Explicit memory errors may occur when individuals fail to retrieve information about items previously studied (item memory) or about the learning context (source memory). We examined electrophysiological measures during recognition failure in order to determine the influence of retrieval orientation for item versus source information. Recognition failure was associated with brain potentials distinct from those associated with success. Furthermore, source-memory failures were associated with earlier-onset brain potentials with a more anterior distribution compared to item-memory failures. Neurocognitive processing was thus modulated by retrieval orientation so as to differentially influence neural correlates of successful versus unsuccessful retrieval.
只要我们综观各个时期的各类词典,不难看出,编纂者们对“than”这个词处理得都十分审慎。早期的词典都把它单一地划为连接词,而对它的其它用法却讳莫如深。有的词典只承认它在“than whom"结构中才是介词。如:These workers,than whom I have never seen men more industrious,have left me。也有的词书把它视为准介词(quasipreposition)。
