Development psychology → Area of psychology that is concerned with changes in physical and psychological functioningÂ
How and why people change over timeÂ
Occurs from conception across entire life spanÂ
Development is the more or less predictable changes in behaviour associated with ageÂ
Stage | Age period |
Prenatal | Conception to birth |
Infancy | Birth at full ters to about 18 months |
Early childhood | About 18 months to about 6 years |
Middle childhood | About 6 years to about 11 years |
Adolescence | About 11 years to about 20 years |
Early adulthood | About 20 years to about 40 years |
Middle adulthood | About 40 years to about 65 years |
Late adulthood | About 65 years and older |
Stage theories of developmentÂ
Stages → series of abrupt changes from one period to another (discontinuity)Â
All children must pass through in same order what are some North American milestonesÂ
Many advocate that changes unfold over time (continuous change or continuity)Â
Qualitative than quantitative (such as child mastering physical properties of object)Â
Studying developmentÂ
Often conceptualize the lifespan as either gains or losses (debits and credits)Â
How do we study change over time?Â
Normative investigationsÂ
Describe characteristics of a specific age or developmental stage (average level norms) height, weight, reading, writingÂ
Chronological and development age what is normal/make comparisonsÂ
E.g. Comparing a 2 year old to other 2 year olds in the same country you live inÂ
Doctor comparing your height to different percentiles and seeing where your average isÂ
EQAO is an example of thisÂ
Problem with this is that people come from different countries such as people who come guyana aren’t looked at from that perspectiveÂ
Who assesses variations in development? → these people use normative investigationsÂ
PhysiciansÂ
NursesÂ
Day care workersÂ
Speech language pathologistsÂ
Occupational and physiotherapistsÂ
TeachersÂ
PsychologistsÂ
A sequential design incorporates both longitudinal and cross sectional designsÂ
Longitudinal designÂ
Repeated observation and testing of the same people over timeÂ
Is there benefit? Short term and long termÂ
Up series by Michael Apted followed the lives of fourteen British children since 1964
Able to study longer term individual differencesÂ
Age related changes cannot be confused with variations in different societal circumstances (assessment of Gen Z, Gen Y and Gen X)Â
Costly, time consuming, where is the data?, only one group
Cross sectional designÂ
Groups of participants of different chronological ages are observed and compared at the same time (e.g., a census)Â
More groups can be studiedÂ
Political and societal variables may confound the resultsÂ
The sequential design is actually a combination of both a cross sectional design and a longitudinal design. Using a sequential design, we study several cohorts, or age groups, over a long period of timeÂ
Jean Piaget believed that representations of reality change at different stages needed for adaptationÂ
wasn’t interested in the amount of knowledgeÂ
Through the studies PIaget carefully watched children and listened to them reason as they tried to solve problemsÂ
He proposed that children’s thinking changes qualitatively with age it is not that children are simply less practiced, it is that the way they think is different from the way adults thinkÂ
To achieve the understanding of the world the brain builds schemas which are organized patterns of thought and action (internal framework) which guides our interaction with the worldÂ
Ex. infants are born with a sucking reflex which provides a primary framework, a schema for interacting with physical objects.Â
Mental structures that enable individuals to interpret the world called schemesÂ
Assimilation → modifies new environmental information to fit into what is already known (interpret new input according to existing schemes)Â
Ex. peter’s daughter loving a red rubber ball and would laugh however, when she started eating real foods she loved apples, she would throw her red ball lose track and get an apple and do the same but it didn’t bounce or sound the same but they looked the same → she did accommodation and learned the difference between the twoÂ
Ex. ball vs apple vs pumpkinÂ
Ex. when a young infant encounters a new object, a small plastic toy, a blanket, or a doll they will try to suck it. The infant tries to “fit this new experience into a schema that they already have: objects are suckableÂ
Ex. a child who sees a horse for the first time may exclaim “big doggie.” After all, the horse has four legs, and a tail just like a the family pet, so the child tries to make sense of this new experience by applying the familiar schema: “doggie”Â
Accommodation → restructure or modifies the child’s existing schemes so that new information is accounted forÂ
Ex. when an infant tries to suck different objects, they will eventually encounter ones which are too big to go into their mouth or taste badÂ
Ex. the child who calls a horse a “big doggie” eventually will realize that this “big doggie” doesn’t bark, sit, fetch, or otherwise behave like a dogÂ
Balance and imbalance → ex. Change in belief systemÂ
Ex. the infants “suckability” schema will become more complex, some objects are suckable, some are notÂ
Ex. the child’s “doggie” schema also will change, and they will begin to develop new schemas for “horsey,” “kitty” and so son
Assimilation and accommodation work in togetherÂ
Stages of cognitive developmentÂ
Things to keep in mind:Â
Cognitive development within each stage seems to proceed inconsistently. A child could perform at the preoperational level on some tasks, yet solve other tasks at concrete operational levelÂ
Culture influences cognitive developmentÂ
Piaget looked at cognitive development with a scientific logical thinking and western perspectiveÂ
Many cognitive skills and concepts at an earlier age than Piaget thoughtÂ
Sensorimotor stage (0-2)Â
Senses and motion without the use of symbolsÂ
Mobility allows for knowledge acquisitionÂ
Object permanence understanding that objects exist independent from awareness (around age 2)Â
At age 2 the brain is 80% of adult weighÂ
Preoperational stage (2-7)Â
Use of symbols, language matures, memory develops, imagination develops → most learning happens hereÂ
Big ones for us are language and numbersÂ
Putting your hand up in front of toddler that means stop, putting your hand up to ask a question or answer one, school bell (school started/end, recess, lunch)Â
Non reversible thinkingÂ
Egocentrism → inability to take other’s perspectivesÂ
This isn’t selfishness but rather that children at this stage believe that other people perceive things in the same way they doÂ
Ex. hide and seek a preoperational child showing egocentrism will believe that if they can’t see you, then you can’t see them, and so they may in a way that only obscures their view of youÂ
Centration → tendency for attention to be captured by perceptually striking features of objectsÂ
Rapid language development helps children label objects and represent simple concepts, such as that two objects can be “the same” or “different”Â
Children can think about the pastÂ
Ex. Yesterday or the future “tomorrow,” “soon”Â
Concrete operations stage (7-11)Â
Conservation physical properties of objects don’t change even though appearance might (reversibility)Â
Intelligence is demonstrated through logical systematic manipulation of symbols to concrete objectsÂ
During this stage they have difficulty with hypothetical problems or problems requiring abstract reasoning they often show rigid types of thinkingÂ
Reversibility - 1 + 1 = 2 & 2 minus 1 = 1Â
Formal operations stage (11 - adult)Â
Development of abstract and hypothetical thinkingÂ
Consider series of alternatives and logical thinkingÂ
Return to egocentric thinkingÂ
Contemporary cognitive viewsÂ
Renee Baillargeon and infant cognitionÂ
Demonstrated that some aspects of Piaget’s stages don’t occur in orderÂ
Violation of expectation experiments - rudimentary object permanence at a younger age (4-5 months)Â
Theory of mindÂ
This refers to a person’s beliefs about the mind and the ability to understand other people’s mental statesÂ
We have theories about the contents of other people’s minds we use these assumptions to explain and predict our own and other people’s behaviourÂ
Lying and deception reflect this theory, evidence indicates that those who understand false beliefs are more likely to lie, starting as early as three years of ageÂ
They will understand the difference between a mistake and a lie. For both a mistake and a lie, what I say is wrong. The difference is that in one case, the lie, I recognize that you do n’t know what is going on inside my mind and so I can deceive youÂ
Frameworks for initial understanding called foundational theories (accumulation of experiences)Â
Lev Vygotsky and internalizationÂ
Process of absorbing knowledge from the social and cultural context that has a major impact on how cognition unfolds over timeÂ
Zone of proximal development → little apprenticesÂ
This is the difference between what a child can do independently and what a child can do with assistance from adults or more advanced peersÂ
It emphasizes that people can help to “move” a child’s cognitive development forward within limits (the “zone”) dictated by the child’s biological maturationÂ
Ex. parents who assist a child on a scientific tasks may push the child’s understanding further along by using age appropriate but cognitively demanding speech (introducing scientific concepts) rather than simpler speechÂ
Social development → how individuals social interactions and expectations change over timeÂ
Conclusions based on the “average” life course, but development not independent from cultural and environmental aspects
Erikson’s psychosocial stages represents 8 conflicts or crises that every individual must face through the lifespanÂ
Four crises occur infancy and childhoodÂ
Basic trust vs basic mistrust → depending on how adequately our needs are met, and how much love and attention we receive during the first year of life, we develop a basic trust or basic mistrust of the worldÂ
Autonomy vs shame and doubt → during the next two years, children become ready to exercise their individuality. If parents unduly restrict children or make harsh demands during toilet training, children develop shame and doubt about their abilities and later lack the courage to be independentÂ
Initiative vs guilt → from age three through five, children display great curiosity about the world. If they are allowed freedom to explore and receive answers to their questions, they develop a sense of initiative. If they are held back or punished, they develop guilt about their desires and suppress their curiosityÂ
Industry vs inferiority → from age six until puberty, the child’s life expands into school and peer activities. Children who experience pride and encouragement in mastering taks develop an industry striving to achieve. Repeated failure and lack of praise for trying leads to a sense of inferiorityÂ
Erikson’s Psychological StagesÂ
First year → Basic trust vs. basic mistrustÂ
1 - 2 → Autonomy vs. shame and doubtÂ
3 - 5 → Initiative vs. guiltÂ
6 - 12 → Industry vs. inferiorityÂ
12 - 20 → identity vs. role confusionÂ
20 - 40 → Intimacy vs. isolation
40 - 65 → Generativity vs. stagnationÂ
65+ → Integrity vs. despair Â
Socialization → lifelong process through which an individual’s behaviour patterns, values, standards, skills, attitudes, and motives are shaped to conform to those regarded as desirable in a particular societyÂ
Process involves many individual and social factors but family is most important in basic responsiveness to othersÂ
Help us understand societal normsÂ
Personality and social developmentÂ
Emotion
18 months develop sense of selfÂ
Display variety of basic emotionsÂ
Envy, embarrassment, empathy can begin to emergeÂ
Age 2 learn rules and performance standardsÂ
Display guiltÂ
Emotion regulation becomes more diverseÂ
Emotional competence increasesÂ
Socialization and heredity contribute to emotional developmentÂ
TemperamentÂ
Biologically based levels of emotional and behavioural response to the environmentÂ
Ex. some infants are calm and happy; others are irritable and fussy, some are outgoing and active; others are shy and inactiveÂ
We are not all the same in regards to our social responsesÂ
Inhibited (shy,withdrawn) and uninhibited babies (sociable, outgoing) falls on a continuumÂ
Sets the stage for later aspects of development and can have interactive effects (social anxiety, antisocial) but not alwaysÂ
Attachment → intense social emotional relationship with mother, father, or regular caregiverÂ
Some species experience imprinting of the first moving object they see (Konrad Lorenz)Â
Ex. the strongest imprinting takes place within one day after hatching, and by two and a half days the capacity to imprint is lostÂ
John BowlbyÂ
Humans biologically predisposed to form attachments (agreed with maslow) but become more selective in their attachment choicesÂ
Indiscriminate attachment → newbornsÂ
Newborns cry, vocalize, and smile, and they emit these behaviours toward everyone. In turn, these behaviours evoke caregiving from adultsÂ
Discriminant attachment → 3 monthsÂ
Around three months of age, infants direct their attachment behaviours more toward familiar caregivers than toward strangersÂ
Specific attachment → 7 monthsÂ
By seven or eight months of age, infants develop their first meaningful attachment to specific caregivers. The caregivers become a “secure base” from which the infant can crawl about and explore the environmentÂ
Contact and social bondingÂ
Freud’s cupboard theory → is bonding only for the purpose of being fed?Â
Harry Harlow and contact comfortÂ
Monkey studies → he separated infant rhesus monkeys from their biological mothers shortly after birth. Each infant was raised in a cage with two artificial, “surrogate” mothers. One was a care wire cylinder with a feeding bottle attached to its “chest.” The other was a wire cylinder covered with soft terry cloth, without a feed bottle. Faced with this choice, the infant monkeys became attached to the cloth mother. When they were in frightening situations, the infants ran to the terry cloth figure and clung tightly.Â
Stephen Suomi and cross fosteringÂ
Attentive adoptive monkey mothersÂ
Human deprivation and lack of consistency linked to physical and social deficitsÂ
Mary ainsworth and the Strange Situation Test → stranger and separation anxietyÂ
Studies of attachment by Mary Ainsworth involved a mother leaving her infant with a stranger. Ainswoeth believed that the infants attachment style could be categorized according to their behavioural responses to the mother leaving and returningÂ
Three main types of attachment styleÂ
Secure (70%)Â
In the mother’s presence infants explore the playroom and react positively to strangers, they are distressed when she leaves and happily greet her when she returns
They are better adjusted socially during childhoodÂ
Insecure - avoidant (20%)Â
Infants show few signs of attachment and seldom cry when the mother leaves and don’t seek contact when she retuns
Insecure ambivalent/resistant (10%)Â
infants are fearful when the mother is present, demand her attention, and are highly distressed when she leaves, they are not soothed when she returns and may angrily resist her attempts as constantÂ
Disorganized attachmentÂ
Infants which show disorganized attachment may appear disoriented and confused, or they may show contradictory behaviours, such as simultaneously trying to get close to the mother and freezing or striking out when the mother tries to comfort themÂ
Highly predictive of child’s later behaviour and interactions with othersÂ
Parenting style and practicesÂ
Parenting styles range on dimensions of demandingness and responsivenessÂ
Parents have different socialization goals for their children which determine parentingÂ
The child may influence the goalsÂ
Authoritative parents → controlling but warm, they establish clear rules, consistently enforce them, and reward children’s compliance with warmth and affection. They communicate high expectations, caring, and support this is associate with the most positive childhood outcomesÂ
These children have higher self esteem, high achievers in school and have fewer conduct problemsÂ
Authoritarian parents → exert control over their children, but do so within a cold, unresponsive, or rejecting relationship
These children have lower self esteem, be less popular with peers and perform more poorly in school than children with authoritative parentsÂ
Indulgent parents → have warm and caring relationships with their children, but do not provide the guidance and discipline that helps children learn responsibility and concern for othersÂ
These children tend to be more immature and self centredÂ
Neglectful parents → provide neither warmth nor rules and guidanceÂ
These children are most likely to be insecurely attached, have low achievement motivation and disturbed relationships with peers and adults at school and be impulsive and aggressive
Neglectful parenting is associated with the most negative developmental outcomes Â
Moral developmentÂ
Morality → a system of beliefs, values, and underlying judgements about the rightness or wrongness of human actsÂ
Lawrence Kohlberg and theory of moral developmentÂ
Studied moral reasoning in seven stagesÂ
Shaped by Piaget changing importance of consequences of acts and intentionsÂ
Moral dilemmas used to evaluate reasons for moral decisions: privacy facebook? Should apple unlock the phone?Â
Children do not see morality as adults do they are more interested in what others think?Â
Level of Moral Reasoning | Basis for Judging What Is Moral |
Level 1: Preconventional | Actual or anticipated punishment and rewards, rather than internalized values |
Stage 1: Punishment/obedience orientation | Obeying rules and avoiding punishment |
Stage 2: Instrumental/hedonistic orientation | Self interest and gaining rewards |
Level 2: Conventional | Conformity to the expectations of social groups; person adopts other people’s values |
Stage 3: Good child orientation | Gaining approval and maintaining good relations with others |
Stage 4: Law and order orientation | Doing one’s duty, showing respect for authority and maintaining social order |
Level 3: Postconventional | Moral principles that are well thought out and part of one’s belief and value system |
Stage 5: Social contract orientation | General principles agreed upon by society that foster community welfare and individual rights: recognition that society can decide to modify laws that lose their social utility |
Stage 6: Universal ethical principles | Abstract ethical principles based on justice and equality: following one’s conscience |
Four key principles in Kohlberg’s model
An individual can be at only one stage at a given timeÂ
Everyone goes through the stages in a fixed orderÂ
Each stage is more comprehensive and complex than the precedingÂ
The same stages occur in every cultureÂ
