Developmental continuity? Crawling, cruising, and walking.
This research examined developmental continuity between "cruising" (moving sideways holding onto furniture for support) and walking. Because cruising and walking involve locomotion in an upright posture, researchers have assumed that cruising is functionally related to walking. Study 1 showed that most infants crawl and cruise concurrently prior to walking, amassing several weeks of experience ...
متن کاملPhonetic abilities of walking and crawling infants
Infants undergo a series of dynamic changes during the first year of their life, starting at nearly complete dependence upon others for all functions, culminating with the ability to self-transport and rudimentarily converse around the age of 12 months. Previous research indicates an interaction between walking and expressive and receptive language development. Given that phonology underlies ex...
متن کاملKinesin: walking, crawling or sliding along?
Kinesins are microtubule-based motor proteins that are involved in cargo transport and mitosis. They are called "motors" because they convert chemical energy to mechanical energy (i.e. force and motion). They use the energy of ATP hydrolysis for their enzymatic processes by walking on microtubules. However, the mechanism underlying their motion has been unclear. Recently, conventional kinesin, ...
متن کاملCrawling and walking infants see the world differently.
How does visual experience change over development? To investigate changes in visual input over the developmental transition from crawling to walking, thirty 13-month-olds crawled or walked down a straight path wearing a head-mounted eye tracker that recorded gaze direction and head-centered field of view. Thirteen additional infants wore a motion tracker that recorded head orientation. Compare...
متن کاملCrawling and walking infants elicit different verbal responses from mothers.
We examined mothers' verbal responses to their crawling or walking infants' object sharing (i.e. bids). Fifty mothers and their 13-month-olds were observed for 1 hour at home. Infants bid from a stationary position or they bid after carrying the object to their mothers. Mothers responded with affirmations (e.g. 'thank you'), descriptions ('red box'), or action directives ('open it'). Infants' l...
