Psychmuse: A Macintosh system for psychomusicology research

A software system developed with HyperCard has been designed to support research relying on musical stimuli. The software accesses a set of digitized sounds in memory that consist of chromatic scale notes for the piano, harp, and guitar. Menu options allow experimenters to create monophonic melodies, to arrange melodies in a prescribed order, and to present them in a flexible format for a variety of psychological tasks. In addition to supporting experimental research projects, the software can also be used to demonstrate certain fundamental principles of auditory perception and cognitive psychology.     

Some structural determinants of melody recall

Sophisticated musicians were asked to recall, using musical notation, a set of unfamiliar folk tunes that varied in rhythmic structure and referents of tonality. The results showed that memory was facilitated by tonic triad members marking phrase endings, but only when their presence was highlighted by a corresponding pattern of temporal accents. Conversely, recall significantly declined when tonal information was either absent or obscured by rhythmic structure. Error analyses further revealed that the retention of overall pitch contour and information at phrase ending points varied as a function of these manipulations. The results are discussed in terms of a framework that links the acts of perceiving and remembering to a common attentional scheme.     

TOWARD A SOUND PERSPECTIVE ON MODERN PHYSICS: CAPRA'S POPULARIZATION OF MYSTICISM AND THEOLOGICAL APPROACHES REEXAMINED

Abstract. Fritjof Capra's The Tao of Physics , one of several popularizations paralleling Eastern mysticism and modern physics, is critiqued, demonstrating that Capra gives little attention to the differing philosophies of physics he employs, utilizing whatever interpretation suits his purposes, without prior justification. The same critique is applied and similar conclusions drawn, about some recent attempts at relating theology and physics. In contrast, we propose the possibility of maintaining a cogent relationship between these disciplines by employing theological hypotheses to account for aspects of physics that are free from interpretive difficulties, such as the ability to create mathematical structures with extraordinary predictive success.     

Attending to simple auditory and visual signals

Rutgers-The State University, New Brunswick, New Jersey 08903 Is the quality of information obtained from simple auditory and visual signals diminished when both modalities must be attended to simultaneously? This question was investigated in an experiment in which subjects made forced-choice judgments of the location of simple light and tone signals presented in focused- and divided-attention conditions. The data are compared with the predictions of a model that describes the largest performance decrement to be expected in the divided-attention condition on the basis of nonattentional factors. The results of this comparison suggest that the difference in performance between focused- and dividedattention conditions is attributable solely to the increased opportunity to confuse signal with noise as the number of modalities is increased. Thus, there appears to be no evidence that dividing attention between modalities affects the quality of the stimulus representations of individual light and tone signals.     

Family Sculpting: I. Some doubts and some possibilities

Family sculpting is reviewed within the context of general doubts that confront family therapy, in particular the need for a certain act of faith in therapy, and the search for some sort of underlying theory. Family sculpting is most often used in reference to the psychoanalytic tradition of family therapy, but here the case is made for more serious attention to structural approaches. The potential of family sculpting is further explored in a number of other respects: its concreteness, its portrayal of ambiguity and its use with students, workers and other groups.     

Planning units and syntax in sentence production

The study was conducted to determine, first, whether it is the deep or the surface clause that is more important as a speech planning unit, and second, whether syntactic decisions are made during sentence production. Subjects, while talking, heard tones to which they had to respond by pressing a button; reaction times to these tones were taken as an index of processing load during production. It was found that there were increased RTs at the ends compared with the beginnings of deep structure clauses. No difference was found between RTs at the beginnings and ends of surface clauses not corresponding to a deep clause. The results were interpreted as showing that deep clauses are major planning units and that some planning for clauses occurs at the end of the preceding clause. Differences were found between RTs during clauses of different syntactic structure. These results were interpreted as indicating that syntax influences production and were discussed in relation to previous studies of pausing and speech disruption.     

Semantic satiation revisited with a lexical decision task

The semantic satiation hypothesis suggests that continuous verbalization of a word leads to a reduction in its meaning. This hypothesis was examined by having subjects repeat a priming word either once or for 30 sec prior to making a word-nonword lexical decision about a visually presented target. The primes were associated with (Experiments 1 and 3), identical to (Experiment 2), or unassociated with the word targets. As is usually found, target lexical decision times were significantly facilitated by oral priming with both the associated and identical words. While the magnitude of this facilitation effect was reduced slightly by continuous repetition of the prime in Experiment 1, no such reduction was observed in Experiments 2 and 3. These results are discussed in the context of a two-factor theory of semantic processing with the aid of Mortons logogen model. It was concluded that semantic satiation may not be semantic at all.     

A comparison of adult males' and females' interactions with girls and boys

The verbal interactions of adult males and females with trained girl and boy confederates were compared in an unstructured and an immediately following structured situation. Women did not respond differently based on the child's gender in either situation, while men spoke more and used longer mean length of utterances with the boys than with the girls in the unstructured situation. In the structured situation males did not respond differently to girls and boys, speaking more to both than did females. Correlations between the number of words spoken in female-child pairs were higher, suggesting a greater reciprocity of interaction, than for male-child pairs in both situations. The results are seen as reflecting the outcome of differential sex-role socialization for men and women, especially with respect to children, with females socialized to relate with others and men to need to dominate others.
