PYB203 STUDY GUIDE Flashcards
Domains of development
Physical –> the growth of the body and its organs, the functioning of the physiological systems, including the brain, physical signs of ageing, changes in motor abilities etc.
Cognitive –> changes and continuities in perception, language, learning, memory, problem solving and other mental processes
Psychosocial –> changes and continuities in personal and interpersonal aspects such as motives, emotion, personality traits, interpersonal skills, relationships and roles played in the family and in society
Nature and nurture
Nature –> heredity, maturation, genes, innate predispositions
Nurture –> environment, learning, experience, cultural influences
Freud’s psychodynamic theory of development
Postulates that people are driven by motives and emotional conflicts of which they are largely unaware of. People’s lives are shaped by their earliest experiences.
Psychodynamic approach: the importance of the unconscious
The structure of personality (Sigmund Freud) is based off of three facets:
ID: pleasure principle
EGO: reality principle
SUPEREGO: conscience
Freud’s stages of psychosexual development
Development occurs through a series of psychosexual stages. In each stage, the child focuses on a different area of their body and how they invest their sexual energy into relationships with people and things reflects what stage they are in.
Oral –> Birth – 1 year: the mouth is the focus of stimulation and interaction; feeding and weaning are central.
Anal –> 1-3 years: the anus is the focus of stimulation and interaction; elimination and toilet training are central.
Phallic –> 3-6 years: the genitals are the focus of stimulation; gender role and moral development are central
Latency –> 6-12 years: a period of suspended sexual activity; energies shift to physical and intellectual activities
Genital –> 12-adulthood: the genitals are the focus of stimulation with the onset of puberty; mature sexual relationships develop.
Erik Erikson’s psychosocial theory
Dialectical conflict is the basic mechanism of development. This theory places a large emphasis on social influences, such as peers, family, school etc.
Classical conditioning
Developed by Ivan Pavlov. A conditioned / unconditioned response is elicited by a conditioned / unconditioned stimulus. In infancy, this equates to reflex learning –> the touch of a nipple elicits a sucking reflex
Operant conditioning
Developed by B.F. Skinner. Reinforcement strengthens a response and punishment weakens a response. Both reinforcement and punishment can either be positive or negative.
Positive reinforcement –> increases behaviour by delivering a desired stimulus
Positive punishment –> decreases behaviour by delivering an adverse stimulus
Negative reinforcement –> increases behaviour by removing an adverse stimulus
Negative punishment –> decreases behaviour by removing a desired stimulus
Piaget’s cognitive theory
Postulates that children actively construct new understandings of the world based on their experiences.
Cognitive stage theory:
Sensorimotor –> birth-2 years: coordination of sensory and motor activity; achievement object permanence
Preoperational –> 2-7 years: use of language and symbolic representation; egocentric view of the world, make-believe play
Concrete operational –> 7-11 years: solution of concrete problems through logical operations; objects are organised into hierarchies and classes and subclasses; thinking is not yet abstract
Formal operational –> 11-adulthood; systematic solutions of actual and hypothetical problems using abstract symbols
Piaget’s concepts
Direct learning (schemes)
Assimilation –> new information fits into existing schemes
Accommodation –> changing schemes to incorporate new
information or ideas
Adaptation –> the tendency to adjust to the environment
Cognitive-developmental approach (Vygotsky)
This theory argues that cognitive abilities are socially guided and constructed.
Focuses on the cultural nature of human development and postulates that social interaction drives cognitive development
Bronfenbrenner’s ecological systems theory
Examination of a wider community and individual’s relationship with others - how this explains development.
- microsystem - Face-to-face interactions
- mesosystem - Connections between microsystems
- exosystem - Indirect influences
- macrosystem - General aspects of society
Infancy
a period of rapid growth and development in a range of areas:
- Physical
- Perceptual
- Cognitive
- Language
- Social and emotional
Infancy motor development
Newborn reflexes - reflexes are unlearned, involuntary responses to stimuli. Survival reflexes are adaptive (e.g., breathing, eye-blink, sucking). Primitive reflexes are less adaptive and typically disappear in early infancy
Infant motor development follows two trends:
1. Cephalocaudal (head to tail) - control of the head occurs first
2. Proximodistal (near to far) - control in the trunk before control in the arms or fingers.
Gross motor skills –> movement of large muscles of arms, legs, and torso
Fine motor skills –> movement of small muscles such as fingers, toes
Infant perception
How we know and understand what babies can see/perceive/know.
Habituation (infant perception)
The process of learning to be bored with a stimulus. After repeated presentation with the same visual stimulus, the infant becomes bored and looks away. If a different stimulus is presented and the infant regains interest, researchers conclude that the infant has discrimination between the two stimuli.
Preferential looking (infant perception)
Researchers present an infant with two stimuli at the same time and measure the length of time the infant spends looking at each. A preference for one over the other indicates that the infant discriminates between the two stimuli.
Evoked potentials (infant perception)
Researchers can assess how an infant’s brain responds to stimulation by measuring its electrical conductivity.
Infant vision
At birth, infants can have visual abilities, but lack acuity:
–> Can see more clearly about 20—15cm
Vision improves steadily during infancy
Infant cognition –> Piaget’s sensorimotor stage
Postulates that the world is understood through the senses and actions. The dominant cognitive structures are the behavioural schemes that develop through coordination of sensory information and motor responses.
There are 6 substages :
1. Reflexes (first month) –> reflexive reaction to internal and external stimulation
2. Primary circular reactions (1-4 months) –> infants repeat actions relating to their own bodies
3. Secondary circular reactions (4-8 months) –> repetitive actions involving something in the infant’s external environment
4. Coordination of secondary schemes (8-12 months) –> secondary actions are coordinated in order to achieve simple goals (i.e., pushing or grasping)
5. Tertiary circular reactions (12-18 months) –> experimentation; actions are repeated with variations
6. Beginning of thought: (18 months) –> symbolic thought permits mental representation, imitation, and recall
Infant cognition: the development of object permanence
Objective permanence develops during the sensorimotor period.
- From 4-8 months, “out of sight, out of mind”
- By 8-12 months, make the A-not-B error
- By 1 year, the A-not-B error is overcome, but continued
trouble with invisible displacement
- By 18 months, object permanence is mastered
Infant psychosocial development: attachment
Attachment is a strong and enduring emotional bond that develops between an infant and a caregiver during the infant’s first year of life. Characterised by reciprocal and shared desire to maintain physical and emotional closeness:
Psychoanalytic - I love you because you feed me
Learning - I love you because you are reinforcing
Cognitive - I love you because I know you
Ethological - I love you because I was born to love
4 phases of infant attachment development
1) Birth – 2 months –> indiscriminate sociability
2) 2-7 months –> attachments in the making, increasing preference for familiar cares
3) 7-24 months –> specific, clear-cut attachments, separation, and stranger anxiety
4) 24 months + –> goal-coordination partnerships
Separation anxiety
Once attached to a parent, a baby often becomes wary or fretful when separated from that parent. Separation anxiety normally appears when infants are forming their first genuine attachments, peaks between 14 and 18 months, and gradually becomes less frequent and less intense
Stranger anxiety
Once attached to a parent, a baby often experiences a wary or fretful reaction to the approach of an unfamiliar person. Anxious reactions to strangers become common between 8 and 10 months, continue through the first year, and gradually decline in intensity over the second year
the strange situation
The strange situation is a procedure devised by Mary Ainsworth in the 1970s to observe attachment in children, that is relationships between a caregiver and child. It applies to children between the age of nine and 30 months. Broadly speaking, the attachment styles were secure and insecure.
secure attachment
Secure attachment is classified by children who show some distress when their caregiver leaves but are able to compose themselves quickly when the caregiver returns. Children with secure attachment feel protected by their caregivers, and they know that they can depend on them to return
ambivalent attachment
As the labels suggest, people with this attachment style are often anxious and uncertain, lacking in self-esteem. They crave emotional intimacy but worry that others don’t want to be with them.
disorganised attachment
A disorganized / fearful-avoidant attachment style develops when the child’s caregivers – the only source of safety – become a source of fear. In adulthood, people with this attachment style are extremely inconsistent in their behavior and have a hard time trusting others.
