Need to remember: Dolphins recall their own actions after long delays

The R code and data needed to replicate results from the article:

Need to remember: Dolphins recall their own actions after long delays

Abstract

NOTE: Some large model files are not available in this repository. They can be downloaded from Zenodo after publication. That repository also contains all code, so replicating results is easier from there.

- b2: the second behaviour asked by the trainer (aplauso, belly_up, canto, giro, repeat)
analysis/data/data_retrospective_no_delay.csv: data for the trials testing retrospective memory, without delays (note that three behaviours were performed, so that the last two could be repeats to create a double repeat, this is not clear from the csv, but is fixed when the data is loaded in 06_retrospective_delay_load_data.R
- Animal: the name of the test animal (Achille, Clara, Ulisse)
- Session: the session number (1-8)

- Behaviour_2: the second behaviour asked by the trainer (belly_up, clap, repeat, sing, spin)
- Offered_2: the second behaviour offered by the dolphin (belly_up, clap, not_ask, sing, spin)
analysis/results: contains the figures (.pdf) and model outputs (.RData) from all R scripts

NOTE: each code file contains a short description. NOTE: some csv files contain typo's, these are fixed in the scripts that load them and only the corrected values are included in the meta data.
