INTENTIONALISM AND THE IMAGINABILITY OF THE INVERTED SPECTRUM

Various thought-experiments have been offered as independent support for the possibility of intentionalism-defeating spectrum inversion, but they do not succeed. I refute what I take to be the four best arguments for holding that the thought-experiments do in fact provide such support: the implausible error argument, the symmetry argument, the no-inference argument and the best theory of representation argument. I thus offer a defence of intentionalism against a long-standing objection.     

THE DEVELOPMENT OF CORRECT TOOTHBRUSHING TECHNIQUE IN PRESCHOOL CHILDREN

This study examined the effects of an intensive training program on the toothbrushing skills of three preschool children, using both performance measures and outcome (plaque level) indicators. Toothbrushing was broken into 16 steps that involved actual manipulation of the brush in the mouth. Correct brushing included four criteria: (a) appropriate angle of bristles, (b) appropriate motion of brush, (c) appropriate tooth surface, and (d) minimum duration of brushing. Training included instructions, a three-phase modeling procedure, physical guidance, and reinforcement. Results of a multiple baseline design across subjects showed that the children completed an average of 8.6% of the steps prior to training, as compared with an average of 95.8% of the steps following training. Plaque levels decreased from an average of 58% during baseline to 24.6% after training. Follow-up measures revealed that 86.6% of the steps were maintained. The study demonstrated that the effectiveness of the procedures in teaching very young children a complex motor skill that is essential to their future health.     

THE TREATMENT OF COVERT SELF-INJURY THROUGH CONTINGENCIES ON RESPONSE PRODUCTS

Assessment and treatment of covert self-injurious behavior are complicated because it is difficult to quantify and apply differential consequences to covert responses. In this study, both tangible and social reinforcers were identified using reinforcer assessment methods. These reinforcers were then provided contingent upon the absence of tissue damage identified during physical examinations, resulting in near 100% success in physical assessment checks that was maintained over 10 months.     

SEARCHING FOR ANOTHER EARTH: THE RECENT HISTORY OF THE DISCOVERY OF EXOPLANETS

The discovery of exoplanets is a small part of the array of scientific arguments for and against the existence of extraterrestrial intelligence. Yet the recent stunning achievement of this program of observational astronomy has had a significant effect on scientific opinion and public interest. It also raises some key theological questions. New observing techniques are leading to the discovery of extrasolar planets daily. Earth‐like planets outside of our Solar System can now be identified and in future years explored for signs of life. This article maps the history of these discoveries and highlights some of the theological issues which are important to bring into dialogue with these scientific insights.     

THE APPLICATION OF GENERALIZED CORRECT SOCIAL CONTINGENCIES: AN EVALUATION OF A TRAINING PROGRAM1

Two aides operating a kindergarten-style program for institutionalized mental retardates were trained, using observer feedback, to apply generalized “correct” social contingencies to 10 defined classes of appropriate and inappropriate child behaviors. A multiple baseline design was used to demonstrate, sequentially, the effects of the training procedure upon the attending behavior of each teacher. After withdrawal of feedback, a posttraining follow-up served to assess the durability of training. For both aides, the effect of training was to increase the proportion of appropriate child behaviors attended to, compared with baseline data, and a follow-up over a number of weeks indicated that the effects of training were apparently durable.     

BEHAVIORAL MOMENTUM IN THE TREATMENT OF NONCOMPLIANCE

Behavioral momentum refers to the tendency for behavior to persist following a change in environmental conditions. The greater the rate of reinforcement, the greater the behavioral momentum. The intervention for noncompliance consisted of issuing a sequence of commands with which the subject was very likely to comply (i.e., high-probability commands) immediately prior to issuing a low-probability command. In each of five experiments, the high-probability command sequence resulted in a “momentum” of compliant responding that persisted when a low-probability request was issued. Results showed the antecedent high-probability command sequence increased compliance and decreased compliance latency and task duration. “Momentum-like” effects were shown to be distinct from experimenter attention and to depend on the contiguity between the high-probability command sequence and the low-probability command.     

THE USE OF CONTINGENT-INTERRUPTED MUSIC IN THE TREATMENT OF DISRUPTIVE BUS-RIDING BEHAVIOR

The present study evaluated the efficacy of using contingent-interrupted music in treating the disruptive bus-riding behavior of an 8-year-old profoundly retarded female. Music was played during each bus ride as long as the subject was sitting appropriately, and interrupted contingent upon each response defined as disruptive bus riding, during an ABCDCDCDA design. A significant reduction in disruptive bus riding occurred with each introduction of contingent-interrupted music. The treatment procedure described in this report was easy to administer, produced rapid treatment gains, and showed virtually no regression during an 8-week follow-up period.     

THE EARTH CHARTER AND JOURNEY OF THE UNIVERSE: AN INTEGRATED FRAMEWORK FOR BIODEMOCRACY

The principles of the Earth Charter and the cosmological story of Journey of the Universe provide a unique synergy for rethinking a sustainable future. The Great Story inspires the Great Work of the transformation of the political, social, and economic orders. Such a synergy can contribute to the broadened understanding of sustainability as including economic, ecological, social, and spiritual well‐being. This integrated understanding may be a basis for creating biodemocracies, which will involve long‐term policies, programs, and practices for a planetary future that is not only ethically sustainable, but also sustaining for human energies.     

USE OF NEGATIVE REINFORCEMENT IN THE TREATMENT OF SELF-INJURIOUS BEHAVIOR

Behavioral assessment procedures were used to determine the maintaining conditions of self-injury exhibited by 2 children with severe multiple handicaps. For both children, negative reinforcement (escape from grooming activities) was determined to be the maintaining reinforcer for self-injury (hand/arm biting) within an alternating treatments design. The treatment packages involved the use of negative reinforcement (brief escape from grooming activities) contingent upon a behavior that was incompatible with self-injury (reaching and pressing a microswitch that activated a prerecorded message of “stop”). Treatment was evaluated with a reversal design for 1 child and with a multiple baseline across grooming activities for the 2nd child. The treatment led to a marked decrease in self-injury for both children. At follow-up, high rates of self-injury were reported for the 1st child, but low rates of self-injury and an increase in task-related appropriate behavior were observed for the 2nd child.     

系统脱敏法治疗大鼠恐怖症研究

系统脱敏法对矫治恐怖症的行为障碍具有良好的效果,但是对伴随恐怖症同时存在的生理、生化方面的病态反应的治疗未见报告。实验中采用噪音逐步递增的方法使大鼠慢慢适应,分别测量治疗过程中大鼠惊恐、焦虑性行为、生理行为、生化等方面的变化。结果表明：系统脱敏法不仅有效地矫治大鼠的变态行为,对生物学方面具有明显的疗效,而且可以提高动物的应激适应能力。     

USE OF TEXTURE FADING IN THE TREATMENT OF FOOD SELECTIVITY

Children with feeding disorders often display severe food selectivity. For many of these children, consuming highly textured foods may be aversive or potentially dangerous because of frequent gagging. The purpose of this study was to demonstrate the efficacy of texture fading in the treatment of food selectivity displayed by 4 children. Treatment involved the gradual addition of higher textures based on the results of periodic probes. In addition, food acceptance and swallowing were reinforced, while food refusal and food expulsion were placed on extinction. Results showed that all participants successfully advanced to consumption of age-appropriate texture and volume. The results suggest that texture fading with intermittent probes at higher textures may be an effective method for the treatment of food selectivity by texture.     

DEVELOPMENTAL ISSUES IN THE TREATMENT OF DIABETIC WOMEN

The physiological and psychological effects of diabetes on women show changes with age. Behavioral interventions on behalf of diabetic women must be based on an understanding of these life span changes. A review of selected articles from the medical and psychological literature that focus on special issues for a diabetic woman during preadolescence, adolescence, and adulthood is presented. Recommendations are made for behavioral interventions with diabetic women in regard to "sick" role adjustment, peer conformity pressures, eating disorders, sexuality, and pregnancy.
