Q

Each stage of child development will be looked at with respect to the following categories:

A

• Physical:
The contributions of physical abilities to development (i.e., crawling, walking, reaching)

• Cognitive: How children learn and what they know (stages of mental growth, IQ, testing, language, etc.)

• Emotional & Social Domains:
Emotions, how children deal with their emotions, and a child’s ability to socialize with adults and children (developing bonds with parents, friendships, building self-awareness, etc.)

Q

Stage theorists assume that people follow the same sequence of development, but is that really true…?

A

Even children from a single family can turn out very differently based on:
— Genetic differences
— Differences in treatment by parents and others
— Differences in reactions to similar experiences
— Differences in choice of environment

Q

Contributions of Nature and Nurture

Example

A

Development of a strong conscience at age 5 is associated with gentle maternal discipline in children with a fearful temperament

For fearless children, though, a close relationship with the mother is associated with a strong conscience (regardless of discipline)

Q

Early Philosophical Ideas:

Plato & Aristotle

A

The long-term welfare of society depends on children being raised properly.

“Now of all wild things, a boy is the most difficult to handle. Just because he more than any other has a fount of intelligence in him which has not yet run clear he is the crakiest, most mischievous, and unruliest of brutes.” - Plato

“It would seem then that a study of individual character is the best way of making education perfect, for then each [child] has a better chance of receiving the treatment that suits him.” - Aristotle

Q

John Locke

1632-1704

A

Tabula Rasa: Latin for “Blank Slate”

Growth of Character

Parents set good examples of honesty, stability, and gentleness

Avoid Indulging: So as not to spoil. Introduce freedom slowly.

“I Imagine the mind of children as easily turned, this or that way as water itself.”

Forerunner of Behaviorism, nurture determines everything

Continuous Development, Many paths of development, high plasticity,

Noble savages: He believed that children are endowed with a sense of right and wrong

Built in moral sense

Adult receptivity

Rousseau introduced the concept of stages of development

He also introduced the concept of Maturation: the genetically determined, naturally unfolding course of growth

A

behavior is motivated by inner forces, memories, and conflicts of which a person has little awareness or control

Psychoanalytic: Freud

Psychosocial: Erikson

Discontinuous:
distinct stages of development

One course:
stages are assumed to be universal

Both Nature & Nurture:
innate impulses are channeled and controlled through child-rearing experiences

Q

The 3 Parts of Yourself,

According to Freud

A

Id: Birth
– Earliest and most primitive of 3 personality structures.
– “The dark, inaccessible part of our personality… a cauldron full of seething excitations in need of satisfaction”
– The Pleasure Principle: goal of achieving maximal gratification maximally quickly

Ego: Around Age 1
– “Stands for reason and good sense”
– The Reality Principle: we find ways to satisfy the Id that accord with the demands of the real world

Superego: between Ages 3 and 6
– Internalized rules
– Conscience

Q

The Stages of PsychoSexual Development

A

Oral: Birth – 1 year
– Primary source of gratification and pleasure is oral activity.
– “If the infant could express itself, it would undoubtedly acknowledge that the act of sucking at its mother’s breast is far and away the most important thing in life” - Freud
– Issue: Premature weaning

Anal: 1–3 years
– Children’s erotic interests focus on the pleasurable relief of the tension derived from defecation.
– Issue: Toilet training handled correctly?

Phallic:  3–6 years
– Children interested in own genitals
– Boys take an interest in their penis, “so easily excitable and changeable and so rich in sensation” – Freud
– Girls develop penis envy
– Issue: Oedipus Complex

Latency: 6–11 years
– Out of sex business: sex is repressed until adolescence

Q

Theory of PsychoSocial Development:

The Stages

A

Birth–1 yr: Basic Trust vs. Mistrust
– “an essential trustfulness of others as well as a fundamental
sense of one’s own trustworthiness” -Erikson
– Mother must be warm, consistent, and reliable in her caregiving.

Ages 1-3.5 years: Autonomy vs. Shame & Doubt
– Dramatic changes occur in children’s abilities; Battle of wills
– Parental support allows children to gain self-control autonomy forms
– Parental punishment result in children feeling shame

Ages 4-6 yrs: Initiative vs. Guilt
– “the child hitches his wagon to nothing less than a star: he wants to be like his parents, who to him appear very powerful and very beautiful” -Erikson
– Attain a Conscience (internalized rules & standards)
– If parents are not too controlling, children develop high
standards and initiative without being crushed

Ages 6 to puberty: Industry vs. Inferiority
– Successful experiences give the child a sense of competence, but failures might lead the child to feel inadequate

Q

Behaviorism & Social Learning Theories:

A

All emphasize continuity, proposing that the same principles control learning & behavior throughout life

Many possible courses of development, not just one path.

Nurture mostly, not nature

35
Q

Pavlov’s Dog

A

– Dogs salivate as an innate reflex when given food

– Pavlov noticed that his dogs salivated before tasting any
food but immediately as the trainer arrived

– Pavlov reasoned the dogs must have associated a neutral stimulus (the trainer) with another stimulus (food) to produce salivation

Behaviorism & Social Learning Theory

hdps://www.youtube.com/watch?v=hhqumfpxuzI

36
Q

John Watson

A

1878–1958

Founder of behaviorism

Believed that child development is determined completely by the social environment

Continuous development

Demonstrated the power of classical conditioning in a famous experiment with “Little Albert”
– Exposed 9-month-old Albert to a nice rat in the laboratory which elicited a positive reaction from Albert
– On subsequent exposure, Watson used a loud noise to frighten Albert
– Eventually Albert became afraid of the rat itself
– https://www.youtube.com/watch? v=KxKfpKQzow8&feature=related

“Give me a dozen healthy infants, well-formed, and my own specified world to bring them up in and I’ll guarantee to take any one at random and train him to become any type of specialist I might select – doctor, lawyer, artist, merchant- chief and even beggar and thief, regardless of his talents, penchants, tendencies, abilities, vocations, and race of his ancestors.” -Watson

37
Q

Systematic Desensitization

A

Classical conditioning can also be used to eliminate fear

2-year-old Peter was deathly afraid of rabbits.
– To decondition his fear, the experimenter gave him
a favorite snack
– As Peter ate, the rabbit was gradually brought closer
– hdps://www.youtube.com/watch?v=Nkd7zcvFQ5w, time 3:39

38
Q

B.F. Skinner

A

1904 – 1990

“A person does not act upon the world, the world acts upon him.” – Skinner

Operant Conditioning:
– Repeat behaviors that lead to favorable outcomes
(reinforcement)
– Suppress behaviors that result in unfavorable outcomes (punishment)

– hdps://www.youtube.com/watch?v=D-RS80DVvrg

39
Q

Operant Conditioning:

Reinforcement vs. Punishment

A

Punishment: Decreases Behavior
Positive Punishment: add noxious stimuli following bad behavior (spanking for lying).

Reinforcement: Increase Behavior
Positive Reinforcement: Add appetitive stimulus following correct behavior (giving a sitting dog a treat).
Escape: Remove noxious stimuli following correct behavior (turning off a ringing alarm clock after waking up).

40
Q

Skinner’s Discoveries

A

Parental attention to poor child behavior only reinforces the behavior.
– Children often do things “just to get attention”
– Parental solution: Ignore behavior

Difficulty of extinguishing behaviors that had been intermittently reinforced.
– Intermittent reinforcement makes behaviors resistant to extinction
– Parental solution: Be consistent, even giving in to whining once can lead to bad habits

41
Q

Albert Bandura

A

Social Learning Theory
– Emphasizes observation and imitation as the primary mechanism of development

Observational learning depends on…	
– Attention		
– Encoding		
– Storing	
– Retrieving
42
Q

Bandura and Bobo

A

Preschool children individually watch a short film in which an adult model performed highly unusual aggressive actions on a Bobo Doll
– 33.3% watched model be rewarded
– 33.3% saw model punished
– 33.3% saw model experience no consequences

RQ: Does vicarious reinforcement affect the child’s subsequent behavior?

The children who had seen the model punished imitated the behavior less than did those in the other two groups

However when offered a reward to reproduce the aggressive behavior, they did so

hdps://www.youtube.com/watch?v=zerCK0lRjp8

43
Q

Bandura’s Revised Version

A

Children gradually become more selective in what they imitate.

Children observe others’ self-praise, self-blame, and feedback
– Develop personal standards
– Self-efficacy

“I’m glad I kept working on that task, even though it was hard.”

“I know you can do a good job on that homework.”

44
Q

Social Learning Theory

Critiques & Contributions

A

Contribution:
Applied behavior analysis –
eliminate undesirable behaviors and increase desirable responses via conditioning & modeling

Limitations:
– Too narrow of a view of important environmental influences
– Underestimating the child’s contribution
– Children in Bobo experiment were manipulated and pressured
– Implies causation

45
Q

Piaget’s Cognitive-Developmental Theory

A

“When you teach a child something, you take away forever his chance of discovering it for himself.” –Piaget

Cognitive development takes place in stages

One course of development: Changes studied characterize most or all children

Both Nurture and Nature
Development occurs as the brain grows and children exercise their innate drive to discover reality in a generally stimulating environment. Both early and later experiences are important.

Greatly influenced by Piaget’s background in biology

Adaptation: structures of the mind develop to better fit with or represent the external world

Believed young children’s thinking was full of faulty logic

Equilibrium = balance between internal structures and information in real world

46
Q

Jean Piaget

A

1896–1980

Swiss psychologist who emphasized children as active agents

Believed children actively construct knowledge as they manipulate and explore their world

Did not receive attention until 1960s

47
Q

Piaget’s Stages of Development

Cognitive-Developmental Theory

A

Sensorimotor Stage: (birth–2yrs)
– Think by acHng on the world…
– Reflexes develop into systemaHc behaviors

PreOperational Stage: (2–7yrs)
– Use symbols to represent earlier sensorimotor discoveries.
– Language and make believe occur.

Concrete Operations: (7–11yrs)
– Reasoning becomes more logical and better organized
– Achieve conservation

Formal Operations: (11–15 yrs)
– Abstract, systematic thinking takes place
– Children can hypothesize, test inferences, and isolate & combine variables

48
Q

Piaget’s Contributions & Limitations

A

Piaget’s theory encouraged the development of educational philosophies & programs that emphasize children’s discovery learning and direct contact with the environment.

Some say Piaget underestimated the abilities of young children (e.g. some young children were able to problem solve in ways similar to older children).
– With training, children perform better
– Does not account for cultural differences

49
Q

Cognitive Perspective

A

Information-Processing Approach.
Mind as a computer.
Input and Output. OrganizaTION, STORAGE, Memory

Example:
Child: “Daddy would you unlock the basement door?”
Father: “Why?”
Child: “Because I want to ride my bike.”
Father: “Your bike is in the garage.”
Child: “But my socks are in the dryer.”

Top goal: Ride back
Bias: I need shoes to be comfortable
Fact: I’m barefoot
Subgoal 1: Get my sneakers
Fact: The Sneakers are in the yard
Fact: They’re uncomfortable on barefeet
Subgoal 2: Get my socks
Fact: The sock drawer was empty this morning.
Inference: The socks must be in the dryer
Subgoal 3: Ask daddy to unlock basement door

Cognitive Neuroscience Approach
– Brain processes
– How do infants gain perception of facial expressions?
– Neurological basis of autism

Q

Recent Theoretical Perspectives:

Contextual Theories

A

Ethology & Evolutionary Developmental Psychology

Bioecological Approach – Bronfenbrenner

Sociocultural Theory – Vygotsky

Dynamic Systems Perspective

51
Q

Contextual Theories:

Ethology & Evolutionary Psychology

A

Behavior is the result of genetic inheritance from ancestors, and environmental interactions

Ethology: What is the survival value of a particular behavior

Konrad Lorenz (imprinting)

Critical Time Period: child is prepared to acquire adaptive behaviors

52
Q

Contextual Theories:

Sociocultural Theory

A

How culture (the values, beliefs, customs, skills of a social group, etc.) is transmitted to the next generation.

Social interaction is imperative to transfer
this knowledge.

Vygotsky agreed with Piaget that children
are active, constructive beings, but viewed
cognitive development as a socially mediated process.

Acknowledged that what we learn at a given age is a result of the values and needs of the culture in which we live.

53
Q

Contextual Theories:

Ecological Theory

A

Urie Bronfenbrenner

Bioecological Approach

54
Q

Contextual Theories:

Dynamic Systems Perspective

A

Aspects of child (motor skills, language, perception) must function as an integrated whole to produce behavior

The child must actively reorganize his/her behavior so the components can work together again.

55
Q

Scientific Method

A

All beliefs, no matter how probable, might be wrong.

The scientific method involves 4-5 basic steps:
– Choosing a question grounded in theory
– Formulating a hypothesis
– Developing a method for testing
– Using the data yielded by the method to draw a conclusion about the hypothesis
– Revise theory

56
Q

The 4 Main Research Methods

A
How does the researcher go about answering the main research question?
– Systematic Observation
– Self-Reports
– Clinical Method
– Ethnography
57
Q

Systematic Observation

A

Naturalistic Observation:
Observing the desired behavior in the subject’s own environment

Structured Observation:
Situation is manipulated in some way that might yield a particular response

58
Q

Self-Reports

A

Unstructured:

  • Interview
  • Open-Ended Questions

Structured:

  • Survey
  • Interview

Clinical Interview: A flexible, conversational style used to probe for the participant’s point of view.

Structured Interview: Participants are asked the same question in the same way.

59
Q

Case Study Method

A

brings together a wide range of information on one child, including interviews, observations, and sometimes scores

– “Complete Package”
– Research conducted on child prodigies (Ruthsatz & Urbach, 2012)
– School psychologists
– Intervention specialists

60
Q

Ethnography

A

Ethnography = descriptive, qualitative technique directed toward understanding a culture or a distinct social group through participant observation

Researcher…
– fully embraces the cultural norms
– describes and analyzes common themes
– reflexivity of impact on research and culture

61
Q

Correlational Design

A

Correlational design: researchers gather information on participants, and make no effort to alter experience.

Example: Is maternal warmth an important precursor to positive child adjustment?

No Causal Relations

Correlation coefficient indicates strength of association

62
Q

Experimental Design

A

the “Gold Standard”

Experimental design: allows inference of cause and effect because researcher assigned people to two or more “treatment conditions”

– Variable: a factor that can be manipulated by the researcher
– Independent variable: Causes change in another variable
– Dependent variable: Variable expected to be influenced by independent variable

Random Assignment: participants must have equal chances of being in treatment groups

63
Q

El-Sheikh, Cummings & Reiter

A

1996

RQ: How does adults’ angry interactions affect children’s adjustment?

H1: Angry encounters (independent variable) affect children’s emotional reactions (dependent variable).

Two groups:
– Unresolved anger
– Resolved anger

Results:
– Anger resolution can reduce children’s distress

64
Q

Longitudinal Design

A

A single group of participants are studied repeatedly over time

Strengths:
– Track performance over time
– Permit investigators to examine relationships between early and later events & behaviors

Limitations:
– Biased sampling
– Selective attrition
– Practice effects
– Cohort effects
65
Q

Cross-Sectional Design

A

All data collected at one time, often on several different groups

Major problem:
Impact of time or event not directly measured
– Example: Compare marital satisfaction of parents and non-parents
– Parents less satisfied
– See Twenge, Campbell, & Foster (2003)

66
Q

Cross-Sequential Designs

A

Examining individuals in several different age groups over time

Example: 
Alink et al. (2006), Child Development.
– Studied developmental course of physical aggression in 1-4-year-old children 
– Results from cross-sectional analyses
     52% 12-month-olds
     80% 24-month-olds
     78% 36-month-olds
Results from longitudinal analyses: bellcurve-ish

can possibly rule out cohort effects

67
Q

Ethics in Research with Children

A
Protection from harm
Informed consent/assent
Privacy
Knowledge of results
Beneficial treatment
  • *American Psychological Association
  • *Society for Research in Child Development
68
Q

Who monitors research

procedures at Ohio State?

A

Institution Review Board (IRB)
– Every institution that seeks federal funding for research on human subjects is required to have an IRB

OSU Human Participants Protection
– Office of Responsible Research Practices, http://orrp.osu.edu
– All research by OSU faculty and students must receive approval by the IRB
– Training on research ethics is required

69
Q

Avoid harm

A

What is harm?

Psychological Harms: undesired changes in thought processes and emotion (e.g., episodes of depression, confusion, feelings of stress, guilt, and loss of self-esteem)

Minimal risk: “the probability and magnitude of harm or discomfort … are not greater, in and of themselves, than those ordinarily encountered in daily life or during the performance of routine physical or psychological examinations or tests”

Department of Health & Human Services:
http://www.hhs.gov/ohrp/archive/irb/irb_chapter3.htm

70
Q

Informed consent

A

Can only be given by competent persons

Must be given voluntarily

Includes full information about the research
– The purpose, procedure, and risks/benefits of the study

Participants must understand what they’ve been told
– All questions (of the subject) are answered
– Participants voice understanding

Vulnerable populations:
– Children
        - Parental permission
        - Assent
– Individuals with diminished decision-making capacity

Research not involving informed consent:
Observation of naturally occurring behavior in public settings, provided that anonymity and unobtrusiveness are ensured

71

Q

Cohort Effects

A

The effects of being born at about the same time, exposed to the same events in society, and influenced by the same demographic trends and thus, having similar experiences that make the group unique from other groups.

Cohort effects are most likely to be a problem during a cross-sectional study as it is difficult to separate effects of developmental changes from cohort effects when examining age effects across a wide range of ages (Cozby).

Results based on one cohort may no apply to children developing at other times.

82
Q

Microgenetic design

A

a scientific method in which the same setting is studied repeatedly in order to observe change in detail.

In contrast to cross-sectional and longitudinal designs, which provide broad outlines of the process of change, microgenetic designs provide an in-depth analysis of the behavior of the system while it is changing.

Introduction to Bronfenbrenner’s Ecological Systems Theory

A

Urie Bronfenbrenner is a famous developmental psychologists known for his Ecological Systems theory.

The chronosystem is made up of the environmental events and transitions that occur throughout a child’s life, including any sociohistorical events. The chronosystem is 1 of 5 systems in Bronfenbrenner’s ecological systems theory.

In 1979, Urie Bronfenbrenner created his ecological systems theory to explain how their immediate and surrounding environment affects the way in which children grow and develop.
There are 5 different environmental systems that influence childhood development. If there is a change in any one of the 5 environmental systems, it can potentially cause a change in the others. The 5 systems are:

Microsystem
Mesosystem
Exosystem
Macrosystem
Chronosystem

A child lies in the middle of the image. Each circle that surrounds the child is a different layer or environmental system that affects the child’s growth & development.

The microsystem is where the immediate interactions of the child take place. The microsystem includes family and peers.

The mesosystem contains the interactions between microsystems. Having your friends (or your peer microsystem) attend a family gathering (your family microsystem) is an example of a mesosystem.

The exosystem contains the environmental settings in which the child is not actively involved but that nonetheless have a significant influence on the child. An example of an exosystem would be if the child’s father was laid off from work.

The macrosystem, which is the larger cultural context, includes the political beliefs of the child’s culture.

Bronfenbrenner’s Chronosystem
The 5th and final level of Bronfenbrenner’s ecological systems theory is known as the chronosystem. This system consists of all of the experiences that a person has had during his or her lifetime, including environmental events, major life transitions, and historical events.

Q

correlation coefficient

A

In statistics, the correlation coefficient is a measure of the linear correlation between two variables X and Y, giving a value between +1 and −1, where 1 is total positive correlation, 0 is no correlation, and −1 is total negative correlation. It is used as a measure of the degree of linear dependence between two variables.
