7748967150Piaget's Developmental Stagessensorimotor stage is the most complex period of time0
7748982372Piaget focuses on-the child -the environment1
7748982373schemesspecific psychological structures- organized ways of making sense of experience -changes with age --adaptation and organization account for changes in schemes2
7748988736Adaptationbuilding schemes through direct interaction with the environment consist of: -assimilation -accommodation3
7748994862assimilationuse current schemes to interpret the world4
7748997523accommodationcreate new schemes or adjust old ones after noticing that our current ways of thinking do not capture the environment completely5
7884734051equilibriumwhen children are not changing much they assimilate more than they accommodate6
7884737951disequilibriumduring times of rapid change children accommodate more than assimilate7
7749003074organizationa process that occurs internally, apart from direct contact with the environment. -once kids form new schemes they rearrange them, linking them with other schemes8
7749141720circular reactionprovides a special means of adapting their first schemes. It involves stumbling onto a new experience caused by the baby's own motor activity. The reaction is circular because as the infant tries to repeat the event again and again a sensorimotor response that originally occurred by chance strengthens into a new scheme. ex. caitlyn accidentally made a smacking sound on her lips after breastfeeding. She tried to repeat it until she became a expert at it9
7885003862sensorimotor stage0-2 years learning through interaction with the environment uses senses to interact with environment -six substages 1. reflexes 2. primary circular 3.secondary circular 4. coordinate secondary circular 5. tertiary 6.mental combinations10
78850921571. reflexes (birth-1 month)gain control over reflexes11
78851481022. primary circular ( 1-4months)repeat pleasurable chance behaviors over own body ex. thumb sucking12
78851652443. secondary circular (4-8months)repeat interesting actions in the surrounding world; imitation of familiar behaviors ex. squeeze rubber duck and quacks so they do it again and again13
78851956744. coordination of secondary circular (8-12)intentional or goal-oriented behavior- coordinating schemes deliberately to solve simple problems14
7885352306object permanencethe understanding that objects continue to exist when they are out of sight.15
7885549148A-not-B search errorif they reach several times for an object at a first hiding place (A) then see it moved to a second (B) they still search for it in the first hiding place (A)16
7885623766Tertiary (12-18mos)exploration of property of objects by acting on them in different ways; imitation of novel behaviors; ability to search in several locations for a hidden object (A-not-B search)17
78860307336. Mental representation (18-2 years)symbolic and thought; insight; make believe play, ability to find object that has been moved out of sight uses images and concepts18
7886142798violation-of-expectation methodresearches may habituate babies to a physical event to familiarize them with a situation in which their knowledge will be tested. Or they may show babies an expected event (one that is consistent with reality) and an unexpected event. Heightened attention the the unexpected event suggests that the infant is surprised by a deviation from physical reality and therefore is aware of that aspect of the physical world19
7886249725displaced referencerealization that words can be used to cue mental images of things not physically present -emerges around first birthday20
7886417566video-deficit effectpoorer performance after a video than a live demonstration declines after 2.5 years21
7886450955core knowledge perspectivebabies are born with a set of innate knowledge systems, or core domains of thought. -each of these prewired understandings permits a ready grasp of new, related information and therefore supports early, rapid development22
7886657815information-processing researches assume...assume we hold information in three parts of the mental system: -sensory register -short-term memory -long-term memory23
7886677691sensory registersights and sounds are represented directly and stored briefly ex. looking around you and closing your eyes an seeing that image24
7886691880short-term memory storeretain attended-to information briefly so we can actively "work" on it to reach our goals -working memory25
7886713902long-term memory storestores information permanently26
7886752409central executiveconscious part of the mind coordinates incoming formation with the information system controls attention selects, applies and monitors strategies27
7886801734automatic processesso well-learned that they require no space in working memory, and therefore, permit us to focus on other information while performing them. ex. typing on a computer28
7886826415executive functionthe diverse cognitive operations and strategies that enable us to achieve our goals in cognitively challenging situations ex. controlling attention, suppressing impulses, self-control29
7886913503recognitionnoticing when a stimulus is identical or similar to one previously experienced *simplest form of memory*30
7886921646recallinvolves remembering something to present -more challenging -improves with age31
7886982347infantile amnesianot being able to retrieve events that happen before age 332
7886986579autobiographical memoryability to recall many personally meaningful one time events from both the recent and the distant past: the day a sibling was born or a move to a new house33
7887044847Vygotsky's sociocultural theoryemphasizes that children live in rich social and cultural contexts that affect the way their cognitive world is structured. -children think in ways that have meaning in their culture34
7887058736zone of proximal developmenta range of tasks that the child cannot yet handle alone but can do with the help of more skilled partners35
7887281338Bayley Scales of infant and Toddler Developmentsuitable for children 1months-3.5 years 1. Cognitive Scale: attention to familiar and unfamiliar objects and pretend play 2. Language Scale 3. Motor Scale: fine motor skills such as grasping36
7887315408IQ Testindicates the extent to which the raw score deviates from the typical performance of same-age indiviuals37
7887351703normal distributionmost scores cluster around the mean with progressively fewer falling toward the extremes38
7887368643developmental quotients (DQs)because most infant test scores do not tap the same dimensions of intelligence measured at older ages they are labeled this39
7887442057Home observation for measurement of the environment (HOME)a checklist for gathering information about the quality of children's home lives through observation and parental interview40
7887637702languagea system of symbols and rules that allows us to communicate41
7887649597language acquisition device (LAD)an innate system that contains universal grammar -enables children, no matter what language they hear, to understand speak in a rule-oriented fashion as soon as they pick up enough words42
7887689288Broca's arealocated in the left frontal lobe supports grammatical processing and language production43
7887699759Wernicke's arealocated in left temporal lobe plays a role in comprehending and meaning44
7887781441interactionist perspective on languageemphasize interactions between inner capacities and environmental influences one type emphasizes information processing theory another type emphasizes social interaction45
7887870564cooingvowel like noises46
7887875622babblinginfant repeat consonant-vowel combinations, often in long strings such as babbabab or nananana47
7888066203joint attentionchild attends to the same object or event as caregiver -contributes greatly to early language development ex. parent pointing at something and baby telling what it is or repeating it48
7888083038underextensionwhen young children first learn words they sometimes apply them too narrowly ex. bear only meaning a bear49
7888089318overextensionapplying a word to a wider collection of objects and events than is appropriate ex. saying car for busses, trucks, an fire engines50
7888114108girls show faster language learning processes than boystrue51
7888125683telegraphic speechoccurs in two words phase -two word utterances that focus on high-cogent words, omitting smaller, less important ones52
7888139497production languagethe words and word combinations children use53
7888142836comprehension languagethe language they understand -develops ahead of production54

7888174794expressive styleproduce more social formulas and pronouns than referential style ex. "thank you" "done" "I want it"56
7888253591infant-directed speech (IDS)a form of communication made up of short sentences with high-pitched, exaggerated expression, clear pronunciation, distinct pauses between speech segments, clear gestures to support verbal meaning, and repetition of new words in a variety of contexts ex. "see the ball", "the ball bounced"57
7888431271Molly has an IQ of 130. Molly performed better than _____ percent of her agemates.98%58

7888449757Korean toddlers develop object-sorting skills later than their English-speaking counterparts becausekorean language omits object naming things from their sentences60
7888465575Three-year-old Liam is putting together a puzzle. Liam's father begins by pointing to where each piece needs to go and then straightening out each piece as Liam places them on the puzzle board. As Liam's competence with the task increases, his father gradually withdraws support. This is an example ofscaffolding61
7888491926Which of the following statements is supported by research on make-believe play?Early make-believe is the combined result of children's readiness to engage in it and social experiences that promote it.62
