Although memory for the identities of examined items is not used to guide visual search, identity memory may be acquired during visual search. In all experiments reported here, search was occasionally terminated and a memory test was presented for the identity of a previously examined item. Participants demonstrated memory for the locations of the examined items by avoiding revisits to these items and memory performance for the items’ identities was above chance but lower than expected based on performance in intentional memory tests. Memory performance improved when the foil was not from the search set, suggesting that explicit identity memory is not bound to memory for location. Providing context information during test improved memory for the most recently examined item. Memory for the identities of previously examined items was best when the most recently examined item was tested, contextual information was provided, and location memory was not required.  相似文献

Little is known about genetic service utilization and ovarian cancer. We identified the frequency and outcome of genetic counseling referral, predictors of referral, and referral uptake for ovarian cancer patients. Using pathology reports, we identified all epithelial ovarian cancer patients seen in a university gynecologic oncology clinic (1/04–8/06). Electronic medical records (EMR) were used to document genetic service referral, time from diagnosis-to-referral, point-in-treatment at referral, personal/family cancer history, demographics, and genetic test results. Groups were compared using chi-squared and Fisher’s exact test for categorical variables and t-tests for continuous variables. The study population consisted of 376 women with ovarian cancer, 72 (19 %) of who were referred for genetic counseling/testing, primarily during surveillance. Of those referred, 42 (58 %) had personal or family genetic counseling and 34 (47 %) were ultimately tested or identified due to known family mutation. Family history and prior cancer were associated with referral. Family history, living in a larger community, higher-stage disease, and serous histology were associated with undergoing genetic counseling. Risk assessment identified 20 BRCA1/2 (5.3 %) and 1 HNPCC (0.3 %) mutation carriers. Based on recent estimates that 11.7–16.6 % of women with ovarian cancer are BRCA carriers and 2 % are HNPCC carriers, results suggest under-identification of carriers and under-utilization of genetic services by providers and patients. Interventions to increase medical providers’ referrals, even in a specialized oncology clinic, are necessary and may include innovations in educating these providers using web-based methods. Ease of referral by the introduction of an electronic cancer genetic referral form represents another new direction that may increase genetic risk assessment for high-risk women with ovarian cancer.  相似文献

The question of whether words can be identified without spatial attention has been a topic of considerable interest over the last five and a half decades, but the literature has yielded mixed conclusions. The present experiments manipulated the proportion of valid trials (the proportion of trials in which a cue appeared in the same location as the upcoming target word) so as to encourage distributed (50% valid cues; Experiments 1 and 3) or focused (100% valid cues; Experiments 2 and 4) spatial attention in a priming-type paradigm. Participants read aloud a target word, and the impact of a simultaneously presented distractor word was assessed. Semantic and orthographic priming effects were present when conditions promoted distributed spatial attention but absent when conditions promoted focused spatial attention. In contrast, Experiment 5 yielded a distractor word effect in the 100% valid cue condition when subjects identified a colour (Stroop task). We take these results to suggest that (1) spatial attention is a necessary preliminary to visual word recognition and (2) examining the role of spatial attention in the context of the Stroop task may have few implications for basic processes in reading because colour processing makes fewer demands on spatial attention than does visual word recognition.  相似文献

Theory of mind and its development has been a significantly important—and challenging—topic of research in cognitive science for three decades. This review summarizes our knowledge of when and how children come to understand their own and others' minds, including the developmental timetable, old and new measures, and foundational skills in infancy. We review recent research on theory‐of‐mind (ToM) and learning, that is, ways in which children's understanding of other minds informs how they learn about the world, as well as evidence for an important role of domain‐general cognitive skills (executive function) in the development of ToM, and the neural networks that are most strongly implicated. Finally, we propose future directions for research in this vast and growing field. WIREs Cogn Sci 2013, 4:391–402. doi: 10.1002/wcs.1232 This article is categorized under:

We evaluated the preliminary effectiveness of a novel intervention that was developed to address combat stress injuries in active-duty military personnel. Adaptive disclosure (AD) is relatively brief to accommodate the busy schedules of active-duty service members while training for future deployments. Further, AD takes into account unique aspects of the phenomenology of military service in war in order to address difficulties such as moral injury and traumatic loss that may not receive adequate and explicit attention by conventional treatments that primarily address fear-inducing life-threatening experiences and sequelae. In this program development and evaluation open trial, 44 marines received AD while in garrison. It was well tolerated and, despite the brief treatment duration, promoted significant reductions in PTSD, depression, negative posttraumatic appraisals, and was also associated with increases in posttraumatic growth.  相似文献

Healthy Steps for Young Children (HS) is a program designed to enhance pediatric primary care experiences for children birth to 3 years and their families by pairing a developmental specialist with a pediatric provider during well‐child visits. This study examined the impact of HS on content discussed during well‐child visits by providers, HS Specialists, and families. The impact of HS on pediatric outcomes, including timeliness of well‐child visits and immunizations, also was examined. Using retrospective medical review, records of 40 children enrolled in HS were compared with records of 36 demographically matched controls. A developmental topics checklist was used to analyze content of well‐child visits. Attendance at well‐child visits, receipt of immunizations, and healthcare utilization also was evaluated. Important developmental topics were discussed more often during well‐child visits of children enrolled in HS than for children who were not enrolled. Children enrolled in HS received timelier well‐child visits and immunizations. No differences between groups were found in the number of sick or emergency room visits. Integrating HS Specialists into pediatric primary care well‐child visits allows for discussion of important developmental topics while also impacting pediatric health outcomes.  相似文献

As US demographic trends shift toward more diversity, it becomes increasingly necessary to address differential needs of diverse groups of youth in mental health service systems. Cultural and linguistic competence (CLC) is essential to providing the most appropriate mental health services to youth and their families. The successful implementation of CLC often begins at the system level. Though various factors may affect change and system-level factors set the tone for broad acceptance of CLC within systems, there is limited empirical evidence linking culturally competent practices to outcomes. The purpose of the present study was to examine system-level CLC changes over time within systems of care and their associations with service experiences among youth and their families. Participants were 4,512 youth and their families enrolled in the national evaluation of the Children’s Mental Health Initiative (CMHI). Results suggest that implementation of CLC at the system level improves over time in funded systems of care. Further, variation exists in specific system-level components of CLC. In addition, the changes in CLC at the system level are related to family/caregiver participation in treatment. Implications for supporting positive changes in CLC among systems of care communities, and specific strategies for community psychologists, are discussed.  相似文献

In this article, we test the utility of Agnew's general strain theory to explain suicidal behaviors among American Indian youth. Data from 721 American Indian adolescents from the Midwest and Canada were collected in partnership with participating reservations/reserves and a research team. We investigate the effects of strains/stressors on suicide, including tests of mediating effects of negative emotions on relationships between stressors and suicidality. We found that several strains/stressors were related to suicidality, including coercive parenting, caretaker rejection, negative school attitudes, and perceived discrimination. We also found that depressive symptoms and anger mediated the effects of several key predictors of suicidality. We discuss the theoretical and policy implications of our work for the general strain theory and for American Indian suicide in general.  相似文献

We examine the effect of self-control and opportunity on adolescent substance use. When theorizing about the role of opportunity, we believe the “sanction potential” of a given situation should be considered. Our results suggest the effect of self-control on substance use does not depend on the availability of substances in the home (high sanction potential), but friends’ substance use (low sanction potential) conditions the effect of self-control on adolescents’ smoking, drinking, and marijuana use. Therefore, adolescents with low self-control are more likely to use substances only when they are presented with attractive opportunities that are unlikely to lead to sanctions.  相似文献

Through fieldwork and interviews, this research addresses internal and external social control of drug and alcohol use in “Mell's Belles,” a strip club in a working-class northeastern city. I describe a variety of internal social control techniques used to regulate alcohol and illicit drugs, and then note the impact of external social control on the strip club, including police raids and general surveillance. Strip clubs have an unpredictable, laissez faire approach to rule enforcement, enforcing rules only when necessary. External social control uses legal power to infiltrate Mell's Belles over petty ordinance breaches, and ultimately, drugs. As an underclass population engaged in deviant work, strippers and patrons are unequipped to contend with surveillance regimes.  相似文献
