“…Second, a perceptual CL bias might be more difficult to learn than a perceptual LC bias, because it goes against what appears to be a language-general production LC bias (which will however need to be further evaluated in future studies), as is suggested for Japanese by the adults data obtained by Tsuji et al (2012). These opposed production/perception biases might make the learning of these phonotactic dependencies more difficult, since several studies have shown the importance of the perception-production link (see Vihman, 1993;Vihman & Croft, 2007;Yeung & Werker, 2013) and the influence of production experience on infant speech processing (Keren-Portnoy, Vihman, DePaolis, Whitaker, & Williams, 2010;DePaolis, Vihman, & Keren-Portnoy, 2011;DePaolis, Vihman, & Nakai, 2013;Majorano, Vihman, & DePaolis, 2014). These different explanations are likely to be non-mutually exclusive, in particular in light of the fact that French-learning infants have been found to acquire a CL bias for fricative sequences without any developmental lag (e.g., by 10 months), a case that crucially differs from the present case in the fact that the input patterns were much clearer.…”

a b s t r a c tPrevious studies have described the existence of a phonotactic bias called the Labial-Coronal (LC) bias, corresponding to a tendency to produce more words beginning with a labial consonant followed by a coronal consonant (i.e. ''bat'') than the opposite CL pattern (i.e. ''tap''). This bias has initially been interpreted in terms of articulatory constraints of the human speech production system. However, more recently, it has been suggested that this presumably language-general LC bias in production might be accompanied by LC and CL biases in perception, acquired in infancy on the basis of the properties of the linguistic input. The present study investigates the origins of these perceptual biases, testing infants learning Japanese, a language that has been claimed to possess more CL than LC sequences, and comparing them with infants learning French, a language showing a clear LC bias in its lexicon. First, a corpus analysis of Japanese IDS and ADS revealed the existence of an overall LC bias, except for plosive sequences in ADS, which show a CL bias across counts. Second, speech preference experiments showed a perceptual preference for CL over LC plosive sequences (all recorded by a Japanese speaker) in 13-but not in 7-and 10-month-old Japanese-learning infants (Experiment 1), while revealing the emergence of an LC preference between 7 and 10 months in French-learning infants, using the exact same stimuli. These crosslinguistic behavioral differences, obtained with the same stimuli, thus reflect differences in processing in two populations of infants, which can be linked to differences in the properties of the lexicons of their respective native languages. These findings establish that the emergence of a CL/LC bias is related to exposure to a linguistic input.

“…Impaired phonological working memory (PWM) is thought to underlie speech and language difficulties because it underlies the creation of phonological representations [22]. Recent research, however, suggests that PWM is dependent upon the ability to assemble phonology for speech output [23]. Children were better able to repeat non-words that contained consonants and consonant combinations that they used frequently as opposed to non-words constructed of infrequently used consonant sequences.…”

Theoretical accounts and clinical management of pediatric speech sound disorders (SSD) are limited by previous research. Participants' speech difficulties have been inadequately described, reflecting the lack of clarity in existing diagnostic guidelines. Performance measures have primarily focused on the articulation of consonants in single words rather than phonological competence and the cognitivelinguistic abilities underlying speech development. Evidence-based practice reviews conflate studies of heterogeneous speech-disordered populations who received widely differing amounts of therapy using different intervention approaches. More recently, however, researchers have begun to explore assessment measures that allow differential diagnosis of subgroups of SSD in terms of qualitative analyses of speech errors and underlying cognitive linguistic abilities. These measures have allowed long-term follow-up to better predict which children will have future literacy difficulties and to identify specific underlying deficits that inform intervention.

“…The impact of this link beyond the preference or dispreference for favorite consonants is an open question and should be explored further. For example, future work could examine how the relationship between production and perception affects the ability to attach meaning to word forms that either do or do not contain preferred production patterns (see Keren-Portnoy et al, 2010, for a study investigating phonological memory and preferred production patterns). Models could also incorporate proprioceptive feedback into the developmental trajectory of consonant and vowel categorization (for examples see models by Kent, 1981, andWestermann &Miranda, 2004).…”

“…They found that the use of at least two VMS was a prerequisite for the transition into referential word use in the 20 children they observed. In the same way that self-produced locomotion facilitates the development of spatial awareness, the ability to produce consistent patterns in babble can be taken to support memory for word forms (Keren-Portnoy, Vihman, DePaolis, Whitaker, & Williams, 2010), which in turn facilitates the recognition that a word form can symbolize events or entities in the world.…”

The headturn preference procedure was used to test 18 infants on their response to three different passages chosen to reflect their individual production patterns. The passages contained nonwords with consonants in one of three categories: (a) often produced by that infant (ÔownÕ), (b) rarely produced by that infant but common at that age (ÔotherÕ), and (c) not generally produced by infants. Infants who had a single ÔownÕ consonant showed no significant preference for either ÕownÕ (a) or ÔotherÕ (b) passages. In contrast, infantsÕ with two ÔownÕ consonants exhibited greater attention to ÔotherÕ passages (b). Both groups attended equally to the passage featuring consonants rarely produced by infants of that age (c). An analysis of a sample of the infantdirected speech ruled out the mothersÕ speech as a source of the infant preferences. The production-based shift to a focus on the ÔotherÕ passage suggests that nascent production abilities combine with emergent perceptual experience to facilitate word learning.

The Role of Vocal Practice in Constructing Phonological Working Memory

Abstract: Performance depended on familiarity with words or their subunits and was strongest for real words, weaker for in words, and weakest for out words. The results demonstrate the important role of speech production in the construction of phonological working memory.
