Autonomic specificity in emotion: The induction method matters.

Research on the autonomic specificity of emotion has spanned decades, yet the findings of this research are still highly debated. Although many studies have explored the autonomic specificity of emotions, few have concurrently explored the influence by which the induction methods themselves have had in directing autonomic change. The current study was conducted to assess whether the methods for emotion elicitation could be meaningfully captured by multivariate pattern classification techniques that have been previously used to explore autonomic specificity of emotion. This aim was achieved by using three separate emotion-elicitation methods to elicit five separate emotions. A sample of 64 college-aged students watched film clips, read imagery scripts, and recalled personal memories for five emotion states. Using multivariate pattern classification analysis, the evidence from the current study lends further support for autonomic specificity of emotion, but also highlights the role that the specific induction technique contributes to autonomic changes that accompany emotions in the laboratory.
