Discovering the Non-prosodic Factors of Infant-Directed Speech in Language Acquisition

'Motherese' or 'Infant-Directed Speech' (IDS) has been a pivotally influential factor in language acquisition. Previous studies have identified prosodic factors of IDS which describe the acoustic features of IDS such as tempo, pitch, sound. Experimental Studies have also explained influence of IDS on the infant's brain through brain imaging techniques. Present paper aims to propose and describe the term of 'non-prosodic factors' of IDS. Through reviews and conceptual description, it aims at identifying features of IDS which accompany the acoustic features. Keywords - Cognitive Psychology, Language Acquisition, Infant-Directed Speech, Non-Prosodic Factors.
