This paper investigates the time it takes unconscious vs. conscious knowledge to form by using an improved "no-loss gambling" method to measure awareness of knowing. Subjects could either bet on a transparently random process or on their grammaticality judgment in an artificial grammar learning task. A conflict in the literature is resolved concerning whether unconscious rather than conscious knowledge is especially fast or slow to form. When guessing (betting on a random process), accuracy was above chance and RTs were longer than when feeling confident (betting on the grammaticality decision). In a second experiment, short response deadlines only interfered with the quality of confident decisions (betting on grammaticality). When people are unaware of their knowledge, externally enforced decisions can be made rapidly with little decline in quality; but if given ample time, they await a metacognitive process to complete. The dissociation validates no-loss gambling as a measure of conscious awareness. 相似文献

To examine the association of 1) race/ethnicity and 2) numeracy with awareness of DTC genetic tests. Secondary analysis of
6,754 Hispanic, black, and white adult respondents to the National Cancer Institute’s 2007 Health Information National Trends
Survey (HINTS). Logistic regression was used to examine sociodemographic predictors of DTC genetic tests awareness including
race/ethnicity, income, education, and gender. Next, two numeracy variables were added to the model. After controlling for
sociodemographic variables, black respondents were significantly less likely to have heard of DTC genetic tests compared to
white respondents (OR = 0.79; CI: 0.65–0.97). When numeracy variables were added to the model, the effect of black race was
no longer significant (OR = 0.84; CI: 0.69–1.04). Hispanic respondents did not significantly differ from white respondents
in awareness of DTC genetic tests. Other significant correlates of DTC genetic tests awareness in the full model included
education, income, age, and numeracy variables including degree to which people use medical statistics and numbers to make
health decisions, and preference for words or numbers when discussing “the chance of something happening.” Although black
respondents were generally less aware of DTC genetic tests than white respondents, this relationship appears to be partially
mediated by numeracy. 相似文献

Technological advances and information-seeking consumers have pushed forward the movement of direct-to-consumer (DTC) genetic
testing. Just like with other types of testing, there are potential risks, benefits and limitations. A major limitation of
DTC testing is the incomplete view it provides regarding lifetime risk for common, complex diseases, since most tests only
analyze 1–2 single nucleotide polymorphisms (SNPs) and do not include evaluation of medical or family histories, which is
necessary to risk assessment. Further, it is not currently well-established whether personal genomic testing results will
lead toward improved health behaviors, adverse psychological effects or potential overuse of the health care system. To display
these and other issues, we present an in-depth case study of an individual who ordered DTC genetic testing and subsequently
sought genetic counseling. This case presents a unique learning experience for the field of genomic counseling, as the patient
did not fit the typical assumptions regarding ‘early adopters’ of DTC testing. It also allowed the genetics health care providers
involved in the case to identify gaps in current genetic counseling practice that need to be filled and approaches to employ
for successful delivery of genomic counseling. Based on our experience, we developed practical recommendations for genomic
counseling, which include novel approaches to case preparation, use of electronic tools during the counseling session, and
focusing on education as the major component of the genomic counseling session, in order to provide patients with the knowledge
necessary to independently interpret and understand large amounts of genomic testing information provided to them. 相似文献

We investigated the relationship between conformative peer bullying and issues of peer conformity among adolescents. This
relationship is examined through the establishment of a mediated moderation model for conformative peer bullying using structural
equation modeling in a sample of 391 second-year middle school students in Seoul, South Korea. We found that peer pressure
and resistance to peer influence interact with one another to affect antisocial conformity, which then affects conformative
peer bullying, thereby establishing its mediated moderation effect. The results suggest that conformative peer bullying that
encourages and assists active bullies is affected by antisocial conformity; moreover, an individual’s capacity to resist peer
influence plays a protective role against peer conformity, and this must be acknowledged as a significant influence in conformative
peer bullying among adolescents. 相似文献

Few programs exist for after school care designed to support children with Autism Spectrum Disorder (ASD). Not only do parents often depend on after school care, but also children with ASD are likely to benefit from opportunities to generalize skills in an authentic setting and interact with typically developing peers. This lack of support occurs at a time during which there is increasing research and community awareness regarding the need for high quality after school programs to support typically developing children. This study investigates reported experiences with and needs for after school care by parents of children with ASD. Survey results (N = 54) revealed that the majority of parents surveyed desired after school programs within their child’s school but are often denied access to such services or received low quality care for their child in after school programs. Recommendations are provided for future research and program development. 相似文献

In the aftermath of several school shooting incidents in recent years, students’ perceptions of unsafe schools has been a
major concern for parents, teachers, school officials, school practitioners, and policy-makers. Using Bronfenbrenner’s ecological
systems framework, we examined the micro-, meso-, and exosystem level factors associated with perceptions of unsafe school
environments in a nationally representative sample of 10- to 15-year-old youth in the United States. We found that for the
socio-demographic characteristics, students who were older, male, and poor had increased risks of perceiving higher levels
of unsafe school environments. Within the microsystem of the family, our results indicate that parent-youth discussions of
school activities/events decreased the risk of students perceiving unsafe schools. All of the school environment variables—ease
of making friends, teachers’ involvement, observed weapon carrying, and school rule enforcement—were related in the expected
direction to students’ perceiving their schools as unsafe. At the mesosystem level, findings from our study demonstrate that
variables measuring parental school involvement were unrelated to perceptions of school safety. Finally, at the exosystem
level, we found that students’ perceptions of residing in a safer neighborhood and residence in a non-central city metropolitan
area, compared with a central city, decreased the odds of perceiving school environments as unsafe. School policy and practice
implications are discussed. 相似文献

In the present study, introductory-level German students read a simplified story and learned the meanings of new German words
by reading English translations in marginal glosses versus trying to infer (i.e., guess) their translations. Students who
inferred translations were given feedback in English or in German, or no feedback at all. Although immediate retention of
new vocabulary was better for students who used marginal glosses, students who inferred word meanings and then received English
feedback forgot fewer translations over time. Plausible but inaccurate inferences (i.e., those that made sense in the context)
were more likely to be corrected by students who received English feedback as compared with German feedback, providing support
for the beneficial effects of mediating information. Implausible inaccurate inferences, however, were more likely to be corrected
on the delayed vocabulary test by students who received German feedback as compared with English feedback, possibly because
of the additional contextual support provided by German feedback. 相似文献

A positive relationship between prior knowledge and item memory is a consistent finding in the literature. In the present
study, we sought to determine whether this relationship extends to episodic details that are present at the time of encoding,
namely source memory. Using a novel experimental design, we were able to show both between- and within-subjects effects of
prior knowledge on source memory. Specifically, the results revealed that the degree of prior knowledge positively predicted
memory for source specifying contextual details. In addition, by including two conditions in which attention was divided either
at encoding or retrieval, we were able to show that prior knowledge influences memory by affecting encoding processes. Overall,
the data suggest that a priori knowledge within a specific domain allows attentional resources to be allocated toward the
encoding of contextual details. 相似文献

The type of experience involved with an object category has been regarded as one important factor in shaping of the human
object recognition system. Laboratory training studies have shown that different kinds of learning experience with the same
set of novel objects resulted in different perceptual and neural changes. Whether this applies to natural real-world objects
remains to be seen. We compared two groups of observers who had different learning experiences with faces, using holistic
processing as a dependent measure. We found that, while ordinary observers had extensive individuation experience with faces
and displayed typical holistic face processing, art students who had acquired additional experience in drawing faces, and
thus in attending to parts of a face, showed less holistic processing than did ordinary observers. These results converge
with laboratory training studies on the role of type of experience in the development of different perceptual markers for
different object categories. It is thus insufficient to categorize expertise simply in terms of object domains (e.g., expertise
with faces). Instead, perceptual expertise should be classified in terms of the underlying process or task demand. 相似文献

We are constantly exposed to our own face and voice, and we identify our own faces and voices as familiar. However, the influence
of self-identity upon self-speech perception is still uncertain. Speech perception is a synthesis of both auditory and visual
inputs; although we hear our own voice when we speak, we rarely see the dynamic movements of our own face. If visual speech
and identity are processed independently, no processing advantage would obtain in viewing one’s own highly familiar face.
In the present experiment, the relative contributions of facial and vocal inputs to speech perception were evaluated with
an audiovisual illusion. Our results indicate that auditory self-speech conveys a processing advantage, whereas visual self-speech
does not. The data thereby support a model of visual speech as dynamic movement processed separately from speaker recognition. 相似文献
