The aim was to determine the sexual and reproductive risk behaviour in Huancayo college students from a private institution. One is a research, cross-sectional, exploratory and descriptive, the sample nonprobabilistic was conform by 254 young students, the Self-efficacy test was used for AIDS (SEA27) that measures self-efficacy in risk behaviours for AIDS infect, thus also collected data on sexual attitude, knowledge and information acquisition in sexuality, data were digitates, stored and analyzed in SPSS statistical program. Results demonstrated about selfefficacy risk behaviours that masculine gender had one self-efficacy average under 43,6 %, whereas feminine gender showed to have one self-efficacy...

According to the concept of allostasis and its association with energy mobilization, glucocorticoids (GCs) should parallel cumulative energy expenditure for animal survival and reproduction. Therefore, it is expected that seasonal food shortages might lead to increased levels of GCs. We tested this hypothesis by analyzing the intra-annual variation of fecal glucocorticoid metabolites (GCM) in 14 wild black capuchin monkeys (Sapajus nigritus) living in a social group in the Brazilian Atlantic Forest. We analyzed the association between GCM and social and environmental variables for the three age/sex classes (adult males, adult females and immatures [juveniles and infants]). Decreased fruit intake during...

Successive Negative Contrast (SNC) is a phenomenon in which there is a sharp decrease in the rate of reinforced behavior immediately after a sudden reduction in quality or quantity of a habitual reinforcer. This phenomenon has become a solid experimental paradigm for the study of frustration in mammals but it has not been reported to date in the Mongolian gerbil (Meriones unguiculatus). This species is monogamous and biparental, and these differential characteristics make it interesting for comparative analysis. This work includes modifications to the SNC paradigm for this species, assessing its response to sudden changes in positive reinforcement and its...

In the last common ancestor of modern humans and the three living African ape species a genetic mutation occurred that increased the rate that alcohol was metabolized. This fact initially supports the "drunken monkey hypothesis" which states that natural selection should have favoured individuals that routinely incorporated alcohol- and thus energy-rich fruits into their diet. However, random observations from apes living in the wild do not provide evidence for such kind of choosey feeding behaviours. To investigate whether or not the living great apes have evolved a preference of alcohol-rich fruits over normal ripe fruits we performed a bioassay with...

The effect of the presence of a con-specific in the temporal organization of food hoarding was studied in two varieties of Syrian hamster (Mesocricetus auratus): golden and long-haired. Four male hamsters of each variety were used. Their foraging behavior was observed during four individual and four shared trials in which animals were not competing for the same food source or territory. During individual trials, long-haired hamsters consumed food items directly from the food source, transporting and hoarding only remaining pieces. During shared trials, the long-haired variety hoarded food items before consumption, and increased the duration of hoarding trips, food handling...

The present study presents a procedure to assess the property of symmetry by comparing the acquisition of conditional relations that are consistent and inconsistent with this property in a capuchin monkey (Sapajus spp.). One young male monkey underwent arbitrary matching-to-sample training. The experiment had four phases: Phase 1.1 (establishing A1B1 and A2B2 relations), Phase 1.2 (reinforcing B1A1 and B2A2 relations, consistent with the property of symmetry), Phase 2.1 (establishing A3B3 and A4B4 relations), and Phase 2.2 (reinforcing B3A4 and B4A3 relations, inconsistent with the property of symmetry). A comparison between Phase 1.2 (consistent) and Phase 2.2 (inconsistent) showed faster acquisition...

The current study of preschool children characterizes a semi-natural extension of experimental questions on how human ancestors evaded predation when encountering dangerous felids. In a pretend game on a playground, we presented full-size leopard and deer models to children (N = 39) in a repeated-measures experimental design. Prior to viewing the model presented 15-m away, each child was instructed by the experimenter to go where she or he would feel safe. The rationale for this study was based on the anthropological construct of “sexual dinichism,” positing that, during the Pliocene, smaller-bodied hominin females engaged in more arboreal behavior than larger-bodied...

When a prolonged observation of groups of rats in a seminatural environment is used as testing procedure, different behavioral patterns are shown compared with what observed in a pair housed in a small cage. Males and females copulate simultaneously, they show a promiscuously and random copulatory pattern. Females remain completely receptive from the first lordosis displayed in the period of behavioral estrus until the last. There is no reduction in paracopulatory behaviors and no increase in rejections towards the end of estrus. Female paracopulatory behavior and receptivity change in a most abrupt way at both initiation and termination of behavioral...

Human gambling generally involves taking a risk on a low probability high outcome alternative over the more economically optimal high probability low outcome alternative (not gambling). Surprisingly, although optimal foraging theory suggests that animals should be sensitive to the overall probability of reinforcement, the results of many experiments suggest otherwise. For example, they do not prefer an alternative that 100% of the time provides them with a stimulus that always predicts reinforcement over an alternative that provides them with a stimulus that predicts reinforcement 50% of the time. This line of research leads to the conclusion that preference depends on...

A new method was developed to concurrently investigate procedural memory and working memory in pigeons. Pigeons performed a sequence of keypecks across 3 response keys in a serial response task, with periodic choice probes for the location of a recently produced response. Procedural memory was operationally defined as decreasing response times to predictable cues in the sequence. Working memory was reflected by accurate responses to the choice probes. Changing the sequence of required keypecks to a random sequence interfered with procedural memory in the form of slowed response times, but did not prevent pigeons from effectively using working memory to...

Animal models have been broadly used in the study of pathophysiology and molecular and neurochemical pathways in neuropsychiatric diseases. Different approaches have used both consanguineous and non-consanguineous mice models to model behavioral patterns associated with the maniac spectrum. However, the disadvantages of validating clinical and experimental protocols have hindered the replication of these studies. In this article, the advantages and disadvantages of using consanguineous lines and non-consanguineous stocks in mice animal models for the study of mania and its subtypes are discussed. Additionally, new experimental alternatives to advance the pathogenesis and pharmacogenetics of mania using animal models are proposed and...

Numerosas veces la inadaptación social culmina en medidas punitivas y restrictivas A menudo,
estas no se centran en la posibilidad de escuchar a la expresión interna o en alternativa al desarrollo de estos individuos. A menudo, las estrechas puertas de las cárceles se convierten
también en una oscuridad sin puertas.
La experiencia de las artes (basado en los principios de la terapia de las artes expresivas) puede
funcionar en estas personas como guía que conduzca al descubrimiento de los orígenes de la ira, y
permitiéndoles ser activos y creativos en su propio proceso de recuperación.
En este texto los autores tienen la intención de reflexionar sobre...

The article pretends to reflect the socio-cultural panorama in terms of gender equality, presenting
an objective point of view and within a collaborative frame. This essay it is the outcome of
matching the gender issue and the cultural production, as a way of creating knowledge from an
alternative pedagogy. This pedagogy is concerned about the individual, as well as, the group by
itself. In this summary some artistic projects based on this method are included.

Attention to diversity is one of the basic principles of the Spanish education system. Diversity
should be addressed by effective measures and of different types, and inclusive physical education is one of the areas that effectively contribute to the integral development of the
person, maturation and inclusion in society.
Through this article we present a didactic intervention from the own professional experience to
work to promote awareness and attitudes of tolerance and respect for diversity in students of
Science Degree in Physical Activity and Sport. With the proposed activities we seek that students
have the opportunity to experience the limitations, body sensations and emotions that arise...
