1. Figure Code

This folder contains the Matlab codes to create the figure pannels.

1.1 figure 05d : Seven representative shapes used in MDS plots when refering to global scale alone.

1.2 subfunctions : Dependent matlab subfunctions to used by the each of the figure panel codes.

figure_XX : Matlab code (.m file) to generate each figure panel of the manuscript.

L2_XX : There is an L2_xx.mat corresponding to each experiment (L2_SD.mat-exp01, LSmain.mat-exp02, L2_GLIE.mat-exp03, L2_IEpossizenum.mat-exp04, L2_pos2.mat-exp05 and L2_IE_grouping.mat-exp06). This data stucture is formed by pooling the data from all the participants of the experiment.

2. Stats

This folder contains the R codes used find the statistical significance.

2.1 Exp01_BlockwiseSameDifferent_HierarchicalShapes : All files used to report stats based on experiment-1

2.2 Exp02_VisualSearch_HierarchicalShapes : All files used to report stats based on experiment-2

multiscale_stats_summary.xlsx : Summary of all the Linear Mixed model reported in the manuscripts.

Exp01_BlockwiseSameDifferent_HierarchicalShapes

2.1 Exp01_BlockwiseSameDifferent_HierarchicalShapes

FIG_XX.R : R codes to check the statistical significance of the effect. There is a separate code for each subpanel.

FIG_SX.pdf : R generated pdf files for supplimentary figure-1

GDLD_Global_Advantage_LMMoutputs.txt : Linear Mixed Model model output for GDLD pairs with blocks and image pairs as fixed factors and Subjects as random factor.

SAME_DIFFERENT_EXP.csv : Exp-01 data in csv format. All the R analysis is based on this csv file.

create_data_csv_EXP_01_SD.m : Matlab code to generate the csv file from the L2_SD.mat (Consolidated experimental data of Exp-01)

2.2 Exp02_VisualSearch_HierarchicalShapes

FigurXX.R : Rcodes to check the statistical significance of the effects in exp02. There are separate codes for each panel.

GL_VS.csv : Exp 01 data in csv format.

VS_distractor_congruence.csv : Estimated target congruence RT data for doing the stats on Figure 4G top panel.

VS_target_congruence.csv : Estimated distractor congruence RT data for doing the stats on Figure 4G bottom panel.
