Tactual exploration by normal infants
Insights
Infants explore their bodies through touch starting at specific ages and in a predictable sequence. This study tracked the onset of tactual exploration in normal newborns.
Area of Science:
- Developmental Psychology
- Infant Behavior
- Sensory Exploration
Background:
- Early tactile exploration is crucial for infant development.
- Understanding the sequence of body exploration provides insights into developmental milestones.
Purpose of the Study:
- To determine the age of onset for tactual exploration of various body parts in normal infants.
- To identify a potential sequence in the development of self-touch behaviors.
Main Methods:
- Observational study of 100 normal infants to record the age of onset for finger exploration of body parts (torso, knee, foot, penis).
- Daily observations of 12 newborns during the first three days of life to assess exploration of facial and head regions (mouth, face, head, ears, nose, eyes).
Main Results:
- The age of onset for tactual exploration of different body parts was recorded.
- A distinct sequence in the development of self-exploration behaviors was observed.
- Facial and head exploration was noted within the first three days of life.
Conclusions:
- Normal infants exhibit a defined age of onset for exploring body parts via touch.
- The sequence of tactual self-exploration appears to be consistent in typical infant development.
Abstract:
The age of onset for tactual exploration of the fingers, body (torso), knee, foot and penis by the fingers was determined in 100 normal infants. Exploration of the mouth, face, head, ears, nose and eyes was also studied by daily observations in the first three days of life in a second sample of 12 normal newborns, and the age of onset was recorded. The data show that the ability of the normal infant to explore by touch the various parts of his body appears to have a definite age of onset and a definite sequence.
