OBJECTIVE: To test a hypothesis derived from H. Leventhal, D. Meyer, and D. Nerenz's (1980) commonsense model that people possess implicit schemas for specific illnesses. DESIGN: A 2 (illness vs. neutral shopping prime) x 2 (illness-related vs. control word) mixed design with repeated measures on the second factor. Participants primed for the common cold (Experiment 1) and cardiovascular disease (Experiment 2) were compared with participants receiving a neutral shopping prime on a modified Stroop color naming task. MAIN OUTCOME MEASURES: Attentional bias to illness related words was calculated as the difference between response latencies to illness words and neutral words under the prime conditions. RESULTS: In Experiment 1, participants primed with common cold showed a response bias to words related to the common cold but not to words related to cardiovascular disease. Attentional bias among participants primed for common cold was significantly correlated with explicit illness representations assessed by the Revised Illness Perception Questionnaire. Experiment 2 replicated the findings in a different illness domain. CONCLUSION: Illness-specific illness schemas can be activated.  相似文献

This study utilized national panel data gathered in 2008 (T1) and 2010 (T2) to examine associations between Black and White U.S. adults' pornography consumption and homosexuality attitudes (indexed via moral judgments of homosexuality and attitudes toward same‐sex marriage). Pornography consumption at T1 predicted interindividual change in attitudes toward more acceptance of homosexuality at T2 for moral individualists, Whites, and men. Women expressed more positive homosexuality attitudes than men, but their attitudes did not vary with exposure to pornography. Homosexuality attitudes at T1 did not predict interindividual change in the probability of pornography consumption at T2. Results were parallel when moral judgments of homosexuality and attitudes toward same‐sex marriage were analyzed separately or were combined into a composite index.  相似文献

An experiment was designed to determine the degree to which reciprocal aiming movements of the wrist and arm with various accuracy requirements (Fitts' tasks) are enhanced by extended practice. The vast majority of research on motor learning shows performance improvement over practice. However, literature examining the effect of practice on Fitts' task performance is limited and inconclusive. Participants were asked to flex/extend their limb/lever in the horizontal plane at the wrist (arm stabilized) or elbow joint (wrist stabilized) in an attempt to move back and forth between two targets as quickly and accurately as possible. The targets and current position of the limb were projected on the screen in front of the participant. Target width was manipulated with amplitude constant (16°) in order to create indexes of difficulty (ID) of 1.5, 3, 4.5, and 6. Contrary to the earlier reports, after 20 days of practice, we found minimal changes in movement time or the movement time-ID relationships for the arm and wrist over practice. However, the variability in the movement endpoints decreased over practice and wrist movements at ID=6 were characterized by shorter movement times and longer dwell times relative to arm movements with dwell time for the wrist increasing over practice. These data are consistent with the notion that Fitts' tasks provide a stable measure of perceptual-motor capabilities.  相似文献

This study examined the percentage of children who respond positively to a daily report card (DRC) intervention and the extent to which students achieve incremental benefits with each month of intervention in a general education classroom. Participants were 66 children (87% male) with attention-deficit hyperactivity disorder or disruptive behavior problems who were enrolled in a school-based intervention program in rural, low-income school districts in a Midwest state. The DRC was implemented by each child's teacher, who received consultation from a graduate student clinician, school district counselor, or school district social worker. A latent class analysis using growth-mixture modeling identified two classes of response patterns (i.e., significant improvement and significant decline). Results indicated that 72% of the sample had all of their target behaviors classified as improved, 8% had all of their targets classified as declining, and 20% had one target behavior in each class. To examine the monthly incremental benefit of the DRC, individual effect sizes were calculated. Results for the overall sample indicated that most children experience a benefit of large magnitude (.78) within the first month, with continued incremental benefits through Month 4. The differential pattern of effect sizes for the group of improvers and the group of decliners offer data to determine when and if the DRC should be discontinued and an alternative strategy attempted. Evidence-based guidelines for practical implementation of the DRC are discussed.  相似文献

This article reviews the work of the psychiatrist Hugh Mullan, a pioneer of modern group therapy. Heavily influenced by existential philosophy, Hugh Mullan applied notions from that perspective to his innovative and unorthodox approach. Central to this was an early, indeed prescient, advocacy for the use of the therapist's personal subjectivity, striving for mutuality, and non-rational experience in the conduct of psychotherapy. This way of thinking was not in accord with prevailing theories throughout most of his life as a practitioner (1946-1986); Hugh Mullan was not considered a mainstream theorist in his time. However, contemporary relational theorists have begun to give these ideas a great deal of attention, offering validation and support for his original insights. This writer recalls, as well, his experience of Hugh Mullan as a therapist and mentor.  相似文献

The objective of this research was to evaluate the hypothesis that twin relationships are attachments, using data from a nationally representative sample. The results indicated that twin siblings were more likely than nontwin siblings to be attached to their siblings. Moreover, analyses indicated that both attachment theoretical and inclusive fitness perspectives are necessary for explaining these findings. Namely, twins were more likely to be attached than nontwin siblings, as expected from an attachment perspective. But identical twins were more likely than fraternal twins to be attached to one another, as might be expected from an inclusive fitness perspective. Cross-sectional analyses indicated that older people are less likely than younger people to use their sibling as an attachment figure compared to younger people and that married adults are less likely to use their sibling as an attachment figure than nonmarried people.  相似文献

Studies of national identity distinguish between ethnic and civic nations and have sought to identify these alternative conceptions of national identity in public opinion. The standard measurement technique is to assess the normative content of American national identity by asking survey respondents to rate the importance of particular traits for making someone a “true” American. We argue that such measures are problematic, chiefly because of the impact of nonrandom measurement error. We explore the influence of using ranking measures instead of ratings, using a survey experiment conducted on a nationally representative sample of Americans in 2008. The ranking method is superior for distinguishing between ethnic and civic conceptions of nationhood and, therefore, for predicting preferences on issues such as immigration policy. We develop a new statistical method that effectively “converts” ratings into scores that approximate rankings, resulting in the creation of more valid measures of both ethnic and civic national identities.  相似文献
