MATLAB

Examines how sound affects perception of an animation. Two circles meet behind a square while a bonk or whoosh plays, and participants judge whether they bounced or passed through. The program randomizes sound conditions, records responses, and saves results.

Runs an auditory reaction-time experiment. Participants hear a tone in the left ear, right ear, or both, and press the spacebar when it plays. The program records response times, manages subject IDs, and saves results using PsychPortAudio.

Creates an interactive mood-rating tool with the Self-Assessment Manikin (SAM). The program slices icons from an image, highlights them on hover, and lets users select one to match their mood. It handles real-time mouse tracking, screen drawing, and saves the data.

This MATLAB/Psychtoolbox project measures visual change detection with mouse responses. In each trial, two blue circles appear; after a random delay, one circle briefly changes luminance (lighter or darker). Participants click the circle that changed as fast as possible. The program randomizes trial types and delays, records response times and accuracy, and saves results to a subject-specific .mat file.

Implements a reaction-time experiment in Psychtoolbox. A yellow circle changes color, shape, or position after a random delay, and participants press the spacebar as quickly as possible. The program measures response times, randomizes trials, and saves results.

Builds a simple interactive survey using Psychtoolbox. The program shows instructions, gathers input on language background, voter registration, age, and favorite color, and checks for valid responses. Results are saved to a file, demonstrating screen control, keyboard input, and data storage.

Introduces Psychtoolbox for visual display. The program opens a full-screen window, divides the screen into quadrants, and shows colored text. It also places the word 'random' in different spots and shades to demonstrate randomization, text rendering, and display timing.
