Histamine enhances inhibitory avoidance memory consolidation through a H2 receptor-dependent mechanism

Several evidences suggest that brain histamine is involved in memory consolidation but the actual contribution of the hippocampal histaminergic system to this process remains controversial. Here, we show that when infused into the CA1 region of the dorsal hippocampus immediately after training in an inhibitory avoidance task, but not later, histamine induced a dose-dependent promnesic effect without altering locomotor activity, exploratory behavior, anxiety state or retrieval of the avoidance response. The facilitatory effect of intra-CA1 histamine was mimicked by the histamine N-methyltransferase inhibitor SKF-91844 as well as by the H2 receptor agonist dimaprit and it was blocked completely by the H2 receptor antagonist ranitidine. Conversely, the promnesic action of histamine was unaffected by the H1 receptor antagonist pyrilamine, the H3 receptor antagonist, thioperamide, and the NMDAr polyamine-binding site antagonist ifenprodil. By themselves, ranitidine, pyrilamine, thioperamide, and ifenprodil did not affect IA memory consolidation. Our data indicate that, when given into CA1, histamine enhances memory consolidation through a mechanism that involves activation of H2 receptors; however, endogenous CA1 histamine does not seem to participate in the consolidation of IA memory at least at the post-training times analyzed.     

Genetic Counseling Services and Development of Training Programs in Malaysia

Genetic counseling service is urgently required in developing countries. In Malaysia, the first medical genetic service was introduced in 1994 at one of the main teaching hospitals in Kuala Lumpur. Two decades later, the medical genetic services have improved with the availability of genetic counseling, genetic testing and diagnosis, for both paediatric conditions and adult-onset inherited conditions, at four main centers of medical genetic services in Malaysia. Prenatal diagnosis services and assisted reproductive technologies are available at tertiary centres and private medical facilities. Positive developments include governmental recognition of Clinical Genetics as a subspecialty, increased funding for genetics services, development of medical ethics guidelines, and establishment of support groups. However, the country lacked qualified genetic counselors. Proposals were presented to policy-makers to develop genetic counseling courses. Challenges encountered included limited resources and public awareness, ethical dilemmas such as religious and social issues and inadequate genetic health professionals especially genetic counselors.

Self-reported expression and experience of triumph across four countries

Recent studies have suggested the existence of the emotion of triumph by documenting how its nonverbal signals are displayed and identified across cultures. The current study contributes to this literature by providing additional convergent evidence about the expression of triumph by examining self-reported expressions of triumph from participants from Japan, Russia, Serbia, and the U.S. Self-reported behavioral expressions of triumph were consistent with three factors previously found to be associated with the triumph expression (Expansion, Aggression, Attention), with the exception of a finding on one scale in one country. The Japanese were prone to report greater regulation compared to the experience of triumph, whereas Americans and Serbians reported relatively greater experience compared to regulation. Across countries, Aggression was positively correlated with self-reported experience. The self-reported expressions of triumph partially corresponded with nonverbal reactions that had been identified as triumph in previous research.     

Memory conjunction clusters: Influence of familiarity and recollection

In the memory conjunction paradigm, the number of times that constituents of conjunction lures were studied and the method of presentation were varied. In two experiments, participants were presented with eight parent items that could be recombined at test to form a conjunction lure. The constituents that were shared between the parent items and the conjunction lures were either presented in the same words (e.g., blackmail and jailbird presented four times each for the conjunction lure blackbird) or in different words (e.g., the targets footstool, footlocker, foothill, footbridge, baseball, softball, basketball, and golfball for the conjunction lure football). In both experiments, rates of false recognition were higher in the Different condition as opposed to the Same condition. These results provide evidence that participants in the Same condition were able to utilise a recall-to-reject strategy by remembering the repeatedly presented parent word. In the Different condition, participants were not able to utilise that strategy and instead relied on the familiarity of the repeatedly presented constituents which led to higher rates of false recognition.     

Eliciting information and cues to deceit through sketching in interpreter‐based interviews

As interviewees typically say less when an interpreter is present, we examined whether this was caused by interpreters not interpreting everything interviewees says or by interviewees providing less information. We further examined (a) the effect of a model drawing on providing information and (b) the diagnostic value of total details and the proportion of complications as cues to deceit. Hispanic, Russian, and South Korean participants were interviewed by native interviewers or by a British interviewer through an interpreter. Truth tellers discussed a trip they had made; liars fabricated a story. Participants received no instruction (condition 1) or were instructed to sketch while narrating without (condition 2) or with (condition 3) being given examples of detailed sketches. Interviewees said less when an interpreter was present because they provided less information. Truth tellers gave more details and, particularly, obtained a higher proportion of complications than liars. The sketching manipulation had no effect.     

Princesses,Princes, and Superheroes: Children's Gender Cognitions and Fictional Characters

The goal of the present study was to identify whether children recognize the gender stereotypes prevalent within the increasingly popular princess, prince, and superhero characters. Interviews with 126 children from the northeast region of the Unites States (3–11 years old) indicated that children recognized the gender-typed personality traits of princesses, princes, and superheroes, with older children holding more gender-typed cognitions about the characters. Children's own-schemas (i.e., beliefs that apply to themselves) and superordinate schemas (i.e., include beliefs about others' preferences and behaviors) for the characters were mostly gender typed and congruent. Older children gender-typed princesses as for girls more than younger children, whereas older children considered superheroes to be for boys and girls more than younger children did. Older children also considered the characters to be for them less, potentially reducing the negative implications of exposure to gender-typed messages associated with the characters. Individual differences exist in children's perceptions of these fictional characters, with children's own androgyny being positively correlated with their perceptions of princesses' androgyny levels. Further, girls were more flexible in their stereotyping of princesses, noting they were “for girls and boys” more. The authors discuss the results' practical and theoretical implications.     

Self-objectification and well-being in women's daily lives

Laboratory experiments and surveys show that self-objectification increases body shame, disrupts attention, and negatively predicts well-being. Using experience sampling methodology, the authors investigated self-objectification in the daily lives of 49 female college students. Building on the predictions of objectification theory, they examined associations between internalizing an observer's perspective on the self and psychological well-being, and examined the moderating roles of trait self-esteem and appearance-contingent self-worth. Within-person increases in self-objectification predicted decreased well-being, but this association was moderated by trait self-esteem and trait appearance-contingent self-worth; high self-esteem, highly appearance-contingent participants reported increased well-being when they self-objectified. Furthermore, perceived unattractiveness partially mediated the main effect and the three-way interaction: high self-esteem, highly contingent participants experienced smaller drops in well-being when they self-objectified, in part because they felt less unattractive. These results suggest that in daily life, some women receive a boost from self-objectification, although most women experience decreases in well-being when self-objectifying.
