Using facial emotional stimuli in visual search experiments: The arousal factor explains contradictory results

For more than two decades, visual search experiments using pictures of emotional faces as stimuli have generated contradictory results. Evidence of a superior detection of angry faces compared to happy faces have been mixed with an equal amount of evidence in the opposite direction. In this article, we review this literature, and examine the hypothesis that the neglected stimulus factor of emotional arousal may explain these contradictory results. Through an extensive reanalysis of results from our own laboratory as well as from other researchers, we show that the arousal factor systematically influences the outcome of the reviewed visual search experiments, and may thus provide a key to the historical contradictions within this research field.     

Determination of problems in patients with post‐laryngectomy

The purpose of this study is the determination of the physical and psychosocial problems of total and partial laryngectomies. A total of 25 patients, who were operated with the diagnosis of larynx carcinoma in 2010 at Gazi University Faculty of Medicine Otolaryngology Department, were included in the study. They were evaluated with the help of the Personal Information Form (PIF) and the Determination Form of Post Laryngectomy Problem (DFPLP) for the problems they encountered after the operation. Total laryngectomy (TL) was performed on 76% of patients. It was determined that patients undergoing total laryngectomy experienced some physical and psycho‐social problems such as problems in sleep (31.6%), smell (52.6%), taste (36.8%), and difficulty in swallowing solid foods (36.8%). Furthermore in patients with TL surgery whilst 47.4% of them think that their sexual lives were affected rather negatively, this rate was determined as 33.3% in patients with partial laryngectomy surgery (PL). The psychosocial score averages of the patients who had smell and taste disorders were significantly lower (p < 0.05). The patients, who underwent a laryngectomy operation, experienced many physical, social, and psychological problems. Thus, medical personnel also need to pay attention to these concomitant problems that occur during the treatment of the primary disease and the application of necessary supplementary treatments such as voice prosthesis, pre‐op and post‐op counseling, and anti‐depressants seems significant in terms of increasing the life quality of the patients.     

Comparing two independent groups: A test based on a one‐step M‐estimator and bootstrap‐t

A new test is proposed for the problem of comparing two independent groups in terms of some measure of location. The proposed test () uses a one‐step M‐estimator and a bootstrap‐t method with the procedure proposed by Özdemir and Kurt (2006) . Eight methods were compared in terms of actual Type I error and power when the underlying distributions differ in skewness and kurtosis under heterogeneity of variances. For the 21 theoretical distributions, the Yuen test with the bootstrap‐t method was the most favourable, followed by test. For the five real data sets, the proposed test and percentile bootstrap method with the one‐step M‐estimator performed best.     

伤害回避的脑机制及其生物基础

伤害回避是指个体对厌恶刺激信号做出强烈的反应,并学会被动地回避惩罚的一种倾向,这一倾向使得个体反复思考未来的结局,并谨慎小心地对待不确定情景中的事件,进而更有可能诱发情感障碍。伤害回避涉及的神经网络包括三个子网络,即额顶叶-前扣带皮层的连接、皮层-杏仁核的连接和白质通道的结构性连接,这三个子网络分别与羞怯感-易疲劳性、预期担心以及不确定环境中的害怕情绪有关。而其生物基础则包括单一基因多态性和基因多态间的交互作用。今后的研究应该集中在深化伤害回避神经网络与生物基础间的联合机制、研究三种及以上基因多态间的交互作用、考察其他因素对基因效应的调节作用、注重伤害回避四种亚型相关神经网络之间的连接、探讨5-HT4等其他几种5-羟色胺受体多态性与伤害回避的关系以及分析伤害回避内部机制在抗抑郁治疗中的作用等方面。     

Top-down attentional modulation of spatial frequency processing in scene perception

Recent evidence suggests that spatial frequency (SF) processing of simple and complex visual patterns is flexible. The use of spatial scale in scene perception seems to be influenced by people's expectations. However as yet there is no direct evidence for top-down attentional effects on flexible scale use in scene perception. In two experiments we provide such evidence. We presented participants with low- and high-pass SF filtered scenes and cued their attention to the relevant scale. In Experiment 1 we subsequently presented them with hybrid scenes (both low- and high-pass scenes present). We observed that participants reported detecting the cued component of hybrids. To explore if this might be due to decision biases, in Experiment 2, we replaced hybrids with images containing meaningful scenes at uncued SFs and noise at the cued SFs (invalid cueing). We found that participants performed poorly on invalid cueing trials. These findings are consistent with top-down attentional modulation of early spatial frequency processing in scene perception.     

Koran reading and negotiation with jinn: strategies to deal with mental ill health among Swedish Somalis

In this paper, we discuss traditional Somali concepts of mental ill health. Qualitative interviews were conducted with some 20 Swedish Somali interviewees about factors causing mental ill health, traditional classification, strategies to deal with mental ill health, and attitudes to the mental health care services in Sweden. Social mobilisation and religious healing are cornerstones of traditional Somali measures to deal with mental suffering. Traditional Somali views of mental ill health stand in stark contrast to classification of mental ill health in the western biomedical model. These views deserve attention since they may have an impact on health-seeking behaviour among Somali immigrants in western countries. Yet a too strong focus on cultural aspects may over-shadow the fact that much mental suffering among Somali migrants must be understood within social, economic, and political contexts.     

Gender and power in school: On girls' open resistance

Drawing upon a Swedish empirical study of gender and power relations in a 9th-grade classroom, this paper focusses especially on girls' attempts to gain influence in school. Typically, such behaviours are reported to be more frequently exhibited by boys, as is almost all kinds of public classroom participation. In the class reported on here, however, girls are those actively contesting power relations and pursuing their principles. This is done through a process much resembling the idea of a representative democratic model. The features and implications of this process are elaborated in relation to two conflicts taking place in the class.     

Respectable,Disreputable, or Rightful? Young Nicaraguan Women’s Discourses on Femininity,Intimate Partner Violence,and Sexual Abuse: A Grounded Theory Situational Analysis

This situational analysis study aims to position the discourses that young Nicaraguan women use in their understanding of femininities, male intimate partner violence (IPV), and men’s sexual violence toward women (SA). Eight focus group discussions with a total of 59 women were conducted. Positional maps were used to display the data. The findings show a dominant discourse that portrays femininity as enacting attributes habitually bestowed to men such as independence and agency, while still upholding key patriarchal conceptions (respectability) limiting women’s agency. Tolerance of IPV and SA by nonpartners varies depending on women’s perceived respectability and agency. Most important, we identified a pro-women’s rights resistance discourse that constructs femininity and advocates nonviolence from a human rights perspective.
