传统注意研究多基于单个注意焦点和采用静态视觉信息。由Pylyshyn(1988)提出的多目标追踪范式则基于动态场景,是研究同时追踪多个目标的容量有限的注意机制比较常用的范式。在多目标追踪基础上发展起来的多身份追踪范式中的对象带有身份信息,涉及到较复杂的认知机制,如注意、视觉工作记忆等。探讨以上两种视觉追踪的认知加工机制对真实或模拟情境中动态信息的认知加工活动有重要的理论价值和实践指导意义。  相似文献

繁殖群中婴幼川金丝猴社会关系发展的个案研究   总被引:7,自引:0,他引:7       下载免费PDF全文
使用瞬时取样法,对繁殖笼内出生的两只婴幼川金丝猴进行连续22个月的行为记录。结果表明,川金丝猴婴猴断乳大约在19—20月龄;断乳表现为母婴之间矛盾冲突的过程;群内其他雌性对初生婴儿表现出明显的抢婴、护婴和育婴行为;父亲对婴幼猴表现出接纳和容忍的态度;婴儿在断乳前是群内全体成员保护和爱护的对象,以后开始进入社会关系网,受到成年个体的责备,但很轻微;雌性幼猴在32月龄时尚未被记录到对群内成员表现威胁、蜷缩和匍伏等行为模式。  相似文献

系统考察在控制目标与非目标颜色特征属性的条件下, 动态非注意盲中视觉系统是否存在对分心物的抑制机制。实验一为基线实验, 将目标与非目标设置为相同的白色圆形, 考察被试对不同颜色特征(白色或者黑色)新异刺激的觉察情况; 实验二和实验三通过改变目标与非目标的颜色特征, 进一步探讨视觉系统对分心物(包括非目标和新异刺激)的抑制机制。结果发现, 视觉系统对干扰目标追踪(并计数)任务的分心物均产生抑制作用, 并且不同颜色特征的分心物受到的抑制作用不同, 与目标颜色特征相同的分心物受到的抑制作用较大, 相应新异刺激的觉察率低; 与目标颜色特征区分明显的分心物受到的抑制作用较小, 相应新异刺激的觉察率较高。  相似文献

父母低头行为对儿童青少年心理发展的影响   总被引:1,自引:0,他引:1       下载免费PDF全文
父母低头行为是指父母照顾或与孩子交流时,过分关注与使用手机而忽视孩子的行为。梳理相关研究发现,父母低头行为会对孩子产生多种不良影响,如,降低亲子关系交流质量、增加意外伤害风险、损伤人际交往能力、导致问题行为增多。现有研究采用取代假说、多任务操作理论以及依恋理论对影响过程进行解释。未来研究的关键在于邻近概念的区分、测量方式和研究方法的改进、探讨儿童对父母手机使用行为的看法以及移动设备对亲子互动可能的积极影响。  相似文献

护士职业精神是护士从业过程中所表现出的基本从业理念、价值取向、职业人格、职业准则及职业风尚的总和。“他者”是法国近代著名哲学家列维纳斯伦理学的核心概念,具有不同于“我”的绝对差异性、外在性和独特性。护士与患者的关系,一定程度上可以理解为“我”与“他者”的关系。从“他者”伦理视角探讨护士职业“他者”的精神内涵,通过分析临床中护士“他者”意识淡薄的具体表现,提出“他者”意识指导下护士职业精神的培养和提升路径:加强职业素养教育、营造人文护理氛围和深化护患沟通实践。  相似文献

乙型肝炎病毒(HBV)持续感染可导致多种严重的疾患,包括慢性肝炎、肝硬化和肝癌。在我国约有1.2亿HBV感染者。目前临床主导的抗HBV药物是干扰素(IFN)和拉米夫定(LAM)。据国内报道[1],治疗慢性乙肝,用IFN-α可使约10%病人HBeAg转阴。单用1年后,约15%出现耐药,常出现副作用。用拉米夫定可使约71%病人血中HBV DNA转阴,27%~40%的HBeAg转阴。用拉米夫定的疗程较长(1年以上),易产生耐药(1年后为20%,2年后为53%,3年后70%)。这主要是由于拉米夫定不能清除细胞核内以cccDNA(共价闭环DNA)形式存在的HBV。机体清除细胞核内的HBV cccDN…  相似文献

Emotions affects moral judgements, and controlled cognitive processes regulate those emotional responses during moral decision making. However, the neurobiological basis of this interaction is unclear. We used a graph theory measurement called participation coefficient (‘PC’) to quantify the resting-state functional connectivity within and between four meta-analytic groupings (MAGs) associated with emotion generation and regulation, to test whether that measurement predicts individual differences in moral foundations-based values. We found that the PC of one of the MAGs (MAG2) was positively correlated with one of the five recognized moral foundations–the one based on harm avoidance. We also found that increased inter-module connectivity between the ventromedial prefrontal cortex, dorsolateral prefrontal cortex and middle temporal gyrus with other nodes in the four MAGs was likewise associated with higher endorsement of the Harm foundation. These results suggest that individuals' sensitivity to harm is associated with functional integration of large-scale brain networks of emotional regulation. These findings add to our knowledge of how individual variations in our moral values could be reflected by intrinsic brain network organization and deepen our understanding of the relationship between emotion and cognition during evaluations of moral values.  相似文献

A recent line of research has investigated the frame‐of‐reference effect on personality scale scores, in which self‐report personality items are contextualized to the specific performance setting (e.g., work, school) within which the performance criterion is gathered. Contextualization has been shown to increase both the reliability and the criterion‐related validity of the personality scale scores by facilitating the self‐presentation of respondents, and by more closely measuring the personality construct relevant to the performance domain. The current research extends this area of personality research in two ways. First, this study tests the generalizability of the effectiveness of item‐level contextualization within an organizational setting. Second, this study also provides the necessary test of the incremental validity of this contextualized approach to personality measurement above and beyond the traditional, noncontextualized approach. The results confirm that a work‐specific personality measure, contextualized at the item level, adds to the prediction of job performance above and beyond that obtained by a noncontextual measure of the same personality traits. Practical and theoretical implications are discussed.  相似文献

Six experiments were performed to explore the necessary and sufficient conditions for producing context specificity of discriminative operant performance in pigeons. In Experiment 1, pigeons learned a successive discrimination (red S+/blue S−) in two chambers that had a particular odor present and between which they were frequently switched. The birds subsequently learned the reversal (blue S+/ red S−) in one of these chambers with a different odor present. When switched to the alternative chamber, although the odor and the reinforcement contingency were still appropriate to the reversal, performance appropriate to the original discrimination recurred in subjects for which the houselights were on during training and testing but not for those for which the houselights were off. This indicated the importance of visual contextual cues in producing context specificity. Experiment 2 showed that the frequent switching between boxes in initial training was of no consequence, presumably because the apparatus cues were highly salient to the subjects. Experiment 3 showed significantly less context specificity when odor cues were omitted. Experiment 4 showed that simply using a different reinforced stimulus in each phase of training was ineffective in producing context specificity. Experiment 5 showed that the generalization test procedure used in Experiment 4 was sensitive to context specificity when discrimination-reversal training was used with different odors in the two training phases. Experiment 6 replicated the results of Experiment 4, but then showed that when different odors accompanied the two training phases, context specificity was obtained with the single-stimulus paradigm. Thus in both single-stimulus and discrimination-reversal paradigms, redundant odor cues potentiated learning about apparatus cues.  相似文献

在智力的研究中,社会智力(social intelligence)和情感智力(emotional intelligence)是先后被心理学家提出的概念。本文试图对这两个概念出现及其相关研究进展过程进行回顾、总结和简单的评价,并提出以下一些未来可以进行探讨的问题:(1)就概念而言,社会智力和情感智力相互的关系究竟如何?(2)在智力的这一领域的研究中,概念的内涵究竟大一些好还是小一些好?(3)概念的提出,是重理论严谨性还是重应用性?(4)如何解决好的概念和研究思路与困难的理论构建和实际测量之间的矛盾?  相似文献
