To study the perceptual structure of musical timbre and the effects of musical training, timbral dissimilarities of synthesized instrument sounds were rated by professional musicians, amateur musicians, and nonmusicians. The data were analyzed with an extended version of the multidimensional scaling algorithm CLASCAL (Winsberg & De Soete, 1993), which estimates the number of latent classes of subjects, the coordinates of each timbre on common Euclidean dimensions, a specificity value of unique attributes for each timbre, and a separate weight for each latent class on each of the common dimensions and the set of specificities. Five latent classes were found for a three-dimensional spatial model with specificities. Common dimensions were quantified psychophysically in terms of log-rise time, spectral centroid, and degree of spectral variation. The results further suggest that musical timbres possess specific attributes not accounted for by these shared perceptual dimensions. Weight patterns indicate that perceptual salience of dimensions and specificities varied across classes. A comparison of class structure with biographical factors associated with degree of musical training and activity was not clearly related to the class structure, though musicians gave more precise and coherent judgments than did nonmusicians or amateurs. The model with latent classes and specificities gave a better fit to the data and made the acoustic correlates of the common dimensions more interpretable. 相似文献

Objections to Rational-Emotive Behavior Therapy (REBT) seem to exceed the mere rational preference for one approach over another. Ziegler suggested that James's dichotomy between Tough- and Tender-Mindedness might explain REBT's appeal to some and its failure to attract others. REBT is a predominantly Tough-Minded therapy, but the counseling profession is largely Tender Minded. In this article, the author examines why Tender-Minded counselors may not accept REBT, what common misperceptions of REBT may contribute to this rejection, and how the two might be reconciled. Intervention strategies for Tender-Minded counselors are suggested. 相似文献

The pace, shape and meaning of development are cultural phenomena—fundamentally driven by the meanings people ascribe to their
action, to the symbols they aspire to, and by the wider values contexts within which they are acting. However, people participating
within the development process continuously confront a tension between the assertion of the cultural meanings of the local
known social world and the assertion of the meanings of an idealized largely unknown social world that stretches beyond immediate
experience, and that is particularly represented in commodity symbols and media images. Tension is therefore between indigenization
or globalization. The product, greater valence of indigenization or globalization, results from the alternative ways in which
tension between the two domains is resolved.
In the modern social world access to knowledge, as well as the impact of knowledge embodied within technological artifacts,
are key drivers in both the level of participation in development and the level of colonization of indigenized meanings by
globalized frameworks of understanding. The current paper therefore focuses on the role of knowledge within the interactions
between globalization and indigenization.
The paper demonstrates that the general trend of development during the last half of the twentieth century has driven cultural
change towards more globalized meanings and dependencies. The dynamics of technological access and change are centrally implicated.
However, new opportunities are opening up at both local indigenized levels and within modernizing sectors, and the essence
of these opportunities lies in capturing a cultural advantage. At the indigenous society level, a focus on capitalizing on
indigenous technical knowledge can have enormous payoffs in terms of economic development outcomes. Meanwhile, a focus on
linking local with modernizing sectors through bridging technologies and knowledge across indigenous and global cultures allows
indigenous cultures to share in the economic benefits of modernization. And finally, a new wave of change is emerging in the
modernized sector itself, opening up quite new opportunities for “small players”—whether they be small firms or small countries.
The opportunities are set within change in the global orders of technology and science over the last five to ten years. What
matters is the ability of these small players to be highly responsive, to capture knowledge flows through both technical and
social capabilities of their people; in other words, global advantage follows from capture of local cultural strength.

The four experiments reported here provide evidence that (1) misleading postevent suggestions can impair memory for details in a witnessed event and (2) subjects sometimes remember sug-gested details as things seen in the event itself. All four experiments used recall tests in which subjects were warned of the possibility that the postevent information included misleading sug-gestions and were instructed to report both what they witnessed in the event and what was men-tioned in the postevent narrative. Recall of event details was poorer on misled items than on control items, and subjects sometimes misidentified the sources of their recollections. Our re-sults suggest that these findings are not due to guessing or response biases, but rather reflect genuine memory impairment and source monitoring confusions. 相似文献

Is the size of a semantic-priming effect a function of the strength of the semantic context? This issue was examined in four studies using a single categorically related prime as the weaker context and four categorically related primes as the stronger context. Results indicate that, independently of prime-target SOA, four primes provide a larger priming effect than a single prime in a lexical-decision task, but not in a naming task. These data provide further support for the argument that different mechanisms mediate priming in the two tasks. In particular, only the lexical-decision task appears to be susceptible to higher-level processes that can be influenced by the number of primes. Priming in a naming task appears to be driven by more automatic processes. Possible accounts of this multiple-prime advantage in lexical-decision tasks are considered. 相似文献

A variant of the standard deductive tableau system is introduced, and interrogative rules are added, resulting in a so-called interrogative tableau system. A game-theoretical account of entailment is sketched, and the deductive tableau system is interpreted in these terms. Finally, it is shown how to extend this account of entailment into an account of interrogative entailment, thereby providing a semantics for the interrogative tableau system. 相似文献

Although the Rescorla-Wagner model is widely taught in learning courses, most textbooks present a simplified version that does not contain all of its parameters. On the basis of Rescorla and Wagner 1972) and the Turbo PASCAL program by Lachnit, Schneider, Lipp, and Kimme! (1988), we created a simulation using STELLA-II, an icon-based program by High Performance Systems, Inc. We argue that this simulation facilitates teaching the complete Rescorla-Wagner model. Using trans-switching (Kimmel & Ray, 1978; Lachnit, 1986; Murrin & Kimmel, 1986) as an example, we demonstrate the effectiveness of the STELLA-II version of the Rescorla-Wagner model as a heuristic tool. 相似文献
