Relationships among compulsive hoarding, trauma, and attention-deficit/hyperactivity disorder

The current study investigated aspects of post-traumatic stress disorder and attention deficit/ hyperactivity disorder (ADHD) among hoarders. Compared to a sample of 36 controls, hoarders (n=26) reported a significantly greater number of different types of trauma, more frequent traumatic experiences, more symptoms of inattention, hyperactivity, and greater comfort derived from possessions. These findings are consistent with previous reports of extensive comorbidity associated with hoarding behaviors, and may reflect the potential usefulness of assessing PTSD and ADHD symptoms at the outset of hoarding treatments, as well as considering alternative pharmacological interventions.     

The use of an escape contingency and a token economy to increase food acceptance

Escape (termination of a meal) and token-based differential reinforcement of alternative behavior were used as reinforcement to increase acceptance of food. Using a changing criterion design, the number of bites accepted and consumed was gradually increased to 15 bites per meal. These data suggest that, in some cases, escape may be a potent reinforcer for food acceptance.     

A multilevel analysis of the interpersonal behavior of socially anxious people

We investigate the interpersonal behavior of socially anxious (SA) and non-socially anxious (NSA) individuals at three different levels of analysis, focusing on the dimensions of warmth and dominance. Study 1 examines self-reported general interaction styles, Study 2 explores behavior occurring within the context of a single interaction, and in Study 3 we focus on the performance of a single conversational act (a disagreement). Studies 1 and 2 adopt the framework of Interpersonal Circumplex Theory (IPC; Kiesler, 1983), which is well suited for studying trait-level and interaction-level social behaviors, while Study 3 is grounded in Politeness Theory (PT; Brown & Levinson, 1987), which can be used to analyze individual acts at the microstructural level. The potential mutual relevance of PT and IPC is also discussed.     

Gait transitions are not dependent on changes in intralimb coordination variability

The HKB model (H. Haken, J. A. S. Kelso, & H. Bunz, 1985) of coordination has been predominantly applied to upper extremity stationary movements. It predicts increased variability of relative phase before a transition and a decrease after a transition. The authors of the present study extended the intralimb lower extremity locomotive research of F. J. Diedrich and W. H. Warren (1995) by conducting continuous treadmill walk-to-run and run-to-walk trials with 10 participants. Standard deviation of knee-ankle and hip-ankle relative phase did not increase before walk-to-run and run-to-walk transitions, and there was no decrease in knee-ankle relative phase variability after either transition. The results of this study did not provide strong support for application of the variability predictions of the HKB model of coordination to lower extremity intralimb coordination during gait transitions.     

CHALLENGES FACING FEMALE DOCTORAL STUDENTS AND RECENT GRADUATES

Although increasing the numbers of women and minority faculty in academia is a widely held goal, their numbers remain small. The presence of women and minorities decreases disproportionately at each ascending rung of the academic ladder. This investigation identified factors potentially contributing to attrition in White and non-White women at a critical stage in their careers: as doctoral candidates and recent graduates. Two-hundred and twenty-four women in the life sciences, social sciences, and the humanities described their most pressing professional and personal concerns and offered suggestions for changes in their fields and in academia more generally. Independent raters coded responses by thematic content. Differences in responses by field, educational status, and minority status were examined. The most frequently cited concerns involved practical issues such as finding employment, financial stability, and developing professional expertise, revealing wide-spread concerns about a competitive academic climate. Suggestions included modifications in professional conduct, the employment and pay structure, and training.     

Establishing and maintaining a low-cost zebrafish breeding and behavioral research facility

The purpose of this paper is to describe how to establish and maintain a low-cost zebrafish facility that can be used for both teaching and research purposes. The cost of the facility ranges from about 250 to250 to 1,000, depending on the size of the facility and the experiments that will be conducted. The facility plan presented here also has the advantage that it can be disassembled so that it need not function year-round. A detailed list of supplies and materials is provided, along with detailed instructions on how to set up and maintain the adult and breeding portions of the facility. Finally, there is discussion of some of the general uses of a zebrafish facility, including a variety of procedures that are currently being used in behavioral research with this species.     

A behavioral technique for recovery from the psychological trauma of hysterectomy

Three groups of women (ns = 10) undergoing hysterectomy were subjects in an evaluation of biofeedback and relaxation techniques applied to recovery from psychological trauma of hysterectomy. Dependent measures included requests of pain medications, anxiety levels, finger-tip temperature, subjective units of discomfort, and number of days post-operative care. Although the results were mixed on most variables, the number of days post-operative care was significantly less in the relaxation/biofeedback group.     

Acquiring complex partial orderings in comparison with acquiring similar-sized linear orderings

The acquisition of a 14-term partial ordering was compared with the acquisition of a 14-term linear ordering. Learning the partial ordering was found to be more difficult because of two factors: (1) Subjects do not appear to have in their knowledge systems a prototype or rule for representing a long list of comparative relations as a partial ordering structure, and (2) the partial ordering must be presented so that some of the adjacently presented premises do not contain a common element. When these two factors were controlled, the partial ordering was as easy to learn as the linear ordering. It was also found that subjects learning the partial ordering showed no evidence of a serial position learning curve, whereas subjects learning the linear ordering showed some tendency to produce a serial position learning curve.     

Taking Access to the Community: An Ecological Systems Framework for In‐Home Counseling With Older Adults

Bronfenbrenner's (1977) ecological systems theory is a holistic framework placing an individual in a system's context to address their concerns. This article offers a case study demonstrating use of the theory with older adults and the in‐home setting. Implications for the counseling field and future research needs are discussed.
