Information processing- processing speed
Intelligence is not down to `g' or PMA's but down to how quick you can process
information. All types of intelligence are influenced by how quickly you process
them such as working quickly and methodically or quickly learning a routine.
Fry and Hale found that half of the increase in fluid intelligence for children
aged 7 to 19 was due to improvements in processing speed and working memory. It
was also found that there is a general factor that affects both `g' and processing
speed. This shows that processing speed contributes towards fluid intelligence
although it may not be the cause of `g'.
/ Another study suggested that the decline in mental abilities that occur with
old age are caused by a decrease in processing speed. This shows that processing
speed is linked to old age. However the evidence is only correlational so it might
be that the decline of other abilities could be the cause of the decrease in
processing speed. Therefore processing speed may not be the ultimate cause of
Another study said there is a debate over the link between processing speed
and IQ. The theory suggests that high processing speed is the direct cause of
academic performance, yet this is not supported by evidence from a German study
that found processing speed had little direct impact on school performance. It did
influence creativity which suggests processing speed has an indirect link. This
means that the relationship between processing speed and intelligence is unclear.
