Single-trial EEG-fMRI reveals the dynamics of cognitive function

Two major non-invasive techniques in cognitive neuroscience, electroencephalography (EEG) and functional magnetic resonance imaging (fMRI), have complementary advantages with regard to their spatial and temporal resolution. Recent hardware and software developments have made it feasible to acquire EEG and fMRI data simultaneously. We emphasize the potential of simultaneous EEG and fMRI recordings to pursue new strategies in cognitive neuroimaging. Specifically, we propose that, by exploiting the combined spatiotemporal resolution of the methods, the integration of EEG and fMRI recordings on a single-trial level enables the rich temporal dynamics of information processing to be characterized within spatially well-defined neural networks.     

Spontaneous emotion regulation during evaluated speaking tasks: associations with negative affect, anxiety expression, memory, and physiological responding

In these studies, the correlates of spontaneously using expressive suppression and cognitive reappraisal during stressful speeches were examined. Spontaneous emotion regulation means that there were no instructions of how to regulate emotions during the speech. Instead, participants indicated after the speech to what extent they used self-motivated expressive suppression or reappraisal during the task. The results show that suppression is associated with less anxiety expression, greater physiological responding, and less memory for the speech while having no impact on negative affect. In contrast, reappraisal has no impact on physiology and memory while leading to less expression and affect. Taken together, spontaneous emotion regulation in active coping tasks has similar consequences as experimentally induced emotion regulation in passive tasks.     

Child social skills training in developmental crime prevention: effects on antisocial behavior and social competence

Social skills training for children is becoming increasingly popular as a measure for developmental crime prevention. Although previous reviews of such programs have shown positive effects, they have also revealed problems of research design, outcome measures, and long-term follow up. Accordingly, this article reports on a recent meta-analysis of randomized evaluations of the effect of social skills training in preventing antisocial behavior and promoting social competence. Of 841 retrievable references, 84 research reports with a total of 136 treatment-control comparisons fulfilled the eligibility criteria. Results showed a small but significant overall positive effect of d = .39 at post-intervention and d = .28 at follow-up (3 months and later). Effect sizes were somewhat greater for outcome measures of social competence than for measures of antisocial behavior, particularly when delinquency was assessed. Cognitive-behavioral programs revealed the best results in terms of generalization over time and on outcome criteria. In addition, prevention measures indicated for children and adolescents who already manifested some behavioral problems had higher effect sizes than universal approaches. Because most studies dealt with small sample sizes, non-official outcome data, and measurements after less than one year, the results should be interpreted with caution. Further high-quality studies with long-term empirical outcome criteria are needed, particularly outside the United States.     

Coping with terrorism: the impact of increased salience of terrorism on mood and self-efficacy of intrinsically religious and nonreligious people

It was hypothesized that intrinsic religiousness helps to cope with increased salience of terrorism. Intrinsically religious and non-religious participants were told that it is highly probable or highly improbable, respectively, that terrorist attacks will occur in Germany. High probability of terrorism only negatively affected the mood of non-religious participants but not of intrinsically religious participants (Study 1). Using as a realistic context of investigation the terrorist suicide bombings in Istanbul, the authors replicated this finding and shed some light on the underlying psychological processes (Study 2): On the day of the terrorist attacks (high salience of terrorism), non-religious participants experienced less positive emotions and less self-efficacy than did intrinsically religious participants. Two months later (low salience of terrorism), no differences were found between non-religious and intrinsically religious participants with regard to mood and self-efficacy. Mediational analyses suggested that the mood effects were associated with differences in the reported sense of self-efficacy.     

Selective exposure: The impact of framing information search instructions as gains and losses

Previous research has found that people prefer information that supports rather than conflicts with their decisions (selective exposure). In the present paper, we investigated whether selective exposure was influenced by the method of information collection. Based on Prospect Theory we hypothesized that the method of selection (MOS), where simply selected pieces of information are considered, would lead to a higher selective exposure compared to the method of elimination (MOE), where pieces of information are rejected and the remaining pieces of information are considered. In fact, we found that participants collected information more selectively when they were instructed to use the MOS compared to the MOE. Copyright © 2009 John Wiley & Sons, Ltd.     

Book received

In his recent article, titled ‘Royaumont Revisited’, Overgaard challenges Dummett's view that one needs to go as far back as the late nineteenth century in order to discover examples of genuine dialogue between ‘analytic’ and ‘continental’ philosophy. Instead, Overgaard argues that in the 1958 Royaumont colloquium, generally judged as a failed attempt at communication between the two camps, one can find some elements which may be utilized towards re-establishing a dialogue between these two sides. Yet, emphasising this image of Royaumont as a kind of battleground between ‘analytic’ and ‘continental’ philosophy obscures the plurality of philosophical approaches involved. Royaumont was the meeting point of more than two philosophical traditions, as can be shown by the divergent interests of its participants. Thus, though the potential for rapprochement between Oxford ‘linguistic philosophy’ and a certain strand of phenomenological thought may indeed be found among the discussions that took place during the colloquium, one should keep in mind that such rapprochement took place in the context of a meeting between, among others: continental ‘analytics’, Anglophone non-‘analytics’, French historians of philosophy, ‘analytic’ opponents of Oxford philosophy, Franciscan phenomenologists, and Oxonians who called their work ‘phenomenology’.     

Working memory capacity predicts the beneficial effect of selective memory retrieval

Selective retrieval of some studied items can both impair and improve recall of the other items. This study examined the role of working memory capacity (WMC) for the two effects of memory retrieval. Participants studied an item list consisting of predefined target and nontarget items. After study of the list, half of the participants performed an imagination task supposed to induce a change in mental context, whereas the other half performed a counting task which does not induce such context change. Following presentation of a second list, memory for the original list's target items was tested, either with or without preceding retrieval of the list's nontarget items. Consistent with previous work, preceding nontarget retrieval impaired target recall in the absence of the context change, but improved target recall in its presence. In particular, there was a positive relationship between WMC and the beneficial, but not the detrimental effect of memory retrieval. On the basis of the view that the beneficial effect of memory retrieval reflects context-reactivation processes, the results indicate that individuals with higher WMC are better able to capitalise on retrieval-induced context reactivation than individuals with lower WMC.     

Beyond Art and Beauty: In Search of the Object of Philosophical Aesthetics

This article deals with the ambigous situation of philosophical aesthetics, which now seems to have lost its proper object. Moreover, Arthur C. Danto has popularized talk of an end of art, in which he ties that end to the end of any aesthetic master narrative. Comparing modern and medieval approaches to art, this paper tries to reformulate the question of philosophical aesthetics, which has to be understood in a hermeneutical way. Taken in a heuristic manner 'art' and 'beauty' remain the principal aesthetic categories able to keep the understanding of what belongs to aesthetics open to different historical approaches.     

How to achieve synergy in group decision making: Lessons to be learned from the hidden profile paradigm

Based on over 25 years of research on hidden profiles and information sharing in groups, and particularly our own work in this area, we outline a general model of how groups can achieve better decisions in a hidden profile situation than their individual members would have been capable of (i.e., synergy). At its core the model defines intensity and bias as the two key parameters that have to be optimised with regard to both the discussion of information and the processing of information in order to ensure synergy in group decision making. We review the empirical literature on information sharing and group decision making in the hidden profile paradigm (with a particular focus on our own studies) to illustrate how group decision quality can be enhanced by increasing intensity and decreasing bias in the discussion and processing of information. Finally we also outline why we think that the lessons learned from research using the hidden profile paradigm can be generalised to group decision-making research in general, and how these lessons can stimulate studies in other fields of group decision-making and group performance research.     

Deception in Experiments: Revisiting the Arguments in Its Defense

In psychology, deception is commonly used to increase experimental control. Yet, its use has provoked concerns that it raises participants' suspicions, prompts second-guessing of experimenters' true intentions, and ultimately distorts behavior and endangers the control it is meant to achieve. Over time, these concerns regarding the methodological costs of the use of deception have been subjected to empirical analysis. We review the evidence stemming from these studies.
