Producing content-related gestures has been found to impact students’ learning, whether such gestures are spontaneously generated by the learner in the course of problem-solving, or participants are instructed to pose based on experimenter instructions during problem-solving and word learning. Few studies, however, have investigated the effect of (a) performing instructed gestures while learning concepts or (b) producing gestures without there being an implied connection between the gestures and the concepts being learned. The two studies reported here investigate the impact of instructed hand movements on students’ subsequent understanding of a concept. Students were asked to watch an instructional video—focused on the concept of statistical model—three times. Two experimental groups were given a secondary task to perform while watching the video, which involved moving their hands to mimic the placement and orientation of red rectangular bars overlaid on the video. Students were told that the focus of the study was multitasking, and that the instructed hand movements were unrelated to the material being learned. In the content-match group the placement of the hands reinforced the concept being explained, and in the content-mismatch group it did not. A control group was not asked to perform a secondary task. In both studies, findings indicate that students in the content-match group performed better on the posttest, and showed less variation in performance, than did students in the content-mismatch group, with control students falling in between. Instructed hand movement—even when presented as an unrelated, secondary task—can affect students’ learning of a complex concept. 相似文献

Television (TV) is reemerging as a focal point for common experiences and community formation through the use of various digital technologies while viewing. A prominent example of this is second screening, or the use of various technologies to share reactions to and attitudes and opinions about what we see and hear while watching TV with other (virtual) viewers. We contend that second screening requires communication scholars to rethink the nature of the TV entertainment experience, as the practice increasingly blurs lines between interpersonal and mass communication processes. In this article, we introduce a conceptual model designed to identify key issues to be considered and addressed by those seeking to better understand entertainment experiences during socially shared TV viewing. 相似文献

Previous suicide attempts are a leading risk factor for completed suicide. To identify specific characteristics of those at high risk for attempts, we investigated associations with socioeconomic status (SES). Data from the 2013 Korean Community Health Survey (KCHS) included adults who reported suicidal ideation (N = 220,245). Attempts in the past 12 months were assessed. Associations of demographic, socioeconomic, and suicide‐related behavioral factors were analyzed using multiple logistic regression. Among those with suicidal ideation, 862 (3.9%) had attempted suicide. After stratification by age and gender, results showed that low education and unemployed young adult men and women had significantly higher rates of attempts. The lowest income level was associated with significantly higher rates of attempts in only young adult women. Among those with the lowest and highest income, the association between ideation and attempts was attenuated, whereas it was enhanced among other income groups. 相似文献

顾名思义,财神崇拜,自然是对财富的祈求。社会在不断地发展,人类的物质生活,本来就应该越来越富足,人们对它的追求与祈愿,当也无可厚非。但我们却发现,同样以物质利益的追求为指向,我国本土宗教道教的财神崇拜,与西方传入的拜金主义,其实却存在着本质上的巨大差异。 相似文献

Overall social network size, often the sum of common lifetime relationships, including children, family, and friends, has been linked to cognitive impairment and Alzheimer’s Disease. However, little research has examined the association between network size composition and cognitive function in middle-aged and older adults in the context of race/ethnicity. We investigated the associations between the number of close children, family, and friends independently with executive function (EF) and memory across a subsample of non-Hispanic Black, Hispanic, and non-Hispanic White participants who completed the Health and Retirement Study Harmonized Cognitive Assessment Protocol (N = 2,395). We found that network size composition was more closely linked to EF than memory and that these associations varied by race/ethnicity. Specifically, the strongest associations existed between EF and quadratic estimates of the number of close children of non-Hispanic Black participants, and number of close family members for Hispanic participants. Among Black participants, a curvilinear relationship indicated that two close children were associated with greater EF, while a smaller or larger number of close children were associated with lower EF. On the other hand, among Hispanic participants, higher EF was associated with fewer (0–1) and greater (4-5+) numbers of family member contacts. Overall, these results indicate that examining children, family, and friends independently may be more useful than the common practice of aggregation of overall network size, especially in the context of race/ethnicity. 相似文献

We determined risk factors that discriminate between suicide attempt (SA) adolescents and suicidal ideation only (SI only) adolescents using data from the 2010 Korea Youth Risk Behavior Web‐based Survey (12–19 years; N = 73,238). In males, heavy alcohol use, drug use, and high perceived sadness/hopelessness showed significant effects on the presence of SA versus the presence of SI only. In females, along with these variables, low academic achievement, poor perceived health status, high perceived stress, and unhealthy coping strategy were also significantly related to the presence of SA versus SI only. Therefore, clinical interventions targeting adolescents' psychological distress are warranted to prevent suicide. 相似文献

This research applied the Trans-Theoretical Model and the Construal Level Theory to framing messages for blood donation. People can be at different degrees of readiness for blood donation and are, therefore, dispersed into discrete stages of change. These stages of change correspond to varying psychological distances that define the extent to which a person's thinking on the suggested behavior is abstract (high construal level) or concrete (low construal level). Differences in psychological distance thus affect whether individuals focus on how easy it is to donate blood (feasibility) or on why it is important to donate blood (desirability) in the ad message. This research conducted two studies using a 2 (types of message: feasibility vs. desirability—manipulated) × 3 (stages of change: pre-contemplation vs. contemplation/preparation vs. action/maintenance—measured) between-subject, randomly assigned factorial design experiment. The results of both studies showed that for individuals in the pre-contemplation stage, desirability, rather than feasibility, messages were more likely to produce favorable attitudes toward the ad, its sponsoring organization, and blood donation behavior itself, whereas the opposite was true for those in the action/maintenance stage. Those differences were weakened or not observed for those in the contemplation/preparation stage. These patterns of interaction were not replicated for behavioral intention. Collectively, these findings suggest that tailoring a message according to the intended audience's stage of change should promote positive attitudes for blood donation. Meanwhile, future research is needed to bridge the attitude-behavior gap when it comes to blood donation. 相似文献

There is relatively limited research on psychopathy in non-Caucasian ethnic groups and even less on the utility of the Psychopathy Checklist-Revised (PCL-R) that focuses on PCL-R facet and item scores in predicting violent recidivism. In this study, we assessed the utility of the PCL-R in prospectively predicting violent versus nonviolent recidivism during an 11-year follow-up window. A high-risk sample of 451 incarcerated Korean male offenders was assessed on the PCL-R at baseline. A total of 445 were reconvicted after release (353 violent and 92 nonviolent recidivists). Psychopathy facet scores were higher in violent compared to nonviolent recidivists. Facet 2 (affective) showed the strongest effect size (Cohen's d = 0.53; Percentage change in odds = 22.6%) in predicting violent recidivism. Analyses of the four items constituting the affective facet indicated that callous/lack of empathy (Percentage change in odds = 134.4%) and failure to accept responsibility (Percentage change in odds = 94.5%) were the strongest predictors of violent recidivism. Findings are to our knowledge the first to document the utility of the PCL-R in distinguishing violent from nonviolent recidivism and highlight the role of affective impairment (particularly lack of empathy) in violent recidivism. 相似文献
