I that the disclosure of emotions can have positive consequences for individuals-that emotional disclosure is a Good Thing like democracy, mother, and an annual physical. But, although contemporary psychologists may view emotional disclosure as a Good Thing, this has not been the prevailing view in much of Western thought nor even in twentieth century psychology. For example, the psychologists who first studied human intelligence contrasted rational thought with emotional experience (Schaffer, Gilmer,
For years, affect researchers have debated about the true dimensionality of mood. Some have argued that positive and negative moods are largely independent and can be experienced simultaneously. Others claim that mood is bipolar, that joy and sorrow represent opposite ends of a single dimension. The 3 studies presented in this article suggest that the evidence that purportedly shows the independence of seemingly opposite mood states, that is, low correlations between positive and negative moods, may be the result of failures to consider biases due to random and nonrandom response error. When these sources of error are taken into account using multiple methods of mood assessment, a largely bipolar structure for affect emerges. The data herein speak to the importance of a multi-method approach to the measurement of mood.
This study examines measures of the glottal airflow waveform, the electroglottographic signal (EGG), amplitude differences between peaks in the acoustic spectrum, and observations of the spectral energy content of the third formant (F3), in terms of how they relate to one another. Twenty females with normal voices served as subjects. Both group and individual data were studied. Measurements were made for the vowel in two speech tasks: strings of the syllable /pæ/ and sustained phonation of /æ/, which were produced at two levels of vocal effort: comfortable and loud voice. The main results were:
1. Significant differences in parameter values between /pæ/ and /æ/ were related to significant differences in the sound pressure level (SPL).
2. An “adduction quotient,” measured from the glottal waveform at a 30% criterion, was sensitive enough to differentiate between waveforms reflecting abrupt versus gradual vocal fold closing movements.
3. DC flow showed weak or nonsignificant relationships with acoustic measures.
4. The spectral content in the third formant (F3) in comfortable loudness typically consisted of a mix of noise and harmonic energy. In loud voice, the F3 spectral content typically consisted of harmonic energy.
5. Significant differences were found in all measures between tokens with F3 harmonic energy and tokens with F3 noise, independent of loudness condition.
6. Strong relationships between flow- and EGG-adduction quotients suggested that these signals can be used to complement each other.
7. The amplitude difference between spectral peaks of the first and third formant (F1-F3) was found to add information about abruptness of airflow decrease (flow declination) that may be lost in the glottal waveform signal due to low-pass filtering.
The results are discussed in terms of how an integrated use of these measures can contribute to a better understanding of the normal vocal mechanism and help to improve methods for evaluating vocal function.
Psychosocial factors long have been associated with the development of hyperfunctional voice disorders such as vocal nodules. However, experimental evidence concerning the role of these factors in the etiology of vocal nodules specifically is sparse. The present study represents a preliminary examination of some psychosocial factors for 3 groups of adult female subjects: 27 with vocal nodules, 17 with hyperfunctionally related voice disorders other than nodules (pathological control), and 33 with no history of voice disorders (normal control). Four psychosocial factors were studied: stress (measured by the Social Readjustment Rating Questionnaire), anxiety (measured by the State-Trait Anxiety Inventory), voice use, and somatic complaints (both measured by our own instruments). Relative to the normal control group, the patients with nodules showed significantly increased scores on all factors except stress. The pathological control group showed significantly increased scores on all factors except voice use. No significant differences were found between the group with nodules and the pathological control group on any factor. The results are discussed in terms of their implications for clinical practice and future research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
