Self‐regulation predicts risk‐taking through people's time horizon

In the context of decision‐making research, people's regulatory orientation mode (i.e., assessment and locomotion modes) has been included among the most prominent individual difference variables, which may potentially account for choice behaviour. Thus, the main objective of our experiment was to investigate the relations between habitual use of regulatory mode and risk‐taking through people's time horizon. Risk‐taking was appraised using a behavioural measure (i.e., BART) 1 month following evaluation of habitual use of regulatory mode. The findings revealed a significant negative association between the assessment mode and risk‐taking through individual differences in time horizon.     

Conditional Random Quantities and Compounds of Conditionals

In this paper we consider conditional random quantities (c.r.q.’s) in the setting of coherence. Based on betting scheme, a c.r.q. X|H is not looked at as a restriction but, in a more extended way, as \({XH + \mathbb{P}(X|H)H^c}\) ; in particular (the indicator of) a conditional event E|H is looked at as EH +  P(E|H)H ^c . This extended notion of c.r.q. allows algebraic developments among c.r.q.’s even if the conditioning events are different; then, for instance, we can give a meaning to the sum X|H + Y|K and we can define the iterated c.r.q. (X|H)|K. We analyze the conjunction of two conditional events, introduced by the authors in a recent work, in the setting of coherence. We show that the conjoined conditional is a conditional random quantity, which may be a conditional event when there are logical dependencies. Moreover, we introduce the negation of the conjunction and by applying De Morgan’s Law we obtain the disjoined conditional. Finally, we give the lower and upper bounds for the conjunction and disjunction of two conditional events, by showing that the usual probabilistic properties continue to hold.     

Numerical acuity of fish is improved in the presence of moving targets,but only in the subitizing range

There is controversy in comparative psychology about whether on the one hand non-symbolic number estimation of small (≤4) and large numbers involves a single mechanism (an approximate number system), or whether on the other hand enumeration of the numbers 1–4 is accomplished by a separate mechanism, an object tracking system. To date, support for the latter hypothesis has come only from the different ratio-dependency of performance seen in the two numerical ranges, a reading that has been criticized on several grounds. In humans, the two-system hypothesis is supported by evidence showing that manipulation of the physical properties of the stimuli (e.g., the motion of the items) has dissimilar effects on small- and large-number discrimination. In this research, we studied this effect on guppies. Initially, fish were trained to simultaneously discriminate two numerical contrasts having the same easy ratio (0.50): one in the small-number (2 vs. 4) range and one in the large-number (6 vs. 12) range. Half of the fish were presented with moving items; the other half were shown the same stimuli without motion. Fish were then subjected to non-reinforced probe trials in the presence of a more difficult ratio (0.75: 3 vs. 4 and 9 vs. 12). Under both static and moving conditions, the fish significantly discriminated 6 versus 12, but not 9 versus 12 items. As regards small numbers, both groups learned to discriminate a 0.50 ratio, but only fish tested with moving stimuli also discriminated 3 and 4 items. This differential effect suggests that fish may possess two separate systems for small- and large-number discrimination.     

Extensive training extends numerical abilities of guppies

Recent studies on animal mathematical abilities suggest that all vertebrates show comparable abilities when they are given spontaneous preference tests, such as selecting the larger number of food items, but that mammals and birds generally achieve much better performance than fish when tested with training procedures. At least part of these differences might be due to the fact that fish are usually trained with only one or two dozen trials while extensive training, sometimes with thousands of trials, is normally performed in studies of mammals and birds. To test this hypothesis, female guppies were trained on four consecutive numerical discriminations of increasing difficulty (from 2 vs. 3 to 5 vs. 6 items), with up to 120 trials with each discrimination. Five out of eight subjects discriminated all contrasts up to 4 versus 5 objects at levels significantly better than chance, a much higher limit than the 2 versus 3 limit previously reported in studies that provided fish with only short training sequences. Our findings indicate that the difference in numerical cognition between teleosts and warm-blooded vertebrates might be smaller than previously supposed.     

Systematic review of instruments measuring homophobia and related constructs

Since its conceptualization, the construct of homophobia has been the subject of many speculations about its specificity, reach, and possibility of empirical assessment. Several instruments have been created aiming to measure the prejudice against homosexuals. Peer‐reviewed articles of studies using measures to assess homophobia and related constructs were systematically reviewed in 4 databases (Medline, PsycINFO, ERIC, JSTOR). The articles were classified as they displayed evidence of the instrument's validity, reliability, or both. Finally, the instruments were rated according to that evidence. Out of 1076 results, 115 studies between 1993 and 2010 were identified as relevant. Those studies used 47 different instruments. This review focused in 5 instruments that concentrated the majority of the citations. Psychometric properties were acceptable.     

Pacifism and Punishment

This article seeks to expose some of the implications of certain versions of pacifism for matters of criminal punishment, arguing that the plausibility of these versions of pacifism depend on the extent to which their implicit denials of certain central punishment-related concepts are themselves reasonable.

Narrating career,positioning identity and constructing gender in an Italian adolescent's personal narratives

This article explores identity career narratives as a gendered and gendering discourse. The ‘gender differences’ approach to career development conceives of gender as a dichotomous and fixed variable influencing various aspects of career. In contrast to this mainstream approach, the paper adopts a post-structural view and reads identity and gender in terms of performativity, that is to say, constituted through the productive power of discourses. Through a detailed analysis of a text written by Giada, an adolescent involved in a career counseling project in Italy, we analyze how her career narratives implicate and constitute gender in their telling. In particular, we present the discourses that frame Giada's career narrative and we highlight how these discourses position Giada as a woman and as female. These discourses can be read as regulatory discourses: shaping and reflecting particular understandings of gender. However, we also highlight Giada's agency in questioning the regulatory practice of such discourses through linguistic acts. In the conclusions, we further explore the potential implications of these research findings for a rethinking of career counseling research and practice.     

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.
