Cerebellum and processing of negative facial emotions: cerebellar transcranial DC stimulation specifically enhances the emotional recognition of facial anger and sadness

Some evidence suggests that the cerebellum participates in the complex network processing emotional facial expression. To evaluate the role of the cerebellum in recognising facial expressions we delivered transcranial direct current stimulation (tDCS) over the cerebellum and prefrontal cortex. A facial emotion recognition task was administered to 21 healthy subjects before and after cerebellar tDCS; we also tested subjects with a visual attention task and a visual analogue scale (VAS) for mood. Anodal and cathodal cerebellar tDCS both significantly enhanced sensory processing in response to negative facial expressions (anodal tDCS, p=.0021; cathodal tDCS, p=.018), but left positive emotion and neutral facial expressions unchanged (p>.05). tDCS over the right prefrontal cortex left facial expressions of both negative and positive emotion unchanged. These findings suggest that the cerebellum is specifically involved in processing facial expressions of negative emotion.     

An inhibition effect in the temporal constrains of attentional selection: the Backward Blink

The study aims at investigating the dynamics of visual information processing during sequential control of attentional selection. By combining two different traditional paradigms we show for the first time that during rapid selection of visual targets, encoding of a new target stimulus is facilitated by suppression of the preceding relevant stimulus category (Backward Blink; BB). Such inhibition would operate to reduce interference from previously stored information, in order to facilitate the instantiation of a new attentional episode. Results suggest that the same underlying inhibitory mechanism might contribute to two different attentional effects, specifically, the switch cost and the Attentional Blink, suggesting a general inhibitory mechanism of attentional control, with broad implications for understanding how the brain perceives any task-relevant stimulus.     

BARBOUR'S TYPOLOGIES AND THE CONTEMPORARY DEBATE ON ISLAM AND SCIENCE

Abstract Despite various criticisms, Ian Barbour's fourfold classification of the possible relationships between religion and science remains influential. I compare Barbour's taxonomy with the theories of four authors who, in the last four decades, have addressed the relationship between science and religion from a Muslim perspective. The aim of my analysis is twofold. First, I offer a comparative perspective to the debate on science and Islam. Second, following Barbour's suggestion, I test the general applicability of his categories by comparing them with a discourse on science and religion that is not focused on Christianity. In the first section, I reconstruct Barbour's typologies, recalling some major objections to them, and arguing why despite the latter, Barbour's model is employed for the present analysis. I also reconstruct Barbour's parallel model for the relationships between different religions. In the second section, I reconstruct the discourse on science and religion developed by the Palestinian‐American scholar Ismail Raji al‐Faruqi. The third section is devoted to the ideas of the Persian‐American scholar Seyyed Hossein Nasr. In the fourth section, I examine the views of the Iranian author Mehdi Golshani. The fifth section reconstructs the theories of the Algerian author Nidhal Guessoum. In the final section, I argue that a generalized use of the “integration” concept to refer to the entire debate on Islam and science is unhelpful. While these positions do not appear to instantiate Barbourian integration of science and religion, they do move toward what Barbour (skeptically) describes as integration between religions.     

Comparison between Gudjonsson Suggestibility Scale 2 (GSS2) and Bonn Test of Statement Suggestibility (BTSS) in measuring children’s interrogative suggestibility

Susceptibility of children to leading questions and interrogative pressure is an important forensic issue. The most used techniques for assessing interrogative suggestibility are the Gudjonsson Suggestibility Scales (GSS) and the Bonn Test of Statement Suggestibility (BTSS). Apart from minor differences, the two tests, investigate the same dimensions: Yield, Shift, Immediate Recall, and Total Suggestibility. In this study, to investigate correlation measures for the corresponding variables in the two tests, we individually examined 84 children from the fourth and fifth grades (44 boys and 40 girls). All the participants completed the GSS2 the BTSS-1, the Vocabulary and the Similarity subtests of the WISC-R, and Raven’s Colored Progressive Matrices. No significant gender differences were observed for any of the variables studied. Comparison between the corresponding variables for the two tests showed a positive correlation. Yield and Total Suggestibility scores correlated negatively with the three cognitive variables. We conclude that although the two suggestibility scales measure analogous variables, the BTSS seems more suitable than the GSS2 for assessing a child’s suggestibility during police and forensic interviews.     

Positive experiences of doctoral-level supervisors-in-training conducting group-format supervision: a qualitative investigation

Experiential learning opportunities are powerful in shaping positive supervisor behaviours. We were interested in examining the positive experiences of supervisors-in-training during their first practice experience as supervisors. Our study was guided by two research questions: (a) what are the experiences that supervisors-in-training viewed as positive during the course of providing clinical supervision to master's-level counselling trainees? and (b) how did these positive experiences contribute to their professional development? We employed a variation of the consensual qualitative research method developed by Hill, Thompson, and Nutt-Williams (1997) and interviewed 10 supervisors-in-training regarding their positive experiences in supervising master's-level counselling trainees. The results included five major categories of positive experiences: (a) the positive value of feedback; (b) enhanced confidence in using a wider variety of supervision tasks and procedures; (c) the impact of the experience on other aspects of professional practice; (d) increased familiarity with the multiple roles of the supervisor; and (e) for some, increased comfort navigating co-supervision dynamics. Each of these categories included subcategories. We discuss our findings within the context of supervision training in graduate education.     

The bias in the bias: Comparative optimism as a function of event social undesirability

We present a new event-level predictor of comparative optimism: comparative optimism is larger for more socially undesirable events. A meta-analysis shows that event social undesirability predicts comparative optimism effect sizes reported in the literature, over and above the effects of other known predictors. Four experiments corroborate this finding and demonstrate the key role played by respondents’ impression management motives. The effect of social undesirability decreases with stronger than usual anonymity assurances, increases with greater impression management tendencies, and reverses when people want to make a negative impression. Because social undesirability is correlated to other known predictors of comparative optimism (e.g., controllability, severity), it is important to take its effects into account when assessing the effect of other event characteristics. The current research adds to, and bridges, the literatures on event-level predictors and impression management in comparative optimism.     

Religion at the European Parliament: the Italian case

Italy is a predominantly Catholic country that developed historically on the basis of a strong, dominant religion and weak state institutions. Yet, openly clerical parties, direct advocates of the interests of the Catholic Church, have nowadays virtually disappeared and the relevance of the religious cleavage is decreasing, in favour of a more indirect support for these interests, mainly among moderate and conservative forces. Although the overall level of secularisation in Italy has increased, the degree of religiosity of Italian society remains one of the highest of the 27 member-states of the European Union (EU) and polarisation over religious issues in domestic politics remains high, particularly regarding moral values and family matters. In our study we explore the role of religion within the Italian political sphere with regard to the functioning of political representation, by taking into account the sub-national, national and European levels of government. We focus on the attitudes and behaviours of Italian political elites at the EU level. We hypothesise a strong influence of religion on the articulation between national and European politics. Our findings consistently show that the degree of religiosity of the Italian delegation to the European Parliament (EP) is high. However, the impact of such a high degree of religiosity among the members of the EP (MEPs) on their political activities appears less direct than one might predict, while the degree of political secularism is higher among Italian MEPs than among their national or regional counterparts. When we discuss a case study, namely the accession of Turkey to the EU, our data show that the religious attitudes of Italian MEPs play a crucial role in their stance on Turkish accession. The picture that emerges is thus nuanced. Religion significantly impacts on Italian MEPs’ ideological, political and moral attitudes, but plays a smaller role in their activities; while their left-right collocation emerges as the most relevant predictor, despite a number of exceptions.     

Different contexts change the impression of animacy

The aim of this research was to explore the effect of different spatiotemporal contexts on the perceptual saliency of animacy, and the extent of the relationship between animacy and other related properties such as emotions and intentionality. Paired-comparisons and ratings were used to compare the impressions of animacy elicited by a small square moving on the screen, either alone or in the context of a second square. The context element was either static or moving showing an animate-like or a physical-like trajectory, and the target object moved either toward it or away from it. The movement of the target could also include animacy cues (caterpillar-like expanding/contracting phases). To determine the effect of different contexts on the emergence of emotions and intentions, we also recorded and analysed the phenomenological reports of participants. The results show that the context significantly influences the perception of animacy, which is stronger in dynamic contexts than in static ones, and also when the target is moving away from the context element than when it is approaching it. The free reports reveal different proportions in emotional or intentional attributions in the different conditions: in particular, the "moving away" condition is related to negative emotions, while the "approaching" condition evokes positive emotions. Overall, the results suggest that animacy is a graded concept that can be articulated in more general characteristics, like simple aliveness, and more specific ones, like intentions or emotions, and that the spatiotemporal contingencies of the context play a crucial role in making them evident.     

Psychometric Aspects of the Depressive Experiences Questionnaire: Implications for Clinical Assessment and Research

The Depressive Experiences Questionnaire (DEQ) is a self-report measure that assesses self-criticism and dependency, 2 personality traits that confer vulnerability to depression (Blatt, 2004 Blatt, S. J. (2004). Experiences of depression: Theoretical, clinical, and research perspectives. Washington, DC: American Psychological Association.[Crossref] , [Google Scholar]). Over several decades, different, shortened versions of the DEQ have been constructed to offer an alternative to the complex scoring procedure of the original DEQ. This study explores the factor structure as well as the construct and convergent validity of the DEQ by comparing a clinical and nonclinical sample. We also compared the original DEQ with 5 shortened versions. There were 621 participants (358 university students and 263 outpatients). Fit indexes for models of the original DEQ did not meet minimum fit criteria. Moreover, the only versions with satisfactory fit were the Theoretical Depressive Experiences Questionnaire–21 (TDEQ–21) and the Theoretical Depressive Experiences Questionnaire–12 (TDEQ–12), which also showed acceptable construct and convergent validity. Finally, the diagnostic and clinical applicability of the DEQ is discussed.
