overlap_circle: Interpolate the Inclusion of the Other in the Self Scale

In RemPsyc/rempsyc: Convenience Functions for Psychology

Interpolate the Inclusion of the Other in the Self Scale

Description

Interpolating the Inclusion of the Other in the Self Scale (IOS; self-other merging) easily. The user provides the IOS score, from 1 to 7, and the function will provide a percentage of actual area overlap between the two circles (i.e., not linear overlap), so it is possible to say, e.g., that experimental group 1 had an average overlap of X% with the other person, whereas experimental group 2 had an average overlap of X% with the other person.

Usage

overlap_circle(response, categories = c("Self", "Other"), scoring = "IOS")

Arguments

response	The variable to plot: requires IOS scores ranging from 1 to 7 (when scoring = "IOS").
categories	The desired category names of the two overlapping circles for display on the plot.
scoring	One of c("IOS", "percentage", "direct"). If scoring = "IOS", response needs to be a value between 1 to 7. If set to "percentage" or "direct", responses need to be between 0 and 100. If set to "direct", must provide exactly three values that represent the area from the first circle, the middle overlapping area, and area from the second circle.

Details

The circles are generated through the VennDiagram::draw.pairwise.venn() function and the desired percentage overlap is passed to its cross.area argument ("The size of the intersection between the sets"). The percentage overlap values are interpolated from this reference grid: Score of 1 = 0%, 2 = 10%, 3 = 20%, 4 = 30%, 5 = 55%, 6 = 65%, 7 = 85%.

Value

A plot of class gList, displaying overlapping circles relative to the selected score.

For a javascript web plugin of a continuous version of the Inclusion of Other in the Self (IOS) task (instead of the pen and paper version), for experiments during data collection, rather than data analysis, please see: https://github.com/jspsych/jspsych-contrib/tree/main/packages/plugin-ios

Examples

# Score of 1 (0% overlap)
overlap_circle(1)

# Score of 3.5 (25% overlap)
overlap_circle(3.5)

# Score of 6.84 (81.8% overlap)
overlap_circle(6.84)

# Changing labels
overlap_circle(3.12, categories = c("Humans", "Animals"))


# Saving to file (PDF or PNG)
plot <- overlap_circle(3.5)
ggplot2::ggsave(plot,
  file = tempfile(fileext = ".pdf"), width = 7,
  height = 7, unit = "in", dpi = 300
)
# Change for your own desired path
