What is the preferred type of stimuli for 4-month-olds in the preferential looking procedure?
Synchronized visual and auditory stimuli
In the study of intermodal perception, what sensory systems are often involved?
Vision and touch
In the study of combining vision and touch, what did the newborns show a preference for?
The pacifier they had sucked on
What was the outcome of the study on combining vision and touch in newborns?
Newborns looked longer at the familiar pacifier
In the study of combining vision and auditory information, what was the question being investigated?
Can infants combine vision with sound?
What did the study of combining vision and auditory info aim to understand?
Infants' ability to integrate vision with sound
What did the study of combining vision and auditory info find about newborns' ability?
Newborns can combine vision with sound
What is intermodal perception?
The coordinated perception of an object/event through multiple sensory systems
What was the method used in the study of combining vision and touch to test newborns' ability to integrate vision and touch?
Preferential looking procedure
What did the study of combining vision and touch demonstrate about newborns' ability?
Newborns can integrate visual information with touch
What did the study of combining vision and touch reveal about newborns' response to familiar objects?
Newborns looked longer at the familiar object
What is the role of motivation in motor development?
Motivation influences when motor milestones are achieved
How does motor development impact the perception of 3D objects?
Independent sitting and reaching facilitate understanding of 3D objects
How does motor development impact depth perception?
Perception of slope depends on crawling experience
What is the impact of motor development on scale errors?
Scale errors are present until around 2 years of age due to failure to integrate visual info with action planning
How does motor development influence understanding intentions in social behavior?
Motor development affects the ability to understand intentions in social behavior
What is the difference between low and high motivation infants in motor development?
Highly motivated infants move often and achieve motor milestones earlier
How does motor development impact visual development?
Motor development and visual development are interconnected, with crawling and walking influencing how crawlers and walkers see the world
What is the impact of motivation on low motivation infants in achieving motor milestones?
Low motivation infants achieve motor milestones later than highly motivated infants
What is the impact of motivation on high motivation infants in achieving motor milestones?
High motivation infants achieve all motor milestones earlier than less motivated infants
How does motor development impact infants' ability to integrate perceptual info with new motor skills?
Infants have to learn through experience how to integrate perceptual info with each new motor skill they develop
Study Notes
Infant Motor Development: Factors and Cultural Differences
- Preferential looking procedure: 4-month-olds showed preference for synchronized visual and auditory stimuli
- Reflexes: innate, adaptive actions in response to stimulation, most disappear by 2 months
- Reflexes and neurodevelopment: absent or persistent reflexes may indicate neurological problems
- Motor milestones: predictable sequence with individual variation, crawling not considered a milestone
- Cultural differences in motor development: differences in sitting and independent sitting
- Motor development encouragement: cultural practices affect opportunities and encouragement for motor development
- Diapers and walking: infants show more mature walking when naked versus wearing a diaper
- Implications of cultural differences: unintended consequences in motor development due to cultural practices
- Differences in crawling: individual variation in crawling styles due to environment and genetics
- Current theories of motor development: complex interplay between neural development, strength, perceptual skills, and motivation
- Role of weight change in motor development: weight change influences disappearance and resumption of stepping reflex
- Role of motivation: infants are intrinsically motivated to explore and learn, persist despite failing
