In most Western societies, wealth inequality is increasing, which in turn could increase people’s belief that one’s standing is relatively disadvantaged. Based on relative deprivation theory, we argue that such an experience of personal relative deprivation should causally lead to greater interpersonal hostility. Indeed, three experiments show that participants in a personal relative deprivation condition reported higher levels of aggressive affect and behaved more aggressively than participants in a personal relative gratification condition. Compared to a control condition, participants experiencing personal relative deprivation were more aggressive rather than participants experiencing personal relative gratification being less aggressive. However, personal relative deprivation increased aggressive behavior only toward targets that were the source for participants’ experience of disadvantage, but it did not increase aggression toward neutral targets. 相似文献
Perceptual attention in healthy participants is characterized by two biases, one operating in the horizontal plane, which draws attention leftward, and the other operating in the vertical plane, which draws attention upward. Given that these biases are reliably found in the same individual, and appear similar at a surface level, a number of researchers have investigated the relationship between horizontal and vertical attentional biases. To date, these investigations have failed to find an association, and this may be due to the fact that one-dimensional vertical and horizontal stimuli were presented separately rather than being measured from a single, two-dimensional stimulus. Across three experiments, two dimensional stimuli were presented, and participants marked the centre of the stimuli. In addition, the shapes of the stimuli were manipulated to determine whether this produced the same modulation of the two biases. Across 13 stimuli and three experiments there were no correlations between the vertical and horizontal biases. In addition, manipulations of stimulus shape, which affected biases in one dimension, did not affect biases in the other dimension. There were, however, consistent correlations between the degree of bias within each dimension across the different stimuli. This study has produced converging evidence that horizontal and vertical biases in spatial judgments rely on separate cognitive mechanisms. To account for these results we discuss a model whereby horizontal asymmetries rely more on space-based mechanisms whereas vertical asymmetries rely more on object-based mechanisms. 相似文献
This paper asks whether persistence can be a matter of convention. It argues that in a rather unexciting de dicto sense persistence
is indeed a matter of convention, but it rejects the notion that persistence can be a matter of convention in a more substantial
de re sense. However, scenarios can be imagined that appear to involve conventional persistence of the latter kind. Since
there are strong reasons for thinking that such conventionality is impossible, it is desirable that our metaphysical-cum-semantic
theories of persistence be able to account for such scenarios in terms of conventions of the first kind. Later parts of the
article therefore investigate whether three of the currently most influential metaphysical-cum-semantic theories of persistence—the
endurance theory, the stage theory, and the perdurance theory—can do this. Fortunately, for them, it turns out that all can,
though some philosophers have disputed this. However, when we ask how they account for a typical case of “conventional persistence”
some problematic features of the theories—having to do with reference, persistence conditions, how they relate, and the epistemology
of persistence—are revealed. 相似文献
Negative emotional stimuli activate a broad network of brain regions, including the medial prefrontal (mPFC) and anterior cingulate (ACC) cortices. An early influential view dichotomized these regions into dorsal-caudal cognitive and ventral-rostral affective subdivisions. In this review, we examine a wealth of recent research on negative emotions in animals and humans, using the example of fear or anxiety, and conclude that, contrary to the traditional dichotomy, both subdivisions make key contributions to emotional processing. Specifically, dorsal-caudal regions of the ACC and mPFC are involved in appraisal and expression of negative emotion, whereas ventral-rostral portions of the ACC and mPFC have a regulatory role with respect to limbic regions involved in generating emotional responses. Moreover, this new framework is broadly consistent with emerging data on other negative and positive emotions. 相似文献
This study investigated the impact of emotion expectancies on adolescents’ moral decision making in hypothetical situations. The sample consisted of 160 participants from three different grade levels (mean age = 15.79 years, SD = 2.96). Participants were confronted with a set of scenarios that described various emotional outcomes of (im)moral actions and needed to decide what they would do if they were in the protagonist’s shoes. Findings demonstrate that emotion expectancies differentially influenced adolescents’ hypothetical decision making in antisocial versus prosocial behavioral contexts. Whereas negatively charged self-evaluative emotions over failing to act morally (e.g., guilt) were the strongest predictor for moral choice in antisocial behavioral contexts, positively charged self-evaluative emotions over acting morally (e.g., pride) most strongly predicted moral choice in prosocial contexts. Older adolescents paid greater attention to outcome-oriented emotions that make the decision to act morally less attractive (e.g., regret). Overall, the study suggests that emotion expectancies influence moral decision making in unique and meaningful ways. 相似文献
The integration of spatial information perceived from different viewpoints is a frequent, yet largely unexplored, cognitive
ability. In two experiments, participants saw two presentations, each consisting of three targets—that is, illuminated tiles
on the floor—before walking the shortest possible path across all targets. In Experiment 1, participants viewed the targets either from the same viewpoint or from different viewpoints. Errors in recalling targets
increased if participants changed their viewpoints between presentations, suggesting that memory acquired from different viewpoints
had to be aligned for integration. Furthermore, the error pattern indicates that memory for the first presentation was transformed
into the reference frame of the second presentation. In Experiment 2, we examined whether this transformation occurred because new information was integrated already during encoding or because
memorized information was integrated when required. Results suggest that the latter is the case. This might serve as a strategy
for avoiding additional alignments. 相似文献
Past research has provided abundant evidence that playing violent video games increases aggressive behavior. So far, these effects have been explained mainly as the result of priming existing knowledge structures. The research reported here examined the role of denying humanness to other people in accounting for the effect that playing a violent video game has on aggressive behavior. In two experiments, we found that playing violent video games increased dehumanization, which in turn evoked aggressive behavior. Thus, it appears that video-game-induced aggressive behavior is triggered when victimizers perceive the victim to be less human. 相似文献
In classroom teaching, material objects like the blackboard play an important role. Yet qualitative research on education
has largely ignored this material dimension of education and focused on interaction and discourse. Both dimensions are, however,
closely related to each other. Material objects are embedded in classroom discourse and are transformed into knowledge objects
by speech acts, and in turn structure discussions and constitute a point of reference for school lessons. Drawing on ethnographic
research on classroom lessons in mathematics and science classes in German high schools, we propose a perspective that recognizes
both the materiality of teaching and its interactive dimension. 相似文献
We discuss various implications of some radical anti-representationalist views of cognition and what they have to offer with regard to the naturalization of intentionality and the explanation of cognitive phenomena. Our focus is on recent arguments from proponents of enactive views of cognition to the effect that basic cognition is intentional but not representational and that cognition is co-extensive with life. We focus on lower rather than higher forms of cognition, namely the question regarding the intentional and representational nature of cognition found in organisms simpler than human beings, because enactivists do not deny that more sophisticated cognitive phenomena are representational and involve content. After introducing the debate on the naturalization of intentionality (Sect. 2), we briefly review different varieties of enactivism and introduce their central claims (Sect. 3). In Sect. 4 we turn to radical enactivism in order to focus on the arguments for a thoroughly non-representational, enactive account of perception and basic cognition. In particular, we discuss three major issues: First, what is supposed to replace the representational analysis of perception in a radical-enactive explanation of perception? How does the enactive explanation of perception compare to the best scientific work on the neuroscience of perception? Second, what is—on an enactive account—the function of neural processing in the brain for the generation of perception if not to produce representations? This question is especially pressing since one implication of autopoietic enactivism (accepted by radical enactivists) is that even the simplest organisms, i.e. single-celled organisms, have cognitive capacities (Sect. 5). Since they lack brains and nervous systems, enactivists must specify the (possibly) unique contribution of the brain and nervous system in those animals who have them. In Sect. 5, we evaluate the advantages of an autopoietic–enactive approach to the naturalization of intentionality and end with a suggestion how cognition may relate to intentionality and representation.
Today plant-based alternatives to animal-agricultural products are made available or developed alongside ‘cultured’ meat, and products utilising genetic modification. To proponents, this signifies the emergence of ‘cellular agriculture’ as a food-production field or the possibility of a ‘post-animal bioeconomy’: a way to safely and sustainably produce animal products without animals. Drawing on previous work on ontological politics enables acknowledging how these novel objects unsettle animal products’ ontological stability, thereby offering a practical case of how the world is multiply produced. An important emphasis within this tradition is the situated nature of reality-making practices. Consequently our analysis, focusing on different practices, sites and objects compared to influential studies of ontological politics, necessitates bringing in hitherto relatively unexplored political-economic relations and legal processes. As global processes and problem formulations, laboratories, and national or regional regulations come together to remake realities the ontological-political dynamics determining the fate of cellular agriculture or a post-animal bioeconomy becomes shaped by a combination of conflicts and budding collaborations between proponents of new technologies and established livestock interests. Understanding these dynamics requires tracing both how post-animal products reshape the world they are introduced into, and acknowledging the friction evident as reality-carrying objects leave their laboratories. 相似文献
