Neural mechanisms involved in the oral representation of percussion music: An fMRI study

Numerous music cultures use nonsense syllables to represent percussive sounds. Covert reciting of these syllable sequences along with percussion music aids active listeners in keeping track of music. Owing to the acoustic dissimilarity between the representative syllables and the referent percussive sounds, associative learning is necessary for the oral representation of percussion music. We used functional magnetic resonance imaging (fMRI) to explore the neural processes underlying oral rehearsals of music. There were four music conditions in the experiment: (1) passive listening to unlearned percussion music, (2) active listening to learned percussion music, (3) active listening to the syllable representation of (2), and (4) active listening to learned melodic music. Our results specified two neural substrates of the association mechanisms involved in the oral representation of percussion music. First, information integration of heard sounds and the auditory consequences of subvocal rehearsals may engage the right planum temporale during active listening to percussion music. Second, mapping heard sounds to articulatory and laryngeal gestures may engage the left middle premotor cortex.     

Structural equation modeling of approval voting data

The method of approval voting is a commonly used voting procedure in which each judge selects a subset of the alternatives. By postulating that the random utilities associated with the choice options in approval voting elections follow a multivariate normal distribution under the Thurstonian framework, Regenwetter, Ho, and Tsetlin (2007) attempted to integrate the normative theories and individual variabilities in modeling social behavior. However, their approach is limited to only three alternatives, due to computational intractability as the number of alternatives increases. In this article, we reparameterize extensions of their models under the structural equation modeling framework and propose the use of limited information methods for estimating model parameters. As a result, we are able to extend their previous approach to the analysis of approval voting data with any number of alternatives. Two applications are presented to illustrate the usefulness of such an approach.     

Impact of signals and experience on trust and trusting behavior

Trust is an essential factor that drives virtual interaction and transactions on the Internet. Researchers have investigated the trust development process, and identified several important factors that form the basis for trust. This research combines the signal perspective and trust theory to examine the impact of market signals and past experience on trust formation and trusting behavior. Three market signals, including brand image, Web-site investment, and privacy policies, are identified and empirically tested to determine their impact on consumer trust. Based on 322 active Web users, the quantitative results suggest that brand image, Web-site investment, privacy policies, and past experience all positively impact trust formation. Furthermore, trust shows a positive effect on Web-site stickiness. Both theoretical and practical implications of the results are also offered.     

Relation of perfectionism with athletes' burnout: further examination

The purpose was to examine the different aspects of perfectionism and athletes' burnout. College athletes (N = 320) with mean age of 19.7 yr. (SD = 1.4) completed the Chinese version of the Multiple Perfectionism Scale for Sport and the Eades' Athlete Burnout Inventory. Results indicated that perfectionism could be separated into adaptive and maladaptive perfectionism. Adaptive perfectionism was linked to reduced athletes' burnout while maladaptive perfectionism was associated with athletes' burnout. In addition, significant interaction was found between adaptive perfec tionism and maladaptive perfectionism on athletes' burnout. Results suggest that high maladaptive perfectionism and low adaptive perfectionism corresponds to higher scores on athletes' burnout. Perfectionism should not be treated as an all-or-nothing disposition. The extent of athlete burnout can vary with the interaction effects of the two types of perfectionism. In terms of practical implications in intervention work, coaches and sport psychologists should try to reduce athletes' maladaptive perfectionism and increase adaptive perfectionism.     

Conscious and unconscious forms of memory in different implicit tests

This study investigated how shallow processing (complexity rating), deep processing (pleasantness rating), and semantic generation (translating from English) of Chinese words affects conscious memory (CM) and unconscious memory (UM) of the words with three implicit tests: word association, word identification, and word-stem completion. A metacognition-based dissociation procedure was used to estimate the two forms of memory for each test. Except for the shallow condition preceding the word-association test, all three study conditions produced a positive effect on the estimate of CM. The estimate of UM did not benefit from any of the study conditions in the word-association test, it benefited from the shallow and deep conditions but did not benefit from the generation condition in the stem-completion test, and it benefited from the shallow condition but did not benefit from the deep and generation conditions in the word-identification test. Implications of these results for CM and UM operations are discussed.     

Gender differences in Taiwan university students' attitudes toward Web-based learning.

This study explored gender differences on university students' attitudes toward Web-based learning in Taiwan. A Web-based Learning Attitude Survey (WLAS) was developed. The WLAS consisted of five scales, including access, social structure, content, pedagogy, and community relationship toward Web-based learning. By using an online survey, this study gathered the responses of 1,866 Taiwanese university students (940 males and 926 females) whose ages ranged from 18 to 23. The results showed significant gender differences in the aspects of social structure, content, and community relationship involved in Web-based learning. Interestingly, although females might consider the Internet a masculine-dominated technology, they displayed more favorable attitudes than males did regarding the impacts of socioeconomic status (the social structure scale) on students' performance of Web-based learning. Moreover, females possessed more positive attitudes than males toward the helpfulness and variety of the content for Web learning. However, they did not think the virtual interaction on the Internet could develop adequate teacher-student and peer relationships (the community relationship scale). Some follow-up interviews were also conducted with selected students, and the implications derived from this study were discussed.     

Risk perception in Taiwan

In a questionnaire study, 51 Taiwanese college students were asked to judge 48 natural and human-made hazards on nine risk characteristics. Another group of 61 students were asked to rate the magnitude of 80 hazards and their attitudes toward these hazards. To evaluate the dimensionality of risk perception, participants' ratings for the nine risk characteristics were analyzed using Profile Analysis via Multidimensional Scaling approach. Two dimensions of risk perception were identified: (i) Involuntary versus Immediate Effect; and (ii) Delayed Effect versus Known to Science and Chronic. The relationships of risk perceptions and perceived public and private responsibilities in risk management were examined. Catastrophic, certain-to-be-fatal, dreaded, and uncontrollable risks were perceived as more deserving of public risk management, while controllable risks that were known to science, known to those exposed, and chronic were perceived as more deserving of private management. In particular, diseases are perceived as most deserving of private risk management and least deserving of public risk management; and technologies are perceived as most deserving of public risk management and least deserving of private risk management.     

Modeling Customer Loyalty from an Integrative Perspective of Self-Determination Theory and Expectation–Confirmation Theory

Purpose  This research conceptualizes and tests an integrative model of customer loyalty by linking two important theories: expectation–confirmation theory and self-determination theory. Design/Methodology/Approach  The model is examined using data obtained from 207 part-time students who have encountered the service of a skincare and beauty salon in Taiwan. These students work as full-time professionals in a variety of industries during the daytime and are financially independent for their daily consumption. Findings  The empirical results of this study indicate that loyalty is positively influenced by both intrinsic regulation and identified regulation, while introjected regulation and external regulation are insignificantly related to loyalty. Affected positively by service expectation and service confirmation, satisfaction has positive influences on all four dimensions of self-determined motivation—namely, intrinsic regulation, identified regulation, introjected regulation, and external regulation. Implications  The findings of this study show that the proposed model helps to learn about loyalty formation and its mediating mechanism in service contexts. Intrinsic regulation and identified regulation may be applied as two potential checkpoints for management to learn the actual status of customer loyalty based on a constant service quality offered by the service provider. Originality/Value  This study is one of the earliest to integrate expectation–confirmation theory and self-determination theory to explore loyalty. Besides, this study transplants the traditional application of self-determination theory from educational service to commercial service in general so that efficient strategies can be made for boosting loyalty.
