Task relevance modulates processing of distracting emotional stimuli

Numerous studies have claimed that emotional stimuli are able to capture attention automatically when presented outside the main focus of attention. In the current study this claim was tested by using task-relevant and task-irrelevant emotional stimuli. Specifically, in two experiments the effect of emotional stimuli presented in the periphery of attention was tested by using a flanker task. Results showed that emotional stimuli did not capture attention in an unconditional manner. Emotional distracting stimuli created interference only when they were relevant to the task. The findings suggest that "task relevance" is determined by (a) task requirements, and/or (b) target characteristics. The current results have implications for the concept of cognitive load and automaticity of processing emotional stimuli.     

Task-relevance modulates the effects of peripheral distractors

The current study investigated whether task-relevant information affects performance differently from how information that is not relevant for the task does when presented peripherally and centrally. In three experiments a target appeared inside the focus of attention, whereas a to-be-ignored distractor appeared either in the periphery (Experiments 1 and 2) or at the centre (Experiment 3) of attention. In each trial the distractor carried both task-relevant and irrelevant information. The results confirmed the “task relevance” hypothesis: Task-irrelevant information affected performance only when it appeared at the centre of attention, whereas task-relevant information affected performance when it appeared inside as well as outside the main focus of attention. The current results do not support suggestions that spatial stimuli (e.g., arrows) draw attention automatically regardless of task relevance.     

“It’s Scary but It’s Also Exciting”: Evidence of Meta-Affective Learning in Science

We study the case of Marya, a freshman engineering major who showed and spoke of a drastic shift in her feelings and approach to learning physics during an introductory course. For the first several weeks, she was anxiously manipulating equations without considering physical meaning, and she was terribly worried about being correct. By the end of the semester, however, she was sense-making and taking pleasure in it, showing and expressing an enjoyment of challenges and uncertainty. In this paper, we illustrate Marya’s transformation using data from her interview and coursework, and we propose it as an example of meta-affective learning. We argue that meta-affective learning was an important part of Marya’s physics learning and that it was deeply entangled with her developing epistemology.     

Mechanisms and the current state of transcranial magnetic stimulation

Transcranial magnetic stimulation (TMS) is unique among the current brain stimulation techniques because it is relatively non-invasive. TMS markedly differs from vagus nerve stimulation, deep brain stimulation and magnetic seizure therapy, all of which require either an implanted prosthesis or general anesthesia, or both. Since its rebirth in its modern form in 1985, TMS has already shown potential usefulness in at least three important domains-as a basic neuroscience research instrument, as a potential clinical diagnostic tool, and as a therapy for several different neuropsychiatric conditions. The TMS scientific literature has now expanded beyond what a single summary article can adequately cover. This review highlights several new developments in combining TMS with functional brain imaging, using TMS as a psychiatric therapy, potentially using TMS to enhance performance, and finally recent advances in the core technology of TMS. TMS' ability to non-invasively and focally stimulate the brain of an awake human is proving to be a most important development for neuroscience in general, and neuropsychiatry in particular.     

Women’s Experiences of Micro-Enterprise: Contexts and Meanings

The article confronts global claims of micro-enterprise to promote poverty reduction and gender equality. The article examines 60 in-depth interviews with low-income Palestinian and Israeli Jewish women (aged 25–45 years) who engaged in micro-enterprises. The research particularly focused on women’s motivations, personal qualities required for success, systemic barriers and opportunities, and women’s constructions of micro-enterprise as a means to overcome poverty and achieve gender equality. The article indicates that in the frame of gender and economic exclusionary context, without comprehensive institutional support, micro-enterprise and self employment may not promise more than a partial solution to poverty and gender discrimination. The article questions the tendency to globalize policies without taking into account the local contexts in which these policies are implemented.     

Personality and Reaction Time after Sleep Deprivation

The relationship between reaction time and both state and trait personality variables was investigated in 37 participants after 30 h of sleep deprivation. Regression analyses suggested that endorsement of greater Novelty Seeking, anger/hostility, and depression/dejection, and less confusion, was associated with greater reaction time declines on one Multi-Attribute Task Battery index after sleep deprivation. Further, greater Novelty Seeking and depression/dejection, and less vigor/activity, was associated with greater reaction time declines after sleep deprivation on another Multi-Attribute Task Battery index. Additional correlational analyses indicated that better reaction times were associated with greater Novelty Seeking and lower anger/hostility prior to sleep deprivation, and less confusion/bewilderment following sleep deprivation. Findings suggest that both state and trait personality variables are associated with reaction time performance following sleep deprivation.     

At-Risk Marriages after Compulsory Premarital Testing and Counseling for β-Thalassemia and Sickle Cell Disease in Saudi Arabia, 2005–2006

Results from a screening program for sickle cell disease and β-thalassemia suggest about 90% of couples in Saudi Arabia at risk of having affected children still decide to marry. This study determined the rate of at-risk marriages and identified several factors that may prevent at risk couples from marrying. The marriage status of 934 at-risk couples was determined from original screening program records in the Ministry of Health. Of 934 couples, 824 married (88.2%) and 110 (11.8%) did not. A case–controlled study was conducted on 104 couples who did not marry (cases) and 478 couples who did marry (controls) in order to assess relationships between various cultural and social factors and marriage decisions. In the case-controled study, 28.8% of couples (30/104) who did not marry (cases) knew their disease or carrier status before screening compared to 18% (86/478) of those who married (controls). Reasons couples gave for proceeding with marriage included: wedding plans could not be canceled, and fear of social stigma. Couples who did not marry reported being influenced by prior knowledge of their disease or carrier status and whether they or family members were affected. Approximately half of the cases and controls (n = 270, 46.4%) thought it best to undergo screening before proceeding with the engagement and wedding plans. Most couples received no advice to participate in genetic counseling services. Marriage decisions for the small number who received genetic counseling (n = 168, 27.6%) did not differ significantly from those that received no counseling. Recommendations are made for improving the effectiveness of this screening program.     

Association between substance use disorders and self- and other-directed aggression: An integrated model approach

Our study's objective is to determine whether substance use disorders’ association with aggression differs according to the type of substance and/or the form of aggression, within the same population. We used data from the National Survey on Drug Use and Health across 2008–2014, with a pooled sample of 270,227 adult respondents. We used regression models to estimate the odds ratios for those having alcohol and/or drug use disorder(s) perpetrating (a) each form of aggression compared with no aggression and (b) other-directed compared with self-directed aggression. Alcohol use disorder alone and drug use disorder(s) alone were both associated with significantly increased odds of committing self-directed, other-directed, and combined aggression. Individuals with drug use disorder(s) alone were more likely to commit other-directed than self-directed aggression (adjusted odds ratio = 1.46, 95% CI = 1.04–2.05). Individuals with alcohol use disorder alone were not likely to commit one over the other (adjusted odds ratio = 1.20, 95% CI = 0.90–1.61). In conclusion, the integrated model of aggression based on the stress–diathesis model is a relevant framework to study risk factors for aggression. Further research is needed to identify longitudinal predictors of directionality of aggression.     

Posttraumatic Symptoms, Functional Impairment, and Coping among Adolescents on Both Sides of the Israeli–Palestinian Conflict: A Cross-Cultural Approach

This study assessed the effects of the ongoing violence on the mental health of Palestinian and Israeli youths. Parallel instruments were developed and adapted, as part of a collaborative project, in order to assess, in each society: (1) differential rates of exposure to the conflict, (2) the association between exposure and the severity of posttraumatic symptoms (PTS), and (3) the inter‐relationships among PTS, functional impairment, somatic complaints, and coping strategies. Participants were 1,016 Israeli and 1,235 Palestinian adolescents. A self‐report questionnaire assessed exposure. PTS was measured using the UCLA PTSD Reaction Index, functional impairment and somatic complaints were measured with the DISC, and coping strategies were assessed with Brief Cope. In both societies, greater exposure to conflict‐related violence was associated with more PTS and more somatic complaints, with girls reporting more distress than boys. A total of 6.8 per cent of the Israeli students and 37.2 per cent of the Palestinian students met criteria for Post Traumatic Stress Disorder (PTSD). In both societies, but more pronounced in the Palestinian Authority, adolescents reported significant levels of functional impairment, mainly in the area of school functioning. Students with PTSD reported more somatic complaints as well as greater functional impairment. The results show the serious psychological impact of the ongoing violent conflict on Israeli and Palestinian students and point to the need to develop appropriate school‐based interventions to address their mental health needs. Cette étude évalue les effets de la violence continuelle sur la santé mentale des jeunes palestiniens et israéliens. Des instruments analogues ont été développés et adaptés, dans le cadre d’un projet de collaboration, afin d’évaluer dans chaque société: (1) les différences de taux d’exposition au conflit, (2) l’association entre l’exposition et la sévérité des symptômes post‐traumatiques (PTS) et (3) les interrelations entre les PTS, les troubles fonctionnels, les plaintes somatiques et les stratégies de faire‐face. 1016 adolescents israéliens et 1235 adolescents palestiniens ont participéà cette étude. Un questionnaire auto‐administré mesure l’exposition au conflit. Les PTS sont mesurés par l’utilisation de l’UCLA PTSD Reaction Index, les troubles fonctionnels et les plaintes somatiques sont approchés par le DISC, et les stratégies de faire‐face par le Brief Cope. Dans les deux sociétés, une plus grande exposition au conflit et à ses violences est associée à des PTS plus importants et à plus de plaintes somatiques, les filles manifestant plus de détresse que les garçons. Un total de 6.8% des étudiants israéliens et 37.2% des étudiants palestiniens répondent à des critères du Post Traumatic Stress Disorder (PTSD). Dans les deux sociétés, mais de façon plus prononcée dans l’Autorité palestinienne, les adolescents rapportent des niveaux significatifs de troubles fonctionnels, principalement dans le domaine du fonctionnement scolaire. Les étudiants avec PTSD manifestent plus de plaintes somatiques, il en va de même pour les troubles fonctionnels. Les résultats montrent le sérieux impact psychologique d’un conflit violent et continuel sur les étudiants israéliens et palestiniens et signale le besoin de développer des interventions scolaires appropriées à leurs besoins en matière de santé mentale.
