Background: Individuals with Prader-Willi syndrome (PWS) are at increased risk for mental health and behaviour problems, such as skin-picking and compulsive behaviours. Prevalence and functional assessment of skin-picking, and its association with compulsive behaviour and self-injury, were investigated in a large group of individuals with PWS (n =…

Background: The ability of descriptive assessments to differentiate functions of problem behaviours might be increased by systematically sampling natural contexts characterized by different establishing operations. This study evaluated the stability of such characteristics, and variability in challenging behaviour, for three school contexts.…

Bioinformatics has emerged as an important discipline within the biological sciences that allows scientists to decipher and manage the vast quantities of data (such as genome sequences) that are now available. Consequently, there is an obvious need to provide graduates in biosciences with generic, transferable skills in bioinformatics. We present…

Functional assessment procedures have proven useful for developing effective individualized interventions for a wide variety of populations and behavioral concerns. However, fewer studies have been conducted with preschool students who exhibit high incidence problem behaviors. The current study includes data from comprehensive functional…

The process of functional assessment has emerged as an essential component for intervention development. Applications across divergent types of problem behavior, however, remain limited. This study evaluated the applicability of this promising approach to students with selective mutism. Two middle school students served as participants. The…

Rumination is a serious problem demonstrated by some people with developmental disabilities, but previous research has not included a functional analysis and has rarely compared intervention methods during the assessment process. We conducted functional analyses with 2 children who displayed postmeal rumination and subsequently evaluated a…

Functional analysis test conditions typically manipulate a single antecedent variable and an associated consequence to better isolate response reinforcer relations. In some instances no problem behavior is observed, perhaps representing a false-negative finding. The present study evaluated one approach to assess potentially false-negative findings…

This article describes the procedures employed to develop a generic scoring rubric to evaluate students? responses on functional behavior assessment cases. The generic rubric was then used to develop case specific scoring rubrics. The components of the generic scoring rubric, its effectiveness to reliably score students? responses across cases,…

Background: Kinship theory suggests that genomic imprinting could account for phenotypic behaviors that increase (in the case of Angelman syndrome) or decrease (for Prader-Willi syndrome) the drive to access social resources (adult contact) depending on the imprinting parent-of-origin. Difficult to manage behaviors, such as aggression that is…

This paper introduces educators to CHARGE syndrome (CS), a multiple anomaly developmental syndrome that is usually accompanied by some degree of hearing and visual impairment. We describe the defining medical characteristics of the syndrome, and following this, outline the behavioral features commonly seen in individuals with CS. Throughout, we…

Despite its avowed goal of understanding individual behavior, the field of behavior analysis has largely ignored the determinants of consistent differences in level of performance among individuals. The present article discusses major findings in the study of individual differences in intelligence from the conceptual framework of a functional…

There may have been a time when we in Kenya considered the use or abuse of drugs as a problem relating only to Western world. Today it has become an African problem to the extent that a month hardly passes without media reports on large quantities of drugs having been intercepted in a number of African cities and towns. The results of the study…

The purpose of the current study was to replicate the use of parents as therapists for experimental functional analyses of inappropriate mealtime behavior with multiple participants while measuring procedural integrity. Clear functions were identified, and high percentages of procedural integrity were obtained. (Contains 1 figure.)

Abuse, neglect, or both often result in removing children from their homes and placing them in foster care. As a result of these experiences, many children learn unhealthy behaviors. These "behavioral challenges" often lead to a cycle of multiple placement disruptions and progressively more restrictive placements. The philosophy,…

This study determined the effectiveness of noncontingent escape access to self-reinforcement, as a student-directed intervention. Three students successfully used a break card to systematically decrease inappropriate behavior maintained by negative reinforcement while increasing task engagement. In addition, teachers completed an Intervention…
