In this study, we tested 8 Sleepy-lizards (Tiliqua rugosa asper) on their
ability to spontaneously choose the larger of two quantities based on
continuous or discrete information. We recorded the lizards'
identity, weight (g) and snout-vent length (mm). As we tested lizards in
two batches (groups), we also recorded if they belonged to group A or B.
In regards to the experiment, we recorded session (day), trial (1-12),
stage (preference test or quantity discrimination), date of the test day
and start time of the first trial, the test (continuous or discrete) and
the comparison. We measured lizards' choice behaviour by recording
the choice of the quantity as well as a binary version that represented
the choice of the larger quantity as 1 and the smaller choice as 0.
Finally, we also quantified the time it took lizards to make a choice from
trial videos in seconds (latency). NA values indicate either no data or no
choice. We analysed the choice behaviour using the binary choice data and
also the latency to understand if lizards were able to discriminate
quantities and if they showed a speed-accuracy trade-off. We provide
trial-by-trial raw data in a horizontal format. How to transpose the data
set into a vertical format and details regarding further calculations and
statistical analyses can be found on OSF, doi: 10.17605/OSF.IO/PR46D
