Artist trading cards (ATCs) are miniature works of art that are created within the dimensions of standardized trading cards or playing cards (2.5 inches × 3.5 inches). ATCs can be made with a variety of media—everything from pen and ink to oil paints, collages, mosaics, stamping, and altered photos. Using this compact art format as an expressive arts intervention in the therapeutic environment provides the counselor with most, if not all, of the same therapeutic benefits of larger art media (e.g., expressive release, creativity, artistic communication, symbolic self-expression, self-exploration, etc.). The unique benefit of the ATC format is that ATCs allow for traditional expressive arts interventions to be “better, faster, and cheaper” in many ways.  相似文献

Feedforward control is a process adjusting behaviour in a continuative way. Feedforward takes place when an equilibrium state is disrupted and the system has to automatically retrieve the homeostatic stable state. It also occurs when a perturbation is previewed and must be eliminated in order to achieve a desired goal. According to the most general definition, a feedforward process operates by fixing the future representation of the desired state, the achieving of which stops the process. Then, feedforward works by means of the refinement determined by successive comparisons between the actual and target products. In its applications, a feedforward process is thought to be modulated by the subject’s purpose and the environmental state. Over the years, the feedforward process has assumed different connotations in several contests of cognitive psychology. An overview of the research fields in psychology that significantly progressed with the introduction of a feedforward paradigm is provided by: (a) reviewing models in which the feedforward concept plays a fundamental role in the system control; (b) examining critical experiments related to the interaction of feedforward and feedback processes; (c) evidencing practical applications for some of the presented feedforward-based architectures.  相似文献

The aim of the study was to provide a standardization of self-reported competences and emotional/behavioural problems in Spanish adolescents, using the Achenbach's Youth Self-Report (YSR), and to compare our results to those from other countries. The YSR was completed by 2822 adolescents aged 11-18 years, recruited from secondary schools in two regions of Spain. There were significant differences in Total behaviour problems and in most problem scales in boys and girls, scoring boys higher on externalizing syndromes, whereas girls score higher on internalizing syndromes . Males' mean scores were higher than females' scores for social competence. Age effects also showed significant differences with respect to internalizing problems, thought problems, social problems and depression. Cut-off points based on the 90th and 98th percentile developed from this sample are presented for the competences and the problem scales. To test the overall range of variations across cultures, comparisons were made between broad band and narrow band measures of the YSR in Spanish adolescents and those from other countries. Gender differences in the YSR were similar to those found across different cultures; there is a consistent trend to increase behavioural problems with age; and social competence seem to be a relevant protective factor against behavioural problems.  相似文献

In two experiments, thirsty rats consumed a compound of sucrose and a non-preferred flavor. In Experiment 1, a conditioned preference was observed in the experimental group when animals were tested both thirsty and hungry, but not when they were tested just thirsty. Animals in the control group, which experienced the flavor and the sucrose unpaired, never showed a preference. Experiment 2 replicated the absence of a preference in the experimental group when rats were tested thirsty, but provided evidence that a flavor-taste association had been formed during training. After conditioning, sucrose was paired with LiCl in group Dev whereas it was unpaired in group NonDev. The sucrose devaluation produced a decrease in CS preference in group Dev, and an increment in group NonDev. Taken together, these results show that preference for a non-preferred flavor can be readily observed after pairings with the positive consequences of the US (calories or absence of an expected illness) rather than with a palatable flavor.  相似文献

Our purpose in the following was to investigate the start-up rhetoric employed by U.S. President Barack Obama in his speeches. The initial 5 min from eight of his speeches from May to September of 2009 were selected for their variety of setting, audience, theme, and purpose. It was generally hypothesized that Barack Obama, widely recognized for the excellence of his rhetorical performance, would pursue both constant and variable strategies in his effort to establish contact with his audience. More specifically, it was hypothesized that the make-up of the audience—primarily native or non-native speakers of English—would be a prominent independent variable. A number of temporal and verbal measures were used as dependent variables. Variations were evident in mean length in syllables and duration in seconds of utterances (articulatory phrases), articulation rate in syllables per second of ontime, mean duration of silent pauses in seconds, and frequency of fillers, hesitations, colloquial words and phrases, introductory phrases, and 1st person singular pronominals. Results indicated that formality versus informality of the setting and presence or absence of a teleprompter were more prominent than native versus non-native audiences. Our analyses confirm Obama’s skillfulness in challenging and variable settings and clearly detect orderliness and scientific generalizability in language use. The concept of orality/literacy provides a theoretical background and emphasizes dialogical interaction of audience and speaker.  相似文献

Empirical studies of personality traits in creative writers have demonstrated mixed findings, perhaps due to issues of sampling, measurement, and the reporting of statistical information. The goal of this study is to quantify the personality structure of aspiring creative writers according to a modern hierarchal model of trait personality. A sample of aspiring writers (n = 93) and nonwriters (n = 114) completed the Big Five inventory. Correlations with personality were carried out at three levels: the Big Five traits, the two higher-order factors (stability and plasticity), and the more detailed facet-level. Consistent with past research, creative writers scored higher on trait openness. Extending past work, the hierarchical analysis also revealed novel correlates for the higher-order meta-traits (stability and plasticity) and some of the lower-order facets (aesthetics, ideas, activity, assertiveness, and depression). Individuals with higher scores on agreeableness, stability, and assertiveness were less likely to be aspiring writers. The likelihood of being a writer also decreased with age. Taken together, these findings indicate that aspiring creative writers differ from nonwriters in trait personality, with differences emerging at all levels of the personality hierarchy.  相似文献

This article outlines advances in intuition research and draws attention to several misconceptions, based on conflicting assumptions about the intuition construct and the intuiting process. In particular, it focuses on the distinction between process and outcome, the role of consciousness and affect, the research focus on decision making or problem solving, and the differential use of intuition in technical and creative settings. It calls for a comprehensive intuition model that would refute some of the misconceptions and proposes three types of intuition: intuitive expertise, intuitive creation, and intuitive foresight.  相似文献

This research aims to analyze the relationship between sociocultural values and human food preferences. The latter, as shown in this paper, are greatly influenced by cultural identity. This work stems from a theoretical context that originated in Europe and the United States towards the mid‐twentieth century, within the field of the anthropology of food. A qualitative and quantitative analysis has been performed in the Comunidad Autónoma de Aragón (Spain). Research methods include focus groups, in‐depth interviews, participant observation, and a questionnaire that was handed out to a representative sample of the Aragonese population (816 people over 21 years of age; confidence level of 95.5% and error margin of ±3.5). Regarding the research outcome, a highly significant qualitative and quantitative connection has been found between food selection and cultural identity. In other words, people prefer to consume foods that are symbolically associated with their own culture, in order to reinforce their sense of belonging. Although this study has been carried out in Aragón, it is our belief that the results can be generalized to other areas. The originality and interest of our findings are notable considering that, to date, few works have analyzed the sociocultural factors motivating food behavior. Moreover, these results could be used by public and private organizations to meet objectives such as health promotion and product marketing.  相似文献

We aim to analyze the effects of an 8-month physical activity intervention on cardiorespiratory fitness, body mass index (BMI), and vigilance performance in an adult obese population. We conducted an 8-month physical activity intervention based on dance and rhythmic activities. The weekly frequency was 2 sessions of 1 hr per day. Training sessions were divided into 3 phases: a 10-min warm-up, 40 min of dance and rhythmic activities, and 10 min to cool-down. To assess cardiorespiratory fitness, participants performed a modified version of the 6-min walk test from the Senior Fitness Test battery (Larsson & Mattsson, 2001; Rikli & Jones, 1999). Vigilance performance was measured by means of the psychomotor vigilance task (PVT). Two measurements were performed immediately before and after the intervention. The results revealed that participants improved their cardiorespiratory fitness, BMI, and vigilance performance after the intervention. All in all, findings contribute new empirical evidence to the field that investigates the benefits of physical activity intervention on cognitive processes in obese population.  相似文献

Reasoning about mechanisms is one of the hallmarks of disciplined inquiry in science and engineering, but comparatively little is known about its precursors and development. Children at grades 2 and 5 predicted and explained the motion of simple mechanical systems composed entirely of visible linkages (levers). Students' explanations of device behavior suggested four forms of knowledge: simple recognition of device components, noting of structural relations among components, construction of cause-effect rules derived by observation of regularities in device behavior, and identification of essential system components and interactions among components that accounted for cause–effect rules. Only a few children coordinated multiple essential components to constitute a mechanistic causal scheme. Mechanistic causal schemes, in turn, were associated with successful prediction of the output motion of a system. Device tracing via gesture and talk appeared to support this form of knowledge development, and hence may inform future instructional design.  相似文献
