are present, male hormones are produced.
7. The fetal stage of prenatal development lasts from the eighth week until birth. During this stage, the various structures grow and become refined.
8. At approximately 9 months after conception, birth occurs and the fetus becomes a newborn baby or neonate .
Outline the Sensory Capabilities of the Newborn Infant (Objective 3)
9. The first two years of life is defined as infancy .
10. Right after birth, the ear canals are filled with amniotic fluid but within a few days, hearing is normal.
11. A classic study by Fantz (1961) demonstrated that infants showed a strong preference for complex visual stimuli, especially if they resembled the human face .
Identify the Variables that Influence the Development of Motor Behavior During Infancy (Objective 4)
12. A reflex is an automatic response to a stimulus that does not necessarily involve direct higher brain functioning.
13. When a baby's cheek is touched and she turns her head toward the source, the baby is demonstrating the rooting reflex.
14. The startle reflex, or Moro reflex, occurs when something in the environment changes quickly. The baby immediately extends both arms and brings his feet close to his body.
15. The Babinski reflex occurs when the bottom of the baby's foot is stroked. The baby first spreads out the toes and then curls them in. Since it is known when these reflexes normally disappear, they can be used to test for neurological development in babies.
16. The fact that children cannot learn until they are mature enough to be able to use their muscles properly is called readiness to learn . A child cannot learn a behavior, such as toilet training, until he is mature enough, physically and mentally.*
Outline Personality Development During Infancy (Objective 5)
17. The tendency to respond to the environment in particular ways is called temperament . Some tendencies include activity level, rhythmicity, distractibility, approach, adaptability, intensity, attention, and quality of mood.
18. Birth order research suggests that first born children tend to be competitive, have higher self- esteem than later borns, and be high achievers.*
19. Among the personality differences that appear very early in life are characteristics associated with sex roles , or labels of masculinity and femininity. Parents treat boys and girls differently, even as babies, and also serve as role models for their children's behavior.
Describe the Sequence of Attachment and Explain How Attachment Develops (Objective 6)
20. The process in which the individual shows behaviors that promote proximity or contact with a specific person is called attachment .
21. Schaffer and Emerson (1964) identified four phases in attachment development. When first born, the neonate is in what might be called the asocial phase, in which people are not distinguished from objects.
22. Within a few weeks after birth, the baby begins to prefer humans to things in the indiscriminant attachment phase.
23. The stage of attachment beginning at about 6 months, in which babies become attached to one special person is called the specific attachment phase.
24. The last stage of attachment in which babies begin to form attachments to other people is called the multiple attachment phase. The process of forming attachments continues throughout life.
25. Ainsworth's measure of attachment in which the infant is placed in an unfamiliar room and increasingly stressed by an unfamiliar person is called the strange situation procedure.
26. In the strange situation procedure, infants who avoid their mothers when reunited with them show avoidant attachment.
27. In the strange situation procedure, infants who actively seek contact with their mothers when reunited with them show secure attachment.
28. Harry Harlow (1958), in his "surrogate mother" experiments, found that contact comfort is important in attachment formation in baby monkeys.
29. One theory of attachment (Scott, 1971) focuses on separation distress, the disturbance that occurs when an individual is separated from the attachment object. This, coupled with the positive feeling of reinforcement when reunited, motivates the individual to try to maintain proximity with the attachment object.
Describe the Development of Social Behavior in Childhood (Objective 7)
30. The period roughly between the ages of 2 and 11 is usually considered to be childhood .
31. Overcoming their earlier self-centeredness, children at age 4 or 5 begin to identify with their parents. They see themselves as being like their parents and begin to imitate their characteristic ways of behaving.
32. Research indicates that when developing a self-concept , young children focus on external characteristics such as their name and age, whereas older children emphasize internal qualities such as cognitive abilities and personality.
33. Selman and Selman (1979) found that very young children label any children they play with as friends . At age 9, children define friends as those who do what they want, and older children develop mutually satisfying friendships.
34. Sigmund Freud theorized that from birth to adolescence, children go through five developmental periods, called psychosexual stages.
35. The first psychosexual stage, during which the baby receives pleasure from sucking, is called the oral stage. Children from 2 to 4 years are in the anal stage, during which the first restrictions on impulses are imposed.
36. The psychosexual stage that begins at about 4 years of age when the child starts to find pleasure in stimulating the genitals, is the phallic stage. The psychosexual stage between 6 years and puberty, during which the child appears to have little need for erotic satisfaction, is called the latency stage.
37. The psychosexual stage that begins at sexual maturity during which the individual can begin to relate in a positive sexual way toward other people is the genital stage.
Identify the Concepts Presented in Piaget's Theory of Cognitive Development (Objective 8)
38. Piaget believed that cognitive development occurred in a child because the developing mental structures were challenged by events that the child observed in the environment.
39. In order to overcome a problem, the child has to develop more complex cognitive structures, or schemes . This may be thought of as a unit of knowledge that a person possesses, or a mental picture of the world.
40. According to Piaget, the process by which the child integrates new stimulus events into already existing schemes (mental pictures of the world) is called assimilation .
41. Sometimes the child cannot assimilate the new stimulus into existing schemes. The process of creating a new scheme or changing an existing scheme to make room for a new stimulus event or experience is called accommodation .
Describe the Periods in the Piaget's Cognitive Development Theory (Objective 9)
42. Piaget's first period (from birth to 2 years), during which the infant spends a great deal of time learning to coordinate sensory experiences with motor activities, is called the sensorimotor period.
43. During the sensorimotor period, the infant develops the ability to realize that objects continue to exist even though they might not always be seen, an ability called object permanence .
44. Piaget's second period (from age 2 to 7 years), during which the child acquires language and learns to represent the environment with objects and symbols, is called the preoperational thought period.
45. Children in the preoperational period see themselves as the center of their universe, a characteristic called egocentrism .
46. Piaget's third period (from age 7 to 11 years), during which the child develops conservation, decentration, reversal and the ability to solve problems with logical reasoning, is called the concrete operations period.
47. The ability to recognize that properties of objects do not change even though their appearance does, is called conservation .
48. Piaget's fourth stage (from age 11 to 15 years), during which the adolescent reaches cognitive maturity and is capable of abstract logical thinking and hypothesis testing, is called the formal operations period.
Outline Kohlberg's Theory of Moral Development (Objective 10)
49. Kohlberg (1969) studied the development of the awareness of ethical behavior, or moral development . Kohlberg proposed that the way a child reasons about right and wrong develops according to a specific pattern.
50. Kohlberg's Level I, a period in which moral reasoning is based largely on expectation of rewards or punishments, is called preconventional morality.
51. Kohlberg's Level II, a period in which moral reason is based largely on conformity and social standards, is called conventional morality.
52. Kohlberg's Level III, a period in which moral reasoning is based largely on personal standards and beliefs, is called postconventional morality.
Outline Physical Development in Adolescence (Objective 11)
53. The stage of development between the onset of puberty and about 18 to 21 years, is called adolescence .
54. Adolescence is closely associated with the onset of puberty , or sexual maturation.
55. Menarche, or the onset of menstruation, is a sign of puberty in girls age 11 to 14. The development of secondary sex characteristics, such as breasts, pubic hair and broadened hips, indicates she is ready to reproduce.
56. In boys, the testes and penis begin to grow at 12 to 13 years, indicating puberty . Male secondary sex characteristics include development of beards, lower voice, broadened shoulders, and pubic hair.
Identify Major Areas of Personality and Social Development in Adolescence (Objective 12)
57. A major goal in adolescence, according to Erikson, is development of a personal identity .
58. Marcia (1980) believed that adolescents who have struggled with values and have made a commitment to some personal goal have reached identity achievement .
59. Gilligan suggested that males develop identity based on individual achievement and females develop identity based on social relationships.
60. Hays (1985) suggested that male friendships develop more from shared activities, whereas female friendships develop from verbal communication.
Describe Erikson's Psychosocial Theory of Development (Objective 13)
61. In Erikson's Stage 1, trust versus mistrust, the person in infancy should develop a sense that others will help him and not do him harm.
62. In Erikson's Stage 2, autonomy versus doubt, the person in early childhood has the potential to develop a sense of independence, a knowledge of the capability to take actions independently of other people.
63. In Erikson's Stage 3, initiative versus guilt, the person in childhood should develop a sense of initiative, and the ability to begin projects guided by a developing conscience.
64. In Erikson's Stage 4, industry versus inferiority, the child in school has to learn competence and persistence at certain activities he may not like.
65. In Erikson's Stage 5, identity versus role confusion, the adolescent faces the problems of personal identification.
66. In Erikson's Stage 6, intimacy versus isolation, the young adult faces the challenge of integrating one's life with that of someone else, usually in marriage.
67. In Erikson's Stage 7, generativity versus self- absorption, the mature person faces the challenge of establishing goals, commitments, absorption and lasting attachments that permit a reasonable balance between productivity and stagnation.
68. In Erikson's Stage 8, integrity versus despair, the person in old age realizes that he has to accept his life as it has been, with disappointments as well as joys.
Outline Physical Development in Adulthood (Objective 14)
69. Physical aging becomes noticeable during middle adulthood, as we experience changes in skin, respiration, cardiovascular activity, and the sense organs. Menopause occurs in women at about age 50.
70. The theory of Hayflick (1980) that human body cells are programmed to reproduce themselves a finite number of times is called the theory of cellular aging.*
Identify the Major Milestones of Adult Personality and Social Development (Objective 15)
71. Levinson's life structure personality theory includes four seasonal cycles: preadulthood, early adulthood, middle adulthood, and late adulthood.*
72. Much of our adult life centers around family and jobs. As a main theme of young adulthood, intimacy or marriage is an important milestone for most adults.
73. People need to be engaged in some worthwhile activity as adults, and thus a job or occupation is important.
74. A major transition in life, involving both family and job, occurs when a person retires , which reminds us that we are getting older and will eventually die.
75. Atchley's (1985) model of retirement includes the phases of preretirement, honeymoon, disenchantment, reorientation, stability, and terminal.*
Outline Cognitive Development in Adulthood (Objective 16)
76. There are cultural variations in the intellectual expectations of older persons. Evidence suggests that Cognitive functioning significantly declines once a person is past the age of 80.
Outline the Psychological Stages of Dying (Objective 17)
77. Kbler-Ross described five stages that people usually go through as they die. In the first stage, denial , people believe the doctor made a mistake and that it is not possible that they could actually be dying.
78. In the second stage of dying, anger , people realize that they will die and become resentful of the people around them. In the third stage, bargaining, people try to buy time by making a deal with doctors, family and God.
79. In the fourth stage of dying, depression , the people recognize the inevitable fact that they are going to die. In the fifth stage, acceptance, people are able to quietly make the necessary preparations for death.
