Content: Specifically, a positive mood may lead to more positive expectations concerning source trustworthiness or likability than a negative mood. As a consequence, people in a positive mood should be more surprised when they encounter an untrustworthy or dislikable source rather than a trustworthy or likable source. Negative mood
Like positive moods, negative moods have important implications for human mental and physical wellbeing. Moods are basic psychological states that can occur as a reaction to an event or can surface for no apparent external cause. Since there is no intentional object that causes the negative mood, it has no specific start and stop date. It can last for hours, days, weeks, or longer. Negative moods can manipulate how individuals interpret and translate the world around them, and can also direct their behavior. Negative moods can affect an individual's judgment and perception of objects and events. In a study done by Niedenthal and Setterland (1994), research showed that individuals are tuned to perceive things that are congruent with their current mood. Negative moods, mostly low-intense, can control how humans perceive emotion-congruent objects and events.
