Long term memory has been modeled based on two different types of memory; declarative and non-declarative. Previous studies suggested that declarative memory was associated with high level of emotional arousal. In contrast, non-declarative memory was not. Based on this hypothesis, this paper investigated memory effectiveness using the EEG-based emotional arousal. In the experiment, word recognition test was used as a declarative memory test and word stem completion test as a non-declarative memory test. Four students from IIUM participated in the experiment and their brain signals were recorded to extract EEG-based emotional arousal during the memory tests. The findings from this research showed interesting correlation of the explicit and implicit memory effectiveness. The findings of this research were found to be consistent with suggestions of previous neuroscience and psychology studies, and provided new evidence in analyzing memory effectiveness with emotional arousal.
