Posner Cueing Task (MATLAB / Psychtoolbox)

This repository contains a custom implementation of the Posner spatial cueing task.

🔍 Task Overview

• Implements standard Posner cueing paradigm with valid, invalid, and neutral cues.
• Includes full experiment flow: instructions, fixation, cue, target, response collection.
• Timing accuracy ensured using Psychtoolbox.
• Data are automatically logged for RT and accuracy analysis.

📁 Repository Contents

• PosnerCreative.m — main MATLAB/Psychtoolbox experiment script.
• ExampleParticipantPosnerData.xlsx — sample participant dataset (RT + accuracy).
• .gitignore — excludes large temp files (MATLAB autosave, .mat, .asv, etc.)

📊 Analysis Compatibility

The output dataset works seamlessly with:

• JASP (for raincloud plots, diffusion modeling pre-processing)
• Python (pandas, seaborn, EZ-diffusion scripts)
• MATLAB (visualization and post-analysis)

🧠 Purpose

This experiment was developed as part of Cognitive Science coursework at IIT Gandhinagar, demonstrating skills in:

• Experimental design
• MATLAB scripting
• Psychtoolbox
• Reaction-time data analysis
• EZ-diffusion modelling
