Dynamics and Correlates of Microscopic Changes in Affect

摘要: How are momentary microscopic assessments of behavioral dynamics related to traditional macroscopic, static measures? The present study used the computerized “mouse paradigm” assess near-instantaneous changes in affect over a short time. Dynamic indices were computed from approximately 1400 measurements last 2.5 minutes 3-minute assessment. Subjects monitored and reported emotional states by moving cursor along dimension “Sadder” “Happier.” They also completed self-report measures: Scales 2 (Depression) 9 (Mania) MMPI-2, Positive Negative Affect Scale, Wisconsin scales Physical Anhedonia Hypomanic traits. instantaneous data yielded summary measure mean affect, as well variability. Complexity derived examined. Mean ratings correlated expected directions with paper pencil measures. There was evidence for low-dimensional chaos short-term dynamics. As hypothesized, greater complexity associated Pleasant Hypomania but negatively Anhedonia.
