Recommendations for achieving generalized instructional outcomes often overlook the capacity for generative learning. We sought to demonstrate how decontextualized and logically organized instruction would lead to derived and contextually appropriate recombinative generalization and arbitrarily applicable relational responding (AARRing) in…

Background: The purpose of the current study was to examine association between physical activity (PA) of parents of children with developmental disabilities and theory of planned behaviour-related variables. Methods: A total of 95 participants completed questionnaires that measured the following variables: PA behaviours, action planning,…

The acquisition of skills by individuals with developmental disabilities typically includes the attainment of a certain mastery criterion. We conducted a survey of practitioners who indicated the most commonly used mastery criterion as 80% accuracy across three consecutive sessions. Based on these results, we conducted a series of three…

Background and aims: Children with developmental language disorder (DLD) are at risk of difficulties in their friendships and peer relations. The present review explores how research directly involving children with DLD can inform our understanding of peer relations in this group, and how research insights may change according to the nature of…

The research studies presented in this special issue rest on two assumptions: firstly, that limitations in verbal short-term memory and verbal working memory (vSTM/WM) capacity are likely to be related to impairments in syntax, and secondly that this relationship is likely to be causal, with impairments in vSTM/WM causing impairments in syntax. In…

Objective: This study aims to delineate the characteristics of severe self-injurious behaviors (SIB) in a cohort of children with autism and unspecified intellectual developmental disorder (UIDD) (intellectual disability) and examine potential risk factors for developing SIB. Methods: A retrospective chart review studied characteristics of severe…

The relevance of the quality of parent-child interactions for child development has long been established. Nevertheless, research on beliefs about maternal sensitivity is still scarce, to an even greater extent in the context of child disability. This inquiry aimed to describe beliefs about sensitive parenting among mothers of children with…

Cultures could influence parents in the way they perceive adverse situations and in how external factors influence resilience, which in turn, may differentially affect the quality of life of a child. The present study aimed to examine the associations between different dimensions of parental resilience and the quality of life of children in…

The aim of this meta-analysis was to investigate factors associated with resilience in familial caregivers of children with developmental disabilities. The protocol was registered in the PROSPERO database, with the registration number CRD42018105180. Several electronic databases were searched for studies. A random-effects meta-analysis was…

Background: Raising a child with developmental disorder is often related to higher stress levels for both mothers and fathers. The aim of the present study was to investigate relationships between resilience, family hardiness, life satisfaction and parental stress among parents of children with and without disabilities. Method: Twenty-eight pairs…

Deficits in numerical magnitude perception characterize the mathematics learning disability developmental dyscalculia (DD), but recent studies suggest the relation stems from inhibitory control demands from incongruent visual cues in the nonsymbolic number comparison task. This study investigated the relation among magnitude perception during…

Background: Children with developmental language disorder (DLD) are at higher risk of poorer mental health compared with children without DLD. There are, however, considerable individual differences that need to be interpreted, including the identification of protective factors. Aims: Pathways from the early language and communication environment…

Purpose: The storage-only deficit and joint mechanism deficit hypotheses are 2 possible explanations of the verbal working memory (vWM) storage capacity limitation of school-age children with developmental language disorder (DLD). We assessed the merits of each hypothesis in a large group of children with DLD and a group of same-age typically…

The causal role of speed of processing (SOP) in developmental language disorder (DLD) is unclear given that SOP has been implicated in other neurodevelopmental disorders such as attention-deficit/hyperactivity disorder. This study investigated associations between SOP, language, and inattention/hyperactivity in a U.K. epidemiological cohort…

Purpose: Immature auditory processing has been proposed to underlie language impairments in children with developmental language disorder (DLD; also known as "specific language impairment"). Using newly available normative auditory evoked potential (AEP) waveforms, we estimated AEP maturity in individual children with DLD and explored…
