Objectives Appraising health as controllable is typically thought to be adaptive, but recent evidence suggests the paradoxical possibility that perceived control (PC) can be detrimental. We considered the premise that high PC should have a survival benefit when it is part of an adaptive mindset involving high value (importance) for health, but it might be detrimental when it is part of a mindset comprised of low health value (HV). In addition, we examined whether the survival consequences of PC and HV vary with advancing age. Method Interviews were conducted with a heterogeneous sample of community-dwelling adults (n = 341; 72–99 years) to assess appraisals of control and value in the domain of health. Mortality data were obtained over 12 years from a provincial health registry. Results Both age and HV moderated the PC effect on mortality. The predicted beneficial and detrimental PC effects emerged at younger ages: higher PC predicted longer survival times when health was highly valued but shorter survival times when health was less highly valued. Discussion These findings deepen the knowledge regarding the conditions under which PC is or is not adaptive, suggesting the consequences depend on age and the extent to which health is valued.

When a visual stimulus is quickly followed in time by a second visual stimulus, we are normally unable to perceive it consciously. This study examined how affective states influence this temporal limit of conscious perception. Using a masked visual perception task, we found that the temporal threshold for access to consciousness is decreased in negative mood and increased in positive mood. To identify the brain mechanisms associated with this effect, we analysed brain oscillations. The mood-induced differences in perception performance were associated with differences in ongoing alpha power (around 10 Hz) before stimulus presentation. Additionally, after stimulus presentation, the better performance during negative mood was associated with enhanced global coordination of neuronal activity of theta oscillations (around 5 Hz). Thus, the effect of mood on the speed of conscious perception seems to depend on changes in oscillatory brain activity, rendering the cognitive system more or less sensitive to incoming stimuli.
