No full textPsoriasis is a chronic debilitating disease which is frequently associated with strong psychological distress and psychological conditions (e.g., depression, anxiety). Although some studies have indicated a relationship between this condition and difficulties in emotion regulation (as they are self-reported by the patients), behavioral and physiological evidence about this link are scarce. Here, we measured emotion regulation abilities of patients with psoriasis (N=16) and a control group (N=17) by examining the impact of distracting emotional (positive, negative or neutral) images during the performance on a working memory task (“Emotional n-back”) which could present high (1 back) or low (2 back) cognitive workload. Moreover, we used Functional Infrared Thermal Imaging to record participants’ facial temperature in order to obtain a measure of the activation of the autonomic system during the task. In particular, temperature over the peri-orbital areas and the tip of the nose are believed to reflect the activation of the sympathetic and parasympathetic system, respectively. Patients scored significantly higher than controls on the “Lack of emotional clarity” subscale of the Difficulties in Emotion Regulation Scale (DERS). Compared to the control group, patients showed to improve their performance when the cognitive workload was higher (and then it was easier not to pay attention to the distracting stimuli) but only when the distracting image was neutral. Consistently with this behavioral pattern, patients showed a lower temperature of periorbital areas and a higher temperature of the tip of the nose (especially in the neutral blocks) during the high vs low cognitive load condition. These results suggest that patients with difficulties in understanding their emotions might benefit more than controls from the distracting power of cognitive load. However, this advantage seems to extinguish when the distractors are emotionally charged
Weaker inhibition after happy faces: evidence from an attentional blink task with emotional and neutral faces
No full textIn two experiments using a Rapid Serial Visual Presentation (RSVP) we investigated how emotional and neutral faces (T1) modulate temporal attention for a following neutral face (T2). Typically, performance for T2 is spared when T2 immediately follows T1 (lag 1 sparing) but it is impaired when T2 is presented within 500 ms from T1 (Attentional Blink). Experiment 1 shows a shorter attentional blink following happy faces, relative to neutral and sad faces, which did not differ. Experiment 2 shows a lag 1 sparing only after happy T1s, but not after angry or neutral T1s, and a greater attentional blink following happy and angry T1-faces, compared to neutral T1-faces. Results indicate that happy faces exert different effects on temporal attention than negative (angry or sad) faces. Findings are discussed in terms of an interplay of resource depletion, due to emotional salience, and emotion-specific inhibitory mechanisms

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Contributions of the right prefrontal and parietal cortices to the attentional blink: a tdcs study
Full text linkThe AB refers to the performance impairment that occurs when visual selective attention is overloaded through the very rapid succession of two targets (T1 and T2) among distractors by using the rapid serial visual presentation task (RSVP). Under these conditions, performance is typically impaired when T2 is presented within 200–500 ms from T1 (AB). Based on neuroimaging studies suggesting a role of top-down attention and working memory brain hubs in the AB, here we potentiated via anodal or sham tDCS the activity of the right DLPFC (F4) and of the right PPC (P4) during an AB task. The findings showed that anodal tDCS over the F4 and over P4 had similar effects on the AB. Importantly, potentiating the activity of the right frontoparietal network via anodal tDCS only benefitted poor performers, reducing the AB, whereas in good performers it accentuated the AB. The contribution of the present findings is twofold: It shows both top-down and bottom-up contributions of the right frontoparietal network in the AB, and it indicates that there is an optimal level of excitability of this network, resulting from the individual level of activation and the intensity of current stimulation
Asymmetric contributions of the fronto-parietal network to emotional conflict in the word-face interference task
Full text linkThe fronto-parietal network is involved in top-down and bottom-up processes necessary to achieve cognitive control. We investigated the role of asymmetric enhancement of the left dorsolateral prefrontal cortex (lDLPFC) and right posterior parietal cortex (rPPC) in cognitive control under conditions of emotional conflict arising from emotional distractors. The effects of anodal tDCS over the lDLPFC/cathodal over the rPPC and the effects of anodal tDCS over the rPPC/cathodal over the lDLPFC were compared to sham tDCS in a double-blind design. The findings showed that anodal stimulation over the lDLPFC reduced interference from emotional distractors, but only when participants had already gained experience with the task. In contrast, having already performed the task only eliminated facilitation effects for positive stimuli. Importantly, anodal stimulation of the rPPC did not affect distractors’ interference. Therefore, the present findings indicate that the lDLPFC plays a crucial role in implementing top-down control to resolve emotional conflict, but that experience with the task is necessary to reveal this role
