Although it is difficult to measure the e-commerce economy precisely, its size is estimated to be relatively small (some $26 billion United States) at present, but it is expected to grow very rapidly and approach $1 trillion by 2005. E-banking represents a significant share of the overall e-commerce activities. Five strategic and tactical reasons exist for banks to invest in e-commerce. The first one is cost reduction in transactions between bank and customer. Second, the image of the bank can be promoted and visibly increased globally. Third, new services can be introduced, either standalone or as added features to existing products. Fourth, market expansion and reach is increased. Recent changes in the regulatory framework have enabled many banks to expand their services into non-traditional banking areas. For instance, many banks have already moved into or are in the process of moving into insurance and stock brokerage. Finally, communication costs through online transactions and global information distribution are lowered (Dannesnberg & Kellner, 1998; Quelch & Klein, 1996; Prescott & Van Slyke, 1997; Mandeville, 1998). Traditionally, banks use the branch system and mass marketing techniques. Due to the emergence of new technologies and increased competition, banks need to develop one-to-one relationships with their customers and to improve the quality of their services. This, however, can only be possible if they can organise and establish their own Internet-based Virtual Communities (VCs).

The visual environment consists of global structures (e.g., a forest) made up of local parts (e.g., trees). When compound stimuli are presented (e.g., large global letters composed of arrangements of small local letters), the global unattended information slows responses to local targets. Using a negative priming paradigm, we investigated whether inhibition is required to process hierarchical stimuli when information at the local level is in conflict with the one at the global level. The results show that when local and global information is in conflict, global information must be inhibited to process local information, but that the reverse is not true. This finding has potential direct implications for brain models of visual recognition, by suggesting that when local information is conflicting with global information, inhibitory control reduces feedback activity from global information (e.g., inhibits the forest) which allows the visual system to process local information (e.g., to focus attention on a particular tree).
