汇编语言中存储器操作数的访问剖析

汇编语言是计算机软件系统中的基础学科，掌握《汇编语言程序设计》这一学科的难点之一。就是理解存储器操作数地址的形成。即每一个存储在内部存储器上的操作数都有唯一确定的地址(物理地址)，这个地址由两部分构成：段地址和段内偏移地址。段地址存放在段寄存器中。而偏移地址存放的位置比较灵活，形成了如直接寻址、间接寻址等多种寻址方式。从分析存储器操作数的存放地址入手。可以更好地理解寻址方式，准确访问存储器操作数。

“Blockers” do not block recall during tip-of-the-tongue states

Tip-of-the-Tongue experiences (TOTs) are often accompanied by incorrect answers (blockers) that come to mind persistently and seem to block recall. According to the blocking hypothesis, blockers cause retrieval difficulty during TOTs. We predicted that delay would allow participants to forget their blockers, and thereby enhance TOT resolution. In Experiment 1 participants were asked trivia questions and then retested on the ones that elicited TOTs, either immediately or after a delay. There was an incubation effect overall, with greater TOT resolution after a delay than on an immediate test. Contrary to the blocking hypothesis, however, delay did not enhance resolution of blocked TOTs more than non-blocked TOTs. In Experiment 2, during the retest, participants were reminded of their previous blockers on some questions, but the reminders did not affect TOT resolution. These findings suggest that blockers may be a side effect, not a cause, of retrieval difficulty during TOTs. This paper is based on the first author’s Master’s thesis.     

Reading ability and memory span: Long-term memory contributions to span for good and poor readers

A number of studies have shown that childrenwith reading difficulties perform poorly ontests of verbal memory span. The extent towhich differences in memory span for good andpoor readers can be explained by differences ina long-term memory component to span as well asby differences in short-term memory processeswas investigated in this study. Memory spanand rehearsal rate were measured for high andlow frequency words and nonwords. Althoughmemory span performance for high frequencywords was comparable for all reading abilitygroups, good readers had better memory spanperformance for low frequency words. This wasattributable to differences in both short-termand long-term memory contributions to spanperformance. Differences between readingability groups also emerged when memory spanfor nonwords was measured. In this case,differences between groups also appeared to bethe result of difficulties which poor readersencountered in learning newphonologically-based materials (i.e. nonwords). The nature of the inter-relationships betweenmemory span, reading and measures ofphonological awareness are discussed in thelight of these findings.
