Although it is shown that attention plays an important role both in the onset and in the regulation of emotions in people without disabilities there is no information about how attention is related to emotions in people with severe or profound intellectual disability (ID). Therefore, in our study, we investigated the role of attention in the onset…

We delineated the achievement of early speech-language milestones in 15 young children with Rett syndrome ("MECP2" positive) in the first two years of life using retrospective video analysis. By contrast to the commonly accepted concept that these children are normal in the pre-regression period, we found markedly atypical development of…

In this study, the effectiveness of instruction and video feedback on response prompting and trainer behavior of direct-care staff during one-to-one training with five children with severe intellectual disability was assessed. During instruction, written information and verbal instruction were given concerning correct and incorrect trainer…

We studied the gestures used by children with classic Rett syndrome (RTT) to provide evidence as to how this essential aspect of communicative functions develops. Seven participants with RTT were longitudinally observed between 9 and 18 months of life. The gestures used by these participants were transcribed and coded from a retrospective analysis…

One of the challenges of developmental psychopathology is to determine whether identifiable pathways to developmental disorders exist in the first months or years of life. Early identification of such disorders poses a similar challenge for clinical services. Using data from a large contemporary birth cohort, we examined whether psychopathology at…

We evaluated a video prompting procedure to teach adults with developmental disabilities to take a digital photograph and print it using a laptop computer and a printer. Participants were four men with developmental disabilities. Training was conducted at the participants' residential facility. During baseline, participants were told to take a…

To establish which social interactive behaviours predict later psychiatric diagnosis, we examined 180 videos of a parent-infant interaction when children were aged one year, from within the Avon Longitudinal Study of Parents and Children (ALSPAC) cohort. Sixty of the videos involved infants who were later diagnosed with a psychiatric disorder at…

Video modeling with other as model (VMO) is a more practical method for implementing video-based modeling techniques, such as video self-modeling, which requires significantly more editing. Despite this, identification of contextual factors such as participant characteristics and targeted outcomes that moderate the effectiveness of VMO has not…

In the current study, behavior skills training (BST) is compared to a computer based training package for teaching discrete trial instruction to staff, teaching an adult with autism. The computer based training package consisted of instructions, video modeling and feedback. BST consisted of instructions, modeling, rehearsal and feedback. Following…

Technology-aided programs for assisting communication and leisure engagement were assessed in single-case studies involving two men with amyotrophic lateral sclerosis (ALS). Study I involved a 51-year-old man with a virtually total loss of his motor repertoire and assessed a technology-aided program aimed at enabling him to (a) write and send out…

Identifying emotions in people with severe and profound intellectual disabilities is a difficult challenge. Since self-reports are not available, behaviour is the most used source of information. Given the limitations and caveats associated with using behaviour as the sole source of information about their emotions, it is important to supplement…

Rett syndrome (RTT) is a developmental disorder characterized by regression of purposeful hand skills and spoken language, although some affected children retain some ability to speech. We assessed the communicative abilities of five young girls, who were later diagnosed with the preserved speech variant of RTT, during the pre-regression period…

A twin study is an excellent means of assessing the contribution of heritability to motor behaviour. We present a movement video-analysis of a monozygotic twins pair with a motor repertoire which is almost totally constituted by persistent and subcontinuous motor stereotypies. Purpose: The specific aim of this study is to verify the heritable…

The effectiveness of a multi-component computer based training package that consisted of competency based instructions, video modeling, and two forms of feedback was evaluated in terms of treatment integrity of two procedures across four staff. Treatment integrity in completing critical steps of discrete-trial and backward chaining procedures were…

The teaching of imitation skills is often the first step in interventions for young learners with intellectual disabilities. The main goal of this study was to determine the smallest detectable difference (SDD) at 95% confidence of the Preschool Imitation and Praxis Scale (PIPS) in preschoolers with intellectual disabilities. Two raters…
