Effects of neonatal treatment with cyproterone acetate on aggressive behavior induced by footshock in adult male rats

High levels of androgens are required to organize aggressive behavior in adult male rats. Footshock-induced aggression was tested in Wistar rats allocated to one of three experimental groups: control (oil-injected) males (M), males neonatally injected with the antiandrogen cyproterone acetate (CA), and males treated as in the CA group but gonadectomized just before puberty (CAG). An antiaggressive effect of CA in those adult male rats neonatally treated with this compound was found. Neonatal exposure to cyproterone acetate exerts an antiandrogenic effect over the expression of shock-induced aggressive behavior. The behavioral effects of CA were not countered by adult treatment with testosterone propionate.     

In Search of the Language Switch: An fMRI Study of Picture Naming in Spanish–English Bilinguals

For many years, researchers investigating the brain bases of bilingualism have concentrated on two basic questions. The first concerns the nature of language representation. That is, are a bilinguals' two languages represented in distinct or overlapping areas of the brain. The second basic question in the neuropsychology of bilingualism concerns the neural correlates of language switching, that is, the areas that are active when bilinguals switch from one language to the other. Performance between single-language and dual-language picture naming was compared in a group of six Spanish–English bilinguals using behavioral measures and functional magnetic resonance imaging. Participants showed slower reaction times and increased activation in the dorsolateral prefrontal cortex in the mixed language condition relative to single language condition. There was no evidence that each language was represented in different areas of the brain. Results are consistent with the view that language switching is a part of a general executive attentional system and that languages are represented in overlapping areas of the brain in early bilinguals.     

Hemispheric specialization for word classes with visual presentations and lexical decision task

In the present paper we study the possible RH capabilities for the processing of adjectives and verbs of high frequency and medium imagery using a lexical decision task and a horizontal display. In the analysis of both RTs and mean errors, a RVF advantage is obtained. The interaction VF x Word Class did not reach significance. Therefore, we did not find evidence of differences in the visual-field effect for any syntactic class. These results support a LH superiority for the processing of both adjectives and verbs. For the nonword conditions (pseudoverbs and pseudoadjectives), no visual field differences were observed in either group. Methodological aspects are also discussed.     

Phenylpropanolamine inhibits feeding, but not drinking, induced by hypothalamic stimulation.

In rats bearing lateral hypothalamic electrodes that elicited both feeding and drinking, intraperitoneal injection of the appetite suppressant drug phenylpropanolamine (Propadrine) inhibited only feeding. This occurred whether feeding and drinking were tested simultaneously or separately. Selective inhibition of lateral hypothalamic feeding also followed injection of this drug through lateral, but not medial, hypothalamic electrode cannulas. We conclude that hypothalamically induced feeding is under some of the same pharmacological controls as spontaneous feeding, that this control may be exerted, in part, in or near the lateral hypothalamus, and that the neural systems which induce feeding and drinking during hypothalamic stimulation can be pharmacologically separated.     

Recent reformulations of Freud's development and abandonment of his seduction theory: historical/scientific clarification or a continued assault on truth?

It is well known that, as part of Freud's early work with "hysteria," he reported making discoveries of sexual abuse that he interpreted first as genuine but subsequently as fantasy. Several writers now argue that Freud never made such discoveries; rather that he lied about them, only inferred abuse from his patients' symptoms, or suggested false memories to his clients. The present authors evaluate Freud's original work and these recent claims and conclude that (a) they are not new and are similar to the original reaction that Freud received; (b) the assertion that Freud did not make discoveries of abuse is unwarranted; and (c) these recent writers frequently have supported their positions by misrepresenting what Freud actually wrote, ignoring evidence that contradicted their position, failing to consider obvious and more plausible explanations for Freud's behavior, and going beyond the available data and stating with certainty what cannot be determined.     

Adolescent Males' Knowledge and Attitudes About AIDS in The Context of Their Social World1

This study sought to find out how much total knowledge adolescents had concerning AIDS, what particular areas of knowledge were deficient, and how those areas might be related to attitudes and experiences in their social world. Seventy-eight adolescent males from one suburban and three urban high schools were interviewed. A 101-item questionnaire was used to assess: a) overall knowledge about AIDS; b) attitudes about sexuality, drugs, death, and AIDS and; c) related aspects of their social world, i.e., number of IV drug users known, and sources of information about AIDS. Analyses of variance were performed on overall knowledge of AIDS and on five content areas of knowledge. Race was shown to relate to significant differences in the knowledge scores. The social world associated with the urban samples were discussed as risk factors for minority youth. Different attitudes related to strengths and weaknesses in different areas of knowledge. Attitudes associated with deficiencies in different subareas of knowledge were discussed as additional risk factors and as presenting target areas for AIDS education efforts.     

Psychological distress with relationship satisfaction is moderated by anticipatory relational savoring among non-deployed military partners

This study recruited participants whose partners were deployed for active-duty military service to examine whether anticipatory relational savoring moderated the association of psychological distress with relationship satisfaction. Two weeks prior to their partner's deployment (T1), participants (N = 73) completed a self-report measure of relationship satisfaction. Then, 2 weeks into their partner's deployment (T2), participants completed self-report measures of stress, loneliness, and depression (combined into a composite index of psychological distress), and relationship satisfaction. Participants also completed a stream-of-consciousness task at T2 in which they imagined and discussed their partner's return from deployment. We coded the stream-of-consciousness task for anticipatory relational savoring regarding their upcoming reunion with their deployed partner. We found that anticipatory relational savoring moderated the association of psychological distress with during-deployment relationship satisfaction after adjusting for demographics, interpersonal variables, and deployment-specific variables; the association did not hold after adjusting for pre-deployment relationship satisfaction, and thus was robust when considering the distress-satisfaction association during the deployment but was not when considering changes in relationship satisfaction from pre- to during-deployment. We discuss the potential importance of anticipatory relational savoring for this unique population.     

National Registry of Psychotherapies

In the United States, there is a National Registry of Evidence-Based Programs and Practices (NREPP), which is a listing of treatments and interventions in psychotherapy. In 2012, NREPP invited our research team to submit an application for registration of our short-term interpretive group therapy for patients experiencing complicated grief, which we had used since 1986. From the beginning, we experienced difficulties that seemed to be largely attributable to a lack of professional skills required of the director. The director and her team used the metaphor of American football to describe parts of application process. Despite continuing difficulties, we finally completed the application process on time. Eventually, the reviews of the application were completed and the application was approved. The information we provide in this article mainly concerns the trials and tribulations associated with the application process. Overall, the process was frustrating and time-consuming. Consideration of additional variables, such as patient personality characteristics, would likely have provided a more useful set of findings.     

Think manager—think male,think follower—think female: Gender bias in implicit followership theories

Because of the overlap between the social roles of women and followers, we predicted that people would show a bias, that is, favor female followers over male followers. To support this hypothesis, we conducted two studies: An explicit test of the bias using a scenario design and an implicit association test (IAT)‐based study. Both studies show that the role of an ideal follower is more strongly associated with the female gender role, which seems to be caused partly by a more communal connotation of the follower role. This effect might contribute to the underrepresentation of women in leadership positions as they are perceived to be an ideal fit for followership positions; but it may also push men away from being followers and into leadership positions.     

A preliminary evaluation of the emergence of novel mand forms

Strategies that produce generalized responding are valuable, especially with regard to language acquisition, because relatively little training may result in large behavior changes. Conditions that result in generalized manding were analyzed in the current study. We demonstrated in reversal designs that undesirable or single-word responses were the predominant mand forms of 3 preschool children. Multiple baseline designs with 2 participants and a reversal design with 1 participant were then used to demonstrate the extent to which differential reinforcement of single-word mands (e.g., "cars") or framed mands (e.g., "I want the cars, please") would result in the emergence of other single-word and framed mands for different items (e.g., mands for music, puppets, or puzzles). Results showed that prompting and differential reinforcement of one or two mand frames resulted in the emergence of other framed mands for all participants.
