The goal of the present study was to examine individual differences in the degree to which controlled attention is allocated towards a prospective memory (PM) task. Using a PM task that should require high levels of controlled attention in a sample of 138 young, middle-aged, and older adults, two subgroups of participants could be identified, i.e., participants who clearly demonstrated evidence for monitoring and those for whom no clear evidence for monitoring was revealed. A control group (n=95) was tested to control for practice effects in the ongoing task. Differences between subgroups were examined in terms of age, PM accuracy, baseline ongoing task performance, and general negative mood. Nonmonitorers and monitorers differed in age (more older adults being nonmonitorers), ongoing task accuracy (a nonsignificant trend was observed here), PM task accuracy (both young and middle-aged/older monitorers were more accurate than nonmonitorers), and the number of reported depressive symptoms (nonmonitorers > monitorers). Moreover, results showed that even in nonmonitorers PM accuracy was above floor level, indicating that noticing and reacting to some of PM cues is possible without strongly investing in resource demanding monitoring processes. 相似文献

ABSTRACTPrevious research demonstrated that relational processing in transitive inference problems can be disrupted by belief-based content. Given the premises, The horse is larger than the goat, and The goat is larger than the elephant, accepting the valid conclusion, The horse is larger than the elephant suggests use of relational processing whereas accepting the invalid conclusion The elephant is larger than the horse indicates belief-based responding. This research examined whether solving analogies influenced participants’ reliance on belief-based or relational processing. Participants generated solutions to either distant analogies (e.g. nose:scent::antenna: ______) or near analogies (e.g. nose:scent::tongue:______) before evaluating the conclusions of transitive inference problems that were valid (V) or invalid (I) and believable (B), unbelievable (U) or neutral (N). Solving distant analogies eliminated belief-based responding (possibly reflecting improved inhibitory control) and facilitated relational responding on VU problems. 相似文献

提取练习比建构概念图更有利于记忆保持和迁移的研究结果尚存在争议。依据认知负荷的3个成分,设计两个实验探究前期知识水平与策略复杂性对以上两种学习策略有效性的影响。结果表明:(1)前期知识水平的主效应不显著,但是与学习策略之间存在交互作用:在提取练习策略条件下,高前期知识水平的被试与低前期知识水平的被试在记忆保持和迁移上的正确率没有显著差异,但是在建构概念图策略条件下,高前期知识水平的被试在记忆保持和迁移上的正确率显著地高于低前期知识水平的被试;(2)当降低概念图的难度后,被试使用建构部分概念图策略产生的认知负荷与使用提取练习策略相比显著降低,并且其在学习阶段学习到的知识量显著地高于使用提取练习策略的结果,但是在最终测试上,其记忆保持与迁移的正确率与使用提取练习策略并没有显著差异,策略的复杂性增加了学习者的额外负荷,但是对策略有效性的发挥却不具有决定性影响。以上结果说明提取练习策略之所以比建构概念图策略更具优势,不是因为其策略本身更易掌握,而是因为其与建构概念图策略相比不受学习者前期知识水平的影响。这意味着认知负荷理论可以很好地解释提取练习在记忆保持与迁移中产生优势效应的内部机制,并进一步证实提取练习与精细编码不同,具有独特的加工机制。 相似文献

The paradoxical effects of intended thought suppression have been linked to psychological disorders, specifically anxiety disorders. So far, the evidence for thought suppression playing a major role in the disorder is mixed. One important issue is whether thought suppression is impaired only for thoughts related to the disorder, or if the ability for mental control is generally impaired in anxiety patients. This study compared groups of agoraphobics and social phobics with a healthy control group. All subjects were asked to suppress two topics related to the respective central fear of the two disorders and one nonspecific topic. We found a rather specific deficit in thought suppression for the agoraphobics; that is, when compared with the control group, we found the biggest differences for the agoraphobic fear. The social phobics seem to be characterized by a general impairment of mental control, affecting specific and nonspecific stimuli. In addition, among several psychopathological variables, social anxiety proved to be the strongest predictor for problems with thought suppression. Taken together, there are several indicators that generally impaired thought suppression may be an important feature of social phobia. 相似文献

Transformations in Therapeutic Practice 总被引:1,自引:0,他引:1
Stephen Smith 《Contemporary Family Therapy》2002,24(1):111-128
In her training of therapists, Virginia Satir sought to change the way her trainees perceived themselves, their clients, and the therapeutic endeavor. The change she sought was a movement from hierarchical models of therapy where clients were diagnosed in terms of paradigms of how they ought to be to an organic model where the therapist attempts to understand the client by entering the client's internal context. Contemporary training in the Satir model attempts to bring about the same change. Research indicates that the trainers are succeeding. 相似文献

汉语同音异形词意义识别中的抑制过程 总被引:1,自引:0,他引:1
使用被试自定步速逐词阅读的移动窗口技术,考察了视觉呈现的均衡型和偏向型两类汉语同音异形词意义识别中的抑制过程。实验要求被试阅读由三个分句组成的句子。重复条件下,句子第一个分句中的一个词与第三个分句中的一个词同音异形。同不重复条件(用控制词替换重复条件下第一个分句中的同音异形词)相比,重复条件下,被试对第三个分句中均衡型同音异形词之后的第一个区段阅读时间要长,即出现重复性效应。这种效应在偏向型同音异形词中并未出现。这一结果支持VHMR模型的抑制控制模块假设。简单的抑制假设或衰退假设均无法解释上述结果。此外,上述重复性效应仅出现在阅读速度较快的被试身上。这说明正是对无关信息的高效能的抑制,使得被试表现出较快的阅读速度。 相似文献

Understanding families as systems 总被引:2,自引:0,他引:2
In this article, we discuss recent research that has arisen from theoretical and conceptual models that use a systems metaphor for understanding families. We suggest that research stimulated by such models leads social scientists in new and important directions in understanding the social and emotional development of children in their families. These models view development as resulting from the dynamic transactions across multiple levels of family systems, which regulate a child's behavior. Thus, these models are important in considering multiple influences on development and adaptation. 相似文献

DNA作为生物遗传物质,它的发现是一个伟大的历史事件,具有所有科学发现的共性,回顾一个世纪的DNA发现的科学史,可以升华出许多的哲学观点和理论。经验和推理是科学赖以建立的两根支柱,一定历史条件下学科的交叉与渗透对科学发现有重大意义。分析科学的继承与DNA双螺旋结构的提出、DNA双螺旋发现中科学家的创造性思维及思维方式的选择等几个方面,旨在总结科学发展的经验,从而更加理性、主动地发展科学。 相似文献
