We examined whether the broadened attentional scope would affect people's sad or depressed mood with two experiments, enlightened by the meaning of “seeing the big picture” and the broaden‐and‐build model. Experiment 1 (n = 164) is a laboratory‐based experiment, in which we manipulated the attentional scope by showing participants zoomed‐out or zoomed‐in scenes. In Experiment 2 (n = 44), we studied how depressed mood and positive and negative emotions were affected when participants watched distant versus proximal scenes for eight weeks in real life. Healthy participants in Experiment 1, who were induced to feel sad, could return to the baseline mood after having the broadened attention task but not after having the narrowed attention task, which indicated that immediate attention broadening manipulation could function as antidotes for the lingering effects of induced negative emotions. Participants with depressed mood in Experiment 2 showed reduced depressed mood, increased positive affect, and decreased negative affect after receiving attention broadening training compared to those receiving attention narrowing training. Our findings suggest a robust role of broadened attentional scope in relieving negative emotions and even mildly depressed mood in the long run. 相似文献

In the current research, we sought to examine the role of spatial frequency on the detection of threat using a speeded visual search paradigm. Participants searched for threat-relevant (snakes or spiders) or non-threat-relevant (frogs or cockroaches) targets in an array of neutral (flowers or mushrooms) distracters, and we measured search performance with images filtered to contain different levels (high and low) of spatial frequency information. The results replicate previous work demonstrating more rapid detection of threatening versus non-threatening stimuli [e.g. LoBue, V. & DeLoache, J. S. (2008). Detecting the snake in the grass: Attention to fear-relevant stimuli by adults and young children. Psychological Science, 19, 284–289. doi:10.1111/j.1467-9280.2008.02081.x]. Most importantly, the results suggest that low spatial frequency or relatively coarse levels of visual information is sufficient for the rapid and accurate detection of threatening stimuli. Furthermore, the results also suggest that visual similarity between the stimuli used in the search tasks plays a significant role in speeded detection. The results are discussed in terms of the theoretical implications for the rapid detection of threat and methodological implications for properly accounting for similarity between the stimuli in visual search studies. 相似文献

Inattentional blindness refers to the failure to detect the salient unexpected stimuli in one’s visual field when performing an attention-demanding task. The present study examined the detection of threats in a static inattentional blindness paradigm. And the detection rates of evolutionary and ontogenetic threats were compared. Participants counted the number of color words from among three (low load) or six (high load) items presented in a circular array. On the last of six trials, an unexpected threatening/neutral illustration was presented in the center of the array along with the task stimuli. Participants detection of the illustration were thus measured and analyzed. The results suggested that: (1) the threatening stimuli, both evolutionary and ontogenetic, were detected more frequently than non-threatening stimuli; (2) the unexpected illustrations were identified more frequently under low-load condition than under high-load condition; (3) even under high-load situation, the threatening illustrations were more frequently identified than neutral ones. Threats are more likely to be detected under inattentional blindness and perceptual load. 相似文献

人类胚胎干细胞研究伦理问题的调查和讨论 总被引:3,自引:0,他引:3
此次对各级医生进行关于人类胚胎干细胞研究伦理认知的调查研究,其目的是为制订相关的伦理准则提供认知依据,调查是在我国东西部二个城市的8家三级医院进行,采用随机抽样、自愿无记名填写信息表方法调查.调查结果表明,50%以上医生认为早期胚胎不是道德意义的人,70%以上医生对胚胎干细胞的研究表示支持.海峡两岸的医生由于有相同的文化根源,在对待胚胎干细胞研究的伦理观点及态度上极其接近. 相似文献

现代哲学的逻辑起点不是独断的外在实体,而是无需前提设定而直接自明给予的自我意识。自我主体问题成为连接笛卡尔和康德的一个核心问题。笛卡尔哲学的起点是我思故我在,康德哲学的核心是先验主体的知性为自然立法。康德通过对笛卡尔自我实体性的批判而把自我逻辑功能化, 相似文献

弗雷格认为,句子的断定力真正展现了逻辑学所关心的"真"。并且与语词"真"的冗余论一致,他认为日常语言中缺少与断定力相应的符号。然而,弗雷格却似乎在他所发明的概念文字中为断定力指派了一个特殊的符号:判断杠。本文试图论证,尽管弗雷格直至学术生涯的最后阶段仍然坚持将判断杠保留在其逻辑语言系统之中,但概念文字中的这一设计并不符合他关于逻辑与真之关系的模糊洞见。在论证的关键一步中,我们将借助于胡塞尔关于"信念变异"的学说来澄清"判断"与"断定"之间被弗雷格所忽视的区别。在此基础上,我们最后将简要地提示出对弗雷格关于逻辑与真之关系的模糊洞见进行解读的方向。 相似文献

We used the composite-face illusion and Navon stimuli to determine the consequences of priming local or global processing on subsequent face recognition. The composite-face illusion reflects the difficulty of ignoring the task-irrelevant half-face while attending the task-relevant half if the half-faces in the composite are aligned. On each trial, participants first matched two Navon stimuli, attending to either the global or the local level, and then matched the upper halves of two composite faces presented sequentially. Global processing of Navon stimuli increased the sensitivity to incongruence between the upper and the lower halves of the composite face, relative to a baseline in which the composite faces were not primed. Local processing of Navon stimuli did not influence the sensitivity to incongruence. Although incongruence induced a bias toward different responses, this bias was not modulated by priming. We conclude that global processing of Navon stimuli augments holistic processing of the face. 相似文献

By focusing on human virtues rather than the general morality of rational beings, Kant’s virtue theory presents systematic
arguments from the perspectives of reason and experiential emotion, norms and disposition, spirituality and humanity, etc.,
which is of great significance to an overall understanding of Kantian ethics, thus clarifying misunderstandings from the past
decades. 相似文献
