Description

The Bavelierlab adaptation (Rioja & Denkinger, 2023, v1.1) of a Go/NoGo task from the Neuroscape ACE-X battery, built in jsPsych 7 and run in the RobbinGobblin study. Participants respond when a white square containing a smaller blue square appears at the top of the screen (Go) and withhold when the blue square is at the bottom (NoGo), at a 4100 ms SOA matched to the measured ACE-X timing. A 5-trial practice (pass ≥3 correct, up to 3 blocks, green/red fixation feedback) gates two main blocks: a sustained-attention block (160 trials, 20% Go / 80% NoGo) and an inhibition-control block (80 trials, 80% Go / 20% NoGo), in fixed order. Viewing distance is calibrated in-timeline with the jsPsych virtual-chinrest plugin, plus fullscreen and browser checks. The port replaces only the PHP save (results download as JSON) and the study-dashboard redirect.

Task Outputs

What it measures

Measure sustained attention (rare-target block) and inhibitory control (frequent-target block): commission/omission errors, RT and RT variability.

Output formats

json

One JSON download per participant: filtered jsPsych trial rows (rg-tova-data.json).

Experimental design

Trial-based

240 trials

Within-subject: block

Conditions

block

SA (160 trials, 20% Go)

IC (80 trials, 80% Go)

— Sustained-attention then inhibition-control block, fixed order, 4100 ms SOA.

Key measures for analysis

Omission errors (missed Go)
Commission errors (NoGo responses)
Mean Go RT per block
RT variability
d′ per block
