- Abstract
- The influence of pleasant odour exposure and positive feedback has been shown to improve cognitive task performance. Research has also shown that pleasant odours facilitate improvement in tasks through the elevation of mood (Gilbert, Knasko & Sabini, 1997). Pleasant odour exposure has also able to improve self-efficacy and self-esteem (Baron, 1990; Rho, Han, Kim & Lee, 2006). Previous research has indicated that positive feedback and successful performances will increase cognitive performance, self-efficacy, self-esteem and mood and negative feedback has the inverse effect (McFarlin & Blascovich, 1981; Shrauger & Rosenberg, 1970; Smith, Kass, Rotunda & Schneider, 2006). The impact of odour (pleasant, none) and false feedback (positive, negative, none) on task performance, self-esteem, general self-efficacy and mood was explored in a 2 x 3 experimental design (n.20 per condition). A group of 120 individuals aged 17 to 60 (50 males, 71 females) from a North London university and the general public. Participants completed two self-evaluations of general self-efficacy, self esteem and mood and performed a sentence-checking task twice. Participants received positive, negative or no feedback on their first task before completing the same questionnaire and cognitive test again whilst being exposed to a pleasant odour or no odour. Participants also rated the hedonic qualities of the odour. There were no significant main effects of odour or feedback or interaction effect of odour x feedback were found test performance, self-esteem, self-efficacy and mood. However, the regression model indicated that second test performance could be predicted by feedback, odour exposure and baseline and post-interventions scores of self-esteem, self-efficacy and mood.
