Preference for human body odors is influenced by gender and sexual orientation

Human body odor may contribute to selection of partners. If so, sexual orientation may influence preference for and perhaps production of human body odors. In a test of these hypotheses, heterosexual and homosexual males and females made two-alternative forced-choice preference judgments for body odors obtained from other heterosexual and homosexual males and females. Subjects chose between odors from (a) heterosexual males and gay males, (b) heterosexual males and heterosexual females, (c) heterosexual females and lesbians, and (d) gay males and lesbians. Results indicate that differences in body odor are detected and responded to on the basis of, in part, an individual's gender and sexual orientation. Possible mechanisms underlying these findings are discussed.     

Making Sense in and of the Asexual Community: Navigating Relationships and Identities in a Context of Resistance

Despite some increased visibility in recent years, the asexual community and asexuality generally remain largely unknown. Aiming to demystify asexuality, this paper discusses the context of anti‐asexual animosity in which the (largely American) asexual community is situated. Specifically, the asexual community constructed itself in response to hostility, including explicit anti‐asexual discrimination, homophobia against asexual people perceived to be lesbian or gay, and the negative impact of (implicit) pathologising low sexual desire. This theoretical paper outlines some of the unique challenges asexual people face negotiating identities and relationships; the collective sense‐making strategies they use (generating language and discourse) to do so; and why these things are central to understanding asexual people's experiences. This is accomplished through a purposeful review of literature and a case study of the Asexual Visibility and Education Network as an asexual community space. Understanding the challenges asexual people face and the resources they invoke to overcome them helps applied psychologists develop the cultural competence they need to work effectively with the asexual people they will encounter.

Randomized, controlled trial of Behavioral Family Systems Therapy for Diabetes: maintenance and generalization of effects on parent-adolescent communication

We report a randomized trial of a revised Behavioral Family Systems Therapy for Diabetes (BFST-D) intervention. Families of 104 adolescents with diabetes were randomized to standard care (SC) or to 6 months of an educational support group (ES) or BFST-D. Family communication and problem-solving skills were assessed at 0, 6, 12, and 18 months by independent rating of videotaped family problem-solving discussions. BFST-D improved individual communication of adolescents and mothers, but not fathers. BFST-D significantly improved quality of family interaction compared to SC (10 of 12 comparisons) and ES (6 of 12 comparisons). Changes in family communication were differentially associated with changes in glycemic control, adherence, and family conflict. BFST-D improved family communication and problem solving relative to SC and modestly relative to ES.     

Clamped Corticosterone (B) Reveals the Effect of Endogenous B on Both Facilitated Responsivity to Acute Restraint and Metabolic Responses to Chronic Stress

To determine the effects of both corticosterone (B) and chronic stressors on acute ACTH responses to restraint, young male rats were exposed to streptozotocin-induced diabetes, cold (5-7 degreesC) or intracerebroventricular (icv) neuropeptide Y (NPY) for 5 d and then exposed to restraint within 2 h after lights on. Two groups of rats were studied: intact and adrenalectomized replaced with B pellets that maintained plasma B in the normal mean 24-h range of intact rats. In addition to ACTH and B responses to restraint on d 5, body weight, food intake, fat depots, glucose and other hormones were measured to determine the role of stress-induced elevations in B on energy balance. ACTH responses to restraint were normal in intact rats subjected to diabetes or cold. By contrast, there was no ACTH or B response to restraint in NPY-infused intact rats. All 3 groups of chronically stimulated adrenalectomized rats with clamped B had facilitated ACTH responses to restraint compared to their treatment controls. Overall food intake increased in all groups of stressed rats; however, augmented intake occurred only during the light in intact rats and equally in the light and dark in B-clamped rats. White adipose depot weights were decreased by both diabetes and cold and increased by NPY in intact rats; the decreases with cold and increases with NPY were both blunted and changes in fat stores were not significant in adrenalectomized, B-clamped rats. We conclude that: 1. diabetes- and cold-induced facilitation of restraint-induced afferent input to hypothalamic control of the hypothalamo-pituitary-adrenal (HPA) axis is opposed in intact rats by the elevated feedback signal of B secretion; 2. NPY does not induce facilitation of afferent stress pathways; 3. chronic stimulation of the HPA axis induces acute hyperresponsiveness of hypothalamic neurons to restraint provided that the afferent input of this acute stimulus is not prevented by B feedback; 4. stimulus-induced elevations in B secretion result in day-time feeding; 5. insensitivity of both caloric efficiency and white fat stores to chronic stress in adrenalectomized, B-clamped rats results from loss of normally variable B levels.     

Wittgenstein's New Way of Talking to Himself

A lack of consensus persists as to whom exactly the dialogues of Wittgenstein's Philosophical Investigations are between: Wittgenstein and an interlocutor? Or perhaps a variety of interlocutors, none of whom can be identified with Wittgenstein himself? I argue here that this lack of consensus is possibly due to an ambiguity in the ordinary concept of “talking to oneself,” and that a new concept of “talking to oneself” appropriate to Wittgenstein's dialogues is needed to properly understand them. Wittgenstein is talking to himself—but he is doing so in the way we talk to other people.     

The Type A behaviour pattern,induced mood,and the illusion of control

This study investigated the hypothesis that mood moderates the illusion of control among Type As and Bs. A facial positioning procedure was used to induce either positive, negative, or neutral moods in Type As and Bs during a control judgment task where no objective control was possible. Type Bs induced to experience a positive mood perceived greater control than did Type Bs experiencing a negative mood. There was no effect of induced mood on judged control for Type As.     

BEHAVIORAL MANAGEMENT OF EXERCISE: CONTRACTING FOR AEROBIC POINTS

Behavioral contracting was used to encourage physical exercise among college students in a multiple-baseline design. Subjects deposited items of personal value with the experimenters, which they could earn back on fulfillment of two types of contract contingencies. Subjects selected weekly aerobic point criteria, which they could fulfill by exercising in the presence of other subjects. In addition, subjects contracted to observe and record the exercise of other subjects and to perform an independent reliability observation once each week, with both of these activities monitored by the experimenters. Results indicated that the contract contingencies produced increases in the number of aerobic points earned per week for seven of eight subjects, that the aerobic point system possesses several advantages as a dependent variable for behavioral research on exercise, and that inexperienced observers could be quickly trained to observe exercise behavior and to translate those observations into their aerobic point equivalents. Finally, in a followup questionnaire completed 12 months after the end of the study, seven of the eight subjects reported that they were earning more aerobic points per week than had been the case during the baseline condition of this experiment.
