The purpose of this study was to assess characteristics of the growth of language in Swedish 7-15 months-old infants. More scpecifically, to estimate vocabulary composition (the 1st part of the study), information on 24 infants’ comprehension and production of speech was collected, and to investigate the role of adult-instructions for early word-learning ( the 2nd part of the study) video recordings of infant-adult interaction-dyads were produced. The vocabulary-data were collected based on parental reports using the Swedish version of the MacArthur Communicative Development Inventory. The subjects’ size of receptive and productive vocabulary across five semantic categories were estimated in a longitudinal perspective based on 45 completed forms. The infant-adult interaction data was likewise collected in a longitudinal perspective. The variables chosen for analyses of infant-adult interaction were: objective of the parent’s gestural instruction, objective of the parent’s vocal instruction, and focus of attention of the infant. The 1st part of the study showed an immense progress for comprehension within the receptive semantic categories of ‘phrases’ and ‘sounds’. The results for the 2nd part of the study showed a shift along a time axis from gestural instructions being mostly correlated with the attentional focus of the infant (at 7 months) to gestural and vocal instructions being equally common (at 15 months). A discussion on significance of these results will round off the paper.
