Background: Depressed patients are advised by clinicians to avoid making critical life decisions because their decision-making process might be influenced by their pathological mood states. In order to provide empirical support for this practice, we examined the influence of different mood states on risk-taking tendencies that govern one’s decision during critical life decisions. Method: By mea...

Behavioral economics tells us that emotions can profoundly affect individual behavior and decisionmaking. Does this also apply to societies at large, i.e. can societies experiencemood states that affect their collective decision making? By extension is the public mood correlated or even predictive of economic indicators? Here we investigate whether measurements of collective mood states derived...

Research to intraday fluctuations of mood in healthy subjects has indicated that diurnal patterns occur in positive mood states such as vigour, happiness and hedonic tone as well as in negative mood states such as fatigue, depression and anxiety (14). Yet, no clear statements can be made about how mood states are related to time of the day, because conflicting findings have been reported about ...

Lane and Terry (2000) defined mood as “a set of feelings, ephemeral in nature, varying in intensity and duration, and usually involving more than one emotion” (p.16). They proposed a conceptual framework for predicting performance from mood states assessed by the Profile of Mood States (McNair, Lorr, & Droppleman, 1971) or its derivatives. The conceptual model indicated that depressed mood infl...

Acute mood changes occur with various forms of physical activity. Increased levels of endogenous opioids (endorphins) in response to exercise may mediate activity-induced shifts in mood state. Thirteen female and six male aerobics class participants aged 20-46 years received the opiate receptor antagonist naltrexone and a placebo in randomized, double-blind crossover fashion on two separate occ...
