Factors influencing therapist selection among gays,lesbians and bisexuals

For this study 609 gay, lesbian and bisexual individuals were surveyed with respect to openness about sexual orientation and preference for a therapist with a particular sexual orientation. Other factors considered important in selecting a therapist such as licensure, referral source, gender, cost and specialty were also examined. Data for this study was collected using two different methods. In the first method, data was collected from respondents subscribing to internet listervers serving gay, lesbian and bisexual subscribers. In the second, more traditional method, surveys were distributed by mail or hand delivered to various organizations serving gay, lesbian, and bisexual communities in two southwestern states. Findings suggest that significantly more lesbians than gay men and bisexuals in the e-mail sample prefer a therapist of the same sexual orientation. No significant relationships were found between degree of openness and importance of the therapist's sexual orientation. Other factors related to therapist preference were explored, and results are discussed.

A transformation of respondently conditioned stimulus function in accordance with arbitrarily applicable relations.

Adult male subjects saw a sexual film clip paired with a nonsense syllable (C1). Similarly, an emotionally neutral film clip was paired with a second nonsense syllable (C3). Responses to the nonsense syllables were recorded as skin resistance responses. Subjects were also trained in a series of related conditional discriminations, using the C1 and C3 stimuli, from which the following equivalence relations were predicted; A1-B1-C1, A2-B2-C2, and A3-B3-C3. Some subjects were given matching-to-sample (equivalence) tests after the conditional discrimination training (Experiment 1), whereas others were not (Experiment 2). Subjects were tested for a transformation of eliciting functions by presenting the A1 and A3 stimuli, which were related through equivalence to C1 and C3, respectively. Five of the 6 subjects who showed significantly greater conditioned responses to C1 than to C3, also showed significantly greater skin resistance responses to A1 than to A3. Two additional subjects demonstrated a transformation of an eliciting stimulus function in accordance with five-member equivalence relations (Experiment 3), and another 5 subjects demonstrated similar effects in accordance with the relations of sameness and opposition (Experiment 4).     

Effects of Age on the Generalization and Incubation of Memory in the F344 Rat

Freezing (immobility) in the presence of aversive stimuli is a species-specific behavior that is used as an operational measure of fear. Conditioning of this response to discrete sensory stimuli and environmental context cues has been used as a tool to study the neuropsychology of memory dynamics and their development over the lifespan. Three age groups of F344 rats (3, 9, and 27 month) received tone–foot shock pairing (or tone only) in a distinctive chamber on two consecutive days. Separate subgroups of rats from each age group were then tested, at retention intervals of 1, 20, 40, or 60 days, for context-mediated fear in the environment in which they were trained, for generalization of the fear response to a novel chamber, and for fear of the tone. Beginning at day 20, the 27-month-old rats exhibited less freezing behavior than did younger rats when tested in the conditioning context. This age difference was a result of freezing behavior becoming progressively stronger with time in the two younger age groups, a phenomenon that has been referred to as memory incubation. Incubation of the contextual fear response was not detected in the old rats. In a novel context, all age groups exhibited significantly more freezing than did control animals. There was also pronounced incubation of this generalized freezing response, and the extent of incubation declined significantly with age. In the novel context, the freezing response to the tone was robust in all age groups and increased over time, in constant proportion to the degree of freezing elicited by the novel context itself, prior to tone onset. The fact that old animals are known to be relatively selectively impaired in forms of memory that depend on a functional hippocampus suggests a possible explanation for the reduced incubation effects seen in old rats; however, whether the increased expression of fear over time is mediated by a hippocampal-dependent memory consolidation process or whether it reflects a generalized increase in the gain of the circuitry mediating the fear response itself, remains to be determined.     

In defense of the advance specification hypothesis for motor control

Summary Choice reaction times often depend on the relations between the responses that are possible. Rosenbaum, Inhoff, and Gordon (1984) accounted for these effects with an advance specification (AS) hypothesis, according to which subjects prepare for a choice by creating a single motor program with the features shared by the response alternatives; after the choice signal is presented, subjects are assumed to fill in the features that were missing. In a recent article, Heuer (1987) argued that the AS hypothesis cannot account for a number of results that he has obtained. He suggested hat a better hypothesis relies on the idea of programming interactions (PI), according to which programs for alternative responses have mutual facilitative or inhibitory influences, depending on their similarity. Heuer (1987) reported an experiment that was partly consistent with the PI hypothesis and, as implied by him, inconsistent with the AS hypothesis. We show that the results of this experiment, as well as the results of Heuer's earlier experiments, are in fact consistent with the AS hypothesis and inconsistent with the PI hypothesis. We show in addition that there are a number of logical problems with the PI hypothesis which make it a less attractive model of choice than the AS hypothesis.Supported in part by National Science Foundation grant BNS-8710933 and a Research Career Development Award from the National Institutes of Health to the first author.
