Collaboration inflation: Egocentric source monitoring errors following collaborative remembering

Following collaborative remembering, people may adopt their partner's contributions as their own memory. In two studies, we asked people to study partially overlapping lists of words. During collaborative remembering, dyads either worked to include all words no matter who studied them or limited recall to only words studied by both dyad members. This differential focus on source information during collaborative recall impacted performance on a later source memory test. Nonetheless we found frequent source monitoring errors that displayed an egocentric bias. People were more likely to claim their partner's contributions as their own memories than attribute their memories to their partners. In collaborative remembering, people work to construct an agreed upon version of the past that quickly becomes each individual's memory.     

Hommes et aléas : appréhension des risques côtiers par des usagers et des gestionnaires de communes littorales

This study focuses on how users and managers living in coastal areas represent their living environment and how the coastal risks (erosion and flooding) are included in this place representation. To do this, a qualitative survey (semi-structured interviews) was conducted with 61 people who live in towns so-called “at risky” or “vulnerable” in relation to this issue. The interviews were fully transcribed and they have been analyzed by the Alceste textual analysis software, supplemented by a manual content analysis. For all respondents, the results highlight that coastal risks are not a major concern. For managers, the risk is taken into account but it is not usually the priority. For users, the privilege of the surrounding and the place attachment obscure the existence of risk, whatever it is.     

Contemporary patterns of career construction of a group of urban workers in São Paulo (Brazil)

By means of a qualitative approach, this study sought to understand the patterns of career construction in contemporary times through content analysis of the narratives generated by a set of 40 urban workers in São Paulo (Brazil), intentionally selected. Five narrative patterns of career construction were found and related to the existing concepts (organizational career, protean and boundaryless career, professional career, transitional career, and hybrid careers), which were respectively described by their core feature (nostalgia, possibility, enclosure, instrumentality, and hybrid). The main results showed that one quarter of participants sought career stability, continuity, and linearity (Nostalgia), one quarter sought flexibility and discontinuity (Possibility), about 1/7 sought a career based on the profession/occupation (Enclosure), about one-third constructed hybrid career narratives, and there was a frequent emergence of crises (Instrumentality). The main contribution of this study was confirming the hybrid nature of contemporary career constructions produced in a constant tension between stability and flexibility, as well as between permanence and change; nevertheless, based on collective standards.     

The relationship between social anxiety and the perception of depth-ambiguous biological motion stimuli is mediated by inhibitory ability

Orthographically projected biological motion stimuli are depth-ambiguous. Consequently, their projection when oriented towards the viewer is the same as when oriented away. Despite this, observers tend to interpret such stimuli as facing the viewer more often. Some have speculated that this facing-the-viewer bias may exist for sociobiological reasons: Mistaking another human as retreating when they are actually approaching could have more severe consequences than the opposite error. An implication of this theory is that the facing-towards percept may be perceived as more threatening than the facing-away percept. Given this, as well as the finding that anxious individuals have been found to display an attentional bias towards threatening stimuli, we reasoned that more anxious individuals might have stronger facing-the-viewer biases. Furthermore, since anxious individuals have been found to perform poorer on inhibition tasks, we hypothesized that inhibitory ability would mediate the relationship between anxiety and the facing-the-viewer bias (i.e., difficulty inhibiting the threatening percept). Exploring individual differences, we asked participants to complete anxiety questionnaires, to perform a Go/No-Go task, and then to complete a perceptual task that allowed us to assess their facing-the-viewer biases. As hypothesized, we found that both greater anxiety and weaker inhibitory ability were associated with greater facing-the-viewer biases. In addition, we found that inhibitory ability significantly mediated the relationship between anxiety and facing-the-viewer biases. Our results provide further support that the facing-the-viewer bias is sensitive to the sociobiological relevance of biological motion stimuli, and that the threat bias for ambiguous visual stimuli is mediated by inhibitory ability.     

Socially induced renal pathology of captive wild rats (Rattus villosissimus)

Long-haired rats, Rattus villosissimus, were studied in large cages. Groups of adult rats (each of 3 males, or 1 male and 2 females) were observed during intermittent encounters with a male intruder for up to 9 days. Two further groups, each of 8 males and 8 females, were maintained for 70 days without introduction of intruders. Controls were kept in small cages in which intolerant behavior was rare. Behavior during attack resembled that of male R. norvegicus, but social relationships were less stable. Only observations on males are described in detail. Some rats collapsed under attack, though unwounded, and died when not removed. Collapse occurred sometimes after a few hours, but sometimes after many days of exposure. Exposure to attack was accompanied by a decline in body weight and by some adrenal hypertrophy. Two kinds of renal pathology are described: focal glomerular hypercellularity (FGH), probably due to glomerulonephritis, and dilated distal convoluted tubules. Neither condition occurred in the controls. FGH occurred in 3 of 12 rats (25%) that remained apparently healthy during the 9 days of continuous exposure, in 21 of 23 intruders (91%) that were exposed to intermittent attack over 9 days or less without becoming debilitated, and in 8 of 11 such rats (73%) that collapsed. All rats examined from 70-day colonies had FGH, whether collapsed or not. Dilated tubules occurred in 6 of 32 intruders (19%) exposed to intermittent attack, and in 2 of 6 animals that collapsed during 70 days of exposure. Renal pathology, especially glomerulonephritis, was therefore a correlate of social intolerance; but there was no evidence that it was a significant cause of death.
