Abstract
Although the pattern of visual attention towards the region of the eyes is now well-established for infants at an early stage of development, less is known about the extent to which the mouth attracts an infant’s attention. Even less is known about the extent to which these speci c looking behaviours towards different regions of the talking face (i.e., the eyes or the mouth) may impact on or account for aspects of language development. The aim of the present systematic review is to synthesize and analyse (i) which factors might determine different looking patterns in infants during audio-visual tasks using dynamic faces and (ii) how these patterns have been studied in relation to aspects of the baby’s development. Four bibliographic databases were explored, and the records were selected following speci ed inclusion criteria. The search led to the identi ca- tion of 19 papers (October 2021). Some studies have tried to clarify the role played by audio- visual support in speech perception and early production based on directly related factors such as the age or language background of the participants, while others have tested the child’s competence in terms of linguistic or social skills. Several hypotheses have been advanced to explain the selective attention phenomenon. The results of the selected studies have led to different lines of interpretation. Some suggestions for future research are outlined.
