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. For example, Niedenthal and Setterland used music to induce positive and negative moods. Sad music was used as a stimulus to induce negative moods, and participants labeled other things as negative. This proves that people's current moods tend to affect their judgments and perceptions. These negative moods may lead to problems in social relationships. For example, one maladaptive negative mood regulation is an overactive strategy in which individuals over dramatize their negative feelings in order to provoke support and feedback from others and to guarantee their availability.
