Emotion perception deficits could be due to disrupted connectivity of key nodes in the salience and emotion network (SEN), including the amygdala, subgenual anterior cingulate cortex (sgACC), and insula. We examined SEN resting-state (rs-)fMRI connectivity in rMDD in relation to Facial Emotion Perception Test (FEPT) performance. Fifty-two medication-free people ages 18 to 23 years participated. Twenty-seven had major depressive disorder (MDD) in remission (rMDD, 10 males), as MDD is associated with emotion perception deficits and alterations in rsfMRI. Twenty-five healthy controls (10 males) also participated. Participants completed the FEPT during fMRI, in addition to an 8-minute eyes-open resting-state scan. Seed regions of interest were defined in the amygdala, anterior insula and sgACC. Multiple regression analyses co-varied diagnostic group, sex and movement parameters. Emotion perception accuracy was positively associated with connectivity between amygdala seeds and regions primarily in the SEN and cognitive control network (CCN), and also the default mode network (DMN). Accuracy was also positively associated with connectivity between the sgACC seeds and other SEN regions, and the DMN, particularly for the right sgACC. Connectivity negatively associated with emotion perception was mostly with regions outside of these three networks, other than the left insula and part of the DMN. This study is the first to our knowledge to demonstrate relationships between facial emotion processing and resting-state connectivity with SEN nodes and between SEN nodes and regions located within other neural networks. 相似文献

The present study contributes to the discussion on the different components which constitute the intentionality concept about an undesired side effect, focusing on the morality and the skill. Two hundred and forty participants were asked to read a brief story about a car accident, in which it was explained the motivation of the high speed and objective and subjective skill of the agent to drive the car, and to fill in six questions about intentionality, objective risk, mental representation of risk, risk acceptance and blameworthiness for the outcome. The principal results showed that when the motivation is morally negative, people judge the side effect more intentional, also because they make more severe judgments about risk and blameworthiness. Moreover, when people are objectively proficient to perform the action (objective skill) the side effect is considered less risky and intentional and, in the case of a negative outcome, they are judged less severely than if they have a poor ability. Finally, a self-assessment of low skill to make the action (subjective skill) leads people to assess higher risks and, consequently, more intentionality for the side effect. The results are discussed on the basis of the literature about some specific components that make up the intentionality concept. 相似文献

This article aims to develop a new account of scientific explanation for computer simulations. To this end, two questions are answered: what is the explanatory relation for computer simulations? And what kind of epistemic gain should be expected? For several reasons tailored to the benefits and needs of computer simulations, these questions are better answered within the unificationist model of scientific explanation. Unlike previous efforts in the literature, I submit that the explanatory relation is between the simulation model and the results of the simulation. I also argue that our epistemic gain goes beyond the unificationist account, encompassing a practical dimension as well. 相似文献

We argue that the level of consensus about a set of social identity principles, and their perceived fundamentality, can influence the degree to which members perceive their group as an entity. This idea was explored through an experiment in which participants judged the entitativity of specific (in)groups on the basis of the distribution of the opinions held by their members about three identity-related principles that participants had previously rated for fundamentality. The results demonstrated that the more fundamental a principle was judged to be in comparison to other principles, the more important consensus about that principle was for producing group entitativity, relative to consensus about other principles. 相似文献

Køppe’s proposition of four layers in theoretical building are used here in the exploration of a specific case of eclectic combination, the use of Piagetian and Vygotskian general approaches to the analysis of proportional reasoning as a cognitive mathematical ability. It is proposed here that the eclectic consideration of these contributions depends on the consideration of their specificity, in the sense that they highlight different aspects of the phenomenon under scrutiny, and also on the consideration of the coherence between this eclectic convergence and premises in terms of schools of thought under which each contribution is framed. We conclude proposing in accordance to S. Køppe’s proposal that eclecticism can be valuable and heuristic in theory development, but this contribution will depend largely on the effort in establishing careful relations between the four layers of theory-building. 相似文献

Traditionally, an enthymeme is an incomplete argument, made so by the absence of one or more of its constituent statements.
An enthymeme resolution strategy is a set of procedures for finding those missing elements, thus reconstructing the enthymemes
and restoring its meaning. It is widely held that a condition on the adequacy of such procedures is that statements restored
to an enthymeme produce an argument that is good in some given respect in relation to which the enthymeme itself is bad. In
previous work, we emphasized the role of parsimony in enthymeme resolution strategies and concomitantly downplayed the role
of “charity”. In the present paper, we take the analysis of enthymemes a step further. We will propose that if the pragmatic
features that attend the phenomenon of enthymematic communication are duly heeded, the very idea of reconstructing enthymemes loses much of its rationale, and their interpretation comes to
be conceived in a new light. 相似文献

Endocannabinoids (eCBs) modulate a variety of brain functions via activation of the widely expressed CB1 receptor. One site of high density of this receptor is the basolateral amygdala (BLA), a structure involved in the formation of aversive memories. The activation and blockade of CB1 receptors by systemic or hippocampal drug administrations have been shown to modify memory processing. However, little is known about the role of the BLA endocannabinoid system in aversive memories. Additionally, BLA endocannabinoid transmission seems to be related to emotional states, but the relevance of these effects to memory formation is still unknown. In this study we investigated the effects of the eCB anandamide (AEA) and the CB1 antagonist/inverse agonist AM251 infused into the BLA on the acquisition of an aversive memory task, concomitantly evaluating basal anxiety levels in rats. Male rats received pre-training micro-injection of AEA, AM251 or vehicle bilaterally into the BLA, and were studied with the plus-maze discriminative avoidance task (a paradigm that allows concomitant and independent evaluation of anxiety-like behavior and the memory of an aversive task). Our results showed that AEA into the BLA before training prevented memory retrieval 24 h later, as evaluated by exploration of the aversive arm of the maze, while AM251 into the BLA did not interfere with animals' performance. In addition, AEA had no effect on anxiety-like behavior (as evaluated by open arm exploration and risk assessment), while AM251 induced an anxiogenic effect. Our data indicate an important role of BLA CB1 receptors in aversive memory formation, and suggest that this involvement is not necessarily related to a possible modulation of anxiety states. 相似文献

Two studies were conducted with college students to validate the Spanish-language version of the "Acceptance of Modern Myths about Sexual Aggression" scale (AMMSA) (Gerger, Kley, Bohner & Siebler, 2007). This scale assesses modern myths about sexual aggression in a subtle way. In Study 1, 305 students completed the Spanish AMMSA and other scales with related content. In Study 2, 263 participants completed the Spanish AMMSA and answered questions about a hypothetical sexual assault perpetrated by a young man against a female acquaintance. The Spanish AMMSA showed high internal consistency and adequate evidence of validity in both studies. Compared to traditional scales of rape myth acceptance, mean scores on the AMMSA were higher and their distributions more closely approximated normality. These findings suggest that the Spanish version of the AMMSA scale is a useful instrument to study the social perception of sexual aggression. 相似文献

This paper provides an analytical model representing four polar ethical approaches drawn from the main ethical positions suggested
by the philosophical, psychological, and socio-economic literature. Moreover, it develops the model in order to obtain rankings
of the four approaches in terms of happiness and, consequently, to provide insights into which ethical approach should best
be adopted by each individual, according to his characteristics (income level, in developed countries (DCs) or in less developed
countries (LDCs), aspiration level): some dynamics are also predicted, if the Golden and the Copper Rules are applied. Finally,
this paper provides insights into which ethical approach should best be adopted by each society, according to its characteristics
(DCs or LDCs, social distribution of aspiration levels), by predicting happiness levels in alternative countries, according
to the prevailing ethics, and by comparing these predictions with the observed happiness levels, thus providing an empirical
test of the analytical model: some dynamics are again predicted, with non-Protestant DCs moving to higher, and Protestant
DCs towards lower, happiness levels (conditioned to the per capita income), due to the increasing and decreasing rejection
of the Golden and Copper Rules, respectively, and with LDCs moving to lower (conditioned to the increasing per capita income)
in the short-run and higher happiness levels in the long run, by establishing and entertaining conditions that set clear incentives
for moral behaviour, in order to increase and decrease the adoption of the Golden and Copper Rules, respectively. 相似文献
