Although studies have identified a link between employee intrinsic motivation (IM) and creativity and between positive mood and creativity, some of this study has been equivocal and little research has included these variables in an integrative model. Drawing from several theories of IM, we address this gap by proposing that IM is a critical intervening mechanism in the relationship between positive mood and creativity, and team knowledge sharing affects the power of this mechanism. Research on field data from 120 R&D team members in 30 teams found that team-level knowledge sharing moderated the relationship between employees' positive mood and IM, and IM mediated the relationship between employees' positive mood and their creativity. Implications of our findings are discussed.

The aime of the present study was to examine and compare happiness in athletic and non-athletic women.120 female university students (athletes and 60 non-athletes)were randomly assigned to two groups and Oxford happiness Inventory (reliability and validity have been shown in Iran)was used.The results showed that athletic women were in higher level at the five scales (mental health,self-steem,efficiency,satisfaction and positive mood).Also,there was a significant difference between level of happiness in two groups

Even though ageing is associated with declining cognitive capabilities, research has demonstrated an age-related improvement in affective well-being. This improvement can be related to increased resilience, developing as changes in emotion regulation at information-processing level. During negative mood, emotion regulation becomes a priority as demonstrated by an increased preference for positive over negative information in older adults. However, the effect of a positive mood on older adult’s attentional preferences has not been established yet. To investigate this, 37 older adults were randomly assigned to a relaxation or a control condition (music). Mood state was assessed before and after the manipulation. Attentional bias was measured by an exogenous cueing task, in which the location of the target was correctly or incorrectly cued by happy, sad or neutral facial pictures. Both groups showed a decrease in negative mood (p < .001, 95% CI [2.73, 5.97], d = .82) without changes in positive mood. The relaxation group showed a significantly bigger increase in feeling relaxed (p = .017, η2p = .15). No significant group differences were found for attentional bias. However, over the whole group, less positive mood after the manipulation was associated with more maintained attention for positive information (r = –.49, p < .01). These results indicate that older adults deploy emotion regulation strategies in attention during low positive mood. Flexible attentional processing of emotional information might serve as a resilience factor to maintain well-being during later stages of life.
