A century of research on the development of walking has examined periodic gait over a straight, uniform path. The current study provides the first corpus of natural infant locomotion derived from spontaneous activity during free play. Locomotor experience was immense: Twelve- to 19-month-olds averaged 2,368 steps and 17 falls per hour. Novice walkers traveled farther faster than expert crawlers, but had comparable fall rates, which suggests that increased efficiency without increased cost… Expand

Figures, Tables, and Topics from this paper

The cost of simplifying complex developmental phenomena: a new perspective on learning to walk.
TLDR
It is proposed that a focus on spontaneous walking, the phenomenon the authors ostensibly wish to explain, yields important insights into the problems infants solve while learning to walk, and other areas of developmental research may also benefit from retaining the complexity of complex phenomena. Expand
Bouts of steps: The organization of infant exploration.
TLDR
It is proposed that infants' natural walking is not intentionally directed at distant goals; rather, it is a stochastic process that serves exploratory functions that limits walking skill in younger infants, but not in older infants. Expand
Where Infants Go: Real-Time Dynamics of Locomotor Exploration in Crawling and Walking Infants.
TLDR
Head-mounted eye tracking revealed that crawlers and walkers mostly take steps in place while fixating something within reach, and, although infants do not commonly go to destinations, 12-month-old crawlers go to proportionally more destinations than age-matched walkers. Expand
The Costs and Benefits of Development: The Transition From Crawling to Walking.
TLDR
An integrative analysis of the costs and benefits associated with crawling and walking is presented that challenges prior assumptions, and reveals deficits of crawling and benefits of upright locomotion that were previously overlooked. Expand
Minimizing Energy Consumption Leads to the Emergence of Gaits in Legged Robots
  • 2021
Legged locomotion is commonly studied and expressed as a discrete 1 set of gait patterns, like walk, trot, gallop, which are usually treated as given 2 and pre-programmed in legged robots forExpand
A new twist on old ideas: how sitting reorients crawlers.
TLDR
Findings indicate that sustained, linear crawling is likely an epiphenomenon of how gait is studied in standard paradigms and postural transitions between crawling and sitting are ubiquitous and can represent a functional unit of action. Expand
Use it or lose it? Effects of age, experience, and disuse on crawling
TLDR
Surprisingly, results indicate that nothing was lost with disuse, but some features of crawling were gained or altered. Expand
Carry on: spontaneous object carrying in 13-month-old crawling and walking infants.
TLDR
Sp spontaneous carrying may provide infants with new avenues for combining locomotor and manual skills and for interacting with their environments, without incurring an additional risk of falling. Expand
How do novice and improver walkers move in their home environments? An open-sourced infant’s gait video analysis
TLDR
This study presents the first data set of functional and temporal gait parameters of novice and improver infant walkers in their home environments and shows that novice infants walk with lower cadence and higher falls frequency, stance phase time and double support in their familiar environments. Expand
Variety Wins: Soccer-Playing Robots and Infant Walking
TLDR
It is proposed that robotics provides a fruitful avenue for testing hypotheses about infant development; reciprocally, observations of infant behavior may inform research on artificial intelligence. Expand

TLDR
Examination of change in locomotor responses and exploratory movements revealed a process of differentiation and selection spurred by changes in infants' everyday experience, body dimensions, and locomotor proficiency on flat ground. Expand
The road to walking: What learning to walk tells us about development
Learning to walk is one of the great achievements in human development. An aim of this chapter is to describe the developmental progression of locomotion, ranging from the spontaneous leg kicks ofExpand

  • H. Forssberg

  • 2004
TLDR
It is suggested that innate pattern generators in the spinal cord produce the infant stepping and also generate the basic locomotor rhythm in adults, but that neural circuits specific for humans develop late in ontogeny and transform the original, non-plantigrade motor activity to a plantigrade locomotor pattern.

TLDR
It is argued that a behavioral-cognitive perspective may shed light on some aspects of motor development generally, and unaided walking, specifically, and not only may a cognitive change influence motor development, but mental and motor ability may develop asynchronously in some instances. Expand
Posture and independent locomotion in early childhood: Learning to walk or learning dynamic postural control?
Abstract In this paper we suggest that early gait characteristics may be interpreted as stemming from a lack of postural control. In a review of the literature on early gait development we focus onExpand
Changes in 3D joint dynamics during the first 5 months after the onset of independent walking: a longitudinal follow-up study.
TLDR
A linear mixed model showed that with increasing walking experience, there was an increase in dimensionless walking speed, dimensionless cadence and dimensionless stride length (without correction for the increase in speed), which could be linked to the flexed position of the hip and knee during stance. Expand
What changes in infant walking and why.
TLDR
This study compared the relative contributions of growing body dimensions, age, and walking experience in the development of walking skill in 9- to 17-month-old infants, 5-6-year old kindergartners, and college students and found experience was the stronger predictor. Expand
Transition from crawling to walking and infants' actions with objects and people.
TLDR
Bidirectional influences between locomotion and object actions were found and walking was associated with new forms of object behaviors: Walkers accessed distant objects, carried objects, and approached mothers to share objects; crawlers preferred objects close at hand and shared objects while remaining stationary.

Treadmill-elicited stepping in seven-month-old infants.
  • E. Thelen

  • 1986
TLDR
6 7-month-old infants, who performed little or no stepping movements, were supported over a small, motorized treadmill and showed immediate alternating stepping, more similar to adult-like steps than newborn steps. Expand
What is the shape of developmental change?
TLDR
The findings suggest that sampling rates typically used by developmental researchers may be inadequate to accurately depict patterns of variability and the shape of developmental change, and therefore may seriously compromise theories of development. Expand
