This study examined the relationship between parent's feeding practices and the feeding behavior of toddlers and preschool-age children with (n = 19) or without (n = 26) persistent feeding difficulties. Specifically, patterns of parent-child interaction were assessed during standardized family mealtime observations in the clinic. Parents also kept observational records of their children's mealtime behavior at home and rated the degree of difficulty they experienced in feeding their child during each meal on a daily basis. Observational results showed that feedingdisordered children engaged in higher levels of disruptive mealtime behavior (food refusal, noncompliance, complaining, oppositional behavior, and playing with food) and lower levels of chewing during mealtime. There were several significant age effects, with younger children (under age 3) engaging in more vomiting and less aversive demanding and verbalizations. Parents of feeding-disordered children were more negative and coercive in their feeding practices and engaged in higher levels of aversive instruction giving, aversive prompting, and negative eating-related comments. There were several significant associations between coercive parental behaviors and children's food refusal and noncompliance in the sample as a whole. Measures of children's disruptiveness at mealtimes in the clinic were significantly correlated with measures of mealtime behavior in the home.

The limited communicative abilities of young children with autism and developmental disabilities may be enhanced by augmentative communication systems such as the Picture Exchange Communication System (PECS). Both children and adults can learn to use PECS, but research is inconsistent in establishing the degree to which PECS training transfers reliably from the training setting to other settings, for example, regular classrooms, and home. Three 5–6 year-old children, diagnosed as autistic and/or developmentally disabled, were given 1:1 PECS training at school, structured to enhance generalisation and transfer. Concurrent observations were made in their regular classroom and at home to probe the extent of generalisation. All three acquired the ability to request a preferred object or activity by exchanging a picture symbol with a communicative partner. In tests of transfer and generalisation, a multiple-baseline across subjects design showed no use of PECS symbols either in the classroom or at home prior to training, with spontaneous initiations of picture exchange (transfer) occurring to a slight to moderate degree in the classroom and to a slight degree at home. Even with PECS training structured to enhance transfer, functionally significant degrees of generalisation of training may be difficult to achieve, and cannot be assumed to occur.

Four adult, moderately intellectually handicapped persons who lived independently in the community were trained in safe exiting from their bedrooms in the event of fire. Baseline levels of competence were low, typically less than 20% of steps correct. Training was introduced to each trainee following a multiple probe across subjects design. Failures to complete a step were followed by video prompting in which the trainee watched a video of a model (an intellectually handicapped male) demonstrate the correct performance of the step. Acquisition required at most 10 sessions, the skills transferred to another residence and to the trainee's bedroom, and were maintained at 5 weeks.
