Homophobia or sexism? A systematic review of prejudice against nonheterosexual orientation in Brazil

Since it was coined in the 1970s, in the United States, the term “homophobia” has been invoked to define the prejudice against nonheterosexual orientation. Besides the US, the phenomenon has been detected in many contemporary societies, including Brazil. Prejudice against nonheterosexual orientation is strongly associated with the historical and social contexts in which it is embedded, which means that the term should not be used without a clear definition of its local specificities. This applies to the recent debate around homophobia in the Brazilian context. In an attempt to identify existing studies of prejudice against nonheterosexual orientations in Brazil, a systematic review was conducted in SciELO indexes, PubMed, PsycINFO, SCOPUS, and Web of Science. The articles were collected using the keyword “homophobia” and related terms, and “Brazil”, in the languages ??of the databases. The search returned 355 articles. Of these, 247 were removed because they were duplicates. The abstracts of 109 studies published between 1973 and 2011were analyzed. Thirty‐one articles were identified as relevant. The reviewed studies indicate that prejudice against nonheterosexual orientations is an evident and widespread phenomenon that is prevalent in various populations and contexts. Nevertheless, prejudice in Brazil is not homogeneous, and particular attention is necessary to the inequality of gender relations (sexism) and prejudice against gender nonconformity, which seem to explain, if not cause, most of the prejudice against nonheterosexual orientations. Although theoretically there is a clear distinction between sexual orientation and gender expression, from the standpoint of manifestation of prejudice that distinction seems to be more tenuous.     

Generativity and Political Participation in Old Age: A Mixed Method Study of Spanish Elders Involved in Political Organisations

This study has dual aims. First, it aims to explore the relationship between generativity and political participation, a neglected aspect of civic participation. Second, using different dimensions of generativity in a mixed methods study, it also aims to contribute to the theoretical and methodological literature on generativity as a multidimensional concept relevant to later life. This Spanish study involved a large survey utilising three different measures of generativity—generative concern, generative goals, and perceived cultural demands—to look for differences between older people actively engaged in political organisations and a comparison group. Results showed that older people from the two groups differed on all dimensions of generativity. Participants in political organisations showed significantly higher scores on generative concern, reported more generative goals in the present and future, and noted more perceived generative demands than comparison individuals. Overall, our findings suggest that generativity plays a key role in political engagement in later life, and, further, that our understanding of generativity in later life gains from a multidimensional assessment of the concept.     

Functions of the pointing gesture in mothers and their 12 to 36-month-old children during everyday activities

This study longitudinally examined the production of pointing in four Spanish 1-year-old and four Spanish 2-year-old children in interactive situations with their mothers at home over the course of one year. Three aspects were analyzed: a) the functions of the pointing gesture, their accurate comprehension by the interlocutor (mother or child), and their order of emergence in the child; b) whether or not there were differences in the production of pointing according to who initiated the interaction; and c) whether maternal and child speech were related to maternal and child pointing production. The results showed that the pointing function of showing is the most frequent for both children and mothers from groups 1 and 2, and the first to emerge followed by the informing, requesting object, requesting action, and requesting cooperation functions. The accuracy with which these intentions were comprehended was found to be very high for both mother and child. Pointing production was greater when the speaker initiated the interaction than when the other person did, indicating that gestures follow the turn-taking system. Finally, the production of pointing to showing in children and mothers was found to be related to maternal and child speech, while pointing to request cooperation triggered the process of joint activity between mother and child.     

Quality of maternal thinking and mother-child interaction in at-risk contexts

This study investigates how the maternal level of perspectivistic reasoning and the level of socialization goals in the representation of their actions are related to the quality of mother-child behaviors as well as to the expert ratings on maternal practices in at-risk contexts. It also investigated whether there is any direct link between mother and child behaviors and expert ratings. A sample of 75 mothers of children between 8 and 12 years old reported on their level of perspectivistic reasoning and were characterized by the social workers of municipal services as being coercive, neglectful or meeting their child's needs. Interactions during a collaborative task were observed to obtain information on level of socialization goals and mother-child behaviors. Structural equation models showed that mothers' higher levels of perspectivism and higher levels of socialization goals positively predicted the mother's and child's sensitivity and active involvement in the task and negatively predicted avoidance and passivity. Higher levels of perspectivism consistently predicted experts' views on maternal practices. However, only mother's avoidance predicted negatively expert ratings on coercion practice, indicating that expert views were mostly derived from the mothers' perspective on their child. The implications of these results for parental assessment and intervention programs are discussed.     

Generalization gradients in a navigation task with rats

In two experiments in a Morris pool, rats were trained to find a hidden platform which was located in a specific position in relation to two objects, B and F, which were presented together, one in front of the other. One object, B, was just above the platform (a beacon for the platform, the critical object) while the second object, F, was above the edge of the pool (the frame of reference). Then the rats received test trials, without the platform, in which B was presented in different positions in relation to F (i.e., in relation to its original position). In the two experiments the test results showed a generalization gradient as a function of the relative distance of the two objects: more time searching in the B segment, where the platform should have been, when B was in the original position (i.e., in front of F), which decreased symmetrically with distance of B from F. The present experiments show for the first time generalization gradients with rats across spatial locations when working with a navigation task.

On the nature of the conjunction fallacy

In a seminal work, Tversky and Kahneman showed that in some contexts people tend to believe that a conjunction of events (e.g., Linda is a bank teller and is active in the feminist movement) is more likely to occur than one of the conjuncts (e.g., Linda is a bank teller). This belief violates the conjunction rule in probability theory. Tversky and Kahneman called this phenomenon the “conjunction fallacy”. Since the discovery of the phenomenon in 1983, researchers in psychology and philosophy have engaged in important controversies around the conjunction fallacy. The goal of this paper is to explore the most important of these controversies, namely, the controversy about the nature of the conjunction fallacy. Is the conjunction fallacy mainly due to a misunderstanding of the problem by participants (misunderstanding hypothesis) or is it mainly due to a genuine reasoning bias (reasoning bias hypothesis)? A substantial portion of research on the topic has been directed to test the misunderstanding hypothesis. I review this literature and argue that a stronger case can be made against the misunderstanding hypothesis. Thus, I indirectly provide support for the reasoning bias hypothesis.
