| Outline of Final Research Achievements |
For developing a new cognitive mental therapy for depression, the relationship between the human mood and the attentional performance was studied.
There is a growing evidence to suggest that mood may affect the capacity to perform low-level cognitive tasks. Therefore, we examined whether a perceived happiness level affects their ability to detect a target in noise that required attention. We employed pop-out and serial visual search paradigms, implemented using a novel smartphone application that allowed search times and self-rated levels of happiness to be recorded. Using our smartphone application, we were able to replicate the classic visual search findings, and find that serial search times with the maximum numbers of distractors were significantly faster for high happiness levels than low happiness levels. Our results show that monitoring/improving attentional performance could be used for predicting/changing happiness levels.
