Description

Participants face a grid of 50 covered squares and have 50 picks per round to maximise their cumulative reward. Each round draws its reward sequence from a fixed file (no shuffle); the first newly-revealed square is assigned the first value, the second newly-revealed square the second value, and so on, matching the deployed LoL battery behaviour. Re-clicking an already-uncovered square returns the same value it first revealed. Three rounds are played with a brief between-round summary (score this round, running average) and a final results screen with per-round breakdown and CSV download.

Task Outputs

What it measures

Measure spatial exploration strategy, reward maximisation, and learning across repeated exposures to the same reward sequence.

Output formats

csv

One CSV per participant, one row per pick (3 rounds × 50 picks = 150 rows).

Experimental design

Trial-based

150 trials

Within-subject: round

Key measures for analysis

Total reward across rounds
Mean reward per pick (per round)
Improvement across rounds (round 3 score − round 1 score)
Mean dwell time per pick
