Mortality salience, effort, and cardiovascular response to a bar-press challenge: Remarkably nuanced effects of a death prime on heart performance

We presented participants with a bar-pressing challenge relevant to their identity after having exposed them to a prime that made their mortality more or less salient. For some participants, difficulty was low; for others, it was high; for the rest, it was unfixed. As expected, heart pre-ejection period responses-reflecting heart contraction force-were (a) stronger under high-salience conditions when difficulty was high and unfixed, but (b) low regardless of salience when difficulty was low. Findings bear out conceptually and extend results from a previous experiment. In doing so, they add substantively to a new line of support for terror management theory and document the predictive utility of a proposed blended analysis of associated effort processes. The blended analysis speaks to the way in which motives to manage existential terror should convert into active goal striving and to the impact that existential threat might have on aspects of autonomic arousal.

Understanding Psychological Reactance: New Developments and Findings

Since Brehm first proposed reactance theory in 1966, many studies have explored the remarkable psychological phenomenon of reactance, which Miron and Brehm reviewed in 2006. We present an overview of research that has been done since then. A variety of studies have provided interesting new insights into the theory, adding to what is known about the phenomenon of reactance and the processes activated when people are confronted with threats to their freedom. Nevertheless, many issues that have not been clarified remain to be examined. We therefore close with proposing some suggestions for future research.
