Abstract
The visual information that can't be detected by consciousness but can affect individual's behavior and attitude under specific conditions is called subliminal visual messages. In order to better apply subliminal visual messages to commercial advertising, education and other fields, this paper studied the process of subliminal visual messages in the brain. First, this paper designed a experiment to allow the subjects to see a series of pictures stimulation of different durations and collect the EEG signals, then analyzed the impact of stimulation time on classification accuracy. The experimental results showed that when the stimulus time is short, the classification accuracy increases with the increase of time, resulting in subliminal visual effects. However, with the increase of stimulus time, the classification accuracy began to decline. We speculated that the visual information changed from subthreshold to suprathreshold. The subliminal visual effects were disturbed until disappeared.
Highlights
The visual information that can't be detected by consciousness but can affect individual's behavior and attitude under specific conditions is called subliminal visual messages[1]
Convolution neural network is a kind of neural network which is used to deal with data with similar grid structure. it is widely used in computer vision, signal classification and other fields
The EEG signals collected at 40 ms, 60 ms, 80 ms, 100 ms, 120 ms, 200 ms and 500 ms were selected as the data set, and 10% of the data set was selected as the test set and the remaining 90% as the training set
Summary
The visual information that can't be detected by consciousness but can affect individual's behavior and attitude under specific conditions is called subliminal visual messages[1]. Previous studies on subliminal visual information mainly focused on visual subliminal persuasion and subliminal priming effect. Visual subliminal persuasion refers to the process in which subjects are stimulated by subliminal visual information and try to influence their views, attitudes or behaviors [2]. The research of visual subliminal persuasion is mainly focused on the influence of subliminal visual information on behavior.
