Olfaction is a Marker of Severity but Not Diagnosis in Anorexia Nervosa: a Systematic Review and Meta-Analysis

Neuropsychology Review - Researchers have examined if olfaction is a sensitive biomarker of anorexia nervosa, but considerable heterogeneity across studies makes it difficult to reach a consensus....     

Theorising the emerging green prosumer culture and profiling green prosumers in the green commodities market

This paper explores the phenomenon of green prosumption with a view to theorising the phenomenon and highlighting the challenges and opportunities this particular subculture creates for marketers of green commodities. Narratives of young green prosumers were gathered from 18 phenomenological in‐depth interviews. Capturing green prosumer experiences and subjective meanings, three thematic categories of green prosumption practices, (a) contraction, (b) control, and (c) creation, are postulated in the study. It also highlights several unforeseen challenges as well as a vast array of opportunities emerging from the three green prosumer segments identified in the study: semi‐green prosumers, empowered green prosumers, and liberated green prosumers. This study provides green commodity marketers with a set of recommendations to exploit opportunities in these largely untapped market segments.     

Using a Constant Family in Role-Plays for Training MFTs

Marriage and Family Therapy training programs use role-plays and simulations to train their students in interviewing skills and in various therapeutic models. A review of literature shows that these training tools do not allow student-therapists to experience therapy beyond the first session. This article presents a modified version of the role-play, in which a constant family is used in preparing student-therapists for clinical work. This article describes a training scenario using the constant family role play and includes feedback from student-therapists. The authors present the benefits, limitations, and potential training considerations that can enhance use of the constant family role play.     

自然物体分类的ERP研究

对事物进行分类的能力是人类的一种基本认知功能。该文主要就近年来自然物体分类的事件相关电位（ERP）研究情况进行综述。首先介绍与自然物体分类有关的ERP早晚期成分;接着讨论了快速视觉分类的加工机制,认为前馈机制在这种复杂分类任务的视觉加工过程中起重要作用;最后详细介绍了两个分离的视觉加工机制,认为自然物体的视觉分类在不同时程涉及不同机制：即首先是任务无关的早期知觉加工过程,其次是任务相关的、类别无关的加工机制,与被试的决策有关。也讨论了这两个分离的加工过程涉及的神经基础。     

Talking to a (Segregation) Wall: Intergroup Contact and Attitudes Toward Normalization Among Palestinians From the Occupied Territories

This article examines how Palestinians' intergroup contact experiences relate to their attitudes towards interactions with Israelis (i.e., normalization). We draw on four recent advances in intergroup contact literature. First, recent research indicates that positive contact can impede disadvantaged groups' motivation to challenge inequalities. Second, increased endorsement of normalization mediates this sedative effect of positive contact on motivation to resist in the West Bank. Third, negative contact has been related to increased motivation for social change. Fourth, institutions and societal norms shape the meaning of intergroup contact and its effect on intergroup relations. We hypothesize that negative experiences at checkpoints can act as reminders of institutionalized inequalities and thus attenuate sedative effects. Furthermore, we explore the contextual boundary conditions of such reminder effects. Analyses of cross-sectional survey conducted among a representative sample (N = 1,000) in the West Bank including Jerusalem showed that (1) positive intergroup contact related to normalization endorsement (sedative effect), (2) negative intergroup contact related to decreased normalization endorsement (mobilizing effect), and (3) negative contact experiences (at checkpoints) canceled out the effect of positive contact (reminder effect), but only in Jerusalem. Results suggest that the impacts of intergroup contact need to be interpreted in light of institutionalized forms of group inequality and segregation.     

非平衡双语者Stroop效应的时间进程

运用Stroop任务的SOA范式,考察中-英双语者干扰和易化效应的时间进程及程度,比较双语者认知控制和词汇通达的差异。结果发现,在中文条件下,干扰效应的峰值发生在SOA为-200ms时,在英文条件下,最大的干扰效应发生在SOA为-300 ms时,由此可见,干扰效应时间出现了负转换。在英文条件下,-400ms SOA引发了最大的易化效应,而中文条件下最大的易化效应发生在-300ms SOA。该研究表明,双语者没有表现出认知优势,在Stroop任务中受到了词汇通达的影响。     

Measuring stress responses in postpartum mothers: perspectives from studies in human and animal populations

Reduced hypothalamic-pituitary-adrenal (HPA) responses to stress during the last week of pregnancy and lactation have been consistently observed in rat studies. Several contributing factors have been proposed for this phenomenon in lactation, including the suckling stimulus from the pups, hormones (oxytocin and prolactin) and opioids, a decrease in the ability of noradrenaline to potentiate hypothalamic responses and changes in pituitary responsiveness to ACTH secretagogues (AVP and CRF). In contrast to this vast literature using the rat model, only few studies have addressed this issue in the human population. The consensus is that women engaging in breastfeeding activities exhibit reduced anxiety, although the reductions in neuroendocrine and autonomic responses to stressors are variable, in part because of the different nature of the stressors used. Further work is required to investigate how additional factors, such as maternal parity or emotional salience of the stressor can affect stress responsiveness in postpartum women. Here, we review first the findings regarding stress responsiveness during lactation in both rat and human studies, and then discuss potential research avenues and methodological issues that could be the lead to future research protocols in human subjects. Knowing the reciprocal relationship in the mother-infant dyad, it is clear that investigation of the mechanisms regulating stress responses and mental health in postpartum mothers can only be beneficial to the development of the infant.     

Nanoindentation-induced elastic–plastic transition and size effect in α-Al2O3(0001)

The mechanical properties of α-Al₂O₃(0001) have been investigated using the technique of nanoindentation with a Berkovich indenter. Coupled with the Hertzian contact theory, a theoretical shear strength of 28?±?2?GPa was determined from the onset of pop-in events on load–displacement curves during loading, and the intrinsic hardness 30?±?3?GPa was obtained by analysis of the so-called indentation size effect, based on the concept of geometrically necessary dislocations. The predicted values of the shear strength, hardness and elastic modulus are in good agreement with available experimental data. The importance of experimentally calibrating the area function over the contact depth range prior to nanoindentation tests is emphasized.     

What is the Cause of Confidence Inflation in the Life Events Inventory (LEI) Paradigm?

Briefly imagining, paraphrasing, or explaining an event causes people to increase their confidence that this event occurred during childhood—the imagination inflation effect. The mechanisms responsible for the effect were investigated with a new paradigm. In Experiment 1, event familiarity (defined as processing fluency) was varied by asking participants to rate each event once, three times, or five times. No inflation was found, indicating that familiarity does not account for the effect. In Experiment 2, richness of memory representation was manipulated by asking participants to generate zero, three, or six details. Confidence increased from the initial to the final rating in the three- and six-detail conditions, indicating that the effect is based on reality-monitoring errors. However, greater inflation in the three-detail condition than in the six-detail condition indicated that there is a boundary condition. These results were also consistent with an alternative hypothesis, the mental workload hypothesis.
