The effect of background music on alcohol consumption has been widely researched in the literature, but few studies have tested the effect of sound level on drinking behavior. An experiment was carried out in two bars to test patrons' response to music's loudness. Using random assignment, patrons were exposed to a sound level which was higher than that usually employed in the bars in which the study took place. Analysis showed that a higher sound level than usual was associated with consuming more drinks. An "arousal" hypothesis is used to explain the findings.  相似文献

Background music is a part of our everyday activities. Considerable evidence suggests that listening to music while performing cognitive tasks may negatively influence performance. However, other studies have shown that it can benefit memory when the music played during the encoding of information is also provided during the retrieval of that information, in the so-called context dependent memory effect. Since controversial results may be attributed to the nature of the material to be memorized, the aim of the present study is to compare the potential effect of consistent background music on the immediate and long-term recall of verbal and visuospatial information. Experiment 1 showed that instrumental background music does not benefit nor decrease recall of a list of unrelated words, both at the immediate and the 48-hours-delayed tests. By contrast, Experiment 2 revealed that the same background music can impair immediate and therefore long-term memory for visuospatial information. Results are interpreted in terms of competition for neurocognitive resources, with tasks mostly relying on the same brain hemisphere competing for a limited set of resources. Hence, background music might impair visuospatial memory to a greater extent than verbal memory, in the context of limited capacity cognitive system. In conclusion, the nature of the material to be learnt must be considered to fully understand the effect of background music on memory.  相似文献

The effect of the emotional quality of study-phase background music on subsequent recall for happy and sad facial expressions was investigated. Undergraduates (N = 48) viewed a series of line drawings depicting a happy or sad child in a variety of environments that were each accompanied by happy or sad music. Although memory for faces was very accurate, emotionally incongruent background music biased subsequent memory for facial expressions, increasing the likelihood that happy faces were recalled as sad when sad music was previously heard, and that sad faces were recalled as happy when happy music was previously heard. Overall, the results indicated that when recalling a scene, the emotional tone is set by an integration of stimulus features from several modalities.  相似文献

A comparison was made of the intelligence and achievement of three groups of disadvantaged Negro kindergarten children: 27 who attended a summer Headstart program, 56 who attended a year-long Prekindergarten program, and 44 who had no preschool experience. No differences were found in test scores among the groups. When the socioeconomic background of the children was investigated, it was found that although the children were correctly classified as lower class, there were differecees among them in terms of socioeconomic status, and these differences were related to their test scores. The results suggest that the common practice of grouping all disadvantaged children in one category (lower class) may mask differences that may have an important effect on the children's ability to benefit from compensatory education programs. This may make it difficult to determine whether compensatory education has been effective.  相似文献

Conventional Bayesian analysis for proportions is not appropriate for proportions with a background effect, for example, for the proportion of correct responses in a sensory difference test using a forced‐choice method with a guessing probability. The main difficulty is that it is not reasonable to assume that a proportion with a background effect has a beta prior distribution. A generalized posterior distribution for proportions is derived in this paper. It includes the standard beta posterior distribution for a proportion without background effect as a special case. Bayesian inference and Bayesian sample size determination for proportions based on the generalized posterior distribution are discussed.  相似文献

Redundancy analysis an alternative for canonical correlation analysis   总被引:12,自引:0,他引:12  
A component method is presented maximizing Stewart and Love's redundancy index. Relationships with multiple correlation and principal component analysis are pointed out and a rotational procedure for obtaining bi-orthogonal variates is given. An elaborate example comparing canonical correlation analysis and redundancy analysis on artificial data is presented.A Fortran IV program for the method of redundancy analysis described in this paper can be obtained from the author upon request.  相似文献

Preference for fixed-interval schedules: an alternative model   总被引:10,自引:10,他引:0       下载免费PDF全文
Pigeons were trained under concurrent chain schedules in which the initial links were equal aperiodic schedules and the terminal links were fixed-interval schedules. Choice proportions in the initial links were measured in 26 experimental conditions. The data showed the inadequacy of previous models of concurrent chain performance. A new model was suggested in which choice is a joint function of terminal-link times, overall reinforcement rates, and terminal-link entries. This model accounted for 94% of the variance in the present data and for substantial percentages of the variance in previously reported data. The model simplifies to matching between response ratios and obtained reinforcement rate ratios for simple concurrent schedule performance.  相似文献

Sixty‐eight 2‐ to 12‐year‐olds and 30 adults were shown colorful displays on a touchscreen monitor and trained to point to the location of a named color. Participants located targets near‐perfectly when presented with four abutting colored patches. When presented with three colored patches on a colored background, toddlers failed to locate targets in the background. Eye tracking demonstrated that the effect was partially mediated by a tendency not to fixate the background. However, the effect was abolished when the targets were named as nouns, whilst the change to nouns had little impact on eye movement patterns. Our results imply a powerful, inbuilt tendency to attend to objects, which may slow the development of color concepts and acquisition of color words.

Can economics, which is based on the notion of individual optimization, really model individuals who have a sense of exteriority? This question, derived both from Marcel Mauss's sociological analysis of the social norm of gift-giving and from Emmanuel Levinas's phenomenological analysis of the idea of 'otherness,' leads to the problem of whether it is possible to model altruism with the tool of optimization. By investigating the ways in which economic theory can address this challenge, and by introducing a postulate of methodological altruism following Levinas's theory of the constitution of subjectivity through otherness, this paper uncovers an alternative foundation for the very notion of optimizing calculation - no longer as a self-centered initiative, but rather as an other-centered response. This makes it possible to clarify the implicit content of usual economic individualism, and to see on the basis of which ethical arguments the economic method of optimization may be upheld. The paper studies the consequences of this renewed foundation of optimization for the organization of a fair and efficient interaction between altruists.  相似文献

An alternative paradigm for diagnosis based on cybernetics, ecology, and systems theory is proposed. This paradigm, termed "ecosystemic epistemology," suggests that diagnosis focus on knowing problematic situations in an ecological and systemic way. Theoretical statements concerning this approach are delineated with specific references to major family therapists. This discussion provides a foundation for an ecosystemic epistemology for diagnosis that addresses the following issues: (a) the meaning of system; (b) the symptom's presence in the system; (c) the therapist's presence in the system; (d) the ecological relationship system that emerges in diagnosis; and (e) the relation between ecosystemic epistemology and the process of diagnosis. In effect, this paper attempts to formally describe the underlying epistemology inherent in the work of therapists who approach diagnosis in an ecological and systemic way.  相似文献

Research on the effects of context and task on learning and memory has included approaches that emphasize processes during learning (e.g., Craik & Tulving, 1975) and approaches that emphasize a match of conditions during learning with conditions during a later test of memory (e.g., Morris, Bransford, & Franks, 1977; Proteau, 1992; Tulving & Thomson, 1973). We investigated the effects of auditory context on learning and retrieval in three experiments on memorized music performance (a form of serial recall). Auditory feedback (presence or absence) was manipulated while pianists learned musical pieces from notation and when they later played the pieces from memory. Auditory feedback during learning significantly improved later recall. However, auditory feedback at test did not significantly affect recall, nor was there an interaction between conditions at learning and test. Auditory feedback in music performance appears to be a contextual factor that affects learning but is relatively independent of retrieval conditions.  相似文献

When designing new Advanced Driver Assistance Systems (ADAS), the existing guidelines like the RESPONSE 3 Code of Practice imply intense testing of the system prior series production. Within the EU-FP7-Project ISi-PADAS a new methodology of risk based design has been established which includes an integrated simulation platform. This integration enables intense testing of new prototypes in an accelerated way and therefore enhances the design process while directly combining the simulation results with a risk matrix.This paper describes the new methodology while focussing on the software framework and the procedure of risk assessment in detail. It shows the general approach as well as the appropriate steps taken for an ADAS prototype developed in the context of ISi-PADAS.  相似文献

The authors, a Lutheran and a Pentecostal, explore similarities and differences between their respective traditions using German Lutheran Pietism as a bridge. Parallels include conversionism, devotion to the Bible, practical holiness, missional activism, and opposition to the shortcomings of the religious status quo. Key divergences between the movements include the role of the sacraments, the place of manifestational gifts, and eschatology. The authors highlight how Pietism can be a useful channel and translator for dialogue.  相似文献

This study examined the effectiveness of the Fitness Game, an intervention created for the restoration of competency to stand trial. Of 28 participants who completed either the experimental or control intervention at Hawai'i State Hospital (HSH), it was found that both groups had significant pretest to posttest improvements on Understanding and Appreciation subsets of the MacArthur Competence Assessment Tool-Criminal Adjudication (MacCAT-CA). However, there was no statistically significant difference between the groups on competency measures, indicating that the Fitness Game was not significantly more effective at restoring competency than non-legal programming. In other words, individuals committed to a psychiatric hospital for care and treatment were as likely to improve as those receiving additional specialized competency restoration treatment.  相似文献

In a paper written by J. C. Falmagne and the author a representation theorem for what was called a bi-semiorder was given. A quite different proof of this theorem is given here based on Scott's linear technique. This new proof is somewhat simpler than the first one and has the advantage to be an application of a general method well known in measurement theory.  相似文献

Although electronic devices may enhance the effectiveness of some behavioral interventions for children with autism spectrum disorders, such devices may also give rise to problem behavior such as repetitious button pressing (i.e., object stereotypy). Results of this study showed that a child with autism spectrum disorder only displayed high levels of object stereotypy on an iPad? when presses generated auditory output. Subsequently, results showed that when the participant used the iPad? without auditory output, his stereotypical behavior decreased and his manding for various items simultaneously increased.  相似文献

In this research, we show that despite a choice set configuration that promotes the compromise effect, consumers do not always prefer the middle alternative but rather choose the extreme option when one of the attributes has higher discriminability than the other. We use findings from the numerical cognition literature to demonstrate why this happens and, more importantly, provide a novel theoretical framework for what we call the “non-compromise extreme effect.” The findings are unique to the compromise effect literature, which has consistently shown the effect to be robust. More importantly, the findings show that a brand can successfully compete with a well-established competitor when it performs better on the low performing attribute, which gives a leeway to managers to take share away from the competitor.  相似文献
