The Relationship And Structure Of Attention, Working Memory, Speed Of Information Processing And Intelligence

In recent years, the research of intelligence is more and more close to the cognition field. Researchers think intelligence reflects the whole cognition level in the people, but there are some different conclusions of the cognition structure of intelligence. Based on some researches, firstly, using MULTIREGRESSION to analyze the influence of sustained attention and selective attention to working memory. Then, using structure equation models to discuss the relationship and structure of attention, working memory, speed of information processing and intelligence. These researches indicate that:1. Sustained attention and selective attention play different roles in the mechanism of working memory. Sustained attention is the core of central executive in working memory, so sustained attention is the cognition core of attention in information processing.2. Working memory has a significant positive forecast to intelligence and has a high relationship with the intelligence, but their structure and mechanism are different.3. In the information processing, the selective reaction forecasts intelligence better than simple reaction. The forecast of simple reaction is not significant, but the selective reaction has a distinctly significant negative forecast to intelligence.4. Attention, working memory, speed of information processing all has direct influence to the intelligence, but the stations and effects are different. The base factor is attention; it forecasts intelligence through working memory and speed of information processing. The biggest forecast is working memory to intelligence, the second one is attention to intelligence, and the last one is speed of information processing to intelligence. Attention, working memory, speed of information processing can work together to forecast about four-fifths of intelligence.5. The forecast of attention, working memory, speed of information processing to intelligence is higher than attention-working memory to intelligence or than attention-speed of information processing to intelligence.
