Effects of Right- and Left-Hemisphere Damage on Understanding Conversational Implicatures

Processing of implicatures was examined in 27 right-brain-damaged (RBD) and 31 left-brain-damaged (LBD) stroke patients with focal lesions using a new implicatures battery (IB) as part of an exploration of the neural basis and modularity of natural language pragmatics. Following Grice, we sampled implicatures of Quantity, Quality, Relation, and Manner. Verbal implicatures consisted of two-sentence conversational vignettes which are literally problematic. Nonverbal implicatures consisted mostly of famous paintings that are literally problematic (e.g., Magritte's "Le Domain d'Arnheim"). The patient has to identify and solve the problem. To compare with performance on the IB, patients also received a Hebrew adaptation of Gardner and Brownell's Right Hemisphere Communication Battery, a new test of basic speech acts (verbal and nonverbal assertions, questions, requests, and commands), a Hebrew version of the Western Aphasia Battery, and standardized neuropsychological tests. Both LBD and RBD patients were significantly impaired in implicature processing relative to age-matched normal controls. In general, both patient groups showed weak correlations of implicatures with extents of lesions in left perisylvian language area or its right-hemisphere (RH) homolog. However, performance of LBD and RBD patients on the IB revealed different patterns of correlations with other pragmatic, language, and nonlanguage tests. In LBD patients, there was a greater association between performance on verbal and nonverbal implicatures and between performance on implicatures and basic speech acts than in RBD patients. Given the different modes in which right-and left-hemisphere (LH) damage affect the processing of conversational implicatures, it remains to be discovered how the two hemispheres interact to process natural language pragmatics in the normal brain in real time.     

The acquisition of homonymy

The growth in children's ability to perform the task of separating the sounds of words from their meanings was investigated by asking children between 3;3 and 6;3 to select homonyms from pictures. The results show a growth in ability with age, with a jump at 4;4. An investigation of the developmental changes in the strategies employed shows that the task is cognitively complex. Performance in the younger children is more hampered by a resource-limited inability to cope with many cognitive factors all at once than by lack of ability to do the linguistic aspects of the task. These cognitive factors include access to vocabulary, rehearsal of intermediate results, and implementation of a search strategy.     

Intergroup emotions and gateway groups: Introducing multiple social identities into the study of emotions in conflict

After 2 decades of extensive empirical studies on affective intergroup processes, it is now clear that emotional processes play a critical role in the dynamics of intergroup conflict. However, it seems that much of the research in this domain views intergroup relations in a dichotomous manner of pure in‐groups and out‐groups despite the developments in the realm of social identity that suggest otherwise. We here suggest that the incorporation of more complex social identity models into the study of affective social science can not only help to better understand intergroup conflict dynamics but can also offer new possible venues for conflict resolution. Specifically, we claim that the presence of groups with multiple identities, which include both the in‐group's and the out‐group's identity (e.g., biracial groups that encompass both a White and a Black social identity) can impact intergroup emotional processes between the different groups comprising those multiple identities (e.g., between Whites and Blacks). Accordingly, we review recent developments in the literatures of emotion in intergroup conflict and multiple social identity and offer a conceptual integration of the two. Thus, we attempt to enrich the theory in both fields, better explain intergroup conflict, and possibly pave the way for the development of novel conflict resolution methods.     

Promoting intergroup openness and support for equality in a new cultural context: Replicating the effects of internal criticism

Exposure to an outgroup member voicing criticism of his or her own group fosters greater openness to the outgroup’s perspective. Research suggests that this effect owes its influence to a serial process in which participants’ perception of the risk involved in voicing internal criticism leads to an increase in the perceived credibility of the speaker. The credibility makes it possible for the speaker to be viewed as open-minded, which subsequently inspires greater hope. This process culminates in an increased openness to the outgroup. These findings have been restricted to the Israeli-Palestinian conflict, but here we examine their generalizability to racial conflict in the United States. Results reveal that White Americans exposed to internal criticism expressed by a Black authority figure express greater openness to African-American perspectives on race relations and are more willing to support policies of racial equality. Replicating past research, this effect is serially mediated by risk, credibility, and hope.     

Successful emotion regulation requires both conviction and skill: beliefs about the controllability of emotions,reappraisal, and regulation success

To succeed in self-regulation, people need to believe that it is possible to change behaviour and they also need to use effective means to enable such a change. We propose that this also applies to emotion regulation. In two studies, we found that people were most successful in emotion regulation, the more they believed emotions can be controlled and the more they used an effective emotion regulation strategy – namely, cognitive reappraisal. Cognitive reappraisal moderated the link between beliefs about the controllability of emotion and success in emotion regulation, when reappraisal was measured as a trait (Study 1) or manipulated (Study 2). Such moderation was found when examining the regulation of disgust elicited by emotion-inducing films (Study 1), and the regulation of anger elicited by real political events (Study 2). We discuss the implications of our findings for research and practice in emotion regulation.     

Beyond Intentionality: On the Non-dual Contemplative Practices of the Tibetan Buddhist Tradition ‘The Great Perfection’

The Buddhist vision of liberation is intimately related with an experiential state that transcends intentionality, temporality and causality, owing to its non-directed, unchanging and unconditioned nature. As such, this vision reveals a novel mode of non-dual awareness, which is not divided into perceiving subject and perceived objects. In order to directly recognise this mode, several Buddhist traditions utilised diverse contemplative instructions that were meant to dissolve the intending tendencies of consciousness. This paper discusses one of these traditions – ‘The Great Perfection’ (Tib. rDzogs pa chen po) – which affirms an inherent experiential state that is open, luminous and all-encompassing. For the sake of realising such a state, this tradition advocates a contemplative approach which emphasises relaxation, spaciousness and non-intending. Through its view and practices, ‘The Great Perfection’ introduces a vision of lived experience that goes beyond the structures of intentional consciousness and entails a reassessment of our basic assumptions about human awareness.     

Are spatial and dimensional attention separate? Evidence from Posner,Stroop, and Eriksen tasks

Do various operational definitions of visual attention tap the same underlying process? To address this question, we probed visual selective attention using orientation of attention, flanker, and Stroop tasks. These were embedded in combined designs that enabled assessment of each effect, as well as their interaction. For the orientation task, performance was poorer at unexpected than at expected locations. The flanker effects also differed across the two locations. In contrast, the Stroop effects were comparable at expected and unexpected locations. We conclude that spatial attention (tapped by the orientation and the flanker tasks) and dimensional attention (tapped by the Stroop task) engage separate processes of visual selection, both of which are needed in normal attention processing.     

With or without you: The paradoxical role of identification in predicting joint and ingroup collective action in intergroup conflict

While we have a rich understanding of the motivations of disadvantaged group members to act collectively with their group, especially the important role played by identification, we know less about the disadvantaged's motivations to engage in joint action with the advantaged. This research examines the role of identification in predicting joint and ingroup collective action in intergroup conflicts. Since joint action inherently diffuses the perception of “us versus them”, we propose that identification predicts ingroup action, but not joint action. We also examine conflict intensity as a moderator, and examine how changing identification is linked to change in support for joint action. We test these hypotheses in a three-wave longitudinal study in the Palestinian–Israeli conflict. Results support our hypotheses, demonstrating that identification positively predicts ingroup action but not necessarily joint action, and that when conflict intensifies, changes in identification are negatively related to joint action with outgroup members.     

Towards a new framework of personalized psychological interventions to improve intergroup relations and promote peace

Recent increases in intergroup tensions and violence have global negative implications and underline the need for effective interventions to ameliorate conflictual relations. Despite the ongoing trend in social psychology toward an interventionist approach, there is still a theoretical and empirical gap in personalizing intergroup interventions to achieve optimal effectiveness. Integrating interventions aimed at prejudice reduction and promoting peace, we present a theoretical framework for personalizing these intergroup interventions. We propose a three‐layer model: personalization parameters, intergroup interventions, and mechanisms that link parameter and intervention. To illustrate the model, three sample parameters are described (ideology, dominant emotional sentiments, and Big Five personality types) and three corresponding mechanisms (level of intervention congruency; the degree to which an intervention addresses core appraisal theme; and a needs‐based mechanism). We demonstrate how the parameters and mechanisms map onto different established intergroup interventions, and suggest some empirical directions to test and later apply the theoretical framework. Finally, we discuss the potential of personalized interventions to substantially improve intergroup relations.     

A bright side of sadness: The depolarizing role of sadness in intergroup conflicts

Intractable conflicts constitute violent and threatening environments that lead to intense emotions and polarized attitudes. Sadness is one emotion frequently elicited by the price of such conflicts. This investigation characterized the effects of sadness on conflict‐related information processing and attitudes in the Israeli–Palestinian conflict. Findings from four experimental studies suggest that both incidental and integral sadness can induce a depolarization of political attitudes. In Study 1 (N = 163), sadness reduced the effect of political ideology on conflict‐related decisions. Sadness reduced the effect of political ideology on in‐group bias in resource allocation in Studies 2 (N = 213) and 4 (N = 274), willingness to negotiate in Studies 1 and 3 (N = 174), and openness to information supporting the out‐group's perspective (Study 4). Overall, in addition to its more negative implications, these results suggest that sadness (compared to both the non‐emotional and anger conditions) may have a bright side, since it may induce depolarization of political attitudes in intractable conflicts.
