Preregistration

The training program was preregistered on the Open-Science Framework prior to data collection. See:

Data

The raw data in can be found in the folder data.

• Format: EyeLink .edf
• The following blocks are missing:
  • data/PP11/Phase 3/PP110307.edf
  • data/PP03/Phase 1/PP030111.edf
• The following subjects dropped out voluntarily and were replaced:
  • PP01
  • PP05
• During data analysis, participant numbers are remapped to restore contiguous numbering:
  • PP11 -> PP01 [tested as -> appears in analysis as]
  • PP12 -> PP05
  • PP10 -> PP08
  • PP08 -> PP10

Analysis

• Scripts for the analysis of Phase 1 - 3 are in the folder analysis.
• Scripts for the analysis of Phase 4 are in the folder analysis4.
• Scripts for the pupil-trace analysis (i.e. seeing how pupil size evolves over time within one cycle) are in the folder analysisTrace.

Experiment

The experiment script can be found in the folder experiment.

Pilot data

We conducted five pilot experiments. The code and results for these pilot experiments are stored in git branches exp-[nr]-[desc].
