We observed three children with autism spectrum disorder during structured play dates in which play partners displayed interest or disinterest in the toys with which they were playing. We then taught subjects to identify play partners’ preferences and to make appropriate toy offers using a multiple‐exemplar training package consisting of rules, midplay preference questions, prompting, and praise with observed generalization across untrained partners.

We evaluated the effects of behavioral skills training in the home for teaching children with autism to abstain from going with strangers and immediately inform a familiar adult of the stranger’s attempt to lure them in the natural environment. All participants learned to respond correctly to lures in the home and demonstrated concomitant changes in untrained natural settings. In situ training and an added incentive were necessary for 1 participant.

This study used a nonconcurrent multiple baseline across participants design to evaluate the use of rules, role-play, and feedback for teaching 3 children with autism spectrum disorder to tell socially appropriate lies when (a) presented with an undesired gift and (b) someone’s appearance changed in an undesired way. The intervention was effective in teaching use of socially appropriate lies, and generalization to untrained people and gifts or appearances was observed.

Functional analysis has been demonstrated to be an effective method to identify environmental variables that maintain problem behavior. However, there are cases when conducting functional analyses of severe problem behavior may be contraindicated. The current study applied functional analysis procedures to a class of behavior that preceded severe problem behavior (precursor behavior) and evaluated treatments based on the outcomes of the functional analyses of precursor behavior. Responding for all participants was differentiated during the functional analyses, and individualized treatments eliminated precursor behavior. These results suggest that functional analysis of precursor behavior may offer an alternative, indirect method to assess the operant function of severe problem behavior.

Children with autism may not develop safety skills (e.g., help-seeking behaviors) without explicit teaching. One potentially hazardous situation is when a child with autism becomes separated from caregivers in a retail establishment or other public setting. The purpose of this study was to evaluate a treatment package (rules, role playing, and praise) delivered in the natural environment for teaching 3 boys with autism to seek assistance from store employees when they became lost. Treatment was effective, and help-seeking behaviors generalized to untrained stores for all participants.

Evaluating effects of utilizing parents as therapists for treating behavior problems has become increasingly important in the dissemination and practice of applied behavior analysis. However, home-based parent training approaches have been underused in treating feeding problems. In this study, mothers were trained to implement differential reinforcement of alternative behavior (DRA) combined with non-removal of the spoon and demand fading for the treatment of their childrens’ food selectivity. The procedures were highly effective and generalization to untargeted foods was observed. Parent procedural integrity and parent collected interobserver agreement (IOA) data remain high throughout the study. This study also demonstrated an effective method for systematically decreasing reinforcement magnitude and schedules in an effort to mimic traditional reinforcer delivery such as intermittently providing a dessert at the end of the meal. Finally, this study successfully increased a demand fading ratio of 50–150% without noticeable side effects.

Bruxism, forceful grinding of one’s teeth together, can produce destructive outcomes such as wear on the teeth and damaged gums and bone structures. The current study implemented a multicomponent intervention that consisted of vocal and physical cues to decrease rates of bruxism. A partial component analysis suggested that the vocal cue was only effective at decreasing levels of bruxism when paired with a simultaneous physical cue.
