Chapter 6 Flashcards
(40 cards)
Sensation
Process by which senosry receptor neurons detect information transmit it to the brain
Perception
The interpretation of sensory input(recognizing the information)
Constructivist (side of nuture)
Perceptions are consturcted through learning
Nativist(side of nature)
Innate capabilities and maturational drive perceptual development
Perception doesn’t require interpretation
Gibson’s Ecolgoical Theory of perception
Nature vs Nuture are inseparable
Perception drives action
how does babies sense and perceive
Hibituation paradigm
Same stimulus —> eventually the baby will lose interest in object
How does babies sense and perceive
Preferenatial paradigm
Two stimulus against each other, which one the baby looks at longer
How does babies sense and perceive
EEG
records the brain activtiy of the baby while there’s a simulus
Vision
Eyes takes in stimulation in form of light, converts information to signals that’s sent to the brain, brain interpret the signal
Infant’s visual attention
Patterns with large contour attracts attention
Displays that are dynamic
Patterns that are moderately complex
High complex is too much for baby
Likes to look new things over old things
infant auditory recognition
look longer at the source of familiar sounds compared to novel(Stranger) sounds
6 months = universal listener
10 months = stops being the universal listener
Face process infants
1 month old focus on top of the head
2 month focus more on the central of the face( more information)
Infants’ depth perception
Infants of crawling age can clearly perceive depth
Not born with
Demonstrated by visual cliff experiement
Infant hearing
Hearing is more develop than vision at birth,
localize hearing
Look towards soft sounds, but look away from loud sounds
Conjugating reinforcement technique
testing of the long term memory and perceptual information
child’s foot attracted to a ribbon on the crib
Infants
Taste and smell(Chemical Sense)
Babies can distinguish sweet, bitter, and sour
Sense of smell is well developed at birth
Different kinds of food = less picky eater(between 4 -6 months)
Exposure to fimiliar scent = calming
Infant body sense(somaesthetic)
Touch, temperature, pain, and kinethetic sense
Pretty well developed at birth
Unable to regulate body temperature
Childhood
Locomotion
allows the children to move from one place to another
Develop gross motor skills before fine motor skils
When does Infant engage in rhythmic stereotypes behavior
Before a new motor skill emerges, but not after
Rocking, swaying, banging arms up and down
Dynamic systems Theory
Developments take place over time through a “self-organizing” process
Use senosry feedback when trying different movements to modify their motor behvaior
Cross-modal perception
Increases across childhood, Recognize through one sense an object familiar through another
Recognizing an object through mulitple senses
Orienting system
Reacts to the events in the environment
Focusing system
Deliberately seeks out and maintains attention to events
Adolescent attention
Longer than children
Increased myelination of the brain that help regulate attention
Become more efficient at ignoring irrelevant information
Not good at multitasking, those who said they are confident in multitasking can’t see their own mistakes(Overfident bias)
