The rise in suicide by African Americans in the United States is directly attributable to the dramatic, nearly three-fold increase in suicide rates of African American males. Gibbs (1997) hypothesized high social support, religiosity, and southern residence are protective factors against suicidality for Black people. This hypothesis was tested among 5,125 participants from the National Comorbidity Survey; 299 were African American males. In this study we hypothesized that there would be significantly lower suicidality in the South, and social support and religiosity would mediate this relationship. Our results indicate that Southern region is indeed a significant predictor of suicidal symptoms in African American men, such that suicidal symptoms were lower in the South, but religiosity and social support did not account for this effect. Other potential mediators were also examined. 相似文献

Deception research has focused on identifying peripheral nervous system markers while ignoring cognitive mechanisms underlying those markers. Cognitive theorists argue that the process of deception may involve such constructs as attentional capture, working memory load, or perceived incongruity with memory, while psychophysiologists argue for stimulus salience, arousal, and emotion. Three studies were conducted to assess reaction time (RT) in relation to deception, response congruity, and preparedness to deceive. Similar to a semantic verification task, participants evaluated sentences that were either true or false, and then made truthful or deceptive evaluations of the sentence's base truth-value. Findings indicate that deceptive responses have a longer RT than truthful responses, and that this relationship remains constant across response type and preparedness to deceive. The authors use these findings in preliminary support of a comprehensive cognitive model of deception. 相似文献

In this article, we explore whether structural characteristics of the phonological lexicon affect serial recall in typically developing and dyslexic children. Recent work has emphasized the importance of long-term phonological representations in supporting short-term memory performance. This occurs via redintegration (reconstruction) processes, which show significant neighborhood density effects in adults. We assessed whether serial recall in children was affected by neighborhood density in word and nonword tasks. Furthermore, we compared dyslexic children with typically developing children of the same age or reading level. Dyslexic children are held to have impaired phonological representations of lexical items. These impaired representations may impair or prevent the use of long-term phonological representations to redintegrate short-term memory traces. We report significant rime neighborhood density effects for serial recall of both words and nonwords, for both dyslexic and typically developing children. 相似文献

The relative importance of an internal sense of direction based on inertial cues and landmark piloting for small-scale navigation by White King pigeons (Columba livia) was investigated in an arena search task. Two groups of pigeons differed in whether they had access to visual cues outside the arena. In Experiment 1, pigeons were given experience with 2 different entrances and all pigeons transferred accurate searching to novel entrances. Explicit disorientation before entering did not affect accuracy. In Experiments 2-4, landmarks and inertial cues were put in conflict or tested 1 at a time. Pigeons tended to follow the landmarks in a conflict situation but could use an internal sense of direction to search when landmarks were unavailable. 相似文献

This study sought to identify if differences existed in risk comprehension and risk format understanding between genetic counseling
patients of Hispanic and Caucasian ethnicity. A total of 107 questionnaires were collected, 56 from Hispanic patients, and
51 from Caucasian controls. Of the total population 41.1% (44/107) could not demonstrate sufficient risk understanding, which
was 71.4% (40/56) of Hispanics and 7.8% (4/51) of Caucasians. Fractions were the best-understood format for all participants.
However, both Hispanics and Caucasians had difficulties with the percentage risk format. Discrepancies were also noted in
qualitative word format understanding. Awareness of differences in risk comprehension may affect the selection of counseling
techniques and strategies utilized by genetic counselors when educating patients about risk related information. 相似文献

The present study explored how European American women in midlife transition think about their changing bodies and related
sociocultural discourses. The work was informed by theory that illuminates a process in which middle-aged individuals critically
evaluate the meaning structures used to make sense of the world and self and transform these schemes for personal relevance.
In-depth interviews were conducted with 20 women transitioning into their middle-aged years. Data were analyzed using constant
comparison processes. Analyses revealed two major ideological adjustments in participants' thinking, including (a) the shift
from an emphasis upon external to internal aspects of the self and (b) the questioning of dominant social discourses about
the female body. Although these ideological shifts seemingly contributed to participants' acceptance of their bodies at midlife,
participants also expressed ambivalence about their appearances and related social discourses. 相似文献

The objective of this study was to determine the role of health beliefs in genetic amniocentesis acceptance in a diverse racial-ethnic population. Participants completed a previously-validated questionnaire consisting of three sections: (1) demographics, (2) amniocentesis knowledge, and (3) health beliefs, which assessed perceived susceptibility, seriousness of potential impact, benefits of testing, and barriers to testing. The results showed that Hispanic women were less likely to accept amniocentesis (51.5% vs. Caucasian 82.8%, African American 82.9%, Asian 82.8%). Education level was the only demographic factor higher among acceptors. Women who accepted amniocentesis had higher perceived seriousness, susceptibility, and benefits HBM scores and higher knowledge scores than women who declined. HBM scores and knowledge predicted the amniocentesis decision correctly 91.5% of the time. Individual health beliefs and knowledge play a greater role in genetic amniocentesis acceptance than do demographic factors such as race-ethnicity. 相似文献

Little is known about researchers' understanding of confidence intervals (CIs) and standard error (SE) bars. Authors of journal articles in psychology, behavioral neuroscience, and medicine were invited to visit a Web site where they adjusted a figure until they judged 2 means, with error bars, to be just statistically significantly different (p < .05). Results from 473 respondents suggest that many leading researchers have severe misconceptions about how error bars relate to statistical significance, do not adequately distinguish CIs and SE bars, and do not appreciate the importance of whether the 2 means are independent or come from a repeated measures design. Better guidelines for researchers and less ambiguous graphical conventions are needed before the advantages of CIs for research communication can be realized. 相似文献

Life history theory provided a framework for examining the relations among child sexual abuse (CSA), childhood adversity, and patterns of reproductive development and behavior. A community survey that assessed CSA, life history variables (e.g., age of menarche), and social and family background was administered to 623 women (mean age=26.9 years). Independent of social and family background, CSA was associated with earlier age of (a) menarche, (b) first sexual relationship, (c) desire to have children, (d) first childbirth, and (e) lower self-evaluated physical attractiveness. Cluster analyses revealed different patterns of experiential correlates of reproductive development within the group of abused women, suggesting CSA may operate in combination with other childhood circumstances to modify the timing and pattern of individual maturation. 相似文献

This study examined differences between socially anxious and nonanxious individuals' ability to use effective communication skills and social skills in the context of romantic relationships. Socially anxious (n = 13) and nonanxious (n = 14) individuals and their romantic partners were videotaped while participating in 10-minute neutral, negative, and pleasant conversations. Regardless of the type of conversation in which they were involved, socially anxious individuals demonstrated impairment in 10 of the 11 social skill variables assessed. In negative conversations, socially anxious individuals displayed more "very negative" behaviors than nonanxious individuals, and across all conversations they displayed fewer "positive" behaviors than nonanxious individuals. Partners of socially anxious and nonanxious individuals did not differ in their communication quality. The results suggest that social anxiety is associated with deficits in relationship maintenance behavior and call for the completion of a larger study examining the interpersonal consequences of social anxiety. 相似文献
