Deactivation in the sensorimotor area during observation of a human agent performing robotic actions

It is well established that several motor areas, called the mirror-neuron system (MNS), are activated when an individual observes other’s actions. However, whether the MNS responds similarly to robotic actions compared with human actions is still controversial. The present study investigated whether and how the motor area activity is influenced by appearance (human vs. robot) and/or kinematics (human vs. robot) of the observed action using near-infrared spectroscopy. The results showed that there was a strong interaction between these factors, revealing strong deactivations in sensorimotor areas when the subject saw a human agent performing robotic actions, which was significantly different from responses when observing the human agent acting in a human way and the robot agent performing robotic actions. These results indicate that MNS activity is sensitive to congruency between the appearance and kinematics of the agent, especially when the agent has a human appearance. We discuss the experience-dependent characteristics of MNS sensitivity to observed actions.     

齐秦两国军事制度之比较

齐亡秦兴的历史命运虽由诸多因素促成,但不可否认,军事实力的差异是造成两国命运迥异的最直接原因。军事力量强弱与军事制度密不可分,军事制度是否健全、能否适应时代发展要求就成为决定一国军事实力强弱的关键,正是军事制度的差异对齐秦两国一亡一兴的最终命运产生了重要影响。     

Emotions in action through the looking glass1

Abstract: The paper aims at highlighting how our primary understanding of others’ actions is rooted in the mirror mechanism. To this end, the anatomical architecture of the mirror neuron system for action will be outlined as well as its role in grasping goals and intentions in others’ motor behaviour. One further step through the looking glass of social cognition will be referring to the ubiquitous emotional colouring of actions and considering its links with the motor domain. This will allow a clearer perspective on the mechanism underlying our abilities for emotional understanding and on cases in which these abilities are amiss, as in autistic spectrum disorders.     

Embodied cognition and health persuasion: Facilitating intention-behavior consistency via motor manipulations

The present research examines health persuasion from an embodied cognition perspective by proposing that engaging the motor system during health persuasion will lead individuals to engage in healthier behavior and have greater consistency between their intentions and behavior. In two studies, participants watched a health video while either imaging themselves performing the behavior or imaging themselves performing the behavior while also engaging their motor systems with minimal, relevant behaviors. In Study 1, after watching a flossing video, females (but not males) flossed more times in the following week after touching a floss and in Study 2, all participants (males and females) exercised more in the week after watching an exercise video while walking in place. In both experiments, participants who engaged the motor system had stronger intention-behavior consistency than those who merely imagined themselves performing the health behavior. Implications of the findings are discussed for theories of embodied cognition, intention-behavior consistency, and health persuasion.     

Between Open-minded Critical Thinking and Closed-minded Allegiance: Educational Tensions in Societies Involved in Intractable Conflict

In modern democratic societies, one of the main roles of education is to promote critical thinking and open-mindedness. However, this objective can sometimes be seen as clashing in many societies with another one of education's primary objectives—to inculcate in the younger generation a set of common values and beliefs that reinforces collective identity. The current article examines the tension between these two educational goals—fostering open-mindedness and critical-thinking skills, on the one hand, and promoting closed-minded national identity, on the other hand, in the context of intractable conflicts. In particular, we offer an analysis of the unique challenges of nurturing open-minded and critical thinking among students in the presence of processes and content common in education systems of conflict-ridden societies. These challenges are discussed in relation to the role that open-mindedness and critical thinking could play in promoting peace-building processes were they not hindered by nationalistic educational approaches designed to ensure unwavering support of the conflict.

Money for microbes—Pathogen avoidance and out‐group helping behaviour

Humans have evolved various adaptations against pathogens, including the physiological immune system. However, not all of these adaptations are physiological: the cognitive mechanisms whereby we avoid potential sources of pathogens—for example, disgust elicited by uncleanliness—can be considered as parts of a behavioural immune system (BIS). The mechanisms of BIS extend also to inter‐group relations: Pathogen cues have been shown to increase xenophobia/ethnocentrism, as people prefer to keep their societal in‐group norms unaltered and “clean.” Nonetheless, little is known how pathogen cues influence people's willingness to provide humanitarian aid to out‐group members. We examined how pathogen cues affected decisions of providing humanitarian aid in either instrumental (sending money) or non‐instrumental form (sending personnel to help, or accepting refugees), and whether these effects were moderated by individual differences in BIS sensitivity. Data were collected in two online studies (Ns: 188 and 210). When the hypothetical humanitarian crisis involved a clear risk of infection, participants with high BIS sensitivity preferred to send money rather than personnel or to accept refugees. The results suggest that pathogen cues influence BIS‐sensitive individuals' willingness to provide humanitarian aid when there is a risk of contamination to in‐group members.     

Alignment and commitment in joint action

Important work on alignment systems has been applied to philosophical work on joint action by Tollefsen and Dale. This paper builds from and expands on their work. The first aim of the paper is to spell out how the empirical research on alignment may be integrated into philosophical theories of joint action. The second aim is then to develop a successful characterization of joint action, which spells out the difference between genuine joint action and simpler forms of coordination based on alignment. I begin by introducing the empirical research and two definitions of joint action. I then argue that instead of using this research in conjunction with Searle’s account of collective intentionality, as Tollefsen and Dale suggest, we would be better served by applying this research to Gilbert’s account of plural subjects. In the final sections I distinguish between alignment, coordination, and joint action, clarify the roles of joint commitment and sub-personal alignment in joint action, and argue that these concepts are both consistent and mutually supportive. Combining these two research programs gives us an account of joint action that does justice to both the empirical and philosophical research.     

Gender stereotype–consistent memories: How system justification motivation distorts the recollection of information related to the self

Research based on system justification theory has shown that women’s self-perceptions may be altered by the motivation to justify the system and its inequalities. Self-perceptions being built on past experiences, the present study aimed to explore how system justification motivation induced through a system dependency manipulation may alter both women’s recall of autobiographical memories and their behavior. Women who were led to feel highly dependent on the social system perceived themselves as more competent and recalled memories of higher competence in the verbal domain compared with the negatively stereotyped scientific domain. Women’s behavioral choices (between doing a verbal or a math exercise) also revealed a higher preference for the gender stereotype–consistent verbal exercise in the high–system dependency condition, as compared with the low–system dependency condition. These results suggest that gender stereotypes may not only satisfy self- or group-serving motivation but also the need to perceive the system in a positive light.
