Caregiver preference for reinforcement‐based interventions for problem behavior maintained by positive reinforcement

Social validity of behavioral interventions typically is assessed with indirect methods or by determining preferences of the individuals who receive treatment, and direct observation of caregiver preference rarely is described. In this study, preferences of 5 caregivers were determined via a concurrent‐chains procedure. Caregivers were neurotypical, and children had been diagnosed with developmental disabilities and engaged in problem behavior maintained by positive reinforcement. Caregivers were taught to implement noncontingent reinforcement (NCR), differential reinforcement of alternative behavior (DRA), and differential reinforcement of other behavior (DRO), and the caregivers selected interventions to implement during sessions with the child after they had demonstrated proficiency in implementing the interventions. Three caregivers preferred DRA, 1 caregiver preferred differential reinforcement procedures, and 1 caregiver did not exhibit a preference. Direct observation of implementation in concurrent‐chains procedures may allow the identification of interventions that are implemented with sufficient integrity and preferred by caregivers.     

The Combined Effects of Measurement Error and Omitting Confounders in the Single-Mediator Model

Mediation analysis requires a number of strong assumptions be met in order to make valid causal inferences. Failing to account for violations of these assumptions, such as not modeling measurement error or omitting a common cause of the effects in the model, can bias the parameter estimates of the mediated effect. When the independent variable is perfectly reliable, for example when participants are randomly assigned to levels of treatment, measurement error in the mediator tends to underestimate the mediated effect, while the omission of a confounding variable of the mediator-to-outcome relation tends to overestimate the mediated effect. Violations of these two assumptions often co-occur, however, in which case the mediated effect could be overestimated, underestimated, or even, in very rare circumstances, unbiased. To explore the combined effect of measurement error and omitted confounders in the same model, the effect of each violation on the single-mediator model is first examined individually. Then the combined effect of having measurement error and omitted confounders in the same model is discussed. Throughout, an empirical example is provided to illustrate the effect of violating these assumptions on the mediated effect.     

Extended Schema Mode conceptualizations for specific personality disorders: an empirical study

The aim of this study was to investigate newly formulated schema mode models for cluster-C, paranoid, histrionic and narcissistic personality disorders. In order to assess 18 hypothesized modes, the Schema Mode Inventory (SMI) was modified into the SMI-2. The SMI-2 was administered to a sample of 323 patients (with a main diagnosis on one of the PDs mentioned) and 121 nonpatients. The SMI-2 was successful in distinguishing patients and controls. Newly formulated modes proved to be appropriate for histrionic, avoidant, and dependent PD. The modification of the Overcontroller mode into the Perfectionistic and Suspicious Overcontroller mode was valuable for characterizing paranoid and obsessive-compulsive PD. The results support recent theoretical developments in Schema Therapy, and are useful for application in clinical practice.     

Semantic Similarity of Alternatives Fostered by Conversational Negation

Conversational negation often behaves differently from negation as a logical operator: when rejecting a state of affairs, it does not present all members of the complement set as equally plausible alternatives, but it rather suggests some of them as more plausible than others (e.g., “This is not a dog, it is a wolf/*screwdriver”). Entities that are semantically similar to a negated entity tend to be judged as better alternatives (Kruszewski et al., 2016). In fact, Kruszewski et al. (2016) show that the cosine similarity scores between the distributional semantics representations of a negated noun and its potential alternatives are highly correlated with the negated noun-alternatives human plausibility ratings. In a series of cloze tasks, we show that negation likewise restricts the production of plausible alternatives to similar entities. Furthermore, completions to negative sentences appear to be even more restricted than completions to an affirmative conjunctive context, hinting at a peculiarity of negation.     

Relational Complexity and Ethical Responsibility

Richard Miller uses the concepts of alterity and intimacy as touchstones for analyzing neglected aspects of our interpersonal and social relationships. He argues that, as persons in relation, we oscillate between experiences of alterity and intimacy, and it is with a greater awareness of this oscillation that we do best to consider our ethical responsibilities. This paper affirms the value of thinking about—and potentially reimagining—how we conceive and relate to various others. It also makes explicit that, as persons, each of us is separate, not only from some, but from all other persons, even as we are also one with them. Moreover, each of us is different from all other persons, even as we are also like them. The aspects of persons and relationships on which we focus, in a given situation, matter because they partly determine the choices that we make in another’s regard.
