“…Fatigue effects are based on the idea that subjective difficulty should be enhanced to the degree that relevant performance resources are depleted (Nolte et al, 2008;Wright et al, 2008). However, as outlined above, the effect of achievement motivation on mobilization of mental effort was probably not modulated by subjective difficulty.…”

“…We also asked about the importance of success (How important to you is it to meet the standard?, 1 = not at all important , 7 = very important ). Finally, as in Nolte, Wright, Turner, and Contrada (2008), we asked about perceptions of challenge and threat (“Does the D2 task seem challenging?” and “Does the D2 task seem threatening?”); both items had a 7-point format (1 = no, not at all , 7 = yes, definitely ).…”

Using motivational intensity theory as a framework, the present experiment examined how individual differences in self-focused attention interact with task difficulty to predict effort, assessed via cardiovascular reactivity. Participants (n = 50) worked on a cognitive task fixed at an easy, medium, or hard level of difficulty, and individual differences in private self-consciousness and self-reflection were measured. Regression models indicated that trait self-focus interacted with task difficulty to predict cardiovascular reactivity, particularly systolic blood pressure (SBP) reactivity. Participants low and high in trait self-focus showed similar SBP reactivity in the easy and medium conditions, but they diverged in the hard condition: High trait focus was associated with higher SBP reactivity, indicating greater effort, whereas low trait self-focus was associated with low SBP reactivity, indicating disengagement. The findings thus support the motivational intensity approach to effort and its interpretation of self-focus's role in effort mobilization. Keywords effort; cardiovascular reactivity; self-focused attention; private self-consciousness; motivational intensity Self-focused attention is a major construct in the psychology of self-regulation and motivation (Carver, 2003). A large literature shows that directing attention to the self causes people to compare themselves to relevant standards. When people feel able to meet a standard, high self-focus increases their motivation to do so, as seen in a variety of affective, cognitive, and behavioral outcomes (for reviews, see Carver & Scheier, 1998;. In the present research, we build upon recent applications of motivational intensity theory (Brehm, Wright, Solomon, Silka, & Greenberg, 1983;Wright, 1996) to selffocused attention. This theory makes new predictions about how self-focus affects the intensity of effort, measured with physiological outcomes. In particular, we examine how individual differences in trait self-focused attention and task difficulty jointly determine effort-related cardiovascular reactivity in an active coping situation.

“…To date, only one study in this research program has examined fatigue as a naturally-occurring -measured -variable, rather than as a manipulated variable (Nolte et al, 2008). It did so with the aim of documenting the external validity of earlier experimental fatigue findings, that is, their indication of what can occur in real world settings in which fatigue is induced spontaneously.…”
