Newborn
• Have ability at birth to see, hear, smell and respond to environment
• Born with some reflexes– Grasping reflexes– Rooting reflex
• Response in turning toward the source of touching anywhere around his/her mouth
Physical development
• Maturation
• Internally programmed growth of a child
• Unless a child underfed, restricted in movements, deprived of human contacts and things to look at she will develop according to schedule
• If not at maturational readiness a child will no master the skill
Perceptual development
• Look at faces and patterned materials most and benefit from parent touch
• Visual Cliff
• Young infants were unafraid but infants 6 months and up found changes in hear rate= danger
Language Development
• Nature vs. nurture• Steps
– Make signs-hand or mouth – Learn meaning– Learn grammar
• 1 year-babbling, • late first year-sounds more like their
language– They imitate and are praised
Language Continued
• 2 years old– Sounds as symbols
• End of 2nd year2 word phrases– Telegraphic speech
• Words are left out but the meaning is usally clear “where my apple?”
• **Between 18 months and 5 years they add 5-10 words a day!
Cognitive and Emotional development
• Cognitive Development• Hide and seek with a 4 year old vs. 7 year• Intelligence develops gradually as child grows• Schemas
– Mental representations of the world
• Assimilation– Try to use existing schemas in new situation
• Accommodation– We change our schema to fit the new object
Cognitive Development Cont
• Object Permanence– Object exists even when they cannot
see/touch it– Hiding a toy=cease to exist
• 7-12 will find under blanket but not your back
• 12-18 will search last place she saw
Cognitive Development
• Representational Thought– Ability for a child to picture something in their
mind– Witness a tantrum and next day do it
Principal of Conservation
• Conservation– 5-7quantitiy does not change when its
appearance changes– Water in a jar– Egocentric
• Inability to understand another persons perceptive
Piaget’s Stages of Cognitive Development
• Sensorimotor Stage– Schemas that involve body and sensations
• Preoperational stages– Mental images or symbols to understand
• Concrete operation– Use logical schemas but understanding still
limited to concrete objects
• Formal operational stage– Person is able to solve abstract problems
Emotional Development
• Attachment
• Imprinting– Inherited tendencies or responses that are
displayed by newborn animals when they encounter a new stimuli
– Geese
• Critical period– Best time in development to learn a skill
• Harlow monkey research– Wire monkey vs. cloth monkey
Parent child attachment
• 6 months – 3 years
• Strong attachment
