Abstract
Recent studies of Working Memory Capacity(WMC) indicate that High-Span Subjects(HSS) are superior to Low-Span Subjects(LSS) in controlling the Cognitive Functions of attention and language. Colflesh and his colleagues (2007) state in their Dichotic Listening study that HSS are superior in Attention Control over auditory information. However, the relation between WMC and Auditory Semantic Processing Capacity(ASPC) has not been clarified. By using the meaningful and meaningless syllables, this study examines the relation in between WMC, Attention Control and ASPC in DLT. As a result, the Reaction Time(RT) to the target word among the meaningless syllables in HSS is significantly rapid compared with the RT in LSS and also the RT in HSS is significantly more rapid to the meaningless syllables than to the meaningful syllables. This result confirms the previous studies of the superiority of HSS in Cognitive Functions control and suggests the intimate relation between the individual differences in WMC and ASPC.
