stimulus used to test animals
repeat
0 only one measurement per individual, 1 repeated measures for each individual
number
number of repeat, for example: stage 1 to 8 within the same experiment
criterion
learning criterion used
sex
male or female

order a species belongs to
age
age-class of subjects
data source
source of raw data, either from a publication or raw data file provided by authors or online repository
sample size
number of individuals that reached the learning criterion
