Do self‐presentation concerns moderate the relationship between implicit and explicit homonegativity measures?

This study investigated whether the relation between implicit and explicit homonegativity measures is affected by self-presentation concerns, since previous research in this area has been inconclusive. In Experiment 1, 70 high-school students made evaluative ratings of pictures of homosexual and heterosexual couples. Self-presentation was manipulated by either instructing participants that the study concerned attitudes regarding sexual orientation (socially sensitive) or attitudes regarding age (less sensitive). The age-instruction led to increased homonegativity but not to a stronger correlation with an Implicit Association Test (IAT; Greenwald, McGhee & Schwartz, 1998) with homo/heterosexual couples. Concerns regarding the construct validity of the present implementation of the IAT were alleviated in Experiment 2, where heterosexual (n= 30) but not homosexual (n= 30) participants showed implicit homonegativity. The current findings are problematic for the interpretation of low correspondence between implicit and explicit attitude measures as being primarily an effect of self-presentation concerns.     

Comparing the EthoVision 2.3 system and a new computerized multitracking prototype system to measure the swimming behavior in fry fish

Coming from the framework of unmarked fry tracking, we compared the capacities, advantages, and disadvantages of two recent video tracking systems: EthoVision 2.3 and a new prototype of multitracking. The EthoVision system has proved to be impressive for tracking a fry using the detection by gray scaling. Detection by subtraction has given less accurate results. Our video multitracking system is able to detect and track more than 100 unmarked fish by gray scaling technique. It permits an analysis at the group level as well as at the individual level. The multitracking program is able to attribute a number to each fish and to follow each one for the whole duration of the track. Our system permits the analysis of the movement of each individual, even if the trajectories of two fish cross each other. This is possible thanks to the theoretical estimation of the trajectory of each fish, which can be compared with the real trajectory (analysis with feedback). However, the period of the track is limited for our system (about 1 min), whereas EthoVision is able to track for numerous hours. In spite of these limitations, these two systems allow an almost continuous automatic sampling of the movement behaviors during the track.     

Sensory sensitivity after acquired brain injury: A systematic review

Patients with acquired brain injury frequently report experiencing sensory stimuli as abnormally under- (sensory hyposensitivity) or overwhelming (sensory hypersensitivity). Although they can negatively impact daily functioning, these symptoms are poorly understood. To provide an overview of the current evidence on atypical sensory sensitivity after acquired brain injury, we conducted a systematic literature review. The primary aim of the review was to investigate the behavioural and neural mechanisms that are associated with self-reported sensory sensitivity. Studies were included when they studied sensory sensitivity in acquired brain injury populations, and excluded when they were not written in English, consisted of non-empirical research, did not study human subjects, studied pain, related sensory sensitivity to peripheral injury or studied patients with a neurodegenerative disorder, meningitis, encephalitis or a brain tumour. The Web of Science, PubMed and Scopus databases were searched for appropriate studies. A qualitative synthesis of the results of the 81 studies that were included suggests that abnormal sensory thresholds and a reduced information processing speed are candidate behavioural mechanisms of atypical subjective sensory sensitivity after acquired brain injury. Furthermore, there was evidence for an association between subjective sensory sensitivity and structural grey or white matter abnormalities, and to functional abnormalities in sensory cortices. However, further research is needed to explore the causation of atypical sensory sensitivity. In addition, there is a need for the development of adequate diagnostic tools. This can significantly advance the quantity and quality of research on the prevalence, aetiology, prognosis and treatment of these symptoms.     

Systematic mapping of developmental milestones in wild chimpanzees

Postnatal development is protracted relative to lifespan in many primates, including modern humans (Homo sapiens), facilitating the acquisition of key motor, communication and social skills that can maximize fitness later in life. Nevertheless, it remains unclear what evolutionary drivers led to extended immature periods. While the developmental milestone literature is well established in humans, insight we can gain from one‐species models is limited. By comparing the timing of relatable developmental milestones in a closely related species, the chimpanzee (Pan troglodytes), we can gain further understanding of the evolution of such an extended developmental phase. To date, few studies have specifically attempted to estimate developmental milestones in a manner comparable to the human literature, and existing studies lack sufficient sample sizes to estimate which milestones are more plastic with higher inter‐individual variation in the timing of their emergence. Here, we describe the emergence of gross motor, fine motor, social interaction and communication traits from a longitudinal sample of 19 wild chimpanzee infants (8 females and 11 males), Taï National Park, Côte d’Ivoire. Gross motor traits emerged at a mean of 4 months, communication traits at 12 months, social interaction traits at 14 months and fine motor traits at 15 months, with later emerging milestones demonstrating greater inter‐individual variation in the timing of the emergence. This pattern of milestone emergence is broadly comparable to observations in humans, suggesting selection for a prolonged infantile phase and that sustained skills development has a deep evolutionary history, with implications for theories on primate brain development.     

Religious Conflict and the Chain of Command in the American and French Militaries

Analyzing characteristics of the organizational environment, the organization, and its actors recommended by the framework guiding this symposium on the cross‐cultural study of religion in public institutions, we identify common elements of military organization that shape local and national policies surrounding religion cross‐nationally. Comparison of cases from U.S. and French militaries—a secularist group at the U.S. Air Force Academy, and Muslim soldiers in France—demonstrates this framework's utility by directing attention to when, how, and by what logics constitutional protections are afforded to religious (and nonreligious) minorities. This analysis also reveals two additional arenas of investigation important to the study of religion in public institutions. Because religion today is often at the center of disputes over citizens’ conflicting rights, conflicts over religion in the military, and in other public institutions, demand special attention. In addition, our cases call attention to the importance of organizational structures and authority. Military settings make this point obvious, since the chain of command plays a fundamental and powerful role in the operation of militaries cross‐nationally—including in activities and policies surrounding religion and religious groups.     

The impact of rewards on empathic accuracy and emotional mimicry

The notion that motivation influences empathic accuracy has been inferred from aspects of the task, the situation or the relationship between interaction partners or between groups. The present research assessed whether monetary reward influences cognitive and affective empathy. In Study 1, cognitive empathy was assessed for 42 participants who decoded briefly (33 ms) presented expressions of sadness and anger. For half the participants, correctly decoded expressions on male faces were rewarded, for the other half correctly decoded expressions on female faces were rewarded. The results showed that rewards increase empathic accuracy for both emotions equally. In Study 2, facial EMG was measured as well to assess emotional mimicry as an index of affective empathy. Study 2 replicated the findings from Study 1 and found a moderation of affective empathy as indexed through facial mimicry for sadness. Thus, simple monetary rewards affect both cognitive and affective empathy.     

A cognitive-based model of tool use in normal aging

While several cognitive domains have been widely investigated in the field of aging, the age-related effects on tool use are still an open issue and hardly any studies on tool use and aging is available. A significant body of literature has indicated that tool use skills might be supported by at least two different types of knowledge, namely, mechanical knowledge and semantic knowledge. However, neither the contribution of these kinds of knowledge to familiar tool use, nor the effects of aging on mechanical and semantic knowledge have been explored in normal aging. The aim of the present study was to fill this gap. To do so, 98 healthy elderly adults were presented with three tasks: a classical, familiar tool use task, a novel tool use task assessing mechanical knowledge, and a picture matching task assessing semantic knowledge. The results showed that aging has a negative impact on tool use tasks and on knowledge supporting tool use skills. We also found that aging did not impact mechanical and semantic knowledge in the same way, confirming the distinct nature of those forms of knowledge. Finally, our results stressed that mechanical and semantic knowledge are both involved in the ability to use familiar tools.     

The effects of cystic fibrosis on couples: marital satisfaction, emotions, and coping strategies

An earlier diagnosis and better overall multidisciplinary care enable people suffering from Cystic Fibrosis (CF) to have a life expectancy of 40. Consequently, new populations and questions about the development of the life of couples have arisen. This study by questionnaires takes a first look at marital adjustment, anxiety, depression, and emotion focused, social support focused, and problem focused coping strategies in 16 CF patients and their partners. As a whole, the couples' marital adjustment level was good; it was higher for men who were patients than men who were partners, and vice versa for women. Anxiety was high for at least one partner in 10 of the couples; depression, for at least one partner in seven of them. The participants seem to use coping strategies to a lesser extent than the general population. The results are discussed in terms of how the quality of life as a couple with one partner suffering from CF is affected by the proper mutual adjustment of the partners.
