COMPARING DISTRIBUTIONS

The analyses were conducted using RSTUDIO

Comparing ocular reaction times, when presented with few targets (two) or with many targets (six).

At the top are two examples of possible distributions that could be found. Its easy to see where they differ by looking at the red circle: the first graph has overlapping distributions at the bottom part while the second presents equally spaced distributions. The third graphs, under Results, shows what was actually found in our data: we found that the ocular distributions in the two conditions were equally spaced at the bottom, therefore confirming the parallel distribution scenario.

These analyses were written up into a scientific article and published in an International Journal: Experimental Brain Research

COMPARING PSYCHOMETRIC FUNCTIONS

The analyses were conducted using MATLAB

Examining an example of performance at 70% for three participants. Participants had to use their attention to determine whether a stimulus flashed incredibly briefly (20 milliseconds) had was oblique to the right or the right (stimulus DT presented in the magnifying glass; its oblique to the right). A larger angle, meaning the DT stimulus would be more oblique, made it easier to see. We see that the blue function shows a participant that needed a smaller angle to have a good performance at 70%, while the green function shows a participant who needed a much larger angle (i.e. much easier to see) in order to have the same good performance at 70% correct. 

These analyses were written up into a scientific article that was pre-printed on Biorxiv.org, and will be subsequently in 2019.
