Adults are better at recognizing familiar faces from the internal facial features (eyes, nose, mouth) than from the external facial features (hair, face outline). However, previous research suggests that this “internal advantage” does not appear until relatively late in childhood, and some studies suggest that children rely on external features to recognize all faces, whether familiar or not. We use a matching task to examine face processing in 7-8- and 10-11-year-old children. We use a design in which all face stimuli can be used as familiar items (for participants who are classmates) and unfamiliar items (for participants from a different school). Using this design, we find an internal feature advantage for matching familiar faces, for both groups of children. The same children were then shown the external and internal features of their classmates and were asked to name or otherwise identify them. Again, both age groups identified more of their classmates correctly from the internal than the external features. This is the first time an internal advantage has been reported in this age group. Results suggest that children as young as 7 process faces in the same way as do adults, and that once procedural difficulties are overcome, the standard effects of familiarity are observed. 相似文献

Toward a predictive model of suicidal ideation and behavior: some preliminary data in college students 总被引:4,自引:0,他引:4
Within a multivariate statistical design, the relationship of various interpersonal, emotional, and cognitive variables to suicidal ideation and behavior in college students was examined. A total of 158 subjects (58 males, 100 females) completed self-report measures of life stress, faulty cognitions, loneliness, depression, hopelessness, family cohesiveness, adaptive reasons for living, and suicidal ideation and behavior. The results of a multiple-regression analysis, forward-inclusion algorithm, indicated that a predictive equation consisting of loneliness, irrational beliefs, and low adaptive reasons for living best accounted for suicidal behavior scores. To determine the basic structures and power of the predictor variables under study, a factor analysis and composite regression were employed, resulting in a predictive equation consisting of three factors: Social/Emotional Alienation, Cognitive Distortions, and Deficient Adaptive Resources. Results are discussed in terms of an interactional model of suicidal behavior. 相似文献

Two experiments are reported in which subjects made judgments about the sex or the familiarity of a voice. In experiment 1, subjects were fans of the BBC-radio soap opera, The Archers, and familiar voice clips were taken from this programme. Subjects showed a large reduction in response times when making sex judgments to familiar voices, despite the fact that sex judgments are generally much faster than familiarity judgments. In experiment 2, the same familiar clips were played to subjects unfamiliar with the soap opera, and no difference was observed in times to make sex judgments to Archers or non-Archers voices. We conclude that, unlike the case of face recognition, sex and identity processing of voices are not independent. The findings constrain models of person recognition across multiple modalities. 相似文献

The field of genetic counseling faces a broad challenge: many potential clients may not be aware of the value and benefit
of genetic counseling services, and therefore may not utilize those services. Navigenics is a personal genomic testing company
that provides telephonic genetic counseling services for multifactorial diseases and pharmacogenetics. When first offered
in 2008, utilization of the Navigenics genetic counseling service was less than expected. To explore the basis for under-utilization
and potential mechanisms for increasing uptake, Navigenics initiated a quality improvement study, in which three different
methods of engaging clients in the uptake of genetic counseling services were assessed over the course of 1 year. Outcomes
showed significant differences in uptake rates between methodologies (7.5%, 24.6%, and 60.1%), yielding an 8-fold increase
in service utilization when post-test telephonic outreach to all clients was performed. Further, utilization spanned all risk
levels based on client results, evidence that not only clients with high-risk results were motivated to engage in the genetic
counseling service. This research indicates that implementing strategies to educate clients about genetic counseling can positively
impact client engagement and utilization of available services. 相似文献

Belief revision is the problem of finding the most plausible explanation for an observed set of evidences. It has many applications in various scientific domains like natural language understanding, medical diagnosis and computational biology. Bayesian Networks (BN) is an important probabilistic graphical formalism widely used for belief revision tasks. In BN, belief revision can be achieved by finding the maximum a posteriori (MAP) assignment. Finding MAP is an NP-Hard problem. In previous work, we showed how to find the MAP assignment in BN using High Order Recurrent Neural Networks (HORN) through an intermediate representation of Cost-Based Abduction. This method eliminates the need to explicitly construct the energy function in two steps, objective and constraints. This paper builds on that previous work by providing the theoretical foundation and proving that the resultant HORN used to find MAP is strongly equivalent to the original BN it tries to solve. 相似文献

This article addresses three questions. To what extent does the current refugee regime discriminate among refugees? When is such discrimination wrong? Could discrimination ever be justified pragmatically, for the sake of admitting more refugees given political constraints? In answer to the first question, it finds discrimination is rampant. There is the kind of discrimination that gets noticed: discrimination that states choose to enact within the refugee regime. But there is also a kind of discrimination that is missed: discrimination that is a product of the regime itself. The second question proves tricky. Matters are clear at the extremes. Discrimination based on need is permissible. Discrimination based on race or religion is not. In between, we have a set of hard cases that are more difficult to judge. The article searches for relevant criteria. Finally, on the last question, the article concludes that a political leader could be justified in enacting discrimination as a pragmatic response to political constraints but that, even on such occasions, discrimination remains wrongful. 相似文献

Many theorists propose two types of processing: heuristic and analytic. In conflict tasks, in which these processing types
lead to opposing responses, giving the analytic response may require bothdetection andresolution of the conflict. The ratio bias task, in which people tend to treat larger numbered ratios (e.g., 20/100) as indicating a
higher likelihood of winning than do equivalent smaller numbered ratios (e.g., 2/10), is considered to induce such a conflict.
Experiment 1 showed response time differences associated with conflict detection, resolution, and the amount of conflict induced.
The conflict detection and resolution effects were replicated in Experiment 2 and were not affected by decreasing the influence
of the heuristic response or decreasing the capacity to make the analytic response. The results are consistent with dual-process
accounts, but a single-process account in which quantitative, rather than qualitative, differences in processing are assumed
fares equally well in explaining the data. 相似文献
