The Place of Women in Psychology.

Comments on the analysis by Florence Denmark (December 1980) on the place of women in psychology and their lack of recognition and compensation, despite considerable achievement, and discusses parallels in the field of music. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Metaphors from music criticism.

"A vocabulary of metaphorical terms used to describe voice qualities was drawn from the writings of four music critics. The Ss who were not well informed about music listened to recordings of nine operatic voices and assigned terms from the metaphorical vocabulary to these voices. Many of the words were used with agreement and discrimination. Factor analysis of the results yielded three factors [evaluation, potency, activity] similar to those found in the more general factor analysis of linguistic meaning made by Osgood and Suci."

Pitch-Dependent Identification of Musical Instrument Sounds

This paper describes a musical instrument identification method that takes into consideration the pitch dependency of timbres of musical instruments. The difficulty in musical instrument identification resides in the pitch dependency of musical instrument sounds, that is, acoustic features of most musical instruments vary according to the pitch (fundamental frequency, F0). To cope with this difficulty, we propose an F0-dependent multivariate normal distribution, where each element of the mean vector is represented by a function of F0. Our method first extracts 129 features (e.g., the spectral centroid, the gradient of the straight line approximating the power envelope) from a musical instrument sound and then reduces the dimensionality of the feature space into 18 dimension. In the 18-dimensional feature space, it calculates an F0-dependent mean function and an F0-normalized covariance, and finally applies the Bayes decision rule. Experimental results of identifying 6,247 solo tones of 19 musical instruments shows that the proposed method improved the recognition rate from 75.73% to 79.73%.

Measurement of music achievement at college entrance.

The development of the Aliferis Music Achievement Test, which in its final edition consists of 26 melodic items, 18 harmonic items, and 20 rhythmic items, is described. Distributions of test mean scores for a national sample of college music students are given by geographic region and type of institution. For a sample of 177 Ss, correlations between freshman honor-point ratios in music courses and test scores were .54 (melodic), .41 (harmonic), .46 (rhythmic), and .61 (total score).

"Arousal hypothesis" and the effects of music on purchasing behavior.

Replicates, in a naturalistic setting, a prior finding which supported that portion of the "arousal hypothesis" which predicts that a certain degree of noise will actually increase activity. Music was varied from loud to soft in 8 counterbalanced experimental sessions in 2 large supermarkets (N = 1100). The "arousal hypothesis" seems to account for the results: significantly less time was spent in the markets during the loud session, although there was no significant difference in sales, nor in the customers' reported satisfaction.

Enhancement of Spatial Learning-Memory in Developing Rats via Mozart Music

This paper studies the effect of musical stimulations on the capability of the spatial learningmemory in developing rats by behavioral and electrophysiological techniques. Rats, which are exposed to Mozart's Sonata for Two Pianos in D Major, complete learning tasks of the Moriss water maze with significantly shorter latencies, and the power spectrum of alpha band of electrohippocampogram (EHG) significantly increase, compared with the control rats and rats exposed to the horror music. The results indicate that if given the stimulation of Mozart music in the developmental period of the auditory cortex, the capability of the spatial learning-memory can be significantly changed. The enhancement of alpha band of EHG may be related to the change of this function mainly.
