More dreams of the rarebit fiend: food sensitivity and dietary correlates of sleep and dreaming.

Background: Despite centuries-old beliefs and anecdotal evidence that food can influence one's sleep and dreams-an example being the classic d cartoon series-the topic has only rarely been researched.

Methods: We asked 1,082 participants to complete an online survey to test specific hypotheses on why people perceive that food affects their dreams, including whether specific foods influence dreams directly (food-specific effects), through physiological symptoms (food distress), or via altered sleep quality (sleep effects). Survey measures included standard demographic variables, targeted probes about self-perceived effects of specific foods on dreams, questions about diet, food intolerances and allergies, personality questionnaires, measures of sleep quality (Pittsburgh Sleep Quality Index) and the Nightmare Disorder Index.

Probabilistic refunds increase beverage container recycling behaviour in British Columbia and Alberta, Canada.

Of the two trillion beverage containers produced globally every year, most are not recycled. To increase recycling rates, the bottle deposit refund system has been proposed and implemented in some regions of the world with varying degrees of success. To improve the refund system, we leverage a classic decision-making phenomenon where low-probability high rewards are preferred over small certain rewards with the same expected payoff.

Unbreakable Resolutions as an Effective Tactic for Self-Control: Lessons From Mahatma Gandhi and a 19th-Century Prussian Prince.

Despite the relative consensus in the self-management literature that personal resolutions are not an effective stand-alone tactic for self-control, some individuals seem capable of using them to exert a remarkable level of control over their behavior. One such individual was Mahatma Gandhi, the famous Indian statesman. Gandhi often used personal resolutions-or "vows"-to commit himself to a range of challenging behaviors, such as extreme diets, sexual abstinence, and fasting.
