“…What is needed to compute such correlations is a single index of mood change frequency. Work is proceeding on methods of describing the frequency characteristics of temporally distributed variables, using such techniques as autoregressive parameter estimation as well as topographical analysis (Cacioppo & Dorfman, 1985). Nevertheless, the ANOVA findings reported suggest that spectral estimates of mood change frequency and within-subjects standard deviation estimates of mood change magnitude provide information that is somewhat independent.…”

Emotional variability is considered by many personologists a theoretically important characteristic of persons. Variability is conceptualized as frequent and extreme changes in mood or emotion over time. Many researchers index mood variability by a within-subjects standard deviation computed from mood ratings provided by single subjects on several occasions. In this article, 1 argue that this index is theoretically limited because it refers mainly to the average extremity of mood change and not the frequency of change. Because the frequency of change is important to any theory concerning emotional variability, I suggest that time-series techniques be used to better represent this aspect of the construct. The studies here illustrate how one class of time-series techniques-spectral analysis-can be applied to daily mood measures to index the frequency of mood shifts. The convergent validity of spectral estimates of mood change frequency is assessed relative TO self-report and parental-report measures of emotional reactivity. The divergent validity of the spectral estimates of mood change frequency is assessed by examining their relation to the within-subjccts standard deviation computed from daily mood assessments. Results suggest that the spectral approach provides an adequate index of mood change frequency that is independent of mood change extremity, helps clarify the meaning of emotional variability, and provides a new class of analytic strategies for inclusion in the idiographic-nomothetic paradigm.Variability in behavior and emotion has attracted the attention of personologists working within widely different traditions. These investigators have all assumed that variability is an inherent and stable characteristic of persons. For example, Henry Murray (1938Murray ( /1981 wrote, "In studying a person over[time], it is assumed, as an approximation, that his personality remains potentially the same. The sometimes marked inconsistencies that occur are put down to the subject's characteristic range of variability, itself an attribute of personality" (p. 110, emphasis added). Fiske (1961) observed, "Holding constant the general conditions and the specific stimuli, we can observe dependable individual differences in variability of response" (p. 340, emphasis added). In a discussion of emotion, Cattell (1973) suggested that "A general tendency to fluctuate . . .exists as a personality trait" (p. 225).Although many investigators are concerned with processes of change and variability, agreement as to what are satisfactory procedures for denning and studying variability is far from widespread (Zevon & Rounds, 1985). Thus, even though many would agree that variability, particularly emotional variability, I wish to thank Jerry Busemeyer, Ed Diener, Alexander Von Eye, and two anonymous reviewers for their helpful comments on an earlier version of this article. Conversations with Robert Bohrer and John Grottman also contributed to ideas developed in this article.

“…In fact, if we divide the power at each frequency by the total power, the power spectrum is thereby transformed to a probability density function. Hence, the moment-based indicants can be computed in the frequency domain without special attention or restrictive assumptions (Cacioppo & Dorfman, 1984). In accord with the points made earlier with regard to the time and amplitude domains, the moments of frequency uniquely and fully characterize the power spectrum.…”

to take an interest in psychophysiology through his work with Curt Sandman. His first article in Psychophysiology was published in 1978 with Sandman and was on the effects of heart rate biofeedback on attitude change. Thus began the marriage of John's abiding commitment to the objective study of the social world and biology, a quest that he continues to pursue today.John has worked on a breathtaking range of questions, and with each new question he adopts the methods that are needed to answer that question. And these methods are not only psychophysiological. In an article of which John was first author that was published in 1981, he analyzed the content and design of birthday cards for sons and daughters to examine gender differences in cultural values.In his development of social psychophysiology, John pursued many different issues with a broad range of methods. If the methods required were new to him, not only did he master them, but he inevitably ended up making a major contribution to the understanding of the methods themselves in addition to the original substantive question. For example, early on in his career, John began to use electromyography to examine affective and related processes. His 1981 article in American Psychologist on this topic was a major contribution to the biobehavioral sciences in introducing EMG as a useful measure to address a range of important psychological phenomena. Then in 1986, with Fridlund, he published a Guidelines article for EMG research in Psychophysiology.Throughout his career, in addition to his penetrating empirical research program and the conceptual advances in methodology have accompanied it, John has also published a number of seminal articles that go right to heart of psychophysiology-how we can make psychological inferences from physiological or biological data. His sophisticated and eloquent commentary on these matters has been monumental in educating new students and reminding established investigators of the conceptual minefields that lie before us in our quest to understand the relationship of biology and mind. His 1990 article with Tassinary in American Psychologist was one of his early efforts to articulate the several ways in which psychological constructs can be related to physiology. This effort has continued with his penetrating essay also published in American Psychologist six years later with Sarter and Berntson on brain imaging.John was on the faculty at the University of Iowa from 1979 through 1989, and this was the decade of social psychophysiology for him. He almost single-handedly launched this as a respectable and important subdiscipline and made novel contributions to our understanding of several social processes by using psychophysiological measures. John also began leading the NSF-funded Summer Institutes in Psychophysiology during these years, and, for many investigators who are now regular contributors to the psychophysiology literature, John's teaching efforts were instrumental in furthering their careers.During his time at Iowa he also put ...
