Three experiments are planned to be carried out employing the perceived control-stress pardigm, all them aimed at: Analyzing the dual effect of perceived control (sense of control vs. effort to control) on cardiovascular reactivity. Relationship between self-efficacy and cardiovascular reactivity would be examinated in order to determine if it's better fitted to a quadratic than to a linear regression model. - Identifying the autonomic mechanisms that mediate such relationship, in order to explain the specificity of regulation for each psychophysiological response. - Evaluating if the effects of perceived control on psychophysiological reactivity under different behaviour-outcomes contingencies (reinforcement vs. punishment) are analogous. Consequently, determine the moderator effect of sensitivity to punishment and to reward as dispositional constructs on appetitive and aversive motivational systems. - Assessing the moderator role of sensitivity to punishment and sensitivity to reward, and analyzing their impact on physiological reactivity, anxiety and coping. - Extending the analysis of the relationship perceived control-psychophysiological reactivity to variables more directly related to health status: immunoglobulin A and cortisol.
