PSYCH: Chapter 7
infants also categorize items on the basis of prototypes, which are
averages, extracted from the structural regularities of items
theory of mind
awareness of one's own mental processes and the mental processes of others
learning about a topsy turvy imaginary world likely helped young children
become more flexible in their thinking
imagery
creating a mental image to improve memory; using imagery to remember verbal info works better for older children
strategy construction
creation of new procedures for processing information
two other high level thinking processes in adolescence
decision making critical thinking
fuzzy trace theory dual-process model
decision making is influenced by two cognitive systems verbatim analytical gist based intuitional (very important) operate in parallel
shrinking with prefrontal cortex with aging -->
decrease in working memory and other cognitive activities in older adults
habituation
decreased responsiveness to a stimulus after repeated presentation of the stimulus
children with autism show a number of behaviors different from other children their age including
deficits in theory of mind, social interaction, and communication as well as repetitive behaviors or interests
speed with which cognitive tasks are completed improves
dramatically across the childhood years and continues to improve in early adolescence
during which years does vigilance increase the most
during preschool years older children and adolescents do show increases in vigilance tho
what influences the cognitive functioning of older adults?
education, work, health MOST IMP factors involved in understanding why cohort effects should be taken into account when studying cog functioning of older adults
working memory is an important process and resource for
effective memory
metacognition helps people perform many cognitive tasks more
effectively
processing speed is an important indicator of the ability of older adults to continue
effectively driving a vehicle
basic processes required for memory
encoding storage retrieval
changes in children's cognitive skills depend on increased skill at
encoding relevant info and ignoring irrelevant info
elaboration
engaging in more extensive processing of information includes thinking of examples, especially those related to yourself
autobiographical memories are stored as
episodic memories
cortical thickness in frontoparietal network predicts
executie function in older adults
kung children make advances in
executive and sustained attention
cognitive control
exercising effective control in a number of areas including focusing attention, reducing interfering thoughts, and being cognitively flexible increases in adolescence and emerging adulthood
expertise
extensive, highly organized knowledge and understanding of a particular domain takes a long time to obtain - in middle and older adults
developmental robotics
field using robots in examining various developmental topics and issues like motor and perceptual development, info processing, and language development

focusing on a specific aspect of experience that is relevant while ignoring the others that are irrelevant
older adults show greater activity in the ___ and ___ lobes of the brain on simple tasks
frontal and parietal BUT as attentional demands increase, older adults display less effective functioning in frontal and parietal lobes that involve cog control
encode
getting info into memory
physical brain is the computer's
hardware
self-efficacy
having confidence in one's ability to adapt their thinking to a particular situation; important for cognitive flexibility
some of the decline in intellectual performance found in older adults is likely due to
health related factors rather than to age per se
executive function is involved not only in cognitive performance, but also in
health, emotion regulation, adaptation to life's challenges, motivation, and social functioning
more complex job =
higher cognitive functioning later in life
scaffolding for older brain
involves the use of complementary neural circuits to protect cognitive functioning in an aging brain; engagement and exercise can strengthen brain scaffolding
joint attention
involves two or more individuals focusing on the same object or events
concept
key to infants cognitive development cognitive groupings of similar objects, events, people, or ideas allow you to make generalizations
declines in working memory during
late adulthood can be improved through training (some plasticity) but older adults showed less improvement than younger adults
salient versus relevant dimensions
preschool child is more likely to pay attention to stimuli that stand out even when those stimuli are not relevant to solving a problem ends at 6/7 - less impulsive, more reflection

may or not be achieved there will be considerable variation in cognitive functioning by adolescence
knowledge influences
memory influences what you notice, how you organize, represent, and interpret knowledge
fuzzy trace theory
memory is best understood by considering two types of memory representations 1 verbatim memory trace (tendency of young children) 2 gist
autobiographical memory
memory of significant events and experiences in one's life
implicit memory
memory without conscious recollection - memories of skills and routine procedures that are performed automatically
schemas

more widens in middle and late adulthood
fuzzy traces are
more enduring and less likely to be forgotten than verbatim traces contributes to improved memory and reasoning of older children
infants advances in processing information through attention, memory, and concept formation is
much richer, more gradual, and less stage like and occurs earlier than envisioned by earlier theorists like piaget

overestimate
who plays important role in development of executive function?
parents and teachers father's autonomy support parents middle, support, and scaffold skills
episodic memory
part of explicit memory retention of information about the when and where of life's happenings young adults are better at this
use it or lose it
participating in intellectually engaging activities buffers against cognitive decline
schema theory
people mold memories to fit info that already exist in their minds
from 18 months to 3 years of age, children begin to understand three mental states
perceptions: by 2 children recognize that another person will see what is in front of their eyes not what's in front of the child's eyes emotions: can distinguish between positive and negative emotions desires: refer to desires earlier and more frequently than when they refer to cognitive states like thinking and knowing
early categorizations are
perceptual categorizations based on similar perceptual features like size, color, movement, parts
infants can remember
perceptual motor information
conceptualization of metacognition includes several dimensions of executive function including
planning, evaluation (monitoring progress toward task completion), and self regulation
heavy media multitasking in adolescence is linked to
poorer memory increased impulsivity reduced volume in the brain's cerebral cortex less likely to delay gratification more likely to endorse intuitive but wrong answers
prospective memory
remembering to do something in the future declines with age - complex causes including nature of task and what is being assessed
two strategies adults can use to guide children's retention of memory
repeat with variation on instructional info and link early and often embed memory-relevant language when instructing children
once a task is automatic, it does not
require conscious effort
older children and adolescents are better than younger children at tasks that
require shifting attention
short term memory
retaining information for up to thirty seconds without rehearsal of the information using rehearsal, individuals can keep info in short term memory longer
storage
retaining information over time
patterns of neural decline with aging are more evident for
retrieval than encoding
marshmallow experiment
ring bell and get marshmallow or wait and get two from the instructor young children who waited used a number of strategies to distract themselves from the marshmallow (cool thoughts_
2 wats that the preschool child's control of attention is deficient
salient vs relevant dimensions playfulness
a preschool child's ability to control and sustain their attention is related to
school readiness and achievement
educational experiences are positively correlated with
scores on intelligence tests and info processing tasks better cognitive functioning
micro genetic method
seeks to discover not just what children know, but the cognitive processes involved in how they acquire the knowledge
dimensions of executive function that are the most important for 4 to 11 year old children's cognitive development and school success
self control working memory flexibility
children's information processing is characterized by
self modification children learn to apply what they have learned in previous circumstances to adapt their responses to a new situation
what escapes memory decline

time based tasks, not event based tasks
joint attention skills are frequently observed
toward the end of the first year
executive function

3 - 5 year olds _____ when mental activity is likely to take place and their understanding of their own thinking is _____
underestimate linking
reminiscence bump
when adults remember more events from the second and third decades of their lives than other decades; found more for positive than negative life events mostly occurs for personal events but can occur with high impact public events
tip of the tongue phenomenon
when individuals can't quite retrieve familiar information
infantile amnesia
when you cannot remember stuff from your first three years of life; starts around 9 years old
factors that influence the accuracy of a young child's memory
younger children are more susceptible to suggestion there are individual differences to susceptibility too (increased susceptibility is linked to low self concept, low support from parents, mother's insecure attachment in romantic relationships) interviewing techniques can produce substantial distortions in children's reports about highly salient events
