Two experiments demonstrated the way in which musicians and nonmusicians process realistic music encountered for the first time. A set of tunes whose members were related to each other by a number of specific musical relationships was constructed. In Experiment 1, subjects gave similarity judgments of all pairs of tunes, which were analyzed by the ADDTREE clustering program. Musicians and nonmusicians gave essentially equivalent results: Tunes with different rhythms were rated as being very dissimilar, whereas tunes identical except for being in a major versus a minor mode were rated as being highly similar. In Experiment 2, subjects learned to identify the tunes, and their errors formed a confusion matrix. The matrix was submitted to a clustering analysis. Results from the two experiments corresponded better for the nonmusicians than for the musicians. Musicians presumably exceed nonmusicians in the ability to categorize music in multiple ways, but even nonmusicians extract considerable information from newly heard music.  相似文献

Job insecurity is a widespread workplace stressor that has been extensively investigated using quantitative approaches. With the use of a critical organisational psychology framework, we conducted a meta-synthesis of 20 qualitative studies to investigate the experience of job insecurity among vulnerable employee groups (i.e., women and immigrants). The qualitative meta-synthesis results suggest that there are meaningful differences. Specifically, whereas women were more concerned with and exposed to deteriorating working conditions, men experienced job insecurity as a threat to their identity. Among immigrants, the experience of job insecurity is viewed as largely intersecting with the legal system, impacting their ability to remain in their country and making them feel powerless. Thematic evidence also emerged regarding individual actions that participants use to attain security in contrast to corporate strategies that enhance job insecurity. We contribute to the critical organisational psychology literature by discussing how these results test common academic theories and neoliberal assumptions pervasive within the job insecurity literature: We highlight how organisations manufacture job insecurity, question the existence of harmonious social exchanges, discuss the use of job insecurity as a form of worker control, consider the role of the legal context in aiding worker exploitation and argue for an intersectional view of job insecurity.  相似文献

The advice to musicians and marketers is to focus on what they love: a truism for practitioners is to find 1000 ‘true fans’ and make $100 from each of them (Kelly, 2008. 1000 True fans. The Technium). If this advice is correct, we should see musicians with loyal user bases engaging more with their favourite artists and less with other music, suggesting a narrow targeting strategy would suffice. On the other hand, the established marketing laws indicate that the listeners of very different genres should overlap more than conventional wisdom would suggest, supporting the need for a much broader approach to targeting potential audiences. Given these conflicting views, musicians need to know if they should market to their existing listeners, the listeners of music similar to theirs (i.e., the same genre), or if they should try to reach a much wider audience. We turn to established choice patterns from the marketing literature to address these questions in the music context. This study examines 84,000,000 observations of music listening from 27,000 unique global users between 2013 and 2014 and survey data from 2019 containing music listening from over 1000 representative respondents in the United States. The results show that listening follows the Duplication of Purchase law for genres, artists, albums, and songs, at an annual, 6-months, 3-months, 1-month, and 1-week period, with no indication of partitioned music listening. The implication is that musicians should try to reach all potential listeners, regardless of what they already listen to. These findings contribute to the theoretical knowledge about duplication analyses of various durations, extend the contexts of choice behaviour that exhibit this pattern, and managerially, to knowledge about the extent of potential audiences and ‘share of ear’ competition.  相似文献

Five experiments examined the role of resource evaluability on giving. We systematically varied participants' resources they and another potential donor received and whether they could donate to a recipient either by themselves or with the other donor. Participants in the relative advantage condition received more resources than the other donor, and those in the relative disadvantage condition received fewer resources than the other donor. The presence of the other donor made participants' resources evaluable and shaped giving: Relatively disadvantaged participants were proportionally more generous than advantaged participants but only when they could evaluate their resources. Neither the mere presence of others nor reputational concerns could explain the results. Exploratory mediation and moderation analyses further showed that relatively disadvantaged participants give proportionally more the higher and the more equal they perceive their status to the advantaged donor. This shows that the generosity of those who have less does depend on how they evaluate their status compared to other donors. Our results provide insights into the question of why and when resource asymmetries between donors result in prosocial giving and can influence fundraising strategies of charitable organizations.  相似文献

Episodic memory decline is the prominent neuropsychological feature of typical Alzheimer's Disease (AD), for which current treatments have a limited clinical response. Recently, gamma entrainment therapy has been used as a non-invasive treatment in AD, providing evidence that it may have the potential to alleviate brain pathology and improve cognitive function in AD patients. At the same time, the precuneus (PC) has been recognized as a key area involved in AD related memory deficits and as a key node of the Default Mode Network. This study aimed to investigate the effectiveness of a 40 Hz Transcranial Magnetic Stimulation (TMS) intervention, delivered bilaterally to the precuneus for 10 days, in improving the patients' episodic memory performance. Secondary outcome variables investigated included general cognitive function, semantic and spatial memory, as well as attention and executive function. A concurrent multiple baseline design across five cases was employed. Four patients completed the study. Visual analysis combined with effect size indices were used to evaluate changes across phases. An increase in the average level of immediate recalled words was observed in three out of four patients. Effect size indices indicated significant improvement of attention skills in two patients. No treatment effect was observed for semantic and visual memory, or for executive function. An immediate treatment effect was observed in all patients' general cognitive function as assessed with the Alzheimer's Disease Assessment Scale (mean reduction of 5 points), which was maintained and improved further three months post-treatment. The neuropsychological evaluations indicated improved performance three months post-treatment in immediate and delayed recall, attention, phonological verbal fluency, anxiety, and neuropsychiatric symptoms. This study provides preliminary evidence for the efficacy of a novel non-pharmacological treatment using gamma-band TMS in addressing cognitive dysfunction in AD.  相似文献

Subjects evaluated three stimulus persons on several rating scales who were either 10%, 50%, or 90% similar to themselves in attitudes Subjects were divided into low, moderate, and high self-esteem groups on the basis of an earlier Q sort The results showed a strong positive relation between perceived similarity and positive attribution for each of the dependent variables, including liking, sophisticated, intelligent, sincere, happy, and a social distance scale A negative relation was obtained for two undesirable traits, arrogant and cynical Self-esteem interacted with similarity on several of the measures The difference between self-esteem groups was largely restricted to highly dissimilar stimulus persons Moderate esteem subjects were more favorable toward dissimilar persons than either of the other two groups, and the high and low groups tended to resemble each other more than either group resembled the moderate esteem group These results were discussed in terms of the relation between self-esteem and adjustment, and in terms of McGuire's (1968) theory that predicts a nonmonotonic relation between self-esteem and attitudes.  相似文献

A series of five experiments examined the effects of irrelevant speech on proofreading and memory. Four of the experiments used a proofreading task and showed that the deleterious effects of irrelevant speech: (1) depend on the speech being meaningful, (2) are only present when the burden on short-term memory is low and (3) are manifested in a lower detection rate for non-contextual as opposed to contextual errors. Neither the spatial location of the speech (either in terms of spatial dispersion of sources or spatial movement of a single source) nor the intensity of the speech (in a range bounded by 50 dB(A) and 70 dB(A)) had any effect on proofreading. Late selection models of attention are favoured by the results in preference to models having arousal, short-term memory or early selection in attention as their basis. A final experiment showed serial recall for visual lists to be impaired by the presence of any speech-like sound (including reversed speech and speech in an unfamiliar language) which suggests a set of phenomena qualitatively different from those associated with proofreading. Throughout the article the practical consequences of the findings are emphasized.  相似文献

Researchers have hypothesized that behavioral problems are accentuated when a shy person wants to be with other people. This need to be with others--sociability--is a related but separate construct from shyness. The purpose of the present study was to examine the relationship of shyness and sociability to illicit substance use in a sample of 654 male high school students. It was found that, in general, shy male adolescents were significantly more likely to use illicit substances when compared to those who were not shy. Those who were shy and highly sociable were significantly more likely to use hallucinogenic substances than were those who were shy and low to moderate in sociability as well as those who were not shy. Although not significant, there was a trend toward more cocaine and marijuana use among those who were shy and highly sociable. The implications of these findings for those who work with adolescents are discussed.  相似文献

The background, rationale, methodology and outcomes of a project on developing local lifelong guidance strategies in four areas are outlined. The main components of the strategies developed in the four areas are analysed, and a number of issues relating to the process of strategy development are addressed. Much of the lack of coherence at local level stems from lack of coherence at national policy level: implications for national policy are examined. Finally, implications for parallel work in other localities are explored.  相似文献
