Mental state verb use in play by preschool-age children who stutter and their mothers.

INTRODUCTION: Preschool-age children use mental state verbs (MSVs; e.g., think, know) to reference thoughts and other cognitive states. In play-based language, MSV use requires conversational flexibility, as speakers shift from discussion of actions happening in the here-and-now to more abstract discussion of mental states. Some evidence suggests that children who stutter (CWS) demonstrate subtle differences in shifting on experimental tasks of cognitive flexibility, differences which may extend to conversational flexibility. This study explored MSV use in conversational language between CWS and their mothers. METHODS: Thirty-five preschool-age CWS and 35 age- and gender-matched children who do not stutter (CWNS), all performing within the typical range on standardized language testing, conversed with their mothers during play. Samples were transcribed and coded for MSV use. RESULTS: No between-group differences were observed in MSV use, either between the CWS and CWNS or between the groups of mothers. Age and language skills were positively associated with MSV use in the CWNS group only. For both groups of dyads, mothers' MSV use corresponded at least to some extent to their children's language skills. Finally, correspondence between CWNS and their mothers was observed for two conversational language measures, representing lexical diversity and morphosyntax; this overall pattern was not observed in the CWS dyad group. CONCLUSIONS: Although these findings point to similar use of MSVs among the groups of children and their mothers, for the CWS group, the patterns of use in relation to age and language skills are somewhat different from developmental expectations.

Caregiver-reported impact of access to switch-adapted toys on play for children with complex medical conditions.

BACKGROUND: Play is essential for children's development of motor, social-emotional and cognitive skills. Traditional play activities are often difficult for children with complex medical conditions to access, which threatens their ability to maximize their developmental potential. Switch-adapted toys are a common strategy for expanding the play repertoire of children with disabilities by lowering the barrier to play with electronic toys. The aim of this study is to investigate the relationship between providing switch-adapted toys to children with disabilities and the children's total and self-initiated play time and access to a variety of cognition-appropriate toys, age-appropriate toys and independently accessible toys as reported by their caregivers. METHODS: Caregivers and their children with complex medical conditions were provided switch-adapted toys at a giveaway event. At the giveaway event and 6 months later, caregivers completed a survey that included questions about each child's current participation in play and their type of play, child's access to toys and questions specific to switches and switch-adapted toys. Data were analysed using Wilcoxon signed-rank tests with a Benjamini-Hochberg procedure to control for multiple comparisons. RESULTS: Nineteen caregivers completed both the pre- and post-surveys. The increases in the variety of toys and the number of independently accessibly and cognitively appropriate toys were statistically significant. The change in number of age-appropriate toys and the amount of total and active play time were not statistically significant. CONCLUSIONS: Providing switch-adapted toys may be an effective way to increase the number of independently accessible and cognitively appropriate toys for children with complex medical conditions. However, increasing the number of such toys may not be sufficient to increase active and total play time. Further research is needed to identify variables impacting play time and distal outcomes associated with switch-adapted toy access.

A Comparative Study of Auditory-Perceptual Speech Measures for the Early Detection of Mild Speech Impairments.

BACKGROUND AND PURPOSE: The aim of the study was to compare transcription-based speech intelligibility and scaled speech severity for the detection of mild speech impairments, by studying these metrics across talkers with Parkinson's disease (PD), age- and sex-matched older adults, and younger adults. An additional aim was to determine the impact of listener experience on these clinical measures. METHODS: Fifteen speakers from each experimental group were asked to read aloud 11 randomly generated sentences from the Speech Intelligibility Test at their typical speaking rate and loudness. Two groups of four listeners each, stratified as experienced or inexperienced listeners based on their clinical experience, judged the sentence samples. To estimate intelligibility, both listener groups were asked to orthographically transcribe exactly what they heard for each sentence. For severity estimates, the listener groups were asked to rate the sentences for overall quality based on voice, resonance, articulation, and prosody, using a visual analog scale. RESULTS: Transcription-based intelligibility and scaled severity scores of the PD group differed significantly from those of the older and younger adults. Between-age group differences in intelligibility and scaled severity were not observed. Listener experience had an impact on scaled speech severity, but not speech intelligibility. Between-group differences in speech severity were driven by the inexperienced group and not the experienced listener group. IMPLICATIONS: Both transcription-based intelligibility and scaled severity estimates appear to be sensitive to relatively mild speech impairments in PD. Obtaining scaled severity is less labor intensive than transcription; therefore, visual analog scaling may be the preferred paradigm for clinical use. However, listener experience and training are important considerations for scaling techniques to be implemented clinically.

Foundations of Arrogance: A Broad Survey and Framework for Research.

We consider the topic of arrogance from a cross-disciplinary viewpoint. To stimulate further research, we suggest three types of arrogance (individual, comparative, and antagonistic) and six components contributing to them, each logically related to the next. The components progress from imperfect knowledge and abilities to an unrealistic assessment of them, an unwarranted attitude of superiority over other people, and related derisive behavior. Although each component presumably is present to some degree when the next one operates, causality might flow between components in either direction. The classification of components of arrogance should reduce miscommunication among researchers, as the relevant concepts and mechanisms span cognitive, motivational, social, and clinical domains and literatures. Arrogance is an important concept warranting further study for both theoretical and practical reasons, in both psychopathology and normal social interaction. Everyone seems to have qualities of arrogance to some degree, and we consider the importance of arrogance on a spectrum. We contend that humankind can benefit from a better understanding of the cognitive limitations and motivational biases that, operating together, appear to contribute to arrogance. We bring together information and questions that might lead to an invigorating increase in the rate and quality of cross-disciplinary research on arrogance.
