Abstract
Relational developmental systems (RDS) approaches to
communicative development trace the origins of (social) pointing back to early
instances of non-social index finger use. So far, no empirical longitudinal
examination of this proposal exists. This paper reports on a longitudinal
analysis of non-social index finger use and pointing from 6 to 16 months
(n = 114) based on a parent questionnaire. We investigated
early motor abilities, cognitive abilities, caregiver sensitivity and
non-intrusiveness as potential predictors of pointing. Non-social index finger
use and pointing increased from 6 to 16 months. Non-social index finger use was
longitudinally related to pointing. Pointing was more likely to be reported with
increasing age, and when non-social index finger use was present. Early
cognitive, but not motor abilities moderated this relationship. Sensitivity and
non-intrusiveness were not related to pointing. This longitudinal study provides
empirical support for the theoretical proposal that pointing emerges from
non-social index finger use.
