A titration procedure for generating escape behavior

In a grid-shock escape paradigm using time-out as reinforcement, both fixed-ratio and variable-interval performances were established directly from a continuous reinforcement schedule with rats and guinea pigs. A procedure was developed that employed a stepwise decrease in reinforcement time for all responses except the terminal response. Acquisition and long-term maintenance data were obtained from Ss trained on this titrated negative-reinforcement procedure.     

An indigenous community mental health service on the Tohono O'odham (Papago) Indian reservation: Seventeen years later

The status of a fully indigenous mental health program serviced and controlled by the Tohono O'odham (Papago) Indian tribe is reviewed from the perspective of its 17-year history. The program functions in large measure in a crisis intervention model, with suicidal or acutely disturbed cases being most frequent. However, a whole range of disorders and ages are seen. Traditional Medicine Men and Women are often used as consultants, as are some professionals. In recent years child sex abuse and abuse of drugs among youth are prominent problems. The program experienced problems of obtaining services off reservations for patients in need, and in establishing credibility of the Indian Mental Health workers with the outside service providers.     

Clinical Use of the Surgeon General’s “My Family Health Portrait” (MFHP) Tool: Opinions of Future Health Care Providers

This study examined medical students’ and house officers’ opinions about the Surgeon General’s “My Family Health Portrait” (MFHP) tool. Participants used the tool and were surveyed about tool mechanics, potential clinical uses, and barriers. None of the 97 participants had previously used this tool. The average time to enter a family history was 15 min (range 3 to 45 min). Participants agreed or strongly agreed that the MFHP tool is understandable (98%), easy to use (93%), and suitable for general public use (84%). Sixty-seven percent would encourage their patients to use the tool; 39% would ensure staff assistance. Participants would use the tool to identify patients at increased risk for disease (86%), record family history in the medical chart (84%), recommend preventive health behaviors (80%), and refer to genetics services (72%). Concerns about use of the tool included patient access, information accuracy, technical challenges, and the need for physician education on interpreting family history information.     

Religion,Poverty, and Development

This article serves two purposes. First, it introduces the forum that follows in this issue on religion and development. Second, it serves as a review of the small but quickly growing literature on how religion interacts with efforts by (often religious) people and organizations to ameliorate poverty worldwide. We address the need to define both “religion” and “development” with clarity and precision. We also call for further research in this area by sociologists, particularly at a time when the landscape of development practice is shifting, from changes in funding sources and priorities to competition between religious and secular organizations.     

The dynamics of multimodal integration: The averaging diffusion model

We combine extant theories of evidence accumulation and multi-modal integration to develop an integrated framework for modeling multimodal integration as a process that unfolds in real time. Many studies have formulated sensory processing as a dynamic process where noisy samples of evidence are accumulated until a decision is made. However, these studies are often limited to a single sensory modality. Studies of multimodal stimulus integration have focused on how best to combine different sources of information to elicit a judgment. These studies are often limited to a single time point, typically after the integration process has occurred. We address these limitations by combining the two approaches. Experimentally, we present data that allow us to study the time course of evidence accumulation within each of the visual and auditory domains as well as in a bimodal condition. Theoretically, we develop a new Averaging Diffusion Model in which the decision variable is the mean rather than the sum of evidence samples and use it as a base for comparing three alternative models of multimodal integration, allowing us to assess the optimality of this integration. The outcome reveals rich individual differences in multimodal integration: while some subjects’ data are consistent with adaptive optimal integration, reweighting sources of evidence as their relative reliability changes during evidence integration, others exhibit patterns inconsistent with optimality.     

The promotion of self-forgiveness,responsibility, and willingness to make reparations through a workbook intervention

This study evaluated the effectiveness of a workbook intervention designed to promote self-forgiveness, acceptance of responsibility, and willingness to make amends/reparations in a university student sample. The intervention manual consisted of three parts: (a) promoting prosocial and responsible attitudes, (b) reducing barriers to self-forgiveness, and (c) promoting healthy thinking and behaviors. Outcome measures included acceptance of responsibility, motivation to make reparations, and state and trait self-forgiveness. Measures were administered pre-intervention and immediately post-intervention. Participants were randomly assigned to an intervention group (N = 50) or a control group (N = 43). The control group studied materials for their university courses instead of completing the intervention. Following the intervention, the intervention group had significantly a higher state and dispositional self-forgiveness post-test compared to the control group. Changes in acceptance of responsibility and willingness to make reparations did not reach statistical significance as compared to the control group.     

The effect of the order in which episodic autobiographical memories versus autobiographical knowledge are shared on feelings of closeness

Autobiographical memories (AMs) can be used to create and maintain closeness with others [Alea, N., &; Bluck, S. (2003). Why are you telling me that? A conceptual model of the social function of autobiographical memory. Memory, 11(2), 165–178]. However, the differential effects of memory specificity are not well established. Two studies with 148 participants tested whether the order in which autobiographical knowledge (AK) and specific episodic AM (EAM) are shared affects feelings of closeness. Participants read two memories hypothetically shared by each of four strangers. The strangers first shared either AK or an EAM, and then shared either AK or an EAM. Participants were randomly assigned to read either positive or negative AMs from the strangers. Findings suggest that people feel closer to those who share positive AMs in the same way they construct memories: starting with general and moving to specific.     

Gender,Sacrifices, and Variability in Commitment: A Daily Diary Study of Pregnant Heterosexual Cohabitors and their Partners

We use interdependence theory and the inertia model to examine how gender and daily relational sacrifices predict daily variability in relationship commitment across a week in 43 U.S. couples who are unmarried cohabitors expecting their first child together (total of 455 days of data). We examined three variants of daily relational sacrifices: frequency, ease, and awareness for both individuals and partners, and we tested for gender differences. Using an Actor Partner Interdependence Model (APIM), we found that both women and men reported lower variability in commitment when men were perceived as highly aware of the sacrifices made for them. Additionally, women experienced lower variability in commitment when their male partners reported engaging in easier sacrifices. In contrast, women reported higher variability in commitment when they reported greater frequency of sacrifices for their partner. The results can be of practical use for practitioners working with expectant cohabitors and their partners given the unique role gender plays relative to how sacrifices shape variability in daily commitment.     

Parenting Stress and Sexual Satisfaction Among First-Time Parents: A Dyadic Approach

The present paper reports on longitudinal associations between parenting stress and sexual satisfaction among 169 heterosexual couples in the first year after the birth of a first child. Actor Partner Interdependence Modeling (APIM) was used to model the effects of the mother’s and father’s parenting stress at 6 months after birth on sexual satisfaction at 1 year after birth. Based on social constructivist theory and scarcity theory, two hypotheses were posed: (a) mothers’ parenting stress will predict their own later sexual satisfaction whereas fathers’ parenting stress will not predict their own later sexual satisfaction (actor effects) and (b) mothers’ parenting stress will predict fathers’ later sexual satisfaction but fathers’ parenting stress will not predict mothers’ later sexual satisfaction (partner effects). On average, parents were only somewhat satisfied with their sex life. The first hypothesis was supported as greater parenting stress significantly predicted lower sexual satisfaction for mothers but not for fathers. The second hypothesis was also supported as mothers’ greater parenting stress significantly predicted less sexual satisfaction in fathers, whereas fathers’ parenting stress did not significantly predict mothers’ sexual satisfaction. We discuss how our results may be interpreted considering the social construction of gendered family roles.
