A Blueprint for Schoolwide Positive Behavior Support: Implementation of Three Components

This article provides a case study (focus on an eighth-grader with autism) within a case study (focus on an urban middle school) in terms of the implementation of positive behavior support (PBS). Information is provided on the characteristics of three key components of schoolwide PBS-universal support, group support, and individual support. For each component, information is presented on policy, assessment, and intervention in terms of an evolving approach to schoolwide PBS with descriptions of how the components were implemented at the middle school with a particular emphasis on the eighth-grade student. The authors conclude with implications for practice in terms of assessing current resources, providing professional development, and intensifying universal support within urban schools to address some of the complex issues associated with poverty

Receptive training of adjectival inflections in mental retardates

A generalized discrimination of /er/ and /est/ suffixes as labels for stimuli exemplifying comparative or superlative relationships was established in three institutionalized retardates through differential reinforcement. The subjects were first taught correct pointing in response to opposite adjectives (e.g., “big—small”) presented as labels for simple visual stimuli, and then taught each of the comparatives, or each of the superlatives possible for those opposites (e.g., “big—bigger” and “small—smaller”, or “big—biggest” and “small—smallest”). As training proceeded, novel combinations of the training stimuli were presented as unreinforced probes to display any developing generalization of the training. As training of comparative discrimination proceeded, correct pointing response to comparative probes was high, but correct response to superlative probes was low. When training of superlative discriminations replaced training of comparatives, correct response to superlative probes increased, and correct response to comparative probes remained high

An analysis of individual differences in generalization between receptive and productive language in retarded children

Retarded subjects were taught generative pluralization rules concurrently in both the receptive and productive modalities of language. Receptive training established correct pointing to either one or a pair of objects, in response to a spoken singular or plural label of the object(s); productive training established correct spoken labels of one or a pair of objects presented visually. However, these pluralization rules were established in each modality only for a specific class of plurals: those ending in -s for one modality, those ending in -es for the other modality. This training was successful in establishing generative, or rule-governed behaviors, such that untrained examples of singulars and plurals were usually responded to correctly. Nevertheless, despite this concurrent, generative behavior, probes revealed little generalization between modalities: three of four subjects did not generalize clearly from receptive training with one class of plurals to correct productive use of that class, nor did they generalize from productive training of the other class of plurals to correct receptive response to that class. The fourth subject, however, did show strong generalization of both these types. It was concluded that automatic generalization between receptive and productive language is not necessarily an inevitable result of language training in such subjects, and therefore may require explicit, if temporary, programming, such as by direct reinforcement

Development of syntax in a retarded girl using procedures of imitation, reinforcement, and modelling

Three experiments demonstrated the development and generalized use of a singular and plural declarative sentence in a child initially lacking sentence form responses. In each experiment, an adult(s) served as a language model(s), and consequences (sweets) were provided for imitation of the model. During training trials, an item(s) was displayed first to the model(s) then to the subject; these displays were accompanied by requests to label the item(s). Generalization was assessed by a number of probe trials that were periodically interspersed among training trials. During these trials, the subject was requested to label the displayed item(s) without any preceding labelling response from the model. Using these procedures, generalized use of a singular sentence (“That is one—”) resulted in Experiment I, and generalized use of a plural sentence (“These are two—”) resulted in Experiment II. In Experiment III, two models (a singular and a plural sentence model) were made available to the subject but imitation of only one model was reinforced during any one condition. Results indicated the subject labelled probe (generalization) items with the same sentence form that was modelled and reinforced during training trials

An experimental analysis of linguistic development: the productive use of the plural morpheme

Operant conditioning procedures were used to establish a generative use of the plural morpheme in the speech of a severely retarded girl. During training trials, reinforcement was presented contingent upon correct imitation of singular and plural verbalizations by the experimenter, in response to objects presented to the subject singly and in pairs. A generative productive plural usage resulted, the girl correctly labeling new objects in the singular or plural without further direct training relevant to those objects. After establishing the singular/plural usage, the contingencies were reversed (reinforcement of plural responses to single objects, and vice-versa). This produced a corresponding reversal of response by the child. The original usage was then recovered by returning to the previous contingencies. A second experiment analyzed certain error responses occurring during the first experiment, and further probed the generative nature of the subject's plural usage. It was found that errors were somewhat more likely to occur in the pluralization of words ending in vowels than of words ending in consonants. Furthermore, several words whose plurals had been learned according to the reversed plural rule, when examined later during reinforcement of normal plural usage, were found then to exemplify the normal rule being reinforced, yet without direct training

Control of tantrum behavior by operant techniques during experimental verbal training

A technique of controlling undesirable or disruptive behavior during an ongoing program of verbal training with a retardate is described. The technique required that the stimulus materials of the verbal training program be graded according to difficulty, i.e., in terms of the length and complexity of the stimulus materials. (This resulted in an initial grading of the stimulus materials into different levels of probability of reinforcement.) Changes by the experimenter from high-difficulty to low-difficulty stimuli for two trials contingent upon disruptive behavior increased the rate of that behavior; changes from low-difficulty to high-difficulty stimuli for two trials contingent upon disruptive behavior decreased its rate. Thus, contingent alternation of the stimulus materials of the ongoing training program controlled the frequency of undesirable behaviors within the experimental sessions. This technique may comprise an alternative to other procedures which require punishment or timeout from the ongoing program

Improvement of retardates' mealtime behaviors by timeout procedures using multiple baseline techniques

Undesirable mealtime behaviors of a hospital cottage of retardates were reduced by contingent timeout procedures applied by ward personnel successively to one undesirable behavior after another, in a multiple baseline design. In some cases the timeout procedure was to remove the subject from the room until the meal was finished; in other cases (depending on the health of the child and the initial rate of the behavior to be reduced), timeout consisted of a 15-sec removal of the child's meal tray. Undesirable behaviors were defined as stealing, using fingers inappropriately, messy use of utensils, and pigging (eating directly with mouth or eating spilled food). Timeout was applied to these behaviors in that order, and in each case led to a marked and useful reduction in the behavior throughout the group. As these undesirable behaviors were reduced, more appropriate mealtime behaviors emerged: as inappropriate use of fingers declined (under contingent timeout), messy utensil behavior increased; later, as messy utensil behavior declined (under contingent timeout), a defined category of neat utensil behavior increased. Weights of the subjects were monitored steadily throughout the study and showed essentially no change
