整体运动知觉老化伴随颞中回静息态功能改变 总被引:1,自引:0,他引:1
以个体整体运动一致性阈值为指标, 探讨老年人整体运动敏感性(GMS)下降和静息态下兴趣脑区功能活动的关系。发现与阈值负相关且老年人低于青年人的指标主要有:MT/V5区的ReHo和ALFF值, 各网络拓扑属性; 与阈值正相关且老年人显著高于青年人的有:MT/V5区与前运动皮层之间的、各兴趣脑区之间的功能连接。结果用“去分化”等观点进行了解释, 提示老年人GMS的下降可能不仅与安静状态下MT/V5区的功能改变有关, 还可能与全脑更广泛区域的功能改变有关。 相似文献

Social scientists have increasingly recognized the lack of diversity in survey research on American religion, resulting in a dearth of data on religion and spirituality (R/S) in understudied racial and ethnic groups. At the same time, epidemiological studies have increasingly diversified their racial and ethnic representation, but have collected few R/S measures to date. With a particular focus on American Indian and South Asian women (in addition to Blacks, Hispanic/Latinas, and white women), this study introduces a new effort among religion and epidemiology researchers, the Study on Stress, Spirituality, and Health. This multicohort study provides some of the first estimates of R/S beliefs and practices among American Indians and U.S. South Asians, and offers new insight into salient beliefs and practices of diverse racial/ethnic and religious communities. 相似文献

注意促进效应指学习阶段采用目标探测性质的二级任务,不仅不会降低同时呈现的背景信息的编码加工,反而会促进其记忆。为进一步探究对背景信息的编码意识是否会影响该效应,本研究设置了有意与无意两种编码条件,并引入“记得/知道”判断进一步将再认区分为回想和熟悉性。结果表明,无意编码下也会产生ABE,但不同的编码条件下,目标探测所促进的背景信息的编码加工存在差异。有意编码条件下,目标探测促进的更多是对背景信息的精细加工,而无意编码条件下,目标探测促进的更多是对背景信息的知觉加工。 相似文献

Social impairments are common across many psychiatric conditions. Standardized dyadic assessments intended to elicit social affiliation between unacquainted partners are used to elucidate mechanisms that disrupt relationship formation and inform possible treatment targets; however, the psychometric properties of such paradigms remain poorly understood. This study evaluated the psychometric properties of a controlled social affiliation paradigm intended to induce connectedness between a target participant and trained confederate. Individuals with an anxiety or depressive disorder diagnosis (clinical group; n = 132) and those without (control group; n = 35) interacted face-to-face with a trained confederate; partners took turns answering a series of increasingly intimate questions about themselves. Social connectedness, affect, and affiliative behavior measures were collected during the interaction. Participant symptom and social functioning measures were collected to examine validity. The paradigm elicited escalating social connectedness throughout the task for both participants and confederates. Parallel forms (i.e., different question sets) elicited similar affiliation outcomes. Self-reported (but not behavioral) affiliation differed across some demographic variables (e.g., participant gender, Hispanic ethnicity). Within-task affiliation measures were associated with one another and with global social connectedness and social anxiety symptom measures, but not with somatic anxiety measures. Clinical participants reported lower social affiliation and positive affect reactivity and higher negative affect reactivity than healthy participants. These findings provide initial psychometric support for a standardized and controlled dyadic affiliation paradigm that could be used to reliably probe social disconnection mechanisms across psychopathology. 相似文献

Attentional difficulties are a core axis in attention-deficit/hyperactivity disorder (ADHD). However, establishing a consistent and detailed pattern of these neurocognitive alterations has not been an easy endeavour. Based on a dimensional approach to ADHD, the present study aims at comprehensively characterizing three key attentional domains: the three attentional networks (alerting, orienting, and executive attention), two components of vigilance (executive and arousal vigilance), and distraction. To do so, we modified a single, fine-grained task (the ANTI-Vea) by adding irrelevant distractors. One hundred and twenty undergraduates completed three self-reports of ADHD symptoms in childhood and adulthood and performed the ANTI-Vea. Despite the low reliability of some ANTI-Vea indexes, the task worked successfully. While ADHD symptoms in childhood were related to alerting network and arousal vigilance, symptoms in adulthood were linked to executive vigilance. No association between ADHD symptom severity and executive attention and distraction was found. In general, our hypotheses about the relationships between ADHD symptoms and attentional processes were partially supported. We discuss our findings according to ADHD theories and attention measurement. 相似文献

Imaginal action: towards a Jungian conception of enactment,and an extraverted counterpart to active imagination 下载免费PDF全文
Robin S. Brown 《The Journal of analytical psychology》2018,63(2):186-206
This theoretical paper considers the fashion in which Jung's psychology radically challenges modern assumptions concerning the nature of subjectivity. With an eye for the clinical implications of Jung's late work, the author introduces the idea of imaginal action. In order to explain what is meant by this, the paper begins by exploring how Jung's thinking demonstrates an underlying bias towards introversion. It is argued that while Jung's interest in synchronicity ultimately resulted in his developing a worldview that might address the introverted biases of his psychology, the clinical implications of this shift have not been sufficiently clarified. With reference to some short examples from experience, the author outlines a conception of relational synchronicity wherein the intrapsychic emerges non‐projectively within the interpersonal field itself. Comparing and contrasting these occurrences to the more introverted practice of active imagination, it is claimed that such a notion is implicit in Jung's work and is needed as a corrective to his emphasis on interiority. The author suggests that imaginal action might be conceived as a distinctly Jungian approach to the psychoanalytic notion of enactment. It is also shown how the idea outlined might find further support from recent developments in the field of transpersonal psychology. 相似文献

This study aimed to describe and compare naming speed abilities in children diagnosed with either Reading Learning Difficulties (RLD) or Attention Deficit/Hyperactivity Disorder (ADHD), or comorbidity for both (ADHD+RLD). To examine the explanatory power of naming speed and ADHD symptomatology in predicting group associations (while controlling for gender and age), the “Rapid Automatized Naming and Rapid Alternating Stimulus Tests” (RAN/RAS) were utilized. A sample of 101 children (age range = 5–16 years) was divided into four groups: RLD (n = 14), ADHD (n = 28), comorbid (n = 19), and control (n = 40). There were statistically significant differences in RAN/RAS results among the diagnostic groups. Moreover, discriminant analysis revealed that naming speed tasks significantly predicted reading and attentional problems, especially at earlier ages. These results demonstrate the potential usefulness of RAN/RAS in the diagnosis of reading and attentional problems, particularly if the children are aged from 5 to 9. 相似文献

Positive Psychology Factors as Predictors of Latina/o College Students’ Psychological Grit 下载免费PDF全文
Javier Cavazos Vela Wayne D. Smith James F. Whittenberg Rebekah Guardiola Miranda Savage 《Journal of multicultural counseling and development》2018,46(1):2-19
Latina/o college students (N = 130) provided perceptions of psychological grit, presence of meaning in life, search for meaning in life, hope, life satisfaction, and mindfulness. Hope and mindfulness were significant predictors of psychological grit. A discussion regarding the importance of these findings and implications for counselors are presented. Un grupo de estudiantes universitarios latinos (N = 130) aportó sus percepciones de perseverancia psicológica, presencia de sentido en la vida, búsqueda de sentido en la vida, esperanza, satisfacción vital y atención plena. Se presenta una discusión sobre la importancia de estos hallazgos y sus implicaciones para los consejeros. 相似文献

This study examined the role of attention at retrieval on the false recognition of emotional items using the Deese–Roediger–McDermott (DRM) paradigm. Previous research has shown that divided attention at test increases false remember judgements for neutral critical lures. However, no research has yet directly assessed emotional false memories when attention is manipulated at retrieval. To examine this, participants studied negative (low in valence and high in arousal) and neutral DRM lists and completed recognition tests under conditions of full and divided attention. Results revealed that divided attention at retrieval increased false remember judgements for all critical lures compared to retrieval under full attention, but in both retrieval conditions, false memories were greater for negative compared to neutral stimuli. We believe that this is due to reliance on a more easily accessible (meaning of the word) but less diagnostic form of source monitoring, amplified under conditions of divided attention. 相似文献
