Narrative Skills in Swedish Children with Language Impairment.

UNLABELLED This study investigated the development of narrative skills in Swedish children with language impairment between age 5 and age 10. Seventeen children with LI and two control groups of age peers with typical development participated in a picture elicited story telling task. Analyses included measures of story content, cohesion and grammar. Our subjects showed development in different areas from age 5 to 10, but they did not perform at the level of the controls at age 10 on number of different verbs used and percent grammatically correct C-units. We conclude that preschool children with LI develop in their narrative skills over time, but not to the level of their age-peers at age 10. LEARNING OUTCOMES The reader will be able to describe areas of vulnerability in Swedish-speaking children with language impairment in general, and related to narration in particular. Furthermore, the reader will be able to describe similarities in narrative skills between Swedish-speaking and English-speaking children with language impairment.

Retention of idioms following one-time exposure

This study explored retention of idioms and novel (i.e. newly created or grammatically generated) expressions in English-speaking girls following exposure only once during a conversation. Our hypothesis was that idioms, because of their inherent holistic, nonliteral and social characteristics, are acquired differently and more rapidly than novel utterances. Two age groups of typically developing girls, 8–9 and 12–14-year-olds, were exposed to low-frequency idioms and matched novel expressions within a conversational context. Recognition and comprehension of target and nontarget idioms and novel expressions were compared following the exposure period. Ratings were obtained from participants and parents about idiom familiarity. Participants recognized significantly more target idioms than novel expressions following exposure and scored higher on comprehension of target idioms than nontarget idioms. Recognition scores did not differ significantly by age groups, but older children performed significantly better on comprehension of target idioms.

Nonword Repetition and Speech Motor Control in Children.

This study examined how familiarity of word structures influenced articulatory control in children and adolescents during repetition of real words (RWs) and nonwords (NWs). A passive reflective marker system was used to track articulator movement. Measures of accuracy were obtained during repetition of RWs and NWs, and kinematic analysis of movement duration and variability was conducted. Participants showed greater consonant and vowel accuracy during RW than NW repetition. Jaw movement duration was longer in NWs compared to RWs across age groups, and younger children produced utterances with longer jaw movement duration compared to older children. Jaw movement variability was consistently greater during repetition of NWs than RWs in both groups of participants. The results indicate that increases in phonological short-term memory demands affect articulator movement. This effect is most pronounced in younger children. A range of skills may develop during childhood, which supports NW repetition skills.

Error Type and Lexical Frequency Effects: Error Detection in Swedish Children With Language Impairment

Purpose The first aim of this study was to investigate if Swedish-speaking school-age children with language impairment (LI) show specific morphosyntactic vulnerabilities in error detection. The second aim was to investigate the effects of lexical frequency on error detection, an overlooked aspect of previous error detection studies. Method Error sensitivity for grammatical structures vulnerable in Swedish-speaking preschool children with LI (omission of the indefinite article in a noun phrase with a neuter/common noun, and use of the infinitive instead of past-tense regular and irregular verbs) was compared to a control error (singular noun instead of plural). Target structures involved a high-frequency (HF) or a low-frequency (LF) noun/verb. Grammatical and ungrammatical sentences were presented in headphones, and responses were collected through button presses. Results Children with LI had similar sensitivity to the plural control error as peers with typical language development, but lower sensitivity to past-tense errors and noun phrase errors. All children showed lexical frequency effects for errors involving verbs (HF > LF), and noun gender effects for noun phrase errors (common > neuter). Conclusions School-age children with LI may have subtle difficulties with morphosyntactic processing that mirror expressive difficulties in preschool children with LI. Lexical frequency may affect morphosyntactic processing, which has clinical implications for assessment of grammatical knowledge.

The Use of Causal Language and Filled Pauses in Children with and without Autism

This study investigated the relationship between pragmatic ability and two aspects of structural language in conversational language samples from 24 school-age children with and without high-functioning autism (HFA): causal statements and speech disruptions. In contrast to a majority of previous studies, grammatical complexity and mean length of utterance were factored into the analyses, since these are potential confounding variables. The results showed that children with HFA used fewer spontaneous causal statements and fewer filled pauses in conversation compared to children with typical development (TD). There was also a significant and positive relationship between filled pauses and pragmatic ability after controlling for structural language ability. The results may help us understand the conversational patterns of children with HFA better.
