Selective
Memorization as a Function of Intensity of Voice Presenting Items
I. Watanabe |
Two
selective free recall experiments were carried out as a function
of the intensity of a voice presenting the items, in order to examine
the effects of the physical characteristics upon selective memorization.
The percentage of correct recalls was greater and the number of intrusion-errors
was smaller in the weak intensity condition than in the strong intensity
condition in the rear section of serial positions. The effect of
intensity was not clear in the initial and middle sections. The results
suggest that the intensity affects the first selection which takes
place before short-term memory, but not the second one which takes
place in the process of transforming the to-be-memorized items into
long-term memory, which reflects the difference in the ways how these
selective processes work upon the items. It was also suggested that
such effects were produced by the intensity of the item relative
to that of the adjacent items.
