ABSTRACT

A number of investigators have argued that emotion plays an important role in free-choice learning in settings such as museums, science centers, zoos, and aquariums, particularly given the relationship between emotion and cognition. Despite considerable research on the cognitive aspects of visits, empirical studies on emotion in such settings are virtually non-existent. This study investigated the role that emotion plays in facilitating and enhancing learning at a science center. Three major research questions were addressed: (a) Can emotion be measured using Russell's Affect Grid in a non-laboratory setting such as an interactive science center? (b) If so, do different types of science center experiences create measurably different levels of emotional arousal and/or valence in visitors? and (c) If so, was there evidence that elevated arousal and/or valence enhanced or retarded visitors' long-term cognitive science learning? The study provided evidence that emotion could be measured using a modified Affect Grid technique and that a particular traveling exhibition generated arousal levels above baseline levels as determined by a control group. Findings suggest a relationship between emotional arousal and positive changes in visitor long-term cognition, attitudes, and behaviors.  相似文献

Sixty-three frail, elderly patients seen in a university-based outpatient geriatric assessment clinic were divided into three dementia diagnosis categories (Alzheimer’s disease, “other” dementias, cognitively intact) to investigate the use of color cues as memory aids. Recognition time was measured for three cues: (1) same color/different form; (2) same form/different color; and (3) different color/different form. Log transformed response times were longer for form cues (same color/different form) compared to color cues (different color/same form, p =.001; different color/different form, p <.001). No differences in log transformed response time were noted among dementia categories for each test condition. Color cues make a significant difference in short-term memory recall ability compared to form cues. Vivid color-coding the environment of a frail, elderly population may enhance short-term memory and improve functional ability. This may prove to be especially useful in long-term care settings, which provide services to a variety of people with differing cognitive abilities.  相似文献

Discussion of the worldwide corporate development of biotechnologies is sometimes diverted through the introduction of images of heroic medical intervention, exemplified by the statement, “I would do anything to save my daughter.” Such heroic images seem to justify virtually any deployment of resources and nearly any health or environmental risk. But it is instructive for future public discussions to examine the use of such images, and to note that those advocating a prominent role for biotechnologies in an expanding global economy welcome such diversionary patterns. Our responsibility to do our own thinking is beset by conditions that may lead us astray. In a time burdened by profound worry—crushing inequalities among the world's peoples, an ecological crisis, and threat of nuclear war—it is tempting to avert our eyes when we are faced with grave new dangers. Moreover, in our increasingly visual culture, images have come to function as a facsimile of and substitute for real thinking. If we are to have significant discussions about the potential of biotechnology, we must not only be wary of promises of economic growth but must also be mindful of sources of diversion and the appeals of image-thinking. We should strive to become more critical of our own ways of thinking, thus opening the discussion to a fuller consideration of what needs to be saved.  相似文献

Because television has the potential to shape cultural beliefs about both sexual norms and appropriate workplace behavior, it seems important to examine TV’s portrayal of “sexual etiquette” in the workplace. In a content analysis of two episodes of every primetime comedy aired on all broadcast and cable networks during fall 2000, we coded every sexual remark and behavior made in a workplace scene. Across all networks, 85 percent of programs and one in four workplace interactions contained some type of sexual content. Overall, a viewer is likely to hear eleven sexual remarks and see two to three sexual behaviors in a workplace setting per hour; this jumps to twenty-three remarks and nine behaviors on cable networks. Sexual remarks were mostly explicit, made in an office setting, by White men, and were rarely (1.4%) about sexual harassment or discrimination. Although sexual content in the workplace was generally less common on broadcast than cable networks, a broadcast network (Fox) actually had the highest overall rate, with sexual content in 38 percent of workplace scenes. Given that research suggests that TV teaches youth about sexuality and cultivates sexual attitudes and beliefs consistent with televised portrayals, it is alarming that youth may learn from television that sex in the workplace is not only commonplace, but also to be tolerated and enjoyed.  相似文献

The Transcultural Integrative Ethical Decision‐Making Model in counseling addresses the need for including cultural factors in the process of ethical dilemma resolution. This transcultural model incorporates state‐of‐the‐art concepts from multicultural theory into an ethical decision‐making model that is adapted primarily from the Integrative Model developed by V. M. Tarvydas (1998). When appropriate, this transcultural model includes aspects of other ethical resolution models, such as R. R. Cottone's (2001) Social Constructivist Model and A. H. Davis's (1997) Collaborative Model. The proposed model is presented in a step‐by‐step, linear format that can be used by counselors facing ethical dilemmas in a variety of settings and with different cultural groups.  相似文献

Three experiments investigated cross-modal links between touch, audition, and vision in the control of covert exogenous orienting. In the first two experiments, participants made speeded discrimination responses (continuous vs. pulsed) for tactile targets presented randomly to the index finger of either hand. Targets were preceded at a variable stimulus onset asynchrony (150,200, or 300 msec) by a spatially uninformative cue that was either auditory (Experiment 1) or visual (Experiment 2) on the same or opposite side as the tactile target. Tactile discriminations were more rapid and accurate when cue and target occurred on the same side, revealing cross-modal covert orienting. In Experiment 3, spatially uninformative tactile cues were presented prior to randomly intermingled auditory and visual targets requiring an elevation discrimination response (up vs. down). Responses were significantly faster for targets in both modalities when presented ipsilateral to the tactile cue. These findings demonstrate that the peripheral presentation of spatially uninforrnative auditory and visual cues produces cross-modal orienting that affects touch, and that tactile cues can also produce cross-modal covert orienting that affects audition and vision.  相似文献

The ultrasonic motion detector can measure activity in free-ranging Ss; it may be useful in studies of arousal. This device records counts of activity per unit of time. Sixty Ss were run in three experiments to evaluate the convenience and usefulness of the technique.  相似文献

This study examines the extent to which perceptions of partner violence are influenced by aggressor gender and masculinity/femininity, and victim gender. Participants evaluated a case scenario depicting domestic assault. Results found charges were significantly higher and sentences significantly longer when the victim was female. Masculine aggressors were more likely to be perceived as having threatened bodily injury and as having initiated the assault compared to feminine aggressors. Masculine aggressors in heterosexual relationships were more likely to be identified as having initiated an assault compared to feminine aggressors in heterosexual relationships or individuals in same-sex relationships.  相似文献

Objective: Examine psychosocial mediators of the effects of high vs. low-dose resistance training (RT) maintenance interventions among older (ages 50–69), overweight and pre-diabetic adults.

Design: Participants (N = 123) completed a three-month supervised RT initiation phase and were subsequently randomised (time 1) to high or low-dose six-month unsupervised RT maintenance interventions (time 2), followed by a six-month no-contact phase (time 3).

Main Outcome Measures: Online measures of putative mediators and RT behaviour.

Results: RT intervention condition (high vs. low dose) had significant effects on change from time 1 to time 2 in behavioural expectation, self-regulation and perceived satisfaction (f2 = .04–.08), but not outcome expectancies, RT strategies or behavioural intentions (f2 ≤ .02). Change in each of the putative mediators, except for outcome expectancies (f2 ≤ .02), had significant effects on RT behaviour at times 2 (f2 = .12–.27) and 3 (f2 = .23–.40). In a multiple mediation model, behavioural expectation (f2 = .11) and self-regulation (f2 = .06) mediated the effects of RT intervention condition on time 2 RT behaviour, whereas perceived satisfaction did not (f2 = .01). Self-regulation was a significant mediator of intervention effects on time 3 RT behaviour (f2 = .11), but behavioural expectation and perceived satisfaction were not (f2 = .04).

Conclusions: Findings suggest that behavioural expectation and self-regulation are appropriate targets for RT maintenance interventions among at-risk older adults.  相似文献
