姑息治疗在提高晚期癌症患者生活质量、实施临终关怀、给予病人及其家属全面周到的照顾诸方面起着重要作用。在台湾,已为姑息治疗立法并实施了10年,积累了丰富的经验。这项法律本身及其细则、附件等配套文件使姑息治疗更加规范可行。研究规范的姑息治疗及台湾的相关法律可以帮助我们更好的理解姑息治疗的理念,帮助发展大陆同道构建有效实用的... 相似文献

晚正成分能够反映不同效价和不同唤醒度的情绪。作为后悔的一种现象,作为效应是否与晚正成分具有关联是研究关心的问题。采用运气轮博弈的范式,记录与分析被试在“做”与“不做”决策下的ERPs。研究发现,决策结果的正误显著影响了FRN、P300和LPC的波幅大小。作为类别对FRN、P300和LPC波幅的影响受到不同决策结果的影响,在决策正确的条件下,作为类别对FRN、P300和LPC波幅不产生影响,而在决策错误的条件下,作为类别对FRN、P300和LPC波幅产生了显著的影响。结果表明作为效应不仅影响了FRN、P300的波幅,同时也影响了LPC的波幅,将来研究应进一步探明晚正成分与后悔的密切关联。 相似文献

A scandal can evoke public outrage when it is widely publicized and involves an individual who is perceived to have a high level of cultural representativeness. Two experiments showed that when the scandalous target's moral character was highlighted, emotional responses towards the target were least negative when the scandal was widely circulated and when the target was seen as a representative of his culture. These results suggest that when a cultural symbol is implicated in a widely‐circulated scandal, the negative emotions directed towards the scandalous individual can be alleviated when the public remains confident in his or her commitment to morality. 相似文献

羊群行为是消费市场上的一种典型现象,它是指在不确定情境中,消费者模仿他人进行消费决策的行为。本研究通过模拟消费情境对消费者羊群行为的心理机制进行研究。研究1通过操纵观点的强弱研究消费者的信息加工方式。结果发现,消费者的羊群行为是消费者采用一致性启发式或能力启发式的结果。研究2进一步通过操纵群体内部的一致性程度考察两种启发式的作用条件。结果表明,在群体内部一致性程度高的情况下,消费者倾向于采用一致性启发式,与大众决策保持一致;在群体内部一致性低的情况下,消费者倾向于采用能力启发式,与专家的决策保持一致。 相似文献

摘要:采用3D模拟驾驶情景结合眼动技术探讨音乐节奏和歌词语言熟悉程度对驾驶行为和眼动规律的影响,研究结果表明:(1)驾驶经验对驾驶行为及眼动影响显著,新手与老手相比速度更慢、错误数更多;(2)音乐节奏对驾驶速度、眼跳和垂直搜索广度影响显著,快节奏与慢节奏相比,驾驶速度更快、平均眼跳距离更短、垂直搜索广度更短;(3)歌词语言熟悉程度对驾驶速度、错误数和平均注视时间影响显著,熟悉语言与陌生语言相比,驾驶速度更慢、错误数更多、平均注视时间新手更长,老手无影响。(4)节奏与语言共同影响驾驶过程中的水平搜索广度,陌生语言时快节奏的水平搜索广度高于慢节奏,熟悉语言时快节奏的水平搜索广度低于慢节奏。通过本实验,建议驾驶员在选择音乐时选择陌生语言歌词的音乐,音乐节奏则可视情况而定。 相似文献

Organization of visual short-term memory 总被引:11,自引:0,他引:11
Jiang Y Olson IR Chun MM 《Journal of experimental psychology. Learning, memory, and cognition》2000,26(3):683-702
The authors examined the organization of visual short-term memory (VSTM). Using a change-detection task, they reported that VSTM stores relational information between individual items. This relational processing is mediated by the organization of items into spatial configurations. The spatial configuration of visual objects is important for VSTM of spatial locations, colors, and shapes. When color VSTM is compared with location VSTM, spatial configuration plays an integral role because configuration is important for color VSTM, whereas color is not important for location VSTM. The authors also examined the role of attention and found that the formation of configuration is modulated by both top-down and bottom-up attentional factors. In summary, the authors proposed that VSTM stores the relational information of individual visual items on the basis of global spatial configuration. 相似文献

This study's purpose was to develop a reliable and valid self-report questionnaire, the Child-Adolescent Suicidal Potential Index (CASPI), to screen for risk for suicidal behavior in children and adolescents. Four hundred twenty-five child and adolescent psychiatric patients and nonpatients completed the CASPI and other research instruments to rate suicidal and assaultive behavior and symptoms of depression, anxiety, and hopelessness. The 30-item CASPI involves 3 factors (anxious-impulsive depression, suicidal ideation or acts, family distress) that contributed to a unidimensional 2nd-order factor accounting for 59% of the total variance. Internal consistency (alpha) for the total score was .90, and test-retest reliability (ICC) for the total score was .76. Total score distinguished between children and adolescents with different severity of psychopathology and different levels of suicidal and assaultive behavior. Each of the 3 factors had different contributions to discriminating between levels of suicidal status. CASPI total score of 11 distinguished suicidal ideation or acts from nonsuicidal behavior, with sensitivity 70% and specificity 65%. CASPI total score positively correlated with symptom severity of depression, anxiety, and hopelessness. 相似文献

Sensory adaptation and visual aftereffects have long given insight into the neural codes underlying basic dimensions of visual perception. Recently discovered perceptual adaptation effects for complex shapes like faces can offer similar insight into high-level visual representations. In the experiments reported here, we demonstrated first that face adaptation transfers across a substantial change in viewpoint and that this transfer occurs via processes unlikely to be specific to faces. Next, we probed the visual codes underlying face recognition using face morphs that varied selectively in reflectance or shape. Adaptation to these morphs affected the perception of "opposite" faces both from the same viewpoint and from a different viewpoint. These results are consistent with high-level face representations that pool local shape and reflectance patterns into configurations that specify facial appearance over a range of three-dimensional viewpoints. These findings have implications for computational models of face recognition and for competing neural theories of face and object recognition. 相似文献
