Prefrontal synthesis (PFS) is a component of constructive imagination. It is defined as the process of mentally juxtaposing objects into novel combinations. For example, to comprehend the instruction "put the cat under the dog and above the monkey," it is necessary to use PFS in order to correctly determine the spatial arrangement of the…

Metacognition plays an important role in the development of young children. Recent studies have found that metacognition and executive function are independent but closely related. In this study, 55 children aged 4-5 years were selected as subjects, and a short-term longitudinal design was used to analyze the relationships among metacognition,…

Autistic children have difficulties in adapting their language for particular listeners and contexts. We asked whether these difficulties are more prominent when children are required to be cognitively flexible, when changing how they have previously referred to a particular object. We compared autistic (N = 30) with neuro-typical 5- to…

The present study aims to examine the Executive Function (EF) skills of preschool-aged children who are deaf and hard of hearing (DHH), and explore the variables related to their EF skills. Thirty preschoolers who were DHH and an additional 35 preschoolers with typical hearing were recruited. All DHH use spoken language as their communication…

Purpose: This study examined the relationship between language and planning, a higher order executive function skill, in children with specific language impairment (SLI) and typically developing (TD) children. We hypothesized differences between groups in planning performance and in the role of verbal mediation during planning. Method: Thirty-one…

This study tests the role of verbal mediation during theory of mind processing in autism spectrum disorder (ASD). Adolescents with ASD or typical development completed a false belief task while simultaneously performing a verbal or nonverbal load task. There was no group difference in false belief "accuracy;" however, under verbal load,…

The development of beginning decoding and encoding skills is influenced by linguistic skills as well as executive functions (EFs). These higher-level cognitive processes include working memory, inhibition, and cognitive flexibility, and individual differences in these EFs have been shown to contribute to early academic learning. The present study…

Many young people with autism spectrum disorder display 'challenging behaviours', characterised by externalising behaviour and self-injurious behaviours. These behaviours can have a negative impact on a young person's well-being, family environment and educational achievement. However, the development of effective interventions requires greater…

Bilingual preschoolers often perform better than monolingual children on false-belief understanding. It has been hypothesized that this is due to their enhanced executive function skills, although this relationship has rarely been tested or supported. The current longitudinal study tested whether metalinguistic awareness was responsible for this…

The complicated cognitive processes involved in natural (primary) bilingualism lead to significant cognitive development. Executive functions as a fundamental component of human cognition are deemed to be affected by language learning. To date, a large number of studies have investigated how natural (primary) bilingualism influences executive…

To address the needs of the high population of students with learning disabilities at their school, the author and a colleague created an inclusion science class that focuses on active, hands-on science. The course prepares students of various learning abilities for the state-mandated end-of-course biology assessment. Many of their students have…

Hala, Brown, McKay, and San Juan (2013) found that children as young as 2.5 years of age demonstrated high levels of accuracy when asked to recall whether they or the experimenter had carried out a particular action. In the research reported here, we examined the relation of early-emerging source monitoring to executive function abilities.…

The current study tested 2 models of inhibition in 45 children with language impairment and 45 children with normally developing language; children were aged 7 to 12 years. Of interest was whether a model of inhibition as a mental-control process (i.e., executive function) or as a mental resource would more accurately reflect the relations among…

The present study explored the relation between language control and nonverbal cognitive control in different bilingual populations. We compared monolinguals, Dutch-French unbalanced bilinguals, balanced bilinguals, and interpreters on the Simon task (Simon & Rudell, 1967) and the Attention Network Test (ANT; Fan, McCandliss, Sommer, Raz,…
