How Babies Use Object Permanence To Get What They Want
2022: A report from the journal: Pediatric Physical Therapy
Regina Harbourne PhD, PT, PCS, FAPTA, Associate Professor in the Department of Physical Therapy at Rangos School of Health Sciences, in Duquesne University, Pittsburgh USA, talks about her group’s research investigating motor and cognitive development in infants and small children by examining “object permanence”-the child’s ability to work out for themselves that an object continues to exist even though they cannot see or feel it.

PURPOSE:
This study examines object permanence development in infants with motor delays (MD) compared with infants with typical development (TD) and in relation to sitting skill.
METHODS:
Fifty-six infants with MD (mean age = 10 months) and 36 with TD (mean age = 5.7 months) were assessed at baseline and then at 1.5, 3, and 6 months postbaseline. A scale was developed to measure object permanence (Object Permanence Scale [OPS]), and the Gross Motor Function Measure sitting subsection (GMFM-SS), and the Bayley Scales of Infant and Toddler Development, 3rd Edition (Bayley-III) were administered.
Results:
Interrater reliability of the OPS was excellent and correlation between the OPS and Bayley-III cognitive scores was moderately positive. Compared with TD, infants with MD were delayed in development of object permanence but demonstrated increased understanding over time and as sitting skills improved.
CONCLUSIONS:
In children with MD, object permanence, as quantified by the OPS, emerges in conjunction with sitting skill.
