Twenty preschoolers with specific language impairment (SLI) and 20 age matches with normal language (NL) participated in a study to determine whether phonological memory or semantic knowledge predicted word-learning success. Poor learners’ performance was analyzed to investigate whether phonology or semantics contributed more to word-learning difficulty. Results suggest that existing lexical knowledge, as measured by the Peabody Picture Vocabulary Test (PPVT-III), and fast-mapping ability hold promise for identifying poor word learners, but individual PPVT-III scores must be compared with SLI group scores. Poor word learners comprehended most new words and showed sufficient semantic knowledge of their referents to draw them but had difficulty producing the words. Findings indicated that both semantics and phonology contribute to word-learning difficulty, with word production presenting the biggest hindrance to success.

The Relationship

Thirty preschool children with specific language impairment (SLI) and 30 agematched controls with normal language (NL) participated in a study to compare group performance and to examine the relationship between fast mapping and word learning and between comprehension and production of new words. The groups performed similarly on the fast-mapping task. The NL group comprehended and produced significantly more words than the SLI group, and did so in fewer trials. Language test scores did not predict word-learning performance for either group. Some children with SLI may need to hear a new word twice as many times as their NL peers before comprehending it and may need twice as many opportunities to practice producing the word before using it independently.

The Impact

This investigation examined the influence of emphatic stress on children's novel word learning. Forty school-age children participated in this study, including 20 children with specific language impairment (SLI) and 20 children with normal language (NL) development. Results indicated that there were no significant stress effects for comprehension or recognition of novel words (for which all children demonstrated relatively high levels of performance); however, children in both groups exhibited significantly better production of words that had been presented with emphatic stress than with neutral stress. These findings are discussed within a limited capacity framework of language processing.

The Relationship

The learning of a new word involves at least two processes: learning from input and memory evolution in the absence of input. The authors will review the literature and describe the relationship between these two processes and novel word learning by children with specific language impairment (SLI). Cases from an ongoing preliminary clinical trial of word learning in kindergarten children with SLI will serve as clinical illustrations. In particular, one case will be used to demonstrate a pattern of good learning from input and good memory retention (i.e., desirable learning pattern during treatment). Three additional cases will be used to illustrate patterns indicative of poor learning from input and/or poor memory retention. Suggestions will be provided concerning how treatment can be altered when these patterns appear, to promote desirable learning outcomes.

AbstractResearch has shown that observing iconic gestures helps typically developing children (TD) and children with specific language impairment (SLI) learn new words. So far, studies mostly compared word learning with and without gestures. The present study investigated word learning under two gesture conditions in children with and without language impairment. Twenty children with SLI (age four), twenty age-matched TD children, and twenty language-matched TD children were taught words that were presented with either iconic or non-iconic gestures. Results showed that children of all groups benefited more successfully from observing iconic gestures for word learning. The iconic gesture advantage was similar across groups. Thus, observing iconic gestures prompts richer encoding and makes word learning more efficient in TD and language impaired children.

Experimental Training

Purpose Variability in the input plays an important role in language learning. The current study examined the role of object variability for new word learning by preschoolers with specific language impairment (SLI). Method Eighteen 4- and 5-year-old children with SLI were taught 8 new words in 3 short activities over the course of 3 sessions. Half of the children saw 3 identical objects corresponding to each new word during training (No Variability group); the other half of the children saw 3 different objects corresponding to each new word during training (High Variability group). Children completed vocabulary learning tests for objects seen during training and for new within-category objects that were never seen during training as a test of category generalization. Learning was assessed the day after each training activity, and retention was assessed 3 weeks after the last training session. Results There were no group differences on trained or generalization items immediately following training sessions. However, children in the High Variability group demonstrated significantly better retention 3 weeks after experimental training. Conclusion These findings demonstrate that object variability facilitates retention of new word learning by children with SLI. Supplemental Material https://doi.org/10.23641/asha.5583979

The present study investigated whether children with specific language impairment (SLI) differed from children with normal language learning in their ability to process binaural temporal information. The SLI group was matched with peers of the same chronological age, as well as peers with similar language age. All three subject groups were tested with measures of complex sound localization involving the precedence effect phenomenon. Subjects were required to track the apparent motion of a “moving” fused auditory image (FAI). Movement of the FAI was simulated by varying the delay incrementally between pairs of clicks presented, one each, from two matched loudspeakers placed on opposite sides of the child’s head. With this task, the SLI subjects’ performances were found to be similar to their language age-matched but chronologically younger peers. Both groups exhibited tracking skills that were statistically poorer than that of the chronologically age-matched group. Additional tests indicated this effect was not due to differences in motoric tracking abilities nor to the SLI subjects’ abilities to perceive small binaural time cues. Thus, children with SLI appear to be impaired in their ability to use binaural acoustic information in a dynamic ongoing fashion. The requirements for processing such nonlinguistic acoustic information in a “dynamic and ongoing” fashion may be similar to those involved in the ongoing processing of rapid changes in the temporal and spectral components of the speech chain.

Ten children with specific language impairment and 10 children with normal language development were asked to describe objects so that a listener could select them. Each trial targeted two out of a group of three toys. The targeted objects were identical or were similar in size or color. Children in the two groups did not differ in referential success, although children in both groups found the size items more difficult. Content analysis of the messages did reveal differences in the referential strategies used most frequently. Children with specific language impairment were more likely to mention the attributes of each object separately, rather than to describe the characteristics common to a pair of objects. Children in both groups talked about separate objects more often when talking about size than about color or object type. Use of this strategy could indicate the effects of attentional capacity on children's solutions to communication tasks.

Peer Models

This investigation included two phases of inquiry that examined the effects of peer modeling upon the play scripts of children with specific language impairment (SLI). The first study employed a pretest-posttest control group design involving two groups of children with SLI (10 who participated in the experimental treatment and 10 controls) and a group of peer models (10 children with normal language development). The treatment involved dyadic play sessions in which children with SLI were paired with a normal language peer model. Significant differences were found between the play script reports of the experimental (SLI-E) and control groups (SLI-C) of children with specific language impairment. The second study, utilizing single-case methodology, involved 6 children with SLI who participated in the control group of Study 1, plus 2 peer models. Play dyads consisted of either two children with SLI or one child with SLI and a normal language peer. Results of this study provided support for the contention that play interactions with normal language peers facilitates increases in the play-script reports of children with SLI.
