Studying Development
Developmental Psychology: Studies age-related changes in behavior & mental processes from conception to death

Studying Development– Key Theoretical Debates
Nature vs. Nurture: Heredity vs. environment
Continuity vs. Stages: Continuous & gradual vs. periods of abrupt change followed by periods of little change
Stability vs. Change: Characteristics maintained vs. characteristics vary over time

Studying Development (Continued)
Social
What position on these three debates is most correct? Most psychologists support the interactionist perspective, which recently evolved into the biopsychosocial model. Psychological
Biological

Pause & Reflect: Critical Thinking
Behaviorist John Watson said: “Give me a dozen healthy infants, well-formed, & my own specified world to bring them up in, & I'll guarantee to take anyone at random & train them to become any type of specialist I might select-- doctor, lawyer, artist, merchant-chief, &, yes, even beggar man & thief, regardless of his talents, penchants, tendencies, abilities, vocations, & race of his ancestors." (Boakes, 1984, pp. 226) Do you agree? Why or why not?

Cultural Guidelines for Developmental Research
Culture may be the most important determinant.
Development cannot be studied outside its sociocultural context.
Each culture’s ethnotheories are important determinants.
Culture is largely invisible to participants.

Pause & Reflect:
Assessment
1. Can you briefly describe the three key areas of debate in developmental psychology?
2. What are the key differences between cross-sectional & longitudinal research?

Physical Development—The Moment of Conception
©John Wiley & Sons, Inc. 2010
Physical Development—Three Stages of Prenatal Development
1. Germinal Period: Conception to uterine implantation
2. Embryonic Period: Uterine implantation through the eighth week
3. Fetal Period: Eighth week until birth

Physical Development—Three Stages of Prenatal Development
©John Wiley & Sons, Inc. 2010
Physical Development—Hazards to Prenatal Development
Teratogens: Environmental agents that cause damage during prenatal development
• Categories of teratogens:– Legal & illegal drugs– Diseases & malnutrition– Exposure to X-rays & stress

Physical Development—Hazards to Prenatal Development

Physical Development—Early Childhood
Three key areas of early childhood development: Brain Motor Sensory/perceptual

n Physical Development—Prenatal Brain Development
©John Wiley & Sons, Inc. 2010
Physical Development—Brain Development
• As a child develops, his or her neurons grow in size & the number of dendrites & axons increase.
©John Wiley & Sons, Inc. 2010
Physical Development- Lifespan Changes in Body Proportions
©John Wiley & Sons, Inc. 2010
Physical Development—Early Childhood
• Milestones in motor development
©John Wiley & Sons, Inc. 2010
Physical Development—Sensory & Perceptual Development
• Smell, taste, touch, & hearing are well developed at birth.
• Vision is poorly developed at birth.
©John Wiley & Sons, Inc. 2010
Physical Development—Adolescence & Puberty
©John Wiley & Sons, Inc. 2010
Physical Development- Adulthood
Middle Age: • Female Menopause • Male Climacteric
Late Adulthood:• Primary Aging:
gradual, inevitable changes versus age changes due to disease, disuse, or neglect
©John Wiley & Sons, Inc. 2010
Pause & Reflect:
Assessment
1. _____ are environmental agents that may lead to birth defects.
2. The senses of _____, ______, _____, & _____ are all well developed at birth.
©John Wiley & Sons, Inc. 2010
Cognitive Development
Jean Piaget believed infants begin at a cognitively “primitive” level & progress in distinct stages.
Piaget’s schemas are the most basic unit of intellect, which act as patterns that organize interactions with the environment.
©John Wiley & Sons, Inc. 2010
Cognitive Development (Continued)
Schemas grow & change due to:
Assimilation: Absorbing new information into existing schemas
Accommodation: Adjusting old schemas or developing new ones to better fit with new information
©John Wiley & Sons, Inc. 2010
Cognitive Development (Continued)
Can you draw this “impossible figure”? If not, it’s likely that you have not developed the required artistic schema.

Cognitive Development—Piaget’s Four Stages
Sensorimotor: Birth-2 years Preoperational: 2-7 years Concrete Operational: 7-11 years Formal Operational: 11 years & up

Assessing Piaget’s Theory—Two Major Criticisms
1. Underestimated abilities (e.g., newborns can imitate facial expressions)
2. Underestimated genetic & cultural influences
©John Wiley & Sons, Inc. 2010
Pause & Reflect:
Assessment
1. _____ act as patterns that organize interactions with the environment.
2. Assimilation occurs when _____, whereas accommodation involves _____.
©John Wiley & Sons, Inc. 2010
Social-Emotional Development
Social Development Attachment: Strong
affectional bond with special others that endures over time Harlow’s work with
monkeys--feeding or contact comfort?
©John Wiley & Sons, Inc. 2010
Social-Emotional Development—Three Levels of Attachment
Ainsworth’s strange situation procedure identified three types of attachment in children:
1. Securely Attached Child stays close to mother, shows moderate distress when separated, & is happy when mother returns.
©John Wiley & Sons, Inc. 2010
2. Avoidant: Child treats mother & stranger the same & rarely cries when mother leaves.
3. Anxious/Ambivalent: Child is upset when mother leaves. When mother returns, child seeks closeness, but also squirms away.
Three Levels of Attachment (Continued)

Pause & Reflect: Psychology at
Work
Research suggests the attachment patterns we develop as infants may carry over into similar patterns in our adult romantic relationships.

Social-Emotional Development—Baumrind’s Three Parenting Styles
1. Permissive (Permissive-Neglectful & Permissive-Indulgent)
2. Authoritarian
3. Authoritative Identified by degree of
control/demandingness (C) & warmth/ responsiveness (W)
©John Wiley & Sons, Inc. 2010
Social-Emotional Development—Baumrind’s Three Parenting Styles
1. Permissive
a.Permissive-Neglectful Few limits or control (Lo C), little warmth or responsiveness (Lo W)
b.Permissive-Indulgent Few limits or control (Lo C), high warmth & responsiveness (Hi W)
©John Wiley & Sons, Inc. 2010
Baumrind’s Three Parenting Styles (Continued)
2. Authoritarian Highly controlling (Hi C), little warmth or responsiveness (Lo W)
3. Authoritative Set & enforce firm limits (Hi C), high warmth or responsiveness (Hi W)
Study Tip: Two “Rs” in
AuthoRitaRian = “Rigid Ruler!”
Two “Ts” in AuThoriTative = “Tender Teacher!”
