The Role of Verbal Repetition in the Development of Infant Speech Preferences From 4 to 14 Months of Age
Four experiments investigated infants' preferences for age‐appropriate and age‐inappropriate infant‐directed speech (IDS) over adult‐directed speech (ADS). Two initial experiments showed that 6‐, 10‐, and 14‐month‐olds preferred IDS directed toward younger infants, and 4‐, 8‐, 10‐, and 14‐month‐olds, but not 6‐month‐olds, preferred IDS directed toward older infants. In Experiment 3. 6‐month‐olds preferred IDS directed toward older infants when th…
Signs of Pretense Across Age and Scenario
Participation in imagined worlds is a hallmark of the human species, and yet we know little about the context of its early emergence. The experiments reported here replicated and extended in 2 directions Lillard and Witherington's (2004) study of how mothers pretend to have snacks, across different ages of children (15‐ to 24‐month‐olds, Experiment 1) and to a different scenario (personal grooming, Experiment 2). Mothers' pretend behaviors change…
Infant Perception of Non-Native Consonant Contrasts that Adults Assimilate in Different Ways
Numerous findings suggest that non-native speech perception undergoes dramatic changes before the infant's first birthday. Yet the nature and cause of these changes remain uncertain. We evaluated the predictions of several theoretical accounts of developmental change in infants' perception of non-native consonant contrasts. Experiment 1 assessed English-learning infants' discrimination of three isiZulu distinctions that American adults had catego…
Discrimination of non-native consonant contrasts varying in perceptual assimilation to the listener’s native phonological system
Classic non-native speech perception findings suggested that adults have difficulty discriminating segmental distinctions that are not employed contrastively in their own language. However, recent reports indicate a gradient of performance across non-native contrasts, ranging from near-chance to near-ceiling. Current theoretical models argue that such variations reflect systematic effects of experience with phonetic properties of native speech. T…
Rapid Gains in Speed of Verbal Processing by Infants in the 2nd Year
Infants improve substantially in language ability during their 2nd year. Research on the early development of speech production shows that vocabulary begins to expand rapidly around the age of 18 months. During this period, infants also make impressive gains in understanding spoken language. We examined the time course of word recognition in infants ages 15 to 24 months, tracking their eye movements as they looked at pictures in response to famil…
Accommodation in mean f 0 during mother–infant and father–infant vocal interactions
Reports that infants imitate the vocal pitch characteristics of adult caregivers (e.g. Lewis, 1936/1951) include Lieberman's (1967; Lieberman, Ryalls & Rabson, 1982) claim that infants differentially adjust their vocal pitch or fundamental frequency (f 0 ) towards that of their caregivers, resulting in higher mean pitch when interacting with mothers than when interacting with fathers. However, a recent cross-sectional study of infants at ages 0;8…
