The context matters: The use of communicative intentions by mothers to their children during playtime and mealtime.

This study examined the use of various communicative intentions (CIs) of mothers directed to their children in two contexts: playtime and mealtime at two linguistic stages: preverbal and single-word. The study revealed that statements were most prevalent during mealtime, while both statements and directives were prevalent during playtime. Particularly, directives were more frequent during playtime than during mealtime. Moreover, the number of CIs directed to children in the preverbal stage was higher than children in the single-word stage. These findings emphasize the role of context and culture on the mother-child language use in general and CIs in particular.

The effect of hearing loss on the use of lexical categories by Hebrew-speaking mothers of deaf children with cochlear implants.

BACKGROUND AND OBJECTIVES: The frequency of use of nouns versus verbs in child-directed speech (CDS) of mothers to their normal hearing (NH) children has been investigated in various languages. Recent studies have shown that CDS to deaf children is affected by hearing loss. Thus, the main aim of the present study was to examine the effect of hearing loss on the use of content words by NH Hebrew-speaking mothers to their deaf children using CIs. The second aim was to compare the use of content words by mothers speaking to CI children to that of NH children of the same chronological age and NH children with the same hearing experience. METHOD: Three groups of mother-child dyads participated: Ten mothers of deaf children with bilateral CIs (CIs) (age range 20-48 months), ten mothers of NH children matched to the deaf children by their chronological age (NCA), and ten mothers of NH children matched to the deaf children by their hearing experience (NHE). Data were collected from mother-child dyads performing natural activities. Two hundred utterances were transcribed and analyzed both quantitatively (tokens) and qualitatively (types) according to the use of lexical categories (noun, verb, adjective, and adverb). RESULTS: The frequency of verbs and nouns, both types and tokens, was significantly higher than the frequency of adverbs and adjectives in the CDS of mothers to their children both with CIs and NH. No significant differences were found between the use of verb and noun tokens by mothers of children with NH in both groups. However, in the speech of mothers to the CI group, the use of verb tokens was significantly higher than the use of noun tokens, and the verb to noun ratio of tokens was significantly higher than that of the NHE group, and demonstrated a trend with the NCA group. CONCLUSION: The fact that mothers of CI children use more verb than noun tokens strengthens the claim that they adopt a more directive style and controlling behaviors while interacting with their CI children. Also, it seems that mothers speaking to CI children are more sensitive to the children's linguistic needs according to the hearing experience and linguistic stage rather than the chronological age. The clinical implications are discussed.

Content words in Hebrew child-directed speech.

The goal of the study was to examine whether the 'noun-bias' phenomenon, which exists in the lexicon of Hebrew-speaking children, also exists in Hebrew child-directed speech (CDS) as well as in Hebrew adult-directed speech (ADS). In addition, we aimed to describe the use of the different classes of content words in the speech of Hebrew-speaking parents to their children at different ages compared to the speech of parents to adults (ADS). Thirty infants (age range 8:5-33 months) were divided into three stages according to age: pre-lexical, single-word, and early grammar. The ADS corpus included 18 Hebrew-speaking parents of children at the same three stages of language development as in the CDS corpus. The CDS corpus was collected from parent-child dyads during naturalistic activities at home: mealtime, bathing, and play. The ADS corpus was collected from parent-experimenter interactions including the parent watching a video and then being interviewed by the experimenter. 200 utterances of each sample were transcribed, coded for types and tokens and analyzed quantitatively and qualitatively. Results show that in CDS, when speaking to infants of all ages, parents' use of types and tokens of verbs and nouns was similar and significantly higher than their use of adjectives or adverbs. In ADS, however, verbs were the main lexical category used by Hebrew-speaking parents in both types and tokens. It seems that both the properties of the input language (e.g. the pro-drop parameter) and the interactional styles of the caregivers are important factors that may influence the high presence of verbs in Hebrew-speaking parents' ADS and CDS. The negative correlation between the widespread use of verbs in the speech of parents to their infants and the 'noun-bias' phenomenon in the Hebrew-child lexicon will be discussed in detail.

The influence of contextual information on the perception of speech by postlingually and prelingually profoundly hearing-impaired Hebrew-speaking adolescents and adults.

OBJECTIVE: To study linguistic context effects on speech perception by prelingually (N = 10) and postlingually (N = 10) hearing-impaired Hebrew-speaking adolescents and adults. DESIGN: Participants were cochlear implant surgery candidates with profound sensorineural hearing loss (95 dB HL+). Four levels of speech perception materials were presented through the auditory-visual modality: monosyllabic nonsense syllables (phonological content), monosyllabic meaningful words (semantic-lexical), sentences without presented topics (semantic-syntactic), and sentences with topics (topical). Data were analyzed via percentage correct recognition and via k andj factors (Boothroyd & Nittrouer, 1988). RESULTS: Both participant groups performed better when speech material having more contextual information was presented, with no significant intergroup differences. CONCLUSIONS: This similar usage of contextual information among prelingually and postlingually hearing-impaired participants is encouraging and suggests the role of factors other than age of onset.
