Abstract:The goal of this study was to examine the influence of motivation on attention and conscious visual perception. Motivation was manipulated by the possibility of a monetary reward that depended on performance. To examine attention and conscious visual perception a combination of a Posner cueing paradigm with backward masking was used. In total 23 participants participated. Electroencephalogram (EEG) measurements were used to examine attention by α-activity. Lateralized power spectra (LPS) were used to analyse the EEG measurements by comparing α-activity for the ipsilateral and contralateral hemispheres. It was expected that participants in the motivation group would perform better than participants in the control group due to a better allocation of attention. Analysis of the data showed that extrinsic motivation did not have a positive influence on conscious visual perception. Analysis of the EEG measurements showed that participants actively directed their attention, but extrinsic motivation did not have an influence on endogenous attention. A recommendation for future research could be to increase self-efficacy of participants by enabling more participants to win money.
