DATA & FILE OVERVIEW
--------------------

This dataset contains:

The dataset includes data for each participant for all four experiments in the paper (all N = 35).
Responses (all experiments) were coded 1 (left stimulus perceived larger) / 2 (right stimulus perceived larger). 
Conditions (size, shape, orientation combinations) were coded as follows:

Size (area): 1 to 4, corresponding to 5, 6.67, 8.33, 10 cm2 across all experiments. 

Orientation: (Experiment 3 and 4 only): 1 to 3, corresponding to: 1) Canonical, 2) Longer linear length vertical, 3) Longer edge horizontal (Experiment 4 only).
Shape: different codes in each experiment


Experiment 1:
1.	Disk
2.	Triangle 
3.	Square
4.	1:8 rectangle 
5.	H-shape 
6.	8-point star 


Experiment 2:
1.	Disk
2.	Triangle
3.	Square
4.	Octagon
5.	V-shape 
6.	H-shape 
7.	X-shape 
8.	3-point star 
9.	4-point star 
10.	8-point star 


Experiment 3: 
1.	Disk
2.	Triangle
3.	Square
4.	Octagon 
	Experiment 4: 
1.	Square
2.	1:2 rectangle 
3.	1:4 rectangle
4.	1:8 rectangle
