AbstractSterba and Bauer's Keynote Article discusses the blurred distinction between theoretical principles and analytical methods in the person-oriented approach as problematic and review which of the person-oriented principles are testable under the four types of latent variable models for longitudinal data. Although the issue is important, some arbitrariness exists in determining whether a given principle can be tested within each analytic approach. To close the gap between person-oriented theory and methods and to extend the person-oriented approach more generally, it is necessary to embrace both variable-oriented and person-oriented methods because it is not the individual analytic methods but how studies are implemented as a whole that defines the person-oriented approach. Three areas in developmental psychopathology are discussed in which variable-oriented and person-oriented methods can be complementary. The need to better understand the target system using an appropriate person-specific tool is graphically illustrated. Several concepts of dynamic systems such as attractors, phase transitions, and control parameters are illustrated using experimentally perturbed cardiac rhythms (heart rate variability) as an example in the context of translational alcohol research.

Response Direction

Music has been associated with alterations in autonomic function. Tempo, the speed of music, is one of many musical parameters that may drive autonomic modulation. However, direct measures of sympathetic nervous system activity and control groups and/or control stimuli do not feature in prior work. This article therefore reports an investigation into the autonomic effects of increases and decreases in tempo. Fifty-eight healthy participants (age range: 22–80 years) were randomly allocated to either an experimental ( n = 29, tune) or control (rhythm of the same tune) group. All participants underwent five conditions: baseline, stable tempo (tune/rhythm repeatedly played at 120 bpm), tempo increase (tune/rhythm played at 60 bpm, 90 bpm, 120 bpm, 150 bpm, 180 bpm), tempo decrease (tune/rhythm played at 180 bpm, 150 bpm, 120 bpm, 90 bpm, 60 bpm) and recovery. Heart rate, blood pressure, respiration, and muscle sympathetic nerve activity were continuously recorded. The 60 bpm in the tempo decrease stimulus was associated with increases in measures of parasympathetic activity. The 180 bpm in the tempo increase stimulus was also associated with shifts towards parasympathetic predominance. Responses to the stimuli were predicted by baseline %LF. It is concluded that the individual tempi impacted upon autonomic function, despite the entire stimulus having little effect. The 60 bpm in an increasingly slower stimulus was associated with greater vagal modulations of heart rate than faster tempi. For the first time, this study shows that response direction and magnitude to tempo manipulations were predicted by resting values, suggesting that music responders may be autonomically distinct from non-responders.

To investigate dobutamine-induced cardiac adaptations, we compared dobutamine-treated with swim-trained and sedentary control rats. After 14 wk of treatment, heart rate was lower in the dobutamine-treated (279 +/- 6) and exercise-trained (287 +/- 4 beats/min) groups than in the control animals (305 +/- 3 beats/min; P less than 0.05). The exercised rats gained less weight (164 +/- 11 g; P less than 0.05) than the dobutamine-treated (238 +/- 16 g) and the control animals (231 +/- 12 g). Also, compared with the two other groups, the exercise group had higher relative heart weights (3.47 +/- 0.08 vs. 2.82 +/- 0.06 and 2.90 +/- 0.05 g/kg in the dobutamine and control groups, respectively; P less than 0.05) and lower epididymal fat pad weights (6.6 +/- 0.4 vs. 13.3 +/- 1.0 and 11.4 +/- 0.5 g/kg in the dobutamine and control groups, respectively; P less than 0.05). However, both the maximum heart rate produced by isoproterenol and the isoproterenol dose producing 50% of the peak heart rate response were similar among the three groups. Myocardial norepinephrine content, beta-adrenergic receptor number, and adenylate cyclase activation by isoproterenol, NaF, 5'-guanylyl imidodiphosphate, and forskolin also did not differ. Thus, although there were differences between the dobutamine-treated and the exercised rats, the two groups were similar in that they developed bradycardia that was not due to cardiac adrenergic desensitization.
