Differences in Perceptual Reactivity According to the Nature of the Stimuli
Valentina-Elisabeta Constantin
Abstract
The objective of this research is to identify and compare the differences in perceptual reactivity depending on the stimuli to which the participants were subjected to the experiment. In this case, it is the auditory and visual stimuli. The hypotheses of this study are: 1. Perceptual reactivity is influenced by the auditory stimulus by recording a longer reaction time in the group to which this stimulus was applied compared to the control group. 2. Perceptual reactivity is influenced by the visual stimulus by recording a longer reaction time in the group to which this stimulus was applied compared to the control group. 3. Perceptual reactivity is more strongly influenced by the visual stimulus than by the auditory one. Procedure - we used the "Associative-verbal" test which contains 15 words of which 4 are reactive words (found in auditory and visual stimuli), 4 words are similar to the reactive ones, and 7 words are neutral. Participants were asked to associate each word with another representative of the basic one. Reaction time and unusual behavioral changes were recorded in a table. Participants were divided into 3 groups: control group, group to which an auditory stimulus was applied, group to which a visual stimulus was applied. The hypotheses were confirmed; there were statistically significant differences between perceptual reactivity to the auditory stimulus and perceptual reactivity to the visual stimulus.
