Faces have features characteristic of the identity, age and sex of an individual. In the context of social communication and
social recognition in various animal species, facial information is relevant for discriminating between familiar and unfamiliar
individuals. Here, we present two experiments aimed at testing the ability of cattle (Bos taurus) to visually discriminate between heads (including face views) of familiar and unfamiliar conspecifics represented as 2D
images. In the first experiment, we observed the spontaneous behaviour of heifers when images of familiar and unfamiliar conspecifics
were simultaneously presented. Our results show that heifers were more attracted towards the image of a familiar conspecific
(i.e., it was chosen first, explored more, and given more attention) than towards the image of an unfamiliar one. In the second
experiment, the ability to discriminate between images of familiar and unfamiliar conspecifics was tested using a food-rewarded
instrumental conditioning procedure. Eight out of the nine heifers succeeded in discriminating between images of familiar
and unfamiliar conspecifics and in generalizing on the first trial to a new pair of images of familiar and unfamiliar conspecifics,
suggesting a categorization process of familiar versus unfamiliar conspecifics in cattle. Results of the first experiment
and the observation of ear postures during the learning process, which was used as an index of the emotional state, provided
information on picture processing in cattle and lead us to conclude that images of conspecifics were treated as representations
of real individuals. 相似文献

The degree of accuracy with which physicians understand their patients' views may be of central importance for promoting self-care in the majority of chronic illnesses and in type 2 diabetes in particular. The objectives of this study were to measure the accuracy of the general practitioners' understanding of the patients' views and relate it to health behavioural outcomes in patients with non-complicated type 2 diabetes. The participants in this cross-sectional study consisted of 14 clinicians and 78 of their patients from Paris, France. The predictors were levels of accuracy in understanding the patients' views derived from the illness perception questionnaire-revised (IPQ-R). The outcomes were patient-reported self-care measures. In regression models controlling for clinical and personal variables, higher accuracy on chronicity beliefs was associated with an improved diet and increased blood glucose self-testing and higher accuracy in identifying treatment control beliefs was associated with better dietary self-care. Accuracy was higher with regard to beliefs about causes, treatment control and consequences. These results suggest that accuracy may impact self-care in specific domains of illness perception but not others. The results may help identify useful avenues of communication training designed for professionals. 相似文献

According to terror management theory, heightened concerns about mortality should intensify the appeal of charismatic leaders. To assess this idea, we investigated how thoughts about death and the 9/11 terrorist attacks influence Americans' attitudes toward current U.S. President George W. Bush. Study 1 found that reminding people of their own mortality (mortality salience) increased support for Bush and his counterterrorism policies. Study 2 demonstrated that subliminal exposure to 9/11-related stimuli brought death-related thoughts closer to consciousness. Study 3 showed that reminders of both mortality and 9/11 increased support for Bush. In Study 4, mortality salience led participants to become more favorable toward Bush and voting for him in the upcoming election but less favorable toward Presidential candidate John Kerry and voting for him. Discussion focused on the role of terror management processes in allegiance to charismatic leaders and political decision making. 相似文献

Pre-test exposure to training-related cues is known to improve subsequent retention performance. To identify brain regions engaged in processes promoted by retrieval cues, a brain imaging approach using the [6-14C]glucose autoradiographic technique was used. Sprague-Dawley rats trained in a brightness discrimination avoidance task were submitted to different cueing conditions after a 1- or a 21-day training-to-test interval (TTI). Animals were either non-cued, cued with a box, or cued with a box and the light that served as a discriminative stimulus. Effects of the different cueing conditions on retention performance or on metabolic activity in 58 different brain regions were investigated. Rats cued with the light exhibited a subsequent improvement of their retention performance relative to controls, when tested at the 1- but not 21-days TTI, confirming our previous results. At the 1-day retention interval, a comparison between rats cued with the box and rats cued with the box and the light showed that the light cue significantly increased glucose uptake in a neuronal network composed of the lateral, basal, and central nuclei of the amygdala, the anterior and suprachiasmatic hypothalamic nuclei, the nucleus accumbens, the medial septum, and the insular cortex. In contrast, at the 21-day retention interval, both groups demonstrated similar cerebral metabolic activity. The present results indicate that exposure to a light cue increased metabolic activity in the previously mentioned brain structures only when the light acted as an effective retrieval cue, suggesting an involvement of this network in the processes triggered by a retrieval cue. Arguments are provided supporting the notion that the amygdala may play a key role in these processes. Whether the amygdala is a part of a neural network involved in retrieval processes or in neuromodulating systems that favour the efficacy of retrieval processes is also discussed. 相似文献

The aim of this study was to investigate the multidimensional nature of authentic leadership (AL) through the re-evaluation of the factor structure of the most commonly used scales in AL research, the Authentic Leadership Questionnaire (ALQ) and the Authentic Leadership Inventory (ALI). Results from Exploratory Structural Equation Modeling (ESEM) conducted among 538 workers of private (57,81%) and public (42,19%)? organizations provide support for the multidimensional nature of AL but also reveal excessive content overlap across subscales and an inability to properly reflect the a priori factor structure of both instruments. Further analyses enabled the identification of key items from both instruments providing a cleaner depiction of the a priori dimensionality of AL, leading to the development of an integrated optimized measure, the Authentic Leadership Integrated Questionnaire (AL-IQ). The main contribution of this study is the proposition of an alternative and optimized measure of authentic leadership that sheds light on the distinct theoretical facets of this positive leadership style. Our data suggest that the AL-IQ is a promising tool for characterizing the strengths and weaknesses of leaders and managers’ AL practices. To our knowledge, this is the first study to use a combination of classical Confirmatory Factor Analyses (CFA) and newly developed ESEM framework to assess the construct validity (factor structure, reliability, and criterion-related validity) of the two main AL measures: the ALQ and the ALI. 相似文献

Research in developmental psychopathology has long been preoccupied with rather broad categories of behavior, but we know little about the specific behaviors that comprise these categories. The objective of this study was to: (a) estimate the prevalence of problem and social competence behaviors in the general population of children at 17 months of age, and (b) describe the continuity and discontinuity in the degree to which children exhibit these behaviors between 17 and 29 months of age. The results show that frequent problem behaviors are not typical of children under two years of age. Further, the results suggest that it is possible to distinguish between different types of problem behaviors before two years of age. In addition, the results show that gender differences in some problem behaviors are already present before two years of age, and increase in magnitude during toddlerhood. Finally, the results show that interindividual differences in problem behaviors observed before two years of age are stable. The predictive accuracy of frequent problem behaviors in children at 17 months of age was limited, however, with often a majority of toddlers not behaving this way a year later. Overall, our results suggest that toddlerhood represents a critical period when behavioral and emotional problems of potentially clinical significance emerge. Pediatricians should routinely ask parents to report the frequency of their young children's problem behaviors during child health supervision visits so that children whose frequent problem behaviors persist over time can be identified and possibly referred for treatment. 相似文献
