Vocabulary checklists completed by caregivers are a common way of measuring children's vocabulary knowledge. We provide evidence from checklist data from 31 children with and without autism spectrum disorder. When asked to report twice about whether or not their child produces a particular word, caregivers are largely consistent in their…

Mind-mindedness (MM), the parent's propensity to treat their young child as an individual with a mind of their own, has repeatedly been found to be positively associated with subsequent child development outcomes. In the current Swedish study, the first aim was to investigate the main features of MM in this cultural context and the second aim was…

Previous research has shown that the quality of mother-child interactions between pre-term children and their mothers tends to be poorer than that of full-term children and their mothers (Forcada-Guex, Pierrehumbert, Borghini, Moessinger & Muller-Nix, 2006). Mothers of pre-term children are less responsive and more intrusive in interactions…

Infants from low-socioeconomic status (SES) households hear a projected 30 million fewer words than their higher-SES peers. In a recent study, Hirsh-Pasek et al. (Psychological Science, 2015; 26: 1071) found that in a low-income sample, fluency and connectedness in exchanges between caregivers and toddlers predicted child language a year later…

Purpose: To extend our knowledge about factors influencing early vocabulary development for infants with cochlear implants (CIs), we investigated the impact of positive parenting behaviors (PPBs) from the Indicator of Parent Child Interaction, used in parent-child interactions during everyday activities. Method: Implantation age for the sample…

Previous research indicates that infant-directed speech (IDS) is usually slower than adult-directed speech (ADS) and mothers prefer placing a focused word in isolation or utterance-final position in (English) IDS, which may benefit word learning. This study investigated the speaking rate and word position of IDS in two typologically-distinct…

Deaf children with cochlear implants (CIs) need a supportive family environment to facilitate language development. The present study was designed to assess the effects of parent training (PT) on enhancing children's communication development. The PT was based on the "It Takes Two to Talk" model, with specific adaptations for families of…

This study reports child and family outcomes from a community-based, quasi-experimental pilot trial of "Project ImPACT for Toddlers" that is a parent-mediated, naturalistic, developmental behavioral intervention for children with or at-risk for autism spectrum disorder developed through a research-community partnership. Community early…

This study reports child and family outcomes from a community-based, quasi-experimental pilot trial of "Project ImPACT for Toddlers" ("PI[superscript T]"). "PI[superscript T]" is a parent-mediated, naturalistic, developmental behavioral intervention for children with or at-risk for autism spectrum disorder developed…

Lexical development of bilingual children is influenced by a number of input factors. In the present study, early lexical skills of 25-month old children growing up with Turkish and German were assessed. Parents of 92 children filled out a newly developed list for productive Turkish vocabulary, as well as a vocabulary list for German. A parental…

Children with developmental disabilities (DD) may experience delays in their ability to speak and communicate with their parents, peers, and others. These children often benefit from evidence-based, parent-implemented communication interventions. In the current study, two mothers were trained and coached to use storybook reading techniques and…

Although a bilingual advantage has been reported for various measures of cognitive control, most previous studies have looked at a limited range of cognitive control measures. Furthermore, they typically leave unaddressed whether positive effects of bilingualism hold for all bilinguals or whether these are modulated by differences in bilingual…

Developmental approaches to autism treatment aim to establish strong interpersonal relationships through joint play. These approaches have emerging empirical support; however, there is a need for further research documenting the procedures and demonstrating their effectiveness. This pilot study evaluated changes in parent behavior and child autism…

Purpose: This experiment examined English- or Spanish-learning preverbal (8-9 months, n = 32) and postverbal (12-14 months, n = 40) infants' learning of word-action pairings prior to and after the transition to verb comprehension and its relation to naturally learned vocabulary. Method: Infants of both verbal levels were first habituated to 2…

Background: Children with sex chromosome trisomies (SCT) frequently show problems in language development. However, a clear description of the communicative patterns of these children is still lacking. Aims: To describe the first stages of language development in children with SCT in comparison with those in typically developing (TD) children. The…
