This study introduces a remote online paradigm for measuring infants' pointing behavior. The findings suggest that infants and caregivers spontaneously engage in pointing behavior in the online environment, and there is a relationship between parents' responses and infants' pointing frequency. Additionally, infants tend to point more to stimuli depicting faces.
Index-finger pointing is a milestone in the development of referential communication. Previous research has investigated infants' pointing with a variety of paradigms ranging from parent reports to field observations to experimental settings, suggesting that lab-based semi-natural interactional settings seem especially suited to elicit and measure infant pointing. With the Covidpandemic the need for a comparable online tool became evident enabling also efficient, low-cost, large-scale, diverse data collection. The current study introduces a remote online paradigm, based on the established live 'decorated-room' paradigm. In Experiment 1, 12-months old infants and their caregivers (N = 24) looked at digitally presented stimuli together while being recorded with their webcam. We coded pointing gestures of infants and caregivers as well as caregivers' responses to infants' pointing. In Experiment 2 (N = 47), we optimized stimuli and investigated influences of stimulus characteristics. We systematically varied the style of depiction, stimulus complexity, motion, and facial stimuli. Main findings were that infants and caregivers pointed spontaneously, with mean behaviors ranging within the benchmarks of previously reported findings of the live decorated-room paradigm. Further, the social setting was preserved as revealed by significant relations between parents' responsive points and infants' pointing frequency. Analyses of stimuli characteristics revealed that infants pointed more to stimuli depicting faces than to other stimuli. The new remote online paradigm proves a useful addition to established paradigms. It offers novel opportunities for simplified assessments, large-scale sampling, and worldwide, diversified data collection.
