Stimulus similarity modulates sensory dominance effects in cross-modal conflicts

Experiment 1:(1) Experiment 1 data is divided into three subfolders based on stimulus similarity, where d represents dissimilarity, ps represents auditory similarity, and vs represents visual similarity.(2) Each subfolders contains raw data files (in CSV format) for 35 subjects, as well as a script file for data batch processing (in. m format).(3) Each participant's CSV format data consists of 10 columns. The first column, trialID, is the trial ID, the second column, PicType, is the image type (a total of four images, from 1 to 4), the third column, SoundType, is the sound type (a total of four voices, from 1 to 4), the fourth column, Correspondence, is the consistency type of the audio-visual channel (1 represents consistency, 2 represents inconsistency before reaction, and 3 represents inconsistency in reaction), the fifth column, Block, is the attention type (1 represents attention to visual, 2 represents attention to auditory), the sixth column, DataBlock (1 represents attention to visual data, 2 represents attention to auditory data), and the seventh column, RT (the average reaction time of key presses). The eighth column is the response (which requires a reaction and is divided into 1 and 2), and the ninth column is the correct response (the key press response of the subject), The tenth column hit represents the reaction type (1 for correct reaction, 0 for incorrect reaction).(4) Focus on the fourth column (consistency vs. pre reaction inconsistency vs. reaction inconsistency in the distinguishable independent variable audio-visual channel consistency), fifth column (attention visual channel vs. attention auditory channel in the distinguishable independent variable attention channel), seventh column (dependent variable reaction time), and tenth column (accuracy)(5) Because Experiment 1 includes a total of 18 experimental conditions, each with 48 trials. Under the conditions of dissimilarity, auditory similarity, and visual similarity, there are six conditions: attentional visual consistency, attentional visual pre reaction inconsistency, attentional visual response inconsistency, attentional auditory consistency, attentional auditory pre reaction inconsistency, and attentional auditory response inconsistency.Experiment 2a:(1) The data from Experiment 2a is divided into three subfolders based on stimulus similarity, with anodal representing positive stimuli, cathodal representing negative stimuli, and sham representing pseudo stimuli. The data from Experiment 2b is the same as the content of Experiment 2a(2) In Experiment 2a, each sub folder contains raw data files (in CSV format) for 26 subjects, as well as a script file for data batch processing (in. m format).(3) Each participant's CSV format data consists of 10 columns. The first column, trialID, is the trial ID, the second column, PicType, is the image type (a total of four images, from 1 to 4), the third column, SoundType, is the sound type (a total of four voices, from 1 to 4), the fourth column, Correspondence, is the consistency type of the audio-visual channel (1 represents consistency, 2 represents inconsistency before reaction, and 3 represents inconsistency in reaction), the fifth column, Block, is the attention type (1 represents attention to visual, 2 represents attention to auditory), the sixth column, DataBlock (1 represents attention to visual data, 2 represents attention to auditory data), and the seventh column, RT (the average reaction time of key presses). The eighth column is the response (which requires a reaction and is divided into 1 and 2), and the ninth column is the correct response (the key press response of the subject), The tenth column hit represents the reaction type (1 for correct reaction, 0 for incorrect reaction).(4) Focus on the fourth column (consistency vs. pre reaction inconsistency vs. reaction inconsistency in the distinguishable independent variable audio-visual channel consistency), fifth column (attention visual channel vs. attention auditory channel in the distinguishable independent variable attention channel), seventh column (dependent variable reaction time), and tenth column (accuracy)(5) Because Experiment 2a includes a total of 18 experimental conditions, each with 48 trials. Under the conditions of negative stimulation, positive stimulation, and pseudo stimulation, there are six conditions including attentional visual consistency, attentional visual pre response inconsistency, attentional visual response inconsistency, attentional auditory consistency, attentional auditory pre response inconsistency, and attentional auditory response inconsistency, respectively.Experiment 2b:(1) The data from Experiment 2b is divided into three subfolders based on stimulus similarity: anodal represents positive stimuli, cathodal represents negative stimuli, and sham represents pseudo stimuli. The content of Experiment 2b data is the same as that of Experiment 2a(2) In Experiment 2b, each sub folder contains raw data files (in CSV format) for 24 subjects, as well as a script file for data batch processing (in. m format).(3) Each participant's CSV format data consists of 10 columns. The first column, trialID, is the trial ID, the second column, PicType, is the image type (a total of four images, from 1 to 4), the third column, SoundType, is the sound type (a total of four voices, from 1 to 4), the fourth column, Correspondence, is the consistency type of the audio-visual channel (1 represents consistency, 2 represents inconsistency before reaction, and 3 represents inconsistency in reaction), the fifth column, Block, is the attention type (1 represents attention to visual, 2 represents attention to auditory), the sixth column, DataBlock (1 represents attention to visual data, 2 represents attention to auditory data), and the seventh column, RT (the average reaction time of key presses).

Under the conditions of negative stimulation, positive stimulation, and pseudo stimulation, there are six conditions including attentional visual consistency, attentional visual pre response inconsistency, attentional visual response inconsistency, attentional auditory consistency, attentional auditory pre response inconsistency, and attentional auditory response inconsistency, respectively.Script analysis:The data analysis part first removes standard deviations based on MATLAB programs, and then analyzes using R language. In data preprocessing, (1) all subjects' data are first proposed to exclude trials with reaction times greater than 2500 or less than 100ms; (2) Then, under each condition, exclude data outside the mean ± 3 standard deviations.
