Using eye movement analysis to study auditory effects on visual memory recall.

Marandi RZ, Sabzpoushan SH - Basic Clin Neurosci (2014)

Bottom Line: The method was validated with eight different participants.Recognition rate in "with sound" stage was significantly reduced as compared with "without sound" stage.The result demonstrated that the familiarity of visual-auditory stimuli can be detected from EOG signals and the auditory input potentially improves the visual recall process.

ABSTRACT
Recent studies in affective computing are focused on sensing human cognitive context using biosignals. In this study, electrooculography (EOG) was utilized to investigate memory recall accessibility via eye movement patterns. 12 subjects were participated in our experiment wherein pictures from four categories were presented. Each category contained nine pictures of which three were presented twice and the rest were presented once only. Each picture presentation took five seconds with an adjoining three seconds interval. Similarly, this task was performed with new pictures together with related sounds. The task was free viewing and participants were not informed about the task's purpose. Using pattern recognition techniques, participants' EOG signals in response to repeated and non-repeated pictures were classified for with and without sound stages. The method was validated with eight different participants. Recognition rate in "with sound" stage was significantly reduced as compared with "without sound" stage. The result demonstrated that the familiarity of visual-auditory stimuli can be detected from EOG signals and the auditory input potentially improves the visual recall process.

Sample pictures of the four categories (abstract, landscape, face, and building) and their sequence of display used in the experiment. Each picture was shown for five seconds; black screen pictures were shown in between for three seconds as intervals.

Figure 0002: Sample pictures of the four categories (abstract, landscape, face, and building) and their sequence of display used in the experiment. Each picture was shown for five seconds; black screen pictures were shown in between for three seconds as intervals.

Mentions: The experiment was performed in two sections. In the first section participants were presented four categories of pictures including faces, landscapes, abstract images and buildings without sound (Fig. 2). Each category contained nine pictures. Six pictures of each category were presented once and the remaining three pictures were presented twice. The pictures were presented randomly. As shown in Fig. 2, each presentation took five seconds after which a black screen with a dot-shaped down- counter at the center was presented for three seconds. The second section of the experiment immediately followed the first part. The second part was similar to the first one while the pictures were different and soundmatched. Participant's task in this experiment was free viewing. They were not informed about the aim of the experiment.
