We examined whether semantic processing occurs without awareness using continuous flash suppression (CFS). In two priming tasks, participants were required to judge whether a target was a word or a non-word, and to report whether the masked prime was visible. Experiment 1 manipulated the lexical congruency between the prime-target pairs and Experiment 2 manipulated their semantic relatedness. Despite the absence of behavioral priming effects (Experiment 1), the ERP results revealed that an N4 component was sensitive to the prime-target lexical congruency (Experiment 1) and semantic relatedness (Experiment 2) when the prime was rendered invisible under CFS. However, these results were reversed with respect to those that emerged when the stimuli were perceived consciously. Our findings suggest that some form of lexical and semantic processing can occur during CFS-induced unawareness, but are associated with different electrophysiological outcomes.  相似文献

This paper draws on information from the Fragile Families Study (N = 2,695) to examine how different coparenting styles emerge and are related to fathers' involvement with young children in a representative sample of unmarried parents. The results show that the quantity and quality of paternal involvement is significantly higher when unmarried parents establish a cooperative as opposed to a disengaged or conflicted coparenting style. Cooperative coparenting is less likely, however, when unmarried parents have separated after the birth or were never together as a couple, when fathers are unemployed or have other risk factors, when the child has a more difficult temperament, and when parents have fewer children together. This analysis also helps clarify previously equivocal findings concerning the relationship between coparenting conflict and paternal involvement. Regression results show that paternal involvement is not significantly different among parents with cooperative and mixed coparenting styles, indicating that when unmarried parents can work together and support each other's parenting efforts, even if they argue frequently while doing so, fathers remain more involved. At the same time, conflicted coparenting leads to a larger decrease in father involvement than disengaged coparenting. In the context of poorer‐quality coparenting relationships, it was conflict that mattered for fathering, not just parents' inability to cooperate. Implications of these findings for parenting education programs are discussed.  相似文献

采用事件相关电位技术和三类刺激的经典oddball范式,以内隐的方式探讨外倾特质个体的自我参照加工程度效应及其神经机制。实验发现,外倾被试的高自我相关名字在各个ERP成分上都比其他刺激诱发了更大波幅。在P2上,高自我相关的刺激比其他刺激诱发了更大的P2波幅和更长的P2潜伏期,其中中线脑区的效应最大。在N2上,高自我相关的刺激比其他刺激诱发了更大的N2波幅和更短的N2潜伏期,其中额区位置的效应最大。控制组被试的高自我相关名字比外倾型被试的高自我相关名字诱发了更大的N2的波幅和更短的N2潜伏期。在P3平均波幅上,高自我相关的刺激比其他刺激诱发了更大的P3波幅,其中中线效应最大。对比外倾型被试,控制组被试的自我参照刺激诱发了更大的P3波幅。研究结果表明外倾特质个体的自我参照加工具有程度效应,但对比控制组被试,外倾特质个体的自我参照加工的程度效应更弱。  相似文献

研究表明低自尊个体对负性信息表现出高度的警觉和关注,而高自尊个体相对来说注意积极地方面,但并未表现明显偏向。为了精确记录注意选择神经加工时间进程,进一步从电生理学角度对低自尊个体的负性注意偏向进行探讨,本研究运用事件相关电位(ERP)技术对不同自尊个体在点-探测任务过程中的注意偏向进行研究。实验一以129名在校大学生作为被试,以大学生面孔情绪图片(高兴、悲伤和中性)作为实验材料,结果发现,高低自尊个体之间没有出现注意偏向的差异。实验二以实验一筛选出的30名高低自尊个体作为被试,选择了更具负性情绪唤醒的愤怒图片作为实验材料(高兴、愤怒和中性),行为数据结果发现,两组被试都没有出现注意偏向,相反,无论是在高兴面孔条件下还是在愤怒面孔条件下,低自尊个体的反应时都快于高自尊个体;电生理学数据结果发现,在低自尊个体中,在两种情绪面孔条件下,有效线索的P1峰值显著高于无效线索,而无效线索的N2pc峰值显著高于有效线索。电生理学数据表明,无论是负性的还是正性的情绪性的信息都能引起低自尊个体的更多注意,表明低自尊个体更容易受到情绪性信息的影响。  相似文献

This essay addresses moral hazards associated with the emerging doctrine of the Responsibility to Protect (R2P). It reviews the broad acceptance by the Vatican and the World Council of Churches of the doctrine between September 2003 and September 2008, and attempts to identify grounds for more adequate investigation of the moral issues arising. Three themes are pursued: how a changing political context is affecting notions of sovereignty; the authority that can approve or refuse the use of force; and plural foundations for human rights in a religiously and otherwise plural world such that the human rights protection does not become tyrannical.  相似文献

Infant mental health practice requires the performance of intense emotional labor. Professionals comprising the infant mental health (IMH) field are largely women at seminal points in adult life‐span development. The purpose of this article is to explore the day‐to‐day challenges faced by clinical infant mental health professionals and their perspectives on the supports available for effective job performance. We review reflective supervision as a long‐cherished professional support in the IMH field designed to hold the practitioner's fears, worries, and ambivalence, so that she may return to the work fortified to remain in therapeutic alliance with families despite unsolvable problems and an unknowable future (Weatherston, D., 2009). Yet, we propose that reflective supervision alone may not be an adequate protective measure for a workforce performing intensive emotional labor for extended periods and therefore at potentially increased risk for burnout and high turnover (Hochschild, A.R. 1983 ; C. Maslach, 1982 , C.M. Brotheridge & A.A. Grandey, 2009; A.S. Wharton, 2009 ). We suggest that structural factors concerning organizational culture, flexibility in scheduling, and professional growth and versatility bear deeper examination for their merits in supporting the IMH workforce. Finally, we contend that the overrepresentation of women in practitioner positions in IMH leaves an empirical gap where little is known about the experience of male IMH practitioners and the ramifications of their performance of emotional labor.  相似文献

Despite widespread belief in the early childhood field of the benefits of reflective supervision, there has been limited empirical evidence to support the effectiveness of reflective supervision for home visitors and the children and families they serve. The present study examined the psychometric properties of four adapted self‐report measures assessing supervisors’ reflective supervision capacities; the study also investigated whether these measures captured change in reflective capacity over time as supervisors participated in professional development activities focused on reflective supervision. Results from 33 participants (home visiting supervisors and program managers) suggested that three of the four measures demonstrated acceptable internal consistency, and these three measures were correlated with each other. Two of these measures also captured significant change over time. Finally, there was some evidence that those with less education demonstrated more substantial improvement in their reflective supervision capacities than did those with an advanced degree. Findings provide initial evidence for reliable, efficient, and cost‐effective supervisor self‐report measures that could be used in research and program evaluation to assess change in supervisor reflective capacity over time.  相似文献

This cross-sectional study aimed to investigate the relationship between glycosylated haemoglobin (HbA1c) and cognitive vulnerability to depression (dysfunctional attitudes) in patients with type 2 diabetes mellitus. A total of 245 valid records from June 2016 to December 2016 were collected from a hospital in Beijing. Participants were asked to complete four questionnaires (Dysfunctional Attitudes Scale, Automatic Thoughts Questionnaire, Zung Self-rating Depression Scale, and World Health Organization Quality of Life Instrument-Short Form) to assess mental health and quality of life. Multivariate regression analysis was conducted to determine the correlations between HbA1c, mental health, quality of life and other clinical variables. The results showed that dysfunctional attitudes were associated with HbA1c, with a standardized regression coefficient (β) of .13 (p = .01), although 1 h C-peptide (β = ?.75, p < .0001) was the most significant predictor of HbA1c in the regression model. The results indicated that dysfunctional attitudes, as a cognitive vulnerability to depression, were a relevant factor in HbA1c, although further studies are needed to establish the nature of the connection between dysfunctional attitudes and glycaemic control in diabetes patients.  相似文献
