This repository contains an Inquisit script for a modified Forward Corsi Block-Tapping Task, based on Millisecond Software’s implementation and adapted by Zoe Niesen (2024).
Unlike the adaptive version, this task uses a fixed 4x4 grid and a predetermined set of sequences (lengths 3–5). All sequences are always presented, regardless of participant performance.
- Participants view a grid of 16 boxes (4x4 layout).
- Boxes light up in a predefined sequence, which participants must reproduce by clicking the boxes in the same order.
- Sequence lengths: 3, 4, and 5 boxes.
- All sequences are presented, even if participants make errors.
- Duration: ~1 minute.
The script produces two data files per participant:
-
Raw data file (
corsiblocktappingtask_raw*.iqdat)- Device and system info
- Trial-level responses, latencies, accuracy
- Sequence and response strings
- Block span (longest correctly recalled sequence)
- Total correct sequences recalled
-
Summary data file (
corsiblocktappingtask_summary*.iqdat)- Participant/session identifiers
- Task completion status
- Block span and total score
- Fixed 4x4 grid of blocks.
- Non-adaptive — all sequences are always shown.
- Optimized for touchscreens (adapts for mouse use as well).
- Editable parameters for:
- Colors (blocks, taps, board, screen)
- Canvas sizing (absolute vs. relative)
- Timing (intervals, feedback)
- Feedback & scoring options
- Optional age question (with normative grouping from Kessels et al., 2000)
The script can be customized by editing:
- Sequence patterns
- Color scheme
- Feedback settings
- Stimulus sizing
This version may also serve as a template for other fixed-sequence memory tasks.
