Precursor behaviors are innocuous behaviors that reliably precede the occurrence of problem behavior. Intervention efforts applied to precursors might prevent the occurrence of severe problem behavior. We examined the relationship between precursor behavior and problem behavior in three individuals with developmental disabilities. First, a descriptive (correlational) assessment focusing on tran...

any sort of punishment could motivate any sort of prosocial behavior. In reality, punishment must conform itself to the circumscribed ability of organisms to learn. There is one species with a substantially expanded learning abilities: humans. It is no accident, therefore, that we also exhibit a uniquely flexible and productive prosocial behavior. To the extent that punishment (and also recipro...

UNLABELLED BACKGROUND Older adults experience activity and participation limitations that are associated with ageing. Activity and participation limitations affect an older adult's ability to engage in meaningful daily activities and valued life roles. Occupational therapists provide interventions to reduce such limitations and monitor client change to ensure that interventions are effective...

For functional neuroimaging studies of stuttering, two challenges are (1) the elicitation of naturally stuttered versus fluent speech and (2) the separation of activation associated with abnormal motor execution from activation that reflects the cognitive substrates of stuttering. This paper reports on a proof-of-concept study, in which a single-subject approach was applied to address these two...

This study evaluated a variation of functional assessment methodology, the structured descriptive assessment (SDA). The SDA is conducted in an individual's natural environment and involves systematically manipulating antecedent variables while leaving consequences free to vary. Results were evaluated by comparing the results of an SDA with results obtained from an analogue functional analysis w...

The results obtained from two consecutive functional analyses conducted with a 6-year-old child with autism are described. In the initial functional analysis, the highest rates of problem behavior occurred in the play condition. In that condition, the delivery of attention appeared to occasion problem behaviors. A second functional analysis was conducted wherein an escape from attention conditi...

In this article we would like to present some recent applications of the B formal method to the development of safety critical systems, namely platform screen door controllers. These SIL3/SIL4 compliant systems have their functional specification based on a formal model. This model has been proved, guaranteeing a correct by construction behaviour of the system in absence of failure of its compo...

OBJECTIVE Subjects with functional dyspepsia (FD) in most previous studies have been confined to those who sought medical consultation. The generalizability of results from these studies to individuals with FD who do not seek medical consultation is limited. This study examined 1) differences in perceptual and behavioral characteristics between "nonconsulters" and "consulters" with FD and 2) th...

We evaluated the utility of an assessment for identifying tasks for the functional analysis demand condition with 4 individuals who had been diagnosed with autism. During the demand assessment, a therapist presented a variety of tasks, and observers measured problem behavior and compliance to identify demands associated with low levels of compliance or high levels of problem behavior (low-proba...

BACKGROUND AND PURPOSE A stroke affects not only the patient but also the spouse. To better support the spouse during the acute phase of stroke, knowledge is needed about his or her experience with the situation. The aim of the present study was to study the well-being of the spouses of stroke patients during the acute state of stroke and to identify factors that may influence their well-being....
