Abstract

The current study examined the notion that the effect that differences between serial recall of stimuli presented in different sensory modalities. Therefore, it was hypothesized that, people who apply visual presentation as images of words recall better than people who apply auditory presentation as a record. In addition to that, people who apply both visual and auditory presentation at the same time recall better than only auditory or only visual presentation does. A sample of 24 undergraduate students was used to test this hypothesis by applying visual, auditory and both visual and auditory presentation. It was found that people who apply visual presentation recalled significantly more words than people who applied auditory presentation, F (23) = 16.592, p<.05. Moreover, people who applied both of presentation (visual –auditory) recalled significantly, more words than people who applied only auditory presentation. Limitations of the study and recommendations for further research were discussed.

The effects of modality differences on short term memory

The modality effect means that number of differences between immediate serial recall of stimuli presented in different sensory modalities such as visually or auditory (Beaman, 2002).
To understand how auditory and visual information are encoded in short-term memory it is essential to look at the phonological loop and the visuo-spatical sketch pad (Ashcraft and
Radvansky, 2010).

The phonological loop is the speech- and sound- related component responsible for rehearsal of verbal information and phonological processing. There are two components of
