For group-living animals, it is crucial to distinguish one’s own group members from those of other groups. Studies applying
operant conditioning revealed that monkeys living in relatively small groups are able to recognize their own group members
when tested with photographs of group members and other conspecifics. Employing a simple looking time paradigm, we here show
that Barbary macaques living in two social groups comprising 46 and 57 individuals, respectively, at the enclosure ‘La Forêt
des Singes’ at Rocamadour are able to spontaneously distinguish photographs of members of their own group from those depicting
animals that belong to another group. This ability appears to develop with age, as juveniles did not discriminate between
members of their own group and another group, although they showed generally more interest in the pictures than did adults.
Juveniles frequently displayed picture directed behaviours such as lip-smacking, touching and sniffing in both conditions,
indicating that the stimuli were highly salient to them. In conclusion, it appears that at least adult monkeys are able to
memorize the faces of a large number of individuals. Whether the difference in behaviour is based on individual recognition
of one’s own group members or simply the discrimination based on familiarity remains unresolved. However, both mechanisms
would be sufficient for group membership identification. 相似文献

The current research tests the hypothesis that face processing is attuned to high-status faces. Across three experiments, faces of high-status targets were better recognized than faces of low-status targets. In Experiment 2, this memory advantage for high-status targets also extended to an attentional bias toward high-status targets and to stronger sociospatial memory (identity-location link) for high-status targets. Finally, Experiment 3 finds that high-status faces received more expert-style holistic processing than did low-status faces. This suggests that high-status faces also benefit more from the strategic deployment of expert face processing resources than low-status faces. Taken together, these data indicate that perceivers strategically allocate face processing resources to targets perceived to be high in status. 相似文献

The history of the term ambivalence documents over the last 100 years a growing diversity of meanings and applications. It suggests the understanding of the term as a ??sensitizing construct??. This view allows the formulation of an open definition which considers the interplay of different constitutional elements, namely polarization and difference, oscillation, search for meaning and agency. These elements merge into a dynamic constitution of identity or the self. Such a view can be applied to different spheres of life and is useful in different disciplines as well as professions. Ultimately at stake is the problem of human subjectivity. 相似文献

Whereas previous research has predominantly focused on dissociations between the explicit and implicit self-concepts, the current research investigates how these aspects of self-representation come into correspondence through the activation of information about the self in memory. Experiment 1 provides evidence for a “bottom-up” process of self-construal in which information activated in the implicit self-concept produces congruent changes in the explicit self-concept. Experiment 2 provides evidence for a “top-down” process of self-construal in which the motivated assertion of a propositional belief in the explicit self-concept leads, via a process of confirmatory hypothesis testing, to the activation of substantiating information in the implicit self-concept. These two processes of self-concept change are integrated within a framework that specifies how the explicit and implicit self-concepts are related within an overall, dynamic self-system. Possibilities for expanding the framework to account for self-concept dissociations are discussed. 相似文献

In situations where people (or their lawyers) seek to escape blame for wrongdoing, they often use one of two strategies: frame themselves as a hero (hero strategy) or as a victim (victim strategy). The hero strategy acknowledges wrongdoing, but highlights previous good deeds to offset blame. The victim strategy also acknowledges wrongdoing, but highlights the harms suffered by the perpetrator to deflect blame. Although commonsense suggests that past good deeds can offset blame from transgressions, moral typecasting (Gray & Wegner, 2009) suggests otherwise. Despite past good deeds, heroes remain blameworthy as moral agents. On the other hand, victims are moral patients and thus incapable of blame. Three studies found that victim strategy consistently reduced blame, while the hero strategy was at best ineffectual and at worst harmful. This effect appeared to stem from how the minds of victims and heroes are perceived. 相似文献

Patients in persistent vegetative state (PVS) may be biologically alive, but these experiments indicate that people see PVS as a state curiously more dead than dead. Experiment 1 found that PVS patients were perceived to have less mental capacity than the dead. Experiment 2 explained this effect as an outgrowth of afterlife beliefs, and the tendency to focus on the bodies of PVS patients at the expense of their minds. Experiment 3 found that PVS is also perceived as “worse” than death: people deem early death better than being in PVS. These studies suggest that people perceive the minds of PVS patients as less valuable than those of the dead – ironically, this effect is especially robust for those high in religiosity. 相似文献

Past research has implicitly assumed that only mean levels of trust and monitoring in teams are critical for explaining their interrelations and their relationships with team performance. In this article, the authors argue that it is equally important to consider the dispersion in trust and monitoring that exists within teams. The authors introduce "trust asymmetry" and "monitoring dissensus" as critical dispersion properties of trust and monitoring and hypothesize that these moderate the relationships between mean monitoring, mean trust, and team performance. Data from a cross-lagged panel study and a partially lagged study support the hypotheses. The first study also offered support for an integrative model that includes mean and dispersion levels of both trust and monitoring. Overall, the studies provide a comprehensive and clear picture of how trust and monitoring emerge and function at the team level via mean and dispersion. 相似文献

The interdependent motives of cooperation and competition are integral to adaptive social functioning. In three experiments, we provide novel evidence that both cooperation and competition goals enhance perceptual acuity for both angry and happy faces. Experiment 1 found that both cooperative and competitive motives improve perceivers?? ability to discriminate between genuine and deceptive smiles. Experiment 2 revealed that both cooperative and competitive motives improve perceivers?? perceptual sensitivity to subtle differences among happy and angry facial expressions. Finally, Experiment 3 found that the motivated increase in perceptual acuity for happy and angry expressions allows perceivers to overcome the effects of visual noise, relative to unmotivated control participants. Collectively, these results provide novel evidence that the interdependent motives of cooperation and competition can attune visual perception, accentuating the subjectively experienced signal strength of anger and happiness. 相似文献

This article provides the first comprehensive conceptual account for the imagistic mental machinery that allows us to travel through time--for the time machine in our mind. It is argued that language reveals this imagistic machine and how we use it. Findings from a range of cognitive fields are theoretically unified and a recent proposal about spatialized mental time travel is elaborated on. The following novel distinctions are offered: external versus internal viewing of time; 'watching" time versus projective 'travel" through time; optional versus obligatory mental time travel; mental time travel into anteriority or posteriority versus mental time travel into the past or future; single mental time travel versus nested dual mental time travel; mental time travel in episodic memory versus mental time travel in semantic memory; and 'seeing" versus 'sensing" mental imagery. Theoretical, empirical, and applied implications are discussed. 相似文献

Recently, two corvid species, food-caching ravens and non-caching jackdaws, have been tested in an exclusion performance (EP)
task. While the ravens chose by exclusion, the jackdaws did not. Thus, foraging behaviour may affect EP abilities. To investigate
this possibility, another food-caching corvid species, the carrion crow (Corvus corone corone), was tested in the same exclusion task. We hid food under one of two cups and subsequently lifted either both cups, or the
baited or the un-baited cup. The crows were significantly above chance when both cups were lifted or when only the baited
cup was lifted. When the empty cup was lifted, we found considerable inter-individual variation, with some birds having a
significant preference for the un-baited but manipulated cup. In a follow-up task, we always provided the birds with the full
information about the food location, but manipulated in which order they saw the hiding or the removal of food. Interestingly,
they strongly preferred the cup which was manipulated last, even if it did not contain any food. Therefore, we repeated the
first experiment but controlled for the movement of the cups. In this case, more crows found the food reliably in the un-baited
condition. We conclude that carrion crows are able to choose by exclusion, but local enhancement has a strong influence on
their performance and may overshadow potential inferential abilities. However, these findings support the hypothesis that
caching might be a key to exclusion in corvids. 相似文献
