A prominent focus of New Age beliefs and practices has always been health and healing—including the use of holistic healing, power crystals, homeopathy, and complementary and alternative medicine. Given its association with modern science and medicine, genetic testing would seem to run counter to New Age alternative medical practices. On the other hand, the use of at-home genetic health tests and the use of such New Age alternative medical practices could both be motivated by a desire for personalized healthcare. Using data generated from a survey fielded on a probability sample of U.S. adults, we examine associations between individuals’ use of at-home genetic health tests and their use of power crystals and acupuncture or other homeopathic medicine. Logistic regression models find that those who use power crystals or homeopathic medicine have significantly greater odds of having used an at-home genetic health test. We discuss the implications of these findings for our understanding of the direct-to-consumer genetic testing market and the relationship between science, religion, and spirituality more broadly.  相似文献

Here we attempted to clarify the role of dopamine signaling in reward seeking. In Experiment 1, we assessed the effects of the dopamine D(1)/D(2) receptor antagonist flupenthixol (0.5 mg/kg i.p.) on Pavlovian incentive motivation and found that flupenthixol blocked the ability of a conditioned stimulus to enhance both goal approach and instrumental performance (Pavlovian-to-instrumental transfer). In Experiment 2 we assessed the effects of flupenthixol on reward palatability during post-training noncontingent re-exposure to the sucrose reward in either a control 3-h or novel 23-h food-deprived state. Flupenthixol, although effective in blocking the Pavlovian goal approach, was without effect on palatability or the increase in reward palatability induced by the upshift in motivational state. This noncontingent re-exposure provided an opportunity for instrumental incentive learning, the process by which rats encode the value of a reward for use in updating reward-seeking actions. Flupenthixol administered prior to the instrumental incentive learning opportunity did not affect the increase in subsequent off-drug reward-seeking actions induced by that experience. These data suggest that although dopamine signaling is necessary for Pavlovian incentive motivation, it is not necessary for changes in reward experience, or for the instrumental incentive learning process that translates this experience into the incentive value used to drive reward-seeking actions, and provide further evidence that Pavlovian and instrumental incentive learning processes are dissociable.  相似文献

Recent acts of violence have demonstrated the impact of violent ideological groups worldwide. However, the systematic study of these groups is somewhat limited. The Internet is a valuable tool for investigating ideological group behavior because it is easily accessible and commonly used by these groups. This study attempted to extend previous research by examining online message boards to assess processes particular to ideological group membership. A content analysis was conducted on several group process variables using 29 groups with message boards. A Kruskal‐Wallis test with follow‐up pairwise comparisons was used to find that violent ideological groups differed from nonviolent ideological and nonviolent nonideological groups on 7 group process variables and 3 content variables. Implications are discussed.  相似文献

Anecdotes and introspective reports from eminent scientists and artists aside, a systematic test of the putative creativity-enhancing effect of anger is missing. This article fills this void with three experiments examining creativity as a function of anger (vs. sad or a mood-neutral control state). Combining insights from the literatures on creativity and on mood and information processing the authors predicted that anger (vs. sadness and a mood-neutral control state) triggers a less systematic and structured approach to the creativity task, and leads to initially higher levels of creativity (as manifested in original ideation and creative insights). Following work on resource depletion, the authors further predicted that anger more than sadness depletes resources and that, therefore, creative performance should decline over time more for angry than for sad people. Results supported predictions. Implications for creativity, information processing, and resource depletion are discussed.  相似文献

Connectives, such as because, are routinely used by parents when addressing their children, yet we do not know to what extent children are sensitive to their use. Given children's early developing abilities to evaluate testimony and produce arguments containing connectives, it was hypothesized that young children would show an appropriate reaction to the presence of connectives. Three experiments were conducted to test this hypothesis. In each, two informants gave contradicting statements regarding the location of an object and justified their positions by using a similar argument. Only one of the informants used the connective because to link his argument to the statement. In each experiment, the 3-year-olds performed at chance in selecting choices containing the connective because, but the 4- and 5-year-olds performed above chance. Moreover, in Experiments 2 and 3, the 4-year-olds, 5-year-olds, and adults performed significantly better than the 3-year-olds. These findings show that 4-year-olds, 5-year-olds, and adults are sensitive to the presence of connectives. An interpretation of the difference in performance between the 3-year-olds and the 4- and 5-year-olds in terms of metarepresentational skills is suggested.  相似文献

It has been argued that groups with individualistic norms are more creative than groups with collectivistic norms (Goncalo & Staw, 2006). This conclusion, however, may be too unspecific, as individualism–collectivism denotes a multidimensional continuum and may affect people's self-construal and values. This study analyzed to what extent these dimensions differentially impact upon group creativity. After manipulating self-construal and value orientation, 58 triads engaged in a brainstorming task. Groups with collectivistic value orientation generated more ideas than groups with individualistic value orientation. Furthermore, there was an interaction between value orientation and self-construal on originality: ideas were more original when group members combined collectivistic value orientation with individualistic self-construal. Thus, groups should integrate elements of both individualism and collectivism to ensure high creativity.  相似文献

Compared with approach motivation, avoidance motivation has often been related to reduced creativity because it evokes a relatively inflexible processing style. This finding seems inconsistent with the dual pathway to creativity model, which poses that both flexible and persistent processing styles can result in creative output. Reconciling these inconsistencies, the authors hypothesized that avoidance-motivated individuals are not unable to be creative, but they have to compensate for their inflexible processing style by effortful and controlled processing. Results of 5 experiments revealed that when individuals are avoidance motivated, they can be as creative as when they are approach motivated, but only when creativity is functional for goal achievement, motivating them to exert the extra effort (Experiments 1-4). The authors found that approach motivation was associated with cognitive flexibility and avoidance motivation with cognitive persistence (Experiment 1), that creative tasks are perceived to be more difficult by avoidance- than by approach-motivated individuals, and that avoidance-motivated individuals felt more depleted after creative performance (Experiment 2a, 2b, and 3). Finally, creative performance of avoidance-motivated individuals suffered more from a load on working memory (Study 4). The present results suggest that for people focusing on avoiding negative outcomes, creative performance is difficult and depleting, and they only pay these high cognitive costs when creativity helps achieving their goals.  相似文献

This study examined gender differences in student engagement and academic performance in school. Participants included 3420 students (7th, 8th, and 9th graders) from Austria, Canada, China, Cyprus, Estonia, Greece, Malta, Portugal, Romania, South Korea, the United Kingdom, and the United States. The results indicated that, compared to boys, girls reported higher levels of engagement in school and were rated higher by their teachers in academic performance. Student engagement accounted for gender differences in academic performance, but gender did not moderate the associations among student engagement, academic performance, or contextual supports. Analysis of multiple-group structural equation modeling revealed that perceptions of teacher support and parent support, but not peer support, were related indirectly to academic performance through student engagement. This partial mediation model was invariant across gender. The findings from this study enhance the understanding about the contextual and personal factors associated with girls' and boys' academic performance around the world.  相似文献

The purpose of this study was to compare the speed of phonological encoding between adults who stutter (AWS) and adults who do not stutter (ANS). Fifteen male AWS and 15 age- and gender-matched ANS participated in the study. Speech onset latency was obtained for both groups and stuttering frequency was calculated for AWS during three phonological priming tasks: (1) heterogeneous, during which the participants' single-word verbal responses differed phonemically; (2) C-homogeneous, during which the participants' response words shared the initial consonant; and (3) CV-homogeneous, during which the participants' response words shared the initial consonant and vowel. Response words containing the same C and CV patterns in the two homogeneous conditions served as phonological primes for one another, while the response words in the heterogeneous condition did not. During each task, the participants produced a verbal response after being visually presented with a semantically related cue word, with cue-response pairs being learned beforehand. The data showed that AWS had significantly longer speech onset latency when compared to ANS in all priming conditions, priming had a facilitating effect on word retrieval for both groups, and there was no significant change in stuttering frequency across the conditions for AWS. This suggests that phonological encoding may play no role, or only a minor role, in stuttering. EDUCATIONAL OBJECTIVES: The reader will be able to: (1) describe previous research paradigms that have been used to assess phonological encoding in adults and children who stutter; (2) explain performance similarities and differences between adults who do and do not stutter during various phonological priming conditions; (3) compare the present findings to past research that examined the relationship between phonological encoding and stuttering.  相似文献

Stereotypic beliefs about older adults and the aging process have led to endorsement of the myth that 'to be old is to be ill.' This study examined community-dwelling older adults' (N?=?105, age 80+) beliefs about the causes of their chronic illness (ie, heart disease, cancer, diabetes, etc.), and tested the hypothesis that attributing the onset of illness to 'old age' is associated with negative health outcomes. A series of multiple regressions (controlling for chronological age, gender, income, severity of chronic conditions, functional status and health locus of control) demonstrated that 'old age' attributions were associated with more frequent perceived health symptoms, poorer health maintenance behaviours and a greater likelihood of mortality at 2-year follow-up. The probability of death was more than double among participants who strongly endorsed the 'old age' attribution as compared to those who did not (36% vs. 14%). Findings are framed in the context of self-directed stereotypes and implications for potential interventions are considered.  相似文献
