Fear-related processing in the amygdala has been well documented, but its role in signaling other emotions remains controversial. The authors recovered signal loss in the amygdala at high-field strength using an inward spiral pulse sequence and probed its response to pictures varying in their degree of portrayed sadness. These pictures were presented as intermittent task-irrelevant distractors during a concurrent visual oddball task. Relative to neutral distractors, sad distractors elicited greater activation along ventral brain regions, including the amygdala, fusiform gyrus, and inferior frontal gyrus. In contrast, oddball targets engaged dorsal sectors of frontal, parietal, and cingulate cortices. The amygdala's role in emotional evaluation thus extends to images of grief and despair as well as to those depicting violence and threat. 相似文献

清代中期“以礼代理”说刍议 总被引:1,自引:0,他引:1
清代中期,以凌廷堪、焦循、阮元为代表的汉学家提出了“以礼代理”说,即主张用礼学代替理学。他们认为,儒学的中心是“礼”而不是“理”,脱离了“礼”而言“理”,只能导致师心自用以及对人的具体情感的漠视。这一学说是清初顾炎武所倡导的学术方向的继续,它把人们的目光由内在精神变革转向对外在制度的关注;同时,这一学说明确反对以抽象化的“理”来约束人们的行为,它在一定程度上减轻了理学所带来的消极影响。 相似文献

Three experiments examined the role of three distinctive perceptual factors in recognition and recall memory. Using a subject-paced presentation rate, the first two experiments (recognition and recall) examined (1) the number of phonological-to-orthographic neighbors, (2) phonological-to-orthographic consistency, and (3) orthographic-to-phonological consistency. The third experiment (recall) reexamined the number of phonological-to-orthographic neighbors, using an experimenter-paced presentation rate of 2 sec per item. In both recognition and recall memory tasks, the number of phonological-to-orthographic neighbors influenced memory performance, whereas the two types of consistency did not. The results indicate that having fewer phonological-to-orthographic neighbors (i.e., having distinct mappings between orthography and phonology, and between phonology and orthography, e.g., pulp) relieve words from interference in episodic memory tests for such words. Furthermore, words that are indistinct in terms of these mappings (e.g., tuck) are subject to interference from words with similar representations (e.g., luck, buck, stuck), and this weakens the memory trace for a particular word. 相似文献

语篇理解中背景信息的激活: 情景限制的共振过程 总被引:3,自引:0,他引:3
该研究采用双人物线索语篇材料,对语篇理解中背景信息激活过程的共振模型与剧景模型进行检验。实验一发现,如果主角和配角一直同时在故事情景中成为主线索,则目标句中主角的行为可以激活那些经过屏蔽的、与这一行为相关的配角特征。在实验二中,配角只是在特征描述段落中出现,而后通过适当的描述使其在故事情景中消失,使主角成为故事的主线索,结果发现,此时目标句中主角的行为并不会激活经过屏蔽的配角的特征描述。这些结果表明,背景信息的激活虽然具有共振的特点,但共振并不是无范围限制的,而是一种情景限制下的共振。 相似文献

The emergence of cultural self-constructs: autobiographical memory and self-description in European American and Chinese children 总被引:6,自引:0,他引:6
Wang Q 《Developmental psychology》2004,40(1):3-15
This study examined the emergence of cultural self-constructs as reflected in children's remembered and conceptual aspects of the self. European American and Chinese children in preschool through 2nd grade participated (N=180). Children each recounted 4 autobiographical events and described themselves in response to open-ended questions. American children often provided elaborate and detailed memories focusing on their own roles, preferences, and feelings; they also frequently described themselves in terms of personal attributes, abstract dispositions, and inner traits in a positive light. Chinese children provided relatively skeletal accounts of past experiences that centered on social interactions and daily routines, and they often described themselves in terms of social roles, context-specific characteristics, and oven behaviors in a neutral or modest tone. Findings are discussed in light of the self as a constructed meaning system of culture that emerges early in life. 相似文献

In visual search tasks, if a set of items is presented for 1 s before another set of new items (containing the target) is added, search can be restricted to the new set. The process that eliminates old items from search is visual marking. This study investigates the kind of memory that distinguishes the old items from the new items during search. Using an accuracy paradigm in which perfect marking results in 100% accuracy and lack of marking results in near chance performance, the authors show that search can be restricted to new items not by visual short-term memory (VSTM) of old locations but by a limited capacity and slow-decaying VSTM of new locations and a high capacity and fast-decaying memory for asynchrony. 相似文献

Previous research has demonstrated that older adults are more susceptible than young adults to context-induced biases in social judgments. The primary goal of this study was to examine the conditions under which older adults could or could not correct their biases. Young and older adults completed a social judgment task that normally would produce contrast biases in 3 correction cue conditions: no cue, subtle cue, and blatant cue. It was found that both young and older adults corrected their biases in the blatant cue condition, but only young adults corrected in the subtle cue condition. The results suggest that older adults may need more environmental support in correcting their biases. 相似文献

The prevalence of dating violence, as well as its association with psychosocial factors, was examined among a nationally representative sample of 9th- through 12th-grade U.S. boys (N = 7,434) who completed the 1999 Youth Risk Behavior Survey. The dependent variable was physical dating violence; the independent variables were violence, suicide, substance use, and sexual risk behavior. Unadjusted odds ratios (OR) and 95% confidence intervals (CI) were examined. Multivariate logistic regression was used to examine all significant independent variables from the univariate models. Adjusted OR and 95% CI were examined to assess the significance of these relationships. In terms of prevalence, 9.13% of the boys reported physical dating violence. Boys who reported sad/hopeless feelings (OR = 1.68), had attempted suicide (OR = 2.22), reported fighting (OR = 1.81), had multiple sex partners (OR = 3.53), and reported nonuse of condoms (OR = 1.66) were more likely to report physical dating violence. These findings indicate that physical dating violence among adolescent boys may be a more serious problem than has previously been recognized. It was concluded that intervention programs should include a focus on boys as not only perpetrators but also recipients of dating violence. 相似文献

The prevalence of dating violence, as well as its relationship to potential risk factors, was examined among a nationally representative sample of 9th-through 12th-grade U.S. females (N = 7,824) who completed the 1999 Youth Risk Behavior Survey. The dependent variable was physical dating violence; the independent variables were violence, suicide, substance use, and sexual risk behavior. Unadjusted odds ratios (OR) and 95% confidence intervals were examined, and multivariate logistic regression analysis was conducted to identify the most significant risk factors. It was found that nearly one in ten of the adolescent girls reported dating violence. Twelfth-grade girls had the highest prevalence of dating violence. Girls who were victims of dating violence were more likely to be involved in other violent behaviors, to report extreme sadness and suicidal actions, to use illicit substances, and to engage in risky sexual behavior. Multivariate analysis revealed that dating violence was associated with sad/hopeless feelings (OR = 2.13), binge drinking (OR = 1.96), cocaine or inhalant use (OR = 2.90), multiple sex partners (OR = 2.38), nonuse of condoms (OR = 1.53), and ethnicity, specifically being Black (OR = 2.32) or Hispanic (OR = 1.82). These findings provide further evidence that there is a clustering of risk factors among certain adolescents, specifically girls who experience dating violence. 相似文献
