Longitudinal research design: research used to test the same individuals over time 7. Bandura's social learning theory:: "behavior is learned from the environment though the process of observational learning." children observe the people around them behaving in various ways. parents, teachers, friends, role models provide masculine and feminine behavior to observe and imitate 8. 1. sensorimotor 2. pre-operational 3. concrete operational 4. formal operations: the 4 stages of Piaget's Theory of Cognitive Development 9. the environment -everything on the inside changes to accommodate whats on the outside: The Environmental Press Model asserts that adaptation depends on what? 10. 23 chromosomes: If you were looking through a microscope at a normal sperm cell, how many chromosome should you see? 11. male-XY female-XX: Which parent contributes the "X" and which the "Y" chromosome? 12. condition where a person has 47 chromosomes instead of 46, with 3 rather than 2 chromosomes at the 21st position, which causes them to have a distinct appearance: what is Down Syndrome? 13. malnutrition= when a person does not consume enough food to sustain normal growth -stunting: failure of children to grow to a normal height for their age -wasting: children are severely under weight for their height/age: Malnutrition: how may children suffer from malnutrition? 14. big head, big eyes, big belly, long fingers less energy, reduced curiosity, won't learn as well, prone to disease: What physical symptoms do we see in malnourished children? 15. infancy (due to rapid growth rate): When is malnutrition most damaging? 16. cell body: soma- contains necessary material to keep alive 17. neurotransmitters: chemicals that are released from terminal buttons 18. dendrites: (D)etect / receive info from axons 19. axon: (A)announce / transmits impulses outward and sends impulse out to dendrite 20. terminal buttons: releases chemicals that transmit info from one neuron to another 21. perception: process where the brain receives, selects, modifies, and organizes incoming nerve impulses 22. sensation: physical stimulation of sense organs -the response of a sensory system (eyes, ears, tongue, skin, nose) when it detects a stimulus 23. Attention: The key component to sensory development is what? 24. -taste all 5 primary tastes except salty and sweet -smell: most advanced sense that newborns have -vision: cant see very far, but can see objects/colors -hearing: hear fairly well, but not perfect -touch: very developed/ sensitive to touch: How well developed is a newborn's sense of smell; taste; vision; hearing; sensations to touch? 25. visual cliff studies, as young as 6 weeks babies react with emotional indicators to difference in depth -at 7 months they react with more fear than interest: Depth perception in infants - how was it studied / what age child was studied / and what did the studies show? 26. integration= linking individual motions into a coherent, coordinated whole (walking, eating with a fork, buttoning a shirt) differentiation= distinguishing and mastering certain individual motions or skills (grasping fork, balance): What is "integration" and "differentiation" ? 27. gross motor skills- actions that use many parts of the body, producing large movements -sitting unsupported -standing holding on to something -crawling -walking fine motor skills- small body movements -grasping a rattle when placed in hand -reaching to hold object -thumb and finger grasp -stacking 2 blocks: Gross motor skills and fine motor skills - what are they? Give examples. 28. Cephalocaudal pattern - development from the head in a downward direction Proximodistal pattern - development from the center or core of the body in an outward direction: What do the terms cephalocaudal and proximodistal mean in regards to physical development? 29. inhibition: orienting responses and the ability to control internal and external distracting stimuli 30. Motherese: talking to an infant slowly and exaggerating changes in pitch and volume -sentences are short with clear pronunciation, distinct pauses, repetition of new words, and gestures to support verbal meaning 31. joint attention: shared focus on an object by 2 people by means of eye-gazing, finger-pointing or other vocal or non-vocal indication --parents labeling objects/ children relying on adults' behavior to interpret the label's meaning 32. telegraphic speech: the earliest sentences created by most children, which sounds a bit like telegrams because they include key nouns and verbs but generally omit all other words and grammatical inflections 33. Holophrase: a combination of a gesture and a single word that conveys more meaning than just the word alone 34. assimilation: when new experiences fit into existing schemes 35. equilibrium: occurs when there are a balance between assimilation and accommodation 36. accomodation: when schemes have to be modified as a consequence of new experiences 37. disequilibrium: existing schemes are inadequate structures for the assimilation or accommodation of new information 38. equilibration: follows disequilibrium when inadequate schemas are replaced with more advanced and mature schemas 39. Dynamic Systems Theory: motor development involves many distinct skills that are organized and reorganized over time to meet specific needs
