1 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood Module 17 Infancy & Childhood

2 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood PRENATAL INFLUENCES Prenatal period: three stages –prenatal period extends from conception to birth and lasts about 266 days (9 months)

3 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood PRENATAL INFLUENCES (CONT.) Prenatal period: three stages 1.Germinal stage –conception or fertilization –occurs if one of the millions of sperm penetrates the ovum’s outer membrane –after penetration by the sperm, outer membrane changes and becomes impenetrable to the millions of remaining sperm –fertilized ovum is called “zygote”

4 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood PRENATAL INFLUENCES (CONT.) Prenatal period: three stages 2.Embryonic stage –second stage of the prenatal period and spans the 2-8 weeks that follow conception –during this stage, cells divide and begin to differentiate into bone, muscle, and body organs

5 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood PRENATAL INFLUENCES (CONT.) Prenatal period: three stages 3.Fetal stage –begins two months after conception and lasts until birth –fetus develops vital organs, such as lungs, and physical characteristics that are distinctly human –during embryonic and fetal stages, the developing organism is especially vulnerable to toxic agents –protected by the placenta

6 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood PRENATAL INFLUENCES (CONT.) Placenta and teratogens –Placenta organ that connects the blood supply of the mother to that of the fetus acts like a filter allows oxygen and nutrients to pass through while keeping out some toxic or harmful substances –Teratogen any agent that can harm a developing fetus (cause deformities or brain damage) can be a disease, drug, or another environmental agent

7 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood PRENATAL INFLUENCES (CONT.) Birth defects and amniocentesis –possible to test during fetal stage for a number of genetic errors –Amniocentesis medical test done between weeks 14 and 20 of pregnancy involves inserting a long needle through the mother’s abdominal muscles into the amniotic fluid surrounding the fetus fetal cells are analyzed in the fluid more than 450 genetic disorders can now be tested and identified

8 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood PRENATAL INFLUENCES (CONT.) Birth defects and amniocentesis –Down Syndrome results from extra 21 st chromosome causes abnormal physical traits fold of skin at the corner of each eye, wide tongue, heart defects abnormal brain development, resulting in degrees of mental retardation

9 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood PRENATAL INFLUENCES (CONT.) Drugs and prenatal development –Drug use during pregnancy cocaine plus other drugs pregnant women using crack cocaine along with other drugs, such as alcohol, tobacco, marijuana, or opiates had: –lower birth weight –poor feeding habits –greater risk for developing other psychological problems

10 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood PRENATAL INFLUENCES (CONT.) Drugs and prenatal development –Drug use during pregnancy smoking and nicotine 13% (about) of pregnant women smoke increase the risk of: –low birth weight –pre-term deliveries –possible physical problems (cleft lip or palate) –SIDS –respiratory infections

11 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood PRENATAL INFLUENCES (CONT.) Drugs and prenatal development –Drug use during pregnancy lead levels of lead in the blood system are associated with low IQ scores in children likelihood of antisocial acts such as, assaults, truancy, and disorderly conduct some lead sources, paint, gasoline, industry

12 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood PRENATAL INFLUENCES (CONT.) Drugs and prenatal development –Drug use during pregnancy alcohol heavy drinking - Fetal Alcohol Syndrome (FAS) FAS results from a mother drinking heavily during pregnancy, especially in the first 12 weeks FAS results in: –short stature, flattened nose, short eye openings, neurological changes, hyperactivity, impulsive behavior, deficits in information processing, drug and alcohol abuse

13 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood PRENATAL INFLUENCES (CONT.) Drugs and prenatal development –Drug use during pregnancy alcohol moderate drinking - Fetal Alcohol Effects (FAE) FAS results from a mother having 7-14 drinks per week during pregnancy FAE less severe than FAS FAE results in: –Deficiencies in cognitive tasks, academic skills, fine motor speed and coordination

14 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood NEWBORNS’ ABILITIES Genetic development program –mother contributes 23 chromosomes and father contributes 23 chromosomes –each child receives a unique genetic program –brain growth –genetic program (after birth) regulates how the brain develops –makes thousands of connections between neurons

15 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood NEWBORNS’ ABILITIES (CONT.) Sensory development –Faces newborns show a preference for their mother’s face over strangers faces the first few days after birth newborns recognize a person’s eyes 3-6 months –infant can visually distinguish his or her mother’s face from strangers 3-4 years –visual abilities are equal to those of an adult

16 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood NEWBORNS’ ABILITIES (CONT.) Sensory development –Hearing one-month olds have very keen hearing can discriminate small sound vibrations 6 months, have developed the ability to make all sounds that are necessary to learn language –Touch have well developed sense of touch will turn head when lightly touched on the cheek touch also elicits other reflexes such as grasping and sucking

17 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood NEWBORNS’ ABILITIES (CONT.) Sensory development –Smell and taste infants at 1-day-old can discriminate a few odors such as citrus and floral six-week-old infants can smell the difference between their mother and a stranger newborns have an inborn preference for both sweet and salt and an inborn dislike of bitter- tasting things depth perception At 6 months, infants have developed depth perception

18 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood NEWBORNS’ ABILITIES (CONT.) Motor development –refers to the stages of motor skills that all infants pass through as they acquire the muscular control necessary for making coordinated movements –Proximodistal principle states that parts closer to the center of the infant’s body develop before parts farther away –Cephalocaudal principle states that parts of the body closer to the head develop before parts closer to the feet

19 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood NEWBORNS’ ABILITIES (CONT.) Motor development –Maturation refers to developmental changes that are genetically or biologically programmed rather than acquired through learning or life experiences –Developmental norms refers to the average age at which children perform various kinds of skills or exhibit abilities or behaviors major milestones in infants’ motor development crawling, walking

20 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood NEWBORNS’ ABILITIES (CONT.) Motor development –environmental stimulation appropriate stimulation for development of the visual system, for learning to speak, for emotional development, and for motor development infants cannot perform complex cognitive, sensory or motor tasks, such as walking, talking, and reading until appropriate areas of their brains develop neural connections genetic program needs and interacts with environmental stimulation for the proper development of a child’s sensory, motor, and cognitive abilities

21 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood EMOTIONAL DEVELOPMENT Definition –refers to the influence and interaction of genetic factors, brain changes, cognitive factors, coping abilities, and cultural factors in the development of emotional behaviors, expressions, thoughts and feelings Temperament and emotions –refers to relatively stable and long lasting individual differences in mood and emotional behavior, which emerge early in childhood because these differences are largely influenced by genetic factors

22 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood EMOTIONAL DEVELOPMENT (CONT.) Temperament and emotions –Easy babies happy and cheerful, regular sleeping and eating habits, adapted quickly to new situations –Slow-to-warm-up babies more withdrawn, moody, and tend to take longer to adapt to new situations –Difficult babies fussy, fearful of new situations, and more intense in their reactions

23 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood EMOTIONAL DEVELOPMENT (CONT.) Temperament and emotions –No-single-category babies variety of traits and cannot be classified into one of the other three categories –Genetic influence infants develop distinct temperaments very early, usually in the first 2-3 months of life these distinct temperaments occur largely because of genetic factors rather than learning experiences

24 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood EMOTIONAL DEVELOPMENT (CONT.) Temperament and emotions –Environmental influence involves factors such as, family influence, poverty level, educational opportunities, and social class interact with and can change the infant’s initial temperament –Attachment a close, fundamental emotional bond that develops between the infant and his or her parents or caregiver as a child shows closer attachment to parents, the child shows more distress when the parents temporarily leave

25 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood EMOTIONAL DEVELOPMENT (CONT.) Attachment –Separation anxiety an infant’s distress whenever the infant’s parents leave Kinds of attachments –Secure attachment characteristic for infants who use their parent as a safe home base from which they can wander off and explore their environments –Insecure attachment characteristic of infants who avoid or show ambivalence or resistance toward their parent or caregiver

26 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood EMOTIONAL DEVELOPMENT (CONT.) Attachment –Effects of attachment –kind of attachment formed in infancy is thought to be associated with the success of future adult relationships –Secure attachment associated with being better at resolving conflicts, being more trusting, enjoying relationships, and dealing better with stress and anxiety –Insecure attachment associated with being dependent, having poor social relationships, and showing more anxiety in stressful settings

27 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood COGNITIVE DEVELOPMENT Piaget’s theory –Cognitive development refers to how a person perceives, thinks, and gains an understanding of his or her world through the interaction and influence of genetic and learned factors –Jean Piaget greatest impact on developmental psychology with cognitive development both biologist and psychologist

28 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood COGNITIVE DEVELOPMENT Piaget’s theory –Assimilation process by which a child uses old methods or experiences to deal with new situations –Accommodation process by which a child changes old methods to deal with or adjust to new situations

29 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood COGNITIVE DEVELOPMENT (CONT.) Piaget’s stages of cognitive development –Refer to four different stages 1.Sensorimotor stage 2.Preoperational stage 3.Concrete operations 4.Formal operations

30 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood COGNITIVE DEVELOPMENT (CONT.) Sensorimotor Stage –birth to age 2 –infants interact with an learn about their environments by relating their sensory experiences to their motor experiences –object permanence –develops over a period of 9 months –refers to the understanding that objects or events continue to exist even if they can no longer be heard, touched or seen

31 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood COGNITIVE DEVELOPMENT (CONT.) Preoperational Stage –about age 2 to 7 years –children learn to use symbols, such as words or mental images, to solve simple problems and to think or talk about things that are not present –Conservation refers to the fact that even though the shape of some object or substance is changed, the total amount remains the same –Egocentric thinking refers to seeing and thinking of the world only from your own viewpoint and having difficulty appreciating someone else’s viewpoint

32 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood COGNITIVE DEVELOPMENT (CONT.) Concrete Stage –about age 7 to 11 years –children can perform a number of logical mental operations on concrete objects (physically present) –Conservation children gradually master the concept of conservation during the concrete operations stage –Classification ability to classify items by color and size for example children still have difficulty figuring out relationships among objects that are not present or imaginary situations

33 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood COGNITIVE DEVELOPMENT (CONT.) Formal Operations Stage –about age 12 to adulthood –adolescents and adults develop the ability to think about an solve abstract problems in a logical manner –adolescents develop thinking and reasoning typical of adults –ability to think in a logical, systematic, and abstract way is one of the major characteristics of the formal operations stage

34 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood SOCIAL DEVELOPMENT Social development –refers to how a person develops a sense of self or a self-identity, develops relationships with others, and develops the kinds of social skills important in personal interactions Freud’s Psychosexual Stages –Five different developmental periods: 1.Oral 2.Anal 3.Phallic 4.Latency 5.Genital

35 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood SOCIAL DEVELOPMENT (CONT.) Oral stage –early infancy to 18 months –pleasure seeking is around the mouth –sucking,chewing, and biting –if fixated at this stage due to oral wishes being gratified too much or to little, could continue in adulthood seeking oral gratification

36 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood SOCIAL DEVELOPMENT (CONT.) Anal stage –1 and a half years to 3 years –infant’s pleasure seeking is centered on the anus and its functions of elimination –if fixated, will continue behavior activities in either retention or elimination –retention –may take form of being neat, stingy, or rigid –elimination –may take form of being generous or messy

37 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood SOCIAL DEVELOPMENT (CONT.) Phallic stage –3 to 6 years (early childhood) –pleasure seeking is centered on the genitals –competes with parent of same sex for affections and pleasures of the parent of the opposite sex –may result in feelings of inferiority for women and of having something to prove for men

38 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood SOCIAL DEVELOPMENT (CONT.) Latency stage –6 to puberty (middle to late childhood) –child represses sexual thoughts and engages in nonsexual activities, such as: –developing social and intellectual skills –puberty: –sexuality reappears

39 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood SOCIAL DEVELOPMENT (CONT.) Genital stage –puberty to adulthood –individual has renewed sexual desires that he or she seeks to fulfill through relationships with members of the opposite sex –successful resolution of the conflicts in the first three stages will lead to having energy to develop loving relationships and a healthy and mature personality

40 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood SOCIAL DEVELOPMENT (CONT.) Erikson’s Psychosocial Stages –eight developmental periods during which an individual’s primary goal is to satisfy desires associated with social needs –Eight periods associated with issues of: 1.Trust 2.Autonomy 3.Initiative 4.Industry 5.Identity 6.Intimacy 7.Generativity 8.Ego integrity

41 Introduction to Psychology, 7th Edition, Rod Plotnik Module 17: Infancy & Childhood SOCIAL DEVELOPMENT (CONT.)
