Developmental Psychology Flashcards
Down’s Syndrome
Mental retardation stemming from an extra 21st chromosome
Turner’s Syndrome
Found in females with only 1 X chromosome
Stages of prenatal development
Zygote: Sperm fertilizes the egg and forms zygote.
Germinal stage: Fertilized egg goes down the fallopian tube and attaches to uterine wall.
Embryonic stage: 8 weeks after germinal period. Size increases by 20,000 times.
Fetal stage: Begins 2 months post conception with measurable electrical activity in the brain.
Neonatal reflexes
A behaviour that occurs automatically in response to a stimuli
Blinking - closing eyes in response to light
Sucking - sucks when object paced in mouth
Rooting - turns head in direction of stimuli when applied to the cheek
Moro - abrupt movement of the head causing arms to splay out, fingers fan out and then arms come back to the body & baby hugs itself
Babinski - toes automatically spread when soles are stimulated
Grasping - automatically closing fingers when object is placed in hand
Locomotor development in infants
Birth: fetal posture 1 month: lift head 2 months: lift chest 3 months: reach and miss 4 months: sit with support 5 months: sit on lap, grasp objects 6 months: sit in high chair 6.5 months: sit alone 8 months: stand with help, stand holding furniture, pull to stand 10 months: crawl 11 months: crawl up stairs, walk when led, stand alone 12 months: walk alone
Visual cliff experiment
Study by Gibson to test depth experiment on babies
2 month old show change in heart rate
6-7 month don’t go across
Assimilation & accommodation according to Piaget
Assimilation is the process of interpreting new information in terms of existing schemata.
Accommodation occurs when new information doesn’t really fit into existing schemata; it is the process of modifying existing schemata to adapt to this new information.
Stages of Piaget’s theory
Sensorimotor stage
Pre-operational stage
Concrete operational stage
Formal operational stage
Features of sensorimotor stage
0-2 yrs
Learns relationship between actions and external world; grasp idea of cause and effect
Primary and secondary circular reactions
Object permanence - object continue to exist even when not in field of vision
Features of pre-operational stage
2-7 yrs
Egocentrism - inability to understand that others perceive the world differently than they do
Symbolic play - decentration (others are recipient of playful action), decontextualization (objects can substitute others), integration (combining play actions into complex sequences)
Develop theory of mind - Understanding that human behavior is guided by mental representations of the world.
Lack conservation
Centration - children pay attention on one part of a stimuli to the
exclusion of all others
Lack seriation, reversibility and relational terms
Animism - Children’s belief that inanimate objects have
“lifelike” qualities
Features of concrete operational stage
7-12 yrs
Understand seriation and relational terms
Reversibility - many physical reactions can be undone by reversing the original action
Emergence of logical thought
Features of formal operational stage
Adolescence
Logical thinking
Abstract thinking
Hypothetico-deductive reasoning (formulating general theory and deducing specific hypotheses from it)
Vygotsky’s sociocultural theory
The theory that intelligence develops largely as a result of internalization, by children absorbing what they observe in the environment and making it a part of themselves.
Development occurs in part through a zone of proximal development, which distinguishes what children can do on their own (zone of actual development) from what they can do with the assistance of others (zone of potential development).
Stressed that culture and social factors play a role in cognitive development.
Reciprocal teaching, scaffolding, guided participation, play
Scaffolding
Mental structures child can use when learning new skills. Adjusting levels of support to meet child’s needs.
Eg: visual aid, model & demonstrating, practice time, explaining in diff ways
Kolhberg’s stages of moral development
PRECONVENTIONAL
1 - Punishment & obedience
2 - Naive hedonistic orientation
CONVENTIONAL
3 - Good boy/girl orientation
4 - Maintaining social order
POSTCONVENTIONAL
5 - Legalistic orientation
6 - Universal ethical principle orientation
Bowlby attachment style
Attachment: A deep and enduring emotional bond between two people in which each seeks closeness and feels more secure when in the presence of the attachment figure.
Phase 1: Infant reacts identically to every adult & smiling face
Phase 2 (3 months): Infant discriminates familiar & unfamiliar faces
Phase 3 (6 months): Specific attachment - Infant seeks out and responds to mother; emergence of separation anxiety
Phase 4 (9-12 months): Stranger anxiety - response to arrival of a stranger
Phase 5 (2 yrs old): Distress level when separated from carer, degree of comfort needed on return
Phase 6 (3 yrs old): Child can separate from mother without prolonged distress
Harry Harlow attachment theory
To study the early relationship between caregiver and infants
Studied Rhesus monkeys; took them away from mother 6-12 hours after birth.
Kept in cages with 2 types of surrogate mothers - one wire cylinder with feeding nipple attached & another cloth covered wooden cylinder with no feeding option.
Monkeys preferred the cloth mother; contact comfort.
Mary Ainsworth attachment style
Strange situation procedure to study quality of parent-child relationship
Child kept in unfamiliar room with mother and plays with toys. After 3 min, stranger enters room and talking to mother and child. Then mother leaves and stranger interacts with infant. Then mother returns and stranger leaves. Then infant is left alone. Then stranger returns and interacts with infant. Then mother returns and stranger leaves.
3 attachment styles
- Insecure avoidant
- Secure attachment
- Insecure resistant
Sequential cohort studies
Combination of longitudinal and cross-sectional study; diff groups of diff ages studied across several years
Private speech according to Vyogtsky
Language as a means of thinking of mental activities and behaviour; way of guiding oneself
Private changes to inner speech - whispers, silent lip movement
Increases when tasks are challenging, confused on how to process, when mistakes are made
Inverted V shape
Private speech in children with learning difficulties - higher rate; maybe compensation for impairments in cognitive functioning
Zone of proximal development
Range of tasks that are too difficult to accomplish by themselves; accomplished with assistance from adults or more skilled peers
Parents to keep task manageable and give prompts to make task manageable
Social interaction is key
