In this paper I discuss (a) three steps in the development of establishing operation (EO) terminology, (b) my early neglect of its possible relevance to applied behavior analysis, (c) the importance of functional analysis methodology for increasing awareness of EO issues, and (d) three comprehensive reviews that clarify the role of EOs in applied work. I then review and further analyze seven topics that require further clarification or that have been raised since my 1982 and 1993 articles: the EO evocative effect, deprivation and satiation, problem behavior maintained by attention, decreasing behavior evoked by a transitive conditioned establishing operation, EOs in the context of escape and avoidance, academic demand, and decreasing behavior evoked by a reflexive conditioned establishing operation.  相似文献

This article provides commentary on research published in the special section of the Journal of Applied Behavior Analysis devoted to establishing operations (EOs). Three major themes are highlighted: (a) identification of the influence of EOs on behavior in applied settings, (b) the use of EO manipulation as an assessment tool, and (c) the development of interventions based on the alteration of EO influences. Methodological issues pertaining to research on EOs are addressed, and suggestions for future investigation are provided.  相似文献

We conducted functional analyses of aberrant behavior with 4 children with developmental disabilities. We then implemented functional communication training (FCT) by using different mands across two contexts, one in which the establishing operation (EO) that was relevant to the function of aberrant behavior was present and one in which the EO that was relevant to the function of aberrant behavior was absent. The mand used in the EO-present context served the same function as aberrant behavior, and the mand used in the EO-absent context served a different function than the one identified via the functional analysis. In addition, a free-play (control) condition was conducted for all children. Increases in relevant manding were observed in the EO-present context for 3 of the 4 participants. Decreases in aberrant behavior were achieved by the end of the treatment analysis for all 4 participants. Irrelevant mands were rarely observed in the EO-absent context for 3 of the 4 participants. Evaluating the effectiveness of FCT across different contexts allowed a further analysis of manding when the establishing operations were present or absent. The contributions of this study to the understanding of functional equivalence are also discussed.  相似文献

Researchers have demonstrated that both deprivation and satiation can affect the outcome of preference assessments for food. In the current study, paired-stimulus preference assessments for tangible items were conducted under three conditions: control, deprivation, and satiation. Three persons with developmental disabilities and 3 typically developing preschool children served as participants. The results demonstrated that deprivation and satiation influenced the outcome of preference assessments of leisure items or toys.  相似文献

The influence of antecedent events on behavior disorders has been relatively understudied by applied behavior analysts. This lack of research may be due to a focus on consequences as determinants of behavior and a historical disagreement on a conceptual framework for describing and interpreting antecedent variables. We suggest that antecedent influences can be described using terms derived from basic behavioral principles and that their functional properties can be adequately interpreted as discriminative and establishing operations. A set of studies on assessment and treatment of behavior disorders was selected for review based on their relevance to the topic of antecedent events. These studies were categorized as focusing on assessment of antecedent events, antecedent treatments for behavior disorders maintained by either positive or negative reinforcement, and special cases of antecedent events in behavior disorders. Some directions for future research on antecedent influences in the analysis and treatment of behavior disorders are discussed.  相似文献

Preference assessments were conducted for 4 individuals with developmental disabilities across conditions of (a) control, allowing equal access to all stimuli prior to the preference assessment; (b) deprivation, allowing no access to one stimulus for 48 hr prior to the assessment; and (c) satiation, allowing free access to one stimulus for 10 min immediately prior to the assessment. Deprivation resulted in increased preference, whereas satiation resulted in decreased preference compared to control conditions.  相似文献

We conducted reinforcer assessments for 3 boys with a diagnosis of attention deficit hyperactivity disorder who alternately received either placebo or previously prescribed methylphenidate. Our purpose was to evaluate whether methylphenidate altered the relative reinforcing effectiveness of various stimuli that are often used in classroom-based behavioral treatment programs (e.g., activities, tangible items). Results showed clear differences for some stimuli between reinforcer assessments conducted when participants had received methylphenidate compared to placebo. Results suggest that methylphenidate might act as an establishing operation for some common classroom reinforcers. Implications for the development and evaluation of behavioral treatments are discussed.  相似文献

Recent research findings (DeRosa, Fisher, & Steege, 2015 ) suggest that minimizing exposure to the establishing operation (EO) for destructive behavior when differential reinforcement interventions like functional communication training (FCT) are introduced may produce more immediate reductions in destructive behavior and prevent or mitigate extinction bursts. We directly tested this hypothesis by introducing FCT with extinction in two conditions, one with limited exposure to the EO (limited EO) and one with more extended exposure to the EO (extended EO) using a combined reversal and multielement design. Results showed that the limited‐EO condition rapidly reduced destructive behavior to low levels during every application, whereas the extended‐EO condition produced an extinction burst in five of six applications. We discuss these findings in relation to the effects of EO exposure on the beneficial and untoward effects of differential reinforcement interventions.  相似文献

In the present investigation, a functional analysis of the disruptive behavior of a 18-year-old man who had been diagnosed with attention deficit hyperactivity disorder and moderate mental retardation was conducted, both when he was taking methylphenidate and when he was not taking the medication. The results of this functional analysis demonstrated that the participant's disruptive behaviors were reinforced by access to attention only when he was not taking methylphenidate.  相似文献

Self-injurious behavior (SIB) can be maintained through negative reinforcement when, in the context of training or task requirements, it produces escape as a consequence. Several studies have demonstrated methods for identifying and treating SIB maintained by negative reinforcement; however, few analyses of the establishing operations associated with demand situations have been conducted. The current series of studies illustrates a method for identifying some establishing operations for escape by systematically altering certain dimensions of the demand context while maintaining an escape contingency for SIB. Dimensions assessed in these studies included task novelty, duration of instructional sessions, and rate of task presentation. Data indicate that these variables can have establishing properties for behavior maintained by escape. Implications of the results are discussed, as are potential refinements and extensions of the assessment procedures.  相似文献

The effect of presession attention on the later occurrence of problem behavior was examined with elementary-school children with a range of disabilities. Results of analogue functional analyses suggested an escape function, an attention function, or both. Following the analogue functional analyses, the effects of two antecedent conditions (10-min ignore vs. 10-min attention) were compared on problem behavior in subsequent test conditions. For participants who displayed attention-maintained problem behavior, the test condition involved contingent attention for problem behavior. For participants who displayed escape-maintained problem behavior, the test condition involved contingent escape for problem behavior. Results indicated that participants who displayed attention-maintained problem behavior displayed less problem behavior following presession exposure to attention than when ignored. No such effect was found for presession attention on escape-maintained problem behavior. We discuss matching antecedent-based interventions to the results of functional analysis.  相似文献

Establishing operations (EO) influence operant responding by altering the reinforcing effectiveness of consequences (reinforcer establishing or abolishing effect) and changing the frequency of behavior that has been reinforced by those consequences in the past (evocative or abative effect) (Michael, 1982 , 1993 ). In this study we attempted to isolate the evocative and abative effects of an EO for positively reinforced challenging behavior with a person with autism and developmental disabilities. The study consisted of three phases. First, an analogue functional analysis identified attention as maintaining challenging behavior. Second, access to attention was systematically controlled (continuous access versus no access) immediately prior to functional analysis sessions in which the participant received attention on an FR1 schedule. Results of this phase indicated that challenging behavior occurred at higher levels during the functional analysis sessions when access to attention was restricted immediately prior to sessions (i.e., no access appeared to function as an EO). In the third phase, prior access to attention was again controlled as in the second phase of the study, however the participant was then placed on extinction. The results of this final phase seem to indicate that no access to the reinforcer prior to extinction had an evocative effect (produced high levels of responding) whereas access to the reinforcer had an abative effect (produced lower levels of responding) during extinction sessions.

The effects of presession exposure to attention on responding during subsequent assessments of attention as a reinforcer were evaluated across three behavioral assessments. In Experiment 1, a contingent attention assessment condition was preceded by either a noncontingent attention condition (free play) or a contingent escape condition. In Experiment 2, a diverted attention with extinction condition was preceded by either an alone or a free-play condition. In Experiment 3, a two-choice preference assessment was preceded by either 10 min of free play or 10 min of playing alone. In each experiment, the participant responded differentially within the test condition according to the presence or absence of dense schedules of attention immediately prior to that condition. The results of this study show that events occurring immediately prior to an assessment condition can influence behavior within the assessment.  相似文献

A preliminary evaluation of the correspondence between functional analysis outcomes across settings was conducted with 2 children who had been diagnosed with autism and who engaged in challenging behavior. Differences across settings (a therapy room and a classroom) were demonstrated in ABAB reversal designs. Three potential patterns of results that may occur when comparing functional analyses across environments are described, and one possible explanation for the occurrence of discrepancies between environments (differing learning histories within separate environments) is offered.  相似文献

Previous studies have shown that presession attention for problem behavior can serve as an abolishing operation when attention functions as a positive reinforcer. In the current study, we show that the stereotypy of a child with severe disabilities was undifferentiated during standard analogue functional analysis conditions. However, when noncontingent presession attention was provided, stereotypy occurred for social attention as a positive reinforcer, suggesting that the antecedent manipulation functioned as an establishing operation.  相似文献

A multiple baseline design was used to evaluate the effects of adding condiments on the consumption of previously rejected foods (vegetables). Adding condiments produced increased food acceptance across three food items. Data are discussed in relation to conditioned food preferences and establishing operations.  相似文献

Establishing operations can alter problem behaviors by changing the momentary value of reinforcers associated with those problem behaviors. If establishing operations (EOs) precede the presentation of discriminative stimuli (SDs) for problem behaviors, it may be possible to introduce neutralizing routines that both reduce the value of reinforcers associated with problem behaviors and decrease the occurrence of problem behaviors. The present study examined this logic with 3 adolescents with severe intellectual disabilities. Initial functional analyses indicated that problem behaviors were motivated by either escape or tangible items. Functional assessment interviews identified possible establishing operations that were associated with the occurrence of problem behavior and indicated that these establishing operations occurred over 1 hr before presentation of the SD for problem behaviors. We used an alternating treatments design to examine problem behaviors during instruction under four conditions: EO + SD, SD only, EO only, and neither SD nor EO. For all 3 participants, problem behaviors occurred almost exclusively during the EO + SD condition. A further analysis compared the EO + SD condition when neutralizing routines were embedded between the EO and the SD. Results from an ABAB reversal design supported the effectiveness of neutralizing routines to reduce these problem behaviors. Applied and theoretical implications are discussed.  相似文献
