Effects of decreasing intersession interval duration on graduated exposure treatment during simulated routine dental care

Reports suggest that individuals with developmental disabilities often engage in behavior during dental visits that precludes regular dental care. Graduated exposure therapies are an effective treatment for avoidant behavior in people with developmental delays, and some studies show that the duration of the intersession interval (ISI) can impact the effectiveness of graduated exposure treatments for typically developing individuals. The current study examined the effects of decreasing ISI on outcomes of a graduated exposure treatment during simulated routine dental care for 3 individuals diagnosed with autism. Treatment consisted of graduated exposure and extinction for disruptive behavior. Initially, sessions were conducted once per week. In subsequent conditions, treatment sessions were conducted 3‐5 times per week. A nonconcurrent multiple baseline across subjects design was used to demonstrate experimental control. Results suggest that decreasing ISI durations can produce improved treatment outcomes.     

Simple discrimination training with differential responses to establish functional and equivalence classes with preschool children

The present study assessed whether simple discrimination training with differential responses would produce functional and equivalence classes with preschool children. In Experiment 1, we exposed 10 children to simple successive discrimination training in which they had to press different buttons (selection‐based responses). Response 1 (R1) was reinforced only in the presence of A1, B1, or C1, and Response 2 (R2) was reinforced only in the presence of A2, B2, or C2. We assessed the formation of functional classes by training new selection responses in the presence of one member of each class (A1‐R3, A2‐R4) and testing to see if these responses would occur in the presence of other members. Eight children responded consistently with functional class formation. Four of these eight children also responded consistently with the formation of equivalence classes. Experiment 2 investigated whether differential motor responses (i.e., gestures) would improve equivalence class yields. Three of six children showed both functional and equivalence class formation. In general, the results indicate that the simple discrimination procedure with differential responses yielded functional and equivalence class formation.     

Considering the role of early discrimination experiences and the parent–child relationship in the development of disruptive behaviors in adolescence

Discrimination has been shown to be related to diminished psychological adjustment and greater risk for substance use when personally experienced by adolescents and when their caregivers experience discrimination. Our research considers the impact of primary caregiver experiences of racial- and socioeconomic-based discrimination in early (age 3–5 years) and late childhood (age 9½) on adolescent disruptive behaviors (age 14) with a large sample of diverse caregiver–child dyads (N = 634). In addition, we examine the potential protective effects of parent–child relationship quality in early and late childhood in buffering the effects of caregiver discrimination on adolescent disruptive behaviors. We also explore possible gender differences in children's vulnerability to engage in disruptive behaviors in the context of caregiver experiences of discrimination. The findings from this study indicate that at trend level, early childhood experiences of primary caregiver discrimination (ages 3–5) predicted adolescent disruptive behaviors, accounting for the effects of more recent (age 9½) caregiver discrimination. In addition, parent–child relationship quality at age 9½ years was found to buffer the effects of late childhood (age 9½) primary caregiver discrimination on adolescent disruptive behaviors for both male and female youth. The findings highlight the need for prevention and intervention techniques that foster healthy and positive primary caregiver–child relationships.     

Idealizations and Concretizations in Laws and Explanations in Physics

The paper tries to provide an alternative to Hempel’s approach to scientific laws and scientific explanation as given in his D-N model. It starts with a brief exposition of the main characteristics of Hempel’s approach to deductive explanations based on universal scientific laws and analyzes the problems and paradoxes inherent in this approach. By way of solution, it analyzes the scientific laws and explanations in classical mechanics and then reconstructs the corresponding models of explanation, as well as the types of scientific laws appearing in it. Finally, it compares this reconstruction with the approaches of J. Woodward and C. Hitchcock, C. Liu and with the views of M. Thalos on analytic mechanics.

Cerebellar patients demonstrate preserved implicit knowledge of association strengths in musical sequences

Recent findings suggest the involvement of the cerebellum in perceptual and cognitive tasks. Our study investigated whether cerebellar patients show musical priming based on implicit knowledge of tonal-harmonic music. Participants performed speeded phoneme identification on sung target chords, which were either related or less-related to prime contexts in terms of the tonal-harmonic system. As groups, both cerebellar patients and age-matched controls showed facilitated processing for related targets, as previously observed for healthy young adults. The outcome suggests that an intact cerebellum is not mandatory for accessing implicit knowledge stored in long-term memory and for its influence on perception. One patient showed facilitated processing for less-related targets (suggesting sensory priming). The findings suggest directions for future research on auditory perception in cerebellar patients to further our understanding of cerebellar functions.     

Is Structure Dependence an Innate Constraint? New Experimental Evidence From Children's Complex‐Question Production

According to Crain and Nakayama (1987) , when forming complex yes/no questions, children do not make errors such as Is the boy who smoking is crazy? because they have innate knowledge of structure dependence and so will not move the auxiliary from the relative clause. However, simple recurrent networks are also able to avoid such errors, on the basis of surface distributional properties of the input ( Lewis & Elman, 2001 ; Reali & Christiansen, 2005 ). Two new elicited production studies revealed that (a) children occasionally produce structure‐dependence errors and (b) the pattern of children's auxiliary‐doubling errors (Is the boy who is smoking is crazy?) suggests a sensitivity to surface co‐occurrence patterns in the input. This article concludes that current data do not provide any support for the claim that structure dependence is an innate constraint, and that it is possible that children form a structure‐dependent grammar on the basis of exposure to input that exhibits this property.     

Bigrams and the richness of the stimulus

Recent challenges to Chomsky's poverty of the stimulus thesis for language acquisition suggest that children's primary data may carry "indirect evidence" about linguistic constructions despite containing no instances of them. Indirect evidence is claimed to suffice for grammar acquisition, without need for innate knowledge. This article reports experiments based on those of Reali and Christiansen (2005) , who demonstrated that a simple bigram language model can induce the correct form of auxiliary inversion in certain complex questions. This article investigates the nature of the indirect evidence that supports this learning, and assesses how reliably it is available. Results confirm the original finding for one specific sentence type but show that the model's success is highly circumscribed. It performs poorly on inversion in related constructions in English and Dutch. Because other, more powerful statistical models have so far been shown to succeed only on the same limited subset of cases as the bigram model, it remains to be seen whether stimulus richness can be substantiated more generally.     

SCIENCE‐AND‐RELIGION/SPIRITUALITY/THEOLOGY DIALOGUE: WHAT FOR AND BY WHOM?

In recent years the science‐and‐religion/spirituality/theology dialogue has flourished, but the impact on the minds of the general public, on society as a whole, has been less impressive. Also, religious believers and outspoken atheists face each other without progressing toward a common understanding. The view taken here is that achieving a more marked impact of the dialogue would be beneficial for a peaceful survival of humanity. I aim to argue the why and how of that task by analyzing three possible purposes of the dialogue and their logical interdependence, suggest conceivable improvements of the quality and extent of the current efforts toward a negotiated action plan, and consider an enlargement of the circle of the actors involved. The dialogue that has been carried on between science and religion/spirituality/theology could be expanded and usefully applied to some major problems in the present world.     

The Presuppositions of Religious Pluralism and the Need for Natural Theology

In ‘The Presuppositions of Religious Pluralism and the Need for Natural Theology’ I argue that there are four important presuppositions behind John Hick’s form of religious pluralism that successfully support it against what I call fideistic exclusivism. These are i) the ought/can principle, ii) the universality of religious experience, iii) the universality of redemptive change, and iv) a view of how God (the Eternal) would do things. I then argue that if these are more fully developed they support a different kind of exclusivism, what I call rational exclusivism, and become defeaters for pluralism. In order to explain rational exclusivism and its dependence on these presuppositions I consider philosophers J.P. Moreland, William Lane Craig, and Alvin Plantinga, who offer arguments for their forms of exclusivism but I maintain that they continue to rely on fideism at important points. I then give an example of how knowledge of the Eternal can be achieved.

Constructive Logic with Strong Negation is a Substructural Logic. II

The goal of this two-part series of papers is to show that constructive logic with strong negation N is definitionally equivalent to a certain axiomatic extension NFL _ew of the substructural logic FL _ew . The main result of Part I of this series [41] shows that the equivalent variety semantics of N (namely, the variety of Nelson algebras) and the equivalent variety semantics of NFL _ew (namely, a certain variety of FL _ew -algebras) are term equivalent. In this paper, the term equivalence result of Part I [41] is lifted to the setting of deductive systems to establish the definitional equivalence of the logics N and NFL _ew . It follows from the definitional equivalence of these systems that constructive logic with strong negation is a substructural logic. Presented by Heinrich Wansing
