  • Neuromusical Research: an Overview of the Literature
    In: Neurosciences in Music Pedagogy ISBN: 978-1-60021-834-7 Editors: W. Gruhn and F. Rauscher, pp. 1-25 © 2007 Nova Science Publishers, Inc. Chapter I NEUROMUSICAL RESEARCH: AN OVERVIEW OF THE LITERATURE Richard D. Edwards and Donald A. Hodges ABSTRACT With growing interest in the neuroscience of music among both neuroscientists and music educators, the task of reviewing the extant neuromusical research has become more exciting, if not a bit more complicated due to the diversity of topics and the increasing number of available studies. We provide an overview of neuromusical research by discussing its historical foundations (especially with the advancements of imaging technologies), support from ancillary areas (anthropology, ethnomusicology, ethology, and music psychology), support from fetal and infant responses to music, and support from studies of special musicians (prodigies, savants, Williams Syndrome musicians, and Alzheimer’s patients). The main section presents findings and implications from recent neuroimaging studies by dividing the research into five categories: (1) Perception and Cognition, (2) Affective Responses, (3) Musical Performance, (4) Learning, and (5) Genetic Factors. Several broad conclusions regarding the state of human musicality are presented in the concluding section. Among these conclusions, perhaps the most valuable evidence that neuromusical research currently holds for educators is that musicality is a birthright of all people and that music processing is inherent to some degree in all humans. Humanity has long wondered about the mind. Before Descartes proposed “I think, therefore, I am” or even before Plato and Aristotle ever contemplated the psyche, the oldest brain map on record was being drawn upon papyrus in Egypt almost 5,000 years ago1.

Ross Milligan College A Paper Presented at the Annual Conference of the Mid - South Educational Research Association, Starkville, Mississippi, November 8 - 10, 2017 COMPUTERIZED AND TRADITIONAL EAR TRAINING 2 Abstract The purpose of this study was to investigate the effects of computerized and traditional ear t raining methods on the aural skills abilities of elementary music students. The sample consisted of 20 students who were randomly assigned to either an experimental or control group. The experimental group was taught for five sessions using computerized ea r training program while the control group was taught for five sessions using traditional, non - computerized ear training methods. At the end of the five sessions, students were tested. Data were collected by administering a test to both experimental and co ntrol groups that measured students’ ability to identify by ear eleven different pitch intervals and three different qualities of chords. Students were also administered a survey to measure their attitudes toward their experience in the ear training progra m. Data were analyzed using independent t - tests. The results indicated a significant difference between the test scores of the control and experimental groups.

  • Irrelevant Sound Interference on Phonological and Tonal Working
    Defilippi et al. Psicologia: Reflexão e Crítica (2019) 32:2 Psicologia: Reflexão e Crítica https://doi.org/10.1186/s41155-018-0114-z RESEARCH Open Access Irrelevant sound interference on phonological and tonal working memory in musicians and nonmusicians Ana Clara Naufel Defilippi, Ricardo Basso Garcia* and Cesar Galera Abstract Background: Working memory refers to the cognitive system responsible for the temporary storage and maintenance of information, but it remains controversial whether overlapping processes underlie the temporary retention of verbal and musical information such as words and tones. Methods: Participants with little or no musical training (n = 22) and professional musicians (n = 21) were administered four memory tasks. Two tasks (tone sequence recognition and pseudoword sequence recall) aimed at comparing groups’ performance for tonal or phonological material separately. Other two memory tasks investigated pseudoword and tone recognition under three conditions during the retention interval (silence, irrelevant words, or irrelevant tones). Results: Musicians were better than nonmusicians in tone sequence recognition but not in pseudoword sequence recall. There were no interference effects of irrelevant tones or words on pseudoword recognition, and only irrelevant tones significantly interfered with tone recognition. Conclusions: Our results offer further support that tone recognition is specifically impaired by irrelevant tones, but irrelevant words did not disrupt pseudoword or tone recognition. Although these results

  • Interference in Memory for Tonal Pitch: Implications for a Working-Memory Model
    MeITWry de Cognition 1992. 20 (3), 314-320 Interference in memory for tonal pitch: Implications for a working-memory model THOMAS PECHMANN and all..BERT MOHR Unioersitiit des Saarlandes, Saarbriicken, Germany The degree of interference caused by different kinds of stimuli on memory for tonal pitch was studied. Musically trained and untrained subjects heard a sequence of two tones separated by an interval of 5 sec. The tones were either identical in pitch or differed by a semitone. Subjects had to decide whether the tones were identical or not. The interval was filled with tonal, verbal, or visual material under attended and unattended conditions. The results revealed clear group differences. Musically trained subjects' retention of the first test tone was only affected by the interposition of other tones. In contrast, the performance of musically untrained subjects was also affected by verbal and visual items. The findings are discussed in the framework ofBaddeley's (1986) working-memory model. In a number of experiments, Deutsch studied the ef­ Deutsch & Feroe, 1975).

The basilar membrane therefore responds best to high frequencies where it is narrow and thin at the base and to low frequencies where it is wide and thick at the apex. Welcome back. Handbook of Clinical Audiology. Sometimes it is important to be able to calculate an estimate of the equivalent sound level experienced over a period of time. In order to obtain an estimate of the sound pressure level it is necessary to average over at least one cycle, and preferably more, of the sound waveform. Suppose two pure tones, or sine waves, with amplitudes A1 and A2 and frequencies F1 and F2 respectively are sounded together. Psychoacoustics is a developing field of research. Readers should check their local regulations for noise exposure in practice. There are two different situations which must be considered when adding sound levels together. This book is not yet featured on Listopia. Firstly, we must work out the radiating area of the loudspeaker which is: 0. The delays are very small and so these effects occur at high audio frequencies, typically above 5 kHz. Ideally one would like a filter which has a fast time response and a narrow bandwidth, but this is impossible. Instead they take a finite frequency range to attenuate the signal. Automated room correction routines are more of a band-aid for flawed loudspeakers rather than an improvement for typical room acoustics.
