Brain-mind states: reciprocal variation in thoughts and hallucinations

The exclusion of thinking from recent studies of sleep mentation has hindered a full appreciation of how cognitive activity differs across the states of waking and sleep. To overcome this limitation, this study investigated thoughts and hallucinations using experience sampling, home-based sleep-wake monitoring, and formal analyses of the psychological data. The prevalence of thoughts decreased gradually from waking through sleep onset and non-REM sleep, to reach its nadir in REM sleep, whereas hallucinations increased sharply across these states. Furthermore, multiple occurrences of hallucinations but not of thoughts increased significantly from sleep onset through non-REM sleep, to a peak in REM sleep. This reciprocity in thoughts and hallucinations might reflect a progressive shift from high to low aminergic-to-cholinergic neuromodulatory ratios across wake-sleep states, accompanied by an array of changes in the regional activation patterns of the brain.     

Effects of regulatory focus on endorsement of religious beliefs

Regulatory focus has an impact on different judgments. Specifically, promotion focus is directed at achieving positive outcome whereas prevention focus is directed at preventing negative outcomes. Thus, people in promotion focus endorse positive outcome-framed messages whereas people in prevention focus endorse negative outcome-framed messages. In two experiments, we examined whether this holds true for religious beliefs. In Experiment 1, participants were undergraduate students; we found the expected interaction between regulatory focus and verse frame. In Experiment 2, we replicated this finding with participants from conservative Lutheran communities, demonstrating that there was a transient influence of induced regulatory focus. This finding suggests that regulatory focus either is difficult to discount or is not a peripheral cue that is used in heuristic processing only, but an internal state that has a pervasive impact even if people are highly motivated to process information systematically.
