Subset of Avian Suboptimal Choice Data from Dunn et al. (2024)
Source:R/subopt_avian.R
subopt_avian.RdThis dataset contains compiled avian suboptimal choice data (pigeons and starlings) from multiple published studies that meet the inclusion criteria outlined in Dunn et al. (2024). The subset was selected for model evaluation.
Format
A data frame with 128 rows and 32 columns:
- row
Original row index in the full dataset subopt_full, retained for traceability and reproducibility.
- study
Short identifier for the study from which the data and parameters were extracted.
- year
Year the study was published.
- species
Species tested in the experiment (e.g., pigeon or starling).
- exp
Experiment number as reported in the original study. Values joined by an '&' indicate that data were aggregated across experiments.
- condition
Short label used to identify conditions within each study, aiding in dataset assembly.
- n
Number of subjects in the condition.
- cp
Observed choice proportion reported by the study.
- il_dur_a, il_dur_b
Average programmed initial link (IL) durations for alternatives A and B, respectively. FR1 schedules are assigned a duration of 1; other fixed-ratio schedules are given a duration of \(1 + (\text{ratio}/\text{run rate})\).
- tl_dur_a1, tl_dur_a2, tl_dur_b1, tl_dur_b2
Average programmed durations of terminal links. For example,
tl_dur_a1corresponds to the first terminal link on alternative A.- tl_p_a1, tl_p_a2, tl_p_b1, tl_p_b2
Probability of entering each respective terminal link.
- tr_p_a1, tr_p_a2, tr_p_b1, tr_p_b2
Probability of terminal (i.e., primary) reinforcement following entry into each respective terminal link.
- il_sched_a, il_sched_b
Schedule type used for the initial links (e.g., VI, FR).
- tl_sched_a1, tl_sched_a2, tl_sched_b1, tl_sched_b2
Schedule type used for each terminal link.
- forced_exposure
Ordinal variable describing the amount of forced exposure (FE) trials used in the study. See
Details.- DOI
Digital Object Identifier (DOI) for the original study.
- ref
Full bibliographic reference for the study.
- data_version
A character column specifying the dataset version based on the date it was last manually curated or corrected (e.g., "2025-07-20"). Used for tracking updates to the compiled data.

Details
No FE: Did not include any FE trials; Only 1 FE session at the start of the condition; FE trials for only some subjects.
Few FE: 4 - 20 FE trials at the start of each session; 6 - 12 sessions of FE at the start of the first condition in the experiment; 2 sessions at the start of each condition.
Lots of FE: FE trial following every suboptimal blackout; At least 50% of all trials were FE.
