Description: Used High-amplitude sucking procedure to investigate 2-month-olds' memory for sets of four bisyllables that share a common syllable. Examined the effect of stress and position of the shared syllable on infants' memory for the bisyllables.

Age:4.5 mo

Description: Using the headturn preference procedure, we explored the changing nature of infants' name representations and their potential use in attaining other language-processing milestones. Experiments 1 - 3 explored the specificity of name representations and infants' responsiveness to other socially-salient items. Experiments 4 - 6 moved beyond recognition of socially-salient patterns, and tested the effects of
name recognition in on-line processing, such as name detection in fluent
speech contexts and its potential role in to segmenting other words. Results suggest that names may be special lexical items which are recognized earlier and in more detail than other words during early stages of language learning.

Description: Infants 4.5 months of age are hypothesized to be in the "initial state" for acquisition, which in Optimality Theory means their grammars rank all markedness constraints above any faithfulness constraints. We investigated their sensitivity to nasal place assimilation as a means of comparing two versions of OT: the standard version of Alan Prince and Paul Smolensky, and the "Targeted OT" of Colin Wilson.

Age:6 mo

Description: The Headturn Preference Procedure is used to examine young infants’ sensitivity to clausal units in languages with different prosodic and syntactic properties. The degree of tuning to the input language in the performance of these tasks is then assessed. In addition, infants’ performance with non-language stimuli is also assessed in order to ascertain which aspects of performance are linguistic in origin and which are more general properties of learning about auditory stimuli.

Description: Previous work (Tincoff & Jusczyk, 1999) demonstrated that 6-month-olds can link the sound patterns "Mommy" and "Daddy" to video images of the appropriate parents, but do not attach these words to unfamiliar men and women. Using a preferential looking procedure, the current study extends these findings by showing that 6-month-olds can attach sound patterns of the familiar spoken words (“Hands” and “Feet”) to instances of these referents that they had never seen.

Description: Do infants need to know the language to recognize the familiar word patterns in continuous speech? Specifically, after being familiarized with words in a foreign language, will they detect them in the fluent speech of that language?

Description: Children were presented with approximately 5 hours of videotaped exposure to Mandarin Chinese prior to visiting the laboratory. They then were tested in the same procedure as that of Tsay and Jusczyk, using stimuli in Mandarin. If this amount of exposure is sufficient for infants to begin acquiring segmentation skills, we would expect that infants in the present study would perform better at the segmentation task than did infants without such exposure (those in the prior study by Tsay and Jusczyk).

Description: Using the HPP, this study extended Jusczyk and Aslin (1995) by familiarizing 7.5-month-olds with nonwords (e.g., [beyp]) and then presenting test passages containing words that differ from the nonwords in their final consonant (e.g., 'bike', [beyk]) along with new unfamiliar words. The infants did not false alarm to the test passages containing the similar sounding words. Our results suggest that infants have detailed phonetic representations of familiar sound patterns.

Description: We familiarize English-learning 8-month-olds with the same language used by Johnson and Jusczyk (2001). During the test phase, infants are tested on their listening preferences to two types of stimuli: 1) the first two syllables of a statistical word, 2) the last two syllables of a statistical word.

Description: We familiarize English-learning 8-month-olds with a modified version of the artificial language used by Saffran et al. (1996). However, the language used in the current study contains words of variable length. Results indicated that infants failed to segment this more complex type of artificial language. Thus, the results of the current study suggest that we must expand our accounts to ask how infants’ statistical learning prowess could be realistically applied in the domain of early word segmentation.

Description: Forty-eight 9-month-olds were tested on two types of stimuli. Alternating Structure stimuli comprised pairs of sentences that contained the same subject NP but exhibited different structures (S-V-NP and S-V-S). Same Structure stimuli comprised pairs of sentences that contained the same subject NP and exhibited the same sentence structure (either S-V-NP or S-V-S). The results showed that infants preferred Alternating over Same Structure stimuli, but this preference was only significant when the Same Structure stimuli were S-V-S.
