| dc.description.abstract | This study aims to provide electrophysiological evidence that could explain how the various categories of moral identity influences the emotion-attentional bias towards smoking and non-smoking stimuli. This study has two phases. In phase 1, the Moral Identity Scale and the visual affective stimuli were validated in 388 youths (age range from 18 to 24) recruited from Kota Bharu, Kelantan. In phase 2, participants (N=78) underwent the Elecroencephalogram -EEG recording (ERP session) at the Neuroscience Laboratory. The validated images of smoking and non-smoking images were used as visual stimulus to evoke the participants’ emotional cognition that influence their attentional bias towards the different categories of images. Discriminant validity and the construct reliability of the two factors were looked into. Two-weeks interval test-retest Intraclass Correlation Coefficient (ICC) and the Split-half analysis was used. Convergent validity revealed that the valence and arousal and the visual affective stimuli has a high correlation. The ERP recording data indicates the early ERP components (P100, N100, P200, N200), showed significant interaction effect between the emotion-attentional bias of the visual affective stimuli with the moral identity categories in the latency of the P100, N100, N200 and P200 ERP component and only in the P200 among the amplitude early ERP components in the frontal and temporal brain region. Neuroscience provides a foundation for understanding the complex interplay between brain mechanisms, moral identity, and behaviours like smoking. | |
