Linguistic intergroup bias in political communication

The Linguistic Intergroup Bias (LIB) illustrates the disposition to communicate positive in-group and negative out-group behaviors more abstractly than negative in-group and positive out-group behaviors. The present research examined the function of language in reinforcing this bias in political communication. To illustrate the LIB, the Linguistic Category Model (LCM) was used, including a nouns category. Because social stereotypes are usually conveyed by nominal terms, the aim was to observe the relationship between stereotypes and language in political communication. Moreover, we were interested in analyzing the psychological processes that drive the LIB. Therefore, we verified whether the LIB is more related to language abstractness than to agent-patient causality. Several political debates and interviews, which took place before the latest Italian provincial elections, were analyzed. Results suggested that the language politicians use in communicating about political groups are conceptualized as stereotypes rather than as trait-based categories. Moreover, it seems that the LIB could not be explained only at a lexical level. Social implications of the present findings in interpersonal relations and causal attribution were discussed.     

rTMS for PTSD: induced merciful oblivion or elimination of abnormal hypermnesia?

Neuroimaging studies and experimental data suggest that symptoms of posttraumatic stress disorder (PTSD) are associated with dysfunctions of neural circuits linking prefrontal cortex and the limbic system that have a role in autobiographic episodic memory. High-frequency repetitive transcranial magnetic stimulation (rTMS) of the right dorsolateral prefrontal cortex (DLPFC) has been suggested to be beneficial to patients with PTSD, transiently alleviating re-experiencing as well as avoidance reactions and associated anxiety symptoms. In healthy humans, converging evidence suggests that rTMS of the right DLPFC interferes with episodic memory retrieval. Hence, we hypothesize that daily applications of rTMS in PTSD patients may reduce access to the set of autobiographical stored events, that, if re-experienced, may cause the overt PTSD symptoms.     

Bion’s O and His Pseudo-Mystical Path

The concept of Bion of O is both essential and elusive like few others. By its ambiguous nature it gives rise to the most disconcerting interpretations and many misunderstandings. Among these is the idea of inaugurating a “mystical” psychoanalysis. To refute this thesis, the author proposes a path of reading that is certainly personal and at times even impervious, but that aims to insert this notion within a theoretical framework that is as clear, logical and coherent as possible. The meaning of the concept of O is only delineated in the relationship with other key concepts (mainly: transformation, invariant and at-one-ment). It therefore escapes us if we do not take into account the dialectical tension that arises from this fruitful trade and if we do not pay attention to the always different discursive contexts in which it is found. But above all it is important to realize that the concept of O is peculiar also in comparison to other more clearly specified and circumscribed concepts of Bion. In fact, it itself consists of a constellation of concepts, as many names or partial definitions.     

Common future and personal responsibilities: A comparison between Italian and Burundian students

The political, social, and cultural history of a nation modulates the representations of rights and duties. The aim of this research is to compare students from two countries (Italy and Burundi) in terms of how they define their rights and duties. In the two countries, there are differences both in the legal protection of fundamental rights and in regard to material conditions, which in turn ensure the effectiveness of rights. Focus groups structured around nine questions were conducted in Burundi and in Italy. The discussions with Italian and Burundian students showed some clear differences. Although both groups speak of rights as something to be safeguarded and something that everyone is born with, Italian students do not recognize the complementarity of rights and duties and consider the latter simply as a limit and an obstacle to individual enhancement. On the contrary, Burundian adolescents seem more aware of their personal responsibilities and their role in protecting human rights.     

Priming Effects on Commitment to Help and on Real Helping Behavior

Years of research on bystander apathy have demonstrated that the physical presence of others can reduce the tendency to help individuals needing assistance. Recent research on the implicit bystander effect has suggested that simply imagining the presence of others can lead to less helping behavior on a subsequent unrelated task. The present study was designed to contribute to previous findings on the implicit bystander effect by demonstrating these effects on commitment to help and on real helping behavior, rather than simply on intentions to help. Studies 1a and 1b demonstrate that merely priming participants with the construct of being in a group at Time 1 created significantly less commitment to future helping on a subsequent task at Time 2. Study 2 aimed to extend this effect to behavioral measures and verified that participants exposed to a group prime helped less than those who were exposed to a single-person prime. The implications of these findings for the literature on the bystander effect are discussed.     

FOCUS: ComplexityandPsychology Guest Editors: Giuseppe Mininni and Mauro Maldonato

Recently the complexity of discursive practices has been widely acknowledged by the humanities and social sciences. In fact, to know anything is to know in terms of one or more discourse. The “discursive turn” in psychology may be considered as a new paradigm oriented to a correct study of (wo)man only if it is able to grasp the semiotical ground of psychic experience both as an “effort after meaning” and as a “struggle over meaning.” In this sense the notion of “diatext” has been proposed as a contribution in working out a psychosemiotical approach to understand how the discursive practices assign subject-positions to the agents of each interlocution scenario.     

Beyond the emotional event: Six studies on the social sharing of emotion

Abstract

We argue that emotion cannot only be conceived of as a short-lived and intrapersonal phenomenon. Rather, based on five theoretical arguments, we propose that the social sharing of an emotional experience forms an integral part of the emotional processes. A series of six studies investigated different aspects of this hypothesis. Study 1 showed that an overwhelming majority of people reported sharing their emotional experiences and that the memories of these experiences tended to come back spontaneously to their consciousness. No difference was found among emotions. Using a different procedure, Studies 2 and 3 replicated these findings in two different populations. In addition, these studies provided indications that women share their experiences with a wider array of individuals than do men. The first three studies did not find any differences among emotions, but they did not include shame. It could be argued that people are less inclined to socially share shame experiences which are typically elicited by breaking social rules. Study 4 specifically investigated this hypothesis. No differences among shame and other emotions were found except for the delay of the first sharing of the experience. Study 5 constituted a first investigation of whether the social sharing of emotion is also a significant process in now Western cultures. A comparison between Dutch and Surinamese people failed to reveal any significant difference. Based on the findings of the first five studies, a correlational model was designed in Study 6. It tested the interrelationships among disruptiveness of the emotion, social sharing, mental rumination, and recovery from the emotion disruption. A coherent pattern of findings emerged, showing that social sharing can be conceived as a bi-dimensional concept defined by features of amount and delay of sharing. In addition, both social sharing and mental rumination varied according to the disruptiveness of the emotion. Surprisingly, however, recovery could not be related to social sharing, mental rumination, or to the time elapsed since the episode.     

Objective assessment of the functional role of spike train correlations using information measures

The functional role of correlations between neuronal spike trains remains strongly debated. This debate partly stems from the lack of a standardized analysis technique capable of accurately quantifying the role of correlations in stimulus encoding. We believe that information theoretic measures may represent an objective method for analysing the functional role of neuronal correlations. Here we show that information analysis of pairs of spike trains allows the information content present in the firing rate to be disambiguated from any extra information that may be present in the temporal relationships of the two spike trains. We validate and illustrate the method by applying it to simulated data with variable degrees of known synchrony, and by applying it to recordings from pairs of sites in the primary visual cortex of anaesthetized cats. We discuss the importance of information theoretic analysis in elucidating the neuronal mechanisms underlying object identification.

Brain Oxidative Damage Following Acute Immobilization and Mild Emotional Stress

We studied the role of free radicals on brain oxidative damage in rats after acute immobilization stress (restraint) and mild emotional stress (handling). To investigate brain oxidative damage, CuZn and Mn dependent superoxide dismutase (CuZn SOD, Mn SOD) activities, lipid peroxidation (TBARs), Na ⁺ K ⁺ ATPase activity, protein carbonyl (PrC), and reduced and oxidized glutathione (GSH, GSSG) levels were measured in the cerebral cortex (CTX), hippocampus (HIP), and striatum (ST) of the animals after the two different stress stimuli. Because stress produces abnormalities in the hypothalamic-pituitary-adrenal axis, the intensity of the two stress conditions were measured by plasmatic corticosteroid (COR) levels: particularly, COR levels doubled in handled rats and increased 15-fold in restrained animals. The SOD activities increased in CTX and decreased in HIP of the handled rats, while in ST a significant decrease in handled animals but an increase in restrained animals occurred. TBARs, GSH, and GSSG levels remained unchanged, while an index of glutathione redox decreased significantly in ST of handled animals and in CTX of restrained ones. Na ⁺ K ⁺ ATPase activity increased significantly in the HIP and ST of both groups of stressed rats. The stress induced a remarkable increase in PrC levels in all studied cerebral areas. These findings provide evidence to support the idea that stress produces oxidants but that the oxidative damage in stress differs in cerebral areas and could contribute to the degenerative mechanism of aging.
