Reorganization of functional and effective connectivity during real-time fMRI-BCI modulation of prosody processing

Mechanisms of cortical reorganization underlying the enhancement of speech processing have been poorly investigated. In the present study, we addressed changes in functional and effective connectivity induced in subjects who learned to deliberately increase activation in the right inferior frontal gyrus (rIFG), and improved their ability to identify emotional intonations by using a real-time fMRI Brain-Computer Interface. At the beginning of their training process, we observed a massive connectivity of the rIFG to a widespread network of frontal and temporal areas, which decreased and lateralized to the right hemisphere with practice. Volitional control of activation strengthened connectivity of this brain region to the right prefrontal cortex, whereas training increased its connectivity to bilateral precentral gyri. These findings suggest that changes of connectivity in a functionally specific manner play an important role in the enhancement of speech processing. Also, these findings support previous accounts suggesting that motor circuits play a role in the comprehension of speech.     

Evidence for right hemisphere phonology in a backward masking task

The extent to which orthographic and phonological processes are available during the initial moments of word recognition within each hemisphere is under specified, particularly for the right hemisphere. Few studies have investigated whether each hemisphere uses orthography and phonology under constraints that restrict the viewing time of words and reduce overt phonological demands. The current study used backward masking in the divided visual field paradigm to explore hemisphere differences in the availability of orthographic and phonological word recognition processes. A 20 ms and 60 ms SOA were used to track the time course of how these processes develop during pre-lexical moments of word recognition. Nonword masks varied in similarity to the target words such that there were four types: orthographically and phonologically similar, orthographically but not phonologically similar, phonologically but not orthographically similar and unrelated. The results showed the left hemisphere has access to both orthography and phonology early in the word recognition process. With more time to process the stimulus, the left hemisphere is able to use phonology which benefits word recognition to a larger extent than orthography. The right hemisphere also demonstrates access to both orthography and phonology in the initial moments of word recognition, however, orthographic similarity improves word recognition to a greater extent than phonological similarity.     

Ethical Lessons from Heidegger’s Phenomenological Reading of Kant’s Practical Philosophy: Heideggerian Revision of Kant’s Justification of Morality*

ABSTRACT

In The Essence of Human Freedom, Heidegger suggests that Kant’s idea of pure will and Heidegger’s own idea of resoluteness are rooted in the same experience of demand from our own essence. This experience can unfold, I argue, through twofold self-understanding: first, the primordial self-understanding on the existentiell level that results in the indefiniteness of pure will (or resoluteness), as Heidegger’s phenomenological reading of Kant (or his own existential analysis) presents; and second, the practical self-understanding on the rational level that results in the principle of morality, as Kant’s Groundwork of the Metaphysics of Morals demonstrates. Based on this approach, if we accept Heidegger’s phenomenological interpretation of pure will but do not follow his rejection of the categorical imperative formulas, we can achieve a Heideggerian revision of Kant’s original justification of morality while avoiding Kant’s problematic assumption that the authentic self belongs to the intelligible realm.     

Empathy and humanitarianism predict preferential moral responsiveness to in-groups and out-groups

ABSTRACT

The current research tests whether empathy—sharing others’ emotions—and humanitarianism—recognizing the moral worth of all people—each predict moral responsiveness toward others but in ways that favor in-groups and out-groups, respectively. In Studies 1 and 2, empathy and humanitarianism differentially predicted preferential moral concern for in-groups and out-groups. In Study 3, humanitarianism predicted lower in-group-targeted prosociality and greater out-group prosociality. In Study 4, empathy and humanitarianism predicted perceived moral obligation to in-groups and out-groups respectively. In Study 5, out-group obligation mediated between humanitarianism and allocations to out-group charities, and in-group obligation mediated between empathy and one of two in-group charities. In sum, empathy and humanitarianism are associated with preferential morality via group-based obligation, suggesting that morality could be extended by altering empathy, humanitarianism, or group processes.     

Main and Moderated Effects of Moral Cognition and Status on Bullying and Defending

This study analyzed the relations of two dimensions of moral cognition (i.e., acceptance of moral transgression and moral disengagement) and two forms of status in the peer group (i.e., social preference and perceived popularity) with bullying and defending among 235 primary‐school children and 305 middle‐school early adolescents. Social status was tested as a moderator of the associations between moral cognition and bullying and defending. Participants completed self‐reports assessing the two dimensions of moral cognition and peer nominations for status, bullying, and defending. Both acceptance of moral transgression and moral disengagement were associated to bullying among early adolescents only, whereas in childhood moral disengagement was linked to defending among girls. Social status moderated the associations between morality dimensions and bullying and defending. The moderating effects of status were discussed considering status as a magnifying lens for the relations between individual characteristics and social behavior. The results were also discussed with reference to age and gender differences in the associations. Aggr. Behav. 38:456‐468, 2012. © 2012 Wiley Periodicals, Inc.     

How Can We Study Heroism? Integrating Persons,Situations and Communities

Heroism—an individual's commitment to a noble purpose, usually aimed at furthering the welfare of others, and involving the willingness to accept the consequences of achieving that purpose—has received little attention from political psychologists, even though a person is arguably as liable to act heroically as she is to act in a morally reprehensible manner. Specifically, important questions remain in how heroes can be identified beforehand and how such behavior can be successfully studied and promoted. We posit that recent work in genocide studies, positive psychology, personality psychology, ecological psychology, and moral psychology provides new and promising directions for better understanding heroic behavior. These developments can provide the tools for understanding the complex interplay of factors—including traits, situations, and communal beliefs—motivating heroic behavior.     

论民族道德与国家道德

在民族国家特别是多民族国家中,如何看待并处理好民族道德与国家道德的关系,是一个事关民族利益和国家利益的大问题。从民族道德与国家道德的关系看,民族道德统一于国家道德,民族利己主义是为国家道德所不容的,民族道德与国家道德的最高原则是无产阶级国际主义。必须用前瞻性的战略眼光来看待并认识这一问题,因为它事关民族与国家的长远利益,对构建和谐民族、和谐国家、和谐社会均具有重要的理论意义和现实意义。     

论道德内化的心理机制及其特征

所谓道德内化,是指个体在后天的社会生活和实践中,经过一定方式的社会学习,接受社会的道德教化,将社会的道德原则、规范和要求转化为其自身的道德需要,形成其自身稳定的道德人格特质和道德行为反应模式的过程。道德内化的心理机制是道德主体的自我意识,它一般由“由我是什么”、“我应当成为什么”和“我必须成为什么”三个逻辑环节组成。道德内化具有他律性和自律性相统一、平衡性和失衡性相统一、共同性和差异性相统一、阶段性和整体性相统一等特点。     

Comparing the facets of the big two in global evaluation of self versus other people

The Big Two of agency and communion can be divided into the facets of agency-assertiveness, agency-competence, communion-morality, and communion-warmth. The present research studies how these facets are related to global evaluation of self versus others. In five studies we tested whether self-evaluation is reliably related to agency-assertiveness (H1), and evaluation of others to communion-morality (H2). Participants had to describe themselves (or a specific other person) on the facets and later to rate their self-evaluation (or other-evaluation). Supporting hypotheses, Studies 1, 3, and 4 showed that agency-assertiveness was reliably related to self-evaluation (Study 4: also agency-competence). Studies 2–5 showed that communion-morality was reliably related to evaluation of an acquaintance, but agency-competence (Studies 3 and 5) and communion-warmth (Study 2) were also important. We conclude that supporting H1, agency-assertiveness is particularly important for self-evaluation, whereas partly supporting H2, evaluation of others is associated with communion-morality, but also agency-competence and communion-warmth.
