It is predicted that the rapid acquisition of new genetic knowledge and related applications during the next decade will have significant implications for virtually all members of society. Currently, most people get exposed to information about genes and genetics only through stories publicized in the media. We sought to understand how individuals in the general population used and understood the concepts of “genetics” and “genes.” During in-depth one-on-one telephone interviews with adults in the United States, we asked questions exploring their basic understanding of these terms, as well as their belief as to the location of genes in the human body. A wide range of responses was received. Despite conversational familiarity with genetic terminology, many noted frustration or were hesitant when trying to answer these questions. In addition, some responses reflected a lack of understanding about basic genetic science that may have significant implications for broader public education measures in genetic literacy, genetic counseling, public health practices, and even routine health care.  相似文献

Although linguistic traditions of the last century assumed that there is no link between sound and meaning (i.e., arbitrariness), recent research has established a nonarbitrary relation between sound and meaning (i.e., sound symbolism). For example, some sounds (e.g., /u/ as in took) suggest bigness whereas others (e.g., /i/ as in tiny) suggest smallness. We tested whether sound symbolism only marks contrasts (e.g., small versus big things) or whether it marks object properties in a graded manner (e.g., small, medium, and large things). In two experiments, participants viewed novel objects (i.e., greebles) of varying size and chose the most appropriate name for each object from a list of visually or auditorily presented nonwords that varied incrementally in the number of "large" and "small" phonemes. For instance, "wodolo" contains all large-sounding phonemes, whereas "kitete" contains all small-sounding phonemes. Participants' choices revealed a graded relationship between sound and size: The size of the object linearly predicted the number of large-sounding phonemes in its preferred name. That is, small, medium, and large objects elicited names with increasing numbers of large-sounding phonemes. The results are discussed in relation to cross-modal processing, gesture, and vocal pitch.  相似文献

Self-rated general health has been used widely in health surveys as a single-item measurement of health-rated quality of life. Heterogeneity in self-evaluation of health has been well documented, yet the causes of this heterogeneity are poorly understood. This study evaluated the moderating effects of age, aging, gender, race, education and income on the relationship between physical functioning and self-rated general health using social comparison theory as a guiding framework. A longitudinal mixed-effects regression model was used to analyze a cohort enrolled into the Health and Retirement Study in 1993 that was interviewed at baseline and during four subsequent waves. The results revealed that the association between physical functioning and self-rated general health is weaker among subgroups that tend to have lower health status; i.e., older individuals, non-Caucasians and less educated individuals. These findings suggest the usefulness of social comparison theory in explaining self-rated general health and provide the basis for future research.  相似文献

Theories of attentional control are divided over whether the capture of spatial attention depends primarily on stimulus salience or is contingent on attentional control settings induced by task demands. The authors addressed this issue using the N2-posterior- contralateral (N2pc) effect, a component of the event-related brain potential thought to reflect attentional allocation. They presented a cue display followed by a target display of 4 letters. Each display contained a green item and a red item. Some participants responded to the red letter and others to the green letter. Converging lines of evidence indicated that attention was captured by the cues with the same color as the target. First, these target-color cues produced a cuing validity effect on behavioral measures. Second, distractors appearing in the cued location produced larger compatibility effects. Third, the target-color cue produced a robust N2pc effect, similar in magnitude to the N2pc effect to the target itself. Furthermore, the target-color cue elicited a similar N2pc effect regardless of whether it competed with a simultaneous abrupt onset. The findings provide converging evidence for attentional capture contingent on top-down control settings.  相似文献

This study examined potential differences between the inattentive and combined ADHD subtypes using laboratory tasks assessing behavioral inhibitory processes. Seventy-five children completed two tasks of behavioral inhibition believed to isolate different processes: the cued reaction time task (CRT), a basic inhibition task, and the go/no-go task (GNG), a complex inhibition task that incorporates motivational contingencies. Three groups of participants were identified, including ADHD/Inattentive (n = 17), ADHD/Combined (n = 37), and comparison (n = 21). Results indicated that rather than showing behavioral inhibition deficits, the ADHD/I children appeared overly inhibited, as evidenced by slower reaction times across the two tasks and significantly higher errors of omission in the GNG task. Additionally, the ADHD/I children did not demonstrate cue dependency effects on the CRT task, suggesting that they were failing to incorporate relevant information before making a response. The sluggish and inhibited performance of the ADHD/I group challenges the idea that it is a subtype of ADHD.  相似文献

This paper describes and contrasts three contemporary social psychological theories that focus on why people join and identify with groups: the sociometer model, terror management theory, and uncertainty–identity theory. The sociometer model argues that people have a need to be socially included, and that self‐esteem is a meter of successful inclusion and group belonging. Terror management theory argues that people are motivated to reduce fear of the inevitability of their own death, and that the consensual belief–confirmation provided by groups drives people to belong. Uncertainty–identity theory argues that people have a basic need to reduce uncertainty about themselves, their attributes, and their place in the world, and that cognitive processes associated with group identification reduce such uncertainty. We critically contrast these three accounts to conclude that all three motivational processes may play a role, but that self‐uncertainty may have the benefit of wide generality to all groups and group contexts and of detailed specification of cognitive processes.  相似文献

This article describes a study that examined the relationship between multiple Axis I mental health diagnoses and treatment outcomes for female offenders in prison substance abuse treatment programs. Preliminary findings of the effectiveness of therapeutic community (TC) treatment, modified for female offenders, relative to a control cognitive behavioral treatment condition, are presented. The hypothesis--that participants who fit into multiple diagnostic categories have more dysfunctional symptoms and behaviors at baseline--was confirmed; however, a hypothesized relationship between the number of Axis I diagnoses and 6 month treatment outcomes across five domains (mental health, trauma exposure, substance use, HIV needle risk behaviors, and HIV sexual risk) was not supported. Across all Axis I mental health groups, TC treatment was significantly more effective than the control condition overall, as well as on measures of mental health symptoms and HIV sexual risk. These findings suggest that this TC treatment program, as modified, is an effective model for women with varied diagnoses and diagnostic complexities.  相似文献

Constitutivist accounts of self-knowledge argue that a noncontingent, conceptual relation holds between our first-order mental states and our introspective awareness of them. I explicate a constitutivist account of our knowledge of our own beliefs and defend it against criticisms recently raised by Christopher Peacocke. According to Peacocke, constitutivism says that our second-order introspective beliefs are groundless. I show that Peacocke’s arguments apply to reliabilism not to constitutivism per se, and that by adopting a functionalist account of direct accessibility a constitutivist can avoid reliabilism. I then argue that the resulting view is preferable to Peacocke’s own account of self-knowledge.  相似文献

Two experiments explored age differences in response to reminders of death. Terror management research has shown that death reminders lead to increased adherence to and defense of one's cultural worldview. In Study 1, the effect of mortality salience (MS) on evaluations of moral transgressions made by younger and older adults was compared. Whereas younger adults showed the typical pattern of harsher judgments in response to MS, older adults did not. Study 2 compared younger and older adults' responses to both the typical MS induction and a more subtle death reminder. Whereas younger adults responded to both MS inductions with harsher evaluations, older adults made significantly less harsh evaluations after the subtle MS induction. Explanations for this developmental shift in responses to reminders of death are discussed.  相似文献
