Purpose Many children with developmental language disorder (DLD) have weaknesses in executive functioning (EF), specifically in tasks testing interference control and working memory. It is unknown how EF develops in children with DLD, if EF abilities are related to DLD severity and persistence, and if EF weaknesses expand to selective attention. This study aimed to address these gaps. Method Data from 78 children with DLD and 39 typically developing (TD) children were collected at three times with 1-year intervals. At Time 1, the children were 5 or 6 years old. Flanker, Dot Matrix, and Sky Search tasks tested interference control, visuospatial working memory, and selective attention, respectively. DLD severity was based on children's language ability. DLD persistence was based on stability of the DLD diagnosis. Results Performance on all tasks improved in both groups. TD children outperformed children with DLD on interference control. No differences were found for visuospatial working memory and selective attention. An interference control gap between the DLD and TD groups emerged between Time 1 and Time 2. Severity and persistence of DLD were related to interference control and working memory; the impact on working memory was stronger. Selective attention was unrelated to DLD severity and persistence. Conclusions Age and DLD severity and persistence determine whether or not children with DLD show EF weaknesses. Interference control is most clearly impaired in children with DLD who are 6 years and older. Visuospatial working memory is impaired in children with severe and persistent DLD. Selective attention is spared.

This study aims to advance the understanding of the impact of the discursive context in the form-function mappings of aller + V forms by native speakers (NSs) and learners of French (NNSs), and to further knowledge about the developmental patterns of use of such forms at three proficiency levels (lower intermediate, upper intermediate, and advanced). While aller + V is often referred to as a periphrastic future form, i.e., a way to express temporal reference, it also takes a range of diverse semantic values (including spatial, aspectual, and modal values), and discursive functions. We therefore set out to examine data from a cross-sectional oral narrative and a longitudinal semi-guided interview task to find out to what extent aller + V forms are used by NSs and NNSs in a study abroad context. Our main results show that at lower intermediate level, spatial values dominate, while temporal and modal values emerge at upper intermediate and advanced levels. As regards the discursive functions of aller + V, learners make context appropriate choices (among others, narrative function in oral narratives, and stance-marking in interviews), but even at advanced level, their range of semantic values and discursive functions is more restricted than native speakers’.

AbstractRecent decades have seen an alarming increase in rates of suicide among young people, including children and adolescents (“youth”). Although child maltreatment constitutes a well-established risk factor for suicidal ideation in youth, few efforts have focused on identifying factors associated with maltreated youths’ increased risk for suicidal ideation, especially across development. The present study examined the relations between maltreated youths' (N = 279, M = 12.06 years, 52% female, 53% Latinx) perceptions of their social status and suicidal ideation and compared those relations between pre-adolescents and adolescents. Findings revealed unique developmental patterns: Perceived social status was associated with suicidal ideation, but only in adolescents, who showed greater risk for suicidal ideation if they viewed themselves as lower ranked in society and lower risk for suicidal ideation if they viewed themselves as higher ranked in society. Findings have implications for scientific and practical efforts aimed at better understanding and preventing suicide in a high-risk developmental population.

Past research demonstrates a strong link between drug use and crime among justice-involved adolescents, yet little is known about the joint development between drug use variety and various types of criminal offending frequencies from adolescence to young adulthood. Using a sample of male adolescent offenders ( N = 842), this article examines the coevolution of drug use variety and three separate types of offending frequencies. First, four group-based trajectory models identify unique group developmental patterns for drug use variety, drug sales offending, property offending, and violent offending. Next, three dual-trajectory models examine the coevolution between drug use variety and each type of criminal offending. Findings reveal a general pattern of desistance for both drug use and offending, while also illustrating notable variability in group trajectory patterns for drug use variety and criminal behavior. This article concludes that adolescents with elevated drug use variety make up a large proportion of frequent offenders.

The purpose of this study was to determine whether the auditory perceptual abilities of children are characterized by an age-related improvement in duration discrimination. Forty children, ages 4 to 10 years, and 10 adults served as subjects. Difference limens were obtained using a 350-msec broadband noise burst as the standard stimulus in a three-interval forcedchoice paradigm. Data were characterized by significant differences between the performances of the 4-, 6-, and 8-year-olds and those of the adults. Acquisition of adult-like discrimination performance was demonstrated between the ages of 8 and 10 years.
